Normal 0 false false false EN-US X-NONE AR-SA This article is aimed to evaluate blood pressure changes in 100 patients (Normotensive and hypertensive) of dental clinics.  Blood pressure changes were recorded in particular stages: before surgery, 2 minutes after receiving local anesthesia, during surgery and 15 minutes post surgery. Results were analyzed via student paired T test to identify if there were any significant difference between two groups of normotensive and hypertensive and this was dangerous or significant enough to prohibit patients from receiving dental treatments.

Statement of Problem: Hemodialytic patients may be exposed to periodontal diseases during treatment. No information of any kind is available regarding the periodontal treatment needs of such patients.

Purpose: The aim of the present study was to determine the periodontal treatment needs of hemodialytic patients, living in Tehran, to be presented to the public health system.

Materials and Methods: In this descriptive study using CPITN index 75 patients according to multi-stage sampling method and in proportion to the number of patients in Tehran were selected. Following necessary training, qualified subjects were chosen and a special questionnaire was completed for each using personal protection, CPITN index, by WHO prob, was examined and numbered according to (0-4) codes. Results: The findings showed that 10.6% of the patients had normal periodontal status (Code-0), 12% of the patients had bleeding upon probing (code-1), 21.4% had calculus (Code-2), 21% of the patients had shallow pockets (Code-3) and 24% had deep pockets. It was also shown that 89.4% of the patients needed oral hygiene instruction, 77.4% needed scaling and 24% required advanced periodontal treatments whereas only 10.6% did not need any treatment.

Conclusion: No statistically significant relationship was found between periodontal status and factors such as age, sex, the history of hemodialysis treatment and level of patients’ education.

Background and Aim: In recent years, CT scan has become available as an alternative to conventional radiography. To date, the utility of Waters view in detecting midface fractures has been rarely evaluated. The aim of this study was to compare the diagnostic accuracy and reliability of Waters radiography with CT scan in detecting midface fractures.

Materials and Methods: In this tests evaluation study, waters view and CT scan were performed for 42 patients with midface fracture admitted to maxillofacial surgery department of Shariati hospital. All images were observed and interpreted by an oral and maxillofacial radiologist and an oral and maxillofacial surgeon. Sensitivity, specificity and reliability for Waters view in detecting midface fractures were assessed by Cohen’s kappa test.

Results: Sensitivity and specificity for Waters view in detection of midface fratures by the radiologist were 31.79% and 95.35% and by the surgeon were 29.59% and 93.75% respectively. The highest reliability in CT scan and Waters view (in nasal fractures) by the radiologist was 66.67% and was 58.33% by the surgeon in buttress of zygoma. The highest agreement rate between the radiologist and the surgeon for CT scan was in zygomatic arch (78.95%) and for Waters view was in nasal fracture (62.5%).

Conclusion: Based on the results of this study, the specificity of Waters view is sufficient to diagnose fractures of lateral orbital wall, infraorbital rim, orbital floor, zygomatic arch, frontozygomatic suture, lateral wall of maxillary sinus and Lefort II fracture. The specificity is not sufficient to diagnose fractures of medial orbital wall and anterior, posterior and medial wall of maxillary sinus. Detection of these midface fractures needs other conventional radiographies or CT scan.
