Prevalence and complication of erupted-ing wisdom tooth among patients attending Shenen gibe hospital ,jimma ethiopia

Abstract

BACKGROUND:-The tooth to be said erupted when all cusps were visible and rich functional occlusion. There is average eruption period for each tooth in both quadrants. Wisdom teeth technically referred to as third molar are usually the last teeth to erupt and are located in the back part of your mouth. It presents between ages of 17 and 25 years although there is wide variation in the age of presentation. Even if the eruption of wisdom tooth is not that much important for chewing purpose we should have to know the relation between each antagonist tooth since any abnormality may lead to pain, swelling, pericoronitis, periodontal disease and caries. Impacted wisdom tooth are third molars that are not ordinarily to erupt into functional teeth. It is believed that the incidence of eruption of wisdom tooth is decreasing in recent years due to the less functional activity of the jaws . OBJECTIVES:-To assess the prevalence and complication of erupting wisdom teeth among patients attending SHENEN GIBE hospital, JIMMA, Ethiopia. METHODOLOGY:- A hospital based cross-sectional type of study using simple random sampling technique was conducted in SHENEN GIBE hospital from, April 5 to 20 2013. G.C with the aim of assessing the prevalence and complication of erupting wisdom tooth on 320 adult patient attending SHENEN GIB hospital. The individuals were selected by giving number (1-32) and with 28 zero so those pick zero ignored and the data was collected using structured questioner and clinical examination. Oral examination was performed using mirror and graduated probe then analyzed using online contingency table and manually, finally the result was presented by table, statement and figures. RESULT:- In study population female accounts 56.25%, the largest group of the target population is in the age of 25-45 which accounts 47.21%. Muslim is the largest religion [80%] and Oromo is the largest ethnicity [61.25%]. 82%, of study population is urban resident. Overall prevalence of erupted-ing wisdom tooth is 45.03%, for mandibular tooth and 76%, for maxillary tooth in either side of the jaw. The prevalence of symptomatic periodontal disease is 22.05% while asymptomatic 60.63%. Pericoronities to partially impacted wisdom tooth accounts 39% . The study further revealed that 89, parents of the population experience complain around wisdom tooth 65.17%, have pain and 34.83%, have both swelling and pain. Conclusion and recommendation:- There is an association of periodontal disease and erupted-ing wisdom tooth .The study also reviles absence of symptoms doesn't show absence of disease. I recommend dental practitioner to examine strictly periodontium of each wisdom tooth for each client. Dental professionals and councils should carry out further research on this topic to identify other factors associated with wisdom tooth status and come up with better result.
