The study was carried out from November 2018 to February 2019. The reasonfor extraction was documented whether by asking the patient why his/her tooth was extracted or by clinicaland radiographic examination for the tooth diagnosed for extraction. The criteria for extraction categories(reasons) were adapted based on Murray et al. 1996,3 and one reason for each tooth was recorded. The dataobtained were documented in a patient examination form then statistically analyzed.Results: A total of 1473 teeth were extracted or diagnosed for extraction from 404 patients. The prevalenceof patients who lost at least one tooth was (73.3%). The majority of patients lost 4-8 teeth (38.4%). Inaddition, the prevalence of patients who didn’t lose any teeth was the highest in the age group 10-29 years;however, the prevalence of patients who lost >8 teeth was the highest in the age group ≥51 years. Thehighest percentage of extracted teeth was in the lower posterior region (48.5%), and the lowest percentageof extracted teeth was in the lower anterior region. Furthermore, there was an insignificant difference in themean number of extracted teeth between males and females p>0.05. Moreover, caries was the most commonreason for tooth extractions in all ages (60.6%), followed by eruption problems (20.8%), periodontal disease(7.9%), orthodontics (6.4%), prosthodontics (1.8%), pericoronitis (1.6%), and trauma (0.9%). The meannumber of extracted teeth per patient by caries was (4.24±3.516). The mean number of extracted teeth perpatient was higher in the oldest age group ≥51 years than in the youngest age group 10-29 years. Thepercentages of extracted teeth due to caries and eruption problems were higher in patients ≤ 40 years thanin patients > 40 years, and they due to orthodontics and pericoronitis were the highest in patients 10-29years; however, they due to periodontal disease were higher in patients > 40 years than in patients ≤ 40years.Conclusion: Caries is epidemic; it’s advised to intensify efforts towards dental sealants and fluorideapplication with implementing dental preventive and educational programs in order to raise the publicawareness of oral hygiene instructions and natural dentition.","PeriodicalId":13970,"journal":{"name":"International journal of emerging trends in science and technology","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77859936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the construction was aborted due to lack of administrationmanagement and left the building under incomplete condition with only foundation and the first floorerected. Ten years afterward, the management decided to continue construct the building. This studyaimed to investigate the condition of existing building whether can be rebuilt properly corresponding tothe previous design. The investigation included structural cracks that happened on structural element aswell as the deflection of structural beams. The conditions of existing structural column have also beeninvestigated.The assessment process was conducted both on field and laboratory testing. The field testing was run withSchmidt Rebound Hammer test to know the compressive strength of structural concrete and its quality.The waterpass, theodolite, and tape measurement were used to measure the building geometric. SAP2000 computer package was used to analyze the structure. Loading test was carried out base on the totalmeasurement test which was required in SNI 03-2847-2002. The total measurement load of 700 kg/m2was employed representing U = 85% (1,4D + 1,7L), where D was dead load and L was live load. In thisstudy, the loading test was conducted on 300/700 and 200/500 size beams.Test result indicated that the qualities and the concrete compressive strengths on the buildingconstruction elements were varied. Steel reinforcement of structural columns was good enough towithstand the load, but, the column concrete strength should be improved. On the beam of 300/700 in thefirst floor, the deflection did not exceed the maximum deflection based on the code. However, themaximum deflection on 200/500 beam was 6.92 mm > 5.85 mm (maximum allowable deflection) andpermanent deflection after loading of 2.31 mm > 1.46 mm (maximum allowable permanent deflection).Therefore, rehabilitation and retrofitting of structural columns and 200/500 mm beam are essential.","PeriodicalId":13970,"journal":{"name":"International journal of emerging trends in science and technology","volume":"1 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79797164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
