No full textThe Relation Between Daytime Sleepiness and Awake and Sleep Bruxism Report in Patients With Obstructive Sleep Apnoea
Full text linkObjective: To assess the relationship between daytime sleepiness and both self‐reported awake bruxism (AB) and sleep bruxism (SB) in patients with different severities of obstructive sleep apnoea (OSA). Material and Methods: One hundred and seventy‐four participants (female = 33.9%; mean age [±SD] = 55.1 ± 12.3 years) with polygraphy‐confirmed OSA underwent a self‐reported assessment for both awake and SB and daytime sleepiness, using the BRUX scale questionnaire and Epworth sleepiness scale, respectively. Three BRUX scale sum scores were computed for each patient: total sum score, AB sum score and SB sum score. To assess OSA severity, the apnoea‐hypopnoea index and minimal oxygen saturation (MinSat) were considered. Correlations between daytime sleepiness, BRUX scale scores and OSA severity were assessed using Pearson's test. In addition, a multiple linear regression analysis model was used to assess the predictive effect of both self‐reported awake and SB and OSA severity on daytime sleepiness. Results: A significant, but weak correlation emerged between daytime sleepiness and the BRUX scale total sum score ( r = 0.155; p < 0.05), the awake BRUX scale sum score ( r = 0.174; p < 0.05) and MinSat ( r = 0.194; p < 0.01). No significant correlations were found between OSA severity and any other variables. The multiple linear regression analysis showed that only the awake BRUX scale sum score had a positive predictive association with daytime sleepiness ( B = 0.485; [95% CI = 0.076; 0.936]; p = 0.027). Conclusions: Within the limitations of this study, in individuals with OSA, self‐reported AB showed a predictive effect for daytime sleepiness, while no significant correlation between daytime sleepiness and OSA severity emerged
Two-needle vs. single-needle technique for TMJ arthrocentesis plus hyaluronic acid injections: a comparative trial over a six-month follow up.
No full textThe aim of the study was to compare the effectiveness of five weekly two-needle arthrocentesis plus hyaluronic injections vs. the same protocol performed with a single-needle technique in patients with inflammatory-degenerative disorders of the temporomandibular joint (TMJ). 80 patients with TMJ osteoarthritis were randomly assigned to the two-needle or single-needle protocol and followed up for 6 months after treatment. Several outcome parameters, such as maximum pain at rest and maximum pain on chewing, subjective chewing efficiency, limitation in jaw function, jaw range of motion in mm, were recorded at baseline and multiple follow up assessments. Both treatment groups recorded significant improvement with respect to baseline levels in almost all outcome variables. The rate of improvement was not significantly different between the treatment protocols in any of the outcome variables (p-values between 0.143 and 0.970). No between-group differences emerged for the perceived subjective efficacy (p = 0.321) and the treatment tolerability (p = 0.783). The present investigation did not support the existence of significant differences in the treatment effectiveness for inflammatory-degenerative TMJ disorders of a cycle of five weekly injections of arthrocentesis plus hyaluronic acid injections performed according to the classical two-needle or the single-needle techniqu
Interrelationship between temporomandibular joint osteoarthritis (OA) and cervical spine pain: Effects of intra-articular injection with hyaluronic acid
No full textOBJECTIVE:
The aim of this study was to evaluate cervical spine pain and function after five sessions of viscosupplementation with hyaluronic acid (HA) in patients with temporomandibular joint (TMJ) osteoarthritis.
METHODS:
Forty-nine patients, (79% females, aged between 43-81 years), affected by TMJ osteoarthritis and concurrent cervical spine pain and limited function were recruited. All patients underwent a cycle of five weekly arthrocenteses and viscosupplementation with 1 ml of medium molecular weight HA according to the single-needle arthrocentesis technique. Outcome variables were TMJ pain (VAS), cervical active ranges of motion, cervical disability (NPDS), and presence of painful palpation sites. Assessments were carried out at baseline and at one, three and six months after the end of treatment protocol.
RESULTS:
A significant reduction over time was shown both in TMJ pain levels and in NPDS values with respect to baseline (p < 0.001). Most parameters of active cervical range of motion showed an improvement with time. Benefits remained stable throughout six months after the viscosupplementation protocol.
CONCLUSIONS:
A protocol of TMJ intra articular arthrocentesis and viscosupplementation improved cervical function and reduced disability in patients with concurrent cervical spine pain. These findings add to the complex amount of literature on the relationship between temporomandibular disorders and cervical spine disorders
Personality traits are potentially associated with the presence of chronic temporomandibular joint pain in patients without effusion as determined by T-2 weighted magnetic resonance
No full textThe study aimed at investigating personality traits in chronic temporomandibular joints (TMJ) pain patients with and without joint effusion. METHODS:
Two groups of chronic TMJ pain patients were recruited. The TMJ pain control group was composed of patients showing magnetic resonance imaging (MRI) signs of TMJ effusion, while the TMJ pain test group included patients with chronic TMJ pain seemingly not justified, due to the absence of MRI-detected disorders. A third set of pain free individuals was selected as a comparison group. All patients completed a personality assessment with the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) instrument, and the between-group differences were assessed for significance by performing an analysis of variance test.
RESULTS:
Patients of the TMJ pain test group had higher scores than subjects belonging to the TMJ pain and pain-free control groups in almost all of the MMPI-2 clinical scales. A significant difference was shown for the scales related to concerns about physical health (Scale 1-Hs; F = 7.74; p = .001) and physical symptoms (Scale 3-Hy; F = 8.43; p = .001).
CONCLUSIONS:
Chronic TMJ pain patients without MRI-detected TMJ effusion have a different personality profile than patients with TMJ effusion and pain-free individuals, regarding high levels of concerns about physical health and physical symptoms.
CLINICAL IMPLICATIONS:
This study has important clinical implications for temporomandibular disorders practitioners, providing suggestions that symptoms in the TMJ area are not only related to a physical disorder. The possible existence of a psychologically modulated condition in patients who refer pain in the TMJ area without signs of effusion should be carefully taken into consideration

Temporomandibular joint disorders in patients with different facial morphology. a systematic review of the literature
No full textPurpose The present article aimed to review systematically the literature on the relation between facial skeletal structures and temporomandibular joint (TMJ) disorders. Materials and Methods A systematic search in the dental and medical literature was performed to identify all studies of humans assessing the relation between TMJ disorders and facial morphology. Articles were included based on study design, irrespective of TMJ disorder (eg, disc displacement, osteoarthrosis, or unspecified), skeletal features, diagnostic strategies (eg, imaging techniques or clinical assessment), and population (eg, demographic features of participants) under investigation. The selected articles were assessed according to a format based on patients, problem, and population, intervention, comparison, and outcome and quality was evaluated based on the Newcastle-Ottawa Scale. Results Thirty-four articles were included in the review, 27 of which concerned adult samples and 7 concerned adolescent samples. Quality was generally moderate. The articles dealt with the relation between facial morphology and the following TMJ disorders, assessed clinically or by magnetic resonance (MR): disc displacement (n = 20), osteoarthritis or osteoarthrosis (n = 8), and temporomandibular disorder signs and symptoms (n = 6). The different approaches featuring the various investigations and the presence of some potential methodologic biases complicated a summary of the findings. Most studies reported that some features related to the vertical dimension of the face might help distinguish patients with potential TMJ disc displacement or MR-detected signs of osteoarthrosis from those without TMJ disorders. Conclusions The quality of the available literature is not adequate to provide an evidence base on the topic. Despite the heterogeneity of design and findings of the reviewed articles, it seems reasonable to suggest that skeletal Class II profiles and hyperdivergent growth patterns are likely associated with an increased frequency of TMJ disc displacement and degenerative disorders
