Abstract
The purpose of this article is to study distribution of DMF(T) and its D,M and F protions exactllly. 1500 subjects were examined clinicaly. They were 5 to 70 years old, with average 24 years. Only cavitated and coronal dental caries included in this research.
The results of this study are:
1. The caries lesions of upper and lower second permolars are equal.
2. Anterior to second premolars, the DMF(T) of upper jaw teeth is higher than lower jaw's one. Conversely posterior to second premolars, lower jaw teeth has higher DMF(T).
3. Deciduous teeth of females have lower DMF(T).
4. Permanent teeth of females have higher DMF(T).
5. The upper Canines of females are exceptions. Upper canines of females have lower DMF(T) than males' ones.
6. It seems that sex hormones influence DMF(T) through Saliva and eruption time of teeth.
7. Susceptibility to Caries relates to microbial plaque formation and salivary protection.
8. The females have more filled teeth than males.

Abstract
Epidemiologic studies have shown that caris or "infective damage of hard tissues in teeth" are the most common type of infection in human. In Iran, a few studies have investigated this hygienic problem, but no practical results have been defined yet. In this research, the conditions of the first upper and lower permanent molars (it contains four minor variables), have investigated. For this reason, in a descriptive analytic study, which was of retrospective and cross- sectional type, one thousand files were chosen systematically. The data were analysed by SPSS packages. The mean values of DMFT for permanent first molars were 3.47±0.50 (MT-1.23, FT=0.86, DT-1.38). The number of extracted teeth in mandible was moer than maxilla and the number of untreated caries teeth in maxilla was more than mandible (PO.001). DMFT ratio of the first molars to total DMFT, was approximately 29%, which indicates that caries and that complications on the first molars, make the main part of the overall DMFT. Therefore, hygiene training, preventive methods and the improvement of ecomonical status seem necessary in dental services.

Abstract
Background and Aim: Aggressive periodontitis is one of the periodontal diseases, which affects systemically healthy individuals usually under the age of 30 years old. The disease is characterized by rapid bone destruction which is not in accordance with the quantity of bacterial plaque. The purpose of the present study was to determine the prevalence of aggressive periodontitis among 15-18 years old female students in Tehran high schools.
Materials and Methods: In this cross sectional study, , 2870 students were selected from all educational areas of Tehran during 1382-83 based on systematic clustered random sampling .Probing pocket depth on 6 areas of incisors and first molars were examined in each subject. Students with pocket depth equal to or more than 4 mm on more than one tooth were referred to Shahed Dental School for radiographic examination. For cases in which the distance between the crest of interdental septa and CEJs were equal to or more than 2 mm, full clinical and radiographic examination was performed.
Results: Among the subjects of study, only 4 fulfilled the diagnostic criteria of localized aggressive periodontitis. Nobody was diagnosed with generalized aggressive periodontitis. The prevalence of aggressive periodontitis among 15-18 years old schoolgirls was 0.14%.
Conclusion: The results of the present study were similar to previous studies with the same age groups and diagnostic criteria in other countries. For determination of total prevalence in Tehran, similar studies in schoolboys are recommended.

Abstract
Background and Aims: Association between patient satisfaction and success of the treatment determines the quality of health care. Measuring the level of satisfaction is an important factor for improving the quality of services provided by a system, so it is necessary to determine the expectations of patients. The aim of this study was to evaluate the patient satisfaction from services provided by the dental faculty of Tehran University of Medical Sciences.
Materials and Methods: In this descriptive and cross-sectional study, 385 patients were randomly selected from different departments of dental faculty including prosthodontics, endodontics, periodontics, operative dentistry, radiology and oral medicine. A two-part questionnaire including demographic characteristics of patients and satisfaction from reception process, infection control, student and personnel behavior, and the outcome of treatment was filled out by patients. Data were analyzed using SPSS software.
Results: The most dissatisfying factor was the time wasted in paying the cost and the most satisfying factor was student behavior. General satisfaction form the process was evaluated (complete satisfaction 51.9%, partial satisfaction 38.4% and dissatisfaction 9.6%), and 62.9% of patients were completely agree with introducing dental faculty to others.
Conclusion: The most satisfying item was student behavior which indicates that this factor is of great importance in increasing the quality of treatment. The deficiencies determined by patient can provide reliable data for determination and regulation of health care policies.

Abstract
Background and Aims: Nowadays, removable partial dentures are applied to patients who are not able to use dental implants or fixed prosthesis. Although based on the studies the users of removable partial dentures are in the risk of plaque accumulation and unacceptable changes such as gingivitis, periodontitis and mobility in abutment tooth. It is not clear whether the negative effects of removable partial dentures are more on the isolated teeth which are a kind of abutment adjacent to endentulous area in both sides. The purpose of this study was to investigate the clinical condition of isolated abutment teeth without splinting in comparison to control abutment from the aspects of B.O.P (bleeding on probing), mobility, pocket depth and gingivitis.
Materials and Methods: In this cross-sectional study, the prepared questionnaires were filled out by 50 patients who received removable partial dentures in department of removable prosthodontics of dental school of Tehran University of Medical Sciences. The patients had isolated abutment tooth and did not have any systemic disease. The obtained data were analyzed. Using Wilcoxon, exact Fisher and Kruskal-Wallis test.
Results: B.O.P (P=0.004), pocket depth (P=0.035), and mobility (P<0.001) in isolated abutments were more than those in control abutments, but there were not significant differences in the degree of caries (P=0.083) and gingivitis (P=0.07).
Conclusion: This study showed that clinical condition of isolated abutments is worse than that of control abutments. More attention should be paid to healthiness of isolated teeth without splinting and periodic follow ups should be done in these cases.

Abstract
Background and Aims: The emergence of social web and impact on the communication of the individuals and the scientific activities of various communities has created serious research links among researchers. This issue that how Iranian researchers keep up to date themselves with new technologies and use them to engage in scientific issues has been a challenge that is constantly being addressed in the digital world. Therefore, the purpose of this study was to evaluate the scientific production of dentistry in Tehran University of Medical Sciences in the networks of ResearchGate and Mendeley using the Scopus citation database between 2015 and 2016.
Materials and Methods: The study population included all scientific articles in the field of dentistry of Tehran University of Medical Sciences which were indexed in Scopus database between 2013-2016. The results were presented using descriptive statistics in the form of charts and tables.
Results: In this study, it was determined that the scientific outputs of the researchers from Tehran University of Medical Sciences increased in 2015 and 2016. It was also found that the coverage of articles in the field of dentistry published by researchers at Tehran Medical Sciences Universities in the Scopus citation database in the mentioned years, were in a good position in both the Mendeley and ResearchGate networks. In addition, the number of references to the articles by researchers at Tehran University of Medical Sciences on the ResearchGate network in the field of dentistry was more than the Mendeley network.
Conclusion: Based on the results of this study, it can be concluded that the performance of the researchers of the Tehran University of Medical Sciences in the field of oral and dental care and the extent of their coverage in the social networks of ResearchGate and Mendeley was high and desirable.
