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. -
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.

The Rationale for the Three Monthly Peridontal Recall Interval

J. Darcey1 and M. Ashley2 VERIFIABLE CPD PAPER There is significant evidence to support the regular review of patients with chronic periodontitis. There is, however, com- paratively little evidence to demonstrate how often such reviews should take place. This paper looks at the periodontal healing period, the risks of periodontal progression and current thinking about maintenance programmes. It thus attempts to establish some guidelines that practitioners may use when calculating recall intervals. Clinical relevance The choice of individual, patient-focused recall intervals is essential to limit disease progression and maintain healthy periodontal tissues.

Periodontal Disease
Periodontal Disease Department of Orthodontics and Restorative Dentistry Information for Patients i University Hospitals of Leicester NHS Trust What is Periodontal Disease (Gum Disease)? Periodontal disease is an inflammatory condition affecting the tissues that surround and support the teeth. Periodontal disease leads to pocket formation and bone loss. If untreated, periodontal disease can lead to loosening and loss of teeth. Signs of gum disease include: • Red or purple gums • Swollen or Bleeding gums • Mobile or migrated teeth • Gum recession • Bad breath Gum disease may be present in the absence of these signs. Risk Factors include: • Plaque and calculus • Smoking • Diabetes • Genetic predisposition Obesity, poor nutrition and stress have also been suggested as risk factors. 2 Why is treatment important? Treatment of periodontal disease can help you retain your teeth for longer. As the inflammation around your teeth resolves, your gums will appear healthier, bleeding should stop and tooth mobility may improve. There is also increasing evidence that treatment of periodontal disease can improve your general health. For example, in diabetic patients, good control of periodontal disease can help control blood sugar levels. What can I do to help my gums? Good oral hygiene is the most important factor in ensuring a good outcome with periodontal treatment. You should brush your teeth with a fluoride containing toothpaste for three minutes, twice daily. When you brush your teeth you must ensure you also brush the gum margin. This prevents plaque building up in this area. Bleeding gums is a sign that your gums are not clean enough. If good cleaning is maintained the gums should stop bleeding within two weeks. -
