The results of the present study clearly indicate the superior efficacy of 6% citric acid than the other tested irrigants on removing the smear layer in primary teeth root canals.

Aims and Objectives:The present study was conducted with the aim of evaluating the effectiveness of a Primary Preventive Dental Health Education Programme conducted for 6–12-year-old primary school children in Mysore City.Materials and Methods:A total of 12 schools, one each in the category of Government, Aided, and Unaided, were randomly selected per zone viz., North, South, East, and West. These 12 schools constituted the study group where the Primary Preventive School Dental Health Education Programme (PPSDHEP) was implemented. Two additional schools were selected at random from the four zones to serve as the control. A total of 926 children participated in the study. The PPSDHEP involved the second-level transfer of preventive package wherein the oral health education was imparted to the school children by schoolteachers trained by the investigator. Among the parameters for evaluating the outcome of the programme were the pre and post-programme assessment (at the baseline and at follow-up, i.e., after 6 months) of knowledge, attitude, and practice (KAP), dental caries status, oral hygiene, and gingival health status.Results:The results suggest that the PPSDHEP resulted in bringing about an enhancement in the KAP towards oral health and also an improvement in dental caries, oral hygiene, and gingival health status of the school children in the study group.Conclusion:The present study supports the implementation of similar programmes in schools and the contention that schoolteachers are suitable personnel for imparting dental health education to school children on a regular basis.

The present study proves a strong relation between asthma and dentoalveolar morphology.

As compared with artificial saliva both CPP-ACP and CPP-ACFP produced significant amount of remineralization of the artificial enamel white spot lesion (P < 0.001), however when the remineralizing effect of CPP-ACP was compared with the remineralizing effect of CPP-ACFP there was no significant difference. Significant amount of remineralization was produced by CPP-ACP and CPP-ACFP only after the 7th day. After the 14th day, the remineralization produced by both CPP-ACP and CPP-ACFP as compared to artificial saliva was non-significant.

The fluoride release (ppm) was found to be higher in Giomer when compared with Compomer. The fluoride released from Giomer and Compomer was significantly higher in the acidic demineralising solution than in the neutral remineralising solution. It was found that increasing fluoride exposure significantly increased fluoride release from Giomer and Compomer. It was found that the fluoride release from the subgroups of Giomer and Compomer was in the following order: fluoridated dentifrice twice-daily > fluoridated dentifrice once-daily + fluoridated mouthwash > fluoridated dentifrice once-daily > control group. It was found that Giomer showed a greater fluoride uptake Compomer.

Aims and objective : To evaluate and compare the effect of coffee, chocolate drink and food dye on the color stability of conventional composite resin and nanocomposite resin. Design :The study sample consists of microhybrid composite and other nanocomposite of shade B1. 40 disks of each material with a diameter of 18 mm and thickness of 1 mm were prepared before discoloration procedure specimens were measured for L* a* b* values and then 10 specimens of each subgroup were immersed in each of three staining solution. The 10 remaining specimens of each main group were immersed in control solution.Discoloration values were analyzed at baseline, 1 week and 4 weeks following immersion in staining solution. The color and color difference of each specimen were measured by spectrophotometer. L* a * b* values of each specimens were measured 3 times by placing each specimen on the measuring head. Resistance to staining effect is expressed in ∆E unit and was calculated from the mean ∆L* a* and ∆b* values for each specimens with the following formula.Result : Result of study showed that nanocomposite is more stain resistant and color change ∆E*. Conventional composite demonstrates unacceptable color change ∆E* more especially in specimens immersed in coffee. Conclusion :The result of this study indicated tested conventional composite resin was more susceptible to change in color in various media over an extended period of time as compared to nanocomposite.

The fluoride release (ppm) was found to be more in Giomer when compared to Compomer. The fluoride released from Giomer and Compomer was significantly greater in the acidic demineralizing solution than in the neutral remineralizing solution. It was found that increasing fluoride exposure significantly increased fluoride release from the giomer and compomer. It was found that the fluoride release from the subgroups of giomer and compomer was in the following order: fluoridated dentifrice twice daily > fluoridated dentifrice once daily + fluoridated mouthwash > fluoridated dentifrice once daily > control group. It was found that the giomer showed a greater fluoride uptake than the compomer.

Background:Information on oral health knowledge and practice in orphanage house children is essential for healthcare policy makers to promote oral health resources and address oral health needs of this unprivileged group of society.Objectives:To assess the source of information, level of knowledge, attitude, and practice toward oral hygiene and oral health among socially handicapped children from city of Mysore, Karnataka state, India.Materials and Methods:A cross-sectional survey was conducted among 488 children of 12-14 years of age living in five different orphanage houses of Mysore district. Data regarding knowledge and practice were collected through structured questionnaire and oral health status by type III clinical oral examinations by two trained examiners. Decayed, Missing, Filled, Teeth (DMFT) and OH I-S was then correlated with the above information. Spearman's correlation test was used to measure the correlation.Results:The final data analysis included 488 children, of which 216 (44.26%) were boys and 272 (55.74%) were girls. A total of 88.5% children showed one or more decayed teeth in their oral cavity, with an overall mean DMFT of 3.55. Among DMF, component D showed maximum value with mean 3.42, followed by components F and M. Correlation between source of information, knowledge, and attitude for oral health to oral hygiene index (OHI-S; P < 0.05) and gingival index (P < 0.001) showed highly significant negative values. Correlation between oral hygiene practice to OHI-S, DMFT, and gingival index (P < 0.001) showed highly significant (P < 0.001) negative values.Conclusions:Although children of orphanage have positive attitude toward oral health, knowledge and practice among children are still below the satisfactory level. The children did not receive appropriate information or, if informed, were not re-evaluated or reinforced for its practical application by the concerned authority. The findings of this study suggest that awareness on the importance of oral health needs to be enhanced among the orphanage children of Mysore.
