Clinical Effect of MS Coat and Elmex gel on the Dentin Hypersensitivity following Periodontal Surgery

치주수술 후 지각과민증에 대한 MS Coat와 엘멕스 겔처치의 임상적 효과

Dentinal hypersensitivity is one of the complicated symptom rather than a disease. It has special reaction or pain over uncovered root by heat, mechanical or chemical stimulations, which are normal with healthy teeth, The purpose of this study is to discover rather MS Coat (oxalate-containing pre-polymerized resin suspension) or Elmex gel(amine fluoride+sodium fluoride) is effective on hypersensitivity after periodontal treatment using NRS(Numerica1 Rating Scales), which it is useful for evaluating pain level. This study has been prepared in Dankook Dental Hospital with generally healthy adult who had been suffered from dentinal hypersensitivity after periodontal treatment. Divided in three groups with saline(control group), MS Coat(test 1 group) and Elmex gel(test 2 group). And then, following evaluations were made at the end of 1 minute, 1 week, 1 month and 3 months. 1. The sequence of higher frequency & severeness of hypersensitivity is water within $7^{\circ}C$, air stream & explorer. 2. As time goes on, 1 minute, 1 week, 1 month & 3 months, severeness of hypersensitivity scored lower with water, air stream and explorer. 3. With explorer, the differences among three groups as time had to seen. 4. With air stream, the sensitivity scored lower after 1min with MS Coat, Elmex, and saline sequence. As time goes on the sensitivity was lower with MS Coat and Elmex than saline, but there was no difference between MS Coat and Elmex. 5. With water in $7^{\circ}C$, the sensitivity was much decreasing with MS Coat and Elmex than saline, but there was no difference between MS Coat and Elmex. As the result, MS Coat and Elmex are effective on hypersensitivity caused by periodontal treatment.
