The usage of vector machine in treatment of marginal chronic periodontitis
Rezumat.
Aparatul Vector reprezintă o nouă generaţie a aparatelor ultrasonice,
destinată tratamentului minimal invaziv al afecţiunilor inflamatorii ale pa‑
rodontului. Pentru a determina eficacitatea acestuia am recurs la un studiu
clinic ce a avut la bază examinarea şi tratamentul unui lot de 10 pacienţi
(7 bărbaţi şi 3 femei). Pacienţii implicaţi erau diagnosticaţi cu parodontită
marginală cronică forma: uşoară, medie şi gravă şi au fost repartizaţi în 2
grupe cîte 5 persoane.Summary.
Vector System is a newly developed ultrasonic device for minimally in‑
vasive periodontal therapy. The efficacy of the Vector ultrasonic system was
determined in a clinical study which included 10 patients (7 men and 3 wo‑
men) with moderate to advanced chronical periodontal disease and were
sorted into two groups of 5

Using SONICretro tips in surgical endodontic treatment
Rezumat
Introducerea microinstrumentelor în chirurgia endodontică a dus la
îmbunătăţirea tehnicilor chirurgicale şi a rezultatelor clinice. Studiul a avut
ca scop evaluarea rezultatelor în urma utilizării anselor noi SONICretro
pentru prepararea cavităţii retrograde. Au fost selectaţi consecutiv 10 pacienţi care au fost supuşi rezecţiei apicale. Cavitatea retrogradă a fost preparată cu ajutorul anselor diamantate activate sonic şi obturată cu ProRoot
MTA. Evaluarea rezultatelor la 6 luni de la intervenţie au demonstrat că
ansele SONICretro sunt ideale pentru prepararea cavităţii retrograde. Ele
simplifică accesul la vîrful radicular, prepară o cavitate retentivă, iar rezultatele clinice sunt excelente.Summary
The introduction of microinstruments has clearly improved the surgical
technique in periradicular surgery with apicectomy. Purpose of this study
was to evaluate the outcome of periradicular surgery using a new set of
SONICretro tips. Ten patients who had 10 consecutively treated teeth with
periradicular pathology were enrolled in this study. Root-end cavity preparation was performed using diamond-surfaced retrotips driven by a sonic
handpiece and ProRootMTA was used as the filling material. At the 6-months follow-up results showed that new retrotips were found to be ideal for
root-end cavity preparation. They simplify the surgical approach to root
ends, preparing retentive cavity, gives excellent results
Treatment of dental abrasion caused by bruxism, using direct restauration method
Catedra stomatologie terapeutica FECMF USMF „Nicolae Testemiţanu”In contemporary dentistry dental abrasion is a common problem encountered, as in most
cases caused by bruxism. In the study were taken seven people aged between 26 and 40 years
diagnosed with dental abrasion passing (M.Buşan) the enamel-dentin border as a result of
bruxism, being examined clinically and paraclinically. As a result of the direct restoration guided
with the reorganization of the occlusion, we found that the tooth abrasion can be treated
successfully with good minimally invasive method, which implies preservation of healthy dental
tissue within a long time.
În stomatologia contemporană abraziunea dentară este o problemă frecvent întîlnită,
fiind, în majoritatea cazurilor, provocată de bruxism. În studiu au fost luate 7 persoane cu vîrsta
cuprinsă între 26 şi 40 ani, diagnosticaţi cu abraziune dentară de trecere(M.Buşan), (pînă la
joncţiunea smalţ – dentină) ca urmare a bruxismului, fiind examinaţi clinic şi paraclinic. În urma
tratamentului prin metoda restaurării directe dirijate cu reorganizarea ocluziei am concluzionat
că abraziunea dentară poate fi tratată cu succes prin metoda miniinvazivă care subînţelege
păstrarea la maxim a ţesuturilor dentare sănătoase pe un timp îndelungat
New evidence on the pecking order hypothesis: The case of French convertible bonds
Abstract Convertible bonds (CBs) are an important asset class but their analysis in function of the equity and bond components has received insufficient attention in France. This study investigates the relation between announcement effects and equity components for 141 French CB issues. We use the CB sensitivity to its underlying common stock as a proxy for the equity component. Our results indicate that CB issue announcements imply significantly negative market responses, which are negatively related to the equity component. This result supports the Myers and Majluf (1984) model [Myers, S.C., Majluf, N.S., 1984. Corporate financing and investment decisions when firms have information that investors do not have. J. Financial Econ. 13,. A more detailed analysis reveals that the market reaction is significantly positive for the subset of 'mixed' CBs. Mixed CB issuers are characterized by high informational asymmetries about investment opportunities compared with informational asymmetries about assets-in-place. This finding supports the revised Myers and Majluf model, which predicts positive announcement effects under certain conditions
