Control of denture plaque accumulation is essential to obtain and maintain a healthy oral mucosa in denture wearers. The present study was designed to study the effect on denture plaque accumulation and denture stomatitis of coating the fitting denture surface by a glaze. Twenty-one subjects wearing complete dentures participated in the study. Glazing of the denture surface was performed using a Perma Cure System. Plaque accumulation was studied clinically and using a semiquantitative microbiologic technique. Plaque accumulation on the glazed and the non-glazed halves of the fitting denture surface was compared after 1 wk. There was significantly less plaque on the glazed half of the denture (P less than 0.001), and the calculated number of CFU of bacteria/cm2 was significantly lower from the test area of the glazed half than from the test area of the non-glazed half of the denture (P less than 0.001). When the patients were re-examined 1 month after the entire fitting denture surface had been glazed plaque scores, yeast scores and number of CFU of bacteria/cm2 were not significantly different from those observed before glazing. There was a reduction of the erythema of the palatal mucosa in 14/19 patients with denture-induced stomatitis. The study indicates that coating of the fitting denture surface by a glaze may be a means to improve denture cleanliness; however, the present glazing system should be further developed to produce a more uniform glazing.
控制义齿菌斑堆积对于义齿佩戴者获得并维持健康的口腔黏膜至关重要。本研究旨在探讨通过在义齿贴合面涂覆釉质对义齿菌斑堆积和义齿性口炎的影响。21名佩戴全口义齿的受试者参与了本研究。使用Perma Cure系统对义齿表面进行上釉处理。通过临床检查和半定量微生物学技术研究菌斑堆积情况。1周后比较义齿贴合面有釉质和无釉质部分的菌斑堆积情况。义齿有釉质的一半表面菌斑明显较少（P<0.001），且釉质一半测试区域每平方厘米细菌的CFU计算数量显著低于义齿无釉质一半的测试区域（P<0.001）。当整个义齿贴合面都进行上釉处理1个月后对患者进行复查时，菌斑评分、酵母菌评分以及每平方厘米细菌的CFU数量与上釉前观察到的情况无显著差异。19名患有义齿性口炎的患者中有14名腭黏膜红斑减轻。该研究表明，在义齿贴合面涂覆釉质可能是改善义齿清洁度的一种方法；然而，目前的上釉系统应进一步改进以实现更均匀的上釉效果。
