The disease usually progresses rapidly during the first and second decades of life but it is self-limiting and often regresses. Although few orthodontic case reports describing cherubic patients exist, the timing and extent of surgical intervention is controversial.Aim: This present paper aims to review the treatment literature and provide a case report of a patient who underwent orthodontic/surgical management.Methods: The patient presented with severe cherubism in her late teenage years; her main complaint was poor facial and dental appearance. Multiple teeth were missing and those present demonstrated significant preoperative root resorption. Treatment consisted of orthodontic alignment of the upper anterior teeth and a recontouring osteotomy.Results: Confirmed by the patient, the combination approach led to a significant improvement in facial aesthetics and better self-esteem. Tooth movement through the osseous lesions was uneventful and no further root resoption was observed.Conclusion: Orthodontic treatment may be undertaken in those affected by Cherubism even with pre-existing idiopathic root resorption, but patients need to be appropriately informed and consented.","PeriodicalId":55417,"journal":{"name":"Australian Orthodontic Journal","volume":"30 2","pages":"214-20"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32941856","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}

{"title":"Body dysmorphic disorder and orthodontics--an overview for clinicians.","authors":"Marshneil Trista Anthony, Mauro Farella","doi":"","DOIUrl":"","url":null,"abstract":"Introduction: Patients with body dysmorphic disorder (BDD) often seek aesthetic medical treatment including orthodontics to correct their perceived physical defects. When the disorder pertains to the dentofacial region, it is important for orthodontists to be familiar with this condition.Objective: The purpose of this article is to provide an overview of the current knowledge on BDD and its relationship to orthodontics.Method: PubMed, Scopus, Science Direct, and Google Scholar databases were searched for publications relating to BDD and orthodontics. Further articles were sourced from the reference lists of the articles identified through the search.Results: The literature recommends that orthodontic patients suspected of having BDD should be referred to a psychiatrist for a definitive diagnosis and subsequent management. However, this may be difficult to implement in clinical practice. Management by a psychiatrist could include pharmacotherapy and cognitive behavioural therapy. There is still debate as to whether orthodontic treatment should be provided for these patients.Conclusion: As health care workers providing aesthetic treatment to patients, orthodontists should be aware of BDD and its implications. Risks include repeated requests for unnecessary treatment, dissatisfaction with the result and thus potential for litigation. BDD still remains a challenge to diagnose, and further research is needed to determine the appropriate management of orthodontic patients suffering from the disorder.","PeriodicalId":55417,"journal":{"name":"Australian Orthodontic Journal","volume":"30 2","pages":"208-13"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32942493","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}

{"title":"The effects of denervation and formoterol administration on facial growth.","authors":"Brendan Fitzpatrick, Michael Woods, Gordon Lynch, David Manton","doi":"","DOIUrl":"","url":null,"abstract":"Objective: To identify and demonstrate possible alterations of skeletal structures which might follow either unilateral surgical denervation of the masseter muscle, unilateral intramuscular injection of formoterol directly into the masseter muscle, or intramuscular formoterol injection after surgical denervation.Materials and methods: Male Sprague Dawley rats (N = 16; four weeks of age) were prepared as four groups: 1. surgical sham + saline injection into the masseter muscle (sham); 2. surgical denervation of the masseter muscle only (den.); 3. surgical denervation of the masseter muscle plus intramuscular formoterol injection into the affected muscle (den.+form.); 4. intramuscular formoterol injection into the masseter muscle only (form.). The specimens were submitted for CT examination, the skulls and hemimandibles were photographed and measurements of craniofacial bones were made.Results: In this relatively small sample, comparisons between non-experimental and experimental sides revealed differences, both within the groups and for the same measurements between groups, with the den. and den.+form. groups showing the most change. Relative increases in the gonial angle shown in these groups occurred bilaterally, with the change on the experimental side always greater in magnitude than the change on the contralateral side.Conclusions: Surgical denervation of the masseter muscle leads to an alteration in the size and shape of the skeletal structures close to the zygoma and the mandible. The intramuscular injection of formoterol into denervated masseter muscle seems to limit this skeletal alteration after surgical denervation.","PeriodicalId":55417,"journal":{"name":"Australian Orthodontic Journal","volume":"30 2","pages":"161-8"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32942487","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}
