Amalgam and composite use in UK general dental practice in 2001.

OBJECTIVE: This study determined the reasons for dentists' choice of materials, in particular amalgam and resin composite, in Great Britain. METHOD: A questionnaire was developed to elicit this information. The names and addresses of 1,000 UK-based dentists were selected at random. The questionnaire was mailed to these dentists with an explanatory letter and reply-paid envelope. RESULTS: Six hundred and fifty four replies were received. Regarding choice of material, 100% of respondents cited clinical indication as the most influential factor, although patients' aesthetic demands (99%), patients' choice (95%) and patients' financial situation (92%) were also reported to influence respondents' choice. Thirty-five per cent of respondents used composite 'sometimes', 15% 'often', and 1% 'always' in extensive load-bearing cavities in molar teeth. For composite restorations in posterior teeth, 92% 'always', 'often' or 'sometimes' used the total etch technique and 53% never used rubber dam. Seventy per cent of respondents agreed with the statement 'discontinuation of amalgam restricts a dentist's ability to adequately treat patients'. Eighty-one per cent considered that the growth in the use of composites increased the total cost of oral healthcare. CONCLUSIONS: Forty nine per cent of the respondents from England and Wales seldom or never place large composite restorations in molar teeth. Their choice of material is influenced greatly by clinical indications, and patients' aesthetic demands.

Trends in self-reported use of dental services among Finnish adults during two decades.

OBJECTIVE: To analyse trends in the prevalence of and determinants for dental care utilisation among Finnish adults of working age during two decades. BASIC RESEARCH DESIGN AND PARTICIPANTS: The National Public Health Institute has, since 1978, conducted annual surveys of health behaviour among the whole Finnish adult population (aged 15-64 years). Data collected through mailed questionnaires have included questions on dental utilisation. Sample sizes have varied from 5,000 to 6,000 and response rates from 68% to 85%. RESULTS: The use of dental services increased in the period 1978 to 1997 from 53% to 64% (P<0.001) of the population. Women and persons belonging to the younger age groups were the most frequent visitors, and older persons the least frequent due to the greater prevalence of edentulousness. During the period, differences in the use of services associated with region, level of education and occupation declined. During the first decade, a clear increase in dental utilisation was found in younger age groups and during the latter decade in older age groups. Significant predictors for the utilisation of services were the number of missing teeth, age, gender, occupation and toothbrushing frequency in 1997. CONCLUSIONS: The utilisation of dental services has increased slowly since 1978 but remains lower than in other Nordic countries. In a country where the supply of services is abundant, the major determinant of the use of services is the number of teeth an individual has.
