RESUMO

Introduction: The successful restoration of damaged tissue requires a complicated, dynamic process called wound healing, which is supported by a wide range of cellular activities. Natural materials generated from medicinal plants have been identified, and their therapeutic potential evaluation has resulted in the development of novel, affordable medicines that can be used to treat a variety of illnesses, including chronic wounds, with limited side effects. Aims and Objectives: This study aimed to assess the wound-healing property of Glycyrrhiza Glabra (Athimathuram) plant extracts by using an in vitro scratch assay test, as well as to evaluate their cellular toxicity. Materials and Methods: Using the Soxhlet device, ethanolic extraction of the plant material was done, and the cytotoxicity of the extract on the Vero cell line was examined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. One of the most often utilized mammalian in vitro cell lines in research was Vero cells. To assess the wound healing properties of G. glabra plant extract, an in vitro scratch assay was used, and their potential mechanisms of action were examined. Results: Even at higher concentrations, the MTT assay showed that G. Glabra plant extracts had no cytotoxic effects on the cells. In vitro scratch assay showed that the healing process of the cell line was increased by 23.33% when compared with the controlled cell lines. Conclusion: Our research demonstrated that G. glabra has in vitro wound healing capabilities. As a result, G. glabra can be suggested as a possible source of compounds that treat wounds.

RESUMO

The main purpose of this bibliometric analysis is to conduct a quantitative and qualitative analysis of the publications on dental caries. Research productivity can be measured with the use of bibliometric analysis. In this study, we conducted a bibliometric analysis using the Scopus database to identify dental caries research trends and patterns over the years. The search yielded 1630 scientific articles. The data was analysed using bibliometric indicators such as the h-index, the total number of citations and the number of publications. An analysis of the data highlighted that the United States of America (USA) and Brazil have the highest number of single-country publications. Top authors were listed based on the h-index and the total number of citations. Top cited countries, institutions etc. were also analysed using this bibliometric study. This bibliometric evaluation provides a wide area of literature carried out to date. The existing knowledge can be used to direct future research.

RESUMO

INTRODUCTION: Our objective was to quantitatively assess and compare the bisphenol A (BPA) released from an orthodontic adhesive using a light-emitting diode device (LED) or a halogen light-curing unit (HLC) at 3 tip-to-bracket distances (0, 5, and 10 mm) and varying curing times using high-performance liquid chromatography. BPA release with self-etching and moisture-insensitive primers with light-cured and chemically cured composites was also evaluated. BPA release was correlated to the corresponding degree of conversion. METHODS: Our sample consisted of 598 stainless steel first premolar brackets. Of these, 520 were used for assessing BPA release and divided into 13 groups of 40 each. In groups I, II, and III, the composite was cured with the LED for 20 seconds at distances of 0, 5, and 10 mm, respectively. Groups IV, V, and VI were cured with the HLC for 40 seconds at the same 3 distances. Groups VII and VIII were cured for 5 and 10 seconds with the LED, and groups IX and X were cured for 10 and 20 seconds with the HLC at 0-mm distance. Groups XI, XII, and XIII consisted of brackets bonded with a self-etching primer and Transbond (3M Unitek, Monrovia, Calif), with a moisture-insensitive primer and Transbond, and with a chemically cured composite. The remaining 78 brackets were also divided into 13 groups and used for assessing the degree of conversion. RESULTS: The LED devices demonstrated significantly less BPA release and greater degrees of conversion (P <0.05). For both units, BPA release increased and the degree of conversion decreased as the tip distance increased and curing time decreased. The chemically cured group showed significantly less BPA release (P <0.05). Among the light-cured composites, those cured according to the manufacturers' recommendations (40 seconds and 0-mm distance for the HLC unit) released less BPA than did the self-etching primer and the moisture-insensitive primer. The degree of conversion was greatest for the chemically cured composite, whereas it was similar for the conventional, self-etching primer, and moisture-insensitive primer groups. However, correlations ranged from strongly negative to weakly positive between BPA release and degree of conversion. CONCLUSIONS: Clinicians should consider using LEDs in clinical practice and should keep the light-cure tip as close to the bracket as clinically possible. Curing time should be according to the manufacturer's recommendations. These steps will ensure less BPA release and a greater degree of conversion. Since chemically cured composites had less BPA release and a greater degree of conversion, they can be considered superior to light-cured composites in this aspect.
