In agreement with previous studies, the majority of supernumerary teeth were seen in the lower premolar region. That all patients with multiple supernumerary teeth were male and that most of these teeth were impacted was also in agreement with previous studies. The order of location frequency in previous studies has been premolar-molar-anterior; we found the order to be premolar-anterior with no supernumerary molar teeth observed. It was also interesting that no serious pathological findings were recorded.

Objective To determine the prevalence, types of teeth, and distribution of intracoronal resorption in permanent dentition in a large population. Methods A total of 9,570 panoramic radiographs were screened, and 2,922 unerupted teeth were examined. Results The 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. Conclusions Intracoronal 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.

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.

Digital panoramic images may have some diagnostic value for detecting CAAs and this early diagnosis could potentially increase the length and quality of life for people with CAAs.

Fanconi's anemia is an autosomal recessive disorder characterized by progressive pancytopenia and congenital malformation of the skeleton. This study investigated the oral health status of 15 children with Fanconi's anemia, including oral lesions, gingival and periodontal status, and dental abnormalities. All children in the group were found to have a tendency to develop tooth decay and were in need of dental treatment. Two had aggressive periodontitis. In one patient supernumerary teeth were found, while in another teeth were congenitally missing. The increased tendency toward periodontal disease in patients with Fanconi's anemia may be due not only to the anemia, leukopenia, and defective detoxification of oxygen radicals that are characteristic of the disease itself, but also to medications applied during intense immunosuppressive treatment, such as prednisolone.

Osteomas are benign, slow-growing osteogenic tumors commonly occurring in the craniofacial bones. Osteomas are characterized by the proliferation of compact and/or cancellous bone. It can be of a central, peripheral, or extraskeletal type. The peripheral type arises from the periosteum and is rarely seen in the mandible. The lingual surface and lower border of the body are the most common locations of these lesions. They are usually asymptomatic and can be discovered in routine clinical and radiographic examination. In this paper, we presented a large solitary peripheral osteoma located in the buccal surface of the left posterior mandible and causing facial deformity in a 37-year-old woman. Radiographic examination by computed tomography revealed radiopacity with a well-circumscribed, pedunculated mass approximately 3 cm in size. The osteoma was removed surgically, and no recurrence has been observed.

Purpose To investigate whether serum anti-müllerian hormone (AMH), follicle stimulating hormone (FSH), or antral follicle count (AFC) are predictive for clinical pregnancy in women who underwent IVF cycles at the age of 35 and older Methods A total of 240 consecutive women who underwent IVF cycles at the age of 35 and older were enrolled in this crsoss-sectional study. Pregnant and nonpregnant women were compared. Results The median AMH level of pregnant women was higher than non-pregnant women [3.20 (0.63-9.60) vs 1.15 (0.01-14.90) ng/ml, p<0.001]. On logistic regression analysis, AMH was an independent predictor of clinical pregnancy rate (CPR) (OR 1.353; 95 % CI 1.141-1.605; P<0.001). After controlling for the other independent variables (the number of retrieved oocytes, AFC and age), the significant association between AMH and clinical pregnancy rate remained strong (OR 1.677; 95 % CI 1.216-2.311; p=0.002) on multivariate logistic regression analysis. Conclusions AMH is an effective measure of quantitative ovarian reserve and it can predict ovarian response to controlled stimulation for advanced age women. The CPR tends to increase as AMH increases.
