Clinically Effective Regenerative Therapy For Primary Endodontic Lesions With Secondary Periodontal Lesions: A Case Report, Martina Amalia, Budi Budi, Iceu Estu Kurmaena, Nevi Yanti, Hesty Nurcahyanti, Aini Hariyani Nasution

Journal of Dentistry Indonesia

The diagnosis and prognosis of teeth with endo-perio lesions present a major challenge for dentists. Proper diagnosis is critical in determining treatment and the long-term prognosis. However, treating complex endodontic and periodontal lesions is one of the most common challenges in current clinical practice. The coexistence of pulpal and periodontal tissue damage may complicate diagnosis and further influence dental prognosis. This article consists of a case report evaluating the efficacy of xenografts and resorbable membrane pericardium in treating bifurcation lesions associated with periodontal lesions of the left mandibular first molar. A 22-year-old female patient was referred by conservative dentistry with …

Shore A Hardness And Fourier Transform Infrared Spectrophotometer Analysis Of Thymol-Modified Maxillofacial Silicone Material, Manar Hussein Ramadhan, Faiza M. Abdul-Ameer

Maaen Journal for Medical Sciences

The longevity of any prosthesis depends on the materials from which it was fabricated, which is why defects in the material properties may reduce the service life of the prosthesis and necessitate its replacement. This study aims to test the influence of incorporating different weight percentages of thymol micro-powder into the maxillofacial silicone matrix on Shore A hardness of the silicone. Room-temperature vulcanised VST-50 maxillofacial silicone was used to prepare the study specimens. Thymol micro-powder was incorporated into the silicone matrix in two percentages (0.75 wt.% and 1 wt.%). 30 specimens were prepared and then subdivided equally into three groups, …

Photocurable Ionized Vinylimidazole Liquid Salt For Antibacterial Application, Gina Park, Lisa Ahlberg, Robert Zdor

Celebration of Research and Creative Scholarship

There has been an increasing demand for antibacterial dental composite as it can prevent the biofilm formation and the adhesion of bacteria after the treatment causing the consequential cavities. Previous study explored the antibacterial activity of the heterogenous mixture of heterocyclic polymer and resin. It showed limitations as the mixture did not show antibacterial activity since the mixture could only contain a small amount of heterocyclic polymer within the resin due to its inconvenience of shaping and low miscibility. To overcome this limitation, this research focused on synthesizing heterocyclic antibacterial monomer liquid salt and curing it with UV light to …

Fabrication And Characterization Of Nylon 6 Fiber Via Wet Spinning Method For Application As A Reinforcing Material For A Direct Dental Bridge, Dissa Kirana Wijaya, Nina Djustiana, Yanwar Faza, Arief Cahyanto, Andri Hardiansyah

Makara Journal of Science

Nylon is a biocompatible thermoplastic polymer that is well known for its excellent fracture resistance, making it suitable for fabricating fiber-reinforced composite (FRC)-based dental bridges. FRC is widely used in dentistry. This study aimed to investigate the structural and morphological characteristics of the nylon 6 fiber prepared using five different weights of nylon 6 dissolved in formic acid. The nylon 6 fiber was successfully fabricated via a simple wet spinning method using water as a coagulant. The fiber was then characterized using Fourier transform infrared (FTIR) spectroscopy, optical microscopy, and scanning electron microscopy. FTIR spectroscopy confirmed the presence of nylon …

Oral Leukoplakia: Diagnosis And Management Revisited, Isaäc Van Der Waal

Journal of Dentistry Indonesia

The definition of oral leukoplakia has not much changed during the past five decades and is still a definition by exclusion of ‘known’ lesions. Therefore, a diagnosis of leukoplakia is not always a straightforward one for the clinicians and, to some extent, also for the pathologists. The traditional clinical classification in homogeneous and nonhomogeneous leukoplakia may just be simplified into leukoplakia (thin and thick/verrucous) and erythroleukoplakia. In spite of numerous reported predictive molecular and genetic parameters of malignant transformation, the presence and grade of epithelial dysplasia as assessed by histopathological examination is still the most important one. Of the various …

Local Chlorhexidine Delivery For Periodontal Infection Therapy: A Short Review, Muhammad Guruh Najmudin, Azizah Intan Pangesty, Rini Riastuti, Sunarso Sunarso, Abdul Halim Abdullah

Journal of Materials Exploration and Findings

Oral diseases affected more than half of the world’s population. Periodontitis is the second biggest threat to oral health after dental caries. Periodontitis is an inflammation inside periodontal pockets caused by pathogenic microbial colonies which lead to destruction of bone tissue and soft tissue. Chlorhexidine gluconate is an antimicrobial agent that effective to destroy pathogenic microbial and cure periodontitis. Chlorhexidine gluconate is given locally using a carrier material to the infected area. There are several materials that can be used to deliver Chlorhexidine gluconate to the infected periodontal tissue such as gel, liquid (mouthwash), and chip. This short review aims …
