研究目的:

评估一种生物生物组装高分子脱敏剂在非手术牙周治疗后对牙本质敏感的短期及中期缓解效果,探究其在敏感性参数(VAS 评分及主观感受)和临床参数(探诊深度、临床附着丧失、探诊出血)的改善效果,并为非手术牙周治疗后的抗敏感治疗方案提供依据。  

Objectives of Study:

To assess the short-term and mid-term efficacy of a biologically assembled polymer desensitizer in alleviating dentin hypersensitivity following non-surgical periodontal treatment, to evaluate its improvements in sensitivity parameters (VAS score and subjective perception) and clinical parameters (probing depth, clinical attachment loss, and bleeding on probing), and to provide a basis for anti-sensitivity treatment strategies after non-surgical periodontal therapy.

Description for medicine or protocol of treatment in detail:

1. Aged 18-70 years, regardless of gender; 2. Diagnosed with periodontitis (according to the 2018 new classification of periodontal diseases) and scheduled to undergo full-mouth non-surgical periodontal treatment (NSPT); 3. Presence of at least two affected teeth in different quadrants (or contralateral homonymous teeth) confirmed to have dentin hypersensitivity symptoms [VAS score >= 4 (out of a total score of 10)]; 4. The affected teeth are caries-free, crack-free, and have intact dental restorations; 5. No professional anti-sensitive treatment or periodontal surgery received in the past 3 months; 6. Agree to participate in this study, sign the informed consent form, and demonstrate good compliance.

排除标准:

1. 患牙存在急性牙周脓肿、牙髓炎或根尖周病变; 2. 患有严重或未控制的系统性疾病(如严重高血压、糖尿病、肝肾功能不全); 3. 长期服用抗凝药物、镇痛类药物、抗炎药或抗抑郁药(可能干扰痛觉感知); 4. 存在未控制的酸蚀症(如胃食管反流病)或饮食障碍(如神经性厌食症); 5. 已知对研究材料成分过敏者; 6. 妊娠期或哺乳期女性; 7. 正在进行正畸治疗者。

Exclusion criteria:

1. The affected tooth presents with acute periodontal abscess, pulpitis, or periapical lesions; 2. Presence of severe or uncontrolled systemic diseases (e.g., severe hypertension, diabetes, hepatic or renal insufficiency); 3. Long-term use of anticoagulants, analgesics, anti-inflammatory drugs, or antidepressants (which may interfere with pain perception); 4. Uncontrolled dental erosion (e.g., due to gastroesophageal reflux disease) or eating disorders (e.g., anorexia nervosa); 5. Known allergy to any component of the study material; 6. Pregnant or breastfeeding women; 7. Currently undergoing orthodontic treatment.

Calculated Results after the Study Completed public access:

公开/Public

盲法:

本研究实施双盲。 受试者盲: 试验药物与安慰剂外观、包装一致,且自带非抗敏感牙膏,受试者不知晓具体分组。 检查者盲: 进行敏感度评分(VAS)和牙周检查的医生不参与药物涂布,也不知晓分组情况。

Blinding:

This study implemented a double-blind design. Subject blinding: The trial drug and placebo are identical in appearance and packaging, and are provided with a non-desensitizing toothpaste. The subjects are unaware of the specific group allocation. Examiner blinding: The doctors conducting the sensitivity score (VAS) assessments and periodontal examinations are not involved in the application of the drug and are unaware of the group allocation.
