An evaluation of dentofacial changes in Angle's class II division 1 patients using AdvanSync 2.

Objectives: The purpose of the study is as follows: To evaluate the dental and skeletal changes of the AdvanSync 2 appliance.To evaluate the soft tissue changes of the AdvanSync 2 appliance using photometric analysis.

Methods: The sample size consisted of 15 patients who reported to the Department of Orthodontics, seeking fixed orthodontic treatment.

Comparative assessment of changes in pharyngeal airway space in cases of obstructive sleep apnoea with a customized mandibular repositioning appliance - a clinical study.

Objectives: The present study aims at evaluating the effects of a customized mandibular repositioning appliance on the pharyngeal airway, nocturnal sleep patterns, daytime discomfort and occlusal changes in established cases of adult obstructive sleep apnoea.

Material And Methods: Ten consecutive patients with a complaint of snoring and disturbed sleep were included in the study. The primary diagnosis was established by the Epworth sleepiness scale, clinical examination, history and subsequently the diagnosis was substantiated through assessment of the pharyngeal airway space on a lateral cephalogram and polysomnography.

A Comparative Evaluation of Interleukin 1 Beta and Prostaglandin E2 with and without Low-level Laser Therapy during Retraction.

Background And Objectives: Orthodontic forces are known to produce mechanical damage and inflammatory mediators such as prostaglandins (PGs) and interleukin (IL)-1, in the periodontium and dental pulp. Low-level laser therapy (LLLT) is a stimulator of the on-going biological process in tissue and found to be effective in modulating cell activity, which is involved in orthodontic tooth movement. Here, a humble effort has been made to study two such cytokines, namely IL-1 β and PG E2 (PGE2) which are partially responsible for bone turnover.

A Comparison of the Rate of Retraction with Low-level Laser Therapy and Conventional Retraction Technique.

Background And Objectives: A major concern of orthodontic patients is treatment time. Reducing the treatment time requires increasing the rate of orthodontic tooth movement. Research has proved that bone resorption is the rate-limiting step in tooth movement.
