Abstract
本發明係有關一種使用在治療或預防侵蝕性的牙齒去礦化、牙菌斑和齲齒之口腔保健組成物。此口腔保健組成物包括乳酸鋅二水合物、亞錫離子源、至少一磷酸鹽以及一緩衝液系統。
Description
本發明係關於治療或預防侵蝕性的牙齒去礦化、牙菌斑和齲齒用途的口腔保健組成物。此種口腔保健組成物包括乳酸鋅二水合物、一種亞錫離子源、至少一種磷酸鹽和一緩衝液系統。
牙菌斑是一種常見於牙齒之間、在齦線上、以及齦線邊緣下方的黏性生物膜或大量細菌。牙菌斑可引起齲齒牙周問題,諸如牙齦炎和牙周病。齲齒或牙齒去礦化是由細菌分解可發酵糖所產生的酸所引起的。
含亞錫離子源的口腔保健組成物展現優異的臨床益處,尤其是在減少牙齦炎和治療或預防侵蝕性的牙齒去礦化。然而,調配具有亞錫離子源的口腔保健組成物可能會有困難。一個理由是因為亞錫離子可能不穩定並且其他在該口腔保健組成物中的成分反應,形成不溶解之不具活性的錫化合物,從而減少組成物中可獲得的亞錫離子量。一種克服亞錫離子穩定性的方法是限制組成物中水含量至非常低的程度,或者使用一個雙相的系統。這兩種亞錫離子問題的解決方法都有缺點。低含水量的口腔保健組成物可能很難用想要的流變性質來調配,並且製造和包裝雙相的組成物相當地更加昂貴。
因此,吾人需要提供改進之含亞錫離子產品以抗微生物效力治療和預防牙齒琺瑯質遭侵蝕,減少牙菌斑或治療或控制牙齦炎。
本發明所揭示的是包含乳酸鋅、亞錫離子源、至少一磷酸鹽和一緩衝液系統的口腔保健組成物。此種組成物的方法和用途亦被徹底說明。本文中所揭示之組成物相較於先前技藝係提供了強化的去礦化防護並且增進抗細菌的活性。
經由本說明書其後所提供的詳細說明,本發明之更多應用領

代表性調配物
以下提供本發明之一例示性組成物A(實例2),以及對照組和兩個比較用的市售組成物(比較用的組成物A,比較用的組成物B)之去礦化/再礦化研究。該對照組的組成物除其含有0.12%氟化亞錫以替代0.454%氟化亞錫之外,與實例2完全相同。比較用的組成物A是一種市售的牙膏調配物,其含有氟化鈉但不含亞錫或鋅離子用劑。組成物B是包含氟化亞錫、乳酸鋅和六偏磷酸鈉的市售牙膏調配物。兩種市售比較用組成物均缺乏任何羧酸緩衝液系統。實例2的調配物和組成物B顯示在以下表2之中:
吾人對於實例2的潔牙劑、一對照組樣本、和兩個比較用的實例進行試驗。在去礦化/再礦化研究期間,所有樣本均被取樣通過10天的pH循環。全面地將牙齒浸泡在加熱過的唾液中以形成薄膜。接著將其一天兩回佣1:2牙膏糊狀物處理並且接受三回為時2分鐘之1.0%檸檬酸溶液酸挑戰。使用共軛焦顯微成像術(Confocal microscopy)定量琺瑯質的去礦化。結果顯示在以下表3之中。
用實例2的潔牙劑組成物試驗的牙齒僅顯示21.63%的礦物質流失,而未經處理的牙齒(對照組)展現75.56%的礦物質流失,且用比較用組成物A和比較用組成物B處理的牙齒分別展現71.29%和53.12%的礦物質流失。因此,實例2的潔牙劑組成物與先前技藝之組成物相比,展現其能增進牙齒防護以對抗礦物質流失。
實例2的潔牙劑組成物和比較用組成物實例的抗微生物性質研究是在一個厭氧的生物膜模式中進行的,該模式含有格蘭氏陰性厭氧菌在飽含啶酮酸和萬古黴素的瓊脂上。將細菌培養物在厭氧條件下培養在羥磷灰石(HAP)培養皿上至隔夜以先長出生物膜。然後用試驗組成物對培養皿進行處理,每天兩次經五天,這也是在厭氧條件下進行的。第五天,僅處理HAP培養皿一次使生物膜得以再生長。然後將HAP培養皿塗抹5%山羊血並留置隔夜以使菌落長成。然後計算菌落並且將之報告為log10菌落形成單位/mL(CFU/mL)。結果顯示在以下表3中。
如表4說明的數據所描述,本發明揭示內容之範例組成物展現其與比較用組成物相比之較高的抗細菌效力。試驗調配物A和比較用的市售組成物B、C和D相比,在試驗期間展現其統計學上顯著較佳地抑制細菌生長效力。
比較用組成物B是用於以上礦物質流失的市售比較用組成物。比較用組成物C和D是相似於B的市售組成物,其每一者含0.454%氟化亞錫、2.5%乳酸鋅和六偏磷酸鈉,且其亦缺少羧酸緩衝系統。
通貫本說明書中使用的,範圍係以簡略方式用於說明在該範圍內的每一數值。任何在該範圍中的數值可被挑選作為該範圍之邊界值。此外,所有本文中引用的參考文獻係以全文引用方式併入本文中。當與本發明揭示內容和引用的參考資料中的定義相牴觸的情況下,則以本發明揭示內容為主。
除非另有指明,否則所有本文各處所表示的百分率和用量應被瞭解係指重量百分率。所提供的用量是根據該物質的活性重量。
雖然吾人以實施例為參考對本發明作說明,但是熟習本技藝者應了解各種在其中的修改和變更並不會偏離所附申請專利範圍定義之本發明的範疇。
