Pain in Oral and Maxillofacial Surgery and Implant Dentistry: Types and Management

Abstract

Over the years, the pain has been defined numerous times in several ways. In oral and maxillofacial surgery, the occurrence of pain, especially postoperatively, is anticipated. Pain arises as a combination of various processes after tissue damage. Distinct pain experiences in oral surgery were depicted in several previous studies, adding knowledge to the field. The management of these encounters has been suggested over time, improving treatment approaches in the clinical setting. This review aims to understand the pain and its types and intervention in the field of oral and maxillofacial surgery.

Introduction

Pain has loosely been known to be subjective in nature.[1] This concept of pain has evolved and is usually described as sharp, dull, shooting, or throbbing because of bodily sensations. Although there are many theories of pain, such as Specificity Theory, Intensity Pattern, and Gate Control Theories, there are still questions on how pain is perceived.[2]

In 1986, the International Association for the Study of Pain (IASP) unanimously agreed that pain is defined as an “unpleasant sensory and an emotional experience with actual or potential tissue damage, or described tissue damage, or both.”[3] Recently, there have been suggestions on the new definition of pain that connotes a shared experience, aside from being unpleasant.[4] With that being stated, as of the year 2020, pain is now defined as “An unpleasant sensory and emotional experience associated with or resembling that associated with, actual or potential tissue damage.”[5]

It was believed before that pain tendency leads to recovery, as it usually is adaptive. It is known to be comprised of different systems that are harmoniously functioning to recognize pain response.[6]

According to Coulthard et al, postoperative pain is protective in nature, permitting intact wound recuperation.[7] Physiological aspects of pain render it necessary for human survival while pathologically, it pertains to a broader matter associated with the disease that caused it.[8] The pathological pain greatly influences the quality of life and opens more therapeutic challenges.[9]

In dentistry, pain has been a familiar chief complaint of every patient who suffers from it. Dentists are aware that it is their mission to relieve this experience. Moreover, dental materials and drugs were developed to address the problems associated with this condition.[10]

After treating any oral and maxillofacial surgical procedure, pain management should be essential to the oral surgeon’s clinical setting.[7] Since pain is sometimes inevitable, postoperative management continues to be a clinical dilemma even though there are advancements in the assessment and treatment of pain.[11] Being one of the most significant factors in patient compliance, the concept of pain can deter patients from visiting the dentist.[12] Understanding pain related to oral and maxillofacial surgery will help the clinician to manage it thoroughly.

This review presents the processes, pain encounters, and interventions associated with oral and maxillofacial surgical procedures.

The Pain Processes

Transmission of pain has always been thought to consist of a series of chemical mediators and neural releases that act synergistically.[13] After a noxious stimulus occurs, such as when tissue injury commences, signals are sent to nociceptors that terminates in the brain to provoke the feeling of pain. These nociceptors are bidirectional, and the primary afferent fibers with their central and peripheral terminals arise from the same axon stalk.[14]

The process of identifying and signaling the existence of noxious stimuli is called nociception.[7] The identifying involves the initiation of receptor potential caused by the primary afferent nociceptors (the A δ and C fibers), which are myelinated and unmyelinated, respectively.[14] This observable fact of activating the primary afferent nociceptors is called “peripheral sensitization.”[15] Consequently, these peripheral sensory neurons also send signals to the spinal and the supraspinal nuclei that later affect the brain.[16] They are located in the dorsal root ganglion.[17] However, in the case of the central neurons, they are situated in the spinal dorsal horn.[8]

The pain receptors involved in generating pain activate when an inflammatory reaction from an injury occurs.[18] Usual signs that go hand in hand with inflammatory pain are swelling, erythema, color, rubor, and function laesa.[19]

Pain Mediators

According to Ricciotti and Fitzgerald, inflammation is a favorable response that indicates the repair of its structure and elimination of the causative agent.[20] The inflammatory pain has a vital chemical mediator called bradykinin, which is a kinin. The kinins are processed by kininases that, if decreased, produce inflammation because of the acidic environment created.[15]

Bradykinin performs within its extent in many tissues and affects the sympathetic and sensory neurons. Its main action is to activate nociception as well as pain-production by vasodilation and smooth muscle contraction.[16] [21] Bradykinin is not only a mediator present in this process—since injury is apparent, but there are also these so-called eicosanoids that help with the production of inflammation.

Prostaglandin was said to enhance the nociceptive effects of bradykinin, thereby acting synergistically.[22] The prostaglandins are messengers at the molecular level during injury as well in the inflammatory process.[23] It is obtained from the arachidonic acid via the cyclooxygenase pathway (COX 1 and COX 2).[14] [24] This mediator is commonly viewed as a functional biological modulator that can cause inflammation. Still, according to the findings of Kawahara et al, it merely plays a crucial role in enhancing cytokine signaling. Prostaglandin was considered a robust pro-inflammatory mediator and is commonly blocked by nonsteroidal anti-inflammatory drugs (NSAIDs).[25]

On the other hand, thromboxane has an essential role in monitoring the functions of COX 2.[13] In inflammation, this eicosanoid plays a role in platelet aggregation.[17] It has been established that thromboxane aids in hemostasis and cardiovascular outcomes.

Leukotrienes, additionally, assist in vascular absorption and leukocyte chemotaxis. Both prostaglandins and leukotrienes claimed to control inflammatory pain.[25] [26]

There is a simulative neuropeptide called substance P that acts as a transmitter within the nociception system, released by bradykinin.[21] [27] It was believed to make use of chemical actions on circulatory and neural mechanisms. As a neurotransmitter, substance P is also known to emerge from primary afferent neurons from the peripheral and central nerve endings.[28] The main point of recognizing substance P is that it is a biomarker for nociceptive neurons.[20] Frequently, its presence is connected to neuropathic pain.[29] Substance P will help with the production of histamine generated by mast cells, thereby increasing vascular permeability and blood flow that causes inflammation.[30]

Acute and Chronic Pain

Acute pain happens right after an injury. A plethora of chemical mediators mentioned above comes into play immediately, resulting in pain response.[31] Peripheral and central sensitization is involved in this type of pain, and their modulation is essential to alleviate it.[32] Subsequently, chronic pain happens when the pain persisted even when the source of acute pain had been given intervention.[33] Chronic pain is a complicated occurrence that differs from patient to patient, and the intensity and characteristics can vary as well.[34]

Characteristics of Pain

The mediators discussed are crucial in recognizing the types of pain. Understanding the characteristics of pain helps in diagnosis and treatment planning. The nature of postoperative dental pain is inflammatory, nociceptive, and neuropathic in origin.[7] [35]

1. Inflammatory Pain

Inflammatory pain is produced after tissue injury as a response to actively performing vascular and nervous structures. It was known that the degree of pain commensurates to the tissue damage that was done and is precisely associated with tissue healing.[36] Moreover, the hypersensitivity sensation is also indicative of inflammatory pain.[37] The lesion would have the ability to repair itself and activates upon provocations. This, in turn, will lead to sensory reinforcement by either low or high stimuli. Since it is biological, this kind of pain can be reversed after repairing the injury unless a chronic condition intervenes.[38] Activation of prostaglandin, bradykinin, leukotrienes, histamine were exhibited, and all of which are vital for tissue repair.[7] [35] [39]

1. Nociceptive Pain

Nociceptive pain is also protective in nature, similar to inflammatory pain. Furthermore, a distinctive feature of this kind of pain is that it warns the body from further harming itself.[38] [40] Additionally, it functions as a processor of severe conditions by pressure and temperature brought about by the nociceptors.[41] Nociceptive pain exhibits a feeling of unpleasantness beyond bearable limits to maximize its protective capabilities. As mentioned earlier, these nociceptors are localized neurons that are peripherally equipped and operate as responders to noxious stimuli.[42] [43] Overflow of stimuli to nociceptors that causes injury to the central and somatic neurons can eventually lead to neuropathic pain.[29] [44]

1. Neuropathic Pain

Neuropathic pain, as redefined by NeuPSIG and the International Association of the Study of Pain, is the “pain arising as a direct consequence of a lesion or disease affecting the somatosensory system.” This entails that the pain comes from the lesion emerging from the peripheral or central nervous system.[38] [45] The associated peripheral disorders that lead to the progress of neuropathic pain are damages in the dorsal root ganglia and the spinal nerves.[44] Neuropathic pain is described as burning, tingling, and stabbing sensations.[35] It is usually maladaptive, and many patients have complained about it to be persistent.[38] [43] Contributing factors for this type of pain are the severity of the disease leading to chronicity and the time of surgery.[46] Nociceptors such as A-delta, C unmyelinated with A-beta fibers are involved with a high degree of exposure.[47] Compared to inflammatory and nociceptive pain, this pain is due to the ailments in neural structures.[40] Since it is not protective in nature, Klasser and Gremillion claimed that neuropathic pain does not support healing and repair.[38]

1. Peripheral Painful Traumatic Trigeminal Neuropathies

Associated with neuropathic pain is peripheral painful traumatic trigeminal neuropathies (PPTTN), which occurs 3 months after surgical involvement. Tendencies of PPTTN were attributed to nerve injuries (e.g., trigeminal nerve) after treatment.[35] [40] Often described as constantly burning and sometimes shooting pain, Sougoumarin et al mentioned that PPTTN also develops from peripheral to the central nervous system according to the IASP.[48]

According to Al-khateeb and Alnahar, prior research unanimously agrees that the patients undergoing minimally invasive surgeries such as uncomplicated tooth extraction, flapless surgeries, and small mucoperiosteal flaps have less postoperative pain, unlike traumatic dental and osseous surgeries.[49] Understandably, the progression of acute pain to chronic pain is presented with multiple factors.[50] It is also important to note that because of postoperative pain, the patients are postponing the visits to the dental setting.[51] The pain in oral surgery usually starts as soon as the anesthetic diminishes within the day.[52]

Dental Pain

When the tooth becomes inflamed or traumatized, different types of pain mediators conglomerate, and the sensation is perceived as painful.[53] The stimuli can activate sensory pain systems, especially in the dentin. The phenomenon has led to various theories, such as the hydrodynamic theory, in which the fluid in the dentinal tubules move, causing pain and is also known to have ion channels that contributed to tooth pain.[54] As usual, the pain that can be felt varies from person to person, and it has different characteristics. The toothache is the most common acute pain in dentistry, alongside pericoronitis, alveolar osteitis, and apical periodontitis.[53]

Oral and Maxillofacial Procedures Causing Pain

Several oral and maxillofacial surgery procedures cause pain, most likely in the postoperative period, when the healing process commences. The following procedures are described:

1. Simple Extraction

Simple extractions are the most frequently performed procedures in the oral surgery field at dental clinics. The pain is predicted to be less intense in these procedures than complicated ones, as it is of inflammatory type.[55] The tooth’s precondition is also accounted for: the more inflamed and damaged tooth will consequentially be, the more painful the tooth postoperatively.[49]

In 1990, a study by Kim presented that C fibers are overstimulated with inflamed pulp than the sound tooth.[56] This indicates that neuropathic pain can happen in simple extractions as well.[57] Likewise, incisions from a scalpel are suggestive of nociceptive pain, which can taper off as the incision ends.[37] Noxious stimuli can also be experienced by mechanical sectioning of the tooth as it produces heat and friction.[56]

In a study dedicated to premolar extractions by Chaushu et al, the authors documented swift healing; the pain was not a major predicament for 2 days.[58] Persistent pain can also be expected but can be attributed to problems in the healing of the socket rather than nerve involvement.[59]

1. Periapical Resection

Chong and Pitt Ford’s study showed that postoperative pain during root-end resection is sensed more during the first 3 to 5 hours, which reduces gradually.[60] Slight pain and inflammation were described by Penarrocha et al during the first few days after apical surgery. The number of teeth and operation time were also considered factors with the expected degree of pain.[36] Similarly, Kvist and Reit showed the same results as postoperative pain after the surgical retreatment of endodontic cases.[61] Additionally, according to an analysis by García et al, the pain is intensified when the patient smokes, has poor oral hygiene, and when there was pre-existing pain before the periapical surgery.[62]

1. Third Molar Surgery

In cases of third molar surgeries, rare and severe complications often occur when the lingual nerve and inferior alveolar nerves get involved.[63] Nerve injury was attributed to the operator’s experience, use of improper armamentaria, and depth of impaction as the most critical factor.[64] According to Berge, 1 to 5% of the patients who undergo surgical removal of impacted third molars have chronic neuropathic pain, which is less than those reported by the IASP.[65] The pain nonetheless depends on the flap design with envelope flap, tooth sectioning, and vertical angulation related to less pain.[66]

However, in 2010, Sandhu et al reported that severe pain was experienced with the envelope flap compared to a bayonet flap for third molar surgery.[67] As far as the depth of impaction is concerned, position C was said to be correlated with severe pain in retrospect.[68] The surgical time was also discussed to be a factor, naming that the lengthier the procedure, the more pain sequelae are expected because more inflammatory processes come into play.[69] [70]

1. Alveolar Osteitis

Alveolar osteitis is a known complication in both routine exodontia and third molar surgery.[71] [72] [73] Described to be a problem where there is a displacement of the blood clot and fibrinolysis, it occurs within 3 days after surgical intervention.[52] [73] [74] Usually termed as “dry socket,” it is characterized by intense pain, lasting from five to ten postoperative days.[75] Thirty-eight percent of mandibular third molars are stated to have alveolar osteitis, compared to routine extractions.[76] In a study by Benediktsdóttir et al, it was found that females were more at risk of experiencing dry sockets associated with pain than males.[63] In a systematic review by Riba-Terés et al, it was inferred that bacteria might play a role in the pathogenesis of this condition.[77]

1. Implant Placement

Implant placement could cause neuropathic pain. Perioperative factors such as placement near the inferior alveolar nerve, causing a breach to its roof can ensue the neuropathic pain. According to Renton et al, paresthesia of the lower lip was a common problem while neuropathy was only secondary.[78] In a review and case report by Rodriquez-Lozano et al, maxillary implant installation can also give rise to neuropathic pain as well.[79] Generation of heat while placing the implant can be a factor and can be coupled with nerve injury.[35] [78] In contrast, Porporatti et al in 2017 reported that persistent pain was not exhibited by their subjects.[80] Moreover, a 2020 study by Tabrizi et al reported that 40 patients who underwent both tooth extraction and dental implant surgery perceived dental implant placement as less painful.[81]

1. Alveoloplasty

In a case report by Yoo et al in 2015, routine alveoloplasties can also cause inflammation in the nerves causing neuropathic pain. The inflammation is due to the trauma and other somatosensory disorders encountered during the procedure.[82] Alveoloplasty, when associated with emphysema because of the use of high-speed handpieces, can also cause severe pain and discomfort with crepitus on palpation, as reported by Dodge et al.[83]

1. Orthognathic Surgery

A study by D’ Agostino et al reported insignificant pain and discomfort after orthognathic surgery. But 76% of the subjects experienced localized alteration of facial sensations.[84] Bilateral sagittal split osteotomy (BSSO), on the other hand, was reported to have neuropathic pain in only 0.51% of the patients indicating that it has less risk of impinging the trigeminal nerve upon operation according to Politis et al in 2014.[85] However, according to Kim, possible neuropathic pain was from exposing the inferior alveolar nerve and the structures within its extent.[86] Furthermore, it was emphasized that BSSO and Le Fort I osteotomies simultaneously have more tremendous pain than other procedures in the oral and maxillofacial surgery field.[87] Neuropathic pain can be concluded as a direct aftermath of orthognathic surgery and trauma.[88] Additionally, the pain was experienced by orthognathic surgery patients after a year with temporomandibular joint problems.[89] The major structures that can be injured are the inferior alveolar nerve, mental nerve, incisive nerve, and the infraorbital nerve, and can have tremendous permanent damages.[86]

1. Head and Neck Malignancy

Malignancies in the head and neck region are essential for understanding the pain process. In a study with different oral pathologies by Eliav et al, the authors emphasized that the presence of malignancies can cause Aβ afferents that may trigger inflammatory signaling, which may damage nerves in the oral region.[47] On the other hand, oral metastasis is another entity featuring an undetected complication, they grow progressively and cause pain, among other symptoms.[90]

1. Oral and Maxillofacial Trauma

Oral and maxillofacial traumas typically need surgical interventions because of the presence of fractures in the mandible and the maxilla. In a retrospective study by Wusiman et al, these traumas are likely to happen more to young adults, and vehicle accidents are most likely the cause.[91] The pain was noted to be the primary concern after the trauma and surgical involvement, significantly when the temporomandibular joint is affected.[92] [93] [94] The quality of life of the patients who underwent invasive approaches deteriorated for the first 3 months after the operation.[94] Facial fractures together with orthognathic surgery also predispose to post-traumatic neuropathy that can be iatrogenic.[33]

Pain Assessments

Visual analogue scale (VAS) is used in most of the studies that assess pain in oral, maxillofacial, and dental implant surgeries. VAS can be used preoperatively and more so postoperatively from the first to the seventh day, arbitrarily. This scale has an intensity range from 0 to 100 (no pain to worst pain). The pain scores are rather subjective as the patient indicates the pain based on his experience.[11] The measurement validity is somewhat questionable, but with repeated application, reliability can be gained.[95] [96] Other studies rely on the use of analgesics alone or with the pain scale of their choice; the fewer the analgesics used, the lesser is the pain perceived by the patient.[97] [98]

Treatment for Acute Pain

Since dentoalveolar surgery is the first and foremost framework of oral maxillofacial surgery, common pain relief agents are recommended.[55] Nonopioid pain treatment such as acetaminophen (paracetamol) is known to have therapeutic effects on mild to moderate pain with added anti-inflammatory outcomes that can be used for postoperative pain.[99] Al-khateeb and Alnahar also mentioned that commonly used postoperative medications are paracetamol and NSAIDs in extraction cases, and they recommended prescribing them in the first week.[49] Since this operation commonly involves acute pain, simple, single dosed pharmacologic interventions are enough to be prescribed.[100]

The low-level laser therapy was also found to be effective in this type of surgery. According to Mozzati et al, super pulsed low-level laser after bilateral molar extractions is successful in lessening the pain because it inhibits inflammatory cytokines, suppresses cyclo-oxygenase 2 (COX₂), and activates bone remodeling that is beneficial in wound healing.[101]

Transdermal patches were used by Bhargava et al as a new method of pain control after routine tooth extractions. They compared ketoprofen and diclofenac patches with the ketoprofen patch demonstrating a more remarkable effect on pain, as the patients did not need any analgesics when applied.[102]

Single-dose analgesics are usually prescribed for pain from periapical surgeries, mostly experienced after 1 day. Tsesis et al used acetaminophen or naproxen sodium as their monotherapy.[103] In another study by García et al, ibuprofen 600 mg every 8 hours for 4 days was used for acute pain, and in severe pain, magnesium metamizole 575 mg was used as needed. They focused on smokers and poor oral hygiene, and minimal pain was exhibited with the medications prescribed.[104] Moreover, corticosteroids like dexamethasone had also been tried in this type of surgical procedure. Lin et al stated that dexamethasone and etodolac, nonsteroidal anti-inflammatory drugs, produce less pain and discomfort.[105] Most third molar surgeries’ pain control only requires analgesics for acute pain. Nevertheless, this was deemed to be inadequate sometimes for some patients. Combining medications, aside from single analgesic doses, are also evident to be effective in relieving pain after third molar removal operations. The aim is to decrease the doses of the drugs while simultaneously achieving sufficient analgesia, lessening the chances of adverse drug reactions.[51] [106] In terms of analgesics, the combination comprises a peripherally acting drug and a centrally acting drug. An example would be acetaminophen and ibuprofen or diclofenac, or ketoprofen.[107]

In 2016, in a study done by Orozco-Solís et al, meloxicam 15 mg was used preoperatively. It was reported that it produced a successful reduction of pain compared to diclofenac 100 mg after the third molar operation.[108] Tramadol usage has also been suggested in many studies as an efficient pain reliever after third molar surgeries.[109] [110]

However, not only combination analgesics have been reported to enhance pain relief. Additionally, corticosteroids can also help. Corticosteroids also play a role in alleviating pain in oral and maxillofacial surgeries since they are known to suppress the cyclo-oxygenase and the lipoxygenase pathways.[111] Corticosteroids like prednisolone, dexamethasone, methylprednisolone with analgesics are evidenced to maximize pain relief. These drugs are well documented, and the postoperative results have been promising.[112] According to other literature, dexamethasone is applied via different routes in third molar surgeries, with the submucosal route showing superior effects.[113] [114] [115] [116] [117]

Platelet rich fibrin (PRF) in third molar surgery was involved in a randomized clinical trial in 2015, resulting in no significant differences of pain in the intervention and the control areas.[118] However, a study by Al-Hamed et al in 2016 with PRF said that it decreased pain more than promoting soft tissue healing,[119] the mechanism of which includes the promotion of blood clots since this material is filled with growth factors and cytokines needed for recovery and pain reduction.[120] [121]

Typically, the management of alveolar osteitis includes analgesic and antibiotic therapy and topical dressings.[77] Recently, a new literature trend also indicated the use of PRF in treating this condition. A clinical trial by Sharma et al in 100 patients with alveolar osteitis proved that PRF can be useful in pain relief and wound healing.[122] PRF was also compared with Alvogyl, a known antiseptic dressing indicated for alveolar osteitis, and results have shown that they have the same effect in reducing pain and enhancing healing.[75] The evidence has deemed PRF to be a promising treatment modality in treating dry sockets.

Another clinical study was done in pain alleviation of dry socket, in which they used concentrated growth factor (CGF) and low-level laser therapy. With 60 patients in their study with one tooth involving dry socket, CGF was more successful than the low-level laser therapy.[123]

Treatment for pain after implant placement typically necessitates NSAIDs as the first line of pain control medication. Ibuprofen alone can be used after dental implant placement.[124] Corticosteroids can also be used to lessen other postoperative sequelae.[125] According to Bahammam et al, dexamethasone given preoperatively and postoperatively evidently reduces pain.[126] In 2006, a study by Buyukkurut et al, prednisolone 25 mg with diclofenac given after surgery successfully minimized pain, swelling, and trismus.[127] Methylprednisolone 40 mg single dose injected in the masseter muscle in impacted third molars immediately after surgery was also deemed to be successful in postoperative sequelae.[128]

Alveoloplasty is usually associated with postoperative acute pain, thereby regular analgesics can be prescribed. From the case report of Dodge et al, the dentist prescribed prednisone and meloxicam among other medications.[83]

Preoperative tramadol and diclofenac sodium can also be used to promote postoperative analgesia in bimaxillary osteotomies.[87] One observational study by Mobini et al in 2018 mentioned that analgesics for 24 hours are usually acetaminophen, oxycodone, and hydromorphone.[129] The last two drugs are opioid analgesics, used for severe types of pain. Subsequently, opioids are suggested to be used with NSAIDs rather than taking them alone for maximum analgesic effect and less adverse reactions.[130]

Corticosteroids have also been routinely used in orthognathic surgery either preoperatively or postoperatively.[131] A study by Abukawa et al in 2017 also advised the use of dexamethasone for BSSOs at 16 mg intravenous route.[132]

Low-level laser therapy in BSSO and Le fort 1 was also reported by Gasperini et al The study showed an enhanced reduction of pain on succeeding follow-up days.[92] By the evidence presented for osteotomies, we can extrapolate the same interventions for head and neck malignancies and facial traumas.

Treatment for Persistent Pain

Chronic pain treatment modalities are more complicated than acute pain that is usually expected in different surgical techniques above. In patients experiencing neuropathic pain following nerve injury and other iatrogenic factors from various procedures, analgesics can be recommended with other medications that can lessen pain.[35] [133] With all the pharmaceutical approaches that can be used hand in hand with analgesics, the British Dental Journal preferred using topically-applied treatments as an initial remedy before trying other methods.[134] Moreover, gabapentin, carbamazepine, and tricyclic antidepressants were also known to reduce neuropathic pain with analgesics.[82] [135]

The first line of drug treatments are tricyclic antidepressants, serotonin-noradrenaline reuptake inhibitors (SNRI), and anticonvulsants: pregabalin and gabapentin.[136] Tricyclic antidepressants are known to inhibit neuropathic pain since they do not encourage suppressed pain and anxiety.[137] Their action is nonselective and depends on the peripheral fibers in the dorsal root that supplies noradrenaline, a hormone highly regarded in the study of neuropathic pain because of its analgesic effect.[137] [138] However, SNRI has also been an effective modality without the side effects that come with the use of tricyclic antidepressants. Duloxetine is an example of an SNRI that can be well used in neuropathies associated with chemotherapy, which might be useful in head and neck cancer.[139] Additionally, gabapentin and pregabalin are also efficient in neuropathic pain and well-tolerated as they decrease the influx of some monoamine neurotransmitters.[138] [140] Tramadol was also mentioned by studies to be proven effective in postoperative analgesia for neuropathic patients with chronic orofacial pain.[33] [136] [141] Furthermore, Murnion particularly recommends tricyclic antidepressants and SNRI first, gabapentin and tramadol second if the first two are inadequate in relieving neuropathic pain.[136]

A systematic review by de Pedro et al on the use of low-level laser therapy suggested that it can be an effective modality in relieving orofacial neuropathic pain, but it needs further studies and more standardized methods.[142] Moreover, in a general sense, the use of low-level laser therapy had encouraging results, in congruence with the review of de Pedro et al.[143]

In conclusion, different mechanisms are transpiring to produce pain. Pain-related to oral and maxillofacial surgeries and implant dentistry is unavoidable postoperatively, and it is important to know the mechanism and management of each. Various treatment modalities have been studied over time by researchers. Nonetheless, further studies about the pain linked with oral and maxillofacial surgery and implant dentistry and complex pain cases connected to oral surgery are recommended to equip clinicians in diverse settings. Many previous clinical studies with pain measurement and treatment in oral and maxillofacial surgery are summarized in [Table 1].[35] [79] [82] [92] [106] [108] [119] [121] [126]

Limitations

The review covers available literature related to pain in oral, maxillofacial surgery, and dental implant placement. Most of the literature vaguely explained the nature of pain, thereby just describing the process. Limited evidence is available for simple extractions; mostly case reports with unusual outcomes, but these are indeed expected.

In third molar surgeries, many combination drugs were used under randomized clinical trials that were not included in this study in detail because of varying outcomes. Corticosteroid use in extensive surgeries has scarce evidence. Finally, it was difficult to find literature on chronic pain related to oral and maxillofacial surgery.
