An Audit Of The Turnaround Time Of Fixed Prosthodontics Cases In The Ceramic Laboratory

This clinical audit is aimed to provide an insight into the performance of dental technicians in renderingfixed prosthodontics services at Faculty of Dentistry, University of Malaya. A retrospective audit wascarried out between 1st of November 2014 and 31st January 2015 using data derived from records andmonthly returns of the technicians, which are kept at the ceramic laboratory. Retrospective data oncases of diagnostic wax-ups, full metal crowns, metal ceramic crowns, all ceramic crowns and bridgesthat were sent to ceramic laboratory for fabrication from 1st of September 2013 to 31st of August 2014was systematically extracted from the record and tabulated categorically in SPSS version 22.0. Theturnaround time in workings day for diagnostic wax-ups and the prostheses was calculated by deductingexit date from entry date. Subsequently, the turnaround time and the complexity of cases were categorizedaccordingly. The association of turnaround time and the complexity of the cases was analysed usingFisher Exact test with p value < 0.05. Within this time frame, a total of 102 cases of diagnostic waxups,36 cases of crown and 18 cases of bridges were fabricated. 57.8% of diagnostic wax-ups werecompleted within 3 days. 100% of 1 unit crown were completed within 7 days and 94.4% of bridges werecompleted within 14 days. There was a significant association of turnaround time and the complexity ofthe cases for diagnostic wax-ups and crowns with p value <0.05. The standard for turnaround time isbeing met by the ceramic laboratory at Faculty of Dentistry, University of Malaya. However, due to theexcessive workload, the overall output of all the measured procedures remains low.

Yellow nail syndrome: a rarity in Indians?

Reports of yellow nail syndrome have been few and far between. The classical triad of the syndrome has not been reported in Indian literature. We report a case of yellow nail syndrome in a forty-year-old male, who had yellowish-brown nails from birth. He developed lymphoedema of the legs at the age of twenty years and presented with pleural effusion at the age of forty years. Although a case of yellow nail syndrome has been reported from India, the classical triad of the syndrome is yet to be documented from our country. The condition may be missed because of the long time difference in presentation of different components of the syndrome and also because of the dark skin colour of Indians.

Laboratory assessment of indigenous plant extracts for anti-juvenile hormone activity in Culex quinquefasciatus.

Of 15 plants tested, five plant extracts showed anti-juvenile hormone-like activity against laboratory colonised late fourth instar larvae and adult female mosquitoes. Petroleum ether extract of Eichhornia crassipes and acetone extracts of Ageratum conyzoides, Cleome icosandra, Tagetes erectes and Tridax procumbens showed growth inhibitory (P less than 0.001) and juvenile hormone mimicing activity to the treated larvae of C. quinquefasciatus.. Larval pupal intermediates, demalanised pupae, defective egg rafts and adult with deformed flight muscles were few noticeable changes. Biting behaviour was observed to be affected only in Ageratum, Cleome and Tridax extracts (P less than 0.001). Loss of fecundity was observed in the treated mosquitoes but no sterilant effects could be seen. Adults, obtained from larvae exposed to the plant extracts produced significantly shorter egg-rafts (P less than 0.005) than in control.
