“…However, the results from the present survey must be interpreted with caution due to the restricted group of subjects presenting open bite. Among different malocclusions, posterior cross‐bite is thought to have a strong impact on the correct functioning of the masticatory system . In accordance with the current findings, previous studies revealed an association between posterior cross‐bite and TMD signs and symptoms .…”

Background The prevalence of malocclusion, temporomandibular disorders (TMD) and oral parafunctions is highly debated in children population. Objectives To investigate the prevalence of malocclusion, self‐reported oral parafunctions and TMD‐pain in Italian schoolchildren and to assess the association between the examined factors. Methods A total of 700 children aged 9‐11 years were selected among six public schools in Campania region (Italy). Molar relationship, overjet, overbite and cross‐bite were assessed through a clinical examination. Furthermore, the subjects were demanded to fill in a validated questionnaire for TMD‐pain screening and the short form of the Oral Behaviours Checklist. Descriptive statistics were used to report the frequencies. The associations between occlusal traits, oral parafunctions and TMD‐pain were analysed with a Pearson chi‐square test, as expressed by odds ratio and 95% confidence intervals. The significance level was set at P < 0.05. Results Molar Class I was the most frequently encountered molar relationship, followed by molar Class II, subdivision and molar Class III. Increased overjet was more common than negative overjet. Posterior cross‐bite was observed in 12% of children. TMD‐pain was recorded in 14.7% of subjects. High frequency of oral parafunctions was reported in 21.3% of subjects. A significant association was found between TMD‐pain and negative overbite. Cross‐bite and high frequency of oral parafunctions were associated with TMD‐pain. Conclusion The current results show that malocclusion, self‐reported oral parafunctions and TMD‐pain are frequent findings among Italian schoolchildren and that some occlusal factors and high frequency of oral parafunctions might be associated with TMD‐pain.

“…However, it must be stressed that a correct diagnosis of posterior cross‐bite was performed in the first investigation , because the sample was recruited directly in the secondary schools and underwent clinical examinations. Furthermore, the accuracy of self‐reported TMJ clicking assessed at baseline considering objective TMJ clicking as gold standard showed high specificity.…”

Among different malocclusions, posterior cross-bite is thought to have a strong impact on the correct functioning of the masticatory system. The association between unilateral posterior cross-bite (UPCB) and temporomandibular joint (TMJ) clicking, however, remains still controversial. The aim of this study was to investigate whether the presence of UCPB during early adolescence increases the risk of reporting TMJ clicking after a long-term follow-up. A longitudinal survey design was carried out in a group of 12-year-old young adolescents, who were examined at baseline for TMJ clicking sounds and unilateral posterior cross-bite. After 10 years, 519 subjects could be reached by a telephone survey. Standardised questions were used to collect self-reported TMJ sounds and to determine whether participants had received an orthodontic treatment. Logistic regression analysis revealed a significant association between unilateral posterior cross-bite and subjectively reported TMJ clicking (odds ratio = 6·0; 95% confidence limits = 3·4-10·8; P < 0·0001). The incidence of TMJ clicking was 12%. At a ten-year follow-up, self-reports of TMJ clicking were significantly associated with the presence of UPCB at baseline, but not with the report of having received an orthodontic treatment. Within the limitation of this study, the presence of unilateral posterior cross-bite in young adolescents may increase the risk of reporting TMJ sounds at a 10-year follow-up. The provision of an orthodontic treatment, however, does not appear to reduce the risk of reporting TMJ sounds.

“…Others have also found no associations or very weak associations between temporomandibular disorders and malocclusion traits. [13][14][15][16] There are only a few reports in the literature regarding the association between occlusal curvatures and the incidence of TMDs. The curves of Spee and Wilson are both of high significance in the establishment of a balanced and functional occlusion, 17,18 which provides bilateral, simultaneous, and equal contacts.…”

Objective: To identify differences in occlusal curvatures and maxillary arch dimensions between subjects with signs and symptoms of temporomandibular disorders (TMDs) and asymptomatic subjects. Materials and Methods: One hundred subjects (78 female and 22 male) who consented to participate in this research were examined for signs and symptoms of TMDs according to the guidelines of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC-TMD). In addition, occlusal measurements were performed for all subjects on plaster models. All statistical analyses were performed with SPSS (version 19). Results: Significant associations were revealed between the depth of the curve of Spee (COS) and temporomandibular joint (TMJ) sounds. Furthermore, maxillary arch width was negatively correlated to the steepness of the curve of Wilson. No differences were found between subjects with and without a history of orthodontic treatment. Conclusions: Subjects with TMJ sounds tend to have a flatter COS compared to subjects without TMJ sounds. (Angle Orthod. 2014;84:96-101.)
