“…In adults, replacement of failed restorations comprised 60±80% of all restorations inserted in the 1960±80s (7,14,15,20,21), which is in conformity with present findings. Recent data from Sweden indicate that this proportion has diminished to about 50% (4,13).…”

In this study, we recorded the type of restoration and the materials used in 24,429 restorations in permanent teeth by 243 Norwegian clinicians in general practice. Demographic information included patient's gender and age, and clinician's gender, years since graduation, and practice setting (private or salaried). The overall recorded use of restorative materials in permanent teeth shows that 32% are amalgams, just over 40% composites, and about 25% glass ionomer type materials. Three percent are "other" materials. A marked shift away from amalgam restorations is noted both in the clinician's estimated use during the last 2 decades and by comparing the present use of materials with that in failed restorations. Tooth-colored materials are more commonly used in adolescents, especially glass ionomer materials, and in female patients. In patients < or = 18 years, amalgam is used in 25% of all restorations. The use of amalgam is similar in private practice and in public health service practice, but private practitioners use more composites and salaried dentists more glass ionomers. The clinician's gender does not have any effect on the selection of restorative materials. The change from amalgam to tooth-colored material is particularly noticeable for Class I and Class V restorations. Amalgam is the predominant material in 2- and 3-surface Class II restorations.

“…Because of technical developments-such as modern alloys and composites-and changes in patient-related factors, such as use of fluoride, studies from about 20 years ago (Moore and Stewart, 1967;Allan, 1969) are no longer representative of the present situation. They cannot be used for comparison with results from the present study.…”

“…In the present study, 23.3% of the restorations (n = 8050) were assessed as unsatisfactory. Moore and Stewart (1967) found that 45% of all restorations (n = 8482) investigated in 907 patients needed to be replaced. This trend is also reflected in investigations by Allan (1969), Goldberg et al (1980), Richardson and Boyd (1973), Mjor (1981), Skogedal and Heloe (1979), and in a literature review by Elderton (1976).…”

Prevalence and Need for Replacement of Amalgam and Composite Restorations in Dutch Adults

et al. 1990

In 1986, the first nationwide epidemiological survey of adult oral health and attitudes to oral health care was carried out in The Netherlands. One of the aims of this study was to evaluate the prevalence and the quality (in terms of need for replacement) of amalgam and composite restorations in the Dutch adult population. A group of 600 dentate individuals, 20-44 years of age, was examined. Stratified cluster sampling included as factors age, gender, socio-economic status, and area of residence. Two additional parameters were studied: frequency of visiting a dentist and type of health insurance. Oral examinations consisted of direct (mirror and explorer) and indirect (color slides and bite-wing radiographs) observations with use of well-defined criteria. On average, 13.4 restorations per individual were present, of which 23.3% were classified as unsatisfactory. A great difference in prevalence and quality data was found among several types of restorations. Test results (ANOVA) for effects of age, gender, socio-economic status, area of residence, frequency of visiting a dentist, and insurance on the prevalence of (un)satisfactory restorations resulted nearly always in significant effects of only age and frequency of visits to a dentist. There was a tendency (p less than 0.05) for the prevalence of (un)satisfactory restorations to be higher with increasing age.(ABSTRACT TRUNCATED AT 250 WORDS)

“…For this reason marginal integrity is one of the principal criteria used for judgment of restoration quality (Mahler et al, 1970;Cvar and Ryge, 1971;Elderton, 1977;Smales and Creaven, 1985), and many restorations have been replaced because of defective margins, rather than because of evidence of caries (Healey and Phillips, 1949;Moore and Stewart, 1967;Barnes et al, 1973;Bailit et al, 1979;Mjor, 1981). It is widely believed that recurrent caries is largely the result of marginal failure of restorations (Goldberg et al, 1981), to the extent that the replacement of such defective restorations has become common dental practice as a preventive procedure.…”

The Caries Status of Occlusal Amalgam Restorations with Marginal Defects

The purpose of this study was to examine histologically occlusal amalgam restorations with both defective and sound margins for comparison of their caries status. Thirty extracted teeth with occlusal amalgam restorations were sectioned so that a ditched and a clinically sound margin could be examined on the same tooth in the mouth. Histological examination showed a low prevalence of caries lesions in the outer enamel. However, lesions were present in the enamel of the cavity wall in 54% of specimens, whether the margin was defective or sound. If the results of this study are applicable to all occlusal amalgams with defective margins, it would appear that a defective margin alone is not an indication that a restoration needs to be replaced.
