Predicting oral hygiene practices through health behavior, perceived stress and self-efficacy in undergraduate dental students of Pakistan: a national survey.

BACKGROUND: Dental students face the rigorous demands of coursework, which can lead to feelings of inadequacy and stress. These pressures can negatively influence self-efficacy and cause neglect in practicing healthy behaviors that encompass oral health. Identifying the associations of these variables with oral hygiene practices can help in the formulation of interventions tailored toward supporting young students. Therefore, this study aimed to investigate the impact of health behaviors, perceived stress and self-efficacy on oral hygiene practices among undergraduate dental students in Pakistan. METHODS: A national online survey was carried out among 904 students across the dental colleges of Pakistan. The survey assessed general health behaviors such as tobacco use, sleep, and exercise, among other demographic variables. Perceived stress was evaluated via the Perceived Stress Scale (PSS-10), and self-efficacy was evaluated via the General Self-Efficacy Scale (GSES). Twice daily brushing, brushing for 2 min, and changing toothbrushes after 3 months informed oral hygiene practice of the participants. RESULTS: The students experienced moderate perceived stress (20.82 ± 5.92) and high self-efficacy (29.19 ± 5.43). The majority of participants were in their third year (31.9%), were female (65.9%), and resided in home during their studies (64.4%). Perceived stress was observed to have no significant effect on the oral practice of participants. Female gender, non tobacco user, regular exercise, frequent dental visits and higher self-efficacy were associated with good oral hygiene practices. CONCLUSIONS: The results highlight the importance of addressing stress, enhancing self-efficacy and encouraging healthy behaviors among dental students to improve their oral health, which could be reflected in their professional practice and personal well-being. This study contributes to the understanding of behavioral determinants and emphasizes the need for supportive measures to foster better health behaviors in future dental professionals.

Human papilloma virus and oral lesions in gutka eating subjects in Karachi.

OBJECTIVE: To determine the frequency of HPV in eaters of Gutka (betel, areca, lime and tobacco concoction), presenting with oral lesions. STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: Ziauddin University Research Laboratory, from February to July 2010. METHODOLOGY: Subjects munching Gutka fulfilled the inclusion criteria. Samples were collected in the form of 20 - 40 ml oral rinse from 262 subjects who were habitual eaters of Gutka after an informed consent. Gentle brushings from the lesion were taken from subjects with the help of a brush at the other end of dental floss and the oral rinse was stored at 4°C until DNA extraction. DNA was extracted and PCR was performed using HPV consensus primers Gp5+/Gp6+. Oral cavity was examined for the presence of ulcer, trismus, sub-mucosal fibrosis, leukoplakia and/or warts. RESULTS: Out of 262 subjects, 42 were females and 220 males with an average age of 27± 10 years. HPV was positive in 47 subjects (17.9%). HPV frequency was 2.7% greater in chewers with more than 10 years of habit compared to less than 10 years. Examination of oral cavity showed 78% presenting with more than one complaint including oral ulcers (25%), rough mucosa (62%), sub-mucosal fibrosis (24%), leukoplakia (20%) and erythroplakia (10.6%). Highest frequency of HPV was observed in erythroplakia (25%). Association between presence of symptoms and HPV shows an ODDS RATIO: ad/bc= 4982/430=11.6. CONCLUSION: Oral lesions caused by constant exposure to Gutka are associated with high frequency of HPV infection, which may be a risk factor for squamous cell carcinoma of the oral cavity. People should be educated about the consequences of Gutka abuse.
