Thirty children from the Home for needs (Tiruvallur) who fit with inclusion criteria and are willing to participate, shall be enrolled. The children will be introduced and subjected to OHIP-14 questionnaire to assess their oral health related quality of life(OHRQoL) and baseline oral swab will be collected to assess the Candida albicans carriage in the oral cavity. Swab sample will be taken by rolling the sterile cotton swab across the dorsum of the tongue, vestibular sulcus and peak of the palatal vault. Swab sample will be immediately smeared onto the surface of culture plate with Sabouraud’s dextrose agar(100gm)(with chloramphenicol 10%). The collected swabs will be transported in cold chain maintained at 4 degree C within 2hours from the time of collection. Plates will be aerobically incubated at 37° centigrade for 48 to 72 hours. Number of Candida colonies will be determined by counting Colony Forming Units on Sabouraud’s dextrose agar plates. Preliminary identification of Candida will be carried out after the growth of characteristic creamy convex yeast colonies on SDA. All the microbiological analysis will be done at Standard Healthcare Multi-Speciality clinic and Diagnostic Centre  at Pallikaranai, Chennai. This will be followed by dental treatment such as restoration and extraction. Oral hygiene kit will be provided commonly to all the participants to maintain homogeneity in oral care. Daily reminders about oral hygiene will be given through phone calls to all participants. Four weeks after finishing the dental treatment, another oral swab sample will be  collected from the patients according to the criteria described previously. Post-treatment OHIP-14 questionnaire will be administered finally.
