ABSTRACT
Objective To investigate the negative effect of cigaratte smoking on periodontal theraphy. Mothods 84 patients with periodontopathy were selected and divided into two groups. The smoking group (group A) included 33 patients and the non-smoking group (group B) included 51 patients. All the patients received a systematic treatment. The effects of the treatment between different groups were compared through the debris index(DI),calculus index(CI),periodotal disease index(PDI) which were respectively recorded before and after treatment.Results After the treatment the DI,CI,PDI of two groups were all decreased; wheras compared with group A, every index of group B was significantly lower. Conclusions Somking seriously influences the effect of periodontal therapy. Therefore, to give up smoking is very important for preventing and treating periodontopathy.
ABSTRACT
Objective In order to explore the quantification of forensic medical determination to the tooth drop by boxing injury, we study the torensic clinical comparison between this kind of injury and periodontopathy, and study the characteristics of this kind of injury. Method Form the peri-odontopathy group by 65 cases of periodontopathy tooth drop by boxing injury and regular group by 65 cases of normal tooth drop by boxing injury, and analyze the data by statistical Chi-square test. Results Comparing to the regular group, the periodontopathy group has outstanding differences on age, the injury of buccal parenchyma, the type and number of tooth dropped, tooth broken and fracture of den to-alveolar. There is inverse ratio between the injury intensity and the determination of injury degree. Conclusion There is misunderstanding on determination of injury degree of periodontopathy tooth drop by boxing injury. It is necessary to use the injury degree of influence when we determine the above-mentioned injury.
