Comparative analysis of slenderization methods and their impact on enamel surfaces using SEM: An in vitro study

TL;DR

This study compares different methods of removing enamel during orthodontic treatment and evaluates their effects on enamel surfaces using SEM.

Contribution

The novelty lies in comparing specific IPR techniques and their impact on enamel surfaces using SEM in an in vitro setting.

Findings

Different IPR methods produce varying effects on enamel surfaces.

SEM analysis reveals surface alterations caused by each IPR technique.

Abstract

Interproximal reduction (IPR) is an orthodontic technique that removes 0.3-0.5 mm of enamel from interproximal surfaces to create
space, typically for mild to moderate crowding. It helps reshape approximal contacts and address Bolton's discrepancy. Various methods,
including air rotor stripping, diamond-coated disks and abrasive strips, are used for IPR. This study compares three IPR techniques
Double-sided oscillating IPR strips, interproximal stripping burs and carborundum discs-by examining their effects on enamel surfaces
using scanning electron microscopy (SEM).
