Influence on dimensional accuracy of volume of wash material introduced into pre-spaced putty/wash impressions.

This study compared the accuracy of stone models obtained from two-stage, pre-spaced putty/wash impressions under conditions in which known volumes of wash material were introduced during the second stage of the impression: Group I, a quantity of wash material corresponding to the space provided; Group II, double the quantity of wash material as the space provided; Group III, double the quantity of wash material, but with V-shaped vents in the putty for escape of excess material. Percentage deviations of the vertical dimensions of stone dies with respect to the master model were significantly different between Groups I and II (the latter being shorter) (p < 0.05).

Sentiments expressed in relation to tooth loss: a qualitative study among edentulous Saudis.

Purpose: The objective was to explore and gain insight into the sentiments surrounding tooth loss in a group of edentulous Saudis.

Materials And Methods: Using a qualitative methodology, 44 edentulous patients who were receiving complete denture treatment were interviewed in private, in the Arabic language. Interviews were tape recorded and semistructured, following a list of predetermined and piloted topics, but dialogue also took place, with the freedom for both interviewer and interviewee to explore areas of interest.
