Comparative Evaluation of Neem Mouthwash on Plaque and Gingivitis: A Double-blind Crossover Study.

AIM: The present study aimed at evaluating the impact of neem-containing mouthwash on plaque and gingivitis. MATERIALS AND METHODS: This randomized, double-blinded, crossover clinical trial included 40 participants aged 18 to 35 years with washout period of 1 week between the crossover phases. A total of 20 participants, each randomly allocated into groups I and II, wherein in the first phase, group I was provided with 0.2% chlorhexidine gluconate and group II with 2% neem mouthwash. After the scores were recorded, 1-week time period was given to the participants to carry over the effects of the mouthwashes and then the second phase of the test was performed. The participants were instructed to use the other mouthwash through the second test phase. RESULTS: There was a slight reduction of plaque level in the first phase as well as in the second phase. When comparison was made between the groups, no statistically significant difference was seen. Both the groups showed reduction in the gingival index (GI) scores in the first phase, and there was a statistically significant difference in both groups at baseline and after intervention (0.005 and 0.01 respectively). In the second phase, GI scores were reduced in both groups, but there was a statistically significant difference between the groups only at baseline scores (0.01). CONCLUSION: In the present study, it has been concluded that neem mouthwash can be used as an alternative to chlorhexidine mouthwash based on the reduced scores in both the groups. CLINICAL SIGNIFICANCE: Using neem mouthwash in maintaining oral hygiene might have a better impact in prevention as well as pervasiveness of oral diseases as it is cost-effective and easily available.

Knowledge, Attitude, and Practice towards HIV Patients among Dentists.

AIMS AND OBJECTIVES: Discrimination by some health care workers, including dentists, against human immunodeficiency virus (HIV) infected persons has been noted. The main aim of the present study was to assess the knowledge, attitude, and practice towards HIV patients among the dentists of Trichur district, Kerala. MATERIALS AND METHODS: A cross-sectional survey was conducted among 206 dentists practicing in Trichur district of Kerala. Data was collected using a pretested, self-administered 26-item questionnaire and was statistically analyzed using SPSS software version 20. RESULTS: Out of 206 participants, 39.3% were unwilling to treat HIV patients. A statistical significance was found between willingness to treat HIV infected patients and age groups (P = 0.0001) as well as between the willingness to treat HIV infected patients and ethical responsibility (P = 0.0001). CONCLUSION: Staff fears and increased personal risk are found to be the most frequently reported concerns in treating HIV patients among dentists of Trichur district, Kerala. Senior dentists showed more reluctance to treat HIV positive individuals.

Effect of fluoridated water on intelligence in 10-12-year-old school children.

AIM: The aim of the present study was to evaluate the relationship of drinking water fluoride levels with children's intelligence quotient (IQ). MATERIALS AND METHODS: Water was collected from initially identified endemic fluoride regions according to the geological research of Government of India. Fluoride concentration of the water was assessed by utilizing fluoride ion selective electrode, Orion 9609BN, and categorized on the basis of fluoride concentration into low, medium, and high-fluoride regions, i.e., Virajpet (low fluoride level < 1.2 ppm), Banavara (Medium fluoride level 1.2-2 ppm), and Mastihalli (High fluoride levels > 3 ppm). Government school from all three villages were selected randomly and IQ levels were assessed by using Raven's Standard Progressive Matrices. This test was conducted on each child in the study sample. RESULTS: A significant inverse relationship was found between the fluoride concentration in drinking water and IQ (r value = -0.204; P < 0.000). It was observed that IQ level was negatively correlated with fluoride concentration in drinking water. CONCLUSION: It is concluded that IQ level was negatively correlated with fluoride level in drinking water. Factors that might affect children's IQ need to be considered, and it is necessary to devise solutions for preventing the harmful effects of excessive intake of fluoride ion to the body.
