Can shielded brackets reduce mucosa alteration and increase comfort perception in orthodontic patients in the first 3 days of treatment? A single-blind randomized controlled trial.

Introduction: Orthodontic patients can experience pain and discomfort on the oral mucosa from trauma caused by friction with the brackets and the wires. In this split-mouth design, single-blind randomized controlled trial, we aimed to investigate whether brackets with a self-snapping customized plastic shield would induce less mucosa alteration and discomfort than those without the shield.

Methods: The overall sample comprised 42 patients (22 female, 20 male) from a government-funded orthodontic practice, with a mean age of 16.

Association between tooth size and interarch relationships in children with operated complete unilateral cleft lip and palate.

Background: To evaluate mesiodistal tooth width of patients with UCLP comparing tooth size in different Goslon Yardstick scores and between cleft and noncleft sides.

Methods: The Department of Orthodontics at Bauru Dental School and Hospital of Rehabilitation of Craniofacial Anomalies - University of Sao Paulo. Hundred forty-four pairs of dental casts of patients with UCLP.

Immediate periodontal bone plate changes induced by rapid maxillary expansion in the early mixed dentition: CT findings.

Objective: This study aimed at evaluating buccal and lingual bone plate changes caused by rapid maxillary expansion (RME) in the mixed dentition by means of computed tomography (CT).

Methods: The sample comprised spiral CT exams taken from 22 mixed dentition patients from 6 to 9 years of age (mean age of 8.1 years) presenting constricted maxillary arch treated with Haas-type expanders.

Comparison of friction produced by two types of orthodontic bracket protectors.

Introduction: Fixed orthodontic appliances have been regarded as a common causative factor of oral lesions. To manage soft tissue discomfort, most orthodontists recommend using a small amount of utility wax over the brackets in order to alleviate trauma. This in vitro study aimed at evaluating friction generated by two types of bracket protectors (customized acetate protector [CAP] and temporary resin protector [TRP]) during the initial stages of orthodontic treatment.

Complications of misdiagnosis of maxillary canine ectopic eruption.

Ectopic eruption of maxillary canines can be associated with root resorption of adjacent teeth. This case report describes and discusses an interesting case of a 15-year-old girl with a Class III malocclusion and an impacted maxillary canine. Because of the unfavorable position of the ectopic canine and the severe root resorption of the maxillary left central and lateral incisors, the treatment options included extraction of the maxillary permanent canines.

Orthodontic movement of a maxillary incisor through the midpalatal suture: a case report.

Orthodontic space closure is a treatment alternative when a maxillary central incisor is missing. The objective of this report was to present an unusual treatment in which a right maxillary central incisor was moved through the midpalatal suture to replace the absent contralateral tooth. The biologic aspects and clinical appearance of the recontoured lateral and central incisors were analyzed.
