J Periodontol:上颌前牙牙龈退缩与颊侧牙槽骨厚度的关系

2020-04-30 网络 网络

牙龈退缩和颊侧骨板薄或缺如经常发生在上颌前牙,需要制定详细的治疗计划预防并发症。然而,目前尚不清楚这两种情况之间的关联性,而且牙龈退缩是否能够预测潜在的骨缺损也是未知的。

牙龈退缩和颊侧骨板薄或缺如经常发生在上颌前牙,需要制定详细的治疗计划预防并发症。然而,目前尚不清楚这两种情况之间的关联性,而且牙龈退缩是否能够预测潜在的骨缺损也是未知的。因此,本研究旨在利用临床和影像学数据来检测这种关联,并确定人口参数和临床参数的影响。

本研究包括一项单中心的回顾性研究。实验纳入66名成年受试者,进行牙周检查和锥体束计算机断层扫描(CBCT)。使用CBCT测量沿牙根表面两点的颊侧牙槽骨宽度和牙槽嵴与釉牙骨质界(CEJ)之间的距离,并对结果进行了分析,确定牙龈退缩的存在与颊侧牙槽骨放射学表现的关联,以及人口统计学参数和其他临床结果对牙龈退缩和颊侧牙槽骨情况的影响。

结果发现,32.9%的上颌前牙有牙龈退缩,在尖牙处最常见,其次是侧切牙和中切牙。颊侧牙槽骨平均宽度明显低,CEJ和牙槽嵴之间的距离明显大于有牙龈退缩的牙齿。因此,在CEJ根尖4mm处的颊侧牙槽骨厚度<1 mm时,牙龈退缩可作为预测因素(概率比2.733,95%置信区间1.644~4.543,P<0.0001)。探诊深度与是否有牙龈退缩有关,而患者性别、年龄和牙龈冠根向高度与颊侧骨厚度相关。

因此,在本研究的范围内,上颌前牙有牙龈退缩的患者更容易出现薄(<1 mm)的牙槽骨。

J Periodontal Res:苯妥英钠改善牙龈成纤维细胞老化与自噬相关

人牙龈成纤维细胞老化是牙周疾病的一个重要原因。苯妥英钠(phenytoin)对牙龈存在副作用导致牙龈增生,对自噬进程也有一定的影响。这篇研究的目的是为了评估phenytoin对牙龈成纤维细胞老化的影响

J Periodontal Res:人老化牙龈成纤维细胞的炎症、增殖和细胞骨架反应改变

组织结构和功能降低是老化的特征,它可以理解为是由于细胞老化而产生。然而,对于获取老化牙龈成纤维细胞的表型反应的研究还较少。为此,这篇研究的目的是为了评估原代培养的人牙龈成纤维细胞增殖是否会影响与细胞老化以及组织衰退相关的细胞功能。

下颌牙龈原发性皮脂腺癌1例

口腔原发性皮脂腺癌(sebaceous carcinoma,SC)是一种极其少见的恶性肿瘤,检索国内外文献报道仅10余例,其主要发生于颊黏膜,其次为口底、唇黏膜、舌和上颌牙龈,仅见1例报道发生于下颌牙龈黏膜。本文现报道1例发生于下颌牙龈黏膜的原发性SC,回顾性分析其临床病理特征,并复习相关文献,旨在提高对该疾病的认识,有利于正确诊断。
