  Background and Aims: The routine mechanical plaque control is done by toothbrush. With regard to different designs of tooth head brushes in order to better plaque removal, the aim of this study was to evaluate the effect of between teeth and cross-action tooth brush on the plaque and gingival status among dental students of dental branch-Islamic Azad University during 2012-13 academic years.

  Materials and Methods: This single-blind, cross over, clinical trial was conducted on 30 subjects with mean age (23±0.9) in two groups of 15 persons . They had at least 20 teeth and had gingivitis with no history of antibiotic use in the last 3 months. Those who were undergoing orthodontic treatment, using drugs affecting the gums and having crown and bridge were excluded from the study. The first group used the cross action toothbrush and the second group used between teeth toothbrush and the subjects were asked to brush their teeth for two minutes twice a day in modified bass method and not to floss during the execution of this study. After 14 days plaque index (Turesky, Approximal plaque index) and gingival bleeding index were recorded on all teeth except third molars. After a week wash out period, second stage of the study was conducted the same as the first stage with the other kind of brush for each group. Data were analyzed using Generalized Linear Model (GLM) test.

  Results: There was no statistical significant difference between two toothbrushes based on plaque index, gingival bleeding index and approximal plaque index, respectively (P = 0.29, P = 0.47, P = 0.33). In all measured indices, the treatment sequence showed no significant difference (P = 0.23).

  Conclusion: There was no statistical difference between cross-action and between teeth toothbrush in reducing plaque and gingival bleeding.

Background and Aims: Type 1 diabetes mellitus, is the most common metabolic disorders in children and adolescents. The aim of this study was to assess the state of oral health in children with type 1 diabetes compared with healthy children in 2013-2014 in Hamadan province, Iran.

Materials and Methods: The specimens were selected through convenience sampling in two groups. Group one consisted of 80 individuals (5-18 years old; case group), suffering from type 1 diabetes mellitus referred to the Pediatric endocrine clinic. Control group consisted of 80 non-diabetic healthy children who were out- patients of pediatric and orthodontic department of Hamadan dental school. Two groups were similar in age and sex. The data were collected through a questionnaire, medical records and clinical examination. DMFT, dmft, GI and PI indices were assessed in each patient. Data were analyzed using ANOVA and T-test.

Results: In spite of similarity in oral hygiene habits in both group, there was no significant difference in mean DMFT and permanent decayed teeth in both groups (P>0.05), but the mean dmft (P<0.008) and primary decayed teeth (P<0.011) in the control group was significantly higher than that of the case group. Also, diabetic patients had significantly more gingival inflammation (P<0.05). The mean PI in the two groups did not differ significantly. Oral hygiene habits were similar in both groups but diabetic patients were significantly referred to dentists with lower frequency then that of control group (P=0.00).

Conclusion: The devastating effects of diabetes on the oral health, along with other side effects can be effective in promoting tooth decay and gingivitis in diabetic patients. Unfortunately, oral health care and programmed dental visit were not the priority for the diabetic patient (and parents) involved in our study. Therefore, programs to increase awareness and encourage patients for a better control of their oral health in order to diminish diabetes' devastating effects is recommended.
