Quantitative assessment of root resorption in TAD-aided anchorage with and without RAP: A CBCT study on en masse retraction cases.

Introduction: The purpose of this study was to evaluate the amount of root resorption with mini implant-aided anchorage, with and without inducing the regional acceleratory phenomenon (RAP) in en masse retraction cases using cone-beam computed tomography (CBCT).

Methods: Thirty patients requiring therapeutic extraction of all first premolars were included in the study and randomly divided into two groups of fifteen patients each (groups I and II). Patients of both groups underwent retraction using mini implants.

SIDS plane: A simple and innovative alternative to Frankfurt horizontal plane.

Aims And Objectives: To derive a new horizontal plane which can be a suitable alternative to Frankfurt horizontal plane (FH plane).

Materials And Methods: 200 pre-treatment lateral roentogenic cephalograms from patient records in the department of orthodontics and dentofacial orthopaedics were traced. The landmarks were identified and marked and the measurements were carried out.

Assessment and comparison of cranial base morphology in individuals with long face and short face.

Objectives: The objectives of the study was to assess and compare the cranial base morphology in long face and short face.

Methodology: The study comprises 64 individuals (32 in each group). Group I consists of individual's with long face and group II comprises individuals with short face.

Effect of ER, CR: YSGG laser debonding on enamel surface changes in stainless steel and ceramic brackets - An study.

Aim: The aim of this in-vitro study was to observe and analyze the various enamel surface changes that occur due to laser debonding of metal and ceramic brackets, done by means of Er, Cr:YSGG laser.

Materials And Methods: 90 extracted premolars were randomly allocated into one of six groups with 15 teeth each. The groups represent metal brackets (Groups A1, A2, A3) and ceramic brackets (Groups B1, B2, B3).
