Mandibular Second Molar Protostylid: A Rare Case Report

Congenital missing or absence of 6 or less teeth is known as Hypodontia which is a usual part of more complex set of developmental problems. Most cases of tooth agenesis involve hypodontia. In reference to second premolar, agenesis of a single second premolar is the most common form and occurrence of agenesis of four second premolars in both maxilla and mandible is not a very common condition.The purpose of this report is to describe a case of agenesis of a four second premolars in all the four quadrants in a 17 year old boy.Patient referred to the pediatric dentistry department as achief complaint of pain in the left lower back tooth region since one week. Clinical examination revealed the retained four primary second molars in both the arches of right and left sides and orthopantamograph confirmed the diagnosis. Pulpectomy was performed in maxillary left as well as mandibular left and right pimary molars and maxillary right second molar was grossly decayed which was extracted. In addition to case report, this article discusses possible etiological factors along with various treatment modalities.Journal of Biomedical Sciences 2015;2(2):12-16

Mandibular Second Molar

A supernumerary tooth is an entity in addition to the normal series of teeth that, although rare, can be fused to a tooth, whether deciduous or permanent. Diagnosis and management in cases involving supernumerary teeth in the anterior region of the maxilla are often challenging. The clinical examination associated with the radiographic examination is decisive for the diagnosis and planning of cases. This article describes a case of unilateral fusion of a supernumerary tooth to a permanent upper lateral incisor, in which clinical and radiographic diagnosis was essential for a conservative approach.

Rare Case Report

Benign cementoblastoma is a rare ectomesenchymal odontogenic tumor that originates from the root of the tooth and that is characterized by the formation of cementum-like tissue. A 60-year old man was referred to us complaining of pain in his right jaw. The patient underwent TC dental scan of the mandible, which highlighted the presence of three well-circumscribed, round, unilocular neoformations of radiopaque appearance with a radiotransparent edge, one of which was in close contact with the roots of the lower right second molar. Microscopic examination of the greater sample consisted, in its central portion, of dense mineralized acellular trabeculae of basophilic tissue cement-like, devoid of vessels, adhering to the root of the tooth, while peripherally was observed a zone of vascularized osteoid surrounded, occasionally, by a thin rim of cementoblasts mixed with fibrous tissue and inflammatory elements. This lesion was diagnosed as cementoblastoma. The second lesion appeared radiologically and histologically entirely identical to cementoblastoma, but it did not show the intimate association with the root of involved tooth. After a careful review of the literature, the diagnosis of residual cementoblastoma was made. The clinicopathologic features, treatment, and prognosis of this rare tumor are here discussed for the young dental practitioner.
