The effect of frequency of toothbrushing on oral health of 14-16 year olds.
ABSTRACT The aim of the present study was to evaluate the impact of toothbrushing frequency on dental plaque, caries and periodontal condition in 14-16 year old students. A total of 2083 students selected from 20 schools enrolling 8th and 9th grades were investigated by a questionnaire and a clinical examination. All participants were examined for oral hygiene, dental caries and periodontal condition using Silness & Löe plaque index (Pl.l), decayed, missing and filled teeth/surfaces (DMFT/S) indices and Community Periodontal Index of Treatment Needs (CPITN), respectively. It was revealed that about 49 per cent of males and 89 per cent of the females reported to brush their teeth on a regular basis. Such differences in toothbrushing frequency between the sexes were statistically significant (P = 0.0001). The mean (Pl.l) scores were lower in those who brushed than those who did not brush their teeth, with a significantly lower scores in females than in males (P = 0.0001). There were slight but nonsignificant differences in caries experience (MFT/S) amongst males and females as related to toothbrushing frequency (P = 0.121, 0.208 respectively). While bleeding on probing (43.0 per cent) was most prevalent in students who did not brush. Calculus scores were similar in all groups. The occurrence of shallow and deep pockets in students who brushed or didn't brush their teeth were minimal (6.6-8.4 per cent). The oral health status among those who did not brush or brushed their teeth on regular or irregular basis was found to be poor and slightly varied. Therefore, more emphasis should be placed on proper oral hygiene. Also, implementation of school based oral health promotion and prevention programs is urgently needed.

ABSTRACT: Objectives. The aim of this study was to evaluate levels of oral health knowledge of periodontal disease among nondental university students. Materials and Methods. Two hundred and fifty university students (mean age 20.1 years ± 2.5) were recruited into this study. The participants completed a structured questionnaire during a personal interview. The questionnaire consisted of items to assess participants' personal data (age, gender, level of study, and specialty) and oral heath knowledge related to periodontal disease. Statistical significance was based on probability values of less than 0.05. Results. Participants showed poor knowledge of causes, signs, symptoms, and preventive measures of gum disease. The level of study had no relationship with students' knowledge of the initiating factors of periodontal disease (P < 0.05), but had a significant relationship with the knowledge of periodontal disease's signs, preventive measures, and relations to general health and systemic disease (P < 0.05). Students from scientific disciplines had more knowledge of periodontal disease's causes, preventive measures, and relations to general health and systemic disease (P < 0.05) than those from humanity disciplines. Conclusions. There were significant differences in oral health knowledge regarding periodontal disease between students from different levels of studies and different disciplines.International Journal of Dentistry 01/2013; 2013:647397.
