Anxiety and depression in keratotic oral lichen planus: a multicentric study from the SIPMO.

OBJECTIVES: Oral lichen planus with exclusive keratotic reticular, papular, and/or plaque-like lesions (K-OLP) is a clinical pattern of OLP that may be associated with a complex symptomatology and psychological alteration. The aim of the study was to evaluate the prevalence of anxiety (A) and depression (D) in patients with K-OLP, analyzing the potential predictors which can affect mental health status. METHODS: Three hundred K-OLP patients versus 300 healthy controls (HC) were recruited in 15 Italian universities. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), and Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A) were administered. RESULTS: The K-OLP patients showed statistically higher scores in the NRS, T-PRI, HAM-D, and HAM-A compared with the HC (p-value < 0.001**). A and D were found in 158 (52.7%) and 148 (49.3%) K-OLP patients. Strong linear correlations were identified between HAM-A, HAM-D, NRS, T-PRI, and employment status and between HAM-D, HAM-A, NRS, T-PRI, employment status, and female gender. Multivariate logistic regression revealed that HAM-D and HAM-A showed the greatest increase in the R2 value for A and D in the K-OLP patients, respectively (DR2 = 55.5% p-value < 0.001**; DR2 = 56.5% p-value < 0.001**). CONCLUSIONS: The prevalence of A and D is higher in the K-OLP patients compared with the HC, also found in K-OLP subjects without pain, suggesting that the processing of pain may be in a certain way independent of the processing of mood. CLINICAL RELEVANCE: Mood disorders and pain assessment should be carefully performed in relation to K-OLP to obtain a complete analysis of the patients.

Pediatric temporomandibular joint ankylosis and arthritis: Forgotten complications of acute otitis media.

OBJECTIVES: Temporomandibular joint (TMJ) arthritis and ankylosis represent unusual but potential complications of ear suppuration, especially in children. We performed a review of the literature of pediatric otogenic TMJ arthritis and ankylosis, discussing their clinical and radiological features, their mechanism of infection spread, and the importance of a prompt diagnosis and treatment. We additionally describe a case of TMJ ankylosis following acute mastoiditis in a 4-year-old female patient. METHODS: A search of English literature from January 1, 1980 to December 31, 2021 was performed on the electronic databases (PubMed, Web of Science and Scopus) in order to identify studies concerning TMJ complication after ear suppuration. RESULTS: Seventeen articles were considered eligible for the review. Eight and nine studies described otogenic TMJ ankylosis and arthritis, respectively. A total of 17 children affected by ankylosis consequent to ear infection and a total of 31 cases of TMJ arthritis concurrent to otomastoiditis were identified. Mean time elapsed between ear infection and diagnosis of TMJ ankylosis was 4.8 years (range 0.5-13). CONCLUSION: TMJ involvement during complicated otitis media should be kept in mind. Its prompt recognition is mandatory to set up appropriate treatment and follow-up and reduce the risk of ankylosis with its functional and psychological complications.

Orthodontics is temporomandibular disorder-neutral.

OBJECTIVES: To assess if subjects with a clinical diagnosis of temporomandibular disorders (TMDs) have a similar prevalence of orthodontic history as a population of TMD-free individuals and to assess if those subjects who have a history of ideal orthodontics have fewer symptoms than those with a history of nonideal orthodontics. MATERIALS AND METHODS: Two groups of age- and sex-matched individuals belonging to either a study ("TMD") or a control group were recruited. Subjects who underwent orthodontic treatment were classified as having a history of ideal or nonideal orthodontics based on the current presence of normal values in five reference occlusal features. RESULTS: The correlation with a history of orthodontic treatment was not clinically significant for any of the TMD diagnoses (ie, muscle pain, joint pain, disc displacement, arthrosis), with Phi (Φ) coefficient values within the -0.120 to 0.058 range. Within the subset of patients with a history of orthodontics, the correlation of ideal or nonideal orthodontic treatment with TMD diagnoses was, in general, not clinically relevant or was weakly relevant. CONCLUSIONS: Findings confirmed the substantial absence of clinically significant effects of orthodontics as far as TMD is concerned. The very low correlation values of a negative or positive history of ideal or nonideal orthodontics with the different TMD diagnoses suggest that orthodontic treatment could not have a true role for TMD.

The diagnostic process for temporomandibular disorders.

The diagnostic process for temporomandibular disorders (TMD) is complicated by the multifactorial etiology and multiplicity of clinical signs and symptoms characterizing such disorders. Several electronic instruments and radiological techniques have been proposed over the years in the attempt to integrate clinical evaluation of TMD patients. Nonetheless, literature data still suggest that TMD diagnosis should be based on a thorough clinical assessment and international classifying scheme, also rely on standardized clinical tests to categorize TMD patients. Imaging techniques should be used to gain a better insight within the temporomandibular joint, reserving magnetic resonance to the depiction of soft tissues and computerized tomography to bone structures. EMG-based devices failed to prove effective in improving the diagnostic process for TMD, since a lack of correlation between instrumental signs and patients' symptoms has been showed. The TMD diagnostic process also relies on a psychosocial assessment of patients, which can be useful to detect a psychosocial impairment that needs to be addressed at the therapeutical level.
