A Comparative Analysis of Enamel Surface Roughness Following Various Interproximal Reduction Techniques: An Examination Using Scanning Electron Microscopy and Atomic Force Microscopy.

Interproximal enamel reduction (IER) is a minimally invasive therapeutic procedure commonly used in orthodontics to address both functional and aesthetic issues. Its mechanical effects on enamel surfaces induce the formation of grooves, furrows, scratches, depressions, and valleys. The aim of this study was to assess the enamel surface roughness resulting after the application of currently available methods for interproximal reduction.

Statistical Study Concerning Extraction and Non-Extraction Methods in Orthodontic Treatments.

Introduction: The need to extract permanent teeth for the correction of dento-maxillary anomalies remains even today a controversy in orthodontic therapy. The purpose of this study was to assess the orthodontist's point of view on the extraction and non-extraction methods used in orthodontic treatments, regarding clinical experience.

Material And Methods: A de novo conceived questionnaire was elaborated by means of Google Forms and it comprised 22 questions regarding gender, age, different proprieties and aspects of both extraction and non-extraction methods and the percentage of treated patients who developed an increase in dental sensitivity and caries activity following the therapeutic stripping procedure.

Comparative Evaluation of Dental Enamel Microhardness Following Various Methods of Interproximal Reduction: A Vickers Hardness Tester Investigation.

Interproximal enamel reduction, also known as stripping, is a common orthodontic procedure that reduces the mesiodistal diameter of teeth, allowing for a balance of available space in dental arches. The aim of this study was to assess the enamel surface microhardness resulting from the application of currently available methods for interproximal reduction. Forty-two extracted human permanent teeth were divided into six different groups, each subjected to a therapeutic stripping procedure using various methods (i.

Comparative Evaluation of Two Bracket Systems' Bond Strength: Conventional and Self-Ligating.

Adhesion remains a key element in dentistry, whether approached in prosthetics, odontology, or orthodontics. It is a continuously researched aspect, as improved materials and adhesive methods keep emerging in the market. No orthodontic treatment can be effective without the proper adhesion strength of the bonded elements on the teeth.

Comparative Evaluation of Two Bracket Systems' Kinetic Friction: Conventional and Self-Ligating.

Friction is an intensely studied feature in orthodontics, as the sliding mechanics approach remains one of the most utilized techniques in current practice, and the question of whether self-ligating brackets produce less friction than conventional brackets still stands. The objective of this study was to compare a self-ligating system with different closing mechanisms and a conventional system with different ligating mechanisms regarding their frictional properties. Laboratory measurements were performed using an advanced materials testing machine generating tensile strength and load at maximum Load values, which were statistically analyzed and compared.
