Os avan os nas ci ncias dos materiais e na medicina dent ria adesiva, juntamente com a crescente procura dos pacientes por restaura es com a cor dos dentes, tornaram a resina composta dent ria o material de elei o para a restaura o de les es cariosas. A vasta gama de viscosidades, cores, tonalidades, translucidez, opacidades, fluoresc ncia, etc., dispon vel com a atual gera o de resinas compostas, permitiu ao cl nico fornecer uma restaura o que imita a estrutura natural do dente e optimiza tamb m a fun o.

Die Fortschritte in der Materialwissenschaft und der adh siven Zahnheilkunde sowie die steigende Nachfrage der Patienten nach zahnfarbenen Restaurationen haben dazu gef hrt, dass Kompositharz das Material der Wahl f r die Restauration kari ser L sionen geworden ist. Die breite Palette an Viskosit ten, Farben, Schattierungen, Transluzenzen, Opazit ten, Fluoreszenzen usw., die mit der heutigen Generation von Kompositkunststoffen zur Verf gung steht, hat es dem Kliniker erm glicht, eine Restauration zu schaffen, die die nat rliche Zahnstruktur nachahmt und auch die Funktion optimiert.

I progressi della scienza dei materiali e dell'odontoiatria adesiva, insieme alla crescente richiesta di restauri colorati da parte dei pazienti, hanno reso la resina dentale composita il materiale preferito per il restauro delle lesioni cariose. L'ampia gamma di viscosit , colori, tonalit , traslucenze, opacit , fluorescenza, ecc. disponibile con l'attuale generazione di resine composite ha permesso al clinico di fornire un restauro che imita la struttura dentale naturale e ottimizza anche la funzione.

Les progr s r alis s dans le domaine de la science des mat riaux et de la dentisterie adh sive, ainsi que la demande croissante des patients pour des restaurations de couleur dentaire, ont fait de la r sine composite dentaire le mat riau de choix pour la restauration des l sions carieuses. La large gamme de viscosit s, de couleurs, de teintes, de translucidit s, d'opacit s, de fluorescences, etc., disponible avec la g n ration actuelle de r sines composites a permis au clinicien de fournir une restauration qui imite la structure naturelle de la dent et optimise galement la fonction.

Medical and dental science continually evolve, with research shaping tomorrow's realities. In dentistry, myths and realities persist, especially concerning pulp lesions and endodontic treatments. While trial-and-error once guided methodologies, recent decades have seen a shift towards scientific support. However, leading endodontic journals primarily focus on technical aspects rather than disease processes. This imbalance has hindered the advancement of biologically based knowledge in clinical endodontics. Dentists often excel technically but lack biological awareness, perpetuating a schism between clinicians and basic scientists. Despite modest progress, much of the accumulated biological knowledge has yet to find widespread clinical application. Consequently, conflicting views on managing endodontic disorders persist. This book reviews and examines the background of some of the more significant issues that have been debated in the endodontic field in recent years and discusses controversies regarding the clinical management of the disease processes associated with the vital and the non-vital dental pulp.

Dental composite resins have advanced tremendously to become the most preferred material for direct restorations in both anterior and posterior teeth. The advances in material sciences and adhesive dentistry along with the increasing patient demand for tooth-colored restorations have made dental composite resin the material of choice for restoration of carious lesions. The wide range of viscosities, colors, shades, translucencies, opacities, fluorescence, etc., available with the present generation of composite resins has enabled the clinician to provide a restoration that mimics natural tooth structure and optimizes function as well.

Os cimentos dent rios s o materiais que se fixam intra-oralmente e que s o comumente usados para unir um dente e a pr tese.1 Na literatura, a principal fun o de um cimento dent rio preencher o espa o entre o material restaurador e o preparo do dente, bem como aumentar a resist ncia ao deslocamento da restaura o durante a fun o. O sucesso a longo prazo de uma restaura o depende muito da sele o e da manipula o adequadas dos cimentos dent rios. Descobriu-se que a perda de reten o uma das causas mais comuns de falha da restaura o.

Les ciments dentaires sont des mat riaux prise intra-orale couramment utilis s pour assembler une dent et la proth se.1 Dans la litt rature, la fonction premi re d'un ciment dentaire est de combler l'espace entre le mat riau de restauration et la pr paration de la dent, ainsi que d'am liorer la r sistance au d logement de la restauration au cours de la fonction. Le succ s long terme d'une restauration d pend fortement du choix et de la manipulation appropri s des ciments dentaires. La perte de r tention est l'une des causes les plus fr quentes d' chec des restaurations.

Zahnzemente sind Materialien, die intraoral aush rten und blicherweise zum Verbinden von Zahn und Prothese verwendet werden.1 In der Literatur wird die prim re Funktion eines Zahnzements darin gesehen, den Raum zwischen Restaurationsmaterial und Zahnpr paration zu f llen und den Widerstand gegen eine Verschiebung der Restauration w hrend der Funktion zu erh hen. Der Langzeiterfolg einer Restauration h ngt in hohem Ma e von der richtigen Auswahl und Handhabung von Dentalzementen ab. Ein Retentionsverlust ist eine der h ufigsten Ursachen f r das Scheitern von Restaurationen.

I cementi dentali sono materiali che si fissano per via intraorale e che vengono comunemente utilizzati per unire un dente e la protesi.1 In letteratura, la funzione principale di un cemento dentale quella di riempire lo spazio tra il materiale da restauro e la preparazione del dente, nonch di aumentare la resistenza allo scollamento del restauro durante la funzione. Il successo a lungo termine di un restauro dipende fortemente dalla corretta selezione e manipolazione dei cementi dentali. La perdita di ritenzione una delle cause pi comuni di fallimento del restauro.
