In this retrospective study we investigated the long-term survival of autotransplanted premolars and molars with incompletely developed roots. The presence of the transplanted teeth and their outcome after autotransplantation was ascertained from clinical and radiographic evaluation by a maxillofacial surgeon or dentist. Kaplan Meier survival curves were estimated for the total population and for the two groups (premolars and molars).Fifty-one patients with 74 transplanted teeth were included, and...
Abstract Objectives Two‐part abutments consist of titanium base and ceramic coping. Their long‐term success is largely determined by the mechanical stability. The aim of the present study was to investigate the retention forces of two‐part implant abutments. The study included zirconia and lithium disilicate ceramics copings, with different surface treatments and resin‐based luting agents. Material and Methods The analysis of retention forces was based on a total of 70 test specimens. Seven...
The junctional epithelium (JE) is a specialized portion of the gingiva that seals off the tooth‐supporting tissues from the oral environment. This relationship is achieved via a unique adhesive extracellular matrix that is, in fact, a specialized basal lamina (sBL). Three unique proteins – amelotin (AMTN), odontogenic ameloblast‐associated (ODAM), and secretory calcium‐binding phosphoprotein proline‐glutamine rich 1 (SCPPPQ1) – together with laminin‐332 structure the supramolecular organization of...
Abstract Background Oral lichen planus is a chronic T‐cell mediated inflammatory disease, which is associated with increased risk of developing oral squamous cell carcinoma. Epithelial to mesenchymal transition is a physiological phenomenon occurring during growth and organogenesis, but it has also an important role in tumorigenesis. In the present work, we studied the expression of known epithelial to mesenchymal transition markers in oral lichen planus. Methods In total, 54 oral lichen...
Abstract Lichenoid granulomatous reaction can be subcategorized into lichenoid granulomatous dermatitis or lichenoid granulomatous stomatitis. It is described in the literature as demonstrating a band‐like lichenoid infiltration with clusters of histiocytic or granuloma formation. In this study we presented a large case series of lichenoid granulomatous stomatitis including demographics, histological features, and subcategories and compared findings with current literature. Methods and Materials...
Treatment for ranula is classified into three categories depending on how the leaking saliva is managed: removal of the leaking site by intraoral or transcervical resection of the sublingual gland; formation of a drainage tract through the wall of the pseudocyst by micromarsupialisation or marsupialisation; or sealing of the site of the leak by inducing fibrosis with a sclerosing agent. Resection of the sublingual gland is probably the option most likely to be curative for both oral and plunging...
As training in microvascular surgery often involves the use of live animals, it is important that such a practice is regularly revisited and justified, particularly in the context of emerging training strategies such as virtual simulation. This systematic review was therefore designed to assess the ongoing need for their use over other methods. A search of PubMed and MEDLINE using the major MeSH terms: anastomosis, surgical vascular procedures, microsurgery, and training, yielded 1386 titles from...
Unilateral soft palate paralysis is rare. No cases of unilateral soft palate paralysis with associated velopharyngeal insufficiency (VPI) secondary to minor blunt neck trauma have been reported to date. This case details the presentation of a man with isolated unilateral soft palate paralysis and associated velopharyngeal insufficiency following a collision with an opponent when playing soccer.
Radial forearm free flap reconstruction for head and neck cancer is very common, and it is widely considered a workhorse flap. Although this flap has a relatively reliable anatomy, surgeons need to be aware of possible anatomical variations and how to deal with them. This paper presents the cases of two patients who underwent oral reconstruction, in whom anomalies of the radial artery were identified while raising a radial forearm free flap. Case 1 demonstrates the dominant branch of the radial artery...
Chronic vascular rejection characterized by the myointimal proliferation of smooth muscle cells that progressively obstruct the arterial graft lumen may become the main cause of long-term graft loss in vascularized composite allotransplantation (VCA), as observed in solid organ transplantation. As such, new diagnostic tools are required. The objective of this study was to evaluate the usefulness of flow magnetic resonance imaging (MRI) in the qualitative and quantitative monitoring of VCA in three...
This study examined the influence of bone thickness on the split pattern of sagittal ramus osteotomy at 62 sites using Dolphin 3D software. Four measurements of thickness were obtained from the preoperative computed tomography scans: measurement A was made 1.5mm above the lingula, using the coronal and sagittal planes; measurement B was made at the same height as measurement A and 1mm from the anterior border of the ramus; measurement C was obtained 5mm distal to the last molar and 5mm below the...
The study assessed risk factors for traumatic dental injuries (TDI) using experiences along the life course. A retrospective longitudinal study, including historical clinical data, was conducted on 16‐yr‐old pupils in western Norway. All first‐grade pupils born in 1997 and attending public high schools were invited to participate (n = 5,184). Participants responded to an electronically administered closed‐ended questionnaire (39.6%, n = 2,055). Information on the occurrence of TDI and events during...
