| Study objectives | Root caries is an increasing clinical problem affecting some 80 per cent of dentate elderly and especially those in residential homes and the house-bound. Root caries develops in older adults as the gingival tissues recede to expose the root surface and bacteria accumulate as the gingival margin. The measurement of root caries is difficult due to the high organic content of the root dentine, the proximity of the lesion to the gingival margin and the difficulty in gaining access to the disease in patients who may be frail and elderly or who give only limited co-operation with the treatment. The development of novel anti-microbial treatment regimens, in combination with conventional topical fluoride, may enable the development of new management protocols for the treatment of existing root carious lesions and for the prevention of new lesions. We propose to determine, in a double-blind placebo controlled trial, the effects of a antimicrobial varnish containing chlorhexidine and thymol in conjunction with a remineralising, fluoride-containing varnish on clinical and microbiological parameters of root carious lesions. The control procedure will consist of the fluoride varnish and a placebo varnish in place of the chlorhexidine-thymol varnish. This project may demonstrate a new, non-restorative means of managing root carious lesions in institutionalised and home-bound individuals which would be more readily accepted by the patient and enable the practitioner to manage root caries more cheaply and more efficiently. |
