Discussione:Amalgama dentario

In alcuni articoli su "aam terra nuova" alcuni naturopati hanno sostenuto che la tossicità delle otturazioni dentarie fatte con amalgama, possono dare gravi complicanze per la salute nel lungo periodo provocando gravi malattie. In quegli articoli si sosteneva anche che in Svezia l'uso dell' amalgama per le otturazioni dentarie è stato proibito per legge.

(Per mia esperienza personale concordo con quanto scritto sopra. Ho sofferto per oltre 25 anni di una grave malattia al colon che è sparita dopo aver fatto togliere quattro amalgame dentarie a seguito della lettura di quegli articoli. Non so se rientra tra gli scopi di un' enciclopedia segnalare eventuali controindicazioni all'uso di qualcosa, però visto che c'è di mezzo la salute magari una postilla, oppure un corsivo che possa mettere sull'avviso di possibili serie complicanze chi ha ancora otturazioni dentarie di amalgama sarebbe utile.

Amalgama

Mi fa piacere che venga colto lo spirito puramente divulgativo della mia voce "amalgama", era esattamente il mio intento, e più ci saranno contributi in tal senso meglio sarà. Anche io ho sofferto di mercurialismo, so di che parlo e ritengo sia ancora una grande minaccia per la salute pubblica. Gli effetti nocivi del mercurio non sono un pettegolezzo né una "cospirazione" delle multinazionali, ma una verità scientificamente accertata. Per quanto riguarda l'opportunità di inserire la sintomatologia... aspetto altri pareri a proposito, naturalmente non volevo fare l'enciclopedia medica, ma almeno far notare il collegamento tra mercurio e molti "mali moderni".

Amalgama

E' facile fare allarmismi con quello che "si sente dire". Sono odontoiatra, ancora giovane, e forse sono uno degli ultimi della mia generazione a fare otturazioni in amalgama. Tenete presente che il 95% della popolazione adulta ha otturazioni in amalgama in bocca, ma a ciò non corrisponde un'identica percentuale di malanni. Il problema amalgama è molto più complesso. Il mercurio presente nelle otturazioni realizzate in amalgama gammaII, creato a partire dagli anni '50, è legato a rame e argento. Anche se effettivamente la normale usura del materiale porta ad un certo assorbimento da parte dell'organismo (valutabile in un aumento di 3 volte della quantità di mercurio nel sangue), un pasto a base di pesce aumenta questo valore di qualche decina di volte. Nessuno si sogna di abolire per questo il pesce.

Le otturazioni cosiddette "bianche", in composito, sono realizzate con una resina a base metacrilica polimerizzata. La polimerizzazione in cavità orale non è mai completa, e i radicali metacrilici sono SICURAMENTE tossici (provate a sniffare un pò di vernice).

La verità come sempre è incerta. Comunque è interessante sapere che le otturazioni in amalgama sono MENO COSTOSE e PIU' DURATURE di quelle in composito. Per la medicina legale italiana le otturazioni in amalgama nei settori posteriori sono da ripetersi ogni 12 anni, contro i 6 del composito, ad un costo del 50-60% in meno per il paziente. Il business ora è nel composito..

Per quanto rigurda la Svezia, dove gli amalgami sono stati messi fuori legge, bisogna considerare che ciò è stato fatto non per la tossicità delle otturazioni a paziente vivente, ma per il fatto che la procedura di cremazione di un cadavere con amalgami in bocca libera vapori di mercurio. In Svezia quasi tutti si fanno cremare...E il problema riguarda l'inquinamento dell'aria...Per il quale penso che si potrebbero tirare in ballo problemi più pressanti...

Da odontoiatra giovane anche io, ti dico che nella mia opinione utilizzare oggi come oggi l'amalgama sia piuttosto anacronistico e sconveniente, ma per ragioni squisitamente pratiche... chi le vuole "le piombature nere" adesso? Per non parlare dell'effetto galvanico di un metallo in soluzione salivare, l'espansione volumetrica, e soprattutto a durezza superficiale molto superiore a quella dello smalto che invece è mimata meglio dal composito. Comunque andiamo a braccetto per quanto riguarda il criticare l'atteggiamento demonizzatore nei confronti del mercurio, e il voler sputare veleno su quello che è stato un ottimo materiale (in alcuni casi, l'unico) per un lungo periodo dell'odontoiatria... poi il progresso ha fatto il suo corso, certo, ma tanto di cappello all'amalgama. Soprattutto, trovo vergognoso come su wikipedia italiana venga dato spazio a intere affermazioni per cui non esiste alcuna fonte. "E' stato dimostrato", "famosi scienziati dicono" ecc ecc sono frasi che ormai vanno bene solo per i racconti che ti fa la vicina di casa... se vuoi che ti diamo retta inserisci il riferimento all'articolo x pubblicato dalla rivista y che abbia un minimo di autorevolezza nella letteratura scientifica, o non scrivere affatto. Mi accingo a cancellare le frasi che non contengono alcuna citazione, ma sono convinto che qualcuno annullerà la modifica. --Ephestione (msg) 10:08, 17 nov 2008 (CET)

• Bravo Ephestione; sono un collega odontoiatria meno giovane di te, ma che non ne può più di vedere gli studi scientifici seri presi a schiaffi dal sensazionalismo. Io uso sia compositi che amalgama, a seconda che mi sembri più indicato l' uso dell' uno o dell' altro, pensando alla salute del paziente e basandomi sulla ricerca scientifica. Ai pazienti spaventati dalla campagna anti amalgama consiglio di rassicurarsi andando a vedere questo collegamento al sito della American Dental Association[[1] che, senza offesa e senza polemica, su queste cose la sa un po' più lunga di chi ha scritto questa pagina.

Aggiungo a quanto sopra che l'amalgama non è una MISCELA (quella si metteva nel serbatoio della Lambretta) ma una LEGA e che sui denti si effettuano RICOSTRUZIONI ed OTTURAZIONI ma non PIOMBATURE (prerogativa degli stagnari del secolo XVIII). --Marebcommons (msg) 19:58, 28 mar 2012 (CEST) Nel frattempo, dopo 6 anni, il link di cui sopra non c'è più: consoliamoci con quest'articolo fresco di stampa: http://www.ncbi.nlm.nih.gov/pubmed/26590663 --Marebcommons (msg) 18:28, 30 nov 2015 (CET)

Studi scientifici

Non riesco a capire come si possa seriamente sostenere che non esistono studi scientifici sull'amalgama quando ce ne sono circa 4.800..Per quanto riguarda l'autorevolezza di chi li ha scritti, a titolo di curiosità, chi è chiamato a giudicare, voi? Li avete letti tutti? Ne richiamo qualcuno:
