Introduction: This study aims at examining the difference of pharyngeal airways in patients with different occlusion postures, hoping to improve diagnostic methods and provide a stable treatment plan for orthodontic patients.
Materials and Methods: The data were ga-thered through CBCT radiographies of patients from a specialized center for radiology. In each occlusion group according to the performed pilot study, 30 people (90 people in 3 groups of class I, II and III, male and female each) were chosen as the sample. The two-dimentional cephalometric radiographs were obtained from 3D-radio-graphs, and the patients’ malocclusion postures were determined according overjet and ANB angle, and finally grouped. Next, airway volume and dimensions were measured in cross sectional.
Results: Statistical studies showed there is a significant relationship between anteroposte-rior positions of mandible and the volume of pharyngeal airway. Also, the volume of pharyn-geal airway in class III patients is more than those of patients in class I. The volume of pha-ryngeal airway in class II patients is also less than those of class1 patients.
Conclusion: Pharyngeal airway in class III is larger and in class II smaller. Therefore, consi-dering this subject can lead to improving diag-nostic ways, especially orthognatic surgery treatments, and providing a stable treatment plan for patients who need orthodentic treat-ment

Introduction: Peripheral odontogenic tumors are rare and there is no valid information of the frequency of them in the literature. This study aims to obtain the frequency of these tumors.
Materials and Methods: The files of oral and maxillofacial pathology (microscopic reports and slides), faculty of dentistry, Shahid Beheshti University of medical sciences served as the source of the material during a 20-year-period for this retrospective,descriptive cross-sectional study. Clinical information including, patient’s age, gender and location was record-ed.
Results: Three hundred seventy nine cases of odontogenic tumors were assessed in which 16 cases (4.22%) were peripheral and 363 cases (95.77%) central. Peripheral odontogenic fibroma was the most common case of the 16 peripherals accounting for 10 cases (62.5%) followed by peripheral ameloblastoma(25%) and peripheral dentinogenic ghost cell tumor (12.5%). The peripheral type of odontogenic fibroma was more common than central counterpart (3.3:1).
Conclusion: In our study, similar to the previous ones, the relative frequency of the peripheral odontogenic tumors was low and peripheral odontogenic fibroma was the most common tumor among other peripheral subtypes. Unlike other types, the incidence of peripheral odontogenic fibroma was higher than the central odontogenic fibroma.

Introduction: Regarding the cross contamina-tion, prevention from infection is of high priority. The aim of this research was assessment of knowledge and attitude of dental students toward infection control in endodontics department of faculty of dentistry, Babol University of medical sciences.
Materials and Methods: The study was accomplished among 8th, 10th and 12th grade dental students in endodontics department during October-January, 2011. The student's knowledge and attitude towards infection control were investigated. The range of knowledge score was 8 to 19. The scores below 14 were considered low and between14 to 17 moderate and higher than 17 good. The attitude questions also included 3 answers (agree, disagree and have no idea). Their scores were -1, 0 and 1. The range of attitude score was -6 to 8. The scores below -2 were considered low and between -2 to 2 moderate and higher than 2 good. Data were collected via questionnaire and analyzed statistically using One-Way ANOVA, and HSD Tukey.
Results: There was no significant difference between men (15.45±2.85) and women knowledge (15.2±2.7) (P=0.65) and attitude (0.2±2.5 vs. 0.35±2.49) (P=0.5). The difference between 8th and 12th semester was statistically significant (p=0.026). There was no significant difference between different semesters in attitude (p=0.94).
Conclusion: This study revealed that knowledge and attitude of Babol Dental School toward infection control is not adequate and more training in both educational and practical fields is required.

Introduction: Periodontal disease, an inflamma- tory and infectious disease in adults and anemia associated with chronic infection, is one of the most common types of anemia. Considering the similarity of pathogens causing periodontal disease and anemia, this study aims to investigate the correlation between hematologic parameters associated with anemia and moderate chronic periodontitis.
Materials and Methods: This case-control study was systematically performed on blood samples of 60 healthy men. The control group consisted of 30 men who had healthy periodontium and the case group included 30 men with moderate chronic periodontitis. Clinical examination of patients was done using Williams periodontal probe and assessment of CAL, PPD, BOP and GI. Blood samples were collected at the Depart- ment of Periodontology, Babol school of Dentistry and evaluation of red Erythrocyte indices, Hemoglobin, Hematocrit, SI and TIBC was done. Data collected from clinical examinations and laboratory tests were analyzed by T-test, Pearson correlation coefficient and Spearman tests.
Results: Reduction of MCV, MCH, Hb, HCT, SI and TIBC factors were observed with increasing GI and CAL and BOP. There is no significant correlation between GI and CAL and BOP and MCHC factor. No Significant correlation exists between PPD changes and hematological factors associated with anemia.
Conclusion: A correlation was observed between some hematological parameters associated with anemia and moderate chronic periodontitis.

Introduction: Dentin dysplasia is a rare autosomal dominant inheriting disturbance of
dentin formation characterized by normal
enamel formation, but atypical dentin with
abnormal pulpal morphology. There are two major patterns: type I and type II. Amelogenesis imperfecta is an autosomal dominant. X-link inherent disease that is classified by clinical manifestation into hypoplastic, hypomature, hypocalcified.
The simultaneous occurrence of dentin
dysplasia and amelogenesis imperfecta is quite rare. The purpose of this case report is to pre-sent a case of dentin dysplasia type I which is also associated with hypoplastic amelogenesis
imperfecta in an 18 year old girl, without any syndromic signs.
