Effects of impaction severity of treated palatally displaced canines on periodontal outcomes: a retrospective study.

Prog Orthod 2019 Feb 4;20(1). Epub 2019 Feb 4.

Department of Medical, Surgical and Health Sciences, University of Messina, Messina, Italy.

Background: Even though periodontal health was suggested to be not related to the traction technique, some other variables might influence the esthetic outcome of palatally displaced canines (PDC) when aligned, such as the initial position and impaction rate of the canine before treatment. The purpose of the present study was therefore to evaluate the existing correlations between periodontal health outcome of PDC after their exposure and alignment and their initial position identified according to the different rates of impaction severity.

Materials And Methods: The final sample enrolled 293 PDC which satisfied inclusion and exclusion criteria. Read More

Effect of the vertical position of the canine on the frictional/orthodontic force ratio of Ni-Ti archwires during the levelling phase of orthodontic treatment.

J Oral Sci 2018 Sep 31;60(3):336-343. Epub 2018 May 31.

Department of Orthodontics, Nihon University School of Dentistry.

This study investigated the effect of the vertical position of the canine on changes in the frictional/orthodontic (F/O) force ratio of nickel-titanium (Ni-Ti) archwires during the initial levelling phase of orthodontic treatment. Frictional and orthodontic forces were measured by using low-friction brackets and Ni-Ti archwires with three different cross-sectional sizes and force types. To simulate canine malocclusion (first premolar extraction case), the upper right canine was displaced gingivally by 1 to 3 mm and the inter-bracket distance between the upper right lateral incisor and second premolar was set at 15 mm or 20 mm.

Atypical radiographic presentation of a horizontal mid-root fracture in a maxillary central incisor tooth.

J Conserv Dent 2018 Mar-Apr;21(2):233-236

Division of Conservative Dentistry and Endodontics, Centre for Dental Education and Research, All India Institute of Medical Sciences, New Delhi, India.

Prognosis of a horizontal mid-root fracture is favorable, primarily because the dental pulp tends to maintain its vitality and the fracture segments are completely intraalveolar. Healing usually occurs with deposition of calcified tissue. However, if the segment coronal to the fracture becomes nonvital and infected, healing occurs by interposition of granulation tissue.

Successful Treatment of a Persistent Oroantral Fistula via Transbuccal and Transnasal Endoscopic Debridement in a Horse.

J Vet Dent 2018 Mar;35(1):28-34

1 Equine Department, VetAgro-Sup, University of Lyon, Marcy l'Etoile, France.

We report an unusual case of a young Quarter Horse with a large dental fracture fragment displaced into the maxillary sinus, leaving an oroantral communication that caused food impaction and metaplastic calcification in the sinus and facial deformation with cutaneous fistulation. Oral extraction of a remaining tooth fragment from its alveolus was succeeded by a maxillary sinusotomy for removal of the abnormal sinus contents. Since the oroantral fistula did not heal spontaneously following the placement of a silicone dental prosthesis, minimally invasive transbuccal and transnasal endoscopic approaches were used to encourage closure of the oroantral fistula by alveolar granulation.

Open versus closed surgical exposure of canine teeth that are displaced in the roof of the mouth.

Cochrane Database Syst Rev 2017 08 21;8:CD006966. Epub 2017 Aug 21.

Academic Unit of Oral Health and Development, School of Clinical Dentistry, University of Sheffield, Claremont Crescent, Sheffield, UK, S10 2TA.

Background: Palatally displaced canines or PDCs are upper permanent canines, commonly known as 'eye' teeth, that are displaced in the roof of the mouth. This can leave unsightly gaps, cause damage to the surrounding roots (which can be so severe that neighbouring teeth are lost or have to be removed) and, occasionally, result in the development of cysts. PDCs are a frequent dental anomaly, present in 2% to 3% of young people. Read More

Perception of the environment in vertebrates relies on a variety of neurosensory mini-organs. These organs develop via a multi-step process that includes placode induction, cell differentiation, patterning and innervation. Ultimately, cells derived from one or more different tissues assemble to form a specific mini-organ that exhibits a particular structure and function. Read More

"Closed Reduction" Principles Can Manage Diverse Conditions of Temporomandibular Joint Vertical Height Loss: From Displaced Condylar Fractures to Idiopathic Condylar Resorption.

J Oral Maxillofac Surg 2017 Jun 7;75(6):1163.e1-1163.e20. Epub 2017 Feb 7.

Professor Emeritus, University of Zurich, Zurich, Switzerland.

Purpose: The aim of this case series was to describe a modification of the classic "closed reduction" technique to manage unilateral or anterior open bite owing to a loss in vertical height (LVH) caused by several disorders and pathologies other than displaced condylar fractures.

Materials And Methods: The protocol included insertion of an occlusal appliance to increase the height of the premature contact and the width of the open bite, stabilization of the dental arches by rigid arches, and the use, during sleep, of rubber bands in the open bite region to pull the mandible cranially. In addition, when awake, the patient performed physiotherapy exercises to guide the mandible into maximum intercuspation. Read More

Removal of Infected Maxillary Third Molar from the Infra-temporal Fossa by Caldwell Luc Procedure - Rare Case Report with Literature Review.

J Clin Diagn Res 2016 Dec 1;10(12):ZD01-ZD03. Epub 2016 Dec 1.

Professor, Department of Oral and Maxillofacial Surgery, Career Post Graduate Institute of Dental Sciences , Lucknow, Uttar Pradesh, India .

Dentigerous or follicular cysts of odontogenic origin are innocuous benign cysts that are often linked with the crowns of permanent teeth. A dentigerous cyst circumventing permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. In the maxilla or upper jaw region, the impacted teeth are often displaced and/or shift into the maxillary sinus and apart from the nasal septum, mandibular condyle, coronoid process and the palate, to harbour such ectopic eruptions of teeth.
