Evaluation of sella turcica shape and dimensions in cleft subjects using cone-beam computed tomography

Objective: The aim of this study was to assess the morphology of the sella turcica and measure its size in cleft and non-cleft subjects

Material and Methods: Cone-beam computed tomography [CBCT] images of 54 individuals [29 males; 25 females] with cleft and 85 [22 males; 63 females] without cleft were used for this study. Syndromic patients with cleft [s] were not included because of possible additional en-docrinological and/or morphological disorders. Linear measurements included length, depth, and diameter. The shape of the sella turcica was analyzed in the cleft and noncleft groups. An independent f test was conducted to evaluate differences between genders and groups. One-way ANOVA was used to compare age groups

Results: The length [p < 0.001] of the sella turcica was smaller in noncleft subjects than in cleft subjects. Diameter [p = 0.014] and depth [p = 0.005] showed as constantly increasing from an age <15 to >25 years in the overall assessment. The distribution of the shape of the sella turcica differed significantly between groups [p < 0.001]

Conclusions: In this study, CBCT was used to assess the morphology of the sella turcica. A majority of the subjects with cleft had a flattened sella turcica compared to that of the control group. A shorter length of the sella turcica was more evident in the cleft subjects than in the control group

Prevalence of fusion and gemination in permanent teeth in Coppadocia region in Turkey

The objective of the present study was to determine the prevalence of dental fusion and gemination in permanent teeth in Coppadocia region in Turkey. The distributions of these conditions among different types were also studied. The present study was based on the clinical assessment and panoramic radiographs of 8,229 patients. All of these patients were examined clinically and had radiographs and photographs taken at the time of examination. All data [age, sex and systemic disease or syndrome] were obtained from the patient files and analyzed for double teeth [fusion and geminaiton]. The distribution of double teeth was investigated according to types and clinical positions. In this study the prevalence of double teeth [Fusion and gemination] in the permanent dentition in patients between 12 to 60 years was 0.29%. 14 [0.17%] were Fused and 12 [0.14%] were geminated teeth. The maxillary incisors were the most commonly affected, followed by the mandibularpremolars. Fusion andgemanation are uncommon conditions in Turkish population, but they are important dental anomalies that can affect any tooth in the mouth. Recognizing the condition will facilitate the endodontist, prosthodontist, periodontist, orthodontist, and for surgical management of such teeth
