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

Abstract

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)

Corrosion effect on the flexural strength & micro-hardness of ips e-max ceramics

“…Flexural strength of the ceramic material is an important factor for the success of any fixed restorations [9]. Flexural strength test are preferred to diametral compressive test because they more closely simulate the stress distribution in the dental prostheses.…”

Effect of light intensity and irradiation time on the polymerization process of a dental composite resin

“…Gaps may occur at the interface between the restoration and the remaining tooth structure when the enamel or dentine bond strength is inadequate to withstand the polymerization contractile stresses. This phenomenon may cause post-operative pain, marginal microleakage and secondary caries, which are the predominant reason for replacement of composite resin restorations [8][9][10] . If the bond strength is adequate, the contraction stress is transmitted to the remaining tooth structure and may result in enamel microcracks and cuspal deflection 7 .…”

Finishing and Polishing Procedures of Composite Restorations by Saudi Dentists: A Cross-sectional Study

“…A Dutch study concluded that, staining or discoloration was one of the primary reasons for replacement of composite restorations. 6 Similarly, 174…”

“…2,3 Staining or discoloration is one of the most common reasons for replacement of composite restorations 4 and most of the published reports document that the finish, surface roughness and surface integrity of the restoration, as well as the physicochemical properties of the material itself can influence plaque adhesion and retention and staining of the composite resin. 5,6 The dental practitioners' knowledge and attitudes toward the oral health care provide the frame work for their professional work. 7 Dentists' treatment decisions are influenced by their knowledge toward care options, and assessing these is worthwhile.…”
