Aspiration was negative initially while, it showed serous blood the second time. Radiograph featured a unilocular radiolucency extending from left mandibular first premolar to right mandibular first molar with evidence of inter-radicular scalloping. With all these clinical and radiographic features we could arrive at a provisional diagnosis of traumatic bone cyst. A complete surgical excision followed by curettage of the cystic cavity was performed. The excised specimen was sent for histopathological evaluation. Histology showed presence of dense connective tissue, chronic inflammatory cell infiltrate and a normal bone with no epithelial lining. *Correspondence to: Balamurugan R, MDS, Oral and Maxillofacial Surgeon, RYA COSMO Foundation Hospital, India, E-mail: bala100192@gmail.com","PeriodicalId":10996,"journal":{"name":"Dental, Oral and Maxillofacial Research","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72560465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improved characterization of these rare variants is needed, as improper diagnosis may lead to inappropriate or delayed treatment. A case series of patients with lingual horns diagnosed and treated at two academic hospitals from 2008 to 2019, was performed along with a literature review. We have diagnosed and inventoried seven lingual mucosal horns. The clinical description reveals a unique white overgrowth located on the dorsal surface of the tongue, delevoping at expense of the filiform papillae, without any preferential site but always located forward of the V-shaped line. The lesions are firm but remain nevertheless flexible, movable, a few millimeters high, with a conical shape. The lingual mucosal horn is a conical overgrowth whose occurrence is extremely rare. The lingual mucosal horn is a non-viral papilloma, and differs from the cutaneous variant. *Correspondence to: Frédérick Gaultier, DDS, PhD, Henri Mondor Hospital, Oral Medecine and Oral Surgery Department, ParisDescartes University, Ilede France, France and Laboratory of Molecular Oral Pathophysiology, INSERM 1138, Paris, France, E-mail: frederick.gaultier@parisdescartes.fr","PeriodicalId":10996,"journal":{"name":"Dental, Oral and Maxillofacial Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78811055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This technique consisted in making bracket-positioning guide on the cast manually by using McLaughlin method [2], with the aim to align, leveling teeth and marginal ridges [1]. It also allowed to control the procedural variables (e.g. tray stability, flushes, curing time, etc.), standardizing indirect bonding technique for the routine and effective use of indirect bonding procedure. Despite the described advantages of this technique, the accuracy in bracket positioning was influenced by manual skills of clinicians in tracing the bracket-positioning guide on the cast, and by the ability of the trained technician in positioning the brackets on the cast precisely. The advent of digital orthodontics, in particular digital impression, simplified the process to have a digital model by dedicated CAD software, allowing analysis, measurements, virtual setup, and digital bracket positioning. Since the first paper on prototyped transfer tray published in 2006 [4], several digital systems allowed to transfer virtual bracket position by using a prototyped gig/tray, in which the real brackets were inserted, then transferred on the teeth by using lightcuring bonding with some limitation in the clinical stage (eg. Flushes, light curing process). On the contrary, as reported in 2012 [1], the use of customized bracket base, by pre-dosed light-cured adhesive, showed two main clinical advantages: (1) The customised bracket base respected the surface anatomy reducing the errors related to adhesive excess and flushes; (2) Self-curing indirect bonding used in the clinical stage took just 4 minutes and needed no attention from the operator, whereas the indirect light-curing and bonding took 30 seconds for each bracket from first molar to last molar, requiring also active attention all the time. As reported in the previous paper [1], one advantage of that technique was the possibility to be integrated with CAD/CAM procedure; since, to our knowledge, there are no papers showing CADCAM system able to transfer the virtual bracket position with a predosed customized bracket base.

Oral care, aiming to enhance patients’ QOL, is likely to be effective to address problems specific to pediatric cancer patients. This study examined the effects of specialized oral care to improve such patients’ oral environments and QOL. Methods: Pediatric cancer in patients receiving chemotherapy and radiotherapy in our University Hospital Medical Center for Children, for whom specialized oral care had been requested, were studied. The contents of the specialized oral care for them included: brushing guidance, dental tartar removal, and oral moistening, gargling guidance, and/or dental treatment in accordance with the type of oncological treatment. Before and after care, oral environments were assessed using an original sheet, while measuring oral moisture and bacterial levels, and conducting a questionnaire survey on patient satisfaction. The assessment sheet consisted of Revised Oral Assessment Guide (ROAG) items, in addition to those regarding halitosis, the mouth-opening degree, dental condition, changes in the gustatory sense, and oral mucositis. For the questionnaire survey, the Child Perceptions Questionnaire (CPQ) 8-10 sheet was used to comprehensively evaluate the pediatric patients’ oral health-related QOL. Results: The mean oral assessment score decreased after care, while there were no changes in the oral moisture or bacterial level. Regarding the questionnaire, the mean overall score decreased after care. Decreases were also observed in the score for each question with increases in the number of intervention sessions. Conclusion: The maintenance and improvement of oral hygiene through specialized oral care are important to appropriately treat late-stage complications and provide health management education for pediatric cancer patients. In this study, specialized oral care was effective to improve such patients’ QOL. *Correspondence to: Toshiro Yamamoto, Department of Dental Medicine, Kyoto Prefectural University of Medicine, Graduate School of Medical Science, 465, Kajii-cho, Kawaramachi-Hirokoji, Kamigyo-ku, Kyoto, 602-8566, Japan, Tel: 81752515641; Fax: 81752515641; E-mail: yamamoto@koto.kpu-m.ac.jp","PeriodicalId":10996,"journal":{"name":"Dental, Oral and Maxillofacial Research","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85603821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even if recommendations are proposed by national health agencies, it is still a fairly neglected area. A facility in Montpellier, South of France, has been working for several years to improve patients’ oral health and a caregiver is specially involved in this aspect. This article is about evaluating the activity of this facility on oral health and identifying the opportunity to use teledentistry. We realized a retrospective analyse of patient medical files for a period of 58 months. We identify that, among the 415 appointments to the dentist, only 3% have been performed under general anaesthesia. Teledentistry could decrease this number by 25%. Rather than saving money and time to the facility, teledentistry could also save energy and time from the patients and it is priceless. Teledentistry should be implemented to be officially evaluated in this type of facility, but it seems to be a good public health tool, on the theoretical aspect. *Correspondence to: Giraudeau Nicolas, Public health and telemedicine department, dental department, University hospital of Montpellier, 547, Avenue du Pr Jean-Louis Vialla 34080 Montpellier, France Montpellier, France, E-mail: nicolas.giraudeau@umontpellier.fr","PeriodicalId":10996,"journal":{"name":"Dental, Oral and Maxillofacial Research","volume":"136 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89491079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
