Background:Gingival changes during pregnancy have been well-documented. The prevalence of gingivitis in pregnant women has reportedly ranged from 30% to 100%. Increase in both the rate of estrogen metabolism and synthesis of prostaglandins by the gingiva contributed to the gingival changes observed during pregnancy. In effect increased prevalence of dental caries, gingivitis, periodontitis and tooth mobility may be encountered in pregnancy.Aim:The purpose of the study was to determine the association of some variables and the periodontal status in a sample of pregnant women attending the Ante Natal Clinic (ANC) of Lagos State University Teaching Hospital (LASUTH), Ikeja, Lagos.Subjects and Methods:Women at various stages of pregnancy, attending the ANC of LASUTH, constituted the target population. The questionnaire was administered on each patient followed by dental examinations. Periodontal status was assessed using the community periodontal index (CPI) of treatment needs. Oral hygiene status was evaluated according to Green and Vermilion simplified oral hygiene index (OHI-S).Results:The association between the CPI scores; OHI-S scores and variables such as trimester and dental visits were statistically significant.Conclusion:This study indicated that the gestational age of pregnancy and dental visits have a definite impact on the periodontal status. Oral health education should be included as an integral part of antenatal care to increase the women awareness. This would improve the mothers’ dental care-seeking behavior.
Amalgam is the cheapest and the most widely used intra-coronal posterior restorative material in the world.Therefore, the teaching, learning and practice of conservative amalgam cavity preparations cannot be ignored by any dental school. Since the introduction of the principles and methods of cavity preparation by G.V Black in 1908, there have been a series of modifications in terms of designs and the underlining principles.The “extension for prevention” dogma by G.V Black had been jettisoned while the modern concept of conservatism or minimal cavity preparation has been well embraced by dental practitioners. However, there are some limitations in clinical teaching of conservative amalgam cavity preparation which include late patient presentation with large carious lesions, lack of appropriate conservative instruments and restorative materials. This article discusses limitations in teaching, learning and practice of conservative amalgam cavity preparation in the developing countries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
