Thalassemia major is one of the most prevalence congenital diseases in the world. This disease is wide spread in Iran and created some problems for health-care system. The aim of this study was to determine of situation oral health among thalassemic patients of Qazvin city in 2013.
In this descriptive - analytic study, thalassemic patients were selected with census method (n=60). Data were collected with examination, and interview. Questionnaire was include demographic, clinical and paraclinical information. Patients were examined and followed up by a dentist. DMFT index was determined on the basis of the examinations. Validity and reliability of the questionnaire was conducted. Data were analyzed by descriptive and analytic statistic tests with SPSS, version 16.
The majority of patients were female (%61.2) and had a history of blood transfusion (%67.3). The most of patients (%83.7) had no history of dental visit and most of them (%77.6) had no tooth brushing. The majority of patients had varying degrees of tooth decay. DMFT index was %57. The frequency of brushing and age had significantly effects on tooth decay (P Thalassemic patients have more problems in comparison other people. Diagnostic and therapeutic procedures have increased their survival. . Thus health indicators include oral and dental hygiene should improve in these patients specially.

The effects of aggressive periodontal disease in several clinical studies are shown. Knowledge, attitude and practice of dentists in this regard can lead to better diagnosis and timely treatment of patients.

The aim of the present study was to evaluate the knowledge, attitude and practice of dentists on aggressive periodontal disease in Qazvin.

This was a cross-sectional study carried out on 140 general dental practitioners in the province of Qazvin (Iran) in 2010. A questionnaire was the data gathering tool of the study and prepared according to the reliable sources. After completing the questionnaire, the data was analyzed by SPSS software using the Pearson correlation test, t-test, and ANOVA.

The average knowledge score (p=0.004; F=5.89), attitude (p=0.018; F=4.18), and practice (p=0.468; F=0.765) of individuals decreased with increased experience. The highest mean attitude score (1.3±5.19) and function (1.16±3.44) were found in dentists under 30 years and the lowest average score (1.03±2.64) in individuals older than 41 years. The average score of knowledge, attitude, and performance was higher in women than men (1.76±5 versus 1.5±3.48; p=0.003; T=-3.04).

Based on results found in the present study, the inclusion of topics regarding the aggressive periodontal disease through retraining courses seems to be necessary in promoting the professional knowledge of dentists.

Aggressive periodontitis is associated with widespread systemic inflammation. C-reactive protein is known as a mediator capable of establishing a connection between periodontal disease and several systemic diseases. Some studies have shown that C-reactive protein is superior to cholesterol in predicting cardiovascular problems and death as a result of cerebrovascular accidents. Previous studies have demonstrated the relationship between periodontitis and high serum levels of C-reactive protein in various societies. The present study compared the effect of periodontal surgeries and conventional non-surgical treatment modalities on C-reactive protein level variations in patients with moderate-to-advanced generalized periodontitis. In this clinical trial, 80 systemically healthy individuals with an age range of 28-37 years, who had moderate-to-advanced generalized periodontitis, were selected and divided into two equal groups of 40. One group was treated by conventional periodontal modality (scaling) and the other was treated by surgery. The subjects’ medical and periodontal parameters, including C- reactive protein serum levels, pocket depth, bone loss and clinical attachment loss, were measured before and six months after treatment. Data was analyzed by SPSS 15 software using independent and paired t-tests (α = 0.05). The results showed that both treatment modalities decreased C-reactive protein serum levels, with the surgical treatment having a greater role in the decrease without any significant differences. Both treatment modalities significantly decreased pocket depths, but there was no significant reduction in the attachment loss and bone loss. It appears surgical periodontal treatment results in a greater decrease in C-reactive protein levels compared to non-surgical techniques but further studies are necessary.
