Oral candidiasis is a common opportunistic infection among human immunodeficiency virus (HIV)-infected individuals, with growing concerns about the emergence of non-albicans species with resistance to antifungal agents. This cross-sectional study determined the prevalence of oral Candida species in Thai HIV-infected adults and factors affecting their(More)
In this paper, an adaptive near-far resistant detector using a multiple antennas for acquiring synchronization of an asynchronous DS-CDMA system is presented. The only requirement is the prior knowledge of the user-spreading sequence of interest. Also, there is no need of a training sequence and a training period. Synchronization acquisition of asynchronous(More)
AIM Oral candidiasis is among the most common AIDS-associated opportunistic infections. Adolescents remain at the highest risk of HIV infection and could suffer from oral candidiasis. However, information on oral Candida carriage in this population is limited. This study aims to evaluate the prevalence of oral Candida in Thai adolescents. METHODS Oral(More)
INTRODUCTION Dental caries remains one of the most common chronic infectious diseases throughout the world. The formation of dental plaque is one of the caries risk factors. As a consequence, the removal of plaque may reduce the incidence of caries development. We identified an autolysin produced by Streptococcus mutans named auto-mutanolysin (Aml). Aml(More)
OBJECTIVES To compare the effects of 25% and 35% hydrogen peroxide in-office bleaching systems on surface roughness and streptococcal biofilm formation on human enamel. METHODS Enamel specimens (3mm×3mm×2mm, n=162) from human permanent teeth were randomly divided into 3 treatment groups (n=54 each): (1) control, (2) bleached with 25% hydrogen peroxide(More)
OBJECTIVES To investigate the remineralizing effect of 38% silver diamine fluoride (SDF) application on enamel artificial caries in adjunct to 1000ppm fluoride toothpaste compared with fluoride toothpaste alone by analyzing the mineral density, depth of remineralization, and remineralization percentage of the lesions. METHODS Eighteen artificial caries(More)
OBJECTIVE To compare the effectiveness of a motionless ultrasonic toothbrush to a manual toothbrush in reducing dental plaque, gingival inflammation, and mutans streptococci in patients with fixed orthodontic appliances. MATERIALS AND METHODS Twenty-five orthodontic patients were recruited to this crossover study. The patients were randomized into two(More)
OBJECTIVE To compare the effect of simulated bleaching with a 10% carbamide peroxide (CP) or a 40% hydrogen peroxide (HP) system on surface roughness of resin composite and resin-modified glass ionomer cement (RMGI) and streptococcal biofilm formation on these surfaces. METHODS AND MATERIALS Specimens of nanofilled resin composite and RMGI (n=108 each)(More)
