Owing to their properties such as biocompatibility, tunable mechanical properties, permeability toward oxygen, nutrients, and the ability to hold a significant amount of water, hydrogels have wide applications in biomedical research. They have been engaged in drug delivery systems, 3D cell culture, imaging, and extracellular matrix (ECM) mimetics. Injectable hydrogels represent a major subset of hydrogels possessing advantages of site-specific conformation with minimal invasive techniques. It preserves the inherent properties of drug/biomolecules and is devoid of any side effects associated with surgery. Various polymeric materials utilized in developing injectable hydrogels are associated with the limitations of toxicity, immunogenicity, tedious manufacturing processes, and lack of easy synthetic tunability. Peptides are an important class of biomaterials that have interesting properties such as biocompatibility, stimuli responsiveness, shear thinning, self-healing, and biosignaling. They lack immunogenicity and toxicity. Therefore, numerous peptide-based injectable hydrogels have been explored in the past, and a few of them have reached the market. In recent years, minimalistic dipeptides have shown their ability to form stable hydrogels through cooperative noncovalent interactions. In addition to inherent properties of lengthy peptide-based injectable hydrogels, dipeptides have the unique advantages of low production cost, high synthetic accessibility, and higher stability. Given the instances of expanding significance of injectable peptide hydrogels in biomedical research and an emerging recent trend of dipeptide-based injectable hydrogels, a timely review on dipeptide-based injectable hydrogels shall highlight various aspects of this interesting class of biomaterials. This concise review that focuses on the dipeptide injectable hydrogel may stimulate the current trends of research on this class of biomaterial to translate its significance as interesting products for biomedical applications.
Purpose: The inter-disciplinary approach to practise and also should constantly update their knowledge to keep up with the demands that this field presents.
Aim: The aim of this study was to evaluate the knowledge, attitude and practice of Esthetic dentistry amongst the practicing dentists of private dental colleges in Navi Mumbai, through a questionnaire- based study.
Materials and Methods: Self-administered KAP (Knowledge, Attitude, Practise) questionnaires were distributed amongst the practicing dentists of private dental colleges in Navi Mumbai. A total of 100 questionnaires were distributed.
Statistical analysis used: Pearson’s chi. Sq. test was applied and the likelihood ratio calculated for each question. Independent T Test was applied for equality of means between the groups, i.e. both gender and graduate and post graduate qualifications.
Results: Most of the dentists were aware of the field and practise of Esthetic dentistry, although there were some differences found between the general dentists and specialists in adopting and accepting new dental procedures. According to them, Finances played a major role in opting for an esthetic treatment by patients.
Conclusion: With the advances in esthetic dentistry and increased level of patients’ expectations and awareness, practicing dentists should be well versed with the same, by attending continuing dental education programs and courses to update their skill and knowledge. Also Finances plays a major role in opting for an esthetic treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
