Quantitative Analysis of Phytoconstituents of Hydroalcoholic Extract of Carica Papaya Leaf

Carica papaya (C. papaya) leaves have been used in folk medicine for centuries. Several reports are available for use of Carica papaya leaves in increasing blood platelet count in dengue hemorrhagic fever. Recent studies also reported that Carica papaya leaves exhibits anti-tumor activity and immunomodulatory effects. Papaya leaf extract is reported to contain carbohydrates, amino acids, sterols, saponin glycosides, iridoids, flavonoids, phenolics, anthraquionones, triterpenes and alkaloids. The present investigation demonstrates the concentration of secondary metabolites in the hydroalcoholic extract of Carica papaya leaves. The total phenolics, total alkaloid and total flavonoid content were calculated by Folin–Ciocalteu colorimetric method, Bromocresol green colorimetric method and aluminum chloride colorimetric method respectively

Survey of current materials and impression techniques for Complete Dentures among Nepalese Prosthodontists

ABSTRACTBackground: Impression making is one of the critical factors in determining success or failure of complete denture therapy. The precise reproduction of edentulous foundation is essential for retention, stability, and support of the removable prosthesis. Evidence suggests that there is variability in materials and techniques regarding impressions making for complete dentures. There is little published information on studies conducted among Nepalese Prosthodontists. The purpose of this study was to evaluate current materials andmethods for impressions for complete denture prosthodontics in Nepal. Materials &amp; Methods: A questionnaire based survey was conducted among Nepalese Prosthodontists. Ethical approval for the beginning of the study was obtained via Institutional Review Committee, Nepal Medical College. A self-administered anonymous questionnaire was distributed to the participants. Data were analyzed by using frequency distribution.Results: Majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. The selective pressure was the predominantly used impression philosophy (78.3%). The most common material for the fabrication of custom trays was autopolymerizing acrylic resin (96.7%). All respondents border molded the custom tray prior to making the final impression. The final impression materials used were zinc oxide eugenol impression paste (73.3%), polyvinylsiloxane (11.7%), polyether (11.7%) and polysulphide (3.3%). Conclusion: Although there is variability in impression materials andtechniques used by Prosthodontists in Nepal for the fabrication of complete dentures, the results showed interesting trends. Most practitioners followed the traditional techniques of complete denture impression procedures.Keywords: complete denture; custom tray; edentulism; impression. </p
