Reader Abstract Service ALLISON, R. T.. and DOUGLAS, W. H. Micro-colonization of the denture-fitting y$roe by Candid8 albicsns, J. Dent., 1 (1973).

ABSTRACT The denture-fitting surface of two soft lining materials and one acrylic denture from 3 patients with denture stomatitis were examined by light and scanning electron microscopy. The lining material showed overgrowth of the fitting surface by Candida albicans hyphee; the acrylic denture showed a surface plaque in which organisms could be identified.

ABSTRACT Two aspects of the use of silicate cement have been examined. Experiments were carried out, using dental students, to illustrate the wide variation that can occur in the subiective assessment of the shade

of teeth. Also, the constancy of shade of a pro- prietary silicate cement was investigated using a reflectometer develooed for the specific ouroose of measuring off-white colours. A satisfactory uniform- ity of colour between batches of cement was con- firmed. A need for guidance of students in shade selection was indicated. REFERENCES Judd, D. B., and others (1937). J.

Preventive treatment of fissure caries, .I. Dent., 1 (1973). 207. ABSTRACT A trial of a simple means of reducing caries in fissures is described. Petralit was applied to first permanent molars on one side of the mouth; a marked reduction in caries was ob- served after approximately 2 years. Some factors

The requirements for materials which can prevent fissure caries are discussed and related to the properties of materials available at present. Two different tvpes of material are recoanired on the basis oftheir permeability, and the indkationsfor use are considered to be determined principally by the caries susceptibility of the patient.

ABSTRACT A survey has been carried out to assess the value of denture fixatives in complete denture wearers. The masticatory performance of each subject was measured, with and without the use of a denture fixative. The value of the fixative was found to increase as the quality of the dentures deteriorated.
