Oral surgeries involving the extraction of cheek teeth have a very high complication rate. Complications have been reported at 32% and as high as 70%. Recognition before occurrence helps the veterinarian to reduce the incidence and be prepared for a complication(s). Common indications for extraction include dental fracture, end-stage periodontal disease, severe decay/cavity, and periapical absc...

We report a case of chronic maxillary sinusitis caused by denture lining material entering through an oroantral fistula after tooth extraction. The patient was an 80-year-old female who visited us with a complaint of pus discharge from the right posterior maxilla. She had extraction of the upper right second molar and had her upper denture relined with silicone lining material. The patient noti...

The authors present the problems of oroantral fistula by reviewing the possibilities of surgical treatment. Known and less known operative methods are described and their advantages and disadvantages analysed. The object of this study is to remind the reader of the iatrogenic possibility of the occurrence of an antrooral communication and possibility of the development of a fistula and infectio...

Odontogenic sinusitis accounts for 10-12% of maxillary sinusitis. It occurs due to an interruption of the mucoperiosteum in response to a series of conditions, most frequently the extraction of a superior tooth. Its treatment has two bases: treating the infection and managing the oroantral fistula that perpetuates the infection. Communications smaller than 5mm can resolve spontaneously; bigger ...

Oroantral communication (OAC) is a pathological pathway between the oral cavity and the maxillary sinus. Extraction of maxillary posterior teeth is the most common cause of OAC. Maxillary cysts, benign or malignant tumors and trauma can be other causes of OAC [1]. OACs must be sealed in order to prevent the escape of fluids, other mouth contents, and oral bacteria into the maxillary sinus. So t...

Communication between the maxillary sinus and oral cavity is a common complica‐ tion in oral surgery. It results mainly from maxillary premolar and molar extractions when the sinus floor is close to the tooth apex. It can also occur after an infection involving the maxillary teeth, invasion of the sinus cavity by a cyst or carcinoma, trauma, the Caldwell-Luc operation, or other dentoalveolar or...

Introduction: the Oroantral Communication (OAC) is space that created between maxillary sinus and oral cavity, which if not treated will progress to an Fistula (OAF) or chronic disease. The most common predisposing factor for a COA extraction of upper posterior teeth (usually first second molars). aim this study was carry out literature review with emphasis on clinical implications treatment al...
