Evaluation of an optical instrument for objective assessment of oral mucosal erythema

A clinical trial of light cure acrylic resin for orthodontic use

OBJECTIVE

To ascertain whether or not the less porous surface associated with visible light cure appliances and the absence of free monomer had any measurable affect upon mucosal erythema, and to assess the durability of such appliances in a clinical context.

DESIGN

A prospective randomized trial of visible light cure (Triad VLC) and autopolymerizing (Orthoresin) acrylic resin used as orthodontic base plate materials.

SETTING

University Dental Hospital and School.

SUBJECTS

Fifty subjects from a consecutively enrolled sample of 69 (19 drop outs) for removable appliance therapy (23 VLC, 27 AP).

OUTCOME MEASURES

Erythema meter scores and appliance breakages.

RESULTS

No statistical difference in mucosal erythema between the two materials was found. Fifty-two per cent of VLC appliances broke during a 6-month period, as opposed to 7 per cent of AP appliances.

CONCLUSIONS

VLC appears to have no clinically beneficial effect on the oral mucosa compared with AP. VLC appliances are currently not sufficiently durable to make them a viable alternative to AP appliances.

Efficacy of the cyclodextrin liquid preparation of itraconazole in treatment of denture stomatitis: comparison with itraconazole capsules

This study investigated the efficacy of a cyclodextrin solution of itraconazole in the treatment of Candida-associated denture stomatitis. It was found that the liquid and capsule preparations of itraconazole were equally effective adjuncts in the treatment of this condition. However, the side effect profile indicates that capsules are the preferred formulation.
