Effect of CO Laser-Assisted Titanium Tetra-fluoride on Demineralization of Enamel Around Orthodontic Brackets.

One of the clinical problems following orthodontic treatment is white spot lesions around orthodontic brackets due to enamel demineralization. Confronting enamel demineralization during fixed treatments has long been a challenge for orthodontists. The aim of this in vitro study was to evaluate the effect of CO laser and Titanium Tetra-fluoride (TiF4) application on the prevention of enamel demineralization around orthodontic brackets.

Er,Cr:YSGG Laser as a Means of Orthodontic Adhesive Removal: Myth or Reality?

This study aimed to compare the effect of Er,Cr:YSGG laser with a tungsten carbide bur in orthodontic finishing on the enamel surface roughness and the heat generated in the pulp chamber. Before bonding, of 125 intact extracted premolar teeth, 15 teeth were randomly assigned to the control group. Of the remaining 110 bonded teeth, 50 were used to determine the laser parameters, and 60 were included in the main study.

Photogrammetric Comparison of Facial Soft Tissue Profile before and after Protraction Facemask Therapy in Class III Children (6-11 Years Old).

Statement Of The Problem: Achieving a normal soft tissue facial profile is considered to be the main concern of class III patients and the goal of most class III treatments.

Purpose: The purpose of this study was to investigate the effects of facemask treatment on profile with photogrammetric method.

Materials And Method: Before (T0) and after (T1) treatment photograms of 40 class III patients profiles (20 male and 20 female individuals) treated with protraction face mask that met the inclusion criteria were digitized and analyzed using Aesthetic Analyzer software.

The Effect of Four Surface Treatment Methods on the Shear Bond Strength of Metallic Brackets to the Fluorosed Enamel.

Statement Of The Problem: Some studies have reported the bond strength to be significantly lower in fluorotic enamels than the non-fluorosed.

Purpose: The purpose of this study was to evaluate the shear bond streongth of metallic brackets to non-fluorosed and fluorosed teeth after different enamel conditioning.

Materials And Method: A total of 176 freshly extracted human premolars (88 non-fluorosed and 88 fluorosed teeth) were used in this study for bonding the metallic brackets.

Photographic Facial Soft Tissue Analysis by Means of Linear and Angular Measurements in an Adolescent Persian Population.

To obtain objective average measurements of the profile and frontal facial soft tissue to be used as a guide for aesthetic treatment goals. Methods and Materials : This observational study included 110 females and 130 males high school students aged 16-18 years. None of the subjects had any facial deformities.

Utilization of Orthodontic Services in the Fars Province, Iran: The Reasons People Travel to the Capital for Orthodontic Treatment.

Statement Of The Problem: The first step towards appropriately planning orthodontic treatment and prevention services is to understand the needs and demands of the target population. However, this is ignored in most developing countries.

Purpose: This study aims to evaluate the attitudes of patients in Fars province towards travelling to the provincial capital (Shiraz) to receive orthodontic treatments.

The public attitude towards selecting dental health centers.

Statement Of The Problem: No published literature was found studying the people's reasons on why to choose or not to choose a dental care setting in south Iran, while understanding their attitude towards choosing their dental care center is consequential for planning a successful oral health care service system.   

Purpose: To determine the factors affecting how people of the city of Shiraz choose their dental health services.

Materials And Method: A cross-sectional analytic study was designed.

Tooth eruption sequence and dental crowding: a case-control study.

Unlabelled: When cases of dental crowding are identified and diagnosed promptly, interceptive orthodontics is particularly successful.

Aim: To assess the differences in the eruption sequence of the mandibular canine and first premolar teeth in children with and without dental crowding.

Materials And Methods: Children who attended the Shiraz Dental School's orthodontic clinic (Iran) from September to December 2012 were enrolled in this case-control study.
