The aim of this clinical study was to evaluate whether a correlation exists between three-dimensional tooth mobility (TM) and Periotest values for maxillary anterior periodontally involved teeth (pocket depth > 3 mm) before and after periodontal therapy.
Force-related TM was measured in 3 N intervals in 19 participants as they bit down on a load cell. Periotest values were evaluated at reproducible measurement points. Both measurement techniques were performed on maxillary central and lateral incisors and canine teeth before periodontal treatment and after a healing period of 3 months. The Pearson product-moment correlation coefficient was calculated to determine exploratory associations.
The comparison between TM and Periotest values indicated "high" and "optimum" correlations for maxillary central incisors before and after periodontal therapy. Lateral incisors exhibited "moderate" and "high" correlations, whereas canines exhibited "weak" and "moderate" correlations before and after periodontal therapy.
Periotest values may provide valuable information about quantitative metric tooth mobility in periodontally involved teeth. In future investigations, the study design can expand on various dental fields, such as implantology and traumatology.
本临床研究旨在评估在上颌前牙牙周受累牙齿(牙周袋深度>3mm)牙周治疗前后,三维牙齿松动度(TM)与牙周探针值之间是否存在相关性。
19名参与者咬在测力传感器上时,以3N的间隔测量与力相关的TM。在可重复的测量点评估牙周探针值。两种测量技术均在牙周治疗前以及3个月的愈合期后,对上颌中切牙、侧切牙和尖牙进行。计算Pearson积差相关系数以确定探索性关联。
TM与牙周探针值之间的比较表明,上颌中切牙在牙周治疗前后呈现“高度”和“最佳”相关性。侧切牙呈现“中度”和“高度”相关性,而尖牙在牙周治疗前后呈现“弱”和“中度”相关性。
牙周探针值可为牙周受累牙齿的定量度量牙齿松动度提供有价值的信息。在未来的研究中,研究设计可扩展到各个牙科领域,如种植学和创伤学。
