ABSTRACT
OBJECTIVES: Restorative Dentistry and Endodontics (Restor Dent Endod; RDE) is an English-language journal published by the Korean Academy of Conservative Dentistry, and it has been online since 2012 with quarterly publications. The purpose of this paper was to review and analyze the publications in this journal since its inception and over the 7-year period from 2012 to 2018. MATERIALS AND METHODS: This paper assessed the number, type, and subject of articles published, as well as authorship patterns and article citations of the journal over a 7-year period. The citation indicator for the journal (h-index) was assessed using Google Scholar. RESULTS: The number of articles per issue has remained relatively consistent in the 7 years that were analyzed. An analysis of the article types revealed various categories of review articles. Original research articles accounted for the most articles per volume. Twice as many articles per volume were on endodontic topics than on restorative subjects. Articles published in RDE have been widely cited in Synapse, Crossref, and PubMed Central. A country-wise mapping of authors' institutions revealed significant contributions from authors around the world. With an h-index of 24, RDE ranks third among journals in its specialty. The most cited articles were open lectures on statistics and research articles on recent concepts, technology, and materials. CONCLUSION: Over the last 7 years, RDE has served as a platform for a large number of manuscripts in the field of restorative dentistry and endodontics.
ABSTRACT
Magnetic resonance imaging (MRI) is an advanced diagnostic tool used in both medicine and dentistry. Since it functions based on a strong uniform static magnetic field and radiofrequency pulses, it is advantageous over imaging techniques that rely on ionizing radiation. Unfortunately, the magnetic field and radiofrequency pulses generated within the magnetic resonance imager interact unfavorably with dental materials that have magnetic properties. This leads to unwanted effects such as artifact formation, heat generation, and mechanical displacement. These are a potential source of damage to the oral tissue surrounding the affected dental materials. This review aims to compile, based on the current available evidence, recommendations for dentists and radiologists regarding the safety and appropriate management of dental materials during MRI in patients with orthodontic appliances, maxillofacial prostheses, dental implants, direct and indirect restorative materials, and endodontic materials.
ABSTRACT
CONTEXT: One of the important goals of root canal therapy is disinfection aided by irrigation and intracanal medicaments. Commonly used nonsteroidal anti-inflammatory agents have shown anti-bacterial activity, thus, when used as intracanal medicaments, nonantibiotic agents have the potential to provide anti-inflammatory, local analgesic, and anti-bacterial activity. AIM: The aim of this study is to evaluate and compare the anti-bacterial efficiency of anti-inflammatory nonantibiotics ibuprofen and diclofenac, and routinely used intracanal dressing calcium hydroxide (Ca[OH]2), against Enterococcus faecalis, in an endodontic model. MATERIALS AND METHODS: A total of 76 single-rooted mandibular premolar teeth were decoronated and instrumented up to F4-ProTaper rotary. Apical foramen was sealed with composite resin, and all external surfaces made impermeable with nail varnish, except for coronal access. Roots were autoclaved (121°C for 20 min), placed in Eppendorf tubes, and contaminated with E. faecalis for 14 days. Colony-forming unit (CFU) counts were taken before (CFU-1), and after intracanal medication (CFU-2) by paper point sampling. Test medicaments (Group-1: ibuprofen, Group-2: diclofenac, Group-3: Ca[OH]2) were mixed with distilled water (1:1 w/v), placed into root canals, temporarily sealed, and incubated (37°C; 7 days). Group-4 received no medicament (control). Kruskal-Wallis ANOVA was used to compare the four groups and Mann-Whitney U-test for pair-wise comparisons. RESULTS: Within the limitations of the study, anti-inflammatory nonantibiotics (ibuprofen; diclofenac) were shown to have anti-bacterial effect against E. faecalis. CONCLUSION: Since nonsteroidal anti-inflammatory drugs (NSAIDs) have an anti-bacterial effect, it is possible to replace Ca(OH)2 with NSAIDs, or even combine them to form a cocktail of local disinfectants to optimize canal disinfection.
ABSTRACT
Dental erosion is frequently overlooked in clinical practice. The management of erosion-induced damage to the dentition is often delayed, such that extensive occlusal rehabilitation is required. These cases can be diagnosed by a careful clinical examination and a thorough review of the patient's medical history and/or lifestyle habits. This case report presents the diagnosis, categorization, and management of a case of gastro-esophageal reflux disease-induced palatal erosion of the maxillary teeth. The early management of such cases is of utmost importance to delay or prevent the progression of damage both to the dentition and to occlusal stability. Non-invasive adhesively bonded restorations aid in achieving this goal.
ABSTRACT
This case report presents the categorization and management of two cases of C-shaped canals in need of root canal treatment, based on the available classification systems. The prediction of C-shaped root canal morphology using radiography and clinical picture is possible through the application of the classification schemes proposed in literature. A modified cold lateral compaction technique is described for obturation of C-shaped canals partly united by a narrow isthmus.
ABSTRACT
CONTEXT: Being integral to root canal therapy, obturation can be performed adequately only after the removal of intracanal medicament. One technique involves the use of chelating agents such as ethylenediaminetetraacetic acid (EDTA) and citric acid. Etidronic acid, a relatively new chelator, has smear layer removal ability and lesser dentinal erosion. It is untested in calcium hydroxide (Ca[OH]2) medicament removal. AIM: The aim of this study was to compare the efficiency of irrigation protocols (EDTA, citric acid, and etidronate) in Ca(OH)2 removal. MATERIALS AND METHODS: Forty-five single-rooted mandibular premolars were decoronated, instrumented, and filled with Ca(OH)2. After 7 days incubation, Ca(OH)2 was removed by three irrigation protocols (Group-I: 17% EDTA; Group-II: 10% citric acid; and Group-III: 18% etidronate). Roots were split and analyzed (scanning electron microscope, ×1500). Chelator solution pH was tested. Data were analyzed by Kruskal-Wallis ANOVA and Mann-Whitney U-test. RESULTS: Group-III (coronal-third) and Groups-I and II (middle-third) had highest cleanliness scores; Groups-II and III (apical-third) had lowest scores. Comparing the thirds, all groups showed difference in scores. pH of Groups-I, II, and III were 6.8, 1.4, and 0.3, respectively. CONCLUSION: The solution pH of citric acid and etidronate impacts their Ca(OH)2 removal efficiency in different ways: the highly alkaline pH of Ca(OH)2 increases citric acid pH toward neutrality, where it becomes an inefficient chelator; on the contrary, high acidity of etidronate compensates for its weaker chelation. Etidronate may not require 5 min duration for Ca(OH)2 removal due to the likelihood of dentinal erosion.
