Zilnic vedem diverse mesaje cu privire la renuntarea la fumat. De cele mai multe ori, asociem fumatul cu bolile pulmonare sau de inima, insa putini dintre noi stim ca jumatate din bolile gingivale ale fumatorilor sunt cauzate de acest viciu.

De obicei, primele consecinte ale fumatului sunt respiratia urat mirositoare (halitoza) si aparitia petelor cafeniu-inchis pe dinti.  Desi pentru majoritatea  implicatiile fumatului sunt in primul rand de ordin estetic, acesta duce la dezvoltarea cariilor si a afectiunilor gingivale.


Efectele fumatului nu se rezuma doar la aparitia bolilor gingivale, ci chiar ingreuneaza tratarea acestora. Fumatorii au sanse mai reduse ca un implant sa fie efectuat cu succes, iar persoanele care sufera de boli gingivale au probleme cu coroanele si puntile dentare.


Fumatul  poate agrava bolile gingivale. Unele studii au aratat ca fumatorii au mai mult tartru decat nefumatorii, acest lucru fiind cauzat de cantitatea scazuta de saliva din cavitatea bucala. De asemenea, chimicalele prezente in tigari afecteaza circulatia sangelui in gingii, incetinind procesul de vindecare a diverselor plagi, si indirect eficienta tratamentului.


Unii cercetatori spun ca, renuntand la tigari, se reduce riscul imbolnavirii. Chiar si reducerea numarului de tigari fumate pe zi poate aduce imbunatatiri semnificative sanatatii orale. Rezultatele unui studiu arata ca persoanele care fumeaza mai mult de un pachet si jumatate de tigari pe zi sunt expuse unui risc de 6 ori mai mare de a dezvolta o afectiune gingivala in comparatie cu nefumatori, iar cei care fumeaza mai putin de un pachet de tigari pe zi prezinta un risc de 3 ori mai mare decat nefumatorii.


Fumatul este unul din factorii care declanseaza aparitia cancerului oral. Un studiu al Societatii Americane de Cancer  arata ca aproximativ 90% dintre persoanele care sufera de cancer bucal si anumite tipuri de cancer la gat, au fumat. Tutunul din tigari sau pipe poate duce la aparitia cancerului in orice loc al gurii sau al gatului. Pipa poate cauza si cancerul buzelor.


Parerea specialistului:


S-ar parea ca tutunul determina distrugerea celulelor din mucoasa orala si oro-faringiana cauzand cresterea rapida a unor celule anormale in cursul proceselor de reparatie tisulara. Cercetari clinice si experimentale au demonstrat implicarea in aparitia cancerului oral a unor substante chimice ce determina modificari ale ADN-ului celular cu producerea de celule mutante. Aceste substante sunt reprezentate de gudroanele rezultate in urma arderii tutunului si a foitei de tigara in care au fost identificate aproximativ 12 hidrocarburi aromatice policiclice cu efect carcinogenetic (cele mai cunoscute fiind benz-antracenul, benzpirenul, metil-colantrenul).


Riscul aparitiei cancerului oral este in principal legat de numarul de tigari consumate pe zi precum si de perioada de timp in care s-a practicat fumatul. Riscul unui fost fumator de a dezvolta un cancer in sfera orala devine egal cu cel al unui nefumator abia dupa 10 ani de la renuntarea la fumat.”

Ce spun altii:
Being a core point guard, garage and other three split the difference is that he is the team sponsor and organizer. In other words, he can't be like novak on the perimeter around expecting kevin durant shoes someone else to provide him the ball. We take novak into a comparison, everything also - reference counted for us each a 3-pointer facilitates objects, and to occasion, after statistics, novak found shock as to hit 3-pointers, 149, 146 is often a teammate's pass and strike; Three-point shots hit the other more this season Ryan - Anderson isn't a exception, he hit curry shoes with 213, has 206 relies on your friend's passing. The garage He all the 3-pointer this season, you will discover 105 of 3 just isn't sending (272), put simply, is to create options, nasty sto vote. This trick from the team's star, such as flow of harden, vladimir radmanovic, kobe Bryant, Robert, but often because somebody errs, physical strength usage, to the number of times few, and the hit ratio seriously isn't high. But obviously is usually an exception in the Treasury, his three-point shot 105 times seriously isn't assists quantity highest throughout alliance,stephen curry shoes even better as compared to lebron James thrown in to more all 3-pointers, plus the shooting is in any league all five such not assists free-throw shooting players from the fifth (41. 8%), both equally quality and quantity. Taken together, the three points to help thrown into space seriously isn't an easy thing, will need to have the forty percent three-point shots have to create his own pictures, this how tired! By far the most precious is, no make a difference when and where, and how to make moves, garage has a superior percentage. It is no wonder the manager of the players when Bob myers not too long ago told the Associated Mass media said: "as long while it's garage, to find the ball is reasonable. ".
