Non-invasive management of superficial root caries lesions in disabled and infirm patients.
In disabled and infirm patients with limited, if any, capacity for independent oral self-care, it is difficult to control progression of root caries lesions.


OBJECTIVE
To evaluate the effect of non-restorative cariostatic treatment on progression of active superficial root caries lesions (n = 56).


METHODS
Pilot study.


METHODS
Department of Cariology, Institute of Odontology, Karolinska Institutet, Huddinge.


METHODS
15 physically-dependent patients.


METHODS
The patients were allotted to one of the following groups. Group 1, professional tooth cleaning and application of tap water flavoured with eucalyptus oil; Group 2, professional tooth cleaning and application of Cervitec, (1% chlorhexidine in thymol-containing varnish), Group 3, professional tooth cleaning and application of Cervitec and Fluor Protector (varnish containing 0.1% fluoride). Every three months for 18 months, each subject received the treatment twice within a 10-day interval.


METHODS
The status of the 56 root caries lesions was evaluated every six months using a root caries index based on visual and tactile criteria. The examiners were blind to which treatment group the patients belonged.


RESULTS
In most subjects (14 out of 15), progression of root caries lesions was arrested. No statistically significant differences could be demonstrated between the three treatment groups. However, regardless of treatment regimen, there was a statistically significant difference between the greater number of subjects exhibiting no progression of root caries lesions and those with lesion progression, at 6 (p = 0.022), 12 (p = 0.006) and 18 months (p < 0.001).


CONCLUSIONS
This pilot study suggests that in disabled and infirm patients regular professional tooth cleaning with a fluoride containing paste, with or without supplementary varnishing with chlorhexidine-thymol and/or fluoride can prevent further progression of existing superficial root caries lesions.
