This study investigated the effectiveness of scaling/root planing using closed approach, closed approach with laser-curettage, closed approach with laser-curettage/laser-sealing, and an open approach (papilla reflection/flap closure) in treating moderate-advanced chronic periodontitis. All treatments resulted in a reduction in probing depth and bleeding upon probing. The closed approach therapies: SRP, laser-curettage/SRP, and laser-curettage/SRP/laser-sealing resulted in less gingival recession than the open approach (papilla reflection/flap closure). If esthetics are a concern, laser-curettage is a viable option.
本研究调查了采用闭合入路洁治/根面平整、闭合入路联合激光刮治、闭合入路联合激光刮治/激光封闭以及开放入路（乳头翻开/瓣关闭）治疗中重度慢性牙周炎的有效性。所有治疗均导致探诊深度降低和探诊出血减少。闭合入路治疗方法：单纯根面平整、激光刮治/根面平整以及激光刮治/根面平整/激光封闭导致的牙龈退缩少于开放入路（乳头翻开/瓣关闭）。如果美观是一个关注点，激光刮治是一个可行的选择。
