Evaluation of skeletal and dental age using third molar calcification, condylar height and length of the mandibular body.

Aim: To identify the most reliable method for age estimation among three variables, that is, condylar height, length of mandibular body and third molar calcification by Demirjian's method.

Materials And Methods: Orthopantomograms and lateral cephalograms of 60 patients with equal gender ratio were included in the study, among each gender 15 subjects were below 18 years and 15 subjects were above 18 years. Lateral cephalograms were traced, height of condyle and mandibular body are measured manually on the tracing paper, OPG's were observed on radiographic illuminator and maturity score of third molar calcification was noted according to Demirjian's method.

Correlation of masseter muscle thickness and intermolar width - an ultrasonography study.

Background: To determine the association between the thickness of masseter muscle and the maxillary dental arch width. To explore the influence of gender on masseter muscle thickness.

Materials & Methods: Seventy subjects (35 females and 35 males) of age 18 to 25 years were selected for the study based on class I molar relationship.

A comparative study of linear measurements on facial skeleton with frontal and lateral cephalogram.

Objective: To compare the accuracy of linear measurements on lateral and frontal cephalograms with gold standard skull measurements.

Materials And Methods: Based on the specific criteria including reliable occlusion and condyles fitting in glenoid fossa, 15 dry human skulls were selected from a larger collection. Lateral and frontal cephalograms were taken of each skull by standardized methods.
