【摘要】：背景:研究表明,義齒性口炎的發(fā)生和嚴(yán)重程度與義齒清洗方法和戴用時(shí)間有密切關(guān)系,因此研究清潔劑對(duì)義齒材料顏色、粗糙度的影響有重要意義。目的:以浸泡法觀察4種不同清潔劑對(duì)義齒材料顏色和粗糙度的影響。方法:取熱凝樹(shù)脂材料、隱形義齒材料試件各25件,拋光后各分5組,分別浸泡于次氯酸鈉清潔劑、Efferdent清潔劑、Polident partial清潔劑、Polident overnight清潔劑和清水中,浸泡90次,檢測(cè)浸泡前及浸泡30,60,90次后的試件色差值及粗糙度。結(jié)果與結(jié)論:(1)4種清潔劑對(duì)隱形義齒材料顏色、粗糙度的影響大于熱凝樹(shù)脂材料;(2)隨著清潔劑浸泡時(shí)間的延長(zhǎng),兩種材料的色差值逐漸增大;熱凝樹(shù)脂材料及隱形義齒材料在不同溶液中浸泡90次后,次氯酸鈉清潔劑組色差值最大,然后依次為Efferdent清潔劑組、Polident overnight清潔劑組,Polident partial清潔劑組色差值最小,接近于清水組;(3)隨著清潔劑浸泡時(shí)間的延長(zhǎng),兩種材料的粗糙度值逐漸增大;熱凝樹(shù)脂材料及隱形義齒材料在不同溶液中浸泡90次后,次氯酸鈉清潔劑組粗糙度值最大,然后依次為Efferdent清潔劑組、Polident overnight清潔劑組,Polident partial清潔劑組粗糙度最小,接近于清水組;(4)結(jié)果表明,義齒清潔劑均能引起熱凝樹(shù)脂材料、隱形義齒材料顏色及粗糙度的變化,次氯酸鈉、Efferdent、Polident overnight清潔劑的影響較強(qiáng),Polident partial清潔劑的影響較弱。
[Abstract]:Background: studies have shown that the incidence and severity of denture stomatitis is closely related to the method of denture cleaning and wearing time. Objective: to observe the effect of four kinds of cleaning agents on the color and roughness of denture materials by immersion method. Soaking in sodium hypochlorite detergent, Efferdent partial cleaner, Polident overnight cleaner and clean water for 90 times, The color difference and roughness of the samples were measured before immersion and 90 times after immersion. Results and conclusion the effect of 4 kinds of cleaning agents on the color and roughness of invisible denture materials was greater than that of thermosetting resin materials.) with the prolongation of soaking time of cleaning agent, the effect of four kinds of detergents on the color of invisible denture materials was greater than that of thermosetting resin materials. The color difference value of the two materials increased gradually, the color difference value of sodium hypochlorite cleaning agent group was the largest after 90 times immersion of thermosetting resin material and invisible denture material in different solution. Then the color difference value of the Efferdent overnight detergent group was the smallest, close to that of the clean water group.) with the prolongation of soaking time, the roughness value of the two kinds of materials increased gradually. After 90 times immersion in different solution, the roughness of sodium hypochlorite detergent group was the highest, and the roughness of Efferdent overnight cleaner group was the lowest. The results showed that denture cleaners could cause the changes of color and roughness of the materials, and the effect of sodium hypochlorite Efferdentate Polident overnight cleaners was stronger than that of Polident partial cleaners.
