ABSTRACT
Introduction: Restoring a proximal lesion in primary tooth has met with many challenges which has led to evolution of many materials. An alternative to Glass Ionomer Cements which has fluoride releasing capacity, offers good bond strength and is esthetic have been long looked for. Aim: This study aimed to compare the clinical performance of GIC and Cention N in proximal restorations of primary molars. Materials and Methodology: A prospective study was conducted on 154 primary molars in patients aged between 5 and 8 years using a split-mouth design. Patients were divided into two groups. Control group restored with GIC and study group received Cention N. Both groups were assessed at baseline 3, 6 and 9 months according to Ryge criteria and data was statistically analysed using Fisher's Exact. Results: Statistically significant difference was found between GIC and Cention N restorations for color match at baseline and color stability at 3 months (P < 0.001), while the other parameters did not show any significant difference among the two restorative materials. Conclusion: Cention N can be used as a suitable alternative to GIC for restoring Class II restorations in primary molars.
ABSTRACT
Tooth wear is an ever increasing problem. However, literature on tooth wear prevalence is scarce. Therefore, the aim of the present study was to assess the prevalence and severity of tooth wear among 12 to 15 year old children of private schools of Farukhnagar block (Gurgaon) Haryana. Material and Methods: 973 school children in the age group of 12 to 15 year from the Gurgaon district were included in the study. All permanent teeth were examined by two trained calibrated examiners using CPITN probes in four surfaces, namely cervical (C), buccal (B), occlusal (O) or incisal (I) and palatal (P) or lingual (L) surface using Tooth Wear Index (TWI) . SPSS 19 was used for descriptive statistics and chi-square test. Results: A total of 26,230 teeth were examined. Overall prevalence of tooth wear was 29.7%. Most frequently affected teeth were the Incisors (15.4%), followed by the Molars (7.4%). Incisal/occlusal surface was the most commonly affected surface. All the tooth wear lesions observed were mostly confined to the enamel (76.4%). Boys had statistically significant higher tooth wear prevalence (16.2%) compared to girls (13.5%). Dental fluorosis determined higher tooth wear prevalence (61.5%). Conclusion: There is high prevalence of tooth wear among school children, and boys have more tooth wear compared to girls. Dental fluorosis is associated with high risk for tooth wear. Thus tooth wear poses a significant public health problem, and steps should be taken for early diagnosis, prevention and management...
O desgaste dos dentes é um problema crescente. No entanto, a literatura sobre a prevalência de desgaste dentário é escassa. Portanto, o objetivo do presente estudo foi avaliar a prevalência e a severidade do desgaste dentário entre as crianças de 12 a 15 anos de idade de escolas particulares de Farukhnagar (Gurgaon) Haryana. Material e métodos: 973 crianças em idade escolar na faixa etária de 12 a 15 anos do bairro de Gurgaon foram incluídas no estudo. Todos os dentes permanentes foram examinados por dois avaliadores treinados calibrados utilizando sondas CPITN em quatro superfícies [cervical (C), vestibular (B), oclusal (O) ou incisal (I), e palatina (P) ou lingual (L)] da superfície do dente por meio do Índice de Desgaste Dental (IDD). O SPSS 19 foi utilizado para a estatística descritiva e teste do qui-quadrado. Resultados: Um total de 26.230 dentes foi examinado. A prevalência de desgaste dentário foi de 29,7%. Os dentes mais afetados foram os incisivos (15,4%), seguidos pelo molares (7,4%). A superfície incisal/oclusal foi a mais comumente afetada. Todas as lesões de desgaste dos dentes observados estavam confinadas principalmente ao esmalte (76,4%). Os meninos apresentaram maior prevalência de desgaste dos dentes (16,2%) em comparação às meninas (13,5%). A fluorose dental determinou maior prevalência de desgaste dentário (61,5%). Conclusão: Há uma alta prevalência de desgaste dentário em escolares, e os meninos apresentam mais desgaste em comparação com as meninas. A fluorose dental é associada ao alto risco de desgaste dentário. Assim, o desgaste do dente representa um importante problema de saúde pública, devendo ser tomadas medidas para o diagnóstico precoce, a prevenção e o tratamento...
