ABSTRACT
Intrusion of immature permanent anterior teeth presents a great dilemma due to variety of treatment options. The ideal treatment option is the one with least probability of developing complications like external root resorption, obliteration of pulp canal, marginal bone loss etc. This paper presents a case report with treatment strategy of repositioning, splinting, successfully attempted apexification and obturation of a completely intruded immature permanent central incisor. Excellent healing with no post-operative complications even after 10 months of follow up.

Technical hexachlorocyclohexane (HCH, 100 mg/kg/day) and oxydemeton methyl 25 EC (125 mg/kg/day) to female rats for 7, 15 and 30 days individually and in combination through skin application caused pathomorphological changes in vital organs and significant enzymatic changes in liver and serum. However changes produced by the two compounds in combination were not suggestive of potentiation effect at the tested dose level in female rats.

Application of HCH (25 mg/kg) on dorsal, ventral and thigh regions of the skin of male rabbits resulted in poisoning and mortality of animals. Morphological changes in skin, liver, kidney, testes and cerebellum together with highly significant alterations in serum and liver enzymatic activity and residue in blood suggested that absorption of HCH and its toxicity could be severe when the pesticide comes in contact with the skin of thigh region of body.
