Abstract

Sella turcica is an anatomic point in the cephalometric tracing of orthodontic treatment. The formula for body mass index (BMI) is calculated by using the height and weight of an individual. Objective: To evaluate the size and morphology of the sella turcica in healthy, overweight, and obese patients. Methods: The 66 individuals (24 males and 42 females; mean age, 15.05 ± 1.61 years) selected for the study were divided into three groups: obese; overweight; and healthy, according to the BMI percentile classification. The length, diameter and depth measurements of the sella turcica were measured on a lateral cephalometric radiograph. Results: No statistically significant differences were found among the groups, although the length, diameter, and depth of the sella turcica were higher in healthy individuals (P > 0.05). Moreover, the normal sella turcica, compared with other sella turcica variations, was more common in 64.7% of the healthy patients, 61.1% of the overweight patients, and 64.3% of the obese patients. Conclusions: Normal sella turcica is more common than other types of sella turcica. In addition, no significant difference was found among the groups in terms of length, diameter, and depth of the sella turcica.

Abstract

Objectives: This study aims to evaluate the relationship between the morphological variations of Sella Turcica (ST) and dental anomalies. Methods: This study included 765 individuals between the ages of 13 and 35. ST morphology was examined in 3 groups as no calcification, partially calcified and completely calcified according to the interclinoid ligament (ICL) on lateral cephalometric films, and it was examined and evaluated in terms of its relationship to impacted canines (unilateral and bilateral), impacted teeth (except 3rd molars), root dilaceration, tooth deficiency (upper incisor lateral - lower and upper second premolar), supernumerary tooth and taurodontism. Results: The rates of supernumerary teeth, lateral and premolar tooth deficiency and root dilaceration in total calcification of ICL were significantly higher than those in ICL with no calcification. The rates of taurodontism, unilateral and bilateral impacted canine teeth and impacted teeth in ICL with no calcification were found to be significantly lower than those in the partial and total calcification of ICL. Conclusion: In this study, a statistically significant relationship was found between ST morphology and dental anomalies. Examination of sella turcica bridging (STB) variations in a large population will be guiding for the early detection of dental anomalies.

Abstract

Objective: To compare of pharyngeal airway dimensions and dentoskeletal changes after treatment with twin block (TWB) and monoblock (MB) appliance in growing patients. Methods: The sample was comprised of a total of 72 patients at the ages of 10 to 13. The TWB group consisted of 36 patients (22 females, 14 males, mean age: 11.9±1.5) and MB group consisted of 36 patients (18 females, 18 males, mean age: 11.8±1.2). The linear and angular measurements were evaluated on lateral cephalometric radiographs at beginning (T0) and end of treatment (T1). Results: The amounts of increase in the inferior airway space, L1xNB, IMPA and FMA measurements from T0 to T1 in the TWB group were significantly higher (p < 0.05).In the TWB group, the amounts of the increase in the soft palate thickness, distance between hyoid and C3, Co-A and Co-Gn measurements from T0 to T1 in the female patients were significantly higher (p < 0.05).In the MB group, the amounts of increase in the Upper adenoid thickness and Vertical airway length measurements from T0 to T1 in the female patients were significantly higher (p < 0.05). Conclusion: Both the MB and TWB appliances increase the pharyngeal airway dimensions, and the lower airway is most affected by the appliance type.

Abstract

Objective: This study aimed to compare pharyngeal airway and dentoskeletal effects of 2 and 4 premolar extraction treatments in adult patients separately for each gender. Methods: The study was conducted with 60 adults (26 males; 34 females) aged 18-35 years. Individuals were divided into 3 groups as non-extraction, 2-premolar extraction, and 4-premolar extraction. Pre-treatment (T0) and post-treatment (T1) dentoskeletal and pharyngeal airway measurements were performed on cephalometric radiographs. Results: A significant increase in nasopharyngeal airway (PNS-ad2) and anterior hyoid bone movement (CV3ai-H) was observed in the 4-extraction group; whereas in the 2-extraction group, inferior oropharyngeal airway (IAS) narrowing and hyoid bone movement in posterosuperior direction were observed. In the non-extraction group, inferior oropharyngeal airway narrowing and hyoid bone movement in the anteroinferior direction were observed. A significant increase in nasopharyngeal airway, narrowing of oropharyngeal airway, and superior hyoid bone movement were observed in the 2-extraction group in males. In the non-extraction and 4-extraction groups, the hyoid bone moved in inferior and anterior directions, respectively. While the hyoid bone moved posteriorly in the 2-extraction group in females, there was an increase in nasopharyngeal airway and narrowing of the middle oropharyngeal airway (MAS) in the 4-extraction group. Conclusion: While the nasopharyngeal airway was widened in individuals with 4-extractions, the inferior oropharyngeal airway was narrowed in both the 2-extraction and non-extraction groups. Hyoid bone movement was observed in anterior, posterosuperior, and anteroinferior directions in 4-extraction, 2-extraction, and non-extraction patients, respectively, and these changes vary according to gender.
