Investigations of toothbrushing habits are an important vector to understand their influence on brushing effectiveness. User compliance in toothbrushing is known to deviate from professional recommendations in brushing time, evenness across all areas of the dentition, and brushing force [1,2]. Despite the recent development of tools designed to guide users to optimised brushing habits [3,4], research on habit evaluation and tracking is limited and typically relies on labour-intensive video observation (VO) [5]. Here we present raw data on toothbrush position as determined by an automated motion tracking (MT) capability and by human VO and provide a technical description of the MT capability. The MT system described in this article was developed in collaboration with Soft2Tec GmbH (Rüsselsheim, Germany) as a potential substitute for the VO tool. The MT system consists of a monocular vision module and a target module with active infrared LED trackers. The MT system determined the position and orientation of a toothbrush relative to the jaw while subjects brushed under realistic conditions. For VO, a trained assessor coded video recording data from toothbrushing sessions. The data presented here describes a clinical study (103 subjects; 46 completed two sessions, 57 completed one session, altogether 149 events) comparing toothbrushing behaviour recorded with the MT system and with VO simultaneously. The raw data was deposited in Mendeley Data, under data identification number doi:10.17632/4f384xrbhm.1 [https://data.mendeley.com/datasets/4f384xrbhm/1].
对刷牙习惯的调查是了解其对刷牙效果影响的重要途径。众所周知，用户在刷牙时间、牙列所有区域的均匀度以及刷牙力度方面的依从性与专业建议存在偏差[1,2]。尽管最近开发了旨在引导用户养成优化刷牙习惯的工具[3,4]，但关于习惯评估和跟踪的研究有限，通常依赖于劳动强度大的视频观察（VO）[5]。在此，我们展示了通过自动运动跟踪（MT）功能和人工VO确定的牙刷位置的原始数据，并提供了MT功能的技术描述。本文所述的MT系统是与Soft2Tec GmbH（德国吕塞尔斯海姆）合作开发的，作为VO工具的潜在替代品。MT系统由一个单目视觉模块和一个带有有源红外LED跟踪器的目标模块组成。MT系统在受试者在实际条件下刷牙时确定牙刷相对于颌骨的位置和方向。对于VO，一名经过培训的评估人员对刷牙过程的视频记录数据进行编码。此处呈现的数据描述了一项临床研究（103名受试者；46名完成了两个阶段，57名完成了一个阶段，共149个事件），同时比较了用MT系统和VO记录的刷牙行为。原始数据已存入Mendeley Data，数据识别号为doi:10.17632/4f384xrbhm.1 [https://data.mendeley.com/datasets/4f384xrbhm/1]。
