Large periapical defects may adversely affect the success rate of endodontic surgery. Use of regenerative therapy may enhance the prognosis of such teeth. A case of traumatized upper anterior teeth with infected radicular cyst and associated sinus tract reported to the dental hospital. A periradicular surgical procedure was performed to remove the nonhealing pathological tissue. To augment the ...

IRM has been recommended for root end filling during endodontic surgery. This study evaluated the seal of IRM root end fillings prepared with various powder to liquid ratios (P:L) at extended time intervals using a fluid filtration method. The P:L of IRM evaluated included 2, 3, 4, 5, and 6 g/ml and the P:L which resulted from the manufacturer's recommended scoop and dropper. Ten teeth were eva...

This case report describes the endodontic treatment of a large cyst-like periradicular lesion a 29-year-old female with a large chronic periapical abscess in the region of right maxillary sinus presented into private practice, accompanied with non-vital first upper molar and poorly root treated second upper molar. Conservative root canal treatment was carried out for both of the involved teeth ...

Cholesterol granuloma (CG) is a tissue reaction in response to the accumulation of cholesterol crystals rarely found in the maxillary sinus. The etiopathogenesis of maxillary sinus CG remains unclear. We reviewed the literature and added two new reports of cholesterol granuloma in maxillary sinus related to endodontically treated maxillary posterior teeth. The first report refers to a 45-year-o...

The patient, an 18-year-old man, presented pain in the region of the mandibular body on the right side. On clinical exam, bone expansion was observed in the region at the bottom of the vestibular sulcus, pain on palpation, slight extrusion of tooth 46 with presence of pulp vita...

Currently, although ultrasonics (US) is used in dentistry for therapeutic and diagnostic applications as well as for cleaning of instruments before sterilization, its main use is for scaling and root planing of teeth and in root canal therapy, both for orthograde and retrograde therapy. Both in conventional and surgical treatments, US in endodontics has enhanced quality of clinical procedures a...

In recent years, periapical surgery has evolved thanks to new diagnostic and technical advances. A review is made of the literature on periapical surgery of the antral teeth, based on a Medline search and on the revision of Spanish dental journals in the period between 1974 and 2003. The anatomy of the maxillary sinus is discussed, along with the diagnosis of periapical lesions and the relation...

The immediate placement of implants in the fresh extraction sockets of infected teeth with periradicular and periapical lesions is contraindicated because of both the infection and the loss of architecture required for proper implant placement. There are 4 approaches for implant replacement of a hopeless tooth with lesions: (1) extraction and delayed implant placement; (2) extraction, debrideme...

The surgical treatment of a case of anesthesia that occurred with the extrusion of Endomethasone root canal sealer into the mandibular canal is presented. Endomethasone is a neurotoxic root canal sealer containing paraformaldehyde and eugenol. The literature indicates immediate surgical decompression on the extrusion of Endomethasone into the mandibular canal. In our case, the decompression sur...
