糖尿病患者 應注重口腔清潔



港人對糖尿病及牙周病這兩個名詞不會感到陌生,但只有少數人知道糖尿病人是牙周病的高危族。研究顯示,糖尿病患者牙周組織免疫力較一般人低,容易誘發牙周 病。同時,他們口腔唾液內血糖含量較高,易與細菌產生化學作用,形成酸性物質腐蝕牙齒,增加患牙周病風險。加上患者口腔唾液分泌少,易口乾,令細菌及牙菌 膜在口腔內積聚,在未能及時清潔的情況下,分泌酸性物質腐蝕牙齒,產生有毒物質,刺激牙齦等牙周組織,導致牙周病等口腔疾病。

降低糖尿病患者牙周病的風險,需有效控制血糖及維持口腔衞生。由提高自身免疫力着手,降低口腔內血糖含量,改善口乾問題; 同時,更應注意日常的口腔保健,盡量減少口腔內細菌及牙菌膜堆積。建議每日至少刷牙兩次,於每次飲食後刷牙為最佳,能及時清潔殘留於牙齒表面的牙菌膜。然 而,單靠刷牙並不能全面清潔口腔,有研究指出,單靠刷牙只能清潔百分之二十五口腔表面,仍有百分之七十五布滿細菌,成為口腔疾病的溫床。

因此,建議同時配合使用牙線,及含抑菌成分的漱口水全面清潔口腔,降低患牙周病的風險。

Sensitive teeth

If enamel has been worn off or damaged, then it will lose its protective function and the dentine will be exposed. The dentine has many fine dentinal tubules connecting to the pulp. The patient will suffer sharp pain when feel stimulated.


To protect from damaging enamel, you should not brush with a toothbrush with bristles that are too hard, or brushing with excessive force can abrade the enamel of teeth. Also, you should avoid frequently eating or drinking highly acidic food or beverages and frequent grinding of teeth.



What is/are the treatment(s) for sensitive teeth?

1) Apply topical fluoride on the tooth surface or perform a filling according to the condition in order to obstruct the exposed dentine tubules.

2) Use desensitizing toothpaste to relieve tooth sensitivity. You should consult your dentist before purchasing or using this type of toothpaste.

3) Use a “mouth guard” made by the dentist to avoid further attrition of teeth.

定時洗牙, 擊退牙石


 
 
病從口入,不少病菌都是經由口腔進入體內,又濕又暖和的口腔更是細菌最佳的藏身處。其中,因護理不足使牙菌膜積聚鈣化而形成的牙石,其結構還為細菌提供更多躲藏空間,促使牙周病出現。況且牙石容易「上色」,使牙齒變得啡黃,大損儀容,因此大家不得不小心牙石來襲。


鈣化形成牙石


為何口腔內會無端端出現牙石呢?原來牙石就是鈣化後的牙菌膜,牙科醫生王志偉表示,口腔內 每天都會不斷有牙菌膜積聚,需要每天刷牙及用牙線將牙菌膜清除。當我們口腔護理不足或沒有好好養成正確的口腔護理習慣的話,牙菌膜就會慢慢利用唾液中的礦 物鹽而逐漸鈣化。而鈣化後牙菌膜會由透明柔軟變得灰白堅硬,那便是我們所說的牙石。王醫生指出牙石形成後便不能輕易刷走,而且其表面凹凸不平,食物色素容 易依附其上,特別是經常吸煙、喝咖啡的人,被染色的牙石會使他們的牙齒變得格外啡黃,非常影響外觀儀容。


間接引致牙周病

當然,牙石積聚不單止影響外觀,王醫生指出:「牙石表面多孔的結構使它更容易積聚污物細 菌,亦會使刷牙時更難以清潔,因此牙石的多少,一般與牙周病是成正比例的。」此外,王醫生指出,牙石在鹼性的環境會更易形成,而口水除了含礦物鹽外,一般 亦是偏鹼性的,舌底和口腔兩邊是唾液腺排放口水的出口,因此這兩處附近會特別容易積聚牙石。至於一般市民如何能知道自己有沒有牙石問題呢?王醫生就說一般 可靠目測,因牙石特別易上色,所以牙肉邊緣顯得特別啡黃的話就應該有牙石問題。此外,牙齒因本身不是一粒粒方正的四方體,牙齒的弧度在排列時必定會有縫 隙,所以如果你用舌頭觸碰牙齒背面時感覺不到凹凸不平,那同樣有可能出現牙石問題。


洗牙不怕牙齒磨損

雖然牙石不能透過刷牙清除,不過只要找合資格的牙醫處理,其實不難除掉。王醫生指出,一般 可以用手工具刮除牙石和用超聲波將牙石震散兩種清除方法。牙石雖然堅固,但仍遠不及牙齒本身的硬度,所以用儀器一般只會刮走牙石,不用擔心會磨損牙齒。而 超聲波技術,現在大部分牙醫均已採用,可以不怎麼費勁就能將牙石震散沖走,對牙齒本身的影響也非常輕微。王醫生表示,如果有能力把所有牙菌膜都清除的話, 不一定要定期洗牙;可是一般人都不能百分百做到完美,況且定期找牙醫不只為了洗牙,也要檢查其他問題(例如蛀牙),所以一般建議半年至一年必須找牙醫檢查 及洗牙一次。不過如果本身牙齒不齊、佩戴假牙或會增加清潔的困難,就可能要檢查得頻密一點。最後王醫生還指出,口腔在進食時其實也有自潔作用,多吃一些纖 維性重的粗糧,對牙齒健康也有幫助。與此同時,也要記着「物極必反」,過分吃這些粗糧也可能令牙齒磨損。
