ABSTRACT
Candida species inhabit the oral cavity of all individuals who wear complete denture and whose material is the same as that used in splints. Assess the growth of C. albicans in occlusal and palatal splints used for treatment of TMD so that the potential risks of oral microbiota can be assessed. The growth of Candida spp. was assessed in the saliva of 27 individuals wearing splints for treatment of TMD. They were divided into two groups: G1 (n = 14), individuals wearing occlusal splint; and G2 (n = 13), individuals wearing palatal splint. Saliva samples were collected during placement of the splints (T1) and after 4 months (T2), being stored in PBS (10 mL) after 60-second rinses. It was observed that patients wearing occlusal splints (G1) had an increase of 0.648 CFU/mL (Log 10), with statistically significant differences (P = 0.043) for C. albicans (42.33%), C. glabrata (5.52%), C. krusei (41.72%) and C. tropicalis (10.43%). In the group of patients wearing palatal splints (G2), there was a decrease of 0.101 CFU/mL (Log 10), was observed with (P = 0.964) only the presence of C. albicans. The results suggest that growth of Candida species was greater in patients wearing occlusal splints compared to those wearing palatal ones as the presence of different yeast species was found in the former.
Espécies de Candida habitam a cavidade oral de 60-100% de indivíduos usuários de prótese total, cujo material é o mesmo utilizado em placas miorrelaxante. Avaliar o crescimento de C. albicans. em placas relaxantes musculares oclusais e palatais, usadas para o tratamento de DTM, na intenção de verificar riscos em potencial à microbiota bucal. Avaliou-se o crescimento de Candida spp. na saliva de 27 indivíduos, usuários de placa miorrelaxante, em tratamento para DTM no ICT-UNESP. Os indivíduos foram divididos em dois grupos: G1(n=14) placa com recobrimento oclusal; e G2 (n=13) sem recobrimento. As coletas foram com PBS (10mL), em bochechos por 60seg, na instalação das placas (T1) e após 4 meses (T2). Observou-se que pacientes usuários da placa miorrelaxante com recobrimento oclusal (grupo G1) apresentaram aumento de 0,648 UFC/mL (Log10) com diferença estatisticamente significante (p=0,043) analisando-se 42,33% C. albicans, 5,52% C. glabrata, 41,72% C. krusei e 10,43% C. tropicalis. No grupo de pacientes que utilizaram a placa sem recobrimento (grupo G2), observou-se diminuição de 0,101 UFC/mL (Log10) com (p=0,954) apresentando apenas C. albicans. Os resultados sugerem que os pacientes que fizeram uso de placa miorrelaxante com recobrimento oclusal apresentaram maior crescimento de Candida spp. em relação aos usuários de placa sem recobrimento, verificando-se a presença de diferentes espécies da levedura.
