Temporomandibular Joint Disorders and the Eating Experience.

Temporomandibular joint disorder (TMD) is a chronic disorder that significantly affects oral function. It can affect appetite and the mechanical components involved with eating, including mandibular opening, biting, chewing, and even swallowing. Thus, dietary intake and, subsequently, nutrition status are affected.

Sensory Changes Related to Dental Implant Placement: A Scoping Review.

Aims: To perform a scoping review of the literature to elucidate the occurrence of nerve damage related to dental implant placement and the factors causing the sensory changes.

Methods: An extensive electronic search was conducted using the Cochrane Library, Medline via Ovid, PubMed, Wiley Online, Science Direct, CINAHL, and the Google Scholar databases from the year 1950 to 2020.

Results: The search resulted in 1,067 articles, out of which 76 were selected for this review.

Genetic variation in catechol-O-methyltransferase is associated with individual differences in conditioned pain modulation in healthy subjects.

Background: Genetic variation in the catechol-O-methyltransferase (COMT) gene is associated with sensitivity to both acute experimental pain and chronic pain conditions. Four single nucleotide polymorphisms (SNPs) have traditionally been used to infer three common haplotypes designated as low, average and high pain sensitivity and are reported to affect both COMT enzymatic activity and pain sensitivity. One mechanism that may partly explain individual differences in sensitivity to pain is conditioned pain modulation (CPM).

World Workshop in Oral Medicine VII: Reporting of IMMPACT-recommended outcome domains in randomized controlled trials of burning mouth syndrome: A systematic review.

Objectives: To determine the frequency of use of the core outcome domains published by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) in burning mouth syndrome (BMS) randomized controlled trials (RCTs).

Methods: This systematic review, conducted as part of the World Workshop on Oral Medicine VII (WWOM VII), was performed by searching the literature for studies published in PubMed, Web of Science, PsycINFO, Cochrane Database/Cochrane Central, and Google Scholar from January 1994 (when the first BMS definition came out) through October 2017.

Results: A total of 36 RCTs (n = 2,175 study participants) were included and analyzed.

World Workshop on Oral Medicine VII: Burning mouth syndrome: A systematic review of disease definitions and diagnostic criteria utilized in randomized clinical trials.

Objective: To conduct a systematic review analyzing disease definitions and diagnostic criteria used in randomized controlled trials (RCTs) involving burning mouth syndrome (BMS).

Methods: A systematic search conducted in PubMed, Web of Science, PsycINFO, Cochrane Database/Cochrane Central, and Google Scholar that included RCTs on BMS published between 1994 and 2017 was performed.

Results: Considerable variability in BMS disease definitions and diagnostic criteria used created substantial heterogeneity in the selection of participants and weakened the rigor of the 36 RCTs identified.

The Effect of Nonstrenuous Aerobic Exercise in Patients with Chronic Masticatory Myalgia.

Aims: To evaluate the effect of nonstrenuous aerobic exercise on chronic masticatory myalgia (CMM) patients and healthy controls (HC) by means of mechanical temporal summation (TS) and response to mechanical stimulation (RMS) performed on the dominant forearm.

Methods: A total of 30 patients diagnosed with CMM and 30 pain-free HCs were first evaluated for maximum number of steps (MNS) on a stepper machine for 1 minute. Additionally, they completed the Generalized Anxiety Disorder (GAD-7), Graded Chronic Pain Scale (GCPS), and Jaw Functional Limitation Scale (JFL) questionnaires.

Orbital pseudotumor presenting as a temporomandibular disorder: A case report and review of literature.

Background And Overview: Orofacial pain has multifactorial causes and is often a diagnostic challenge. Misdiagnosis can result in morbidity or mortality due to misdirected and inappropriate treatment. A delay of necessary treatment, in cases of ominous illnesses, may result in its perpetuation or progression.

Primary burning mouth syndrome: Literature review and preliminary findings suggesting possible association with pain modulation.

Primary burning mouth syndrome (BMS) is a chronic pain of a burning quality affecting the tongue and intraoral mucosa. Currently, there are no definite diagnostic criteria; therefore, the diagnosis is made by exclusion of potential local and systemic causes that could justify the burning sensation. The etiology behind primary BMS remains unclear; however, the most acceptable theories link primary BMS with neuropathic pain.

Continuous neuropathic pain secondary to endoscopic procedures: report of two cases and review of the literature.

Neuropathic pain encompasses a spectrum of conditions that can arise from a lesion or dysfunction of the central or the peripheral nervous system, and it may develop at variable intervals after nerve injury or inflammation. Nerve injuries arising from surgical procedures commonly occur secondary to the surgical trauma, and in rare instances they are a complication of intubation during general anesthesia or endoscopic procedures. A series of 2 cases of bilateral glossopharyngeal neuropathic pain subsequent to endoscopic procedures is presented with a review of the literature concerning the mechanisms of development of neuropathic pain after these procedures.

What should we tell patients with painful temporomandibular disorders about what to eat?

Background And Overview: Patients with painful temporomandibular disorders (TMD) commonly report problems eating, owing to limited mandibular opening and pain and discomfort with biting and chewing. Consequently, painful TMD may affect dietary intake and nutritional status.

Conclusions: Treatment of painful TMD is multifaceted and involves pharmacologic, physical, and cognitive behavior and dietary therapies.

Burning mouth syndrome: Current concepts.

Burning mouth syndrome (BMS) is a chronic pain condition. It has been described by the International Headache Society as "an intra-oral burning or dysesthetic sensation, recurring daily for more than 2 h/day for more than 3 months, without clinically evident causative lesions." BMS is frequently seen in women in the peri-menopausal and menopausal age group in an average female/male ratio of 7:1.

Altered pain modulation in patients with persistent postendodontic pain.

Persistent pain may follow nerve injuries associated with invasive therapeutic interventions. About 3% to 7% of the patients remain with chronic pain after endodontic treatment, and these are described as suffering from painful posttraumatic trigeminal neuropathy (PTTN). Unfortunately, we are unable to identify which patients undergoing such procedures are at increased risk of developing PTTN.

Combined palliative and anti-inflammatory medications as treatment of temporomandibular joint disc displacement without reduction: a systematic review.

The aim of this study was to evaluate the efficacy of self-care combined with anti-inflammatory medications in the treatment of temporomandibular joint (TMJ) pain associated with disc displacement without reduction (DDWOR). A systematic review of randomized clinical trials was done by the authors. The databases searched were Medline (1966 to July 2012); EMBASE (1980 to July 2012); and LILACS (from 1982 to July 2012).

Topical medications as treatment of neuropathic orofacial pain.

Understanding mechanisms of neuropathic orofacial pain, targets of treatment, and basic pharmacology and working with informed compounding pharmacists may result in significant benefit for patients. The clinical significance of topical medications is improvement of quality of life for patients by providing a unique medication delivery system for neuropathic orofacial pain and other dental and extraoral conditions. The use of this route of administration has decreased or minimized side effects compared with other methods and is especially useful in medically compromised and elderly patients.

Complex regional pain syndrome following trigeminal nerve injury: report of 2 cases.

Complex regional pain syndrome (CRPS) is a debilitating neuropathic pain condition that has been extensively reported in the extremities following variable degrees of nerve trauma. CRPS has rarely been reported in the orofacial region. We report 2 orofacial pain patients whose clinical phenotypes fit the criteria for CRPS.
