Methodological quality and outcome of systematic reviews reporting on orthopaedic treatment for class III malocclusion: Overview of systematic reviews
No full textObjectives: The aim of this overview of systematic reviews was to investigate methodological quality and outcome of current systematic reviews (SRs) reporting on orthopaedic treatment for class III malocclusion. Materials and methods: Computerized and manual searches were performed in Medline, Google Scholar, Cochrane Library, Embase, LILACS, SciELO, American Journal of Orthodontics and Dentofacial Orthopaedics, Angle Orthodontist, European Journal of Orthodontics, Journal of Orthodontics, Conference abstracts and Grey literature. No restrictions were set on language or date of publication. The search covered the starting date of the relevant databases until 30 April 2015. MeSH terms and free-text terms included ‘malocclusion’, ‘Angle class III’, ‘orthodontic appliances’, ‘functional’, facemask, review and meta-analysis. Screening of eligible studies, assessment of the methodological quality of the SRs and data extraction were conducted in duplicate and independently by two reviewers. Methodological quality was assessed using AMSTAR (assessment of multiple systematic reviews). Results: A total of 222 studies were retrieved and after removal of duplicates, irrelevant studies, literature reviews and surgical approach treatments, 14 SRs and/or meta-analyses were included for qualitative synthesis. Mean AMSTAR score was 7.7/11 with a range of 3-10. There was evidence to demonstrate that face mask therapy can move the maxilla forward whilst causing a backward rotation of the mandible and increased facial height. There was also some evidence of mandibular growth retardation with chin cup therapy. Conclusions: Orthopaedic appliances can improve a class III malocclusion in growing patients over the short-term; however, each appliance has a characteristic effect on the underlying skeletal pattern
Salivary gland biopsy: a comprehensive review of techniques and related complications
No full textOBJECTIVE: This study proposes a revision of the literature on the current techniques employed in salivary gland biopsy.
METHODS: A systematic review of the literature between January 1990 and January 2010 was conducted using MEDLINE, Embase and the Cochrane Central Register of Controlled Trials. The search terms were: 'biopsy AND parotid AND Sjögren'; 'biopsy AND sublingual salivary gland AND Sjögren'; 'biopsy AND minor salivary gland AND Sjögren'; 'biopsy AND labial salivary gland AND Sjögren' and 'biopsy AND salivary glands AND connective disorders'.
RESULTS: No study reporting submandibular salivary gland biopsy was found; 3 studies reported sublingual salivary gland biopsy; 1 study reported palate biopsy; 4 studies reported parotid gland biopsy and 21 studies reported minor salivary gland biopsy.
CONCLUSION: Biopsy of salivary glands must be performed as last investigation and only when the other items are not complete enough to satisfy the diagnosis. The knowledge of complications and sequelae may be useful in order to minimize the risk

Oral self-injuries: Clinical findings in a series of 19 patients.
No full textObjectives: Self-injury (SI) is defined as a behavioral disturbance consisting of a deliberate harm to one's own body without suicidal intent, it is not uncommon and ranges in severity from simple nail-biting to more extreme forms of self-mutilation. The head neck region may be the target of such lesions. SI is associated with several medical conditions, of which it can represent the first clinical sign. Aim of this paper is to describe a series of oral SI, giving special emphasis to the clinical findings, etiology and the management of lesions. Material and Methods: A total of 19 patients with oral SI were prospectively examined; attention was paid to the occurrence and characterization of oral lesions. The management of the lesion also varied depending on the patient medical history, on the etiology of the psychiatric behavior, and on the severity, frequency, and method of inflicting injury. Periodic examinations were performed (after two weeks, three months and six months) and registered. Results: All the patients healed gradually and healing was conditioned by the disease underlying. The treatment consisted of behavior modification in 11 cases, pharmacological treatment in 11 cases, psychotherapy in 2 cases, mouth guard in 9 cases, surgery in 2 cases, extractions in 1 case. Conclusions: Oral SI are uncommon in the clinical practice. They may be associated with a known disease or may be the consequence of this, but often they may be the first sign of a psychiatric disorder
Dento-skeletal class II malocclusion in the mixed dentition period: Treatment with the aid of miniscrews
No full textObjectives: To demonstrate how class II malocclusion can be corrected with the aid of miniscrews, without the patient's cooperation, by exploiting the growth differential to improve skeletal relationships. Materials and methods: Miniscrews were used to provide anchorage during multibracket treatment of dentoskeletal class II malocclusion in a patient with mixed dentition (vertebral bone age CS1). Results: Dentoskeletal class II malocclusion was corrected rapidly - without the patient's cooperation - using upper-arch bonding alone. Conclusions: Miniscrews can be a useful aid for achieving rapid, early correction of dentoskeletal class II malocclusion in noncompliant patients. © 2012 Elsevier Srl. All rights reserved
Early treatment of an ectopic premolar to prevent molar-premolar transposition.
No full textOrthodontic treatment is planned on an individual, case-by-case basis after thoroughly considering the patient's overall facial and dental characteristics, the expected duration of treatment, costs, patient preferences, and the orthodontist's experience. This article reports the treatment of a patient with a maxillary premolar-molar transposition in the permanent dentition that was successfully managed with orthodontic treatment. A girl, aged 10 years 2 months, came for treatment with an ectopic maxillary left premolar. Radiographic analysis indicated a developing complete transposition of the maxillary left premolar. The patient was treated with extraction of the deciduous molar and surgical exposure and ligation of the premolar. Eruption was properly guided, and the correct order of the 2 teeth was restored in the arch. This challenging treatment approach is described in detail, including the mechanics used to align the ectopic premolar. Early treatment can, in many cases, prevent a molar-premolar transposition
