PERBEDAAN KEEFEKTIFAN MENYIKAT GIGI TEKNIK ROLL (MODIFIKASI STILLMAN) DENGAN TEKNIK FONES (SIRKULER) TERHADAP PEMBENTUKAN PLAK BARU Penelitian pada Sekolah Dasar Negeri Percobaan 2 Yogyakarta

Plaque is soft attached deposit on the tooth surface comprising of microorganism that could nuthiply in a cellular matrix. The cause of the caries and periodontal disease mostly occurs due to plaque that couldn't remove completely. The plaque formation has been formed through three stages, the first stage is characterized by acquired pelicle which comprised of mucoprotein and salivary glycoprotein involving aerobic bacteria. Those form extracellular polysaccharides called the newly formed plaques in one to three days. The second is characterized with increased of many gram-negative coccus bacteria and bacillus called proliferation and colonization phase and take about two to four days. The last stage is called the stage of maturation. It occurs four to nine days and characterized with a complex ecology of microorganisms. Cleaning plaque could be processed by physically and chemically. One of the chemically process is using of cleaning solution such as chrolhexidine, while the physical cleaning process is brushing the teeth properly. This study used a cross-sectional study design with the design of quasi-experimental research approach. The subjects of this study were sixth grade students in Percobaan 2 elementary school aged 11-12 years who were divided into 2 groups. Group 1 was instructed to brush their teeth by Roll or modified Stillman technic, while the second group instructed to brush by Fones technic or Circular. The whole subject of the new plaque score was calculated by using the PHP index before and after brushing the teeth. The data were analyzed by using paired sample t-test then continued by using independent sample test trials. The results shows that 0.038 where p <0.05 then HO is rejected, which means that there are significant differences in the two technics. There is an effective technic of cleaning teeth using the Roll and Circular technic.
