Microleakage testing has been used to determine the possible clinical performance of a restorative material. Many microleakage testing materials have been developed and performed through the years. There has been no agreement as to which testing methodology would give the most accurate results. Attempts have been made to simulate the oral conditions and to give a more quantitative representation of micro leakage. The different micro leakage testing methodologies are presented in this paper.
This study is carried out to establish the prevalence of Work-related Musculoskeletal Disorders (MSD) among
the Malaysian workforce population in order to propose some measures to benefit the people at large. Secondary data
from three studies among drivers, clerical workers using visual display terminals (VDT) and fabrication workers were
used to report the prevalence of MSDs and the associated risk factors. The study identified high prevalence of MSDs in
multiple body regions. The MSD occurrence was also significantly associated with psychosocial factors. There is need
for organisations to consider such factors in work design, which will reduce the high prevalence and high financial
implications associated with MSDs among workers.
