Description
技术领域
本发明涉及口腔护理技术领域,具体说是一种牙科基质辅料及其制备方法。
背景技术
口腔疾病主要是指口腔受到了外界因素的影响、细菌或病毒的入侵或者牙龈发育异常等原因造成的病理性现象。常见且高发的口腔疾病主要有:牙龈炎、牙周炎、口腔溃疡、鹅口疮等,义齿清洁不当也会导致口腔疾病。
对于由细菌引起的口腔疾病,根据严重程度的不同常采用不同的治疗方式。常用的治疗方式以机械去除牙菌斑为主,辅以口服抗生素、外用氯己定类含漱剂等治疗方式。口服抗生素虽然比较方便,是最常用的给药途径,但是口服药物吸收后,经血液循环转运至病患部位的药物浓度有限,效率有限。外用氯己定类含漱剂能有效地控制龈上菌斑,降低牙龈炎症,是临床上常见的治疗牙周炎的药物,但含漱剂对龈下菌斑的抑制作用不大,且随着口腔唾液的分泌与进食,会降低有效抑菌成分的浓度,需要多次使用才能维持口腔内抑菌成分的浓度,有效控制口腔细菌的增长。
综上,针对常见口腔疾病,如溃疡、牙周炎、牙龈炎,采用片剂、液体喷剂、含漱剂、凝胶剂等传统方式进行治疗,容易受患者唾液分泌、咀嚼动作影响,导致作用部位(病患部位)再次暴露,无法持续发挥药物作用,治疗效果较差。
因此,需要研究针对口腔疾病的局部给药、长效抑菌的解决方案。
公开于该背景技术部分的信息仅仅旨在加深对本发明的总体背景技术的理解,而不应当被视为承认或以任何形式暗示该信息构成已为本领域技术人员所公知的现有技术。

佩戴义齿导致的口腔粘膜发炎(口腔黏膜损伤感染):清洁口腔和义齿后,采用本发明所述牙科基质辅料,联合维生素E和聚六亚甲基双胍,喷洒适量维生素E和聚六亚甲基双胍溶液于患处,涂抹牙科基质辅料于义齿与口腔接触部位,牙科基质辅料本身的柔软特性以及接触唾液后表面凝胶层的形成,既能减少义齿带来的摩擦,又能加速已磨损粘膜区域的修复,同时持续的抗菌作用,能够有效预防菌落沉积与生长。
口腔溃疡、鹅口疮:清洁口腔后,采用本发明所述牙科基质辅料,联合维生素E和葡萄糖酸氯己定,在病患部位喷洒适量维生素E和葡萄糖酸氯己定溶液后,取牙科基质辅料涂抹于该部位;维生素E能有效改善创面愈合情况,葡萄糖酸氯己定能有效抑制消杀病患处富集的细菌;牙科基质辅料能形成有效物理屏障,提高药物利用率。

实施例1溶解时间测试(实施例2-4溶解时间测试结果大致相同,故省略)。
对实施例1中所得成品,依据如下方法进行溶解试验,以表征该材料在模拟口腔唾液环境下的崩解时间。
人工唾液按照ISO/TR10271方法配制,成分如下:NaCl 0.4g,KCl 0.4g,NaH2PO4·2H2O 0.78g,Na2S·2H2O 0.005g,尿素1.0g,CaCl2·2H2O 0.795g,纯化水1000mL。
用NaOH和HCl溶液调整人工唾液的pH值为6.0,保存在4℃冰箱中备用。
取实施例1样品1g,将其制成球形后,按压在规格为250mL的烧杯壁上并塑形,使其成为直径约1.6cm的圆形样块,加入100mL人工唾液,加入长度为3cm的转子,在37℃、200rpm下搅拌至完全溶解,观察溶解状况。该样品在模拟口腔唾液环境下能够持续保留约24h。样品溶解状态随时间变化图参见图2.a至图2.f,分别是4h、8h、12h、16h、20h、24h的溶解状态。
实施例1稠度测试(实施例2-4稠度测试结果大致相同,故省略)。
对实施例1中所得成品,依据如下方法进行稠度试验,以表征该材料在使用过程的柔性特征。
取实施例1样品1g,将其制成球形并放置于玻璃板上,覆盖大小为5cm×5cm的称量纸后,将500g标准砝码垂直放于样品中心正上方,停留30s后,移除砝码,使用精度为1mm的量具测量样品形变后的直径大小(如果是椭圆,则取其长短轴的平均值),结果如图3所示。根据所得结果,该材料在外力作用下发生形变后的直径大小约为28mm,该特性有利于实际使用过程中对其进行塑形,以适应更为复杂的创面形状。
实施例2-4模拟载药释放率。
分别取实施例2、3、4所得的膏体各1g,将其分别与10mg模拟止痛药物萘普生钠混合包裹后,制成球形并粘贴于烧杯壁,再分别在烧杯中加入200mL pH为6.8的PBS缓冲溶液,于37℃、100rpm条件下振荡,模拟释放。
精确称取萘普生钠药物12.5mg,将其稀释配制成系列浓度(10,20,30,40,50mg/L),用紫外分光光度计测量270nm处萘普生钠药物的吸光度得到标准曲线。
自4h、8h、12h、16h、20h、24h取烧杯溶液进行测试,并根据标准曲线计算得到释放率。结果如下表所示。绘制成释放曲线如图4所示。
三种配比均未观察到药物突释,且药物随材料逐步崩解释放出来,且具有良好的药物缓释效果,其中24h后,实施例2、3、4的药物释放率分别为81.98%、90.56%、96.34%,实施例2表现最佳,主要由于该配比条件下,聚醋酸乙烯酯、醋酸乙烯酯-月桂酸乙烯酯共聚物形成的疏水网络更佳牢固,具有更佳的药物释放控制效果。
以上所述实施例1-4是本发明一部分实施例,而不是全部的实施例。实施例的详细描述并非旨在限制要求保护的本发明的范围,而是仅仅表示本发明的选定示例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本说明书中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
以上所述仅为本发明的较佳实施方式,本发明的保护范围并不以上述实施方式为限,但凡本领域技术人员根据本发明所揭示内容所作的等效修饰或变化,皆应纳入权利要求书中记载的保护范围内。
