OBJECTIVES To obtain maxillary anterior tooth dimension and proportion values for the Central Chinese population and to evaluate the existence of sexual dimorphism, any consistent relationships between the tooth ratios, and the presence of golden proportions. METHODS Tooth dimensions and proportions of six maxillary anterior teeth were recorded on gypsum casts obtained from 147 subjects (82 w...

Solitary median maxillary central incisor (SMMCI) coexists in 34%-65% of patients initially diagnosed with congenital nasal pyriform aperture stenosis. SMMCI, a genetic syndrome, warrants consideration for further screening because of its high prevalence of other diagnostic possibilities-specifically central defects, like nasal obstruction and hypothalamo-pituitary axis abnormalities. We report...

This teenage patient presents with pronounced esthetic and functional dental concerns. An anterior frontal view of the patient’s dentition shows virtually total facial blockage of the maxillary right central incisor creating mesial contact of the right lateral incisor with the left central incisor immediately lingual to the blocked out right central incisor. A similar severe misalignment takes ...

A case is presented in which primary hyperoxaluria and oxalosis in a 14-year-old Caucasian female were diagnosed. Generalized root resorption resulted in a remarkable mobility of her maxillary central and lateral incisors, although no bone loss was noted. The management of the patient's dental concerns in this rare heritable metabolic disorder consisted of removing the maxillary incisor teeth a...

The purpose of this paper was to present the surgical exposure and orthodontic treatment of an 11-year-old boy with horizontally impacted permanent maxillary central incisors associated with bilateral mesiodentes. Panaromic and upper anterior occlusal radiographs showed horizontally impacted maxillary central incisors, vertically impacted molariform mesiodens, and rotated mesiodens located at t...

This paper describes the clinical course of a pediatric patient developing cervical external root resorption (CERR). An 11-year old male patient had sustained dental trauma and was diagnosed with crown fracture affecting the incisal and middle thirds of the maxillary right permanent central incisor and the maxillary right permanent lateral incisor with pulp exposure and CERR after 24 months. Di...

The present case report describes the interdisciplinary management of a patient with increased overbite and overjet, Angle’s Class Ⅰ malocclusion, bilateral agenesis mandibular central incisors microdontia upper lateral incisors. 18-year-old female had convex profile, maxillary dentoalveolar protrusion mild spacing in anterior region. Therefore, treatment consisted fixed appliance therapy, foll...

The following is a report of a 16-year-old boy with history of pain in the maxillary left central incisor and in the maxillary sinus area. Radiographs showed a w e l l d e m a r c a t e d , u n i l o c u l a r m i x e d radiolucent-radiodense lesion.

Transposition is a dental anomaly manifested by a positional interchange of two permanent teeth. The maxillary permanent canine usually transposes with the first premolar and occasionally with the lateral incisor. These are mainly genetically governed and are treated orthodontically if complete segment of tooth is present; in case of missing teeth, participation of cosmetic dentist is must. The...
