Gingival Recession and Sensitivity: Observation, a Restoration or Root Coverage?｜證據鏈

Root exposure after gingival recession may bring sensitivity to cold, discomfort during brushing, cervical tooth wear and aesthetic concerns at the same time, but these problems are not necessarily resolved by the same treatment. Observation and non-surgical treatment focus on stopping continuing irritation, improving cleaning methods and controlling sensitivity. A restoration treats the cervical defect and surface contour. Root-coverage surgery moves or adds soft tissue. Before choosing, the recession type, interdental attachment, whether a non-carious cervical lesion is already present, soft-tissue thickness and the symptom you most want to improve should first be established. For sensitivity associated with gingival recession, a systematic review and meta-analysis included 13 randomised trials, 701 patients and 1,086 recession sites. After root-coverage surgery, the proportion with suppression of sensitivity was 70.8%, with a 95% confidence interval of 64.4%–76.6%. This is an average across techniques and studies; it does not mean that every site will achieve the same improvement, and it did not directly compare surgery with simple observation or every non-surgical treatment for sensitivity.
