RESUMO
OBJECTIVE: The objective of the study was to obtain data on prevalence and severity of dental erosion among acid industry workers in Baddi (Himachal Pradesh). MATERIALS AND METHODS: A cross-sectional study was conducted among 800 battery industry workers. The demographic details were recorded on a prestructured pro forma. Type III examination was done. Dental erosion was recorded based on the index given by Bardsley (simplified scoring criteria for tooth wear index). Appropriate statistical tests were used to interpret the data. RESULTS: The prevalence of dental erosion was found to be 48.6%. Prevalence increased with the duration of employment. Dental erosion was most commonly found in the labial surfaces of maxillary anterior teeth. CONCLUSION: Erosion is a condition which is multifactorial and becomes more aggravating in the presence of acidic environment. Therefore, the workers working in such conditions should be more careful, and mandatory policies should also be followed by such industries to maintain the overall health of the workers.
RESUMO
BACKGROUND: The eventual sequel of dental caries is determined by the dynamic equilibrium between pathological factors which lead to demineralization and protective elements, which in turn leads to remineralization. Remineralization is the natural process for noncavitated demineralized lesions and relies on calcium and phosphate ions assisted by fluoride to rebuild a new surface on existing crystal remnants in subsurface lesions remaining after demineralization. Hence, the present study was designed to evaluate the efficacy of fluoride dentifrices in remineralizing artificial caries-like lesions in situ. MATERIALS AND METHODS: A double-blind, randomized study with an initial washout period of 7 days was carried out for 3 weeks. Twenty volunteers were enrolled, who wore the intraoral cariogenicity test appliance having enamel slabs incorporated into them, for 3 weeks. 10 participants were instructed to use Group A dentifrice (fluoride) and the other 10 Group B dentifrice (nonfluoride) for brushing their teeth. The enamel slabs were analyzed by surface microhardness testing and scanning electron microscopy (SEM) at 3 intervals. RESULTS: No significant differences was seen in the microhardness values recorded for Group A and Group B at baseline and after demineralization (P > 0.05); however Group B exhibited lesser microhardness compared to Group A, after intra-oral exposure (P < 0.05). In the SEM analysis, the Group A enamel surfaces had more regular and longer crystallites to those of the Group B. CONCLUSION: Fluoride dentifrices avert the decrease in enamel hardness and loss of minerals from the enamel surface to a large extent as compared to the nonfluoride dentifrices.
RESUMO
This paper reports the accidental injection of formalin into oral tissue space, in an 8-year old child resulting in chemical facial necrotizing cellulitis and its management. The common practice of keeping formalin in local anesthesia vials should be avoided by dental clinics, to prevent such unfortunate incidents.
RESUMO
Objetivo: Avaliar a saúde bucal de crianças que consomem refrigerantes e também conhecer as razões para o consumo excessivo dessas bebidas. Método: Um estudo de natureza transversal CAP (conhecimento, atitude e prática) com uma amostra de 200 crianças na faixa etária de 12-13 anos de idade foi realizado em Maharishi Markandeshwar International School, Mullana, Ambala, na Índia. Um questionário foi elaborado e distribuído para verificar as razões para o alto consumo de refrigerantes e os seus efeitos sobre a saúde bucal. Os dados coletados foram analisados estatisticamente. Resultados: Em média, as crianças na faixa etária de 12-13 anos consumiam entre 7 e 8 refrigerantes (latas - 250ml) por semana, ou seja, de 1500mL a 2000mL. Verificou-se que a gravidade da cárie dentária foi elevada quando os resultados foram comparados a crianças que não consumiram bebidas carbonatadas na mesma escola. Os resultados também confirmam que as crianças não estão conscientes dos efeitos nocivos dos refrigerantes sobre a saúde bucal. Conclusão: As crianças que consomem refrigerantes regularmente são mais propensas a cárie dentária.
Objective: To assess the oral health of children consuming carbonated beverages and also to ascertain the reasons for excess consumption of these beverages. Methods: A cross-sectional KAP (knowledge, attitude and practice) survey of 200 children in the age group of 12 - 13 years was carried out in Maharishi Markandeshwar International School, Mullana, Ambala, India. A questionnaire was designed and distributed to ascertain the reasons for high consumption of carbonated beverages and its effects if any on oral health. The data collected was analysed statistically. Results: The results of the study revealed that on an average, children in the age group of 12-13 years consumed 7-8 drinks (cans - 250ml) per week, i.e. 1500 - 2000 ml consumption. The severity of tooth decay was seen to be high, when the results were compared to those children who did not consume carbonated drinks in the same school. The findings also confirm that children are not aware of the detrimental effects of carbonated beverages on oral health. Conclusion: The children who consume carbonated drinks regularly are more prone to tooth decay.
