Abstract:

The aim of periodontal therapy is to remove inflammation and prevent disease progression. Thorough debridement of subgingival root surfaces is considered as the gold standard of periodontal therapy. Conventional periodontal treatment technology includes blinded closed scaling/root planing（SRP）and open flap surgery. SRP is a standard treatment modality， but whether the treatment is complete relies on tactile perception. However the traditional tactile perception of the subgingival root surface is without visual accessibility and lacks sensitivity and specificity. Many aspects of clinical practice limit the clinician′s ability. The precise evaluation of subgingival accretions, root surfaces，and soft tissues under the endoscope is critical for diagnosing periodontitis，planning treatment，and estimating the benefits of therapy. In this paper，the structure and characteristics of the endoscope and its clinical application in the periodontology are discussed.

摘要：

牙周病治疗的总体目标是消除炎症和防止疾病进展。彻底的龈下清创术是牙周治疗的金标准。传统的牙周治疗技术包括盲法闭合龈下刮治、根面平整（SRP）和开放式翻瓣刮治手术。前者是标准的治疗方式，治疗是否完善要靠触觉感知，但龈下的触觉感知没有视觉可达性，且缺乏敏感性、特异性，会导致结石残留。而且很多因素限制了临床医生检测和去除牙结石的能力。内窥镜提供了明确的龈下空间，可精确地评估龈下的根表面和软组织情况，对于牙周炎的诊断、治疗和疗效评估至关重要。文章就内窥镜的构造、特点及其在牙周领域的临床应用进行讨论。
