Clinical evaluation of Scotchbond: three-year results.

In a previous paper, the one-year retention of composite resin in non-undercut Class V abrasion lesions mediated by self-cure Scotchbond dentine bonding agent without enamel etching was reported. The present paper reports the three-year results. Initially, a total of 310 restorations was placed using Silux, Silar, Ketac-Fil and Fuji II. The percentage cumulative loss of the restorations at two and three years, respectively, was: Silux 27, 30; Silar 58, 58; Ketac-Fil 0, 0; Fuji II 4, 14. Over the total study period, there was a high loss rate of composite restorations in the first six months, and a tendency to increased loss over one to three years. There was a significant increase in marginal discoloration, assessed photographically, over the three-year period, and caries was present around some restorations.

Caring for the dentate elderly.

The proportional increase of elderly persons in most communities and increasing tooth retention among them betoken considerable change in gerodontic needs. Servicing dentate older patients will occupy progressively more practising time. This committment requires the development of somewhat different skills, knowledge and philosophy from those customarily propounded in dental teaching to date which has concentrated mostly on matters relevant to young and middle-aged persons. Dentists must become proficient in managing clinical entities of prevalence in the elderly. Xerostomia, a frequent, but often neglected symptom can have distressing consequences. Practitioners have a responsibility to detect it, analyse its likely cause or causes and select appropriate therapy. Root caries is re-emerging as a common finding. Its aetiology must be understood in order to institute effective preventive measures and treatment. Dentate elderly persons typically have heavily restored teeth subject to various iatrogenic problems. Some of the restorative work required can be provided exactly as for younger patients. However, optimum care is not necessarily the most elaborate. It is often desirable, when health or financial considerations dictate, to adopt expedients which reduce treatment extent and/or expense. Adhesive materials are extremely useful. The 'sandwich technique' for bonding composite resin to dentine via glass ionomer cement often facilitates the provision of extensive restorations in a minimally invasive fashion. Adhesive procedures can also be applied to treat attrition, mend fatigue fractures, splint teeth deficient in periodontal support, and provide simplified cosmetic treatment for elderly patients.
