80 subjects completed a 3month, double blind clinical study which examine the effects of a 3.5% tetrasodium pyrophosphate/ 0.5% hydroxyapatite on the prevention of calculus formation and gingivitis. Control dentifrice had the same formulation with experimental dentifrice exept it did not contain pyrophosphate/hydroxyapatite, The subjects were divided by experimental and control group and received an oral prophylaxis on six lower anterior teeth. After an oral prophylaxis, experimental and control dentifrices were given to subjects according to assigned groups and assigned to use these dentifrices for the next 3 months. Calculus index was checked on 6 lower anterior teeth surfaces and Gingival Index was checked on all gingiva except 6 lower anterior teeth. Calculus index and Gingival index were scored 3 times: before an oral prophylaxis, after 4 and 12 weeks of use of each dentifrice, Modified Volpe-Manhold calculus index and Gingival index of Lo¨e & Silness were used to score each index. The obtained results were as follows; 1. 3.5% tetrasodium pyrophosphate/ 0.5% hydroxyapatite dentifrice was shown to provide a statistically significant reduction of gingivitis after 12 weeks(p<0.05). 2. 3.5% tetrasodium pyrophosphate/ 0.5% hydroxyapatite dentifrice was shown to provide a statistically significant reduction of calculus formation after 12 weeks(p<0.05).

This double blind clinical study was done to assess the effects of the dentifrice containing 3.0% salt, 0.15% sage oil and 17% hydroxyapatite on gingivits and dentin hypersensitivity. 156 subjects were 20-25 year old females and divided into experimental and control group. Gingival index of marginal and papillary gingivae in the bimaxillary anterior teeth and dentin hypersensitiviy index were examined 3 times : baseline, after 1 and 5 months, The gingival index's scoring criteria is the same of L e and Silness' gingival index and dental hypersensitivity was scored by 4 grade which is were severe(1) to normal(4). The obtained results were as follows: 1. The dentifrice containing 3.0% salt, 0.15% sage oil and 17% hydroxyapatite was shown to provide significant reduction of gingivitis after 5 months(p<0.05). 2. The dentifrice containing 3.0% salt, 0.15% sage oil and 17% hydroxyapatite was shown to provide significant reduction of dentin hypersensitiviy 1 month(p<0.05).

30 adult male and female subjects completed 4-week, double-blind clinical study comparing the effect on gingivitis of the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide. Subjects were divided by two balanced groups according to baseline gingivitis scores. Gingivitis index was scored by Lo¨e-Silness' Gingival index. Microhardness of tooth enamel of the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide and the dentifrice containing 0.38% sodium monofluorophosphate, 0.11% sodium fluoride, 0.5% hydroxyapatite, and 3.4% tetrasodium pyrophosphate was measured by microhardness tester(Shimadzu corporation Model, HMV-2000 No. 33100410, Japan) before and after 20,000 strokes with brushing machine, Brightness of tooth enamel of the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide and the dentifrice containing 0,38% sodium monofluorophosphate, 0.11% sodium fluoride, 0.5% hydroxyapatite, and 3.4% tetrasodium pyrophosphate was measured by colorimeter before and after 200 strokes with brushing machine. The obtained results were as follows: 1. The dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide was shown to provide a statistically significant reduction in gingivitis than the control dentifrice after 4 weeks(P <0.05). 2, There was no statistical significant change in the microhardness between the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide and the control dentifrice(P≥0.05). 3. There was no statistical significance of the microhardness changes between the dentifrice containing 0.38% sodium monofluorophosphate, 0.11% sodium fluoride, 0.5% hydroxyapatite, and 3.4% tetrasodium pyrophosphate and the control dentifrice(P≥0.05). 4. There was statistical significance of the brightness changes between the dentifrice containing 0.76% sodium monofluorophosphate and 3.0% carbamide peroxide and the control dentifrice(P<0.05). 5. There was statistical significance of the brightness changes between the dentifrice containing 0.38% sodium monofluorophosphate, 0.11% sodium fluoride, 0.5% hydroxyapatite, and 3.4% tetrasodium pyrophosphate and the control dentifrice(P<0.05).

치면세균막관리는 치주병과 치아우식증을 예방하는데 필수적이다. 이러한 치면세균막관리는 자가관리와 전문가관리로 구분할 수 있는데, 이 두가지줄 병행하였을 때 특히 건강한 치주를 유지하는데 도움을 준다. 자가관리는 1회성 교육으로는 불충분하며 체계적인 반복교육이 필요하다. 전문가관리는 대상자의 구강상태에 따라 일정한 주기로 계속 시행되어야 하며 3~6 개월 주기가 바람직하다. 반복교육과 계속관리과정으로 진행되는 자가 및 전문가 치면세균막 관리 중에 대상자의 구강병 위험요소에 따라 불소도포와 치면열구 전색 등이 제공될 수 있다.
