本發明關於具備清潔口中軟組織表面之清潔器的口部照顧器具。
依據美國牙醫師協會(American Dental Association)，健康人類之壞口氣(bad breath)的主要來源是沈積在舌頭上的微生物，在舌頭上有一藏匿造成壞口氣之有機體和碎屑的細菌覆蓋層。舌頭對微生物的生長來說是個天堂，因為舌頭表面的乳突狀本質創造出一提供極大表面積的獨特生態場所，有助於口中細菌累積。定居在舌頭上的厭氧植物群和細菌對於一般被稱為口臭之慢性壞口氣的生成扮演著重要角色。整體而言，細菌產生揮發性硫化合物(VSC)。如果累積了足夠的硫化合物，結果即是造成壞口氣或口腔異味。
雖說在過去已採用有刃刮舌器，但其在有效性及/或安全性方面有不足之處。此外，儘管藉由盡任何可能清潔舌頭會得到好處，有一些使用者因為此等刮刀在舌頭表面上缺乏舒適性所以避免使用此等刮刀。
因此，需要一種具備舌頭清潔器之口部照顧器具，其有效地去除舌頭細菌和其他碎屑且同時維持使用者舒適性。
本發明關於一種具備組織清潔器之口部照顧器具，其對位在口腔組織表面上的細菌和微小碎屑提供改良的清潔效果和有效的去除效果。
在本發明之一觀點中，該組織清潔器包含用來清潔口中軟組織表面、特別是用來清潔舌頭之乳突之間的複數個凸塊。在本發明之另一較佳觀點中，該組織清潔器包含複數個圓錐狀凸塊。
在本發明之另一觀點中，該組織清潔器由一彈性體材料構成。在一較佳實施例中，該組織清潔器被成型為一安裝在該口部照顧器具之頭部上的彈性體墊以提升清潔效果、便於製造、且讓使用者舒適。
在本發明之另一觀點中，該組織清潔器包含至少一從沿著該器具之頭部延伸之一材料底座突起的突出部。在一實施例中，複數個突出部沿該頭部呈一相互間隔關係沿一被形成為固定於該頭部之一長形條帶的墊延伸。在一構造中，該底座覆蓋一大致剛性頭部結構。另一選擇，該底座係一體成形為該頭部的一部分藉以形成一可撓頭部。
在本發明之另一觀點中，該軟組織清潔器包含至少一長形脊狀部與複數個凸塊或其他具有一非長形結構之不連續突出部的一種組合。因此，舌頭及口中其他軟組織獲益於兩類清潔器突出部得到清潔，從而有一增強清潔效果。
在本發明之另一觀點中，該軟組織清潔器包含硬和軟突出部之一組合用以清潔舌頭及口中其他軟組織。在一構造中，該清潔器包含複數個軟凸塊及至少一硬材料長形脊狀部。依此方式，可在一個器具中獲得軟和硬清潔器的合併利益。
在本發明之另一觀點中，該軟組織清潔器包含至少一具備要被移過舌頭或其他組織之一刮刷邊緣的突出部。該邊緣係由具有不同傾角的傾斜表面構成。在一構造中，一較陡峭斜面大致面向握把藉以在該頭部被拖出嘴巴時提供一更具侵略性的刮刷作用。較淺表面使得該突出部比較不會將舌頭生物薄膜更推回喉嚨深處。
在本發明之另一觀點中，該口部照顧器具包含一用來使該組織清潔器易於模塑在該頭部的承座。在一較佳構造中，該頭部具有用來在該組織清潔器模塑過程中錨定該頭部的一或多個突起。該頭部亦可包含一盆狀區以更進一步界定該模塑組織清潔器的輪廓。
在本發明之另一觀點中，一口部照顧器具包含一具有用來使在使用該工具後兩小時測得的口腔揮發性硫化合物比一基準值減少35%之構件的組織清潔器。
在本發明之另一觀點中，一口部照顧器具具備牙齒清潔元件及一組織清潔器以徹底清潔牙齒、牙齦、舌頭及臉頰和嘴唇的口腔表面。在一較佳構造中，該等牙齒清潔元件和該組織清潔器被支撐在一支撐頭部之相反側上。
在本發明之另一觀點中，一包含牙齒清潔元件和一組織清潔器之口部照顧器具以該等牙齒清潔元件當中至少一元件與該組織清潔器構成一元構件(unitary member)。
藉由參照以下考慮到隨附圖式之詳細說明，將可得到對於本發明及其優點之更徹底理解，圖式中以相同參考數字代表相似特徵。
在以下說明中，就一牙刷說明本發明。舉例來說，牙刷100示於圖1作為一實施例，且牙刷500示於圖8作為一替代實施例。然本發明亦可被用在其他口部照顧器具，包括單純的組織清潔器具。此外，應理解到可運用其他實施例且可就結構和功能予以修改而不脫離本發明的範圍。
如圖1－7所示，一呈牙刷100之樣式的口部照顧器具包含一握把103及一頭部105，該頭部可被用來清潔牙齒和口中軟組織譬如舌頭、臉頰內表面、嘴唇或牙齦。握把103係用來讓使用者輕易抓握並操縱該牙刷，且可被成型為許多不同的形狀和構造。雖然該頭部通常是相對於握把之頸部加寬，其在一些構造中可單純的是握把之一連續延長部或窄化部。在較佳構造中，頭部105具有一支撐牙刷清潔元件107之第一面106(圖5和6)及一支撐一組織清潔器300的第二面108(圖2和3)。第一和第二面106、108最好是在頭部105的相反側上。然組織清潔器300亦可為安裝在他處，譬如握把103之近端104。組織清潔器300或其局部亦可為位在頭部105之外周側壁表面101上或是比圖中所示更往握把103之近端104延伸。
組織清潔器300之彈性體材料可為適用於口腔衛生保健裝置之任何生物相容性彈性材料。為提供最佳舒適性以及清潔功效，該彈性體材料最好具有在A8至A35蕭氏硬度範圍內的硬度特質。舉例來說，一較佳彈性體材料為GLS Corporation生產的苯乙烯－乙烯/丁烯－苯乙烯區塊共聚物(SEBS)。然亦可使用來自其他製造商的SEBS材料或是在所述硬度範圍之內或以外的其他材料。
組織清潔器300較佳被構形為具備複數個組織接合元件303(圖1－4)，此等元件在較佳構造中被成型為凸塊。下文將提到之替代凸塊構造502亦例示於圖8－12之替代構造中。在本說明書中，〝凸塊(nub)〞整體而言係包含一從一基面立起的柱狀突起部(突起部之橫截面形狀不受限)。廣泛地說，在較佳構造中，該凸塊之高度大於凸塊之底座的寬度(以最長方向測量)。然凸塊亦可包含寬度和高度大約相同或者高度略小於底座寬度的突出部。此外，在一些情況中(例如凸塊漸縮到一末梢或是包含一窄化到一較小突出部的底座部分的情況)，底座寬度得為實質大於高度。
此等組織接合元件303被設計為使人的壞口氣主要來源顯著減少並改善衛生。凸塊303能從舌頭及口中其他軟組織表面去除微植物群和其他碎屑。特定言之，舌頭易於滋生細菌覆蓋層，已知此等層藏匿造成壞口氣的有機體和碎屑。此微植物群可在舌頭之上表面大部分上之乳突間凹處以及沿著口中其他軟組織表面找到。舉例來說，在彈性體組織清潔器300之凸塊303接合於一舌頭表面或被以其他方式抵住舌頭表面拉動時，其在向下深入舌頭之相鄰乳突之凹處內的同時提供與軟組織的和緩接合。組織清潔器300之彈性體構造亦使基面301能夠順應口腔組織表面譬如使用者之舌頭、臉頰、嘴唇、及牙齦的自然輪廓。此外，柔軟凸塊303能夠依需要撓曲以沿其移動路程橫越並清潔口中軟組織表面。
如圖2和4所示，在組織清潔器300之一較佳排列中，凸塊303最好是圓錐狀的。在本說明書中，〝圓錐狀(conically shaped)〞或〝圓錐形(conical)〞包含真圓錐體、截頭圓錐狀元件、以及漸縮到一窄端且因而類似於一圓錐體的其他形狀，其錐度是否均勻連續或是否具有圓邊橫截面與此無關。參照圖4，每一圓錐狀組織接合元件303之底座部分305大於對應末梢部分307。在此圓錐狀構造中，底座部分305有一較寬大橫截面區域以提供忍受組織清潔器300沿著舌頭表面或其他軟組織表面側向移動的有效剪切強度。末梢部分307之較小寬度或直徑連同圓錐狀凸塊303之長度讓此等凸塊能夠掃入舌頭及其他表面的凹處內以從軟組織表面清除微生物沈積物及其他碎屑。在較佳構造中，凸塊303能夠在使用中受側向壓力施加時自其相應鉛直軸線撓曲和彎曲。此撓曲作用增強對軟組織表面的舒適性和清潔效果。在一較佳構造中，凸塊之底座的厚度或寬度是0.64 mm，且較佳是在約0.51 mm至約2.00 mm的範圍內。凸塊末梢307是0.127 mm且較佳在約0.10 mm至約0.75 mm的範圍內以獲得穿入使用者舌頭之乳突凹處之間的最佳效果。凸塊303從基面301量到末梢307的長度或高度較佳為0.91 mm且較佳在約0.5 mm至約2.5 mm的範圍內，且最好在0.75 mm至1.5 mm的範圍內。然亦可採用在上列範圍以外之其他大小和形狀的凸塊。
另一選擇，組織清潔元件303可具有其他形狀。舉例來說，組織清潔器可具有格柵形式，譬如共同待審之美國專利申請案序號10/601,106案所揭示，該申請案以引用的方式併入本文中。
在一較佳構造中，凸塊303被以一高密度圖案安置在組
織清潔器300之基面301上。每一凸塊303與相鄰凸塊303之間的間距較佳在約0.5 mm至約3 mm的範圍內；此間距更佳在0.7 mm至2.5 mm的範圍內，且最佳在1 mm至2 mm的範圍內。然其他間距範圍亦屬可行。基面301上之凸塊303的表面密度較佳為每平方英吋約100個至約600個凸塊。在組織清潔器之一更佳構造中，表面密度可為每平方英吋200至500個凸塊，且最佳是每平方英吋300至450個凸塊。在一較佳實例中，組織清潔器300包含每平方英吋表面積約400個凸塊。該表面密度特徵連同凸塊303之高度使該組織清潔器能以改良的舒適度對軟組織表面提供更強清潔效果。然其他表面密度亦屬可行。
如圖3所示，凸塊303最好被安置成依一大致平行於縱向軸線a－a之方向的縱列。此外，凸塊303被安置成在一平行於基面301且大致垂直於縱向軸線a－a之軸線上的橫列R1、R2。在一較佳構造中，相鄰凸塊303係以一交錯排列提供在基面301上。舉例來說，相鄰的凸塊橫列R1和R2具有不是相互位於正後方的凸塊303。一第一凸塊被稱為是位於第二凸塊〝正後方〞的條件是其被定位在該第二凸塊以一縱向方向延伸之側向邊界內。此組態因有助於去除微植物群和其他碎屑、特別是從舌頭之相鄰乳突之凹處去除微植物群和其他碎屑故能改善軟組織表面清潔效果。然凸塊亦可為被隨機地或依據眾多不同圖案排列。
舌頭清潔器300較佳係由模塑於頭部105的方式形成，但亦可採用其他製造方法。參照圖1和4，組織清潔器300最好被模塑在頭部105之面108的一盆狀區或一收納腔111內。收納腔111有一下部基面113及一從下部基面113伸出的外周側壁115。在一安裝排列中，組織清潔器300之凸塊303在組織清潔器300之基面齊平於頭部表面114或相對於該表面為凹下的狀態下外露供人使用。然其他取向亦屬可行。又，組織清潔器基面301可為埋入頭部105或被具備讓凸塊303從適當開口突出的另一層覆蓋。
如圖1和4所示，面108較佳亦包含位在盆狀區111內的一或多個樁構件117a－c。樁構件117構成抵住對向模具的錨定點以防該頭部在射出成型作業的壓力下移動。因此，組織清潔器300較佳包含一或多個讓樁構件117a－c之頂部外露的互補孔311a－c。雖然圖中所示之樁沿著頭部的中心線(例如縱向軸線a－a)對齊，此等樁可具有許多不同位置。此外，樁和盆狀區最好都是包含在頭部105內，但任一者皆可在沒有另一者的情況下使用。
另一選擇，盆狀區111和樁構件117a－c可被用來定位並固持一事先模塑的組織清潔器，但這些構造並非必然使用此一事先模塑的組織清潔器。
樁構件117a－c可採取多樣形狀和長度。繼續參照圖1和4，頭部105包含從盆狀區111之下部基面113延伸到外周側壁115之高度的樁構件117a－c。樁構件117a－c被造型成圓柱體形式，但其他形狀和長度的樁構件117a－c亦屬可行。雖然模造程序會使組織清潔器較佳地結合於頭部，該組織清潔器可為預製的且是藉由黏著劑或其他已知構件附裝。
如圖1－4所示，組織清潔器300最好被成型為一由柔軟彈性體材料構成的墊以求舒適地清潔且有效地去除沈積在舌頭表面上、口中其他軟組織上及甚至沿嘴唇沈積的細菌和碎屑。組織清潔器300亦提供有效的按摩效果、刺激效果以及從舌頭、臉頰、牙齦或嘴唇之表面去除細菌、碎屑和上皮細胞的效果。
在較佳構造(圖1－6)中，組織清潔器300可在使用者刷牙的同時摩擦臉頰內側表面或嘴唇以及舌頭側面，從而提供一期望的按摩效果、刺激效果以及清潔口中各個軟組織表面的效果。舉例來說，在刷洗正面牙齒表面期間，組織清潔器300被安置在頭部105的外面108上而自然地摩擦臉頰的口腔表面。因此，無須額外清潔步驟即得到增強的清潔效果。此外，有一些使用者可能感覺到臉頰表面上有一造成正向使用者反應的刺激性刺痛感，甚至會樂在該組織清潔器沿口中軟組織表面造成的舒適感受。組織清潔器300亦可視需要附帶地摩擦臉頰、舌頭等以在刷牙之時可能發生的接觸之外做更進一步的清潔。
參照圖5和6，頭部105之牙齒清潔元件107可包含能被用來擦拭、清潔和按摩使用者之牙齒和牙齦的多樣牙齒清潔元件。任何適用形式的牙齒清潔元件皆可使用。本說明書所述〝牙齒清潔元件(tooth cleaning elements)〞係就廣義來說，其指具有任何期望形狀的單絲刷毛或是彈性體指狀物或壁狀物。在圖5範例實例中，牙齒清潔元件107包含位在頭部105之一末梢121的遠端牙齒清潔元件203a－b；外周牙齒清潔元件205a－1；沿縱向軸線a－a配置的縱向牙齒清潔元件207a－c；拱形牙齒清潔元件209a－d和211a－b；及近端清潔元件213a、b。牙齒清潔元件205、207、211和213較佳係以刷毛束提供，而牙齒清潔元件209較佳被成型為彈性體壁。然亦可採用其他形式和類型的牙齒清潔元件。
圖7繪出一牙刷之頭部400之替代排列的剖面圖。頭部400的構造與頭部105相似，差別在於牙齒清潔元件209a－d係與組織清潔器300一體成型。為完成此替代構造，頭部400具有適當大小的埠口或開口401以容許彈性體材料在一射出成型製程中流過該頭部。在此構造中，牙齒清潔元件209a－d和組織清潔器300係以相同彈性體材料構成。因此，頭部400可包含與組織清潔器300成型為一元構件之至少一彈性體牙齒清潔元件。
在圖8中，牙刷500包含從頭部506之一背側504突出的複數個凸塊或其他突出部502，其當作口中軟組織之一清潔器508。牙齒清潔元件516較佳從頭部506之一前側505伸出。突出部502較佳為沿著至少一呈固定於頭部506之條帶510之樣式的窄底座或墊依序排列。在圖示實例中，複數個大致平行條帶510a、510b、510c、510d被固定成一背對握把的大致凹形形狀。在此一構造中，該等條帶沿著頭部506之背側504及每一側壁511延伸，但沿側壁延伸是並非必要的。得含有任何數量的條帶。此等條帶可在頭部上定義幾乎任何形狀或取向。舉例來說，條帶510可具有在2004年11月17日申請之發明名稱為〝Oral Care Implement〞的共同待審美國專利申請序號10/989,267案(代理人文件編號006427.00131)中揭示用於脊狀部之任何形狀，該案之內容以引用的方式併入本文中。在例示構造中，條帶510由一軸向莖狀部512互連，該莖狀部伸入握把內且構成使用者抓持部的一部分。此外，此種握把延伸部或甚至莖狀部理所當然並非必要的。
在一構造中，每一突出部502大致為柱狀且被形成為有一約1.1 mm之寬度W及一約1.7 mm之高度H(圖9)。該等突出部沿著條帶510相互間以一約1.0 mm之距離隔開。然這些高度、寬度及間隔尺寸可有大幅變動。在圖示實施例中，突出部502每一者包含一從底座510突出的周壁513，及一相對於頭部506之側表面504成一約50度之角度的傾斜遠端表面514。斜端面514沿周壁513之一部分定義一窄頂緣516，其有利於清潔舌頭和其他軟組織。雖然圖中所示端面514是以相同方向傾斜，其亦可為以不同方向傾斜。
在一替代構造(圖13)中，頭部506更具備至少一長形脊狀部525。利用此排列，會為使用者提供一清潔器，其藉由將不連續的突出部502和脊狀部525移過舌頭或其他組織而獲得一有利雙重清潔效果。在例示實例中，脊狀部525是一沿著刷頭遠端527之外緣大致往外突出的長條曲線形突出部。然其他配置、位置和形狀亦屬可行。亦可能提供附帶脊狀部。在一較佳構造中，脊狀部525被模製成與頭部為一體且由一較硬塑膠譬如聚丙烯構成。然該脊狀部亦可為獨立於頭部形成且/或由其他適合用於口部照顧器具的材料組成。
在一構造中，脊狀部525如前所述是由一較硬材料(譬如聚丙烯)構成，而突出部502是由一較軟材料(譬如一熱塑性彈性體)構成。此種雙重材料的使用能夠獲得兩種材料的好處。清潔器包含脊狀部525中之較硬刮刀以及在戳入舌頭或其他組織時會撓曲及翻轉之較軟不連續突出部的紮實接合。
如圖13和14所示，脊狀部525係由一對反向側壁533、534定義，此二側壁會合形成一刮刷邊緣535。雖然此構造中之邊緣535比較窄，其亦可為實質加寬的。在一實施例中，側壁533、534被形成為相對於頭部506之側面504呈不同斜度，但其亦可為具有相同斜度。在一較佳構造中，側壁533被形成為其斜度比側壁534更陡峭以定義一在頭部被使用者拉過舌頭時更具侵略性的刮刷作用。側壁534大致背對於握把之較淺斜度使得脊狀部在被朝向咽喉推回時比較不易於將舌上生物薄膜推回咽喉更深處。在一較佳實施例中，側壁533被定向為相對於側面504成一62度的角α，而側壁534被定向為成一43度的角β。亦可將其他角度用於此二角。
在另一替代構造(圖10)中，每一突出部502a具備一擁有二個斜端面部分515a、517a及一頂緣516a的端面514a。一如脊狀部525，大致面向握把之端面部分515a較佳相對於側面504a以一比端面部分517a更為陡峭的角度傾斜，但亦可採用其他排列、包含此二端面部分具有相同傾角的配置。作為一實例，端面部分515a被定向為相對於側面504a成一62度之角α，且端面部分517a被定向為成一43度之角β。端面部分515a之較陡峭角度提供一在頭部被拖出嘴巴時更具侵略性的刮刷作用。端面517a之較淺角度使突出部比較不易於將舌上生物薄膜推回咽喉更深處。
當然，亦可採用其他突出部。舉例來說，每一突出部可包含一不傾斜遠端或一漸縮成一尖頭的末端。突出部可具有除圖8所示圓柱形狀以外之多樣形狀。舉例來說，突出部可具有圓錐形狀、不規則橫截面、或是對背側504傾斜。此外，突出部亦可為脊狀造型以完全或部分地沿條帶510之長度延伸。
在一較佳構造中，突出部502及條帶510被形成為模製或以其他方式固定於頭部506的單件式構件。突出部和條帶較佳被形成為一彈性熱塑彈性體譬如GLS Corporation生產之苯乙烯－乙烯/丁烯－苯乙烯嵌塊共聚物(SEBS)的單件式構件，然亦可由其他彈性材料、硬材料、或諸如在2004年12月15日申請之發明名稱為〝Oral Care Implement〞的共同待審美國專利申請序號11/011,605案(代理人文件編號006427.00132)中揭示之材料組合構成，該申請案之內容以引用的方式併入本文中。突出部和條帶亦可為用與頭部506相同的物質(譬如聚丙烯)構成，但具有不同顏色或類似條件以界定其為一異於頭部的不同材料且藉此創造至少一引人注目的牙刷。
在一構造中，條帶510被模製為蓋在頭部506之一大致平坦表面504上(圖9)。然亦可在側面504內形成渠道507來收納條帶510，使得側面504與具有突出部502之條帶510的外表面512大致共面(圖11)。此外，彈性材料之條帶可被形成為頭部構造之一體部分(圖12)。更明確地說，在此替代構造中，頭部包含藉由一彈性第二構件522接合在一起的複數個第一構件520，該第二構件當作一活鉸鏈以許可該等第一構件在牙刷使用期間相互相對移動。該第二構件亦形成軟組織清潔器506之具備突出部502的底座510c。此外，如有關牙刷400之說明，突出部502或502a得與從頭部以一反方向伸出之彈性牙齒清潔元件一體成形為單件式構件。
由於可就上述方法、組合物及結構物做出多種未脫離本發明範圍的變化，吾人希望本說明書所含之所有內容、包含以上敘述的所有機構及/或互動模式應當被解釋為只是範例且不應以任何方式約束所附申請專利範圍項的範圍。
以下提出代表本發明之改良操作的實例。這些實例不應解釋為限制本發明的範圍。
實例1
一牙刷的性能本質可藉由習知的口腔異味評估方法測量。吾人進行評估一具備有圓錐狀凸塊之一彈性體組織清潔器的牙刷、譬如前述牙刷100之較佳構造之性能的研究。在本研究中有人類實驗受測者。在測試之前有一段大約7天的洗淨或均一化時間，在此期間實驗受測者使用一氟化物牙膏(參見表一)每天刷牙兩次。在該洗淨期之後，要求這些實驗受測者在口腔測試之前戒除任何口腔保健工作(刷牙、漱口、及使用牙線)以及飲食。從每位實驗受測者取得一基準揮發性硫化合物(VSC)樣本。在過夜氣味控制的研究中，實驗受測者以具備前述組織清潔器300之牙刷100用一氟化物牙膏(參見表一)刷牙一分鐘。隨後這些受測者以該牙刷之組織接合元件清潔舌頭表面十秒。讓這些實驗受測者睡過一夜後回來進行後期處理。在距離前一天清潔工作十小時的時間點取得VSC樣本。在此範例實例中，由使用後十小時之基準測得之使用該牙刷者的口腔VSC比起只有刷牙者減小大約60%。此等VSC讀數係由氣相色層分析法獲得。
實例2
在前述牙刷100之另一研究中，在測試之前有一段大約7天的洗淨或均一化時間，在此期間實驗受測者使用一氟化物牙膏(參見表一)每天刷牙兩次。要求這些實驗受測者在口腔測試之前戒除任何口腔保健工作(刷牙、漱口、及使用牙線)以及飲食。在該洗淨期之後，該等實驗受測者藉由以一無菌棉花拭子擦過舌頭背面之一側的方式提供一基準舌頭細菌樣本。實驗受測者以具備前述組織清潔器之牙刷用一氟化物牙膏(參見表一)刷牙一分鐘。隨後這些受測者以一較佳構造之牙刷100組織接合元件300清潔舌頭表面十秒。在清潔舌頭表面之後兩小時，用一棉花拭子從舌頭背面之一側取得一舌頭細菌樣本。在本範例實例中，組織接合元件的使用比起只有刷牙會控制更多導致氣味的舌頭細菌。使用組織清潔器300者在該清潔器用於舌頭上兩小時後呈現超過0.8 Log菌落形成單位/毫升的舌頭細菌對數減少量。
實例3
在前述牙刷之另一研究中，採用一MTT化驗法來檢驗在使用具備前述組織清潔器的牙刷之前和之後從口腔採集到之上皮細胞的存活性。該MTT化驗法係以四唑鹽MTT〔3－(4,5－二甲基噻唑－2－基)－2,5－二苯基－四唑溴化物＋＋＋〕在活著、有新陳代謝作用之細胞內的酵素還原作用為基礎。該反應係在試管內就地進行，且利用一多孔平板讀取器以比色方式測量反應產物－可溶於二甲亞碸內的紫色甲。有利的是，該MTT化驗法為大規模化學敏感性實驗提供高精確度、使用便利性、以及適用性。
在經過7天洗淨期之後，實驗受測者在尚未進行飲食或口腔保健工作之前到一實驗場所報到。該等實驗受測者以使用9毫升無菌水漱口10秒然後將漱口過的水排入一裝有10×無菌磷酸鹽緩衝鹽水(PBS)溶液之管內的方式提供唾液漱口樣本。該等樣本在進行MTT化驗法之前被冷藏大約30分鐘。實驗受測者在受監督狀態下使用一氟化物牙膏(參見表一)刷牙一分鐘然後用較佳構造之舌頭清潔器300清潔舌頭10秒。在刷牙並清潔舌頭之後大約30分鐘，實驗受測者依前述方式提供漱口樣本。
將前期漱口樣本和後期漱口樣本以大約3000 RPM離心15分鐘。將上澄清液(例如清澈液體)去除且使丸狀物再懸浮於2.5毫升的PBS內。將該等樣本攪拌5秒，然後添加2.5毫升的MTT溶液。隨後讓該等樣本在一被設定為37℃之緩慢搖晃水槽內培養2小時。在此2小時培養期之後，將該等樣本以大約3000 RPM離心15分鐘。將上澄清液吸出並添加3毫升的清潔劑(0.04 N酸性異丙醇)以溶解紫晶體。MTT轉化過程的增加或減少經分光光度量測方式量化。將每一樣本各取200微升添加於96孔平板，以570 nm光測量光學密度並與一負緩衝對照物做比較。在本範例實例中，由一MTT化驗準則判定，於一分鐘刷牙後以10秒使用該組織清潔器會使口腔上皮細胞減少大約72 %。
實例4
在另一研究中，人類實驗受測者經由一HalimeterT M (亦即硫化物計量器)提供基準VSC樣本。HalimeterT M 使用一電化學伏安感測器，該感測器在暴露於VSC譬如硫化物和硫醇氣體時產生一信號且測量硫化氫氣體的十億分之一濃度。該等實驗受測者在受監督狀態下使用具有前述組織清潔器之較佳構造牙刷刷牙一分鐘。然後，實驗受測者使用前述牙刷在舌頭表面上提供六次動作。在刷牙階段之後兩小時從實驗受測者取得後期VSC樣本。在本範例實例中，使用具備組織清潔器之牙刷者在該清潔器用於舌頭上兩小時後測得之口中氣味的VSC比一基準值減少35%。
實例5
於另一研究中，在一段洗淨期之後，人類實驗受測者用無菌水漱口以為MTT化驗法之活上皮細胞分析提供一基準樣本。該等實驗受測者在受監督狀態下使用具有前述組織清潔器之較佳構造牙刷刷牙一分鐘。然後，實驗受測者使用前述組織清潔器在舌頭表面上提供六次動作。該等實驗受測者提供一分析用後期漱口樣本。以在實例3所述方式對該等樣本進行測試和分析。在本實例中，由MTT化驗準則判定，使用該牙刷會使口腔上皮細胞比一基準值減少大約92%。
在上述實例中，受測者使用具有表一所列配方之氟化物牙膏刷牙。
