The purpose of this study was to report on the 7-year follow-up of 15 patients who took part in a prospective randomised controlled split-mouth trial to evaluate the performance and patient satisfaction of 107 direct composite restorations bonded to their worn anterior mandibular dentition. This is the continuation of a study by Poyser et al., which investigated the performance of the same direct composite restorations on this cohort of patients at 2.5 years. The results of the present study suggest that direct composite restorations bonded to the worn anterior mandibular dentition to have an approximate survival of 85% at the 7-year follow-up. Approximately 53% of patients experienced survival of all of their restorations. Pre-operative circumferential preparation did not influence restoration survival, patient satisfaction or other clinical variables (restoration staining, marginal discolouration, shade match, surface roughness and marginal adaptation). The time taken to initially build-up the restorations was shown to be statistically significant with a longer procedural time meaning less chance of the restoration being present at 7 years. This treatment modality exhibited no biological complications for the teeth, supporting periodontium or TMJ apparatus. The placement of these restorations provided an improvement in the aesthetics of the teeth, a reduction in the concern over the longevity of the worn lower anterior teeth, and improvements with regard to sensitivity experienced with hot or cold foods or drinks. Marginal breakdown was the most frequently recorded clinical complication. Thus, for the majority of patients, the restorations offered a high degree of patient satisfaction and required an acceptable level of maintenance in the 7-year follow-up period.

The replantation of avulsed primary incisors is contra-indicated. This case describes an 8-year-old child who six years previously had avulsed and had replanted a primary central incisor. At presentation, this tooth was retained, the permanent successor had failed to erupt and appearance of the adjacent lateral incisor was notably delayed. Investigation revealed a radicular cyst in relation to the replanted deciduous incisor together with severe displacement of the permanent tooth, which could not be saved.

When individuals are given dental implants, are there different success rates for immediately/ early-loaded implants compared with conventionally loaded implants?Esposito M, Grusovin MG, Willings M, Coulthard P, Worthington HV. Interventions for replacing missing teeth: different times for loading dental implants. Cochrane Database Syst Rev 2007; issue 2Data sources The Cochrane Oral Health Group's Trials Register, Cochrane Central Register of Controlled Trials, Medline and Embase were searched. Handsearching included several dental journals. Authors of all identified trials, an internet discussion group and 55 dental implant manufacturers were contacted to find unpublished randomised controlled trials (RCT). Study selection RCT were selected of root-form osseo-integrated oral implants that had a followup of 6 months-1 year and which compared the same osseo-integrated root-form implants immediately (within 1 week), early (1 week-2 months) and conventionally loaded (after 2 months), giving the following outcome measures: failures, implant failures and marginal bone levels on intra-oral radiographs. Data extraction and synthesis Data were independently extracted, in duplicate, by two review authors. Authors were contacted for details of randomisation and withdrawals and a quality assessment was carried out. The Cochrane Oral Health Group's statistical guidelines were followed. Results Twenty RCT were identified and 11 trials comprising a total of 300 patients were included. Six trials compared immediate versus conventional loading, three early versus conventional loading and two immediate versus early loading. On a patient, rather than per implant basis, there were no statistically significant differences for any of the meta-analyses. Conclusions It is possible to successfully load dental implants immediately or early after their placement in selected patients, but not all clinicians achieve optimal results when loading the implant immediately. A high degree of primary implant stability (high value of insertion torque) seems to be one of the prerequisites for a successful immediate/ early loading procedure. More well-designed RCT are needed. Priority should be given to trials comparing immediately versus early loaded implants to improve patient satisfaction and decrease treatment time and trials should be reported according to the CONSORT guidelines (http://www. consort-statement.org/). CommentaryTo date, there has been limited systematic comparison of the effect of the timing of implant loading on failure rates. Experience and anecdotal opinions favour a conventional approach to implant loading, but currently it seems popular to attempt to complete treatment in the shortest period of time: immediate and early loading have therefore been suggested. The authors of this article deserve credit for investigating such a contentious aspect of implantology.Rigorous searching resulted in 20 RCT being identified, of which 11 were eventually included. Both published and unpublished literature have been looked at in this rev...
