口泰含漱液对控制菌斑和牙龈炎的疗效分析

本研究采用双盲随机对照法观察口泰含液对牙龈炎及控制菌斑的疗效。结果显示：实验组的牙龈指数,龈沟出血指数及菌斑指数以在含漱５天后均有明显的改善,且与对照组的比较也有明显的差异。     

Antibacterials as anti-inflammatory agents: Dual action agents for oral health

Background Inflammatory processes with a range of specialized cells and biochemical mediators form a complex network of inter-related signal transducing pathways that relay information to preserve normal functions. Advances in molecular analyses of the information relay pathways for their constituents and principal ligands along with mechanisms utilized by the host for microbial recognition have stimulated interest in therapeutic agents with dual functionalities i.e. antibacterial and anti-inflammatory effects. Aim This review examines clinically tested agents for oral health applications with both antimicrobial and anti-inflammatory effects to include antibiotics, antimicrobials and phenolics. Results Bis-phenols such as triclosan, representing a unique dual functional therapeutic for routine oral hygiene, with its demonstrated clinical effects on inhibiting the dental plaque biofilm, reducing inflammation (gingivitis) and subsequent periodontitis is described. Cyclines, comprising another class of approved anti-inflammatory agents used at the patient level for oral health is discussed. Dual active agents in current clinical practice for systemic conditions are highlighted to summarize the clinical validity of dual function agents as an emerging therapeutic strategy. Conclusions Clinical studies demonstrate therapeutic benefits of agents with dual functionality with their effects on microorganisms and the concomitant host inflammatory response. Advances in microbial pathogenesis and resultant inflammation will facilitate progress in this emerging area poised to be a significant milestone for dental therapeutics     

牙周微生态与龈沟液pH关系初探

目的：测定和分析健康和病变牙周部位的龈沟液ｐＨ差别。方法：牙周炎、牙龈炎和牙周健康者各１０例,用ｐＨ５５－９０试纸测定龈沟ｐＨ,分析与牙周袋（龈沟）深度和龈下厌氧菌丛的关系。结果：牙周炎组龈沟液ｐＨ普遍较牙龈炎组和牙周健康组高,其ｐＨ均数和标准差为８１０±０５７,牙龈炎组为７１９±０４５,牙周健康组为７１５±０５３,组间有非常显著意义差别（Ｐ＜００１）,其龈沟液ｐＨ与牙周袋深度、龈下菌斑厌氧菌总数呈正相关（Ｐ＜００５）;而牙龈炎组ｐＨ与健康组无显著意义差别（Ｐ＞００５）。结论：龈沟液ｐＨ是反映局部牙周微生态状况的一较好的客观参数,其变化的临床意义值得进一步研究。     

脉冲式冲牙器预防正畸患者牙龈炎的纵向对比研究

目的:正畸患者口腔内环境往往会受到多种不良影响,造成大量微生物种群定植于牙龈周围,并形成牙菌斑改变牙周组织的形态和结构,对正畸效果及疗程产生较大不利因素,如何采用合理干预措施降低口腔正畸患者牙菌斑和牙龈炎的发生率,成为正畸是否成功的关键因素之一。本研究旨在探讨脉冲式冲牙器对正畸患者牙菌斑及牙龈炎症的影响。方法:以82例青少年正畸患者及健康志愿者为研究对象,将正畸患者随机分为研究组(41例)和对照组(41例);于正畸后30天后对患者进行口腔卫生宣教及日常刷牙方法系统培训,研究组正畸患者采用脉冲式冲牙器;于干预前后评价牙龈指数(gingival index,GI)和Quigley-Hein菌斑指数(plaque index,PI)。结果:在干预前,志愿者与正畸30天患者均存在不同程度口腔卫生问题,正畸患者GI及PI等指数明显高于健康人群,差异具有统计学意义(P0.05);经过一定周期的干预,两组正畸患者的GI均有不同程度的改善,但以研究组患者效果更为明显,差异具有统计学意义(P0.05)。结论:脉冲式冲牙器能够产生超细高压脉冲水柱,可以在正畸治疗期间有效提高菌斑清除率,减缓牙龈炎的进程,不同程度改善正畸患者口腔卫生,有助于提高正畸治疗效果。     

西帕依固龈液联合西吡氯铵治疗牙龈炎的疗效分析

目的:探讨西帕依固龈液联合西吡氯铵治疗牙龈炎的临床疗效。方法:选择我院于2013年10月-2015年2月收治的130例牙龈炎患者,将其随机分成实验组和对照组各65例,对照组给予西吡氯铵治疗,实验组给予西帕依固龈液联合西吡氯铵治疗,比较两组患者的菌斑指数(PLI)、牙龈指数(GI)、龈沟出血指数(SBI)以及治疗疗效。结果:治疗8天后,实验组和对照组患者的治疗总有效率分别为96.92%和81.54%,组间比较差异具有统计学意义(P0.05)。两组患者治疗前PLI、GI、SBI比较无显著差异(P0.05);治疗后,两组患者各项指标均较治疗前有所改善,与各自治疗前比较差异具有统计学意义(P0.05),但两组治疗后的指标差异无统计学意义(P0.05)。两组患者不良反应的发生率分别为10.77%和9.23%,差异无统计学意义(x~2=0.0855,P0.05)。结论:西帕依固龈液与西吡氯铵联合使用治疗牙龈炎具有确切的疗效,同时具有较高的安全性。
