Comparison of a Tridimensional Cephalometric Analysis Performed
Maspero et al. Progress in Orthodontics (2019) 20:40 https://doi.org/10.1186/s40510-019-0293-x RESEARCH Open Access Comparison of a tridimensional cephalometric analysis performed on 3T- MRI compared with CBCT: a pilot study in adults Cinzia Maspero1,2*† , Andrea Abate1,2†, Francesca Bellincioni1,2†, Davide Cavagnetto1,2†, Valentina Lanteri1,2, Antonella Costa1 and Marco Farronato1,2 Abstract Objective: Since the introduction of cone-beam computed tomography (CBCT) in dentistry, this technology has enabled distortion-free three-dimensional cephalometric analysis for orthodontic and orthognathic surgery diagnosis. However, CBCT is associated with significantly higher radiation exposure than traditional routine bidimensional examinations for orthodontic diagnosis, although low-dose protocols have markedly reduced radiation exposure over time. The objective of this preliminary feasibility study is to compare the accuracy and diagnostic capabilities of an already-validated three-dimensional cephalometric analysis on CBCT to those of an analysis on 3-T magnetic resonance imaging (3T-MRI) to assess whether the latter can deliver a comparable quality of information while avoiding radiation exposure. Materials and methods: In order to test the feasibility of three-dimensional cephalometry on 3T-MRI, 18 subjects (4 male; 14 female) with mean age 37.8 ± SD 10.2, who had undergone both maxillofacial CBCT and maxillofacial 3T-MRI for various purposes within 1 month, were selected from the archive of the Department of Dentistry and Maxillofacial Surgery of Fondazione Ospedale Policlinico Maggiore, IRCCS, Milano, Italy. A three-dimensional cephalometric analysis composed of ten midsagittal and four bilateral landmarks and 24 measurements (11 angular, 13 linear) was performed on both scans using Mimics Research® v. -
TITLE: Photo-Activated Disinfection Therapy for Dental Surgery: Review of the Clinical Effectiveness
TITLE: Photo-Activated Disinfection Therapy for Dental Surgery: Review of the Clinical Effectiveness DATE: 11 September 2013 CONTEXT AND POLICY ISSUES The oral cavity harbors more than 700 prokaryote species;1 most of these species are normal flora of the healthy oral cavity.2 Some of these microorganisms are responsible for oral pathologies. Bacteria such as Actinobacillus actinomycetemcomitans, Prevotella intermedia, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia are responsible for common forms of periodontal diseases,3 and Bacteroides, Peptostreptococcus, and microaerophilic Streptococcus species may cause osteomyelitis of the jaw.4 During a surgical intervention, disinfection of the oral cavity is attempted by using different chemical solutions such as chlorhexidine and iodine. This is done to prevent, or at least reduce the risk of wound infections or bacteremia following the surgical intervention.5 In the case of periodontal and endodontic treatments, mechanical cleaning of the affected surfaces are believed to be the gold standard.6 Photodynamic antimicrobial chemotherapy or light-activated disinfection is a technology based on the production of free oxygen radicals capable of affecting the membranes of microorganisms.7 The technique is composed of a photosensitizer substance that can be activated with a suitable wave length and light source. The photosensitizer, usually toluidine blue, is activated with a light source. After its activation, it produces energy capable of transforming the surrounding oxygen into free radicals. The free radical then attacks the exposed microorganisms.7 Photodynamic chemotherapy may be used in dentistry to reduce the bacterial load in cases of periodontal lesions and during root canals. Another potential use of this technique is as a pre- surgical disinfection method for the oral cavity to prevent oral flora from penetrating the bone and submucosal tissues during surgery. -
Enhancing the Predictability of Clear Aligners
Enhancing Predictability of Clear Aligners Bowman DRASTIC PLASTIC: ENHANCING THE PREDICTABILITY OF CLEAR ALIGNERS S. Jay Bowman ABSTRACT Once limitations of clear aligner treatments were identified, conceptualizing techniques to improve the predictability in producing desired results was the next logical step. A variety of concepts, methods, and adjuncts have subsequently been introduced to enhance the efficiency and effectiveness of clear aligners. As a consequence, the scope of biomechanics and type of malocclusions that can be more predictably treated has increased. As one example, the inclusion of miniscrew temporary skeletal anchorage has permitted the addition of direct and indirect anchorage to support and control more predictable programmed tooth movements with aligners. After reviewing the reported shortcomings of plastic aligners, this chapter explores possibilities for improving predictability of aligner therapy. KEY WORDS: Clear Aligners, Miniscrews, Bootstrap Elastic, Attachments, Bonded Buttons INTRODUCTION It has been 20 years since the introduction of a commercialized clear aligner product to the orthodontic marketplace. Based on suggestion by Harold D. Kesling over 50 years earlier, Invisalign and later, increasingly numerous propriety alternatives have come to pass; including the exponential growth of so-called direct-to-consumer (DTC or DIY) offerings [1]. From the original questions of whether even “acceptable” results could be obtained from a sequence of aligners, these queries have now evolved into: Is an orthodontist even needed to be interjected between the manufacturer’s plastic and their “customers?” So, the idea of moving teeth with plastic was nothing new, but the use of software to attempt to predict desired tooth movement and the associated 3D representations of individual tooth position were innovative. -

TITLE PAGE Treatment Outcome with Orthodontic Aligners and Fixed
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2020 Treatment outcome with orthodontic aligners and fixed appliances: a systematic review with meta-analyses Papageorgiou, Spyridon N ; Koletsi, Despina ; Iliadi, Anna ; Peltomaki, Timo ; Eliades, Theodore Abstract: Background: The use of orthodontic aligners to treat a variety of malocclusions has seen considerable increase in the last years, yet evidence about their efficacy and adverse effects relative to conventional fixed orthodontic appliances remains unclear. Objective: This systematic review assesses the efficacy of aligners and fixed appliances for comprehensive orthodontic treatment. Search methods: Eight databases were searched without limitations in April 2019. Selection criteria: Randomized or matched non-randomized studies. Data collection and analysis: Study selection, data extraction, and risk of bias assessment was done independently in triplicate. Random-effects meta-analyses of mean differences (MDs) or relative risks (RRs) with their 95% confidence intervals (CIs) were conducted, followed by sensitivity analyses, and the GRADE analysis of the evidence quality.Results: A total of 11 studies (4 randomized/7 non-randomized) were included comparing aligners with braces (887 patients; mean age 28.0 years; 33% male). Moderate quality evidence indicated that treatment with orthodontic aligners is associated with worse occlusal outcome with the American Board of Orthodontics Objective Grading System (3 studies; MD = 9.9; 95% CI = 3.6-16.2) and more patients with unacceptable results (3 studies; RR = 1.6; 95% CI = 1.2-2.0). No significant differences were seen for treatment duration. The main limitations of existing evidence pertained to risk of bias, inconsistency, and imprecision of included studies. -
Bleeding Disorders of Importance in Dental Care and Related Patient Management
Clinical P RACTIC E Bleeding Disorders of Importance in Dental Care and Related Patient Management Contact Author Anurag Gupta, BDS; Joel B. Epstein, DMD, MSD, FRCD(C); Robert J. Cabay, MD, DDS Dr. Epstein Email: [email protected] ABSTRACT Oral care providers must be aware of the impact of bleeding disorders on the manage- ment of dental patients. Initial recognition of a bleeding disorder, which may indicate the presence of a systemic pathologic process, may occur in dental practice. Furthermore, prophylactic, restorative and surgical dental care of patients with bleeding disorders is best accomplished by practitioners who are knowledgeable about the pathology, com- plications and treatment options associated with these conditions. The purpose of this paper is to review common bleeding disorders and their effects on the delivery of oral health care.
