Self-correction of the ectopic eruption of the maxillary first permanent molar and its predictive factors: A systematic review.

Background: Ectopic eruption of the maxillary first permanent molar is a local disturbance that affects the development of the occlusion.

Aim: To evaluate the occurrence of self-correction of maxillary first permanent molar's ectopic eruption and its predictive factors.

Design: Five electronic databases and part of the gray literature were investigated.

Spontaneous changes in mandibular incisor crowding from mixed to permanent dentition: a systematic review.

Introduction: Dental crowding is the most prevalent malocclusion in the mixed and permanent detitions and can have a major impact on dentofacial esthetics. However, adjustments to the development and growth of the dentition can potentiate self-correction of dental crowding during childhood.

Objective: To evaluate the physiological behavior of mandibular incisor crowding in the transition from mixed to permanent dentition.

Orthodontic Retainers and the Stability of the Maxillary Arch in Unilateral Cleft lip and Palate Patients: A Systematic Review.

Objective: The aim of this systematic review was to elucidate the role of orthodontic retainers on the stability of compensatory orthodontic treatment in patients with unilateral cleft lip and palate.

Methods: Five electronic databases (PubMed, Scopus, Web of Science, LILACS, and LIVIVO) and the grey literature (OpenGrey and Google Scholar) were investigated, according to the population, exposure, comparator, outcomes and Study design eligibility criterion. The risk of bias assessment was determined based on the Risk of Bias In Nonrandomized Studies of Exposure (ROBINS-E) and the level of evidence with the GRADE tool.

Treatment stability with bonded versus vacuum-formed retainers: a systematic review of randomized clinical trials.

Background: In orthodontics, the retention phase can be considered challenging and unpredictable. Therefore, evidence obtained from different retention protocols is important to facilitate clinical decision-making.

Objectives: This systematic review aimed to compare the clinical effectiveness of bonded versus vacuum-formed retainers (VFRs) regarding their capacity to maintain treatment stability, periodontal effects, and failure rates.

What is the survival rate of deciduous molars in cases with agenesis of premolar successors? A systematic review.

Objectives: To systematically review the literature on the survival rate of deciduous molars in cases of agenesis of premolar successors.

Materials And Methods: Four electronic databases and partial grey literature were searched up to November 2020. The PECOS eligibility criteria included (P) second deciduous molar (E) exposed to agenesis of a premolar successor (O) evaluated by the survival rate in the oral cavity, infraocclusion, and root resorption through (S) observational studies.

Allergies/asthma and root resorption: a systematic review.

Background: This review synthesizes the available evidence about the predisposition of individuals with asthma or allergies to orthodontically induced inflammatory root resorption (OIIRR) and possible factors related to root resorption that were investigated in the included studies, such as the type of malocclusion, duration of orthodontic treatment, and tooth units.

Material And Methods: Six electronic databases and partial gray literature were searched without date or language restrictions until September 2020. Prospective and retrospective observational cohort and case-control studies were included.

Evaluation of root resorption following orthodontic intrusion: a systematic review and meta-analysis.

Background/objective: To quantify the expected amount of orthodontically induced root resorption (OIRR) after orthodontic intrusion and assess the treatment-related factors.

Search Methods And Eligibility Criteria: Six electronic databases and partial grey literature were searched without limitations regarding language or publication year until April 2020. Randomized clinical trials and non-randomized prospective and retrospective studies evaluating root resorption after orthodontic intrusion were included.

Effects of micro-osteoperforations performed with Propel system on tooth movement, pain/quality of life, anchorage loss, and root resorption: a systematic review and meta-analysis.

Background: The aim of this systematic review was to evaluate the effect of micro-osteoperforations (MOPs) performed with Propel and other mini-screws on the rate of tooth movement, pain/discomfort, periodontal health, anchorage loss, and root resorption in patients undergoing orthodontic retraction compared to a control group.

Materials And Methods: PubMed, Cochrane, Web of Science, LILACS, Google Scholar, Scopus, and OpenGrey were searched without restriction. A manual search was also carried out.

Intraoral contact mucositis induced by cinnamon-flavored chewing gum--a case report.

Contact mucositis is an inflammatory mucosal reaction caused by many agents. A case of a 53-year-old man with contact-type allergy in oral mucosa due to cinnamon chewing gum is presented. This condition should be considered in the differential diagnosis of nonspecific oral lesions.
