DIAGNOSIS AND PATHOLOGIC FINDINGS: ORAL CANDIDIASIS
Smear From the infected area, which compromises epithelial cells, creates opportunities for detection of the yeast Pseudomembranous oral candidiasis and angular cheilitis are suspected Second scrape Method is a valuable adjunct in the diagnostic process of erythematous candidiasis and denture stomatitis as these infections consist of fairly homogenous erythematous lesions Salivary culture techniques Culture sensitivity testing Histopathologic exam Chronic plaque- type and nodular candidiasis, cultivation techniques Identify the possible presence of epithelial dysplasia
112
Causative agents: ANGULAR CHEILITIS
candida and staphylococcus aureus
112
Infected fissures of the commissures of the mouth often surrounded by erythema
ANGULAR CHEILITIS
112
Infection is considered a portent of Aids development Advice the patient to do a work up Pseudomembranous candidiasis, erythematous candidiasis, angular cheilitis, and chronic hyperplastic Candidiasis
ORAL CANDIDIASIS ASSOCIATED WITH HIV
112
More than 90% of patients present with AIDS present oral candidiasis during course of HIV infections
ORAL CANDIDIASIS ASSOCIATED WITH HIV
112
MANAGEMENT: ORAL CANDIDIASIS
Antifungal drug Polyenes or azoles Azoles Miconazole for angular cheilitis Topical treatment biostatic effect on S. Aureus and fungistatic effect to candida Systemic azoles for deeply seated primary candidiasis, such as chronic hyperplastic candidiasis, denture stomatitis, and median rhomboid glossitis with a granular appearance and for therapy- resistant infections, mostly related to compliance failure Known to interact with warfarin Development of resistance is particularly Compelling for fluconazole in HIV patients Polyenes Nystatin and amphotericin B Negative effect on the production of ergosterol, which is critical for the candida cell membrane integrity. Polyenes can also affect the adherence of the fungi
112
SYMPTOMS: ANGULAR CHELITIS
Dry skin, red areas at the corner of the lips
112
Predilection: CHRONIC PLAQUE

112
MANAGEMENT AND PROGNOSIS: Denture Stomatitis
Permanent removal of the denture Improved denture hygiene and a recommendation not to use the denture while sleeping If asymptomatic, pt may opt for no treatment Type III denture stomatitis
112
Surface of these lesions tends to be: thickened slough that extends deep into the surrounding tissue
MUCOSAL BURN
112
MANAGEMENT AND PROGNOSIS: Type III denture stomatitis
Surgical excision if necessary to eradicate microorganisms present in the deeper fissures of the granular tissue Continuous treatment with topical antifungal drugs Need to remove because they have deeper fissures
112
MANAGEMENT AND PROGNOSIS: ANGULAR CHEILITIS
Mild steroid ointment for cases of inflammation Prognosis is good if predisposing factors associated with the infection are reduced or eliminated
112
MANAGEMENT AND PROGNOSIS: Persistent chronic plaque- type and nodular candidiasis
Increased risk for malignant transformation compared with leukoplakias not allied with candida Infection Patients with primary candidiasis are also at risk if systemic predisposing factors arise
112
