Separation effect, pain perception during functional activity and gingival inflammation of elastomeric and Kansal separators-a split mouth study.

Introduction: An effective space opening for band placement with minimal pain and gingival inflammation is a prime requisite during fixed orthodontic procedures. The study aimed to compare the effectiveness of two types of separators, elastomeric and Kansal, in the amount of space opening, pain perception elicited, and gingival inflammation.

Methods: A random split-mouth study was designed with 30 subjects undergoing fixed orthodontic treatment.

Sagittal Positional Changes of the Mandible Following Alignment and Levelling of Class II Division 2 Cases: An Observational Study in Decelerating Stages of Adolescent Growth Spurt.

Introduction The objective of this observational study is to compare the dental and skeletal changes that occur following the release of incisor locking in class II division 2 patients in the decelerating phase of the adolescent growth spurt. Materials and methods Lateral cephalograms of 17 subjects with skeletal class II and division 2 malocclusion, taken at the pre-treatment (T1) and post-leveling and alignment (T2) phases, were analyzed. All these patients were treated with non-extraction methods in the initial stage.
