The 1% tannin green tea mouthwash could be a safe and feasible adjunct to mechanical plaque control. The tested green tea mouthwash could be considered a good alternative for chlorhexidine in contraindicating situations.

Deciding whether to replace or preserve a compromised tooth, even with emerging trends in implant dentistry, is still a common dilemma for practitioners. This study sought to determine the 3- to more than 10-year survival rate of teeth that had undergone endodontic, periodontal and prosthodontic treatments. A total of 245 teeth in 87 patients were clinically and radiographically evaluated. All the teeth had received crown lengthening surgery by a single periodontist. Root canal therapy and prosthodontic procedures were rendered either by specialists or by experienced general dentists. Numbers of lost teeth were recorded and the criteria for hopeless teeth were defined. Survival rate was determined using the Kaplan-Meier estimator. Clinical indices including pocket depth (PD), bleeding index (BI), C/R ratio, position of the restoration margin relative to the gingival margin (RM-GM) and the presence of intra-canal post were compared between different survival groups (<3, 3-5, 5-10 and >10 years) using one-way analysis of variance (anova). Potential predictors of failure were determined using the Cox regression model. The mean ± s.d. of 3-, 5-, 10- and 13-year survival rates was 98 ± 1%, 96 ± 1·6%, 83·1 ± 4·5% and 51·9 ± 14·5%, respectively. The mean PD (P < 0·013), as well as C/R ratio in the mesial (P = 0·003) and distal (P = 0·007) surfaces, was significantly higher in the >10-year-survived teeth. Bleeding index and RM-GM showed no significant differences between the groups. C/R ratio and RM-GM position appeared to be the major determinants of tooth loss. The long-term survival rate of multidisciplinary-treated teeth was 83-98% in this specific sample.

The World Health Organization recognizes oral health as an integral part of public health and believes that untreated oral diseases may greatly affect the quality of life, especially in pregnant mothers who should maintain their health and their babies' health. Objective: This study aimed to determine the effect of educational intervention based on a health belief model on oral and dental health behavior in pregnant women. Materials and Methods: In this randomized clinical trial, 110 pregnant mothers attending 15 health centers in Rasht City, Iran (a total of 33 centers) were randomly allocated to case and control groups. After the analysis of pretest data (collected using a psychometric questionnaire), an intervention was designed and executed based on the Health Belief Model (HBM). Post-test was administered three months after the intervention and the obtained data were analyzed by using the Chi-square and independent and linear regression test. Results: The majority of the mothers in the case (83.6%) and control (89.1%) groups were 18-30 years old and most mothers in the case (45.5%) and control (58.2%) groups had high school education. The Mean±SD score of awareness, different constructs of HBM, and performance increased significantly in the case group after the intervention (P<0.05). The Mean±SD score of performance was 35.45±12.52 in the case group before the intervention and it increased to 77.26±9.33 three months after the intervention (P<0.05). Conclusion: The results showed that intervention based on this model enhanced oral and dental health behaviors. The results also suggested that the mothers lacked adequate awareness and had a poor performance in adopting oral and dental health behaviors. This model can be used as a framework for designing and implementing educational interventions to decrease dental caries.

Introduction:Oral and dental health is viewed as one of the most important domains of public health, which is of over riding importance among mothers who, with regard to their role in maintaining their health and their children's health, are considered one of the vulnerable groups. Materials and Methods:This is a cross-sectional study in which 110 pregnant mothers referring to 15 Health Treatment Centers of Rasht (totally 33 centers) were randomly selected. The data were collected by distributing a questionnaire with items on awareness, different dimensions of the Health Belief Model (HBM), and practices in relation to oral and dental health care. The data were then analyzed. Results:Findings showed that the mean practice score of mothers on "the practice of oral and dental health care by pregnant women" was 37.5±15.9 in relation to oral and dental health care for pregnant women. Awareness (ß = 0.382) and among the structures of the Health Belief Model, perceived sensitivity (ß = −0.263) and perceived obstacles (ß = −0.367) were the most significant predicting factors of behavior of oral and dental health in pregnant women. These variables indicated 20% variance for oral and dental health care behavior. Conclusion:This study indicated the efficiency of the health belief model (HBM) in predicting behavior promoting oral and dental health among pregnant mothers.
