Aim: To investigate effects of smoking on periodontal tissue and the occurrence of periodontal disease in the population of North Herzegovina.
Methods: The study included 800 persons of 20-49 years of age (400 smokers and 400 non-smokers), inhabitants of Prozor-Rama Municipality, Bosnia and Herzegovina. Periodontal condition assessment was made by the Community Periodontal Index of Treatment Needs index (CPITN) at representative teeth: 16, 17, 21, 26, 27, 36, 37, 31, 46, and 47.Statistically significant difference between non-smokers and smokers was tested by χ2 test with the level of significance set at p=0.05.
Results: The prevalence of healthy periodontal tissues was lower in smokers than in non-smokers, 25 (6.3%)and 36 (9%), respectively. The prevalence of gingival bleeding, calculus, shallow and deep periodontal pockets was higher in smokers than in non-smokers, although it was not significant. There was a risk between occurrence of deep periodontal pockets and smoking (RR=2). A total of 64 (8%)participants neededonly instructions on proper oral hygiene, 654 (81.8%) prophylaxis and initial treatment,while 21 (2.6%) needed complex periodontal treatment.
Conclusion: Obtained results indicate a high need of preventive measures and the improvement of oral health in the population of North Herzegovina.
