RESUMO
The requirement for clinically effective treatments to remineralize early enamel caries lesions is dictated by the principles of minimally invasive dentistry. Numerous studies outlined the significance of treating early carious lesions with different remineralizing agents. This study aimed to evaluate and compare the remineralization potential of topical cream containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and CPP-ACP with fluoride in remineralizing artificial carious lesions on enamel. Forty-five freshly extracted human premolar teeth were selected as samples. These samples were divided into three groups: Group I-regular toothpaste without specific remineralizing agent; Group II-topical cream containing CPP-ACP and Group III topical cream containing CPP-ACP with fluoride. All the samples were viewed under scanning electron microscope (SEM) to assess the topographical pictures of the enamel surface and also subjected to energy dispersing X-ray analysis (EDX) for quantitative estimation of minerals, calcium (Ca), and phosphorous (P). In the result of the study, Group I does not show any increase in the Ca and P after applying toothpaste without any remineralizing agent but Group II and Group III showed a net increase in Ca and P- values after applying concerned remineralizing agents. Intergroup comparison showed Group III yielded higher net Ca and P- values than Group II. Two remineralizing agents showed remineralization potential on samples. Descriptive statistics were used to calculate the mean and standard deviation. Mann-Whitney test was used. The level of significance was set at 0.05. CPP-ACP containing fluoride showed better remineralizing potential than CPP-ACP. Hence, CPP-ACP containing fluoride can be considered the material of choice in remineralizing early enamel carious lesions.
RESUMO
BACKGROUND: Dentists are the common preys for the transmission of pandemic disease because of the airborne spread via routine dental checkups. This study which is a cross-sectional one gives the idea about awareness and alertness of dentists about COVID-19 in Kerala, India. MATERIALS AND METHODS: The survey comprised 25 closed-ended questions. The survey was separated into two sections. The initial segment of the poll was identified with the socio-segment qualities that were researched, while the subsequent part was worried about dental practitioners' perspectives toward the management of COVID-19 and the apparent danger of defilement in dental facilities. RESULTS: Coronavirus management in dental clinics differs regarding adherence to the rules. An aggregate of 750 respondents finished the form, out of which 686 (91.46%) complete reactions were incorporated. The majority of the respondents concurred on inquiries regarding the knowledge, practice, and mentality of dental specialists toward the COVID-19 pandemic. CONCLUSION: The feedback of most dental specialists with respect to the readiness and view of disease control measures against the COVID-19 pandemic was positive. Dental facilities need to adhere more to the central and state government suggestions in alertness of their facilities or by tutoring their dental specialists and staff.
RESUMO
AIMS: The aim of the study was to assess the correlation between body mass index (BMI) and dental caries of 13-15-years-old school children in urban Bangalore and to compare the correlation between BMI and dental decay amongst government and private school children of age group 13-15 years in Bangalore city. SUBJECTS AND METHODS: A total of 660 students 13-15 years old were inducted in the study. According to these, 330 students from government schools and 330 students from private schools were examined. A specially designed structured questionnaire was used for compilation of data in the survey. BMI for age percentiles was deducted by weight in kilogram divided by height in meter square. RESULTS: Overall a positive correlation was found between Decayed, Missing, and Filled Teeth DMFT and BMI. In government schools, Overweight children had more mean DMFT (1.43) than other BMI categories while in Private schools, At risk of overweight children had more mean DMFT (1.4) than other category of BMI children. CONCLUSIONS: A positive correlation was found between DMFT and BMI. In government schools, Overweight children had more mean DMFT than other BMI category while in Private schools, At risk of overweight children had more mean DMFT than other category children.
RESUMO
BACKGROUND: Many of the contents of cigarette smoke are genotoxic in nature, and consequently, cytogenetic injury seems to be a trustworthy biomarker for deciding the influence of exposure to chromosome damaging agents in smoke. The cytokinesis-block micronucleus assay (CBMN assay) has been proven to be an effectual tool for the study of micronuclei (MN) that will help in estimating the genotoxicity in tobacco users alone which will further help in early cancer detection. OBJECTIVE: The objective is to find out whether there is pronounced contrast in genotoxicity between tobacco users and nonusers by determining MN number in peripheral blood lymphocytes using CBMN assay. METHODOLOGY: MN frequency in peripheral blood lymphocytes was estimated in 5 ml of fresh blood obtained from sixty individuals using tobacco either smoking, chewing, or combination of both and also from thirty individuals with no habit of tobacco use. All were in the age group of 20-40 years. RESULTS: There was a significant increase in genotoxicity in tobacco users when compared to that of nontobacco users. A positive correlation was also obtained between smoking index and MN frequency in the study. CONCLUSION: Approximation of frequency of MN by CBMN assay can be used to evaluate the genotoxicity present in blood and helps in identifying tobacco users who are at a high risk for the presence of cancer even before the appearance of clinical changes.
