Evaluation of dental treatment as a risk factor for maxillary sinusitis a cohort study

Abstract

Maxillary sinus has been present in close proximity to maxillary posterior newlineteeth and has been known to cause infections secondary to odontogenic newlinepathology. Prevalence of odontogenic sinusitis accounts for 10-12% caused newlinemainly due to periapical infection or iatrogenic causes such as implant newlinesurgery complications and maxillofacial surgery. These would lead to violation newlineof the Schneiderian membrane leading to maxillary sinusitis which is the newlineprimordial manifestation of odontogenic sinusitis. newlineAim: newlineTo evaluate whether the dental treatment of maxillary posterior teeth is a risk newlinefactor for the occurrence of maxillary sinusitis. newlineMaterials and Methods: newlineThis study was conducted in a Saveetha Dental College and Hospital, the newlinestudy groups consist of an exposure group which includes treatment done in newlinemaxillary posterior teeth and non-exposure where treatment is done in the newlinemandibular teeth. The design is a cohort study where a total of 483 cohorts newlinewere included from the dental outpatient department which includes 232 newlineexposure and 251 non-exposure. Patients demographic data, dental status, newlinedental treatment status such as extraction, root canal therapy and Implant newlineplacement of upper second premolar and first molar, Clinical grading of newlineseverity of maxillary sinusitis using SNOT-22 questionnaire and Radiological newlinegrading using Lund-Mackay system were documented. The data extraction newlinewas subjected to statistical analysis using descriptive statistics to evaluate newlinethe frequency distribution of maxillary sinusitis in both treatment and no newlinetreatment groups and the association was evaluated using relative risk and newlineattributable risk analysis. newlineResults: newlineDistribution of maxillary sinusitis among the exposure group was 34.97% newlineand in the non-exposure group was 65.03%. Grading of the severity of newlinemaxillary sinusitis following dental treatment using SNOT-22 questionnaire in newlineboth exposure and non-exposure groups revealed severe grading of newlinesinusitis seen highest in the exposure group (75%) and very mild grading of newlinesinusitis seen
