种植覆盖义齿在老年人牙列缺失修复中的应用

老年人牙列缺失是口腔修复治疗中的难点之一。义齿固位差 ,功能与美观受损及某些心理因素的影响使部分患者无法接受常规的全口义齿修复〔1〕。而依靠种植体、牙槽骨和粘膜共同支持的全口种植覆盖义齿则为解决这一难题提供了较理想的方法〔2〕。　　一、种植覆盖义齿的种类　　 1.杆卡固位式种植覆盖义齿 :至少植入 2个种植体 ,在2个种植体基台上做一连接杆并固定在基台上 ,然后在义齿基托组织面安装弹性固位卡 ,使之卡在连接杆上。连接杆有直杆、弧形杆、有角度杆等 ;横断面有矩形、圆形或卵圆形 ,前者称刚性附着 ,后者称弹性附着〔3〕。　…

The strength of age effect on tooth loss and periodontal condition in Korean elderly

Aging is a well-known risk factor associated with oral diseases. The aim of this cross-sectional study was to compare tooth loss and periodontal health between the relatively young elderly (65-74 years) and the old elderly (≥75 years) and to investigate the strength of the age effect on oral health status in the Korean elderly. Study population 65 years of age or older were selected from the participants of the Korean National Oral Health Survey (2006) (n = 1193). Oral examination was conducted by eight dentists trained in the World Health Organization (WHO) recommended examination procedure. The chi-square test, multiple regression analyses and multinomial logistic regression analyses were performed using SAS 9.1.3. The oral health status including decayed, missing, and filled teeth (DMFT), missing teeth, and residual teeth significantly differed between the young elderly and the old elderly (p < 0.01). Moreover, the regression coefficients of tooth loss linearly increased across different age groups (5-year intervals, starting at age 65 years) (p < 0.05). However, the odds ratios of periodontal health did not significantly differ across 5-year interval age groups. The findings that age and the number of missing teeth are significantly and linearly related could contribute to the development of oral health care and promotion programs for the elderly tailored to their own age.     

Investigating tooth loss and associated factors among older Taiwanese adults

The aim of this study was to evaluate factors associated with tooth loss in older Taiwanese adults with different numbers of remaining teeth. This study evaluated oral health status and tooth loss among 2286 adults aged over 65. Subjects were classified according to number of teeth (Group 1 <20 teeth vs. Group 2 ≥20 teeth). Tooth loss and oral health data were collected from the National Health Interview Survey (NHIS), compared between groups and analyzed by multivariate modeling. Group 1 subjects were older and had more partial dentures. Tooth loss was associated with self-limited food choices due to oral health status, and malnutrition. Tooth loss in Group 2 subjects was significantly associated with lower mental status. Tooth loss may predict cognitive status (odds ratio (OR) 1.30) and physical-disability (OR 1.79). Our results suggested that tooth loss was associated with age, more partial dentures, self-limited food choices, malnutrition, and lower mental and cognitive status and physical disability.     

2型糖尿病患者缺牙及义齿修复相关因素临床研究

目的：探讨2型糖尿病患者缺牙及义齿修复的相关因素。方法选取126例研究对象,其中2型糖尿病63例作为糖尿病组,非糖尿病人63例作为对照组,比较两组缺牙数、牙周病牙数及龋病牙数等相关指标的差异。调查两组牙列缺损及义齿修复情况,分析糖尿病人缺牙的相关因素。结果糖尿病组缺牙数、牙周病牙数及复杂牙列缺损病例数均较对照组增多,差异有统计学意义（ P＜0.05）。 Logistic多元逐步回归分析表明,两组在牙周病牙数、复杂牙列缺损病例数及定期口腔健康检查例数方面的差异也具有统计学意义（ P＜0.05）。结论糖尿病组缺牙数、牙周病牙数及复杂牙列缺损病例数较对照组明显增多,多因素分析结果表明牙周病牙数、复杂牙列缺损例数及定期口腔健康检查与糖尿病缺牙关联密切。     

中老年人牙楔状缺损程度指标的研究

目的确定楔状缺损侧影深度指标对实际缺损程度的代表性。方法选取69副牙石膏模型上的193颗上颌患楔状缺损牙齿,游标卡尺测量牙颈部缺损的侧影深度、宽度和高度,计算测量体积;其中9颗牙齿楔状缺损用复合树脂修复,取出修复体称重,换算缺损实际体积。结果以实际体积为Y,测量体积为X,建立线性回归方程:Y=0．4735+2．5948X;确定系数R2=0．9472,回归系数经检验F=125．57,P<0．01。表明该回归方程成立,实际体积与测量体积的相关性好。建立线性回归方程:实际体积(缺损)=0．4735+2．5948X侧影深度×宽度×高度(缺损)／6。楔状缺损侧影深度与实际体积有显著相关关系。结论楔状缺损一维测度可以代表牙颈部缺损程度。     

成年人及老年人龋病状况十年纵向观察

目的 观察成年人与老年人龋病的自然发展过程以及与牙齿缺失的关系,为该病的防治提供依据。方法 1984年对20岁以上成年人587人的口腔状况进行了检查,1994年随访复查440人,2次检查由相同的检查人员完成,对龋病的有关资料进行分析。结果 各年龄组在10年内均有新龋损形成,新增龋补牙数(DFT值)随年龄增长而增加。10年间所观察人群共丧失2114颗牙齿,占初查时存留牙齿总数的18．9％。初查时无龋牙10年后缺失10．8％,釉质龋牙缺失17．9％,而牙本质深龋牙齿的缺失高达76．0％。结论 龋病是影响成年人,特别是老年人健康的主要疾病,牙齿的缺失与初查时龋病的严重程度有关。如不积极改善口腔卫生和(或)进行干预,因龋病而丧失的牙齿数将随年龄增长而增加,从而影响生活质量。     

Prevalence of tooth loss and dental service use in older Mexican Americans

OBJECTIVES: To describe the prevalence of tooth loss, to examine risk factors for having fewer teeth or no teeth, and to describe the use of dental services in an older Mexican-American population. DESIGN: Data from the baseline phase of the Hispanic Established Population for the Epidemiological Study of the Elderly survey conducted from 1993 to 1994, a cross-sectional survey of older Mexican Americans. SETTING: Five southwestern states: Texas, California, Arizona, New Mexico, and Colorado. PARTICIPANTS: 3,050 noninstitutionalized Mexican Americans age 65 to 99. RESULTS: Twenty-seven percent of the sample was completely edentulous and 22% reported visiting or speaking with a dental care professional in the preceding year. Logistic regression analyses showed that being older or being female was significantly associated with tooth loss, adjusting for education, income, smoking status, and diabetes mellitus. Current smokers (odds ratio (OR) = 1.69; 95% CI = 1.31-2.20) and diabetics (OR = 1.53; 95% CI = 1.27-1.84) were more at risk for tooth loss, as were persons of lower socioeconomic status. CONCLUSIONS: The prevalence of tooth loss and use of dental services in this population of older Mexican Americans is lower than what has been previously found among older people in the general population.
