Survey of prosthodontic impression procedures for complete dentures in general dental practice in the United Kingdom.

STATEMENT OF PROBLEM: Anecdotal evidence suggests impression techniques used in general dental practice may vary from those taught at dental schools. There is little published information on this topic. PURPOSE: This study identifies the materials and methods used by general dental practitioners for recording impressions for the provision of replacement of complete dentures. METHODS: A total of 905 questionnaires were sent to general dental practitioners in the Greater Manchester area to identify current clinical practices. RESULTS: The results revealed that 88% of respondents use only irreversible hydrocolloid for primary impressions. If multiple responses are included, 99% of respondents mentioned irreversible hydrocolloids as an option for primary impressions. In response to the same question for secondary impressions, 94% of respondents mentioned irreversible hydrocolloids as an option. Other material mentioned as an option for secondary impressions included zinc oxide-eugenol (29%) and polyvinyl siloxane (13%). With regard to special trays, 75% of respondents routinely used laboratory constructed special trays to take definitive impressions. Questions on the requisite spacing, perforation, handle design of special trays, and on disinfection showed a diversity of opinion among practitioners. CONCLUSIONS: Although this survey reflected a diverse range of clinical preferences, it is clear that irreversible hydrocolloid dominates the impression market for complete dentures. The use of special trays is normal practice for complete dentures in general dental practice in the United Kingdom.

Gender aesthetics in the natural dentition.

This paper questions whether the size, position and angulation of upper anterior teeth 'reflect' the gender of a patient. Forty-six casts of natural teeth were given to 11 experts. The experts were asked to assess the gender of the patients. Overall the intra-observer agreement was fair (kappa = 0.33). Inter-observer agreement was fair (kappa = 0.23). On average 55% of casts taken from men were classified as 'male' and 55% of the casts taken from women were classified as 'female'. It is concluded, on the basis of this study, experts can not distinguish gender by the visual assessment of upper anterior teeth on casts alone.

Case report: the high proximal survey line.

This case report demonstrates a method of adding composite to a tooth to move a high survey line closer to the gingival margin. The purpose of this modification is to facilitate clasping.

Extraction forceps for small hands.

This paper discusses the problems encountered by small handed dentists when extracting teeth using standard forceps. An alteration in the design of standard upper forceps is proposed which will be advantageous to small handed dentists. The new design is 'open bladed', that is, when the handles are closed the blades are manufactured to be 5 mm apart.

A reattachment technique for fractured incisor tooth fragments: a case history and discussion of alternative techniques.

This paper describes the case history of a patient for whom two fractured central incisor fragments were reattached using an acid etch technique. The case demonstrates a method, which has not been reported previously, using pins to reinforce the attachment. Finally the case shows the failure of the reattachment on one central incisor and subsequent successful treatment by the use of a veneer crown.

T-cell prolymphocytic leukemia with helper-cell phenotype and a review of the literature.

The majority of published cases of prolymphocytic leukemia (PLL) have been of B-cell origin. Nineteen cases of PLL of T-cell type have been described, as has a single case of PLL having a surface phenotype with features of both B-cells and T-cells. This report presents a review of these cases and comparison with one case of T-cell PLL. By using specific monoclonal antibody technique, this case was subcategorized into helper-cell phenotype: E-rosette(+), SIG(-), Anti-T(+), Anti-B(-), Anti-monocyte(-), OKT3(+), OKT4(+), OKT6(-), OKT8(-), Ia(+), and Tdt(-). Cytochemical studies showed paranuclear acid phosphatase granules. Postmortem examination revealed a predominant T-cell zone infiltration by the leukemic cells in the spleen and lymph nodes, with involvement of multiple organs. The application of the monoclonal antibody technique, which can be standardized among different laboratories to subclassify lymphoproliferative disorders into functional subtypes, should lead to a better understanding and more effective treatment of this disease.
