Abstract
BACKGROUND: It is probed for a long time about the cause and effect relationship between muscles and malocclusion. By the identification of role of muscle, there would be a holistic approach to diagnosis and a stable orthodontic treatment. Jaw depressor muscle is a less traversed area, which is dealt with in this study. The relation between anteroposterior mandibular dysplasia and depressors of the mandible forms the basis of the study. AIM AND OBJECTIVES: To compare the force interplay in maximum mouth opening in female subjects with anteroposterior mandibular dysplasia. MATERIALS AND METHODS: This study was carried out using 90 untreated samples who reported to Department of Orthodontics and Dentofacial Orthopaedics, Tamilnadu Government Dental College and Hospital. They were divided into three groups. GROUP I: 30 female patients with class I malocclusion with normal maxilla and normal mandible who fulfil the inclusion criteria with maximum overjet 2-4mm. GROUP II: 30 female patients with class II malocclusion with normal maxilla and retrognathic mandible who fulfil the inclusion criteria. GROUP III: 30 female patients with class III malocclusion with normal maxilla and prognathic mandible who fulfil the inclusion criteria. RESULTS: There was a statistically significant difference in force levels found amongst the three groups of malocclusion. The p>0.5 between class I and class II indicated statistical insignificance between these two groups. There was a statistically significant difference in the force levels between class II and class III.There was a statistically significant difference in force level between class I and class III. CONCLUSION: Among the three groups, class III differed significantly from the other two groups in terms of mouth opening forces being at a higher level. This implies the difference in muscular pattern and a probable aetiology of role of muscles in malocclusion, keeping in mind the stability of orthodontic treatment in which muscles play the foremost vindication.
