HUBUNGAN ANTARA MASA KERJA DENGAN KEJADIAN GINGIVAL LEAD LINE PADA PEKERJA BENGKEL MOTOR DI SEMARANG

Abstract

Background: Early detection of lead poisoning can be seen from the gingival lead line, in the form of grayish blue to black line at the edge of the gums. Work duration were reported to have an influence on the incidence of gingival lead line. This study aimed to investigate the correlation between work duration with the incidence of mechanics’ gingival lead line on mechanics of motor repair shops in Semarang. Methods: This research was an observational study with cross-sectional design, consisted of 30 mechanics who fulfilled all criterias. This research carried out during March until July 2010. Data were obtained through questionnaire and analyzed using Spearman test with SPSS for Windows 11.5. Result: The result of the study showed that 3 respondents with short work duration had moderate and high-grade of gingival lead line. 4 of 6 respondents with moderate work duration had moderate and high-grade of gingival lead line, the other 2 respondents were normal. Most of the long work duration respondents had high-grade of gingival lead line with 47.62% from 21 respondents. Conclusion: There was an incidence of gingival lead line of mechanics with long duration of work, but the correlation was not significant. Keywords: Work duration, gingival lead line, mechanics
