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

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
Clinical study to evaluate the factors involved in the evolution of the halitosis in a group of students
Halitoza este o problemă medico-socială universală, în toate comunităţile şi se referă la mirosul neplăcut care se emană din cavitatea orală. Obiectivele acestui studiu sunt: de a investiga prevalenţa halitozei evaluându-se prin
mijloace clinice, paraclinice şi printr-un screening tip anchetă a prezenţei
halitozei, a factorilor cauzali implicaţi: patologia cavităţii orale asociate, cum
ar fi cariile dentare şi boala parodontală, practicile de igienă orală, şi bolile
generale implicate, în rândul unui eşantion de studenţi de la Facultatea de
Medicină Dentară UMF Gr.T. Popa. Analiza rezultatelor obţinute cu stabilitatea corespondenţei dintre percepţia propriei halitoze şi a măsurilor de

The Role and Importance of the Caries Detectors Dyes in Early Diagnosis and Treatment of Dental Caries
Despite the progresses of the modern dentistry, the carious disease is still affecting a large number of peoples. The caries detectors would be helpful for diagnosis of early enamel caries as well as dentinal caries. The study focused on the role of caries detectors on objective criteria of assessment of the caries preparation, the early diagnosis of the incipient caries as well as monitorisation of the remineralising processes. The study used product Color-test of the Vladmiva (Rusia): solution and gel. The study was performed on 25 patients age 15-38 with medium and high level of cariogenic status. The statistical results show the practical importance of the caries detectors for the conservative treatment of the dental caries, with different degree of penetration in dental tissues. It also allows the monitorisation of the success of the non-invasive or minimal invasive treatment. The use of the caries detectors allows minimal preparation of the dental issues, accordingly to modern principles of the actual dentistry
Longitudinal Study Regarding Clinical Behaviour Of Glassionomer Type Sealers
The aim of this study was to assess, on a 3-years interval time (6, 12, 24, 36 months), the retention degree of some glass-ionomer type sealers, as well as their clinical efficiency. The research was performed on a 15 patients study group, with age between 8-16 years. A number of 42 sealings were performed using two sealing products: Fuji TRIAGE (GC, Leuven, Belgium) and Ketac Molar (3M ESPE, Seefeld, Germany). The sealing materials were applied using ART technique. The sealings were analysed at 6, 12, 24, 36 months. The study also assessed the frequency rate of new occlusal dental caries and the evolution stage of old dental caries. After 6 months, 88.1% of sealings were unaffected and 11.9% partially present. After 18 months, only 57.2% of sealings were unaffected, while 42.8% were partially present. After 24 months, 54.7% of sealings were partially present and 9.5% were absolutely absent. After 36 months, 35.7% of sealings were partially present, while 33.3% were absent. In all sealed surfaces was not recorded any new dental caries. For surfaces diagnosed with non-cavitary dental caries, were recorded after 18 months one new dentinal carious lesion, after 24 months two new dentinal carious lesions and after 36 month three new dentinal carious lesions. The results obtained in this study sustain and recommend the use of high viscosity glass-ionomer sealers for the sealing of occlusal surfaces. The results regarding clinical efficiency of glass-ionomer sealers showed that best results are obtained in the first 12 months, comparing with time intervals of 24 months and 36 months
Study Regarding the Assessment of Enamel Microhardness in Incipient Carious Lesions Treated by Icon Method
Sealing or infiltrating dental hard tissues are modern methods in conservative treatment of early carious lesions. One of the most actual methods for the conservative therapy of incipient dental caries is based on local use of sealing and infiltrating agents. This study assesses the enamel microhardness comparing artificial carious lesions treated by ICON method and carious lesions treated by fluorisation with microhardness of similar untreated surfaces. The highest values of microhardness were obtained for enamel demineralised surfaces treated with ICON. The ICON method conducts to the formation of harder enamel surfaces, able to resist to further acid attacks
