Abstract

Background: The assessment of plaque indices may be time-consuming and error-prone. Simplification of these indices may increase their utility without compromising their validity. The aim of this study was to evaluate the validity of two simplified versions of the Marginal Plaque Index (MPI).

Methods: Two simplified versions of the MPI as well as the Plaque Control Record (PCR) were derived from full-scale MPI assessments in two studies with four age groups (N = 42 10-year-olds; N = 24 15 year-olds; N = 53 university students (18y-33y); N = 66 parents (32y-57y). Correlations with the Turesky modification of the Quigley-Hein Index (TQHI) and the Papillary Bleeding Index (PBI) were calculated.

Results: The indices derived from the MPI showed high convergence with each other (all r ≥ 0.94) and with the TQHI (r ≥ 0.80). The concurrent validity of the MPI with the PBI was equal to that of the TQHI in all age groups. The simplified versions of the MPI and the PCR show a lower convergent validity with the PBI than the MPI within parents (p < 0.05). In the other age groups, their convergent validity was equal to that of the MPI.

Discussion: Simplification of the MPI does not affect its convergent validity with other plaque indices but may reduce its concurrent validity with the PBI in middle-aged adults.

让斑块评估更简单--边缘斑块指数简化版的验证研究。

背景：评估斑块指数可能既费时又容易出错。简化这些指数可在不影响其有效性的前提下提高其实用性。本研究旨在评估两种简化版边缘斑块指数（MPI）的有效性：两个简化版的边缘斑块指数（MPI）和斑块控制记录（PCR）均来自两项研究中对四个年龄组（10 岁儿童 42 人；15 岁儿童 24 人；大学生（18 岁至 33 岁）53 人；父母（32 岁至 57 岁）66 人）的全面 MPI 评估。计算了与 Turesky 改良 Quigley-Hein 指数（TQHI）和乳头出血指数（PBI）的相关性：由 MPI 得出的指数彼此高度一致（r 均≥ 0.94），与 TQHI 也高度一致（r 均≥ 0.80）。在所有年龄组中，MPI 与 PBI 的并发效度与 TQHI 相当。简化版 MPI 和 PCR 与 PBI 的会聚效度低于 MPI 在父母内部的会聚效度（p 讨论）：在中年人中，简化 MPI 不会影响其与其他斑块指数的收敛有效性，但可能会降低其与 PBI 的并发有效性。
