A bstract Aim and objective The aim and objective of this study was to do a comparative evaluation of microhardness and enamel solubility (ES) of the treated surface enamel with resin infiltrant, fluoride varnish, and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP). Materials and methods An in vitro study was conducted on freshly extracted 85 sound permanent teeth of which 5 teeth were subjected to check for microhardness by the Vickers microhardness tester and the remaining teeth were exposed to demineralizing solution to create initial enamel lesions. These 80 teeth were assigned to four groups: group I—negative control ( n = 20), group II—resin infiltrant ( n = 20), group III—fluoride varnish ( n = 20), and group IV—CPP-ACP ( n = 20), and microhardness was checked after application. These teeth were exposed to caries attack three times a day for three consecutive days. The ES of these four groups was checked by calcium ion loss in the artificial cariogenic solution and whole saliva by an atomic absorption spectrophotometer. Results It was found that none of the experimental groups reached the microhardness values of sound intact teeth. At 3rd day, the values of microhardness were: group II = group III > group IV > group I. Maximum ES was found for group I (control) followed with group IV. Conclusion All agents used in study remineralized initial carious lesion. Fluoride varnish has the highest microhardness and showed least ES compared to other remineralizing agents. Clinical significance Fluoride varnish can be regarded as the choice of material to be used for the treatment of incipient carious lesions because of the low application frequency (once every 3–6 months), requires minimal patient compliance as it is a noninvasive procedure and less time consuming.

Background: Dental plaque, a microbial biofilm, is the primary etiological factor leading to the initiation of gingivitis and dental caries. It is therefore important to prevent it by taking effective plaque control measures. This research aimed at comparing the anti-plaque and anti-gingivitis effects of green tea (GT), GT plus ginger (GT + G), and chlorhexidine mouthwash (CHX) in children. Materials and Methods: This was a randomized clinical trial, with a sample size of 60 children between the age group of 10–14 years with plaque and gingivitis. They were randomly allocated in three different groups, depending upon the mouthwash used: Group A (GT mouthwash), Group B (GT plus ginger mouthwash), and Group C (CHX mouthwash). Plaque index and gingival index were recorded at baseline, then at interval of 15 days and 30 days after using mouthwash. Results: The mean gingival score and plaque showed a significant reduction from the baseline among all the three groups when compared with subsequent recall visits (15 days after using mouth-rinse and 30 days after using mouthwash) with P < 0.05. Conclusion: It can be concluded that the results of all three groups are comparable and hence herbal mouthwash can be used effectively as an alternative to CHX and as an adjunct to mechanical plaque control.

Introduction: In forensic odontology, Dental Age (DA) assessment has gained popularity, since it is less variable than other indices and is less impacted by environmental variables. One of the methods used in estimating dental development is radiological method which is most practical and reliable. Aim: To compare accuracy of Demirjian’s, Willems, Nolla’s and modified Cameriere’s DA estimation methods in young western Indian children. Materials and Methods: This cross-sectional observational study was conducted in the Department of Paediatric and Preventive Dentistry, KM Shah Dental College and Hospital, Sumandeep University, Vadodara, Gujarat, India, from May 2014 to May 2017. A total of 224 orthopantograms (OPGs) of children aged between 3-11 years having the anthropological roots in the western part of India, were analysed for the accuracy of the following age estimation methods: 1) Demirjian’s; 2) Willems; 3) Nolla’s; and 4) Modified Cameriere’s method in various age group ranges and in both the genders of the study population. To avoid observer bias, each digital OPG of an individual was coded with a numerical identity number. Results were analysed using unpaired t-test and Spearman's correlation test (p-value <0.05). Results: An over estimation was observed in the Demirjian’s and Willems DA estimation methods in all the age groups and both the genders, while modified Cameriere’s method gave over estimation in the older age groups and approximation to the Chronological Age (CA) in younger age groups. Nolla’s method proved to be the best method in study population. Conclusion: Nolla’s method of age estimation was more accurate than other methods for determining the age in 3-11 years old western Indian children.
