Abstract

Introduction: Varnish is one of the dental materials that can be used to protect the pulp. Raw materials for making varnish were easy to be obtained using simple technique and composition. Self-processed varnish which has 40 gr of copal, 50 ml of 95% alcohol and 10 ml of chloroform was produced. When applied, varnish formed a thin film layer which tend to porous. The purpose of this study was to analyze the comparison between porosity which formed in film layer of self-processed and  factory varnish. Method: This study was true experimental with  12 third upper molars that had been cut horizontally as specimens and were divided into 2 groups as treated and control groups. First group had 1, 2, 3 and 4 times application of processed varnish as treated sample and second group samples were applied with factory varnish as control sample. Porosity was tested using SEM then its percentage was calculated by comparing the  porosity and the tooth area. The data was then tested  with t- independent test. Result: The result showed that self-processed varnish obtained larger percentage of porosity. Started at the third application time, both processed and factory varnish showed no porosity. Conclusion: The conclusion of this study was that there is difference between  porosity which formed in film layer of self-processed and  factory varnish.

Abstract

Periodontitis is a common chronic oral disease which if left untreated may cause mobility to loss of teeth. Periodontitis is local infection so a therapy using a local drug delivery system was more convenient than a conventional drug delivery system because the probability of side effects emergent is bigger. There are some drug delivery system types in periodontitis therapy and basically, these systems are using a polymer as a matrix by inserting a therapeutic agent into it so creating a composite structure. This study aims to provide a brief review of polymer-based composites utilized as local drug delivery systems for periodontitis therapy. A comprehensive literature review was conducted to gather information on the various types of polymer-based composites employed in periodontitis therapy. Key aspects such as polymer selection, drug loading methods, and therapeutic efficacy were analyzed. The results show Polymer-based composites have shown significant potential as effective local drug delivery systems for periodontitis treatment. The choice of polymer matrix, drug incorporation techniques, and release kinetics play crucial roles in determining the therapeutic outcomes. Various polymers, including biodegradable and non-biodegradable ones, have been explored for their suitability in this application, with promising results reported in preclinical and clinical studies.
