A comparative study of the postoperative effects of 0.2% hyaluronic acid and 0.2% chlorhexidine + 1% panthenol in tooth extractions performed at the Dr. René Puig Bentz Dental Clinic of the Pedro Henríquez Ureña National University.

The null hypothesis states that: There is no significant difference in efficacy between 0.2% AH
and 0.2% chlorhexidine + 1% panthenol gel in post-surgical treatment; while the alternative
hypothesis states that: 0.2% AH gel is more effective than 0.2% chlorhexidine + 1% panthenol
as an adjunct in the post-surgical process for simple extractions. Data collected from the
alveolar area were compared between AH patients and CH patients. Similarly, the other
variables collected were compared based on the type of compound. The analyses performed
demonstrated that there were no significant differences between the effectiveness of both
compounds, as well as their management of pain, bleeding, and other variables; supporting the
null hypothesis proposed. However, both achieved optimal post-surgical recovery. This means
that both compounds are equally effective in promoting healing, pain control, bleeding
management, and other outcomes in patients following simple extractions.

零假设（null hypothesis）指出：在术后治疗中，0.2% AH凝胶与0.2%氯己定+1%泛醇凝胶的疗效无显著差异；而备择假设（alternative hypothesis）则提出：在单纯拔牙术的术后辅助治疗过程中，0.2% AH凝胶的疗效优于0.2%氯己定+1%泛醇凝胶。研究人员对牙槽区域采集的数据在AH组与CH组患者间进行了对比，同时也依据受试化合物的类型对其余采集变量展开了比较。本次开展的分析结果显示，两种受试化合物的疗效以及其在疼痛控制、出血管理等指标上的表现均无显著差异，这验证了最初提出的零假设。不过，两种化合物均达成了理想的术后恢复效果。这意味着，在单纯拔牙术后患者的愈合促进、疼痛控制、出血管理及其他预后结局方面，两种化合物的疗效完全相当。
