技术领域
本发明涉及一种带有清洁器的口腔护理器具,用于清洁嘴里的软组织表面。
背景技术
根据美国牙科协会的统计,健康人群的不良气味的主要来源是舌头上的微生物引起的沉积,细菌覆层在此处驻留有机物和碎屑从而产生不良的气味。舌头是微生物生长的天堂,这是因为舌头表面舌乳头的性质创造了独特的生态位置,其提供非常大的表面面积,促进口腔细菌的积聚。残留在舌头上的厌氧细菌群和细菌在慢性难闻气味一般称为口臭的发展中扮演重要的角色。一般而言,细菌产生挥发性硫化物(VSC)。如果有足够多硫化物的聚积,就会导致不良气味或口腔恶臭。
虽然刀片的舌头刮擦器过去得到使用,但这些刮擦器不能充分地满足有关有效性和/或安全性的需要。而且,尽管能获得清洁舌头的能力,但一些使用者避免使用此刀片,因为在舌头表面缺乏舒适性。
因此,需要一种带舌头清洁器的口腔护理器具,其在保持使用者舒适的同时,提供了舌头细菌和其它碎屑的有效移除。
发明内容
本发明涉及一种带有组织清洁器的口腔护理器具,其提供了改进的清洁并有效移除沉积于口腔组织表面上的细菌和细微碎屑。
在本发明的一个方面,组织清洁器包括用于清洁嘴里软组织表面并特别用于清洁舌头的舌乳头之间的多个凸起。在本发明进一步优选的方面,组织清洁器包括多个成圆锥形成形的凸起。
在本发明的另一个方面,组织清洁器由弹性体材料构造成。在一个优选的实施例中,组织清洁器形成为安装于口腔护理器具头部上的弹性体垫片,用于改进清洁、方便制造并让使用者舒适。
在本发明的另一个方面,组织清洁器包括至少一个凸出部,其从沿器具的头部延伸的材料的基部突出。在一个实施例中,多个凸出部沿垫片以间隔的关系沿头部延伸,垫片形成为固定在头部上的长形带。在一个构造中,基部叠加在一般为硬的头部结构上。备选地,基部一体形成为头部的部分,由此形成柔性的头部。
在本发明的另一个方面,软组织清洁器包括至少一个长形脊体和多个凸起或具有非长形结构的其它离散凸出部的结合。因此,舌头和嘴里其它软组织以两种类型的清洁器凸出部的优点而清洁,用于增强清洁效果。
在本发明的另一个方面,软组织清洁器包括硬的凸出部和软的凸出部的结合,以清洁舌头和嘴里其它软组织。在一个构造中,清洁器包括多个软凸起和至少一个长形的硬材料脊体。这样,软清洁器和硬清洁器的结合的优点可在一个器具中获得。
在本发明的另一个方面,软组织清洁器包括至少一个带有刮擦边缘的凸出部,以在舌头或其它组织上移动。该边缘由具有不同斜度的倾斜表面形成。在一个构造中,陡峭的斜坡大体上朝向手柄,以便在头部拖出嘴时提供更激烈的刮擦动作。较浅的表面使凸出部不易于推动舌头生物薄膜进一步向后而进入喉咙。
在本发明的另一个方面,口腔护理器具包括基座以促进并便于将组织清洁器模制到头部上。在一个优选的构造中,头部具有一个或多个突起,用于在组织清洁器模制时锚接头部。头部还可包括盆形部,以进一步限定模制的组织清洁器的轮廓。
在本发明的另一个方面,口腔护理器具包括组织清洁器,组织清洁器具有用于从使用后两小时测得的基准减小35%的口腔挥发性硫化物的机构。
在本发明的另一个方面,口腔护理器具设有牙齿清洁元件和组织清洁器,用于全面清洁牙齿、牙龈、舌头以及面颊和嘴唇的口腔表面。在优选的构造中,牙齿清洁元件和组织清洁器支撑于支撑头部的相对侧上。
在本发明一个其它方面,包括牙齿清洁元件和组织清洁器的口腔护理器具将牙齿清洁元件中的至少一个与组织清洁器形成为整体构件。

具体实施方式
在下面的描述中,本发明依据牙刷来进行描述。例如,牙刷100显示为图1中的一个实施例,且牙刷500显示为图8中的备选实施例。不过,本发明可用于包括简单组织清洁器具的其它口腔护理器具。而且,应理解的是,可利用其它实施例,且可在不脱离本发明范围的情况下进行结构和功能性的修改。
如图1至图7所示,以牙刷100形式的口腔护理器具包括手柄103和头部105,头部105可用于清洁牙齿和嘴里的软组织,例如舌头、面颊的内表面、嘴唇或牙龈。手柄103为使用者提供用于容易地握持和操作牙刷,且可由许多不同的形状和构造形成。虽然头部一般相对于手柄的颈部加宽,但在一些构造中,其简单地为手柄的连续延伸或缩窄。在优选的构造中,头部105具有第一面106,其支撑牙齿清洁元件107(图5和图6),还具有第二面108,其支撑组织清洁器300(图2和图3)。第一面和第二面106、108优选地在头部105的相对侧。不过,组织清洁器300可安装在其它地方,例如手柄103的近端104。组织清洁器300或它的部分也可位于头部105的外周侧壁表面101上,或比图示的更加向手柄103的近端104延伸。
组织清洁器300的弹性体材料可为任何适于用在口腔卫生装置内的生物相容回弹材料。为提供最佳的舒适及清洁益处,弹性体材料优选地具有A8至A35肖氏硬度范围的硬度属性。作为示例,一个优选的弹性体材料为由GLS公司制造的苯乙烯-乙烯/丁烯-苯乙烯嵌段共聚物(SEBS)。不过,也可以使用来自其它制造商的SEBS材料或在所述硬度范围之内或之外的其它材料。
组织清洁器300优选地配置有多个组织接合元件303(图1至图4),组织接合元件303在优选的构造中形成为凸起。如下面所述的,备选的凸起构造502也在图8至图12的备选构造中图示说明。本文所使用的“凸起”大体上是指包括从基部表面直立的类似柱状的突起物(不限于突起物的截面形状)。一般而言,在优选的构造中,凸起的高度大于凸起基部处的宽度(在最长方向测量)。不过,凸起可包括凸出部,其中宽度和高度大略地相同,或其中高度稍小于基部宽度。而且,在某些情况下(例如,凸起渐缩至顶端,或包括缩窄至更小凸出部的基部部分),基部宽度可远大于高度。
此组织接合元件303设计为大大地减少人群中不良气味的主要来源,并改进卫生。凸起303能够从舌头和嘴里的其它软组织表面移除微生物群落和其它碎屑。特别地,舌头易于产生细菌覆层,细菌覆层驻留有机物和碎屑,促进不良的气味。此微生物群落可在大部分舌头上表面上的舌乳头之间的凹部发现,也可在沿嘴里的其它软组织表面发现。当贴着舌头表面接合或拉动时,例如,弹性体组织清洁器300的凸起303提供与软组织温和的接合,同时向下进入与相邻舌乳头的凹部。组织清洁器300的弹性体构造还使基部表面301能够沿口腔组织表面,例如使用者的舌头、面颊、嘴唇和牙龈的自然轮廓行进。而且,当需要横穿并清洁嘴里的软组织表面时,软凸起303能够挠曲,软凸起303沿着该表面移动。
如图2和图4所示,在组织清洁器300的一个优选的设置中,凸起303优选地以成圆锥形成形。当用于本文中时,“成圆锥形成形”或“圆锥形”意味着包括真正的锥形、截锥成形元件,以及渐缩至窄端并因此类似锥形的其它形状,而不管它们在锥形上是否一致、连续或具有圆形的截面。参照图4,各成圆锥形成形的组织接合元件303的基部部分305大于相应的顶端部分307。在此成圆锥形成形配置中,基部部分305具有更宽的截面面积,以提供有效的剪切强度来承受组织清洁器300沿舌头表面或其它软组织表面的横向运动。顶端部分307更小的宽度或直径与成圆锥形成形凸起303的长度结合,使凸起能够扫进舌头和其它表面的凹部,来清洁软组织表面的微生物引起的沉积和其它碎屑。在优选的构造中,当在使用中施加横向压力时,凸起303能够从它们各自的垂直轴线挠曲和弯曲。此挠曲增强了软组织表面的舒适和清洁。在优选的构造中,凸起的基部的厚度或宽度为0.64mm,并优选地在从约0.51mm至约2.00mm的范围内。凸起的顶端307为0.127mm,并优选地在从约0.10mm至约0.75mm的范围内,用于使用者舌乳头的凹部之间的最佳穿透。当从基部表面301至顶端307测量时,凸起303的长度或高度优选地为0.91mm,且优选地在从约0.5mm至约2.5mm的范围内,且最优选的范围是在0.75mm至1.5mm之间。不过,也可以使用在给定范围之外的其它尺寸和形状的凸起。
备选地,组织清洁元件303可具有其它形状。作为一个示例,组织清洁器可具有格栅的形式(grated form),例如在待审美国专利申请序列号10/601,106中所描述的,其通过引用结合于本文中。
在优选的构造中,凸起303以高密度的模式安置在组织清洁器300的基部表面301上。各凸起303优选地与相邻的凸起303间隔约0.5mm至约3mm的范围之间的距离;更优选地间隔的范围在0.7mm至2.5mm之间,且最优选地为1mm至2mm之间。不过,其它的间隔范围也是可以的。基部表面301上凸起303的表面密度范围优选地从每平方英寸约100至约600个凸起。在组织清洁器更优选的构造中,表面密度范围可从每平方英寸200至500个凸起,且最优选地在每平方英寸300至450个凸起之间。在一个优选的示例中,组织清洁器300包括每平方英寸的表面面积约400个凸起。表面密度特征与凸起303的高度结合使组织清洁器能够提供增强的软组织表面清洁并改进舒适性。虽然如此,也可能为其它的表面密度。
如图3所示,凸起303优选地以大体上平行于纵轴线a-a的方向以纵向排列布置。而且,凸起303以横向排列R1、R2布置在平行于基部表面301并大体上垂直于纵轴线a-a的轴线上。在一个优选的构造中,相邻的凸起303以交错的设置设于基部表面301上。例如,凸起R1和R2的相邻横向排列具有不在彼此正后面的凸起303。当第一凸起位于以纵向方向延伸的第二凸起的横向范围内时,本文将其称为第一凸起在第二凸起的“正后方”。此配置能通过促进微生物群落和其它碎屑的移除而改进软组织表面的清洁,特别是从舌头的相邻舌乳头的凹部。虽然如此,凸起也可能随便地或以多种不同的模式设置。
舌头清洁器300优选地由模制到头部105上而形成,但也可以使用其它的制造工艺。参照图1和图4,组织清洁器300优选地模制在头部105的面108内的盆形部或接收腔111内。接收腔111具有较低的基部表面113和远离较低的基部表面113延伸的外周侧壁115。在一个安装设置中,组织清洁器300的凸起303是暴露的,用于与组织清洁器300的基部表面一起使用,组织清洁器300的基部表面相对于头部的表面114齐平或凹陷。不过,也可能为其它定位。组织清洁器的基部表面301还可能嵌入头部105或由另一个层覆盖,而凸起303穿过适当的开口凸出。
如图1和图4所示,面108还优选地包括一个或多个栓构件117a-c,其布置于盆形部111内。栓构件117形成贴靠相对模具的锚接点,以防止头部在注塑的压力下移动。因此,组织清洁器300优选地包括一个或多个补充的开孔311a-c,其暴露栓构件117a-c的顶部。虽然栓图示为沿头部中心线(例如纵轴线a-a)以直线排列,但栓可具有许多不同的位置。而且栓和盆形部优选地都包括在头部105中,但任一个都可不需要另一个地使用。
备选地,可提供盆形部111和栓构件117a-c,以便安置和保持预先模制的组织清洁器,但这些构造不是必须要使用此预先模制的组织清洁器。
栓构件117a-c可采用多种形状和长度。继续参照图1和图4,头部105包括栓构件117a-c,其远离盆形部111的较低的基部表面113延伸,至外周侧壁115的高度。栓构件117a-c以圆柱的形式而成形,但栓构件117a-c的其它形状和长度也是可以的。虽然优选用模制工艺将组织清洁器结合到头部,但组织清洁器可通过粘结或其它已知的方式实现或者附接。
如图1至图4所示,组织清洁器300优选地形成为由软且柔韧的弹性体材料组成的垫片,以舒适地清洁并有效地除去沉积在舌头表面、嘴里其它软组织上,甚至沿嘴唇沉积的细菌和碎屑。组织清洁器300还提供有效的按摩、刺激,并有效移除舌头表面、面颊、牙龈或嘴唇的细菌、碎屑和上皮细胞。
在优选的构造中(图1至图6),当使用者刷牙时,组织清洁器300可贴着面颊或嘴唇的内表面并在舌头的侧面上摩擦,并因此提供所希望的按摩、刺激和嘴里各种软组织表面的清洁。例如,在正面的牙齿表面的刷洗过程中,组织清洁器300置于头部105的外面108,以自然地贴着面颊的口腔表面摩擦。因此,可获得增强的清洁而不需要额外的清洁步骤。而且,一些使用者可在面颊表面上感觉到刺激感,这种刺激感产生正面的使用者反应,而且甚至是组织清洁器沿嘴里软组织表面的愉悦的舒适感觉。组织清洁器300也可如所希望地另外在面颊、舌头等上面进行摩擦,用于除了刷牙时可能出现的接触之外的进一步的清洁。
参照图5和图6,头部105的牙齿清洁元件107可包括多种可用于擦拭、清洁、按摩使用者牙齿和牙龈的牙齿清洁元件。可使用任何形式的牙齿清洁元件。用语“牙齿清洁元件”以一般的理解使用,其指细丝硬毛或者具有任何所希望形状的弹性体指状物或壁。在所示的图5的示例中,牙齿清洁元件107包括布置在头部105的远端顶部121处的远端牙齿清洁元件203a-b、外周牙齿清洁元件205a-1、沿纵轴线a-a布置的纵向牙齿清洁元件207a-c、弓形牙齿清洁元件209a-d和211a-b、以及近端清洁元件213a、b。牙齿清洁元件205、207、211和213优选地提供为硬毛丛,而牙齿清洁元件209优选地形成为弹性体壁。不过,也可以使用其它形式和类型的牙齿清洁元件。
图7示出了牙刷头部400的备选设置的截面图。头部400在构造上与头部105相似,除了牙齿清洁元件209a-d是与组织清洁器300整体形成之外。为实现此备选的构造,头部400具有合适尺寸的端口或开口401,以允许弹性体材料在注塑工艺中穿过头部流动。在此构造中,牙齿清洁元件209a-d和组织清洁器300以相同的弹性体材料形成。因此,头部400可包括至少一个弹性体的牙齿清洁元件,其与组织清洁器300形成整体的构件。
在图8中,牙刷500包括从头部506后侧面504突出的多个凸起或其它凸出部502,作为嘴里软组织的清洁器508。牙齿清洁元件516优选地从头部506的前侧505延伸。凸出部502优选地沿至少一个窄的基部或垫片逐一设置,基部或垫片以固定在头部506上的带510的形式。在所示的示例中,多个大体上平行的带510a、510b、510c、510d以远离手柄地朝向的大体上凹入的形状固定,在此一个构造中,带沿着头部506的后侧面504和各个侧壁511延伸,但沿侧壁的延伸不是必须的。可以包括任何数量的带。带可以在头部上实质上限定任意的形状或方位。例如,带510可具有在2004年11月17日提交的,名称为“口腔护理器具”,并具有律师档案号006427.00131的待审美国专利申请序列号10/989,267中公开的任意用于脊体的形状,其通过引用结合于本文中。在所示的构造中,带510由轴向杆512相互连接,轴向杆512延伸进入手柄并形成给使用者的握把的一部分。而且,此手柄延伸部或甚至是杆当然不是必须的。
在一个构造中,各凸出部502大体上为柱形,并以约1.1mm的宽度W,约1.7mm的高度H形成(图9)。凸出部沿带510相互间隔开约1.0mm的距离。但这些高度、宽度和间隔尺寸可以大范围地变化。在所示的实施例中,凸出部502各包括从基部510向外突出的外周壁513,以及对头部506的侧面504以约50度的角度倾斜的远端表面514。倾斜的端表面514沿部分外周壁513限定窄的顶部边缘516,其有益于清洁舌头和其它软组织。尽管端表面514显示为以相同的方向倾斜的,但它们也可以以不同的方向倾斜。
在备选的构造中(图13),头部506另外形成至少一个长形的脊体525。以此设置,为使用者提供了清洁器,通过越过舌头或其它组织移动离散的凸出部502和脊体525可获得有益的双重清洁效果。在所示的示例中,脊体525为弧形的、长形的凸出部,其大体上沿头部远端527的外边缘向外突出。不过,其它的设置、位置和形状也是可以的。也可以提供另外的脊体。在一个优选的构造中,脊体525与头部整体模制,并由相对硬的塑料例如聚丙烯形成。但脊体也可与头部分开形成,和/或由其它适用于口腔护理器具的材料组成。
在一个构造中,如上所述,脊体525由相对硬的材料(例如,聚丙烯)形成,同时凸出部502由相对软的材料(例如,热塑性弹性体形成)。双重材料的使用能够获得两种材料的优点。清洁器包括脊体525内相对硬的刮擦器刀片和在挖入舌头或其它组织时挠曲并转动的相对软的离散凸出部的可靠接合。
如图13和图14所示,脊体525由一对相对的侧壁533、534限定,侧壁533、534相遇形成刮擦器边缘535。虽然边缘535在此构造中相对较窄,但可以大致加宽。在一个实施例中,侧壁533、534以相对于头部506的侧面504的不同的斜坡形成,但它们可以具有相同的斜坡。在一个优选的构造中,侧壁533以比侧壁534更陡峭的斜坡形成,以便当由使用者拉动头部越过舌头时,形成更强烈的刮擦动作。朝向大体上远离手柄的侧壁534的较浅的斜坡,在当脊体朝向喉咙向后推时,使脊体不易于推动舌头生物薄膜进一步向后到喉咙内。在优选的实施例中,侧壁533以相对于侧面504的角度α为62度定向,而侧壁534以角度β为43度定向。其它的角度也可以用于这两个侧壁。
在另一个备选的构造中(图10),各凸出部502a设有端表面514a,其具有两个倾斜的端面部分515a、517a和顶部边缘516a。如同脊体525的情况一样,大体上朝向手柄的端面部分515a优选地以相对于侧面504a比端面部分517a更陡峭的角度倾斜,但也可以使用包括具有相同倾斜度的端面部分的其它设置。作为一个示例,端面部分515a以相对于侧面504a的角度α为62度定向,而端面部分517a以角度β为43度定向。当头部从嘴里拖出时,端面部分515a更陡峭的角度提供了更激烈的刮擦动作。端表面517a较浅的角度使凸出部不易于推动舌头生物薄膜进一步向后到喉咙内。
当然,也可以使用其它凸出部。例如,各凸出部可以包括不倾斜的远端或渐缩至尖顶的端部。除了图8所示的圆柱形状外,凸出部可具有宽范围变化的形状。例如,凸出部可具有圆锥形形状、不规则截面、或倾斜于后侧面504。而且,凸出部也可成形为完全或部分地沿带510的长度延伸的脊体。
在优选的构造中,凸出部502和带510成形为模制的或是另外紧固于头部506的整体构件。凸出部和带优选地形成为回弹热塑性弹性体的整体构件,例如由GLS公司制造的苯乙烯-乙烯/丁烯-苯乙烯嵌段共聚物(SEBS),但也可能由其它的回弹材料、硬材料、或例如2004年12月15日提交的,名称为口腔护理器具,且律师档案号为006427.00132的美国专利申请序列号11/011,605中所公开的材料的结合,该专利申请通过引用结合于本文中。凸出部和带也可由与头部506相同的物质(例如,聚丙烯)形成,但具有不同的颜色等等,以限定其与头部为不同的材料,并因此至少产生视觉上吸引人的牙刷。
在一个构造中,带510模制为平置于头部506的大体上平坦的表面504上(图9)。不过,槽道507可形成于侧面504内,以在其中容置带510,使得侧面504和具有凸出部502的带510的外表面512大体上共面(图11)。此外,回弹材料的带可形成为头部构造的主要部分(图12)。具体地讲,在此备选的构造中,头部包括由回弹的第二构件522结合在一起的多个第一构件520,第二构件522作为活动绞链在牙刷使用过程中允许第一构件彼此相对移动。第二构件也形成设有凸出部502的软组织清洁器508的基部510c。此外,如在关于牙刷400中所讨论的,凸出部502或502a可与从头部以相对的方向延伸的弹性体的牙齿清洁元件一体形成为整体构件。
在另一个备选构造中(图15),牙刷600包括上述备选方案中的任一个的软组织清洁器602,或使用回弹材料的其它中的任一个的软组织清洁器602。在此实施例中,清洁器602的一部分绕头部606的侧壁611缠绕,并包括回弹构件615,回弹构件615从头部凸出,以便当沿着牙龈线应用牙刷时,提供例如,牙齿和牙龈的清洁和牙龈的按摩。在一个示例中,清洁器602具有类似于图8或图13中的清洁器的构造。以带形式的基部610越过头部606的后侧604并在侧壁611之上延伸。基部优选地由软的、弹性体材料例如热塑性弹性体(例如,SEBS)形成,但可能由其它回弹材料形成。回弹构件615优选地与平置在侧壁611上的基部的部分形成为整体。如图15所示,回弹构件615从侧壁611以与牙齿清洁元件616大体相同的方向凸出。不过,它们能备选地倾斜以横向向外延伸。另外,尽管回弹构件615显示为朝头部606的自由端倾斜,但它们可以相对侧面605以直角延伸,以其它方向倾斜,或具有不一致的定向。
可对上述方法、组成和结构进行各种变化而不脱离本发明的范围,包含在本申请中的所有内容(包括上述所有的机制和/或相互作用模式)应理解为示例性的而不以任何方式限制所附的权利要求的范围。
下面的示例作为本发明改进操作的代表而进行了阐述。这些示例不应理解为对本发明范围的限制。
示例1
牙刷的性能可使用已知的口腔恶臭评估方法来测量。已进行研究来评估设有弹性体组织清洁器的牙刷的性能,弹性体组织清洁器具有成圆锥形成形的凸起,例如上述牙刷100的优选构造。人体测试对象参加了研究。在大约7天的测试期之前有一段清洗或正常化时期,在测试期中,测试对象使用氟化物牙膏(见表1)一天两次地刷牙。在清洗期过后,要求测试对象在口腔测试之前避免任何的口腔卫生(刷洗、漱洗、使用牙线)、吃和喝。从各测试对象获取基准的挥发性硫化物(VSC)样本。在晚间气味的研究中,测试对象用氟化物牙膏(见表1)使用设有上述组织清洁器300的牙刷100刷牙一分钟。随后,测试对象以牙刷的组织接合元件清洁他们的舌头表面十秒钟。测试对象在晚间睡觉,并返回进行后处理。从前一天清洁后在10小时的时候获取VSC样本。在示出的示例中,当从使用后10小时的基准测量时,牙刷的使用与只刷牙相比减少了口腔VSC约60%。VSC读数由气相色谱法获得。
示例2
在上述牙刷100的另一个研究中,在大约7天的测试期之前有一段清洗或正常化时期,在测试期中,测试对象使用氟化物牙膏(见表1)一天两次地刷牙。要求测试对象在测试之前避免任何的口腔卫生(刷洗、漱洗、使用牙线)、吃和喝。在清洗期过后,通过以消过毒的棉拭擦舌头后部的一侧,测试对象提供基准的舌头细菌样本。测试对象用氟化物牙膏(见表1)使用设有上述组织清洁器的牙刷刷牙一分钟。随后,测试对象以牙刷100的组织接合元件300的优选构造清洁他们的舌头表面十秒钟。清洁舌头表面两小时后,使用棉拭从舌头后部的一侧获取舌头细菌样本。在示出的示例中,组织接合元件的使用比只是简单地刷牙控制了更多由舌头细菌产生的气味。组织清洁器300的使用证明使用后两小时在舌头上舌头细菌对数减少超过0.8菌落团生成单位的对数/毫升(Log colony forming units/ml)。
示例3
在上述牙刷的另一个研究中,MTT化验用于检验在使用带有上述组织清洁器的牙刷之前或之后从口腔采集到的上皮细胞的生存能力。MTT化验基于活的、代谢活动的细胞中四唑盐MTT(四甲基偶氮唑盐)酶的减少。反应在测试管中在原位实现,且反应产物(可溶解在二甲亚砜中的紫色的甲腊(formazan))利用多个培养板读数计进行颜色度量上地测定。有益的是,MTT化验提供了高的精度、方便使用、并适于用作大规模化学敏感性测试的目的。
7天的清洗期后,测试对象在吃、喝或进行口腔卫生前,报告测试情况。测试对象通过以9ml消过毒的水漱洗他们的口腔10秒钟提供唾液的漱洗样本,然后从漱洗中排出水进入包含10x消过毒的磷酸盐缓冲盐水(PBS)溶液的管。在进行MTT化验前冷却样本大约30分钟。测试对象在监督下用氟化物牙膏(见表1)刷他们的牙齿一分钟,然后以优选构造的舌头清洁器300进行10秒钟的舌头清洁。在刷洗和舌头清洁后大约30分钟,测试对象以上述同样的方式提供漱洗样本。
漱洗前样本和漱洗后样本用离心机以约3000RPM分离15分钟。上层的,例如清液,被移除且颗粒物重新悬浮在2.5ml的PBS中。样本涡旋5秒钟。然后增加2.5ml的MTT溶液。样本随后培养在轻轻摇动的设在37℃的水浴中2小时。2小时的培养期过后,样本用离心机以约3000RPM分离15分钟。虹吸出上清液并加入3ml清洁剂(0.04N酸性异丙醇)来溶解紫色晶体。MTT转变的增加或减少由分光光度计确定。从各样本中,各自的200μl加入到96培养板,且光学密度在570nm处测量,并与负缓冲控制相比较。在所示的示例中,当由MTT化验规程确定时,刷牙一分钟后使用组织清洁器10秒钟减少了约72%的口腔上皮细胞。
示例4
在另一个研究中,人体测试对象经由HalimeterTM(即硫化物测量计)提供基准的VSC样本。HalimeterTM使用电化学、伏特安培计传感器,当暴露于VSC例如硫化物和硫醇气体时其产生信号,并测量硫化氢气体的十亿分率浓度。测试对象在监督下以具有上述组织清洁器的牙刷的优选构造刷他们的牙齿一分钟。然后,测试对象使用上述牙刷在舌头表面上提供六个行程。随时后的VSC样本在刷牙后2小时从测试对象获取。在所示的示例中,带有组织清洁器的牙刷的使用从使用后两小时所测得的基准减小了在嘴里气味中所测得的VSC超过35%。
示例5
在一个其它研究中,在清洗期后,人体测试对象以消过毒的水漱洗他们的嘴,以提供基准样本用于以MTT化验进行能存活的上皮细胞分析。该对象在监督下以具有上述组织清洁器的牙刷的优选构造刷他们的牙齿一分钟。然后,测试对象使用组织清洁器在舌头表面上提供6个行程。测试对象提供漱洗后的样本用于分析。以对示例3所讨论的方式测试和分析样本。在此示例中,牙刷的使用从由MTT化验规程所确定的基准减少口腔上皮细胞约92%。
在上述示例中,该对象使用具有表1中配方的氟化物牙膏刷他们的牙齿。
