Pesticide poisoning has indeed been recognized as a significant global health problem, and it is the most common cause of morbidity and mortality. Organophosphorus compounds (OP) are extensively used in agriculture, omestic pest control, and biological agents. Each year, an estimated 25 million farmers in developing countries are poisoned by pesticides, commonly OP, which is known to cause serious health ill effects.
To assess the histomorphological alterations in natural tooth due to exposure to different organophosphorus compounds.
This research was carried out with organophosphorus compound - PHOSKILL, insecticide, purchased from local commercial market. The natural tooth were immersed in the respective solution for an hour and assessed for morphological & histological alterations through ground sections (200μm).
Visually, mild colour changes were noted on the tooth external surface, especially on the root surface. This yellow orange tint noted of the tooth surface could be because of the concentration of the dye added to the OP compound. The structure and the morphology of the tooth remain undisturbed. Morphologically, the incremental lines of retzius are brownish bands found due to the successive apposition of layers of enamel during formation. There are also few hypocalcified structures evident. The dentinal tubules and interglobular dentin are more prominent in this current ground section and the pulpal tissue was completely lost in OP compound exposed tooth.
The OP compounds did not prove to show any morphological or histological alterations to natural tooth.
