Background: The bone density of hard palate is key factor for success of palatal mini-implant. Smoking is an important determinant of osteoporosis.
Materials and method: Sixty males were selected with age range 20-39 years and divided into two groups according to smoking; smokers group (30), and nonsmokers (control) group (30). The measurements of hard palate bone density by HU (unit used to measure radiodensity of bone on CT scan) were made at 20 sites at the intersection of five anterioposterior and four mediolateral reference lines using Philips, Brilliancetm, 64-multislice computed tomography scanner software.
Results: The results that were obtained showed that there was a statistically significant difference between the two groups in bone density at most areas of hard palate. The comparison between the two groups in the overall cortical bone density showed a highly statistically significant difference. The comparison between the two groups in the overall cancellous bone density showed a statistically significant difference.
Conclusion: Hard palate bone density decreased by smoking. In spite that, orthodontic mini-implants can be safely used for smoker persons in hard palate.
