CONTRIBUTIONS ON THE ULTRASOUND USE IN FASTFINDING AND CREATING THE ACCES TO THE CALCIFIED CANNALS AND ABLATION OF THE PULPOLITES

In the treatment with ultrasounds, two categories of devices are used, which work on theprinciple of the magnetostriction phenomenon or the principle of pieso-electrictricity. The mostimportant part of an endodontic ultrasound device is the ultra-acoustic system which must becalculated, projected and made in such way so th exercise a certain type of ultrasound (asked bythat application) which together with the endodontic instrument acoustically activated to worktogether in resonance regime. In order to find the hidden canals calcified and for an easiermaking of the acces to the root canals is suggested an endodontic instrument with an activespecific part and with a central canal which allows the penetration of a cooling fluid in the workarea and in order to create the phenomenon of ultrasound cavit

Dental practice in digital era: quo vadimus?

Rezumat. Graţie progresului tehnologic înregistrat în ultimii ani sistemele CAD/ CAM reprezintă o certitudine practică a utilizării lor în restaurările dentare. Prin intermediul unui scaner intraoral performant în prezent există posibilitatea expedierii rapide pe cale electronică în laboratorul de tehnică dentară a unei amprente digitale de acurateţe efectuate direct în cabinet de către medic. Fluxul tehnologic digital concretizează realitatea virtuală, care debutează prin amprentarea optică a câmpului protetic în cabinet, se continuă prin utilizarea articulatoarelor virtuale și efectuarea designului 3D al reconstituirii protetice și se termină în final cu confecţionarea unei lucrări protetice reale, prin frezare sau procese de adiţie dirijate de un software dedicat. Pentru moment introducerea tehnologiei digitale ca procedură habituală de confecţionare a unei restaurări protetice este totuși grevată atât de necesitatea instruirii unui personal cu înaltă calificare profesională cât și de reducerea preţurilor de cost, deocamdată încă mult prea ridicate comparativ cu procedeele convenţionale de tehnică dentară.Summary. Due to the technological progress of last years CAD/CAM systems definitely proved to be extremely useful in tooth restorations. Using an updated intraoral scanner nowadays is possible to quickly send by e–mail to dental laboratory an accurate digital impression directly recorded in dental office by the practitioner. The digital technological flow materializes the virtual reality which begins at dental chair with optic impression of prosthetic field, goes farther by using the virtual articulators and drawing up the 3D design of prosthetic restoration, and arrives at the end–point by manufacturing the real prosthetic product, either by milling or addition process, under the control of dedicated software. However, for the time being the use of digital technology as habitual procedure to manufacturing a prosthetic restoration sets hurdles since it needs both personnel of high professional qualification and reduced costs which presently are higher as compared to conventional procedures performed in common dental laboratories

GSK-3 Inhibitors and Tooth Repair: An Ethical Analysis

Tideglusib®, a GSK-3 inhibitor, was initially tested for the treatment of Alzheimer’s disease. However, a recent report has suggested its potential off-label use for the treatment of dental cavities. Even if this effect is not yet confirmed, this off-label use can have significant public/dental health consequences, mainly because of the large number of patients with cavities. The purpose of this mini-review is to perform an ethical analysis of the use of Tideglusib in dentistry. The ethical analysis identified three main areas in which ethical breaches could be significant: 1) respect for the autonomy of the patient, 2) issues raised by horizontal shifts in the translational research process, and 3) the conflict between dental beneficence and general non-maleficence. In conclusion, the use of Tideglusib in dentistry should respect the same strict ethical and regulatory criteria from clinical medicine. A translation of the potential risks should be done only after large-scale, phase-III/IV clinical trials, explicitly designed to test the usefulness of this drug in dental medicine

MODERN METHODS OF CORONO-RADICULAR RESTORATION OF A LATERAL TOOTH WITH AN ENDODONTIC TREATMENT

Most of the teeth that require endodontic treatment have been affected by extensive caries. These weakened them, increasing their risk of fracture and making their restoration much more difficult for the dento-maxillary function to restore. Modern dentistry offers various possibilities for restoring endodontically treated teeth. The best option is selected by the clinician according to the clinical case particularities. This article is a summary of the modern methods used for restoring a lateral tooth with an endodontic treatment

Management of a flare up case after endodontic treatment procedure

A flare-up is defined as a pain and/or swelling of the soft tissues that occurs within a few hous or a few days following the root canal treatment. In some cases, the flare-ups can apear after the finishing of the root canal treatment, due to the penetration or development of the microorganisms into the root canal. The pain felt by the patient depends on the extent of the periradicular tissue injury, its severity and intensity of the inflammatory imune response. The article discusses the microbial irritation of apical periodontal tissue caused by insufficient instrumentation and filling of the root canals, factors that lead to failure of the outcome of root canals treatment

Endosequence BC Sealer as root canal filling in endodontic retreatment

Rezumat. Reluarea tratamentului endodontic constă în dezobturarea canalelor unui dinte deja tratat, refacererea tratamentului chemomecanic pe întreg canalul până la apex, tratament antispetic cu hidroxid de calciu și clorhexidină și refacerea corectă a obturaţiei de canal. Dezobturarea este etapa cea mai laborioasă din cauza durităţii unor cimenturi de sigilare care nu pot fi îndepărtate decât prin mijloace mecanice rotative, de unde și riscul de apariţie a unor iatrogenii care complică tratamentul. Se impune de asemenea o lărgire suplimentară a canalului cu 0,05-0,10 ISO pentru îndepărtarea mai eficientă a materialelor de obturaţie și biofilmelor de interfaţă de pe pereţii canalelor. Reobturarea canalelor radiculare presupune utilizarea gutapercii, prin diverse tehnici, simultan cu un ciment de sigilare biocompatibil, radioopac, cu contracţie de priză minimală, efect antibacterian și capacitatea de a se cupla adeziv la pereţii de dentină ai canalelor radiculare. EndoSequence® BC Sealer™ este un asemenea sigilant, de natură bioceramică, care în plus oferă posibilitatea formării unui monobloc adeziv cu dentina prin hidroxiapatita generată în cursul prizei în urma contactului cu lichidele tisulare.Summary. The endodontic canal retreatment lies in removal of root canal filling of previously treated tooth, an additional enlargement of root canal to its apical terminus, calcium hydroxide and chlorhexidine dressing and, the appropiate root canal filling. The removal of root canal filling is the most difficult step due to the hardness of sealares that need rotary instruments to be pushed out and sometimes may generate iatrogenies. An 0.5-0.10 ISO additional enlargement of root canal is also required for better cleaning of filling material remnants and biofilms that adhered on root canal walls. The root canal refill is based on gutta-percha core and sealer that ideally has to be biocompatible, radiopaque, with minimal setting shrinkage, antibacterial and strongly adhesive to dentinal tissue of root canal walls. EndoSequence® BC Sealer™ is such a bioceramic-based sealer that has the possibility to generate an adhesive monoblock with dentine because during setting is combined with tissue fluids resulting in an interface layer of hydroxyapatite

The causes of adhesive direct dental restorations failures

The modern dental caries adhesive direct restoration requires a working protocol that includes stages and techniques that must be strictly followed to ensure the correct morphological and functional reconstruction, as well as an increased longevity of the restoration and implicitly of the respective tooth in the oral cavity. Failures in achieving these goals are represented by the occurrence of recurrent caries, secondary or residual caries, coronary fractures, leading to pulpal and periodontal complications. They can be due to both incorrect therapeutic maneuvers and other causes, for which the dentist is not responsible, such as manufacturing defects of dental materials that are not visible during inspection or the patient's attitude towards oral hygiene

Case report of a rare bullous variant of oral lichen planus

The aim of this report is to describe the lichen planus on the oral mucosa in the bullous variant of the disease. It is often misdiagnosed with other mucosa disorders (allergies, bullous dermatosis). A 37-year-old-female patient presented for oral mucosa painful lesions of 3 months duration. A microscopic examination of the lesional areas was consistent with the diagnosis of oral lichen planus and direct immunofluorescence confirmed it. This case showed that although a rare condition the variant of bullous lichen planus can be encountered in daily clinical practice

Menopause and oral health

At menopause, a woman's body undergoes radical hormonal changes, which predisposes to damage of the oral cavity. The onset of menopause is a series of morpho functional physiological adaptive changes with systemic and oral action in women. Oral health is closely related to dental hygiene, a major concern in menopause. The addressability of women to dental services tends to increase due to perimenopausal changes that occur in the gums and teeth and the oral microbiome. These changes have a hormonal substrate that significantly influences the evolution of oral health. The purpose of this review is to understand the occurrence and evolution of oro-dental complications in menopause and the systematization of therapeutic regimens. The PubMed and Web Of Science databases searched identified approximately 21 eligible articles. Periodontal damage is the most common, followed by dryness and burning sensation in the mouth. The role of hormone replacement therapy is controversial in terms of prophylaxis or the obvious therapeutic aspect of menopausal women with oral symptoms. The lack of extensive research, at least for the time being, does not establish clear therapeutic protocols to resolve these dental conditions
