Treatment for critically impacted maxillary canines: Clinical versus scientific evidence - A systematic review.

Background: Critically impacted maxillary canines are prone to fail to respond to conventional surgical exposure and orthodontic traction. Correct identification of a critical impaction requires enhanced diagnosis modalities and might lead to incorporating alternative surgical strategies in the treatment plan. Predictability of techniques such as apicotomy or tooth autotransplantation is, however, yet to be determined.

Surgically assisted orthodontic alignment of impacted maxillary canines: A retrospective analysis of functional and esthetic outcomes and risk factors for failure.

Introduction: The initial position of an impacted maxillary canine might influence the outcome of surgically assisted exposure and orthodontic alignment. Therefore, the purpose of this study was to evaluate existing correlations between the initial position of the maxillary canine and the outcomes of treatment.

Methods: A retrospective cohort study was designed, containing data of 132 patients (47 males, 106 females; median age at the date of surgical exposure 14 ± 4.

A retrospective long-term pulpal, periodontal, and esthetic, follow-up of palatally impacted canines treated with an open or closed surgical exposure technique using the Maxillary Canine Aesthetic Index.

Introduction: The primary objective of this study was to compare the aesthetic outcome of palatally impacted canines treated with an open or closed surgical exposure technique using the Maxillary Canine Aesthetic Index (MCAI) at least 1 year after debonding. Secondary objectives were set on the periodontal outcome, tooth color, pulpal status, and self-reported contentment.

Methods: The sample of this retrospective study consisted of 53 patients with an average age of 20 years and 7 months at the time of the investigation.

Interventions for impacted maxillary canines: A systematic review of the relationship between initial canine position and treatment outcome.

Background: The objective of this review was to critically assess the existing literature on the relationship between the initial position of impacted canines and treatment outcomes.

Methods: We performed a systematic review of the available literature until February 2020 using the MEDLINE, Cochrane Central, Web of Science and PubMed databases. Prospective and retrospective studies (randomized controlled trials [RCTs], cohort studies, longitudinal follow-up studies) considering impacted maxillary canines that were orthodontically and/or surgically treated, and clearly reporting the initial position using 2D and/or 3D classifications, were included if they assessed at least one of the following: treatment success, treatment duration, number of treatment visits, radiographic outcome, periodontal health, esthetics and/or treatment complications.

Survival and success of autotransplanted impacted maxillary canines during short-term follow-up: A prospective case-control study.

Objectives: This prospective clinical trial aimed to examine the predictability of maxillary canine transplantation as compared to biological canine eruption. Additional objectives were to examine hard and soft tissue outcomes, including aesthetic outcome compared to outcomes with the contralateral canines.

Settings And Sample Population: The sample comprised 17 consecutively transplanted maxillary canines in 17 patients (mean age at surgery, 18 years; range, 11-29 years).

Three-dimensional position of impacted maxillary canines: Prevalence, associated pathology and introduction to a new classification system.

Classification of impacted maxillary canines facilitates interdisciplinary communication. Cone beam computed tomography (CBCT) has proven to be superior for the localization of impacted maxillary canines compared with 2D imaging. The purpose of this study was to retrospectively classify a cohort of impacted maxillary canines, using a new developed 3D classification for impacted maxillary canines that is easy to use and does not require complex analysis of the 3D images.

[Bilateral autogenous transplantation of impacted maxillary canines].

In a fifteen-year-old girl, bilaterally impacted permanent maxillary canines were established. A difficult palatinal placement and an apical deviation were found in both teeth. Surgical exposure of the canines, followed by orthodontic traction was not desirable.

Long-term outcome of autogenously transplanted maxillary canines.

The aim of this study was to determine the long-term outcome of autotransplanted maxillary canines and to investigate the influencing parameters. Seventy-one patients (84 transplanted canines) volunteered to participate in this study. The mean follow-up time was 21 years.

Development and validation of the Maxillary Canine Aesthetic Index.

Aesthetic appraisal is rarely included in the objective assessment of outcome studies of impacted maxillary canines treatment. The present study aimed to validate a new index for assessing the aesthetic appearance of maxillary canines and adjacent soft tissues. The Department of Oral and Maxillofacial Surgery at University Hospitals Leuven.

Development and validation of the autotransplanted maxillary canine radiological index.

The purpose of this study was to propose and validate an index evaluating 2D and 3D radiographic variables of autotransplanted maxillary canines. Setting and sample population are from the Department of Oral and Maxillofacial Surgery at University Hospitals Leuven. Eight oral-maxillofacial surgeons rated 12 autotransplanted maxillary canines and adjacent bone using 11 rating variables.

Autogenous transalveolar transplantation of maxillary canines: a systematic review and meta-analysis.

Background And Objectives: The objective was to systematically review transalveolar transplantation of maxillary canines and the long-term outcome for an average follow-up period of 2 years or more.

Data Collection And Analysis: A systematic review of the currently available literature until December 2017 was conducted, using Medline, Cochrane Central, Web off Science, and PubMed. Articles were screened for 1.

Secondary hyperparathyroidism causing increased jaw bone density and mandibular pain: a case report.

We present the case of a 32-year-old male patient complaining of recurrent mandibular pain for 3.5 years. Panoramic radiography indicated increased cortical density of the mandibular lower border.

Reaching the vertical versus horizontal target position in multi-segmental Le Fort I osteotomy is more difficult, but yields comparably stable results to one-segment osteotomy.

This retrospective cohort study evaluated the postoperative outcomes of preoperatively planned positional changes for Le Fort I osteotomy in 77 patients (average age 26.6 years). Movement relapse and planning accuracy were evaluated by lateral cephalometric analysis, with an average follow-up of 257 days.

Septic arthritis of the temporomandibular joint after acute otitis media in a child.

Septic arthritis of the temporomandibular joint as a complication of acute otitis media is rare in the Western world. This report describes the case of a 7-year-old boy who had pain in his right ear and limited mouth opening, following the onset of acute otitis media. A contrast-enhanced computed tomography scan revealed right-sided mastoiditis and hydrops of the right temporomandibular joint, suggesting septic arthritis.

Medication-related osteonecrosis of the jaw in oncological patients with skeletal metastases: conservative treatment is effective up to stage 2.

There is currently no widespread strategy for treating medication-related osteonecrosis of the jaw (MRONJ), so our aim was to evaluate retrospectively the outcome of a minimally invasive treatment protocol for patients with both MRONJ and cancer. We designed a retrospective cohort study of patients with cancer who had been diagnosed with MRONJ after treatment with denosumab or bisphosphonates given intravenously. Primary outcome measures were improvement in the clinical stage of MRONJ and the time course to its resolution.

The contribution of alliaceous and cruciferous vegetables to dietary sulphur intake.

Despite its importance in many areas of human metabolism, there are no recommended daily intake guide lines for sulphur. It is generally assumed that most dietary sulphur originates from intake of methionine and cysteine. We estimated sulphur intake from food diaries, and validated the results with the use of a duplicate diet analyses.

Case of a cerebral abscess caused by in a subject with periodontitis.

We report the case of a 65-year-old man presenting with generalised seizures after developing a right frontal brain abscess. Stereotactic aspiration and subsequent matrix assisted laser desorption/ionisation time-of-flight analyzer (MALDI-TOF) spectrometry revealed as the only causative anaerobe microorganism. Secondary incision and drainage was required due to neurological deterioration with increased dimensions of the abscess, intracranial pressure and formation of a subdural occipitoparietal empyema.

Numb chin syndrome as a sign of mandibular metastasis: A case report.

Introduction: Metastasis to the oral cavity can be located in both the soft and bony tissues and comprise only 1% of all oral malignancies; however, it is clinically significant because it indicates widespread metastatic disease and an unfavorable prognosis. A numb chin is an important presentation of oral metastasis, but other dental and systemic pathology may be involved.

Presentation Of Case: We present the case of a 54-year-old woman who presented with numb chin syndrome 8 years after a diagnosis of primary breast carcinoma.

Primary intraosseous squamous cell carcinoma of the mandible arising from an infected odontogenic cyst: A case report and review of the literature.

Primary intraosseous squamous cell carcinoma (PIOSCC) derived from a odontogenic cyst is a rare form of odontogenic carcinoma. The incidence of carcinomas arising from odontogenic cysts is particularly uncommon and is reported to occur in 1-2 individuals for every 1,000 cases. The present case describes a 25-year-old man who was initially diagnosed with a chronically infected odontogenic cyst of the mandible.
