AUTOMATIC SYSTEM FOR ADVANCED SPEED CONTROL OF THE DRILLING HOE

Drilling consists of the operation of creating a well, which involves a complex set of activities. In a narrower sense, it includes the dislocation of rocks and the extraction of rock fragments to the surface. A drilling tool called a bit is used to dislodge rocks, being connected to the surface drilling rig via a drill string. Automating the processes associated to drilling is extremely important to ensure its development in optimal conditions. This work is focused on the control of the drilling hoe rotation speed, in order to damage it as little as possible

Deep remineralization method used in initial caries lesions treatment

Summary In the clinical study were evaluated 30 pacientes having 72 initial caries lesions who were splited in 3 groups (first group included pacientes with lesions treated using deep remineralization method, the second group pacientes having lesions treated using clasical fluorization and the third group pacientes who did not received any treatment for the caries lesions). The results have demonstrated higher efficiency of deep fluorization method when compare with the clasical fluorization. Good effects of this therapy were obtained both in depth and in width of the caries lesions. An important advantage of this method consisted in a long time remineralization and a deep remineralization of the caries defect.Rezumat Cercetările clinice realizate pe 30 pacienţi, respectiv 86 leziuni carioase incipiente repartizate pe 3 loturi (lot 1 tratament prin remineralizare profundă, lot 2 tratament prin fluorizare clasică, lot 3-Martor, care nu a fost supus nici unui tratament de fluorizare, decât că au fost aplicate măsuri de îndepărtare a factorilor etiologici). S-a demonstrat eficacitatea net superioară a metodei de remineralizare profundă instituită în leziunile carioase incipiente, obţinându-se astfel un efect terapeutic mai bun atât în profunzime cât şi în suprafaţa acestuia. Un alt avantaj major este obţinerea unui efect remineralizant de mai lungă durată şi o remineralizare a focarului până în profunzimea defectului

Approximal incipient dental caries — early diagnostic and noninvasive therapeutic approaches

Rezumat Leziunile carioase incipiente cu localizare pe feţele aproximale sunt de cele mai multe ori imposibil de diagnosticat în cadrul unui simplu examen clinic. De cele mai multe ori ele atrag atenţia practicianului stomatolog doar atunci când evoluţia acestora este amplă atât în smalţ cât şi în dentină. Scopul acestui studiu este de a evalua posibilităţile unui diagnostic precoce a leziunilor carioase incipiente de pe feţele aproximale şi a eficienţei tratamentului prin instituirea unei terapii de remineralizare prin aplicarea unor membrane biodegradabile cu eliberare lentă a fluorului. Posibilitatea membranelor de a asigura o acţiune de durată şi un aport remanent al fluorului în timp asigură un efect carioprofilactic şi terapeutic mai eficient în comparaţie cu alte metode de fluorizare locală. Efectul principal carioprofilactic şi de remineralizare a ţesuturilor demineralizate este datorat fluorurii de sodiu care se eliberează treptat, fapt ce permite declanşarea proceselor de remineralizare cu diminuarea şi chiar dispariţia focarului de demineralizare.Summary The diagnostic of the approximal incipient dental caries is difficult within clinical examen. Often these dental caries are diagnosed only in advanced stages. The aim of this study is to assess the possibilities of early diagnosis of the approximal dental caries and the efficiency of the remineralisation treatment based on biodegrading membranes with fluor slow release. The study shows that long term action of the fluor membranes assures a more efficient caries preventive and therapeutic effect. This remineralisation effect is due to slow release of natrium fluoride that diminishes surface and depth of the demineralisation areas

The assessment of bacterial film cariogenic potential changes following the action of remineralisation agents

Rezumat. Unul dintre factorii etiologici chee, care joaca un rol important în dezvoltarea cariei dentare şi a afecţiunilor parodontale este microflora biofilmului bacterian. Scopul acestui studiu este de a evalua acţiunea unor preparate de remineralizare asupra cariogenităţii biofilmului bacterian. Material si metodă: s-a utilizat in evaluarea cariogenitatii biofilmului bacterian testul Hardwick J.L., Manly E.B. înainte şi după aplicarea preparatelor de remineralizare pe bază de calciu, fosfat şi fluor. Rezultate. Se constată o îmbunătăţire a situaţiei cariogene din cavitatea orală sub acţiunea acestor preparate. Deşi nu este o diferenţă semnificativă d.p.d.v. statistic, un efect mai favorabil îl au preparatele ce conţin calciu, fosfat şi fluor, comparativ cu cele ce conţin doar calciu şi fosfat.Summary. The bacterial film is a key ethiological factor with a major role in dental caries and periodontal diseases development and evolution. Aim. The aim of this study is to assess the action of some remineralisation products over the cariogenic action of bacterial biofilm. Materials and method. The cariogenical potential bacterial biofilm test Hardwick J.L.&Manly E.B. was performed before and after the application of remineralisation products with calcium, phosphat and fluor. Results. The results show an improvement of cariogenic situation after the action of remineralisation agents. The products that contain calcium, phosphat and fluor have a more efficient action comparing with products based only on calcium and phosphat

Study regardind the early carious lesion treatment using ICON method

Rezumat: Una din metodele cele mai actuale şi de perspectivă ale orientării terapiei conservatoare în caria incipientă este metoda utilizării locale a unor preparate de sigilare şi respectiv de infiltrare a ţesuturilor dure dentare. Abordarea temei alese, a fost determinată de necesitatea unei înţelegeri cât mai corecte a importanţei unui diagnostic cât mai precoce, corect şi precis al leziunilor carioase incipiente asociate tratamentelor ortodontice, a particularităţilor acestora în ceea ce priveşte apariţia, evoluţia, diagnosticul, cât şi a posibilităţilor terapeutice ce pot fi instituite în acest caz. Studiul a fost efectuat pe un lot de pacienţi cu vârste cuprinse între 10 şi 35 ani, evaluându-se comparativ eficienţa terapiei lezunilor carioase asociate tratamentului ortodontic fix prin metoda de infiltrare ICON comparativ cu metoda de remineralizare profundă. În urma analizei rezultatelor obţinute în cadrul acestei cercetări putem concluziona că ambele metode alese în tratamentul leziunilor carioase incipiente asociate tratamentului odontic fix sunt eficiente în oprirea evoluţiei proceselor carioase incipiente. Metoda infiltrării ICON oferă în schimb rezultate estetice superioare.Summary: Sealing or infiltrating dental hard tissues are modern methods in conservative treatment of early carious lesions. An early and precise diagnostic of incipient carious lesion associated with orthodontical treatment is very important in order to establish therapeutical procedures. In this context, the theme of our study is one of great interest. The study group was represented by patients of 10-35 years old. We used ICON method and deep remineralisation method in the treatment of carious lesions associated with orthodontical treatment. The results showed the efficiency of both methods in arresting carious evolution. The ICON method has a real advantage from the point of vue of the aesthetic result
