Prevalence of Musculoskeletal Symptoms among Dental Health Workers, Southern Thailand.

Objectives. The objective of this study was to describe the socioeconomic situation of dental health work and work characteristics and to evaluate the prevalence of musculoskeletal symptoms among dental health workers. Material and Methods.

An in situ FTIR spectroscopic and thermogravimetric analysis study of the dehydration and dihydroxylation of SnO2: the contribution of the (100), (110) and (111) facets.

Nanoparticulate SnO2 produced by a hydrothermal method was characterised by BET, XRD, TGA-MS and in situ variable temperature diffuse reflectance infra red spectroscopy (DRIFTS) to determine the surface behaviour of water. For the (100) facets, hydrogen bonding does not occur, and water adsorption is less strong than for the (111) and (110) facets where hydrogen bonding does occur. Reversible uptake of oxygen was observed.

Determination of Mercury Exposure among Dental Health Workers in Nakhon Si Thammarat Province, Thailand.

Objectives. The main objective of this study was to assess the mercury exposure levels in dental health workers that work in dental clinics. The study evaluated the airborne and urinary mercury levels, the type of work done in the clinic, and the effect of mercury exposure on health of dental health workers.
