Indexing Status: Scopus: Web of Science: PubMed:

Abstract

Bacterial plaque is a bio-film composed of microbes, organic and inorganic components attached to the soft and hard tissues of oral cavity. Dental plaque is the primary cause of periodontal diseases including gingivitis and periodontitis, dental caries, peri-implantitis, and stomatitis. From an ecological viewpoint, the oral cavity undergoes a continuous introduction and removal of both microorganisms and nutrients. In order to survive in oral cavity, bacteria need to adhere either to the soft or hard tissues in order to resist disruption forces. Dental literature was searched with key words of plaque, plaque formation, biofilm, material properties and plaque formation, composites, amalgam, glass ionomer, ceramics and dental implants. Dental materials properties were reviewed in relation to biofilm adherence. A very briefly, mechanical and chemical methods of plaque control were reviewed. Recent developments of bioactive restorative materials were reviewed for their surface characteristics and its influence on biofilm formation. It is hoped that dental professionals would find this narrative review helpful for their routine clinical practice to render, ecological friendly restorative dental treatments and material choices to improve the quality of life of their relatively oral hygiene compliant patients population.

Dent Med Probl. 2018 Dec;55(4). doi:10.17219/dmp/97311. Indexing Status: Scopus: Web of Science: PubMed: Abstract Background: Remineralization potential of dentifrices with novel compositions that can restore minerals back into incipient carious lesions has not been extensively studied so far. Objectives: The aim of this study was to assess the efficacy of a dentifrice based on novel fluoride incorporated bioactive glass in remineralizing artificial carious lesions in human enamel, and compare it with a standard fluoride-containing dentifrice. Material and methods: Twenty-four human extracted teeth were sectioned at the cementoenamel junction to obtain enamel blocks. These blocks (n = 24) were randomly divided into 3 groups, with each group containing 8 specimens: group 1 (negative control group; distilled water), group 2 (positive control group; fluoride toothpaste) and group 3 (test group; BioMinTM F toothpaste). Artificial carious lesions were produced in the enamel surfaces by exposing them to a demineralization solution (6% citric acid, pH 2.2) for 96 h. After demineralization, the specimens were brushed with manual toothbrushes in a toothbrush simulation machine (each sample received 800 strokes). For brushing the specimens from group 1, 20 mL of distilled water was used, for group 2 – 20 mL of slurry of toothpaste mixed with artificial saliva, and for TM group 3 – 20 mL of slurry of toothpaste (BioMin F) mixed with artificial saliva. The micro-hardness data (VHN – Vickers hardness number) was collected at baseline (sound enamel), post-demineralization and post- remineralization. Results: The biggest difference between the post-remineralization and post- demineralization values was observed in group 3 (mean VHN = 118.73), followed by group 2 (mean VHN =

60.54) and group 1 (mean VHN = 47.44). All the groups revealed significant differences (p < 0.05) when the post-demineralization and post-remineralization values were compared to baseline values within each group. Conclusion: The BioMinTM F group outperformed the other 2 groups in terms of remineralizing the demineralized enamel structure.

Abstract

Background: The demand for facial esthetics has increased dramatically to overcome the ongoing aging process and/or improve facial appearance. Objectives: The aim of this study was to evaluate the outcomes of using bilateral silicone implants for mandibular angle augmentation. Material and methods: The study involved a prospective analysis of the outcomes of the mandibular angle region augmentation with bilateral silicone implants in 58 patients (2 males and 56 females) within 1 year. All the data was collected either from patients’ interviews or their records, after receiving the ethical approval from the relevant hospital. The collected patients’ data was analyzed based on 3 main outcomes: occurrence of implant displacement, presence of postoperative infection and patient satisfaction. Only the patients who completed a follow-up of 6 months postoperatively were included in this study. Results: A total of 58 patients received bilateral silicone implants at the mandibular angle with a total of 116 implants, out of which 96 were found intact, with no evidence of complications. The total number of implants that were infected was 5 (4.3%), 16 implants were found displaced (13.8%) and only 3 patients of those without complications were dissatisfied with the final facial appearance (6%). Conclusion: Using solid silicone implants in the augmentation of the mandibular angle resulted in low postoperative infection and displacement rates, as well as in high patient satisfaction.

Abstract

Introduction: Patient satisfaction is associated with improved compliance and better health outcomes. However, the factors related to patient satisfaction are not fully understood. Aims: To evaluate patient satisfaction and the associated factors with facilities, services, and treatment received at a dental institution in Saudi Arabia. Materials and Methods: This cross-sectional study involved a convenience sample of male and female patients who visited a dental college in Dammam, Saudi Arabia. A questionnaire was designed using a five-point Likert scale to assess patient satisfaction. The instrument was piloted before its administration to study participants. Mann–Whitney U test was performed for statistical analysis. Results: The response rate was 81.9% as 262 out of 320 patients returned the questionnaire. The mean age of the patients was 34.7 years (SD±12.5). More males (65.3%) than females (34.7%) participated in the study. The highest mean score of patient satisfaction was reported for dental treatment (4.38), followed by facilities (4.34) and then appointments (4.27). Less educated patients (school education) than those with bachelor/master's degree were more satisfied with appointments (p=0.024), facilities (p =0.024), and treatment (p =0.016). Similarly, subjects aged 41-74 years demonstrated more satisfaction with facilities (p =0.001), and treatment (p =0.02) than those aged 17-40 years. However, gender, ethnicity, and monthly income were not significantly associated with patient satisfaction. Good quality of treatment was the main reason for visiting the institution. Conclusion: Most of the patients were satisfied with the dental services. Education and age of the patients were significantly associated with their satisfaction.

Indexing Status: Scopus: Web of Science: PubMed:

Abstract

Objectives: Glass Ionomer Cement (GIC) is routinely placed as a restorative material in dentistry. However, due to its poor physical properties, its use is limited to cases where the level of stress on the restoration is minimal. Improved formulations of GIC have been developed to overcome these drawbacks. The purpose of the study was to evaluate the flexural strength of a conventional GIC (Fuji IX) against the newly developed Glass Carbomer Cement (GCP). Materials and methods: A total of 80 blocks for Fuji IX and GCP were prepared and divided into 16 groups (n = 5). These groups were further categorized according to the storage medium (Artificial Saliva and Vaseline) and time intervals (24 hours, 1 week, 2 weeks and 4 weeks). A 3-point bending test was carried out, and statistical analysis was done using ANOVA and Tukey post hoc tests. Results: Fuji IX showed a mean flexural strength of 25.14 ± 13.02 MPa compared to 24.27 ± 12.57 MPa for GCP. There was no significant statistical difference between the two materials when compared under storage media. Both materials showed the highest value for flexural strength at 2 weeks of storage and lowest at 4 weeks. Conclusion:7 The storage media does not affect any relevant differences in the flexural strength of the specimens with reference to time. Time is the unique factor with relative influence on mean resistance to fracture. Further testing is required to evaluate the true potential of the newly developed GCP.

Introduction

Thirty years ago, the invention by Charles Hull of SLA (stereolithographic apparatus), or 3D printing, began a revolution in the way dentistry is practised today and will be in the future. Furthermore, 3D printing is not limited to dentistry; its impact is already being felt in many diverse industries, from aerospace to food processing. The paradigm shift from subtractive to additive manufacturing is gathering momentum and delivering products with microprecision and functionality, while at the same time reducing the carbon footprint. 3D printing is a technology that cannot be ignored. However, as with any new technology, the accompanying technophobic inertia is unavoidable. The purpose of this book is to ease the pain, infuse enthusiasm, and help the profession to take a dip, or even a plunge, into uncharted waters. Backed by scientific credence, 3D Printing in Dentistry 2019/2020 takes the reader on a journey to demystify the latest trends in digital dentistry; not only 3D printing, but the entire digital dental workflow, including intra-oral scanners, 3D printers, 3D materials, and CAD/CAM processes. The text, accompanied by numerous high-quality full-colour illustrations, furnishes the reader with information about the evolution of 3D printing and simplifies the complex technology behind it, relating it to daily dental practice. In the first section, the fundamental concepts of several revolutionary breakthroughs are discussed, while the second section presents clinical case studies that apply 3D printing in a variety of dental modalities and disciplines. However, as with so much technology that promises the world, a degree of caution is required. While the virtues of 3D printing are extolled, its limitations are also critiqued. To summarise, 3D Printing in Dentistry 2019/2020 is an original and enticing book describing the state of the art of 3D printing in dentistry today. The book is also a 'stem cell' for the incredible possibilities that lie ahead.

Abstract

Introduction: A survey was done to assess the training and education of dental practitioners who participate in implant dentistry in both the public and private sectors in the Eastern Province of Saudi Arabia. This included the preferences for various implant systems, clinical complications and the barriers encountered in implant therapy.

Materials and method:

Materials and Methods: The study was conducted between November 2015 and April 2016. A self-administered questionnaire was distributed to a convenient sample of 55 dental implant professionals in public and private healthcare facilities. Results: Among 55 implant professionals, only 38 participants responded to the questionnaire. Of these, 65.8% were in the private sector, and 34.2% were in the public sector. The majority of respondents were Oral Surgeons (44.7%), followed by General Practitioners (21.1%), Periodontists (18.4%), and

Prosthodontists (13.2 %). Fifty-two percent of respondents had received formal post-graduate training in implant placement, this also being in combination with courses and/or seminars (50%), and/or by Fellowship/Board training (15.7%). The most commonly used implant systems were Straumann (34.2%), Astra Tech (28.9%) and Zimmer (23.7%) respectively. Peri-implant mucositis and peri-implantitis were the most commonly encountered clinical complications, followed by local infection, failed osseointegration and dehiscence/fenestration. Conclusion: The importance of continuing education courses is also conversed. The biggest barrier to implant treatment was found to be the actual cost of the implants for the patient.

Abstract

Glass fiber-based materials have gained interest for use in biomedical and dental applications. The aim of this study was to make E-glass fiber bioactive by a novel method using the microwave irradiation technique. Industrial E- glass fibers were used after surface activation with the hydrolysis method. The ratio of calcium and phosphorous precursors was set at 1.67. After maintaining the pH of the calcium solution, E-glass fibers in two ratios, i.e. 30% (nHA/E30) and 50% (nHA/E50) wt/wt, were added. The phosphorous precursor was added later, and the solution was irradiated in a microwave to obtain nano-hydroxyapatite (nHA) particles on E-glass fibers. The structural, physical and in vitro biocompatibility analyses of the resulting materials were conducted. The expression of osteopontin (OPN) and collagen (Col) type 1 was measured by reverse transcription polymerase chain reaction (RT-PCR) and comparison was made between all the groups. Fourier transform infrared spectroscopy and x-ray diffraction showed characteristic peaks of nHA, and a change in the peak intensities was observed with an increase in the concentration of E-glass fibers. Scanning electron microscopic (SEM) images confirmed the homogenous adhesion of nHA spherical particles all over the fibers. Cell viability with mesenchymal stem cells showed growth, proliferation, and adhesion. All the materials were able to upregulate the expression of the OPN and Col, where gene expression was highest in nHA followed by nHA/E30 and nHA/E50. The bioactive glass fibers were synthesized in the shortest time and showed osteogenic properties. These materials have the potential for use in bone tissue engineering, dental prosthesis, and tooth restoration.

Indexing Status: Scopus: Web of Science: PubMed:

Abstract

Over extension of denture border is the main cause of denture-induced fibrous hyperplasia (DIH) especially with immediate denture. We report a 53-year-male with the chief complaint of a loose immediate maxillary denture as well as pain and discomfort during mastication and asking for new denture. Patient was examined, and medical history was taken. Intraoral examinations revealed that folding with deep fissure covered by white granulation tissue in the maxillary right labial sulcus and left buccal sulcus related to the overextended thin denture borders and diagnosed as DIH. Treatment started with border adjustment and finally new denture fabrications. Exact

Denture border extension verifications and adjustments during insertion is the most important step as well as patient education and periodic follow up after denture insertion for prevention of DIH occurrence.

Abstract

OBJECTIVE: The objective of this study was to measure the push-out bond strength of three types of mineral trioxide aggregate (MTA) materials in root dentin. METHODS: The study was carried out at the College of Dentistry, Imam Abdulrahman Bin Faisal University from March 2014 to January 2015. Thirty extracted maxillary central incisors were selected, instrumented, irrigated, and randomly assigned into three groups (n = 10): Group 1 - Ortho MTA; Group 2 - MTA Angelus; and Group 3 - ProRoot MTA. Materials were mixed following the manufacturers' recommendations and canals were filled. Teeth were stored in distilled water for 6 months. The push-out bond strength was evaluated using 2-mm thick coronal root sections. The data were analyzed with one-way ANOVA and Tukey-Kramer multiple comparison tests statistically significant at P < 0.05. RESULTS: The mean bond strength values were 68.69 ± 29.63 MPa for Ortho MTA, 42.54 ± 32.78 MPa for MTA Angelus, and 72.75 ± 26.27 MPa for ProRoot MTA groups. There were no significant differences between the bond strengths of tested materials (P > 0.05). CONCLUSION: Ortho MTA, MTA Angelus, and ProRoot MTA materials showed similar push-out bond strength values in root dentin.

Indexing Status: Scopus: Web of Science: PubMed:

Abstract

PURPOSE: Alveolar ridge preservation procedures have been advocated to minimize postextraction dimensional loss. There is a need for systematic analyses of clinical factors affecting the outcomes of these procedures in order to improve their clinical outcomes. This systematic review and meta-analysis aimed to assess the efficacy of alveolar ridge preservation procedures in terms of hard tissue dimensional changes and to determine clinical factors affecting outcomes of these procedures. MATERIALS AND METHODS: Studies comparing alveolar ridge preservation procedures with tooth extraction alone that reported quantitative outcomes for hard tissue dimensional changes were included. The primary outcome variable was horizontal dimensional changes of alveolar bone. Subgroup analyses evaluated effects of wound closure, flap elevation, type of grafting materials, use of barrier membranes, use of growth factors, socket morphology, and the position of teeth on outcomes of alveolar ridge preservation procedures. RESULTS: Twenty-one studies were included, and quantitative analyses were performed for seven outcome variables. Significant differences between alveolar ridge preservation and control sites were found for six outcome variables, all favoring alveolar ridge preservation procedures. The magnitude of effect for the primary outcome variable (horizontal dimensional changes of alveolar bone) was 1.86 mm (95% CI = 1.44, 2.28; P < .001). This magnitude of effect for the primary variable (as determined by subgroup analysis) was also significantly affected by type of wound closure (P = .033), type of grafting materials (P = .001), use of barrier membranes (P = .006), use of growth factors (P = .003), and socket morphology (P < .001). CONCLUSION: Alveolar ridge preservation procedures are effective in minimizing postextraction hard tissue dimensional loss. The outcomes of these procedures are affected by morphology of extraction sockets, type of wound closure, type of grafting materials, use of barrier membranes, and use of growth factors.
