Comparison of the Conventional and Laser Etching on the Bonding of the Orthodontic Brackets: An Original Research.

Background: Acid etching enamel improves resin-enamel adhesion and adhesive characteristics, but has pros and cons. The effects of laser etching on the bonding of orthodontic brackets vary depending on the wavelength, power output, exposure duration, and energy delivered.

Materials And Methods: This study used a new 1064-nm diode laser to irradiate 30 freshly extracted human premolars.

Effect of sertraline in patients with newly diagnosed depression and type 2 diabetes mellitus or hypertension: An observational study from south India.

Background And Aims: Patients with either type II diabetes mellitus (T2DM) or hypertension (HTN) are more prone to develop depression when compared with the general population. Along with comorbid of either T2DM or HTN, treatment of depression may become an even bigger challenge. The present study aimed to observe the effect of sertraline in newly diagnosed depression patients with T2DM or HTN.

An adjustment in NiTi closed coil spring for an extended range of activation.

The Nickel Titanium (NiTi) closed coil springs serve as an efficient force delivery system in orthodontic space closure mechanics. The closed coil springs with the eyelets come in various lengths to broaden its force characteristics for an expedient space closure. However, at a certain point of time of progressive space closure, the coil spring can be expanded no further for an adequate force delivery.

Mushroom composite button for orthodontic use.

Composite buttons are a valuable adjunct in orthodontic treatment mechanics and provide an esthetic alternative to metal buttons. In particular, their use warrants application in lingual orthodontic therapy or in any minor tooth movement situations. This paper describes the step by step technique for the fabrication of a mushroom shaped composite button for clinical use.
