Abstract

OBJECTIVES

To analyze the relief time and risk factors of biting/thermal sensitivity in cracked tooth (CT) restored using occlusal veneer.

METHODS

63 CT were analyzed, and their demographic and clinical data and medical history were collected. Patients were followed-up to examine the relief of thermal/biting sensitivity.

RESULTS

The maxillary first molar was the most prevalent (N = 25, 40%). The number of crack lines on the finish line ranged from 1 to 6 while the number of crack lines through preparation on the finish line from 0 to 4. Pain relief achieved steadily to 52% for thermal and 62% for biting at 1 week to over 90% for each by 3 months and was completely resolved (no pain) for each by 12 months. Painful of lateral percussion was related to a long period of thermal sensitivity (≥1 month) after restoration with occlusal veneer. The number of crack lines through preparation on the finish line >2 was correlated with biting sensitivity (≥1 month) post-treatment.

CONCLUSIONS

Most patients (>90%) became asymptomatic of biting and thermal sensitivity within 3 months of CT restored by occlusal veneer. Lateral percussion and the number of crack lines through preparation on the finish line could be significant factors affecting postoperative symptoms.

CLINICAL SIGNIFICANCE

Occlusal veneer is an ultrathin restoration and had no need for restricting clinical crown height, which could protect and relief the biting/thermal sensitivity of CT without preventive root canal therapy.

摘要

目的

分析牙隐裂（CT）经牙合面贴面修复后缓解咬/热敏感的时间和相关风险因素。

方法

分析了 63 例 CT，并收集了其人口统计学和临床数据以及病史。对患者进行随访，以检查热/咬敏感缓解情况。

结果

上颌第一磨牙最为常见（N=25，40%）。在边缘嵴，裂纹线数量从 1 条到 6 条不等，而在预备边缘，裂纹线数量从 0 条到 4 条不等。疼痛缓解情况稳定，1 周时热敏感缓解率为 52%，咬敏感缓解率为 62%，3 个月时每种敏感缓解率均超过 90%，12 个月时每种敏感均完全缓解（无疼痛）。修复后牙合面贴面出现侧向叩击痛与热敏感持续时间较长（≥1 个月）有关。预备边缘的裂纹线数量>2 与治疗后咬敏感（≥1 个月）有关。
