Palatal groove represents a relatively uncommon developmental root anomaly, usually found on the palatal aspect of maxillary incisors. While its origin is controversial, its presence predisposes to severe periodontal defects.
This study aimed to provide a systematic review of the literature focusing on the varied diagnostic techniques and treatment modalities for periodontal lesions arising from the presence of palatal groove. Based on the existing evidence and knowledge, the study also provides a comprehensive decisional tree, guiding clinicians in the challenging decision-making process face to a palatal groove.
The literature search was conducted on Medline and Cochrane databases by two independent reviewers, who also performed the screening and selection process, looking for English written articles reporting on diagnosis and management (all treatment approaches) of periodontal lesion(s) associated with a palatal groove. Based on this literature, a comprehensive decisional tree, including a standardized palatal groove evaluation and tailored treatment approaches, is proposed. Moreover, a clinical case is described to demonstrate the practical application of the developed decisional tree.
Over a total of 451 articles initially identified, 34 were selected, describing 40 patients with 40 periodontal lesions associated with palatal grooves. The case report illustrates a deep, large, circumferential intra-bony defect on the palatal side of the tooth #22 associated with a shallow, moderately long palatal groove in an 18-year-old male patient. Following reevaluation, a single flap surgery was deemed necessary, combined with a regenerative procedure. At 2 years post-treatment, the tooth #22 is healthy, in a functional and esthetic position. The decision-making process, based on local and systemic patient's conditions, should allow an early and precise diagnosis to prevent further complications and undertake an adequate treatment.
Palatal grooves are relatively rare; however, they are frequently associated with severe periodontal defects. The identification, diagnosis, prompt, and tailored management of the associated lesion is essential to mitigate potential periodontal and endodontic complications related to the presence of palatal groove.

腭沟是一种相对罕见的发育性牙根异常，通常发生在上颌切牙的腭侧。虽然其起源存在争议，但它的存在易导致严重的牙周缺损。
本研究旨在对文献进行系统回顾，重点关注源于腭沟存在的牙周病变的各种诊断技术和治疗方式。基于现有证据和知识，该研究还提供了一个全面的决策树，指导临床医生在面对腭沟时进行具有挑战性的决策。
两名独立的审查员在 Medline 和 Cochrane 数据库中进行了文献检索，他们还进行了筛选和选择过程，寻找报告与腭沟相关的牙周病变（所有治疗方法）的诊断和管理的英文文章。基于这些文献，提出了一个全面的决策树，包括标准化的腭沟评估和定制的治疗方法。此外，还描述了一个临床病例，以展示所开发决策树的实际应用。
在最初确定的 451 篇文章中，共选择了 34 篇文章，描述了 40 例患者的 40 个与腭沟相关的牙周病变。病例报告说明了一个 18 岁男性患者的 22 号牙腭侧存在一个深而大的、环形的骨内缺损，伴有一个浅而长的腭沟。经过重新评估，认为需要进行单瓣手术，并结合再生程序。治疗后 2 年，22 号牙健康，处于功能和美观的位置。基于患者的局部和全身状况的决策过程，应允许进行早期和精确的诊断，以防止进一步的并发症，并采取适当的治疗。
腭沟相对罕见，但它们常与严重的牙周缺损有关。对相关病变的识别、诊断、及时和定制管理至关重要，可以减轻与腭沟存在相关的潜在牙周和牙髓并发症。
