The aim of this study was to evaluate the risk factors associated with noncarious cervical lesions (NCCLs), cervical dentin hypersensitivity (CDH), and gingival recession (GR), besides the relationship among these conditions in a specific Brazilian sample population.
185 patients who attended the "Ambulatory Program for Rehabilitation of Patients with Noncarious Cervical Lesions and Cervical Dentin Hypersensitivity" were evaluated, and 5180 teeth were analyzed. The subjects filled out a form and a calibrated examiner performed the clinical exams to determine the presence of NCCLs, CDH, and GR. NCCLs were classified according to their morphology and depth, CDH levels were evaluated according to air stimuli response, and GRs were categorized according to Miller's classification. The association of the risk factors with NCCLs, CDH, and GR was determined with the Mann-Whitney U test and multiple linear regression. For the correlations, the Spearman test was used with a 95%-confidence level.
The NCCLs, CDH, and GR distributions within the study were 88.1%, 89.1%, and 59.4%, respectively. Maxillary premolars were the most affected by all three conditions. A positive correlation was found between age, NCCLs, and GR; between NCCLs and CDH; CDH and GR; GR and NCCLs. Age, gender, oral hygiene, gastroesophageal diseases, and occlusal trauma were significantly associated with the presence of all three conditions.
The NCCLs and GR distributions increased with age; NCCLs, CDH, and GR had positive correlation; the lesions' depth and morphology contributed to high levels of sensitivity and severity of recessions; age, gender, gastric disease, and occlusal trauma were relevant factors for the occurrence of NCCLs, CDH, and GR.
The increasing distribution of NCCLs, CDH, and GR is closely associated with people's lifestyles. Thus, it is important for the clinicians to recognize the etiological factors and their most relevant associations to prevent and control such alterations, in order to improve the population's quality of life.
本研究旨在评估与非龋性颈（NC）、牙本质过敏症（CDH）和牙龈退缩（GR）相关的风险因素，并评估这些情况在特定巴西样本人群中的关系。
评估了参加“非龋性颈病变和牙本质过敏症患者康复门诊计划”的 185 名患者，共分析了 5180 颗牙齿。患者填写一份表格，由经过校准的检查者进行临床检查，以确定 NC、CDH 和 GR 的存在。NC 根据其形态和深度进行分类，CDH 根据空气刺激反应进行评估，GR 根据 Miller 分类进行分类。使用 Mann-Whitney U 检验和多元线性回归确定风险因素与 NC、CDH 和 GR 的关联。为了进行相关性分析，使用 Spearman 检验，置信水平为 95%。
研究中 NC、CDH 和 GR 的分布分别为 88.1%、89.1%和 59.4%。上颌前磨牙是所有三种情况中最易受影响的牙齿。年龄、NC 和 GR 之间存在正相关；NC 和 CDH 之间、CDH 和 GR 之间、GR 和 NC 之间也存在正相关。年龄、性别、口腔卫生、胃食管疾病和咬合创伤与所有三种情况的发生有显著相关性。
NC 和 GR 的分布随年龄增长而增加；NC、CDH 和 GR 之间存在正相关；病变的深度和形态导致了较高水平的敏感性和退缩的严重程度；年龄、性别、胃疾病和咬合创伤是 NC、CDH 和 GR 发生的相关因素。
NC、CDH 和 GR 的分布增加与人们的生活方式密切相关。因此，临床医生认识到病因因素及其最相关的关联对于预防和控制这些变化以提高人群的生活质量非常重要。
