“…[1][2][3][4][5][6][7][8][9][10] The results of a recent systematic review 23 on the longevity of dental restorations in the primary and permanent dentition are shown in Figure 5. When compared with these data, the reported survival rate of the Hall technique (73.4% after three years and 67.6% after five years) would seem better than those reported for glass ionomer materials and broadly equivalent to those reported for composite materials.…”

“…Evidence from clinical trials indicates that conventional restorative techniques using amalgam, composite or compomer materials can be successful. [1][2][3][4][5][6][7][8][9][10] However, the majority of these trials were carried out in either secondary care or specialist private practices. A recent evaluation of restorations placed by general dental practitioners in the UK found far less favourable results 11 and, in fact, the justification and desirability of even attempting restorative management of carious primary teeth in general dental practice has been questioned.…”

A novel technique using preformed metal crowns for managing carious primary molars in general practice — A retrospective analysis

BackgroundThere is a high level of untreated dental decay in primary teeth in Scotland. Despite evidence for the efficacy of preformed metal crowns (PMCs) for the restoration of primary molars, few are placed in general practice, possibly due to the interventive nature of the clinical procedure. There is, however, a novel way of placing PMCs involving no local anaesthesia, no caries removal and no preparation of the tooth: the Hall technique. Aim To investigate the survival of carious primary teeth treated with PMCs placed using a novel, simplified method -the Hall technique. Setting General dental practice, in Scotland. Methods A retrospective analysis of practice records from one general practitioner, from 1988 to 2001. The majority of the 978 PMCs fitted on 259 children, using the Hall technique, were placed when there was clinical evidence of approximal caries into dentine. The Kaplan-Meier approach was used to analyse survival times and the Mantel-Haenszel Log rank test for comparison between tooth types. Results For all tooth types, the probability of surviving three years without being extracted or the PMC being lost, was 73.4% (95% confidence interval 70.1% to 76.4%), and for five years was 67.6% (95% confidence interval 63.3% to 71.5%). The probability of surviving without extraction alone for three years was 86.0% (95% confidence interval 83.2% to 88.4%), and for five years was 80.5% (95% confidence interval 76.5% to 83.9%). Conclusion Hall technique restorations placed on primary molars with decay clinically into dentine, by a single operator in general dental practice, have a similar success rate to some other, more conventional, restorative techniques. The technique requires further evaluation through a prospective randomised control clinical trial before its use could be generally recommended.

“…Figure 2 shows the survival curve produced from combining results from 1991 3 (Ketac Fi1: ESPE GMbH, Seefeld/Oberbay, Germany). The MST for Ketac Silver must be interpreted in the light of the fact that a large proportion of restorations were 'censored' ie they survived intact at the end of the 2.5 year trial.…”

“…4 Glass ionomer cements, despite having a lower mean survival time compared with amalgam, provide a means of restoring primary molars with minimal destruction of tooth tissues. 3 The search for improvements to the mechanical properties of glass ionomer cements led to the incorporation of light cured resin components to give 'resin modified glass ionomer cements' and subsequently 'poly acid modified resin composites' or 'compomers' .…”

Clinical evaluation of paired compomer and glass ionomer restorations in primary molars: final results after 42 months

T echniques used to restore primary molar teeth have changed over the past decade as new adhesive materials have been developed. Stainless steel or nickel chrome preformed crowns provide the most durable restoration, often surviving until the tooth exfoliates. 1 The durability of other restorative materials are usually compared with dental amalgam. Composite resins in the short term are as durable as amalgam but after 6 years have a failure rate of 62% compared with 20% for amalgam after 5 years. 2 Conventional glass ionomer cements on the other hand only have a mean survival time of 33 months compared with 41 months for amalgam.

It was disappointing that only three trials that compared three different types of materials were suitable for inclusion into this review. There were no significant differences found in all three trials for all of the outcomes assessed. Well designed, randomised controlled trials comparing the different types of filling materials for similar outcomes are urgently needed in dentistry. There was insufficient evidence from the three included trials to make any recommendations about which filling material to use.
