During osteogenesis, mesenchymal tissues function to form fibrous matrix which changes into bone by ossification. In rare instances, fibrous matrix persists in which foci of immature bone is evident resulting in progressive enlargement. Such conditions are commonly benign in nature but few are anatomically benign and clinically destructive. Though recurrence and residual defects following surgi...

Dentigerous cysts form from accumulation of fluid between reduced enamel epithelium and the crown of an unerupted tooth. They cause several difficulties such as swelling, non-eruption of the involved teeth, and displacement of adjacent teeth, and thus require early detection and prompt treatment. Treatment ranges from marsupialisation to enucleation. Enucleation is rarely used in children compa...

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...

BACKGROUND Many reports have indicated the treatment for permanent teeth with disturbed eruption due to the presence of supernumerary teeth. However, successful treatment for an unerupted maxillary incisor with severe rotation and another maxillary incisor with disturbed eruption by a supernumerary tooth is quite rare. CASE REPORT We treated a 7-year-old Japanese male with an unerupted and se...

BACKGROUND Older subjects usually show less of their upper incisors and more of their lower incisors than younger subjects. OBJECTIVES To determine how much of the upper and lower central incisor crowns are visible in Brazilian subjects with their lips at rest. METHODS The subjects were 240 white Brazilian subjects divided into four age groups: Group 1, 12 to 15 years of age; Group 2, 20 to...

this is a case of delayed replantation of avulsed maxillary central incisor after an extended dry extra-alveolar period. a 10-year-old boy presented with avulsed maxillary central incisor after a fall that resulted in dental trauma, occurring 18 hours earlier. treatment guidelines for avulsed mature permanent teeth with prolonged extraoral time were carried out for the teeth and the extraoral e...

the purpose of this report is to present a rare case of a fused mandibular lateral incisor with supernumerary tooth with a follow-up for 18-months. a 35-year-old female patient was referred to our clinic with an extraoral sinus tract in the chin. the intraoral diagnosis revealed the fusion of her mandibular lateral incisors. vitality pulp tests were negative for mandibular right central and lat...

Molar-incisor malformation (MIM) or molar root-incisor (MRIM) is a dental anomaly that affects teeth and maxillary central incisors. Even though, the etiology not exactly known, it has been reported several factors such as staphylococcal infection in neonatal period, neurological diseases meningitis hydrocephalus, ongoing medications, infectious premature delivery were effective. In this case r...

Mechanical trauma or developmental disorders can cause an eruptive problem mostly called dilaceration. The prognosis of a dilacerated tooth depends on early diagnosis and appropriate treatment planning. The case presented in this paper is an example of severe dilacerations of a maxillary central incisor which has been treated with early orthodontic intervention.
