可摘義齒菌斑影響因素的Logistic回歸分析

[摘要]目的：了解可摘義齒的菌斑覆蓋狀況并探討其影響因素，為可摘義齒的菌斑控制提供指導(dǎo)。方法：隨機(jī)抽取226例可摘義齒佩戴者為對(duì)象，進(jìn)行問卷調(diào)查和義齒臨床檢查，對(duì)調(diào)查結(jié)果進(jìn)行單因素分析及多因素Logistic回歸分析。結(jié)果：?jiǎn)我蛩胤治鲲@示，可摘義齒菌斑各影響因素中，義齒的戴用時(shí)間、清潔方式、夜間保存方式、表面有無磨痕等均對(duì)義齒的菌斑評(píng)分有影響，差異有統(tǒng)計(jì)學(xué)意義（P＜0.05）；多因素Logistic回歸分析顯示，各影響因素中，義齒清潔方式和戴用時(shí)間是義齒菌斑評(píng)分的主要影響因素。結(jié)論：使用高效清潔方式如義齒清潔劑的義齒菌斑輕于其他方式組，義齒戴用時(shí)間長(zhǎng)的人群義齒菌斑重于戴用時(shí)間短者。故建議義齒戴用者采用義齒清潔劑這種高效、便捷的清潔方式來維護(hù)義齒的清潔衛(wèi)生，同時(shí)可以對(duì)義齒進(jìn)行定期拋光，并在使用一定年限后更換或制作新義齒來抑制菌斑的產(chǎn)生。

Abstract: Objective To guide patients to control their dentures plaque by comprehending the plaque coverage of removable partial denture and exploring its influencing factors. Methods A questionnaire survey and clinical examination of 226 patients with removable dentures were randomly carried out，and multifactorial logistic regression analysis followed by monofactorial analysis was applied to analyze the survey results. Results According to monofactorial analysis involved the influencing factors of removable dentures，wearing time，cleaning methods，methods of denture conservation for night and denture base abrasion all have significant difference(P＜0.05). Logistic regression analysis displays that cleaning methods and wearing time are main influencing factors among various influencing factors. Conclusion The plaque of removable denture with an efficient cleaning method such as denture cleanser is significantly less than its control methods;the plaque of denture of longer wearing time is significantly more than that of shorter wearing time.Accordingly，suggestions such as using efficient denture cleanser to clean dentures，polishing denture periodically，replacing old dentures with new ones after years usage and so on are given to patients to inhibit plaque of their dentures.

隨著我國(guó)逐漸進(jìn)入老齡化社會(huì)階段，由齲病、牙周病老年退行性變等多種原因造成的牙列缺損或缺失的人群越來越多，而可摘局部義齒和全口義齒由于價(jià)格低廉、適應(yīng)證廣泛等原因，仍是目前國(guó)內(nèi)的主要修復(fù)治療方法之一。可摘義齒在使用過程中，因患者的生活習(xí)慣、清潔方式和戴用時(shí)間等原因，常常出現(xiàn)義齒表面菌斑堆積、色素沉著等問題，不僅影響美觀，還可能對(duì)患者的口腔局部和全身健康造成危害。……
