Effect of Injectable Hyaluronic Acid (HYADENT BG (HA)) on Bone Healing in Extraction Sockets

Complications such as postoperative pain and delayed socket healing are relatively common following surgical extraction of mandibular third molars. Various biomaterials have been investigated to enhance wound healing and reduce postoperative morbidity. Hyaluronic acid (HA) has demonstrated anti-inflammatory and regenerative properties that may improve both soft and hard tissue healing.

The aim of this study is to evaluate the effect of topical hyaluronic acid on postoperative pain and alveolar socket bone healing following surgical extraction of mandibular third molars. A prospective, randomized, controlled clinical trial with a split-mouth design will be conducted. Twenty patients requiring bilateral mandibular third molar surgical extraction will be enrolled. In each patient, one extraction socket will receive hyaluronic acid combined with a collagen sponge, while the contralateral socket will receive a collagen sponge alone, according to random allocation. Postoperative pain will be assessed using a visual analogue scale, and socket healing will be evaluated radiographically and histologically.
