Considering increasing rate of survival rate in these patients, disorders of oral cavity can lead to low quality of life and can affect the patient’s general health. The aim of this st...

Introduction: Dental abscesses and periodontal disease can be regarded as the common causes of odontogenic sinusitis. Apical periodontitis, periodontal disease, implant treatment and teeth extraction lead to the increase risk of maxillary sinus mucositis.
