義歯洗浄効果の臨床的観察 義歯床下粘膜の色調変化

Abstract

Recently, denture stomatitis was found in the oral mucosa of most denture wearers. It is generally accepted that the significant cause of denture stomatitis areinfection with Candida albicans. Dentists indicate that the denture plaque with Candida albicans is removed from denture surface by both mechanical denture cleaning and chemical denture cleaning. The color in the oral mucosa depends on the infection such as gingivitis and denture stomatitis.The purpose of this study is to examine the effect of the denture cleaner on the oral mucosa in the Candida-induced denture stomatitis by the change of the color in the oral mucosa.The results were as follows:1. The denture stomatitis became well after chemical denture cleaner was used. Especially, the infection at the posterior ofpalate were not found.2. The infection region have 2.8 R-5.1R in Hue, 5.7-6.1 in Chroma, 6.8-7.7 in Value. On the contrary, the non-infection region have3.8R-7.5 R in Hue, 6.4-6.9 in Chroma, 4.0-6.4 in Value.3. The color differencebetween the denture-bearing mucosa when no chemical denture cleaner was used andthat when denture cleaner was used, provided a method for estimating the effect of the denture cleaner. The greater color difference were found at the palate.
