The Prevalence of Microorganism in Paediatric Angular Cheilitis Patients

Angular cheilitis presents as infected fissures of the commissures of the mouth, often surrounded by erythema. Angular cheilitis has many different etiologies, such as infection. Colonizing organisms such as β-haemolytic streptococci, Staphylococcus aureus, and Candida albicans can develop into pathogens. The aim of this study was to determine the prevalence of microorganism in paediatric angular cheilitis patients. The research was clinical and laboratory study with 42 paediatric angular cheilitis patients. The research was conducted in Universitas Sumatera Utara Dental Hospital and Universitas Sumatera Utara Hospital in Medan. Demographic data was obtained from medical record. Diagnosis of angular cheilitis was done with clinical examination. Microorganism examination was done in Microbiology Laboratory Universitas Sumatera Utara Hospital, Medan. The results showed Staphylococcus aureus was found in 21 patients (50%), followed by Enterobacter cloacae 5 patients (11.9%), and Staphylococcus warneri 2 patients (4.76%). Meanwhile Klebsiella pneumonia, Streptococcus gordonii, Streptococcus oralis, Bordetellabronchiseptica, Streptococcus pseudoporcinus, Streptococcus agalactiae, Streptococcus salivarius, Gamellamorbilorium, and D. nishinomiyaensis was found in 1 patient. Furthermore, Polymicrobial culture consist of Staphylococcus aureus and Candida tropicalis and D. nishinomiyaensis and Candida tropicalis was also found in 1 patient. This study showed that microorganism have an important role in angular cheilitis with Staphylococcus aureus being the most found microorganism.
