An unusual case of talon cusp on a geminated tooth

Talon cusp is a developmental anomaly seen on the lingual surface of anterior teeth. Gemination is an anomaly caused by a single tooth germ that attempted to divide during its development. These developmental anomalies may cause clinical problems including esthetic impairment, pain, caries and tooth crowding. This paper presents an unusual case of gemination accompanied by talon cusp in permanent dentition. The clinical and radiographic findings are described.

Prevalence and distribution of odontogenic and nonodontogenic cysts in a Turkish population

Objective: To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. Study Design A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayıs University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and histopathology reports from 2000 to 2008; a total of 12,350 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging patterns and pathologies associated with cystic lesions were also determined. Results: The prevalence of odontogenic and nonodontogenic cysts was 3.51%; males were affected more frequently than females. There were 452 odontogenic cysts (98.5%) and seven nonodontogenic cysts (1.5%). The most frequent odontogenic cyst was radicular (54.7%), followed by dentigerous (26.6%), residual (13.7%), odontogenic keratocyst (3.3%), and lateral periodontal cyst (0.2%). Nasopalatine duct cyst (1.5%) was the only nonodontogenic cyst. By age, cysts peaked in the third decade (24.2%). Concerning location, no statistically significant difference was found between the maxilla and mandible (p>0.05). The most frequent radiological feature of these lesions was unilocular cyst (93.7%). Pathologies associated with cystic lesions occurred in 14.7%. Conclusion: The prevalence of both odontogenic and nonodontogenic cysts were lower than that reported in many other studies. In our study population, cysts were mainly inflammatory in origin. Key words: Prevalence, odontogenic, nonodontogenic, cysts.

Prevalence and characteristics of intracoronal resorption in unerupted teeth in the permanent dentition: a retrospective study

ObjectiveTo determine the prevalence, types of teeth, and distribution of intracoronal resorption in permanent dentition in a large population.MethodsA total of 9,570 panoramic radiographs were screened, and 2,922 unerupted teeth were examined.ResultsThe prevalence of intracoronal dentine defects was 1.55% in subjects and 0.95% in teeth. The highest prevalence of intracoronal radiolucencies was noted in the mandibular second molar (9.5%), followed by the maxillary second premolar tooth (4.7%). To our knowledge, this is the first report of coronal radiolucency in maxillary supernumerary teeth. Of the lesions identified, 39.3% were two-thirds of the dentine thickness, and 21.4% included the enamel; 85.7% of the defects were located at the central aspect of the crown. Ectopically positioned teeth showing intracoronal resorption accounted for 14.3% of the cases.ConclusionsIntracoronal resorption in an unerupted tooth occurs frequently and can be seen in more than one tooth in an individual. This condition is usually associated with not only an ectopic position but also resorption, which may be a progressive process. Dental clinicians should conduct periodic follow-ups, both clinical and radiographic, of these unerupted teeth.

Benign cementoblastoma of the anterior mandible: an unusual case report

A benign cementoblastoma, which is another name for a true cementoma, is a rare neoplasm that develops from odontogenic ectomesenchyme. It is characterized by a mineralized mass attached to the apex of the root produced by neoplastic cementoblasts. More than 75% of cases arise in the mandible, with 90% of them manifesting in the molar and premolar regions. This neoplasm occurs most commonly in children and young adults, with males being affected slightly more than females. Radiographically, the tumor is observed as a well-defined radiopaque mass that is fused to a tooth root and is surrounded by a radiolucent rim. The treatment of benign cementoblastoma consists of removal of the lesion and extraction of the affected tooth. This report presents an unusual case of benign cementoblastoma in a 31-year-old female, presenting as a densely mineralized mass seen at the apex of the impacted right mandibular canine tooth on radiographs.

An unusual case of large, destructive stafne bone cavity with computed tomography findings

Stafne bone cavity (SBC) is an asymptomatic lingual bone depression that usually described as a small oval homogenous radiolucency in the posterior mandibular region. The radiographic appearance and location of the SBC are characteristic and easily identified. The diagnosis can be confirmed by computed tomography (CT) scans, magnetic resonance (MR) imaging or sialography. This report describes a case of SBC in a 61-year-old male asymptomatic patient, presenting as a radiolucency in the left mandibular body with loss of buccal and lingual cortical plates on three-dimensional CT scan.

Unilateral Aplasia of the Submandibular Gland with Multiple Calcified Cervical Lymph Nodes: A Case Report and Review of the Litarutre

The congenital absence of major salivary glands and nodal calcifications are both extremely rare disorders. We discuss a 67-year-old female patient with unilateral aplasia of the right submandibular gland and hypoplasia of the left submadibular gland, and the simultaneous presence of multiple calcified lymph nodes that were incidentally detected by panoramic radiography and computed tomography.
