Canine guidance on crowned teeth: time for a rethink?

This paper aims to discuss the concept of canine guidance in light of recent research with regard to time to extraction of the restored canine tooth, with crowns representing the worst performing restoration at 15 years (66% cumulative survival). Given that the upper canine tooth may be considered the 'cornerstone' of the arch, reasons for this poor performance are discussed by examination of the existing literature on canine guidance and other aspects relating to the preparation of an upper canine tooth for a crown. The authors question previous recommendations that canine teeth should be placed into canine guidance when restored with crowns, given that the previously-published data indicate that survival of upper canine teeth which have been crowned is worse than when they are restored with any other restoration.

Patient history as a predictor of future treatment need? Considerations from a dataset containing over nine million courses of treatment.

Aim It is the aim of this paper to consider whether overall patient treatment history per se and what length of patient history, matters in predicting future treatment need.Methods This study used a data set (SN7024, available from UKDataService), consisting of treatment records for General Dental Services' (GDS) patients, this being obtained from all items of service payment records for patients treated in the GDS of England and Wales between 1990 and 2006. For the purpose of this study, the GDS dataset for patients attending in 2003 was restricted to adult patients (aged 18 or over on 31 December 1990; that is, year of birth earlier than 1973) who attended in both two-year periods 1991/2 and 2004/5.

The ultimate guide to restoration longevity in England and Wales. Part 10: key findings from a ten million restoration dataset.

Introduction: This paper defines key points from a ten million restoration dataset in order to compare and contrast the data from the previous nine papers, identifying common themes and/or differences in the factors affecting the survival of restored teeth to next intervention or extraction.

Aim: It is the aim of this paper to present data on the survival of restorations in teeth by analysis of the time to re-intervention on the restorations and time to extraction of the restored tooth, and to discuss key findings regarding this.

Methods: A data set was established, consisting of General Dental Services (GDS) patients, this being obtained from all records for adults (aged 18 or over at date of acceptance) in the GDS of England and Wales between 1990 and 2006.

The ultimate guide to restoration longevity in England and Wales. Part 9: incisor teeth: restoration time to next intervention and to extraction of the restored tooth.

Aim: It is the aim of this paper to present data on the survival of restorations in incisor teeth by analysis of the time to re-intervention on the restorations and time to extraction of the restored incisor tooth, and to discuss the factors which may influence this.

Methods: A data set was established, consisting of General Dental Services patients, this being obtained from all records for adults (aged 18 or over at date of acceptance) in the GDS of England and Wales between 1990 and 2006. The data consist of items obtained from the payment claims submitted by GDS dentists to the Dental Practice Board (DPB) in Eastbourne, Sussex, UK.
