A Comparative Evaluation of Enamel Surface Roughness of Two Different Bonding Adhesives After Debonding With Atomic Force Microscopy.

Introduction The debonding procedures should restore the enamel surface to its pre-treatment state as much as possible after removing orthodontic attachments and all remaining adhesive remnants from the surface of the tooth. The orthodontic attachments are bonded commonly by a light-cured composite system. Light-cured glass ionomer cement has been developed as an alternative to the composite as a bonding agent for orthodontic brackets.

A Cephalometric Evaluation of Sexual Dimorphism of the Angle Sella-Nasion-Frankfort Horizontal Plane in Different Sagittal Classes of Malocclusion in South Indian Population.

Aims And Objectives: The present study aims to evaluate the gender dimorphism of the angle SN-FH between the sella-nasion (SN) plane and the Frankfort horizontal (FH) plane among the three types of skeletal malocclusion in South Indian population. The objectives included measurement of angle SN-FH, FH to the nasion (NFH), FH to the sella (SFH), and the difference of NFH and SFH (Δ). The null hypothesis was that there exists no variation of the angle SN-FH, NFH, SFH, and Δ between males and females and in the different skeletal relationship of jaws.
