Short-term treatment of periapical lesion of anterior tooth affected by microleakage using Nd:YAG laser. Case report

Tooth-colored restorations are the first choice for anterior restorations. However, microleakage is a significant problem at the margins of anterior cavities restored with resin composites. Microleakage can cause pulpal irritation and periapical inflammation. Today, laser irradiation is used frequently for dental treatments. Nd:YAG laser has been used successfully in endodontic treatments. A 17-year-old male presented to our clinic with a maxillary right lateral incisor that resulted in microleakage of an old composite resin restoration. Clinical examination revealed swelling and abcess formation on the palatal mucosa. The radiographic examination was performed and an inflammation around the apex was diagnosed. Root canal preparation, canal sterilization by Nd:YAG laser and root canal filling were performed at the same visit. The patient was observed for two months. In the case presented here, short-term treatment of a periapical lesion of an anterior tooth affected by microleakage using the Nd:YAG laser is discussed.
