    Evaluating the effects of different remineralization agents on initial enamel lesions in vitro

    Aim: Disruption of the demineralization–remineralization balance could activate the development of initial enamel lesions. Extrinsic assistance is needed to remineralize enamel lesions. The aim of this study was to evaluate the efects of fuoride varnish, enamel matrix proteins derivative, and experimental bioactive glass (BAG) on remineralization of initial enamel lesions in vitro. Materials and Methods: Artifcial initial caries lesions were developed on ffty human enamel samples using demineralization solution (pH 4.5, 37°C, 96 hours). Samples were randomly assigned to 5 groups (n=10): I-Fluoride varnish (Enamelast), II-Experimental BAG + 37% phosphoric acid (PA), III-Enamel matrix proteins derivative (EMPD, Emdogain) +Ethylenediamine-Tetraacetic-Acid (EDTA), IVEMPD+37% PA, V-Control (untreated). All remineralization agents were applied with pH cycling for 7 days. The samples were scanned by optical coherence tomography (OCT) at baseline, demineralization, and after pH cycling. Lesion depths were measured using image analysis software (ImageJ). Lesions were evaluated using surface microhardness (SMH) and two fuorescence methods (FluoreCam® and DIAGNOdent Pen (DDPen)). The data were statistically analyzed by Kruskal Wallis, Friedman, and Wilcoxon tests (p<0.05). Results: According to OCT results, fuoride varnish was found to be the most efective agent in reducing lesion depth (p=0.005). Depending on SMH results, all agents increased the surface hardness values after pH cycling. No signifcant diference was found among fuoride varnish, BAG, and EMPD+PA groups. And these microhardness values were signifcantly higher than EMPD+EDTA and control groups (p<0.001). According to the DDPen score criteria, all groups showed lower scores compared with the control group (p<0.001), however, Clinical Oral Investigations (2022) 26:7299–7348 7317 1 3 no signifcant diference was found among the remineralization agent groups. In FluoreCam assessment, size and intensity values of all treated groups showed improvement. However, there was no signifcant diference between the treatment groups in terms of FluoreCam-size measurements (p=0.186). Conclusion: BAG and EMPD+PA has a remineralization capacity as much as fuoride varnish. EMPD+PA showed better microhardness and lesion intensity results than EMPD+EDTA.

    Assessment of Different Imaging Systems for Dental Plaque Scoring: an in-vivo study
    (2022-06-13) MEŞELİ, SİMGE; EKENEL, SERGEN; AKSU, MEHMET BURAK; YANIKOĞLU, FUNDA; TAĞTEKİN, DİLEK; MEŞELİ S., EKENEL S., AKSU M. B., TAĞTEKİN D., YANIKOĞLU F.
    Aim: The aim of the clinical study was to analyze the correlation between the dental plaque scores measuredby different imaging systems.Materials and Methods: Thirty volunteers between the age of 18-30, who visited Marmara University, Facultyof Dentistry whose DMFT scores were under 4, were included in the study. Dental plaque on anterior teeth’sbuccal surfaces of the volunteers were scored using different imaging systems after staining with a disclosinggel. The patients were divided into three groups. The groups were given two different herbal toothpastes(ginger and hemp) and a conventional toothpaste. Digital photography, intraoral digital scanning (iTeroElements 2) and FluoreCam were used for taking intraoral images. The Turesky Modified Quigley Hein PlaqueIndex (TMQHPI) was used for the clinical examination and the taken images. The correlations between theclinical examination and imaging scores were analyzed before and after using the toothpastes for 21 days.Shapiro Wilk Test and Pearson’s correlation were performed using IBM SPSS Statistics V23 (IBM Co. , Armonk,USA) (p<0.05).Results: The lowest mean value was obtained in the clinical examination without disclosing gel method andthe highest mean value was obtained in the FluoreCam method. The mean value of the clinical examinationwithout disclosing gel was found to be lower than the clinical examination with disclosing gel method andintraoral digital scanning method. There was no significant difference between toothpastes before and aftertoothbrushing for all clinical imaging methods.Conclusion: Staining of the plaque and the use of digital imaging systems have shown a positive effect inthe determination of dental plaque. Intraoral imaging systems may be used as an alternative to supplementthe shortcomings of conventional clinical indices for educating patients about plaque control and continuedpatient oral care. Herbal toothpastes are just as effective as conventional toothpastes in removing dentalplaque.
