Rehabilitation Of A Patient Having Few Natural Teeth With Maxillary Overdenture –A Clinical Report

The over denture, a complete or partial denture prosthesis constructed over existing teeth or root structure is not a new concept in a technical approach to a prosthodontic problem. Today with the stress on preventive measures in prosthodontics, the use of over dentures has increased to the point where it is feasible alternative to most treatment plan outlines in the construction of a prosthesis for patients with remaining teeth. Here a 54 years male patient  is rehabilitated with fabrication of maxillary over denture with copings and mandibular removable complete denture. Key words: Over denture, Cast metal copings, Maxillary arc

Assessment of the Effects Following Subchronic Dosing with Sodium Tungstate on Male Reproductive System in Wistar Rats

Sodium tungstate is one of the inorganic compound with insulinomimmetic properties. The present study was conducted to investigate the effects of sodium tungstate on male reproductive system. The experimental rats were randomly divided into two groups (n=8/ group). The first group was used as a control, the second group was used to study the effect of sodium tungstate. Sodium tungstate was orally administrated to male Wistar rats at a dose level of 50mg/kg.bd wt. /day for 60 days. The daily administration produced no significant changes in the body weight gain. No significant changes were observed in the weight of testis, epididymis, seminal vesicles, ventral prostate, liver, kidney, and adrenal gland. Exogenous  supplementation with Sodium tungstate produce non significant depletion in protein, glycogen and sialic acid content in testis and epididymis and fructose level in seminal vesicle. Cholesterol level showed  no significant change in testis and epididymis. However, Spermatozoon motility and epididymal sperm concentration showed no significant changes. Plasma testosterone, FSH and LH level showed non significant decline in the sodium tungstate treated animals when compared to the control animals.The histology of testis and cauda epididymis showed no severe histological alterations when compared to control group. The results conclude that sodium tungstate (50 mg/kg bd.wt./day) did not cause any severe histological and biochemical alteration in male reproductive system
