การเปรียบเทียบผลการยึดติดทางคลินิกของวัสดุเคลือบหลุมร่องฟันระหว่างการใช้กรดฟอสฟอริกกัดผิวฟันกับสารยึดติดเซลฟ์เอทช์กัดผิวฟัน บนฟันกรามแท้ซี่ที่ 1 ของเด็กอายุ 6-8 ปี / สุวิมล สุเมธิวิทย์ = The comparison of clinical sealant retention between phosphoric acid etching and self-etching adhesive on first permanent molars of 6-8 year-old children / Suwimon Sumethiwit
The purpose of this clinical study was to compare sealant retention between phosphoric acid etching and self-etching adhesive. Ninety-five pairs of contra-lateral first permanent molars from seventy-seven students, age of 6-8 year-old, that met the inclusion criteria were enrolled into an ongoing study. A block randomization was used in which standard sealant method (control group), using phosphoric acid gel, and experimental group, using self-etching adhesive (Adper Prompt, 3M dental product, USA), air thinned before sealant placement (Concise, 3M dental product, USA) and polymerization, were randomly allocated to one of the teeth in each pair within the same oneself jaw. The sealed teeth were checked for retention and caries after six months. There were eighty-eight pairs (one hundred and seventy-six teeth) remaining in the study (92.63%). The retention rate by tooth in experimental group was statistically significant lower than in control group (p-value = .000). There was no carious lesion developed in both two sealed groups during the trial period. It was concluded that Concise White sealant retention on first permanent molars after six months period in self-etching group (Adper Prompt) was less than in phosphoric acid etching group.
