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. -

Braces and Orthodontics Overview
Braces and Orthodontics Overview Orthodontic treatment is used to correct a “bad bite.” This condition, known as a malocclusion, involves teeth that are crowded or crooked. In some cases, the upper and lower jaws may not meet properly and although the teeth may appear straight, the individual may have an uneven bite. Protruding, crowded or irregularly spaced teeth and jaw problems may be inherited. Thumb-sucking, losing teeth prematurely and accidents also can lead to these conditions. Correcting the problem can create a nice-looking smile, but more important, orthodontic treatment results in a healthier mouth. That’s because crooked and crowded teeth make cleaning the mouth difficult, which can lead to tooth decay, gum disease and possibly tooth loss. An improper bite can interfere with chewing and speaking, can cause abnormal wear to tooth enamel, and can lead to problems with the jaws. Frequently Asked Questions • What are braces made from? o Braces (also called orthodontic appliances) can be as inconspicuous—or as noticeable— as you like. Brackets—the part of the braces that attach to each tooth—are smaller and can sometimes be attached to the back of the tooth, making the brackets less noticeable. o Brackets may be made of metal, ceramic, plastic or a combination of these materials. Some brackets are clear or tooth-colored. There are brackets shaped like hearts and footballs, and elastics (orthodontic rubber bands) in school colors or holiday hues such as red, white and blue. And there are gold-plated braces and glow-in-the-dark retainers. • Are they left in the mouth or can they be removed? o There are two types of orthodontic appliances: fixed, which are worn all the time and can only be removed by the dentist, and removable, which the patient can take out of the mouth. -
Risks and Complications of Orthodontic Miniscrews
SPECIAL ARTICLE Risks and complications of orthodontic miniscrews Neal D. Kravitza and Budi Kusnotob Chicago, Ill The risks associated with miniscrew placement should be clearly understood by both the clinician and the patient. Complications can arise during miniscrew placement and after orthodontic loading that affect stability and patient safety. A thorough understanding of proper placement technique, bone density and landscape, peri-implant soft- tissue, regional anatomic structures, and patient home care are imperative for optimal patient safety and miniscrew success. The purpose of this article was to review the potential risks and complications of orthodontic miniscrews in regard to insertion, orthodontic loading, peri-implant soft-tissue health, and removal.

Osseointegrated Dental Implants As Alternative Therapy to Bridge
SCIENTIFIC ARTICLE Osseointegrateddental implants as alternative therapy to bridge construction or orthodonticsin youngpatients: sevenyears of clinical experience Philippe D. Ledermann,DDS Thomas M. Hassell, DDS,PhD Arthur F. Hefti, DDS,PD Abstract Youngpatients often require fixed bridgeworkor orthodontictherapy in cases of traumatic tooth loss or congenitally missing teeth. Dentalimplants represent an alternative to the moreconventional treatment methods.We report positive experienceover a seven-year period with 42 titanium Ha-Ti implants in 34 patients aged 9 to 18 years. Fourteen implants were placed into preparedtooth sockets immediatelyafter traumatic luxation of anterior teeth in 12 patients aged9 to 18 years (medianage 16). Anadditional 22 patients (medianage 15.5, range 11 to 18) also received implants (N = 28), but these wereplaced only after healing of extraction sites, or as substitutes for congenitally missing teeth. Implants remainedin situ for an averageof 7.7 monthsbefore loading. Duringthe healing period, three implants were lost due to additional traumaand one becameinfected. The 38 remainingimplants osseointegrated and since have been loaded for five to 79 monthsin successful function. There was no difference between immediateand delayed implants in clinical success. These experiences demonstratethat appropriate, versatile, osseointegrated implants can provide a successful treatment methodfor youngpatients, without damagingadjacent teeth.

Disease/Medical Condition
Disease/Medical Condition HYPOTHYROIDISM Date of Publication: January 27, 2017 (also known as “underactive thyroid disease”; includes congenital hypothyroidism [also known as “neonatal hypothyroidism”] and Hashimoto’s thyroiditis [also known as “autoimmune thyroiditis”]; may manifest as “cretinism” [if onsets during fetal or early life; also known as “congenital myxedema”] or “myxedema” [if onset occurs in older children and adults]) Is the initiation of non-invasive dental hygiene procedures* contra-indicated? No. ◼ Is medical consult advised? – Yes, if previously undiagnosed hypothyroidism or enlarged (or shrunken) thyroid gland is suspected1, in which case the patient/client should see his/her primary care physician. Detection early in childhood can prevent permanent intellectual impairment. – Yes, if previously diagnosed hypothyroidism is suspected to be undermedicated (with manifest signs/symptoms of hypothyroidism) or overmedicated (with manifest signs/symptoms of hyperthyroidism2), in which case the patient/client should see his/her primary care physician or endocrinologist. Major stress or illness sometimes necessitates an increase in prescribed thyroid hormone. Is the initiation of invasive dental hygiene procedures contra-indicated?** Possibly, depending on the certainty of diagnosis and level of control. ◼ Is medical consult advised? – See above. ◼ Is medical clearance required? – Yes, if undiagnosed or severe hypothyroidism is suspected. ◼ Is antibiotic prophylaxis required? – No. ◼ Is postponing treatment advised? – Yes, if undiagnosed hypothyroidism is suspected (necessitating medical assessment/management) or severe hypothyroidism is suspected (necessitating urgent medical assessment/management in order to avoid risk of myxedema coma). In general, the patient/client with mild symptoms of untreated hypothyroidism is not in danger when receiving dental hygiene therapy, and the well managed (euthyroid) patient/client requires no special regard.
