This study aimed to assess dentists' views of the utility of an unrestored shortened dental arch (SDA) compared to the utility of various prosthetic treatment options.
A total of 142 dentists working at four sites in Riyadh, Saudi Arabia, were interviewed and presented with 18 scenarios for patients of different ages with SDAs that lost molar teeth. Participants were asked to indicate on a standardized visual analog scale (VAS) how they would value the health of the patient's mouth if the SDAs were left unrestored or restored with five prosthetic dental restorations.
With a utility value of 0.0 representing the worst possible health state for a mouth and 1.0 representing the best, dentists' mean utility value for unrestored SDAs was 0.43 (standard deviation [SD] = 0.28). For implant-supported fixed dental prostheses (ISFDPs), cobalt-chromium removable partial dentures (RPDs), acrylic RPDs, cantilever conventional fixed dental prostheses (CFDPs), and cantilever resin-bonded fixed dental prostheses (RBFDPs), the mean utility values were 0.64 (SD = 0.27), 0.54 (SD = 0.20), 0.48 (SD = 0.20), 0.42 (SD = 0.28), and 0.39 (SD = 0.27), respectively. Neither patient age nor dentists' clinical experience had an impact on dentists' perceptions of the utility of unrestored SDAs and outcomes of this treatment concept (P > .01).
Restoration of SDAs by ISFDPs received the highest utility value among the surveyed group of dentists. Although the assigned value for unrestored SDAs was low, this value was comparable to the value of SDAs that were restored by acrylic RPDs or cantilever FDPs of either type.
本研究旨在评估牙医对于未修复的短牙弓(SDA)与各种修复治疗方案效用的看法。
对在沙特阿拉伯利雅得四个地点工作的142名牙医进行了访谈,并向他们展示了18种不同年龄、患有缺失磨牙的SDA患者的病例场景。要求参与者在标准化视觉模拟量表(VAS)上指出,如果SDA不进行修复或用五种口腔修复体进行修复,他们对患者口腔健康的评价。
效用值0.0代表口腔可能的最差健康状态,1.0代表最佳状态,牙医对未修复SDA的平均效用值为0.43(标准差[SD]=0.28)。对于种植支持的固定义齿(ISFDP)、钴铬可摘局部义齿(RPD)、丙烯酸树脂RPD、悬臂式传统固定义齿(CFDP)和悬臂式树脂粘结固定义齿(RBFDP),平均效用值分别为0.64(SD = 0.27)、0.54(SD = 0.20)、0.48(SD = 0.20)、0.42(SD = 0.28)和0.39(SD = 0.27)。患者年龄和牙医的临床经验均未对牙医对未修复SDA效用的认知以及该治疗理念的结果产生影响(P>.01)。
在接受调查的牙医群体中,ISFDP修复SDA获得了最高的效用值。尽管未修复SDA的赋值较低,但该值与丙烯酸树脂RPD或任何一种悬臂式固定义齿修复的SDA的值相当。
