Supernumerary teeth which occur both in the primary and the permanent dentition are seen more frequently in the permanent dentition causing a variety of pathological disturbances. Presented herewith is a case report of a patient with a mesiodens which had caused flaring of the maxillary central incisors and impeded normal eruption of the maxillary lateral incisors. Extraction of the mesiodens w...

Oligodontia is agenesis of numerous teeth (> 6), excluding the third molars. Its prevalence in permanent teeth has been estimated to be 0.14%. It is one of the most common anomaly affecting the permanent dentition but equally infrequent in the primary dentition. Presented here is a case report of 7 year old child with congenitally missing 10 primary anteriors in both maxillary and mandibular de...

Gemination is defined as an attempt to make two teeth from one enamel organ. Bilateral presentation of this phenomenon is very rare, with prevalence of 0.01% to 0.04% in the primary, and 0.05% in the permanent dentition. This paper describes a rare case of huge bilateral gemination of permanent maxillary central incisors in a nine-year-old Iranian boy with poor aesthetic. The patient did not ha...

We performed measurement using a 3-dimensional measurement system in study models of children with anterior crossbite in the primary dentition treated using a chin cap and lingual arch, and evaluated changes in the dentition and occlusion after treatment based on measurement values and also using wire frame models. Comparing with the situation before treatment, the overbite of anterior teeth sh...

The term anterior open bite, which means no contact between anterior teeth, stands out in current orthodontic by the complexity of the treatment, associated with high levels of instability and recurrence. The purpose of this study is to emphasize that early etiological diagnosis is essential to the successful outcome of the technical intervention. The bibliographical study shows that, once the ...

The talon cusp is a relatively rare dental developmental anomaly characterized by cusp-like projections, usually observed on the lingual surface of the affected tooth. Normal enamel covers the cusp and fuses with the lingual aspect of the tooth. The cusp may or may not contain an extension of the pulp. The condition can occur in both the primary and permanent dentitions. However, the occurrence...

extensive breakdown of primary teeth to the cervical level and their loss in very young children is not uncommon. owing to increasing concerns over self-appearance, due considerations to esthetic aspects in addition to restoring function are necessary aspects of rehabilitation of mutilated teeth to help children grow into a psychologically balanced personality. the present article describes reh...
