“…29,30 Calibration of the single assessor was carried out and several cases were scored by a consultant in restorative dentistry to ensure correct application of the criteria. Modified United States Public Health Services (USPHS) criteria [31][32][33] were used (Table 1) and the data was entered on a spreadsheet run by the software Statistical Programme for Social Sciences (SPSS).…”

Objective To examine the clinical performance of resin-based composite restorations placed at an increased vertical dimension when used to manage localised anterior tooth wear. Design A retrospective analysis of cases treated at a single centre. Setting UK Hospital setting in the year 2000. Subjects and Methods Two hundred and twenty five restorations placed in 31 subjects were included. Assessment was made following examination of study casts and projected slides. Modified United States Public Health Services criteria were used and data analysed using the software Statistical Programme for Social Sciences (SPSS). Survival analysis was carried out at two levels, major failure only and all types of failure. Kaplan-Meier survival plots were produced against different variables and modes of failure were also noted. Results Major failure requiring replacement of the restoration was uncommon within the first five years. Minor failure requiring repair or refinishing presented mainly as wear, marginal discolouration or marginal fracture. Median survival was 4 years 9 months when all types of failure were considered. The restorations have good appearance and are well tolerated. Conclusion Placement of resin-based composite restorations at an increased vertical dimension to treat localised anterior tooth wear, has good short to medium term survival. The technique is conservative and relatively easy to maintain.Tooth wear appears to be an increasingly significant problem affecting all ages. 1,2 In particular there is an increased incidence of young patients presenting with moderate to severe, erosive wear caused by intrinsic and extrinsic acids. [3][4][5] Erosion is the most significant cause of tooth wear and has been implicated in 89% of all cases. 6

“…Although a categorical scale was used in the present study, the principle o( ranking impressions should be identical with ranking photographs. The disadvantage of using rating scales is that considerable variation in ratings for the same restorations may be given by different assessors (55,56). Some investigators therefore consider measuring the degree of conformity in classifying each restoration unnecessarily rigorous for validating a method or measuring the interexaminer agreement (57).…”

The study aimed to validate the scoring of the degree of marginal degradation of amalgam restorations by using impressions, as an alternative to other indirect scoring methods using photographs or casts. Ten-year-old condensation silicone elastomer impressions and epoxy replicas made in 1979 were compared in a scanning electron microscope at 5 kV with different magnifications up to x200. The impre~sion material was not distorted or degraded, and the dimensional stability was good after 10 years of storage in a dry environment. The interexaminer agreement of the scorings of impressions and a six-point scale reference set was satisfactory as evaluated by kappa statistics, demonstrating that degrees of marginal degradation can be distinguished on impressions with relatively high accuracy. The rating distribution of the scorings of impressions showed good correlation to the rating distributions obtained with the clinical USPHS rating method and with photographs for recording marginal degradation. A slight difference between the photographic and impression ratings at the upper and lower levels of the six-point rating scale was observed. The difference varied with the type of alloy, possibly due to a bias depending on the surface quality-that is, whether the restoration kept the glossiness of high polishing or became heavily tarnished. 0 Amalgam degradation; clinical rating; clinical study; kappa statistics; silicone elastomer AsbjomJokstad,

“…These data were easily retrievable from the Health Management Information System (HMIS). It is known that proper treatment planning, restorative treatment decisions and procedures and good filling materials are fundamental for a lasting filling (Elderton, 1977). Repeat cycles of restoration (filling) can ultimately lead to tooth mortality.…”
