Prevalence of craniomandibular disorders in orthodontic pediatric population and possible interactions with anxiety and stress

Abstract

AIM: To analyse the presence and prevalence of gnathologic problems in a sample of children, candidate for orthodontic treatment, and evaluate the relationship between psychological factors and gnathological problems. The purpose of this study was also to evaluate a simple protocol with specific psychological test and a questionnaire for the rapid diagnosis of gnathologic problems, useful for possible screening studies on a wider population. MATERIALS: Study Design: Observational, cross-sectional study. Among the patients coming for a first orthodontic evaluation 106 children, aged between 8 and 16 years, were examined. A complete orthodontic evaluation was performed in all patients; the RCMAS (Revised Children's Manifest Anxiety Scale) was used in the study to test the psychological condition, while the selected test for the diagnosis of gnathologic problems was the Fonseca Test. The prevalence of temporomandibular disorders (TMD) was evaluated with descriptive statistical analysis, and the eventually present correlation with a positive psycological test for anxiety has been evaluated with correlation parameters: c2 test of Pearson, and Cramer's V index. CONCLUSION: The protocol largely respected the need for speed of administration, comprehensiveness and reliability that we set out to achieve. Limited correlations have been assessed between occlusal conditions and positivity to the administrated tests. Further studies are desirable to increase the sample population.
