The Effect of Waterpipe Smoking on Periodontal Health.

PURPOSE: To determine the effect of waterpipe smoking on periodontal health. MATERIALS AND METHODS: The study included 190 participants who were categorised into four groups; cigarette smokers, waterpipe smokers, dual smokers and nonsmokers. Intraoral examination included plaque (PI), gingival (GI) and calculus (CI) indices, probing pocket depth (PPD), clinical attachment level (CAL) and bleeding on probing (BOP). RESULTS: The four groups differed significantly in the prevalence and extent of periodontal disease. Pairwise comparison tests showed that the means of percentages of sites with PPD > 3 mm, PPD > 4 mm, CAL > 1 mm and bleeding on probing were significantly higher among smoking groups compared to the nonsmoking group (p < 0.05). After adjusting for age, cigarette smokers (OR = 4.6), waterpipe smokers (OR = 4.3) and dual smokers (OR = 4.9) were significantly more likely to have periodontal disease compared to nonsmokers. When data were analysed according to the smoking method, no significant differences in the odds of periodontal disease were detected between different smoking groups (p > 0.05). CONCLUSION: Waterpipe tobacco smoking is not an alternative, safe way of smoking considering periodontal disease. Thus, global actions against waterpipe smoking are required.

Prevalence, social acceptance, and awareness of waterpipe smoking among dental university students: a cross sectional survey conducted in Jordan.

BACKGROUND: Waterpipe tobacco smoking is increasing in popularity especially among young adults. This spread could be related to limited knowledge of the negative health effects of waterpipe smoking. In this study, prevalence, social acceptance, and awareness of waterpipe smoking were examined among dental university students. METHODS: This is a cross-sectional survey study, where a self-administered questionnaire was completed by a sample of dental university students in Jordan. RESULTS: Students (n=547) reported current tobacco use of 54.3% for males versus 11.1% for females (P<0.005). Among current smokers, 3.5% used only cigarettes (22.0% males, 2.3% females), 12.6% used only waterpipe (36.6% males, 88.6% females), and 6.9% used both (41.5% males, 9.1% females). Approximately, 70% of males and 42.5% of females who used waterpipe reported smoking mostly at a café. Nearly half of the females reported that they smoke at home in the presence of parents. Among participants, 33.3% of males and 62.5% of females reported indifferent parents' reaction regarding their waterpipe smoking. Approximately one third of students agreed with the statement that waterpipe smoking is less harmful to oral health than cigarette smoking. About 50-70% of students agreed that waterpipe smoking causes halitosis, delays wound healing time, is associated with dental implant failure, and increases the risk of dental decay. CONCLUSIONS: In this sample, waterpipe tobacco smoking was more common than cigarette smoking among dental students, especially females. This could be an implication of social acceptance of waterpipe leading to its predominance, and thus, the gradual replacement of cigarette smoking with waterpipe smoking. Additionally, dental students' awareness about the harms of waterpipe is not optimal, and steps are needed to ensure providing such knowledge to students.
