Periapical bone healing in smokers and non-smokers after non-surgical endodontic treatment-a prospective study

Aim: To compare the healing of periapical bone in smokers and non-smokers following non- surgical endodontic treatment in patients with apical periodontitis (AP). Materials and methods: This prospective study involved sixty-six adult patients with AP diagnosis who were endodontically treated at Rijeka University Dental clinic (smokers n=33, non-smokers n=33). Data regarding smoking status were obtained from a self- administered questionnaire. The participants were matched according to gender and age. Healing of AP was determined utilizing periapical index (PAI) and dichotomized as healed (<3) and not healed (≥3) at the six and twelve months follow up. Frequency distribution and chi-square test were used to evaluate PAI score change at baseline and subsequent intervals. Results: There were 46 women and 20 men included in the study at baseline and six months interval. The mean age of participants was 35.4 years with a range of 19 to 65 years. In the non-smoker group, 24.2% (n=8) of AP have healed at six months follow up, and 42.4% (n=14) of AP in the smoker group. There were forty-eight participants included in the study after 12 months, 32 women and 16 men. In the non-smoker group 75% (n=18) of AP were healed in comparison to 70.8% (n=17) in the smoker group. The analysis showed no statistically significant differences in healing rate between two groups after six months (P = 0.1917) or after 12 months (P=0.821). Conclusion: The present data demonstrate no difference in healing rate between smokers and non-smokers.
