AIMS: To determine whether patients with painful myofascial temporomandibular disorders (TMD) demonstrate facilitated temporal summation (TS) responses to painful heat stimuli applied to the painful trigeminal and extratrigeminal regions and whether there is a side difference in the trigeminal region for myofascial TMD pain patients compared to healthy controls. METHODS: Twenty female Chinese myofascial TMD pain patients and 20 age-matched female volunteers participated in this case-control study...

AIMS: To deepen knowledge of the impact of iatrogenic trigeminal nerve injury on dental patients. METHODS: One-to-one semi-structured interviews and workshops were conducted with 12 patients who had incurred a nerve injury from dental treatment. Nerve injury was diagnosed by oral surgeons via a series of neurosensory tests. Interpretive phenomenologic analysis was used to analyze the narratives from the interviews.

AIMS: To investigate how photographic images (Pain Cards) co-created by an artist and chronic pain patients could be used in groups of patients with burning mouth syndrome to facilitate characterization of their pain and its impact on quality of life. METHODS: Ten groups of patients with burning mouth syndrome attending a 2.5-hour information session in a facial pain unit were presented with 54 Pain Cards put in a random order on a table. They were asked to pick one card that described the quality of their pain and one that reflected the impact of the pain on their lives...

Trigeminal autonomic cephalalgias (TAC) are primary headache disorders that are characterized by severe unilateral pain along the distribution of the trigeminal nerve with corresponding activation of the autonomic nervous system. The clinical characteristics and presentation of TAC are unique; however, there may be an overlap of these features with other painful conditions affecting the orofacial region, which can be a diagnostic challenge for the clinician. This article reports a case history and discusses the differences between clinical characteristics of TAC and other painful orofacial conditions...

AIMS: To evaluate the risk of hepatotoxicity due to unintentional paracetamol misuse in patients with acute dental pain. METHODS: A prospective multicenter observational survey was performed in patients consulting, without appointment, the odontology departments of three main French hospitals in the Lorraine region over a 3-month period. Patients were asked to fill out a medical questionnaire while seated in the waiting room. Those who completed the questionnaire, had dental pain, and took paracetamol were included in the DAntaLor study...

AIMS: To investigate the objective and subjective characteristics of sleep and psychosomatic and physiologic variables in young subjects with different frequencies of rhythmic masticatory muscle activity (RMMA) during sleep. METHODS: A total of 54 young (mean age 23.8 ± 2.1 years), healthy subjects underwent polysomnographic (PSG) recordings for 2 nights. Sleep and psychosomatic states were assessed prior to PSG using validated questionnaires, and the following PSG variables were assessed before and after sleep: subjective sleep quality, physical symptoms, anxiety level, and salivary biomarkers...

Trigeminal autonomic cephalalgias (TACs) are primary headaches that include cluster headache (CH), paroxysmal hemicrania (PH), and short-lasting unilateral neuralgiform headache attacks (SUNHAs) with conjunctival injection and tearing (SUNCT) or cranial autonomic features (SUNA). Hemicrania continua (HC) is another form that has been ascribed to TACs for clinical and pathophysiologic reasons. Cluster headache is the most common of these syndromes, even if comparatively rare, with a lifetime prevalence of around 1 in 1,000...

AIMS: To compare the impacts of trigeminal neuralgia (TN) and painful posttraumatic trigeminal neuropathy (PPTTN) on psychologic function and health-related quality of life (HRQoL) using a comprehensive quantitative assessment. METHODS: This was a comparative cross-sectional study. A total of 97 patients diagnosed with PPTTN and 40 patients diagnosed with TN who sought treatment at an orofacial pain clinic completed standardized self-report measures of pain intensity, neuropathic symptoms, pain self-efficacy, mood, and indicators of general and oral HRQoL...

AIMS: To determine the prevalence of sleep bruxism (SB) in adult obstructive sleep apnea (OSA) patients, to assess the association between SB and OSA in terms of sleep macrostructure and respiratory parameters, and to determine possible OSA risk factors for SB. METHODS: Type I polysomnographic data of 147 adult OSA patients (mean age 44.6 ± 12.8 years) were evaluated for SB. SB episodes were scored when masseter rhythmic masticatory muscle activity (RMMA) was twice the background electromyography amplitude, and SB was established when patients had more than four SB episodes per hour of sleep...

AIMS: To test whether standardized palpation around the lateral pole of the condyle can influence mechanical sensitivity and unpleasantness and evoke referred sensations/pain in healthy individuals. METHODS: Palpometers (0.5, 1.0, and 2.0 kg) with spherical extensions were applied around the lateral pole of the condyle in relaxed and protruded positions of the mandible for 2, 5, and 10 seconds in 30 healthy participants. Mechanical sensitivity, unpleasantness, and referred sensations/pain were assessed using a 0 to 100 numeric rating scale (NRS) for each palpation...

AIMS: To (1) examine differences in self-rated health (SRH) between a group of women with myofascial temporomandibular disorders (mTMD) and controls; (2) determine the extent to which pain, mental health, and physical function mediate these differences; and (3) explore specific mTMD symptoms and impairments explaining SRH among mTMD cases. METHODS: An existing dataset of a sample of women with mTMD (n = 125) and a group of demographically similar controls (n = 49) was used...

AIMS: To assess jaw pain shortly after whiplash trauma in relation to neck pain, physical symptoms, depression, and jaw pain-related disability. METHODS: A total of 181 cases (106 women and 75 men, mean ages 33.7 and 36.8 years, respectively) were examined within 1 month after a whiplash trauma and compared to 117 controls (68 women and 49 men, 34.2 and 30.9 years, respectively). Participants rated current jaw and neck pain intensity on a numeric rating scale and rated nonspecific physical symptoms and depression symptoms on subscales of the Symptom Checklist-90-Revised...

AIMS: To investigate the occurrence, associations, and impacts of self-reported nocturnal parafunction, daytime parafunction, temporomandibular joint (TMJ) pain, and TMJ clicking in a New Zealand birth cohort of 38-year-old individuals. METHODS: A cross-sectional analysis of data from a longstanding prospective observational study of a Dunedin, New Zealand birth cohort was undertaken. A questionnaire was used to measure self-reported nocturnal parafunction, daytime parafunction, TMJ pain, and TMJ clicking, and the short-form Oral Health Impact Profile (OHIP-14) tool was used to measure the impacts of these factors while controlling for personality traits...

AIMS: To assess the validity of the resting and chewing components of the recently developed observational diagnostic tool, the Orofacial Pain Scale for Non-Verbal Individuals (OPS-NVI). METHODS: This cross-sectional observational study was carried out in two UK hospitals. A total of 56 participants with dementia who were admitted to the acute hospital were observed for 3 minutes during rest and during chewing, and the OPS-NVI was used to identify orofacial pain...

AIMS: To investigate the relationships between three pain parameters (duration, intensity, and frequency), the number of pain sites and comorbidities, and the risk of having coexisting pain and/or comorbidities in patients with temporomandibular disorder (TMD) pain. METHODS: The sample consisted of 198 outpatients attending the Dental Hospital of Chulalongkorn University. TMD pain was determined using the Diagnostic Criteria for TMD. Pain lasting 3 months or longer was defined as chronic pain...

AIMS: To investigate whether acute dental pain due to pulpal or periapical inflammation is associated with increased expression of cortisol and inflammatory markers and mediators in the saliva, as well as changes in salivary flow rate. METHODS: Patients experiencing pain (n = 42) were recruited when seeking emergency dental treatment. A 0 to 10 numeric rating scale (NRS) was used as a measure of the severity of pain, and the number of days with pain sensation was also recorded...
