Prevalence of temporomandibular joint dysfunction symptoms in children aged 7–12 years

Abstract

Relevance. The prevalence of dentoalveolar anomalies in children is reported to range from 40% to 81% in various studies. Symptoms of temporomandibular joint (TMJ) dysfunction are more frequently observed in children with distal and deep occlusion, as well as in school-aged children with physiological occlusion.

Objective: This study aimed to evaluate the prevalence of TMJ dysfunction symptoms and their association with malocclusion in children aged 7–12 years.

Materials and methods. A total of 420 children aged 7–12 years (192 boys and 228 girls) attending schools in Volgograd were examined to assess the presence of malocclusion and TMJ dysfunction symptoms.

Results. Signs of TMJ dysfunction were identified in 188 children, representing 44.8% ± 2.4% of the sample. The most common indicators of TMJ dysfunction in prepubertal children were mandibular head dislocation (31.5% ± 2.3%) and deviations in mandibular movement trajectory during maximum mouth opening (19.3% ± 1.9%). The prevalence of TMJ dysfunction was higher among girls. Mandibular head dislocation was the most frequent symptom observed in both boys and girls. Among children with dentoalveolar anomalies, TMJ dysfunction symptoms were present in 51.3% ± 3.1% of cases. Students with malocclusion had a significantly higher prevalence of TMJ dysfunction symptoms (t = 3.57, p < 0.05).

Conclusion. Temporomandibular joint dysfunction is a common condition among children aged 7–12 years, affecting 44.8% of the study population. It was identified in children with and without malocclusion. The high prevalence of TMJ dysfunction symptoms in younger school-aged children underscores the need for heightened awareness among specialists to detect early signs of TMJ dysfunction, ensuring timely intervention to prevent potential complications.
