PURPOSE The purpose of this study was to compare the width ratio of maxillary anterior teeth according to age in the Korean population and to evaluate the maxillary central incisor width-to-length (W/L) ratio, given differences in age and gender. MATERIALS AND METHODS Ninety-three Korean adults were divided into 3 groups (n = 31) by age. Group I was 20 - 39 years old, Group II was 40 - 59 yea...

This case report aimed to present the course of surgically combined comprehensive orthodontic treatment a male adult with cleft lip and palate, showing left alveolar cleft, lateral deviation major segment maxilla, palatal transposition incisor. Preoperatively, midline upper central incisors was shifted by 7.0 mm right, right incisor showed transposition, residual 6.5 mm. Segmental Le Fort I ost...

Traumatic injuries to an immature permanent tooth may result in cessation of dentin deposition and root maturation. Endodontic treatment is often complicated in premature tooth with an uncertain prognosis. This article describes successful treatment of two traumatized maxillary central incisors with complicated crown fracture three months after trauma. The radiographic examination showed immatu...

A 10-year old Egyptian male presented with a geminated upper right central incisor along with a fused and rotated upper left central incisor in cross bite. He also had severe crowding in the maxillary arch and a congenitally missing lower right first permanent premolar. Orthodontic treatment was carried out to align upper right and left central incisors, lateral incisors, and canines. Treatment...

This research used the spectroradiometer (Pritchard Model 1980 B) to measure the spectral radiance factors of women's maxillary anterior teeth. The following conclusions were reached: 1. The spectral distributions of the anterior teeth were all similar at the cervical, middle, and incisal areas respectively. Their spectral distributions ran in parallel at an almost equal distance, with the curv...

To assess management of non-syndromic dens evaginatus affecting permanent maxillary central incisor, we performed a systematic review and also present a case report. We searched PubMed via MEDLINE and the reference lists of included reports. Eligible studies were any type of clinical studies describing the management of non-syndromic dens evaginatus affecting the crown of a permanent maxillary ...

INTRODUCTION The aim of this work was to assess the periodontal support of a central upper incisor recovered through a surgical-orthodontic approach compared to the spontaneously erupted contralateral incisor. CASE PRESENTATION This case study describes an 8-year-old Caucasian female with an impacted upper right central incisor. Surgical-orthodontic treatment was performed to reset the impact...

INTRODUCTION The present study was designed to clarify whether the bilateral cooperation in the human periodontal-masseteric reflex (PMR) differs between central incisors and canines. METHODS Surface array electrodes were placed on the bilateral masseter muscles to simultaneously record the firing activities of single motor units from both sides in seven healthy adults. During light clenching...

Primary anterior teeth with proximal caries lesions can be restored with resin-based composite using a simplified bonding technique. This report describes Class III restoration of primary incisors in a preschooler, using a self-etching adhesive system and a modified-bonding procedure.
