Abstract

Background and Aims: Tobacco smoking is now recognized to be an important risk factor for the development and progression of periodontal disease. Nicotine, the major constituent of particulate phase of tobacco smoke, in addition to having its toxic systemic effects, is capable of causing local cytotoxicity. The typical characteristic of smoking-associated periodontal disease is the destruction of the supporting tissues of the teeth, with the ensuing clinical symptoms of bone loss, attachment loss, pocket formation, and eventually tooth loss. The mechanisms behind the destructive effects of smoking on the periodontal tissues, however, are not well understood. This study aimed to detect nicotine from the root surfaces of periodontally involved root surfaces and to compare the quantity of nicotine present on root-planed and non-root-planed surfaces of teeth from smokers. Materials and Methods: 25 periodontally involved extracted teeth were taken from 18 smoker patients. The roots were sectioned longitudinally and each root half was either root planed (group B) or left untreated (group A). Each root half was extracted for nicotine using methylene chloride technique, and quantified using high pressure liquid chromatography (HPLC). Statistical analysis: Nicotine concentrations were compared between the root planed ans the non root planed groups using paired t-test. Results: The results showed that nicotine could be detected from the root surface of periodontally involved teeth. The amount of nicotine present on non-root planed sections was statistically significantly higher than on treated sections. Conclusion: Nicotine is present on the periodonatally involved root surfaces of smoker patients and also its concentration can be significantly reduced by thorough root planning.
测定牙根刨除法去除吸烟者牙周病变牙齿中尼古丁的功效
背景和目的:吸烟现在被认为是牙周病发生和发展的一个重要危险因素。尼古丁是烟草烟雾颗粒相的主要成分,除了具有全身毒性作用外,还能引起局部细胞毒性。吸烟相关牙周病的典型特征是破坏牙齿的支撑组织,随之而来的临床症状是骨质流失、附着物丧失、牙袋形成,最终导致牙齿脱落。然而,吸烟对牙周组织的破坏性影响背后的机制尚不清楚。本研究旨在检测吸烟者牙周病牙根表面的尼古丁含量,并比较吸烟者牙根平面和非牙根平面的尼古丁含量。材料与方法:选取18例吸烟患者的25颗牙周病变拔牙。根纵切,每一半根刨平(B组)或不处理(A组)。每一半根用二氯甲烷技术提取尼古丁,并使用高压液相色谱(HPLC)定量。统计学分析:采用配对t检验比较刨根组和未刨根组的尼古丁浓度。结果:在患牙周牙根表面可检测到尼古丁。未刨根切片的尼古丁含量显著高于处理过的切片。结论:尼古丁存在于吸烟者患牙周病的牙根表面,通过彻底的牙根规划可显著降低其浓度。
