RESUMEN
BACKGROUND: During third molar removal, the mandible is supported by a dental assistant (DA) to counter downward forces during surgery, and with sedation, to maintain airway patency. The Restful Jaw device (PEP Design; Saint Paul) provides this support instead of the DA. PURPOSE: This study compared the occurrence of postoperative preauricular and masticatory muscle pain symptoms (PMMPS) between the device and DAs providing mandibular support, using two outcome measures. Secondary aims identify predictors of outcome and providers' opinions of the device. STUDY DESIGN, SETTING, SAMPLE: In this multisite, single-blind, two-arm parallel randomized trial, participants without preoperative PMMPS had surgical removal of third molars, with sedation and bite blocks were randomly assigned to manual support or the device. EXPOSURE VARIABLE: The exposed group was randomly assigned to the device and the nonexposed group to manual support. MAIN OUTCOME VARIABLE(S): The primary outcome was patient-reported PMMPS. Two secondary outcomes were pain assessed with the temporomandibular disorder Pain Screener and providers' views on the device. Outcomes were assessed at 1-, 3-, and 6-month postsurgery. COVARIATES: The covariates are baseline demographics (eg, sex), clinical characteristics (eg, eruption status), and third molar surgeries. ANALYSES: For occurrence of pain, generalized estimating equations assessed differences between groups. Logistic regression analysis assessed predictors of pain at 1 month, per the Screener. The level for statistical significance was 5%. RESULTS: Enrollment was 86 and 83 participants in the device and DA groups, respectively. The average age was 20.8 years; the majority were female (65%) and Caucasian (66%). The retention rate was ≥95.9%. The groups did not differ significantly for occurrence of pain using the primary and secondary outcome measures at any follow-up (P ≥ .46). Fully impacted molars were associated with occurrence of pain (odds ratio = 3.44; 95% confidence interval 1.49-7.92; P = .004). CONCLUSION AND RELEVANCE: Occurrence of pain using the primary and secondary outcome measures did not differ significantly between groups at any follow-up and was associated with removal of fully impacted third molars. Four out of five surgeons reported wanting to use the device on a regular basis when performing this procedure in sedated patients.

BACKGROUND: Because of controversial results from clinical studies comparing different dental local anesthesia methods in children, the primary objective of this randomized, split-mouth, crossover, controlled trial was to compare pain intensity during local anaesthesia (LA) performed with a computer-controlled LA delivery system (C-CLADS) versus a conventional syringe (CONV). Secondary objectives included comparisons during dental treatment. METHODS: Participants (4-8 years) with tooth pair requiring similar treatment were recruited from five French hospitals. The right primary molar, which was treated at the first visit, was randomly allocated to one of the anaesthesia groups (either intraosseous with C-CLADS or infiltration with CONV), whereas the contralateral molar (treated at the second visit) was assigned to the other group. Pain intensity and behaviour outcomes, assessed with the Faces Pain and Venham revised scales, respectively, were compared between groups using Proc mixed. Stratified analyses were performed on dentition and location. RESULTS: Among 107 participants, the analysis revealed reduced pain perception during LA in the C-CLADS group compared with the CONV group (-0.72, 95% CI: -1.43, -0.006), but not during dental treatment. Stratified analyses showed that this effect was observed only in primary dentition (p = .006) and mandibular molars (p = .005). Behavioural issues were fewer in the C-CLADS group than in the CONV group (p = .05) only during injection. CONCLUSION: C-CLADS emerged as the preferable system in primary dentition.
RESUMEN
BACKGROUND: This systematic review investigated the prevalence of orofacial pain in patients with mild cognitive impairment (MCI) or dementia. MATERIALS AND METHODS: The search was conducted in five databases (Medline (Ovid), Embase (Ovid), CINAHL, Scopus and LILACS), in three grey literature sources and in included articles' reference lists. Three independent reviewers performed study selection, quality appraisal and data extraction. The risk of bias was assessed with the National Institutes of Health tool. Prevalence was calculated using the random-effects model. Subgroup analysis and meta-regression were used to explore the heterogeneity of results. RESULTS: The database and grey literature search led to 12 246 results, from which nine studies were included; a further four were selected through citation searching. The total sample comprised 6115 patients with dementia and 84 with MCI. All studies had high risk of bias. The overall estimated pooled prevalence of orofacial pain among dementia participants was 19.0% (95% CI, 11.0%-27.0%; I 2, 97.1%, P < .001). Only one study included MCI participants, among which the prevalence of orofacial pain was 20.5%. Subgroup analysis demonstrated that the different sources of diagnosis might explain the heterogeneity. A higher prevalence of orofacial pain was observed in dementia participants aged over 80 years or living in nursing homes. Meta-regression analysis showed a nonlinear relationship between age and the prevalence of orofacial pain. CONCLUSIONS: The pooled data from the primary studies revealed that 2 out of 10 patients with dementia have orofacial pain. Further research is needed to clarify the magnitude in individuals with MCI.

INTRODUCTION: The objective of this study was to assess an original learning intervention to train students and paediatric dentistry teachers in radiographic diagnostic accuracy of pulpo-periodontal complications in primary molars. MATERIALS AND METHODS: The learning intervention was based on 250 different randomly ordered radiographs of primary molars within three quizzes (A, B and C) for 5 sessions (S): quiz A (50 X-rays), B and C (100 X-rays) were, respectively, completed in S1 to assess the extent of agreement with 5 experts' diagnoses, in S2 and S3 (B at days 8 and 23) and in S4 and S5 (C at days 90 and 105). During S1 and at the end of S3 and S5, the participants (48 students and 16 teachers) were informed of correct diagnoses. A satisfaction questionnaire was completed by all the students. Alongside the descriptive analyses, generalised linear mixed model (GLMM) analyses assessed the odds of participants' correct diagnosis over the study duration. RESULTS: At S1, the odds of diagnostic accuracy among students were significantly lower than those among the teachers. After receiving feedback at S1, GLMM analyses showed that among all the participants, accuracy improved over time with the odds of correct diagnoses higher in S2-5 than in S1; and there were similar increases across sessions between teachers and students, except in S3, where the improvement among teachers tended to be greater than that among the students. All students were satisfied though one-third reported that quizzes with 100 radiographs felt too long. CONCLUSION: The online case-based learning was a good training format for dental education.

BACKGROUND: Temporomandibular disorder (TMD) pain is common among adolescents. The association between painful TMD and other comorbidities has been demonstrated. However, the difference between short-term (<6 months) and long-term (≥ 6 months) painful TMD is not yet clear. OBJECTIVE: The aim of this study was to assess the association between comorbidities and short- and long-term painful TMD among adolescents. METHODS: In this cross-sectional study, adolescents were recruited from Montreal (Canada), Nice (France) and Arceburgo (Brazil). Self-reported painful TMD, comorbidities, school absence and analgesic intake were assessed using reliable instruments. Multivariable logistic regression analyses were conducted to assess the study aims. RESULTS: The prevalence of short- and long-term painful TMD was estimated at 22.29% and 9.93% respectively. The number of comorbidities was associated with short- (OR = 1.71, 95%CI = 1.53-1.90) and long-term painful TMD (OR = 1.79, 95%CI = 1.55-2.08) compared to controls. Frequent headaches (ORshort-term = 4.39, 95%CI = 3.23-5.98, ORlong-term = 3.69, 95%CI = 2.45-5.57) and back pain (ORshort-term = 1.46, 95%CI = 1.06-2.03, ORlong-term = 1.69, 95%CI = 1.11-2.59) were associated with both painful TMD groups. Frequent neck pain (OR = 2.23, 95%CI = 1.53-3.26) and allergies were only associated with short-term painful TMD (OR = 1.54, 95%CI = 1.13-2.10). Frequent stomach pain was related to long-term (OR = 2.01, 95%CI = 1.35-3.26), and it was the only comorbidity significantly more frequent among the long than short-term TMD (OR = 1.82, 95%CI: 1.14-2.90). These analyses were adjusted by sex, age and city. CONCLUSION: In this multi-centre study, both short- and long-term painful TMD are associated with frequent headaches and back pain, whereas frequent neck pain and allergies are related to only short-term and frequent stomach pain with long-term painful TMD.

BACKGROUND: Worldwide, numerous surveys have investigated practices and knowledge about caries management in adults, but few are available for children. AIM: The present cross-sectional survey aimed to assess the restorative thresholds (RTs) in primary and permanent molars in children used by a population of dentists treating children and practicing in France. DESIGN: The study population consisted of French dentists treating children (Fr-DTCs) who were registered in the French Society of Pediatric Dentistry (n = 250). A specific questionnaire was developed. Descriptive and statistical analyses were performed. RESULTS: Response rate was 80.4% (n = 201). Considering that an appropriate RT is at the stage of a moderate lesion (occlusal: International Caries Detection and Assessment System 4; approximal: lesion involving the external third of dentine), more than 50% of respondents showed a tendency for iatrogenic treatment, except for occlusal carious lesions in primary molars. Inappropriate invasive strategies were more often reported for occlusal lesions in permanent than primary molars. Moreover, for both molar types, these inappropriate RTs were more often chosen for approximal than occlusal lesions. CONCLUSIONS: The present survey suggested that Fr-DTCs tend to overtreat in terms of caries management in both primary and permanent molars.

BACKGROUND: Painful temporomandibular disorder (TMD) is common among adolescents. Presence of painful comorbidities may worsen painful TMD and impact treatment effectiveness. OBJECTIVE: The aim of this study was to assess the association between painful TMD and comorbidities. METHODOLOGY: In this cross-sectional study, adolescents were recruited in Montreal (Canada), Nice (France) and Arceburgo (Brazil). Reliable instruments were used to assess painful TMD and comorbidities. Multivariable logistic and linear regression analyses were conducted to assess the study aims. RESULTS: The prevalence of self-reported painful TMD was estimated at 31.6%; Arceburgo (31.6%), Montreal (23.4%) and Nice (31.8%). Painful TMD was more common among girls than boys (OR = 1.96). Painful TMD was associated with a higher number of comorbidities (OR = 1.77); Arceburgo (OR = 1.81), Montreal (OR = 1.80) and Nice (OR = 1.72). A stronger association was found between painful TMD and headaches (OR = 4.09) and a weaker one with stomach pain (OR = 1.40). Allergies were also related to painful TMD (OR = 1.43). CONCLUSION: Painful TMD was associated with comorbidities. Headaches were consistently associated with painful TMD. Other associations were modified by sex and/or covariates related to the cities where participants were recruited.

OBJECTIVES: The aim of this systematic review (SR) was to answer the following question: "In adult patients with temporomandibular disorder (TMD)-related pain, what is the placebo or nocebo effect of different therapies?" METHODS: A SR was performed with randomised clinical placebo-controlled trials on diagnosed painful TMD studies from five main databases and from three grey literature. Studies included must have sample older than 18 years, with painful TMD, which diagnosis was done by Research Diagnostic Criteria (RDC/TMD) or Diagnostic Criteria (DC/TMD). RESULTS: Out of 770 articles obtained, 42 met the inclusion criteria for qualitative and 26 for quantitative analysis. Meta-analysis indicated mean variation on pain intensity for placebo therapy was higher on laser acupuncture with 45.5 mm point reduction, followed by avocado soya bean extract with 36 mm and amitriptyline 25 mg with 25.2 mm. Laser showed a 29% of placebo effect, as well medicine with 19% and other therapies with 26%. Possible nocebo effect of 8% pain increase was found for intra-articular injection of Ultracain. CONCLUSIONS: Based on the available data, the placebo response could play a major effect on TMD pain management and may be responsible from 10% to 75% of pain relief. Laser acupuncture, avocado soya bean and amitriptyline promoted the higher placebo effect. Possible nocebo effect was found only for Ultracain injection with 8%. CLINICAL RELEVANCE: Clinicians could apply such evidence to optimise pain management and judgement about treatment efficacy, and researches may find it useful when designing their investigations.

A split-mouth randomized clinical trial was carried out to assess the effectiveness of sealants in preventing carious ICDAS (International Caries Detection and Assessment System) 3-6 lesions within a 2-year follow-up. We evaluated the effectiveness of 2 types of resin-based sealants, with and without fluoride, their retention rates, and the caries risk factors related to their outcomes. The study included 663 tooth pairs in 400 children (aged 5-15 years) considered to be at high individual caries risk (ICR) and presenting permanent molars free of caries or affected by ICDAS 1-2 lesions. In the first randomization, molars were either randomized to the treatment group receiving a dental sealant or the control group (nontreatment), and in the second randomization the sealant material to be used in the intervention group was selected. Uni- and multivariate Cox proportional hazard models were employed. At the 2-year follow-up, 483 tooth pairs were assessed: sealed molars had 83% (adjusted HR = 0.17; 95% CI: 0.15-0.20) less risk of developing ICDAS 3-6 lesions than molars without sealant. The magnitude of the protective effect was lower among teeth with ICDAS 1-2 lesions or with occlusal deep fissures than without. If the total retention rate of sealants was 70% at 2 years, sealant loss was not associated with the risk of caries (HR = 1.29, 95% CI: 0.92-1.79, p = 0.14). Sealants allow the prevention of new ICDAS 3-6 lesions or progression of noncavitated carious lesions in children at high ICR, and the effect of the sealant was similar regardless of whether it contained fluoride or not.

AIMS: To translate the Pictorial Representation of Illness and Self Measure (PRISM) instrument from German to Portuguese (Brazilian) and adapt it to the Brazilian cultural context, and then assess its reliability and validity in orofacial pain patients. METHODS: The PRISM was translated to Portuguese then back-translated to German. The translated PRISM was evaluated by a multidisciplinary committee and administered as a pre-test to 30 Portuguese-speaking orofacial pain patients. Psychometric properties were obtained after testing 116 orofacial pain patients. Validity was obtained through correlation analyses of scores obtained from PRISM and other psychometric tests, including the Numerical Pain Scale (NPS), Insomnia Severity Index (ISI), and Hospital Anxiety and Depression Scale (HAD). RESULTS: The adapted instrument showed high levels of reliability, proven by means of the test-retest procedure, and calculation of the Intraclass Correlation Coefficient (ICC = 0.991). Significant correlations were found between PRISM and the other tests. Correlation with NPS was moderate (-0.42), whereas correlations with ISI (-0.24), HAD-anxiety (-0.25), and HAD-depression (-0.22) were weak. CONCLUSION: The cross-cultural adaptation process of PRISM was successful and the adapted version offers reliable and valid psychometric properties in the Brazilian context.

This study tested a jaw support device for patients receiving dental care while suffering from temporomandibular joint pain. This crossover randomized trial used 31 subjects with jaw pain. Subjects underwent 2 consecutive dental scaling sessions of 30 minutes each. For each subject, the device was used for 1 of the sessions. Subjects completed questionnaires regarding jaw pain and jaw fatigue before and after each session. Multivariate analyses were performed to assess the device's effectiveness in preventing the aggravation of pain and fatigue during dental treatment. Statistically significant differences were found for jaw pain (P = 0.001), and fatigue (P = 0.04), indicating the effectiveness of the device. Based on the results, supporting the mandible of patients with temporomandibular disorders during dental treatments may prevent further pain.

This study aimed to evaluate the association of pain-related disability with biopsychosocial factors in temporomandibular disorders (TMD) patients. The study was carried out at the Orofacial Pain Outpatient Clinic of the State University of Feira de Santana, Bahia, from September 2018 to March 2020. The sociodemographic aspects, TMD subtypes, presence of pain-induced disability, pressure pain threshold, perceived stress, anxiety, depression, and catastrophizing were evaluated in 61 patients. The studied variables were compared between patients with and without pain-induced disability. Crude and adjusted logistic regression were performed to obtain estimates of odds ratios (OR) and 95% confidence intervals. With the exception of catastrophizing, there was no association between the biopsychosocial factors and pain-induced disability. The presence of catastrophizing increased the chance of having chronic pain-induced disability by 4.02 times. The results of this study indicate a strong association between pain catastrophizing and disability in individuals with chronic painful TMD.

AIMS: To document National Dental Practice-Based Research Network (PBRN) practitioner treatment recommendations for patients with painful temporomandibular disorders (TMDs) and to identify practitioner/practice- and patient-related factors contributing to treatment recommendations made at the initial clinical visit. METHODS: This prospective single-sample cohort study formed groups based on treatment recommendations made by 185 dental practitioners who treated 1,901 patients with painful TMDs. At the baseline visit, which this article describes, practitioners provided patients with their diagnoses and a treatment plan and then completed a comprehensive questionnaire. RESULTS: Self-care, an intraoral appliance, medication, and practitioner-recommended jaw exercises were the most frequently recommended treatments. Practitioners recommended multiple treatments to most patients. TMD signs, symptoms, and diagnoses were primary considerations in treatment planning, but the practitioner's expectations for improvement were only significant for intraoral appliances and self-care. Female practitioners and those with expertise in TMDs more frequently recommended patient-directed and multidisciplinary treatments compared to their counterparts. CONCLUSIONS: Practitioners used a wide range of treatments for patients with few consistent patterns. The propensity to use TMD signs, symptoms, and diagnoses when making treatment recommendations suggests a tendency to conceptualize patients using the biomedical model. Infrequent referral to nondental providers suggests a lack of availability of these providers, a misunderstanding of the complexity of TMDs, and/or discomfort with assessment of psychosocial factors. Implications include the need for comprehensive training in the assessment and management of TMD patients during dental school and participation in TMD continuing education courses following evidence-based guidelines.

OBJECTIVES: The aim of this study was to create and validate a drawing to help adults establish when to replace a manual toothbrush. METHODS: This cohort study had two phases. Phase I (3 months, 50 subjects) aimed to create a drawing of average wear in a toothbrush based on a wear index (WI) of 68% for the tested toothbrush. This was validated in Phase II (3 months, 30 participants). Pictures of worn brushing surfaces were generated using an image acquisition system. Images in each study phase were superimposed to provide a single reference outline to indicate when a toothbrush should be replaced. Residual plaque index values for identical brushing protocols were recorded using new and worn toothbrushes in Phase I and compared using Student's paired t-test. Student's t-test was used to compare duration of tooth-brushing and WI values in both phases. RESULTS: After brushing according to a uniform protocol, the residual plaque index at baseline was significantly lower than that at the last use of the toothbrush (P < 0.01). The drawings generated in Phases I and II were similar in terms of WI (P = 0.33) and period of use (P = 0.12). CONCLUSIONS: This simple drawing may help adults establish when they should replace a toothbrush.

Background: Temporomandibular disorders (TMDs) are common and cause persistent pain. Comorbidities are associated with TMDs and can affect the effectiveness of their treatments. The literature is lacking enough evidence on the difference between acute and chronic pain, particularly in TMDs. Investigating this difference could highlight potential risk factors for the transition from acute to chronic pain-related TMDs. Aim: To compare the likelihood of back and neck pain (BP, NP) between acute and chronic pain-related TMDs (AP-TMD, CP-TMD) as defined by pain duration and pain-related disability. . Methods: Participants with AP-TMDs (≤3 months) and CP-TMDs (>3 months) were recruited according to the diagnostic criteria and research diagnostic criteria of TMD. BP and NP were assessed using a self-reported checklist. CP-TMDs defined by disability (chronic disability) and depression and anxiety symptoms were assessed using validated instruments. Logistic regression analyses were employed. Results: This study enrolled 487 adults with AP-TMD (n = 118) and CP-TMD (n = 369). Relative to AP-TMD, participants with CP-TMD had twice the odds of reporting NP (odds ratio [OR] = 2.17 , 95% CI 1.27-3.71) but not BP (OR = 0.96, 95% CI 0.57-1.64). Participants with chronic disability were twice as likely to report NP (OR = 1.95 , 95% CI 1.20-3.17 ) but not BP (OR = 1.13, 95% CI 0.69-1.82) compared to those without. All analyses were adjusted for age, sex, and anxiety and depression symptoms. Conclusions: Within the limitations of this study, results suggest that central dysregulation or trigeminocervical convergence mechanisms are implicated in the process of pain-related TMD chronification and highlight the relevance of considering disability when defining CP-TMDs.
Contexte : Les troubles temporo-mandibulaires (TTM) sont fréquents et provoquent des douleurs persistantes. Des comorbidités sont associées aux TTM et peuvent affecter l'efficacité de leur traitement. Il n'y a pas suffisamment de données probantes dans la litt\érature sur la différence entre la douleur aiguë et la douleur chronique, en particulier dans les TTM. L'étude de cette différence pourrait mettre en évidence les facteurs de risque potentiels pour la transition des TTM liés à la douleur aiguë aux TTM liés à la douleur chronique.Objectif : Comparer la probabilité de douleur au dos et de douleur cervicale (DD, DC) entre les TTM liés à la douleur aiguë et les TTM liés à la douleur chronique (TTM-DA, TTM-DC), telles que définis par la durée de la douleur et l'incapacité liée à la douleur.Méthodes : Les participants atteints de TTM-DA (≤3 mois) et de TTM-DC (>3 mois) ont été recrutés selon les critères diagnostiques et les critères diagnostiques pour la recherche en matière de TTM. La douleur au dos et la douleur cervicale ont été évaluées à l'aide d'une liste de contrôle autodéclarée. Les TTM-DC définis par l'invalidité (invalidité chronique) et les symptômes de dépression et d'anxiété ont été évalués à l'aide d'instruments validés. Des analyses de régression logistique ont été utilisées.Résultats : Cette étude a inclus 487 adultes atteints de TTM-DA (n = 118) et de TTM-DC (n = 369). Comparativement aux patients atteints de TTM-DA, les participants atteints de TTM-DC étaient deux fois plus susceptibles de déclarer de la douleur cervicale (rapport de cotes [RC] = 2,17, IC à 95 % 1,27-3,71) mais pas de douleur au dos (RC = 0,96, IC à 95 % 0,57-1,64). Les participants ayant une incapacité chronique étaient deux fois plus susceptibles de déclarer de la douleur cervicale (RC = 1,95, IC à 95 % 1,20-3,17), mais pas de douleur au dos (RC = 1,13, IC à 95 % 0,69-1,82) que ceux n'en ayant pas. Toutes les analyses ont été ajustées en fonction de l'âge, du sexe, de l'anxiété et des symptômes de dépression.Conclusions : Dans les limites de cette étude, les résultats indiquent que la dysrégulation centrale ou les mécanismes de convergence trigéminocervicale sont impliqués dans le processus de chronicisation des TTM liés à la douleur et soulignent la pertinence de tenir compte de l'incapacité au moment de définir les TTM-DC.
RESUMEN
Although most cases of pain-related temporomandibular disorders (TMD) are mild and self-limiting, about 10% of TMD patients develop severe disorders associated with chronic pain and disability. It has been suggested that pain intensity contributes to the transition from acute to chronic pain-related TMD. Therefore, the aims of this current prospective cohort study were to assess if pain intensity, pain always being present, pain or stiffness on awakening, jaw activities, and interference, were associated with the transition from acute to chronic pain-related TMD at 3 months of follow-up. One hundred and nine participants, recruited from four clinics in Montreal and Ottawa, received examinations and completed the required instruments at baseline and at the 3rd month of follow-up. In a multivariable analysis including sex, age, characteristic pain index (CPI) (OR = 1.03, 95%CI = 1.01-1.06, P = 0.005), moderate to severe average pain intensity (OR = 3.51, 95%CI = 1.24-9.93, P = 0.02), disability points score (OR = 1.29, 95%CI = 1.06-1.57, P = 0.01), interferences (ORs = 1.30-1.32, P = 0.003-0.005), screening score (OR = 1.37, 95%CI = 1.08-1.76, P = 0.01), and pain always present (OR = 2.55, 95%CI = 1.08-6.00, P = 0.03) assessed at first-visit were related to the transition outcome at the 3rd month of follow-up. Further, we found that if 4 patients with acute pain-related TMD on average were exposed to these risk factors at baseline, 1 would have the transition from acute to chronic pain at 3 months of follow-up. Results indicate that these factors are associated with the transition from acute to chronic pain-related TMD, and therefore should be considered as important factors when evaluating and developing treatment plans for patients with pain-related TMD.
RESUMEN
BACKGROUND: Patients often seek consultation with dentists for temporomandibular disorders (TMDs). The objectives of this article were to describe the methods of a large prospective cohort study of painful TMD management, practitioners' and patients' characteristics, and practitioners' initial treatment recommendations conducted by The National Dental Practice-Based Research Network (the "network"). METHODS: Participating dentists recruited into this study treated patients seeking treatment for painful TMDs. The authors developed self-report instruments based on well-accepted instruments. The authors collected demographics, biopsychosocial characteristics, TMD symptoms, diagnoses, treatments, treatment adherence, and painful TMDs and jaw function outcomes through 6 months. RESULTS: Participating dentists were predominately White (76.8%) and male (62.2%), had a mean age of 52 years, and were general practitioners (73.5%) with 23.8% having completed an orofacial pain residency. Of the 1,901 patients with painful TMDs recruited, the predominant demographics were White (84.3%) and female (83.3%). Patients' mean age was 44 years, 88.8% self-reported good to excellent health, and 85.9% had education beyond high school. Eighty-two percent had pain or stiffness of the jaw on awakening, and 40.3% had low-intensity pain. The most frequent diagnoses were myalgia (72.4%) and headache attributed to TMDs (51.0%). Self-care instruction (89.4%), intraoral appliances (75.4%), and medications (57.6%) were recommended frequently. CONCLUSIONS: The characteristics of this TMD cohort include those typical of US patients with painful TMDs. Network practitioners typically managed TMDs using conservative treatments. PRACTICAL IMPLICATIONS: This study provides credible data regarding painful TMDs and TMD management provided by network practitioners across the United States. Knowledge acquired of treatment recommendations and patient reports may support future research and improve dental school curricula.

In this complex context of coronavirus disease 2019 (COVID-19), headache medicine has been completely affected by this new reality, with new types of headaches directly or indirectly related to COVID-19 being detected. Personal protective equipment (PPE) was recommended for workers in many professions that did not previously require wearing masks leading to new headaches, or the exacerbation of past headaches, especially among health workers. A 57-year-old female working in a secondary care hospital had a history of migraine twice/month without aura and allodynia symptom checklist (ASC12) scored as 7 before COVID-19 outbreak. She began to work with PPE (surgical masks, face shield and surgical cap) and migraines became daily (bifrontal, pulsatile, with photophobia, nausea, vomiting and of severe intensity, visual analog scale: 7), starting after 1 h of wearing protective equipment and lasted for at least 6 h during the day. There was no adequate response to treatment. The headache frequency retuned to twice/month after the patient stayed home 45 days due to another condition. It is hypothesized here that people with allodynia symptoms when exposed to PPE are more susceptible to the development of new headaches or to the worsening of existing primary headaches. The relationship between previous allodynia determined with the ASC12 questionnaire and new headaches, or past primary headaches that have become worse during the COVID-19 pandemic in workers using PPE, should be better investigated in order to clarify this hypothesis. Cutaneous allodynia could be related with the sensitivity to PPE and headache progression.
RESUMEN
Introduction: The search for an ideal biomarker for migraine has persisted for a long time. There is plentiful evidence of potential biomarkers for migraine found in cerebrospinal fluid, blood, and saliva.Areas covered: Herein, the authors highlight and discuss the most promising candidates in the literature. An electronic search was performed for studies published between 2010 and 2020 in MEDLINE, PubMed, and EMBASE, related to potential biomarkers in migraine patients, found in cerebrospinal fluid, saliva, and serum, focusing on biomarkers that can be related to treatment and clinical outcomes.Expert opinion: An ideal biomarker, or a panel of biomarkers, could revolutionize the way we address and propose treatments for this disease. Once severe presentations and phenotypes have been identified using a reliable biomarker, patients could be treated at earlier disease stages with more specific medications. The most important biomarkers with the most significant levels of evidence comprised calcitonin gene-related peptide (CGRP), glutamate, nerve growth factor, some inflammatory (CRP, TNF-α, interleukins) and oxidative stress markers. CGRP was associated with episodic, chronic migraine and response to treatment. Pituitary adenylate cyclase-activating polypeptide is an emerging neuropeptide involved in migraine diagnostics and severity. New genetic and epigenetic biomarkers will be candidates for future research.

The impact of comorbidities in fibromyalgia (FM) and temporomandibular disorders (TMD) have been well documented, but whether TMD sub-diagnoses myalgia (MYA) and myofascial pain with referral (MFP) differ regarding comorbidity is unclear. We aimed to elucidate this by studying the presence and associations of comorbidities in FM, MFP and MYA. An extended version of the Diagnostic Criteria for TMD axis II questionnaire was used to examine demographics, pain and comorbidities in 81 patients with FM, 80 with MYA, and 81 with MFP. Patients with MFP and FM reported a higher percentage of irritable bowel syndrome (IBS), depression, anxiety, somatic symptoms, perceived stress, and insomnia compared to MYA. Patients with FM had more IBS, depression, and somatic symptom disorder versus MFP. After adjusting for confounding variables, participants with anxiety, somatic symptoms disorder, pain catastrophizing, and perceived stress, as well as a greater number of comorbidities, were more likely to have MFP than MYA, whereas FM participants were more associated with IBS, somatic symptoms and insomnia compared to MFP. The number of comorbidities was significantly associated with widespread pain but not pain duration, body mass index or being on sick leave. In conclusion, patients with MFP were more similar to those with FM regarding comorbidity and should be differentiated from MYA in clinical settings and pain management.
