Abstract Objective: The aim of this study was to compare the prevalence and size of periapical lesions among smokers and non-smokers using cone-beam computed tomography (CBCT).

Materials and methods: Retrievable CBCT datasets for 46 male patients !18 years during a con- secutive period from 2008 to 2016 were examined. The medical, smoking history and other clinical findings (signs of previous dental trauma; Decayed Missing Filled Teeth (DMFT) scores; the per- centage of root filled teeth; and oral hygiene status) were obtained. Periapical status of all included teeth was assessed by CBCT images. Statistical analysis was conducted using t-test, Pearson corre- lation and multiple regression.

Results: The prevalence of apical periodontitis was 13.93% in smokers and 14.26% in non- smokers with no significant difference (p = 0.936). The mean of the average size of lesions between the two groups were almost comparable, 3.50 mm in smokers and 2.89 mm in non-smokers 

(p = 0.567). Pearson correlation and multiple regression analysis showed that the percentage of lesion present and the average lesion size were not correlated to any independent variable.

Conclusions: While smoking is considered a risk factor for marginal periodontitis, there was no

difference between smokers and non-smokers in terms of apical periodontitis
