Dental Caries Experience and Oral Health Practice among 12-Years-Old Schoolchildren

Objectives: To assess the experience of dental caries and practice of oral health preventive measures. Methods: This was a secondary data study extracted from primary data through a cross-sectional study of a random sample of two hundred and forty-six 12 years-old Libyan schoolchildren (in 2019). Children underwent clinical examinations for dental caries experience. Then, they asked to complete a self-administrated questionnaire that designed to evaluate the oral health practices. The collected data were analysed using SPSS for Windows, version 25. The alpha value was 0.05. Results: The prevalence of dental caries, for the total sample, was 80.5% and the mean Decayed, Missing and Filled Teeth index (DMFT) was 2.4 (SD, 1.7). A clear gradient in the DMFT means with statistically significant was observed only across the categories of frequency of toothbrushing and frequency of sugary foods and drinks consumption in between meals. In addition, statistical significant was found for using fluoridated toothpaste. Conclusion: Dental caries in children aged 12 years old was prevalent in this study. The present survey provided an overview of practice of oral health preventive measures of participants, as the differences in these practices have influenced the DMFT values and provided knowledge about the disease experience.

Fluorine is the most reactive nonmetal and the most electronegative element. It almost never occurs in nature in its elemental state, it combines with all elements, except oxygen and the noble gases, to form fluorides. A human can obtain fluoride (F) from air, drinking water and food. The metabolism of F is constituted of the following processes; absorption: secretion: distribution: and excretion. A distinction is made between F that is ingested systemically and that is applied topically. Nevertheless, as seen by Murray and Naylor 1996, such distinctions are not helpful since all methods of F delivery can have both systemic and topical effects. F has made a great contribution in declining dental caries prevalence since the discovery of its anti-caries effect in 1938 by Dr Trendly Dean. Prolonged use of F at recommended levels does not produce harmful physiological effects in human. However, like every chemical, there are safe limits for F ingestion beyond which harmful effects occur. At excessive exposure levels, ingestion of F causes dental fluorosis, skeletal fluorosis, and manifestations such as gastrointestinal, neurological, and urinary problems. These effects can be classified as acute toxicity and chronic toxicity.
