Objective. The purpose of the present study was to assess the symphyseal morphology and lower incisor angulation in different anteroposterior relationship and in different growth patterns and to investigate whether the symphyseal morphology had any correlation with dentofacial parameters. Method. Random Sampling method and lateral cephalograms of 90 subjects, age group 16-30 years, were divided into 30 in each group, i.e. Class I, Class II & Class III after calculating the following parameters (ANB angle, wits appraisal). After that, groups were again divided into 10 in each subgroup i.e. Average, Horizontal and Vertical growers. Results. Results showed the increase in actual symphysis width, inclination of the alveolar part, total height of symphysis and reduction in overall width along with retroclination of lower incisors in class III subjects as compared to class I and class II. Similarly actual and overall width of the symphysis were decreased and inclination of the alveolar part, symphyseal height and symphyseal ratio were increased in vertical growers. Conclusion. The dimensions and configuration of Mandibular Symphysis in class III was found to be different than those in Class I and Class II relationships; the alveolar part of Mandibular Symphyseal compensated for the skeletal relationship in the Class III pattern. Mandibualr Symphysis dimensions were strongly correlated to anterior facial dimensions. Similarly the dimensions and configuration of Mandibular Symphysis was also different in vertical growers as compared to horizontal and average growers, moreover symphyseal morphology and lower incisor angulation had a correlation with dentofacial parameters.

Aims: To determine association between lip print pattern and different skeletal malocclusions and gender: Material and Methods: Lip prints of 250 patients were obtained and analyzed. Skeletal and dental class I, II, III were analyzed and gender were mentioned. Kruskal wallis test was applied and p value was derived. Level of significance was kept at .05%. Results: In skeletal Class I Males, type IV lip print is common; while in class I females IV are most common. In skeletal Class II males, Type IV. However in Class II females-Lip print type II is most common. In skeletal class III males Type I lip print is more common and class III Females Type II lip print is commonest. Conclusion: There exists a particular pattern of Lip prints in certain skeletal malocclusion and gender. Aims and objectives: To analyze the association of different lip print patterns in different skeletal malocclusion and gender and derive a relation between the two.
