Association between molar-incisor hypomineralisation and dental anomalies.

Background: Common etiological factors have been reported in the development of molar-incisor hypomineralisation (MIH) and dental anomalies (DA).

Aim: To assess the association between MIH and DAs.

Design: A cross-sectional study was performed to evaluate the presence of MIH and other six DAs in a sample of 415 pretreatment records from patients aged 9-18 years.

Why orthodontists need to know about molar incisor hypomineralization.

Molar incisor hypomineralization (MIH) is a systemic developmental qualitative defect of the enamel that affects 1-4 first permanent molars with or without incisor involvement. Enamel hypomineralization is identified visually as a demarcated opacity with a clear border with varying extensions and can be white, yellow, or brown. This opacity is characterized by a reduced quality of enamel that is of normal thickness but not fully mineralized.

American Board of Orthodontics (ABO) Discrepancy Index and peer assessment rating (PAR) index with models versus photographs.

Background: The objectives of this study were to determine whether rating systems, such as the Peer Assessment Rating (PAR) and the American Board of Orthodontics Objective Grading System (ABO-OGS) can be applied to intraoral photographs.

Methods: Models and photographs of 50 cases were graded by 4 raters, and a 20% repeat of randomized cases was completed 2 weeks later. Intraclass correlation coefficients (ICCs) were used to assess inter- and intra-rater agreements, as well as the level of agreement between the ratings on models and photographs.

The 100 most-cited articles in orthodontic journals in the last 20 years.

Introduction: This study aimed to identify and analyze the 100 most-cited articles published in orthodontic scientific journals in the past 21 years.

Methods: The research was conducted in the Thomson Reuters Web of Science data citation index, considering articles from 2000 to 2020 and the category of dentistry, oral surgery, and medicine. Information about the number of citations, citations per year, title, authors, year of publication, the title of scientific journals, type of study, keywords, and thematic field were extracted for each article.

Comparison of early and conventional autogenous secondary alveolar bone graft in children with cleft lip and palate: A systematic review.

Purpose: The literature is scarce on studies comparing secondary alveolar bone graft (SABG) performed early at approximately 5-6 years and at the conventional time at 9-11 years. This systematic literature review(SLR) aimed to compare clinical outcomes after two different timings of SABG in children with unilateral and bilateral cleft lip and palate.

Methods: The inclusion criteria were autogenous iliac grafts and the following study designs: case control, cohort, clinical controlled trial (CCT), randomized CCT (RCCT), and previous SLRs.
