Efficiency of endodontic treatmentin the medication ofchronic destructive apical periodontitis

Rezumat Examenul clinic şi paraclinic (radiografie direcționată şi ortopantomografie) a 102 pacienţi (143 dinţi permanenţi) cu periodontită cronică osteo — distructivă a demonstrat că, AH plus utilizat în calitate de siller, administrat cu gutaperca fierbinte termoplastificată Gutta core utilizat în calitate de filler, este o metodă de obturare a canalelor radiculare net superioară, comparativ cu Endofill şi Endomethasone în calitate de siller, administrate cu conuri de gutapercă — filler, prin metoda de condensare laterală. Rezultatele au fost confirmate prin examinări clinice şi paraclinice repetate până la iniţierea tratamentului, la 3 luni, 6 luni şi după 12 luni din momentul finisării tratmentului endodontic.Summary Clinical and radiological examination (periapical view and panoramic film) of 102 patients (143 permanent teeth) with chronic destructive apical periodontitis proved that, AH plus used as a root canal sealer, administrated with thermo-plastified gutta-percha named Gutta Core used as filler, is the superior root canal obturation technique, compared to Endofill and Endomethasone as root canal sealers, administrated with gutta-percha fillers, in the lateral condensation technique. The results were confirmed by repetead clinical and radiological examinations from the start of the endodontic treatment, 3 months, 6 months, 12 months after the end of the endodontic treatment

The perspective therapy of chronic apical periodontitis in the immature permanent teeth

Catedra Stomatologie terapeutică FPMComparative study of 73 apical periodontitis cases of permanent teeth with unformed root treated with calcium hydroxid (32 pacients-35 teeth) and Bio-R (41 pacients-45 teeth) demonstrates that Bio-R preferentialy stimulates apexogenesis, but calcium hydroxid leads to apexifiation. The long-term treatment with calcium hydroxid, that leads to the brittlesness of the unformed and incompletly mineralized apex, concomitantly has been established. Studiul comparativ a 73 cazuri de periodontită apicală a dinţilor permanenţi cu rădăcina neformată trataţi cu hydroxd de calciu (32 pacienţi – 35 dinţi) şi cu Bio-R (41 pacienţi – 45 dinţi) a demonstrat că, „Bio-R”-ul stimulează preferenţial apexogeneza, pe când hydroxidul de calciu conduce la apexifiere. Concomitent s-a constatat că, tratamentul pe termen lung cu hydroxid de calciu conduce la fragilitatea apexului neformat, mineralizat incomplet

Rational treatment of radicular cyst

Rezumat. Au fost supuşi BioR-terapiei endodontice 54 de dinţi la 45 de pacienţi afectaţi de chist radicular. BioR a manifestat capacităţi majore de stimulare a neoosteogenezei reparative cu refacere osoasă totală în termen de până la 12 luni.Summary. Forty-five patients having 54 cyst-affected teeth received endodontic treatment with BioR. BioR manifested high stimulating capacities of reparative neoosteogenesis leading to a total bone recovery within up to 12 months

Cuneiform defects, teoretic and clinical aspects

Catedra Stomatologie Terapeutică FECMF, USMF „Nicolae Testemiţanu”Between the years 2005 and 2010 ninety-three patients have been examined, 31,5% being detected cuneiform defects of various degrees. Abfraction was the chief etiologic factor. The performed treatment was varied. În intervalul anilor 2005-2010 au fost examinaţi 93 de pacienţi din care la 31,50% au fost diagnosticate defecte cuneiforme de diferite grade. Ca factor etiologic de bază a servit abfracţia. Tratamentul executat a fost complex

The new facts in medication of the endodontic area

Rezumat. Studiul prezintă situaţia ştiinţifico-practică a folosirii remediilor antiseptice în endodonţia clinică la nivel interstatal si rezultatele obţinute de autori pe parcursul a 5 ani (2010—2015). În urma diagnosticării diferitor forme de pulpite şi periodontite apicale la 205 pacienţi şi tratamentului endodotic cu prelucrarea antiseptică a canalelor radiculare s-a demonstrat că cele mai simţitoare rezultate pozitive au prezentat hipocloridul de sodiu de 3% combinat cu clorhexidina 0,2%, sau soluţiei 15% EDTA urmată de apa oxigenată 3% sau Glyde.Summary. Scientific-practical study shows the use of antiseptics in endodontic clinic at interstate level and the results achieved by the practice over the last five years (2010—2015). After diagnosis of various forms of pulpitis and the apical periodontitis in 205 patients endodontic root canal treatment with antiseptics has shown that the most positive results came with the use of 3% sodium hypochlorite, with 0.2% Chlorhexidine or 15% EDTA (Edetic Acid), followed by 3% hydrogen peroxide or Glyde solution

Consideration about immunomodulator treatment of chronic apical periodontitis in the immature permanent teeth

Rezumat. Studiul comparativ a 73 cazuri de periodontită apicală a dinţilor permanenţi cu rădăcina neformată trataţi cu hydroxd de calciu (32 pacienţi – 35 dinţi) şi cu Bio-R (41 pacienţi – 45 dinţi) a demonstrat că, „Bio-R”-ul stimulează preferenţial apexogeneza (apexoregenerarea), pe când hydroxidul de calciu conduce la apexifiere. Concomitent s-a constatat că, tratamentul pe termen lung cu hydroxid de calciu conduce la fragilitatea apexului neformat, mineralizat incomplet.Summary. Comparative study of 73 apical periodontitis cases of permanent teeth with unformed root treated with calcium hydroxid (32 pacients-35 teeth) and Bio-R (41 pacients-45 teeth) demonstrates that Bio-R preferentialy stimulates apexogenesis (apexsoregeneration), but calcium hydroxid leads to apexifiation. The long-term treatment with calcium hydroxid, that leads to the brittleness of the unformed and incompletely mineralized apex, concomitantly has been established

Synthesis, Characterization, and Biological Properties of the Copper(II) Complexes with Novel Ligand: N-[4-({2-[1-(pyridin-2-yl)ethylidene]hydrazinecarbothioyl}amino)phenyl]acetamide

For the first time, a thiosemicarbazone-type ligand containing a paracetamol structural unit was synthesized. Five new coordination compounds based on copper(II) salts: [Cu(L)CH3COO] (1), [{Cu(L)Cl}2]·H2O (2), [Cu(L)H2O·DMF]NO3 (3), [Cu(L)Br] (4), [Cu(L)H2O]ClO4 (5), were obtained, where HL is N-[4-({2-[1-(pyridin-2-yl)ethylidene]hydrazinecarbothioyl}amino)phenyl]acetamide. The new HL was characterized by NMR, FTIR, spectroscopy, and X-ray crystallography. All copper(II) coordination compounds were characterized by elemental analysis, FTIR, EPR spectroscopy, and molar electrical conductivity. Furthermore, single crystal X-ray diffraction analysis elucidated the structures of thiosemicarbazone HL as well as complexes 1–3. All compounds were tested for antimicrobial, antifungal, and antioxidant activities, and their toxicity to Daphnia magna was studied. Biological evaluation has revealed that most of the synthesized compounds demonstrate promising antibacterial, antifungal, and antioxidant activities. In many cases, their antibacterial/antifungal activity is comparable to that of certain drugs used in medicine for these purposes, and in some cases, even surpasses them. HL and complexes 2–5 exhibit antioxidant activity that surpasses that of Trolox. Furthermore, HL and complex 2 display virtually no toxicity to D. magna
