Plaque quantification indices are frequently used to evaluate personal oral hygiene. Education in self-care and self-diagnosis is effective in prevention and control of both dental and periodontal disease. Mobile technology has become a ubiquitous technology and can be particularly useful in the self-monitoring of health promotion. To evaluate the selfie dental plaque index compared with O´Leary index (DPI) and visible plaque index (VPI). The secondary outcome was to compare full-mouth and anterior teeth plaque index analysis.
A sample of 47 adults were evaluated using a four-stage protocol. All teeth (except third molars) were analyzed for VPI and DPI. A selfie Digital Camera captured the image of the patient's smile (without and with disclosing solution), which was analyzed using Image J software (ImageJ 1.52a, National Institutes of Health). Adobe Photoshop software (Copyright © 2020 Adobe) was used for individual segmentation. The calculation of the selfie index of visible plaque (SVPI) and disclosed (SDPI) was done through the area with plaque of each image in relation to the total teeth area.
Spearman's correlation test showed a moderate correlation between VPI and SVPI (rho = 0.6, <0.001), whereas between DPI and SDPI the correlation was weak (rho = 0.2, p = 0.13). The correlation between the plaque index using all the teeth present, showed a strong correlation with the analysis only of the anterior teeth (rho = 0.8, <0.001).
Our results showed the potential of smiling images as a new tool for quantitative measurements and showed moderate correlation when compared with the visible plaque index. Anterior teeth provided reliable plaque indexes when compared with full mouth analysis. Dental Plaque Index, dental hygiene, mHealth, health Promotion, oral Health.
菌斑量化指标常用于评估个人口腔卫生状况。自我护理和自我诊断教育对预防和控制牙齿及牙周疾病有效。移动技术已无处不在，在健康促进的自我监测中可能特别有用。旨在评估自拍牙菌斑指数与奥利里指数（DPI）和可见菌斑指数（VPI）相比的情况。次要结果是比较全口和前牙菌斑指数分析。
采用四阶段方案对47名成年人样本进行评估。分析所有牙齿（第三磨牙除外）的VPI和DPI。用自拍数码相机拍摄患者微笑的图像（有无菌斑显示剂），使用Image J软件（ImageJ 1.52a，美国国立卫生研究院）进行分析。使用Adobe Photoshop软件（版权所有©2020 Adobe）进行个体分割。通过每张图像中菌斑面积与牙齿总面积的关系计算可见菌斑自拍指数（SVPI）和显示菌斑自拍指数（SDPI）。
Spearman相关性检验显示VPI与SVPI之间存在中度相关性（rho = 0.6，<0.001），而DPI与SDPI之间的相关性较弱（rho = 0.2，p = 0.13）。使用所有现存牙齿的菌斑指数与仅分析前牙的菌斑指数之间存在强相关性（rho = 0.8，<0.001）。
我们的结果表明微笑图像作为定量测量新工具的潜力，与可见菌斑指数相比显示出中度相关性。与全口分析相比，前牙提供了可靠的菌斑指数。牙菌斑指数、口腔卫生、移动健康、健康促进、口腔健康。
