The aim of this study was to investigate the facial profile changes of patients treated with and without extractions of four first premolars using novel computer-based digital subtraction software. The pre- and post-treatment radiographic image pairs of 25 extraction (13 girls and 12 boys, mean age = 12.64 +/- 1.82 years) and 24 non-extraction (12 girls and 12 boys, mean age = 12.48 +/- 1.66 ye...

CLINICAL PRESENTATION A 22-year-old white female presented with a solitary, well circumscribed, round radiolucency 15 mm in diameter, with a largely sclerotic border in the mandibular midline, seen on Panorex (Fig 1) and occlusal films. The lesion was asymptomatic and of unknown duration, and there was no detectable expansion of the jaw. The incisor teeth were nonrestored, noncarious, and vital...

The treatment of skeletal and dental Class III malocclusions is a challenge for orthodontists, one the alternatives non-growing patient orthodontic camouflage treatment. Different approaches may result in different outcomes; therefore, proper diagnosis plan are needed to avoid undesirable effects. In this case, 21-year-old female presented with malocclusion, normal maxilla, prognathic mandible,...

A finite element model is used to explore the stress-strain responses of the mandibular central incisor and its associated periodontal ligament (PDL) while opening the bite. The finite element model consisted of the mandibular teeth, the alveolar bone, and the PDL of the mandibular incisors. The clinical scenario was simulated by applying a force of 10 cN to the mandibular incisor in a crown-ro...

Background: This study aimed to assess the effect of tooth shape ratio on mandibular incisor arrangement. Materials and methods: The sample included dental casts of some dental students and orthodontic patients having Class I dental and skeletal patterns with normal occlusion and severe crowding. The sample was divided into two groups according to the severity of crowding into: group I had Clas...

This article reports the case of a Brazilian child diagnosed with Kabuki make-up syndrome (KMS), addressing the clinical features observed, with emphasis on the disease-specific oral and craniofacial manifestations. The patient had the distinctive KMS craniofacial appearance, mild delayed mental development, fingers with prominent fingertip pads and visual deficit. The dental findings included ...

Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. The cause of dens invaginatus is still unknown and controversial. Some hypotheses suggested by authors are: local external forces, apical proliferation of ameloblast or local retardation, arresting of development and focal developmental stimuli. Th...

OBJECTIVE The purpose of this study was to evaluate, by means of cephalometric appraisal, the vertical effects of non-extraction treatment of adult anterior open bite with clear aligners (Invisalign system, Align Technology, Santa Clara, CA, USA). METHODS Lateral cephalograms of 30 adult patients with anterior open bite treated using Invisalign (22 females, 8 males; mean age at start of treat...

This manuscript describes the treatment of a 27-year-old patient who was previously treated with two maxillary first premolar extractions. The patient had skeletal Class III malocclusion, Class III canine relationship, anterior crossbite, and a concave profile. As the patient refused orthognathic surgery, a miniplate was used on the right side of the lower arch as an anchorage unit after the ex...
