Abstract

Objectives: The present study investigated the prevalence of mechanical allodynia (MA) in healthy teeth adjacent and contralateral to endodontically diseased teeth.

Materials and methods: This cross-sectional study included 114 patients with symptomatic irreversible pulpitis and apical periodontitis in permanent mandibular first molars who possessed healthy teeth adjacent and contralateral to the endodontically diseased tooth. The mechanical sensitivity of the teeth was determined by percussion testing. The presence or absence of pain on percussion in the teeth adjacent and contralateral to the endodontically diseased tooth and the tooth distal to the contralateral symmetrical tooth was recorded according to coding criteria. The prevalence of MA was computed as a percentage, and binary logistic regression analysis was done. The Fisher exact test and Mann-Whitney U test were used for binary and ordinal data.

Results: Age and sex did not influence the prevalence of MA. An increased prevalence of MA was found in patients with higher levels of spontaneous pain (p < 0.001). The prevalence of allodynia was 57% in teeth adjacent to endodontically diseased teeth and 10.5% in teeth contralateral to endodontically diseased teeth. In addition, on the ipsilateral side, there were more painful sensations distal to the diseased tooth than mesially.

Conclusions: Despite being disease-free, teeth adjacent and contralateral to endodontically diseased teeth exhibited pain on percussion. There was a direct association between the severity of the patient's pain and the presence of MA.

牙髓病牙齿邻近和对侧健康牙齿的机械异感评估:一项临床研究。
研究目的本研究调查了牙髓病牙齿邻侧和对侧健康牙齿机械过敏症(MA)的患病率:这项横断面研究纳入了 114 名患有无症状不可逆牙髓炎和下颌第一恒磨牙根尖牙周炎的患者,这些患者拥有与牙髓病牙相邻和对侧健康的牙齿。通过叩诊测试确定牙齿的机械敏感性。根据编码标准,记录牙髓病牙的邻牙和对侧牙以及对侧对称牙远端在叩击时有无疼痛。以百分比计算 MA 患病率,并进行二元逻辑回归分析。对二元和序数数据采用费舍尔精确检验和曼-惠特尼U检验:结果:年龄和性别对 MA 患病率没有影响。自发性疼痛程度较高的患者 MA 患病率增加(p < 0.001)。异感症的患病率在牙髓病牙邻近的牙齿中为 57%,在牙髓病牙对侧的牙齿中为 10.5%。此外,在同侧,病牙远端比中线有更多的痛感:结论:尽管没有病变,牙髓病变牙齿的邻牙和对侧牙在叩击时仍有疼痛感。患者疼痛的严重程度与 MA 的存在有直接关系。
