Results: The mean GI was significantly higher in males (1.56 ± 0.31 mm) when compared to females (1.42 ± 0.34 mm). Hence the present sample was subjected to discriminant analysis with gender as a grouping variable, GI and GA as independent variables. Based on Wilk’s lambda values Gonial index (GI) was observed to provide better sex determination when compared to Gonial angle (GA). Hence 2 diffe...

Aim: The aim of the study was to determine the extent of genetic influence and environmental contribution to craniofacial growth and development. Materials and methods: A total of 15 pairs of twins were selected and divided into monozygotic (8) and dizygotic (7) with the help of DNA fingerprinting. Lateral cephalograms were taken. Linear measurements—anterior cranial base, posterior cranial bas...

BACKGROUND The aim of this study is to identify cephalometric pretreatment parameters for prediction of Class II improvement induced by rapid maxillary expansion. METHODS Lateral cephalograms of 30 patients (mean age 8.3 ± 1.6 years old) showing Class II molar relationship and undergone to rapid maxillary expansion on the upper deciduous molars were traced before treatment, and molar relation...

Background Impacted third molars may be responsible for various problems within the oral cavity. Impaction may be due to inadequate space or varied angulations. Assessment of variables contributing for impaction may influence the fate of impacted third molars. MethodologyRetrospective analysis of panoramic radiographs of adolescents in Indian population subpopulation was done to evaluate angula...

It was the aim of this study to investigate radiologically the distraction site in the gonial angle area after three different protocols of unidirectional mandibular distraction in sheep. Bilateral mandibular distraction was performed in nine sheep, and one other sheep served as a sham-operated control. In the nine experimental sheep, three different distraction protocols were used. In three sh...

OBJECTIVES The aim of this study was to verify the concordance of the measurement values when the same cephalometric analysis method was used for two-dimensional (2D) cephalometric radiography and three-dimensional computed tomography (3D CT), and to identify which 3D Frankfort horizontal (FH) plane was the most concordant with FH plane used for cephalometric radiography. MATERIALS AND METHOD...

We measured the gonial angle (GA) on panoramic radiography (PR) and analyzed the correlation between the GA on PR and lateral cephalometric radiography (LCR). In total, 49 PR films and LCR films from dentate young adults were evaluated. Orthodontists plotted four points (articulare, menton, posterior gonion, and lower gonion) on the PR and carefully traced them. Using a protractor, two radiolog...
