The primary aim of this study was to demonstrate that periodontal ultrasonography is a reliable method with which identify and evaluate the attachment level gingival junctional epithelium. A secondary devise an automated computer-assisted allows examiner more easily sulcus contour on ultrasound images.This in vitro carried out 36 sites lingual surface eight pig mandibles. For each site, performed by same examiner, using DermaScan C Cortex Technology (Denmark) 20-MHz transducer. Subsequently,...

The present research is focused on three different classes of orthodontic cements: resin composites (e.g., BracePaste); resin-modified glass ionomer RMGIC Fuji Ortho) and cement Transbond). Their mechanical properties such as compressive strength, diametral tensile strength flexural were correlated with the samples' microstructures, liquid absorption, solubility in liquid. results show that best (100 MPa) (75 Mpa) was obtained by BracePaste Transbond (230 MPa). lowestvalues Ortho RMGIC....

The study aimed to assess self-reported symptoms of periodontal disease (gingival bleeding, tooth mobility and halitosis) among diabetic non-diabetic patients from Transylvania, Romania. Using statistical analysis methods, correlation between the aforementioned diet, oral hygiene habits, stress, physical activity, BMI (body mass index) were researched. Another secondary objective was impact health, aesthetics, halitosis on their life. Patients' willingness use a mobile app for generating...

The geometry of some medical images tissues, obtained by elastography and ultrasonography, is characterized in terms complexity parameters such as the fractal dimension (FD). It well known that any image there are very subtle details not easily detectable human eye. However, many cases like imaging diagnosis, these important since they might contain hidden information about possible existence certain pathological lesions tissue degeneration, inflammation, or tumors. Therefore, an automatic...

We aim to define the values of shear wave velocity (SWV) in normal parotid glands (PG) and identify modifications tissue stiffness patients with irradiated nasopharyngeal carcinoma.Sixty pertaining 30 healthy volunteers 40 pathological 20 who had underwent radiation therapy for carcinoma were included this study. The a B mode ultrasonography examination volume gland was determined. A subsequent Acoustic Radiation Forde Impulse Imaging (ARFI) performed SWV determined central periphery...

The use of sugar by dental plaque microorganisms leads to acid formation from the bacteria metabolism, which determines a decrease pH onto teeth surfaces. value critical is 5.2-5.5. We aimed evaluate capacity patients change their diet towards caries prevention after acknowledging values saliva parameters (pH, buffer capacity).A group 52 subjects were clinically examined according International Caries Assessment and Detection System protocol. They required complete questionnaire salivary...

Background and Objectives: Dental caries is a preventable, reversible disease in its early stages. This study evaluated the intra-rater agreement of International Caries Assessment Detection System (ICDAS) scores with Medit i500® Omnicam® scanners versus traditional clinical examinations inter-rater using among senior dentists dental students between these two groups. Materials Methods: A total 24 patients aged 21 34 years, randomly selected from interns, underwent four (three intraoral...

Background and objectives. The aim of the study was to identify in literature potential causes overtreatment dentistry, most frequent types overtreatments recommendations how avoid those issues. Materials methods. A search carried out PubMed/Medline, Web Science ScienceDirect databases. used following keywords: “overtreatment” “dentistry” for papers published English until June 2022. Results. 211 results were found PubMed, 122 523 ScienceDirect. duplicates, titles abstracts that not related...

Background and aims. “Severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2) is the name of etiological agent pandemic Corona Virus Disease (COVID-19) which was declared on March 11, 2020 by WHO affected all countries world, including Romania. Our study aimed to evaluate psycho-affective implications economic consequences for dentists in Romania during COVID-19 (Corona Disease) state emergency their opinion patients’ oral health impact. Methods. A cross-sectional observational...

Background: Adhesion within endodontic obturation material and root canal walls improves the efficacy of treatment by establishing a barrier that inhibits reinfection entombs residual bacteria. This study evaluates push-out bond strength (POBS) calcium silicate sealers compared to an epoxy-resin-based sealer. Methods: A total 36 extracted mono-radicular teeth were prepared with Pro Taper Ultimate irrigated 5.25% sodium hypochlorite 17% EDTA. The specimens randomly split into three groups (n...
