Cephalometric appraisal of tongue and related soft tissues in normal and open bite subjects at rest.

Aim: To compare the tongue position of normal and open bite subjects at rest and to study if there is any difference in the hyoid bone and posterior pharyngeal wall positions in normal and open bite subjects.

Materials And Methods: Sample size consisted of 48 individuals with 24 subjects having normal occlusion and 24 subjects having open bite malocclusion within the age range of 16 to 25 y. Standardized Lateral cephalograms were taken for all the subjects.

Comparison of landmark identification and linear and angular measurements in conventional and digital cephalometry.

The purpose was to compare the reliability of landmark identification and linear and angular measurements in conventional versus digital cephalometry. Using 50 cephalometric radiographs, four orthodontic residents identified 19 cephalometric landmarks followed by 18 linear and angular measurements of the same radiographs. The values of 18 measurements were compared to quantify the measurement difference and interobserver errors between these two methods.

Effect of the gingival display on posed smile with different facial forms: a comparison of dentists and patients concepts.

Aim: The aim of this study was to evaluate and compare the importance of amount of gingival display on smile esthetics and facial attractiveness in males and females with different facial forms by orthodontists as well as lay person.

Materials And Methods: Frontal photographs of 18 male and female patients (9 male and 9 female) each, at a posed smile, seeking treatment in the Department of Orthodontics and Dentofacial Orthopedics were obtained. The photographs were divided in 3 groups based on their facial forms (Short face, Average face and Long face) and were altered by moving the dentition within the lip frame of the captured photograph to bring about different gingival display at smile.
