Effect of a benzoic acid-detergent germicide on denture-borne Candida albicans.

Benzoic acid combined with a detergent was used to safely and effectively decontaminate dentures colonized with Candida albicans. Surface decontamination was accomplished by soaking the dentures in the germicide solution for a period of 6 hours to overnight. Decontamination may occur in as little as 10 minutes when soaking is combined with ultrasonic enhancement.

Nonrestricted multiple-choice examination items.

Multiple-choice items are frequently used in objective examinations. The format chosen should conform to the nature of the instruction. Knowledge about cumulative information, such as lists of attributes, can be tested efficiently by means of multiple-choice items that include a variable number of correct answers. In contrast to conventional, single-answer questions, nonrestricted multiple-choice items are capable of including more facts and fewer incorrect responses. In addition, the nonrestricted format is not burdened with the repetitious pattern of one correct answer coupled with several incorrect responses, a cue that may promote successful guessing. Item analyses can be performed on examinations that include both conventional and nonrestricted items. The reliability of one examination constructed totally with nonrestricted items was analyzed by means of the Kuder-Richardson Formula No. 20. The value 0.72 proved this examination to be both discriminating and consistent.

Effects of Candida treatment regimens on the physical properties of denture resins.

Denture stomatitis affects approximately 65% of all denture wearers and Candida albicans has been established as a primary etiologic agent. Treatment of the condition necessitates removal of the organism from denture resins by soaking in cleansing/disinfecting solutions. These solutions can have deleterious effects on denture resins. Physical properties (flexure strength and surface hardness) of heat- and light-polymerized denture resins (Lucitone Pink and Triad) were evaluated after candidal colonization and candidal treatment regimens. Light-activated resins may be the materials of choice for patients prone to denture stomatitis, as they have demonstrated less overall degradation from candidal treatment modalities.
