This study represents the morphology and measures the size and shape of the sella turcica in Bangladeshi populace and contrast with accessible global information. A sum of 166 (108men and 58 ladies) Bangladeshi subjects who went through Computed tomography (CT) scan at the Radiology Department were taken. A 3D imaging software (Mimics 11.02 Materialise) was utilized to process the CT images. Morphometric strategies were utilized to evaluate size and shape. The parameters for conventional measurements were three dissimilar sella height (anterior, posterior and median), sella length, diameter and width, where all of them deliberated in relation with Frankfort reference line (FH). Total area of sella turcica also considered. No important contrasts in size of the sella were found between sexes. The study found that sella turcica gave three unique shapes which were considered flat (28.3%), ovoid (48.1%) and circle (23.4%). In another morphological classification sella turcica represent 6 different variations. Those were normal sella (69.2%), oblique anterior wall (4.8%), double contour of sella floor (6.6%), sella turcica bridge (0 %), irregularity (notching) in the posterior part of the dorsum sella (16.2%) and pyramidal shape of dorsum sella (3.0%). Sella shape and measurements reported in the present study can be useful in giving reference information in the orthodontic determination, appraisal and treatment arrangement and evaluation of sex dimorphism in Bangladeshi subjects.

To determine the prevalence of incidental maxillary sinus fi ndings and assess their relationships with age and gender. CBCT scans of 412 patients, comprising of 824 maxillary sinuses were evaluated. The maxillary sinuses were observed for increased mucosal thickening, polypoidal-mucosal thickening, opacifi cation and other pathological changes. Correlations of these pathologic fi ndings with age and gender were analyzed. The incidence of the pathological fi ndings in maxillary sinuses observed was 30.1%. The most common abnormality observed as mucosal thickening followed by opacifi cation. No signifi cant correlation was observed between genders and diff erent age groups. Based on the observations of the present study, it can be concluded that the prevalence of incidental maxillary sinus abnormalities in Saudi Arabian observed on CBCT is considerably high.

The aim of this study was to determine the maxillary expansion index (MEI) for Pakistani population. Also to determine the sexual disparities in sum of incisors perimeter, arch width and expansion indices of maxillary arch. Hirox digital stereomicroscope was used for the fabrication of the digital models. The estimated sample size was 128 Pakistanis (64 females and 64 males; age range from18 -24 years). The perimeters of the maxillary permanent incisors, as well as intercanine, interpremolar, and intermolar arch widths, were measured on digital dental models. Significant sexual disparities were observed (***p < 0.001). There was significant difference observed in arch length and arch perimeter group of maxilla. For the prediction of ideal arch width in intercanine, interpremolar, and intermolar region to be achieved at the finishing stage, orthodontist can forecast the arch width before the initiation of orthodontic treatment. The new formula and the new indexes of arch width can be a helpful adjunct in the orthodontic treatment.

We used a combination of arthrocentesis, mouth opening exercises, and nansteroidal antiinflammatory drugs as a primary treatment for temporomandibular joint (TMJ) osteoarthrosis. This study evaluated the long-term results of this treatment by a mail questionnaire. Fifty patients with moderate and severe TMJ dysfunction who had TMJ unilateral osteoarthrosis were followed up from 1 year 6 months to 3 years 3 months (mean: 2 years 4 months) after the combined treatment. Of the 43 patients who returned the questionnaire, 37 (74% ) had an acceptable outcome. Maximal mouth opening, pain on chewing, and pain on opening the mouth at the time of responding to the questionnaire were significantly better than those at time of finishing primary treatment. These results showed that stable effects were maintained after combined primary treatment.
