PREVALENCE AND ASSOCIATED FACTORS OF ORAL NON-CANDIDA ALBICANS CANDIDA CARRIAGE IN DENTURE WEARERS IN SANA'A CITY- YEMEN
Objective: The objective of this study was to contrast the prevalence and species of colonization of Non-Candida albicans (NCAC) in the oral cavity of denture wearers and non-denture wearers; also asses associated risk factors of their colonization.
Methods: A total of 208 subjects were studied: 104 denture wearers and 104 non-denture wearers, matched by age, sex, comprised the experimental control groups, respectively. Each subject was instructed to perform oral rinsing using a phosphate-buffered saline solution, which was expectorated processed for the recovery of Candida species on on Sabouraud dextrose agar. Isolates were identified by culturing on chromogenic Candida agar noting species-specific colony characteristics.
Results: There was a significant oral carriage rate of NCAC among denture wearers (5.83% versus 11.1% in controls) with associated risk factor (5.4) (PV<0.001). The most common isolated NCAC were C. Krusi C. tropicalis with significant OR (5.5 4.7 respectively). When co-infections were considered, there was highly significant association of C. albicans + C. krusi oral colonization in cases (OR=4.56, PV<0.001). There was a significant oral carriage rate of NCAC among male denture wearers (36.9%, OR=6.6, PV˂0.001). In addition, there was a significant rate of NCAC colonization with complete denture (rate= 50%, OR=2.4, PV= 0.02). While no significant increase associated with colonization of NCAC with partial, acrylic /or chrome cobalt denture.
Conclusion: Based on the results of this study ability of NCAC were greater in denture wearers than non-denture wearers, also greater risk of NCAC were found with males, older ages, complete denture.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
