OBJECTIVES: This study investigated the association between craniofacial morphology and temporomandibular disorders in adults. The influence of different craniofacial morphologies on painful temporomandibular disorders was also evaluated. MATERIAL AND METHODS: A total of 200 subjects were selected, including 100 with temporomandibular disorders (TMD) and 100 without TMD (control), diagnosed by research diagnostic criteria for temporomandibular disorders. All subjects were submitted to lateral cephalometric radiographs, and classified as brachyfacial, mesofacial, or dolichofacial by Ricketts' analysis...

OBJECTIVES: Dentures are worn by around 20% of the population, yet if they become displaced they may enter the gastrointestinal or respiratory system, sometimes with grave consequences. The aim of this study was to review recent published literature in order to identify the epidemiology of patients and characteristics of swallowed and aspirated dental prostheses, and propose strategies to minimise these risks. MATERIAL AND METHODS: A fifteen year retrospective of published case series and case reports was carried out...

BACKGROUND: Ameloblastoma is a benign odontogenic tumour that may exhibit aggressive biological behaviour with local recurrence and metastasis following initial surgical resection. Surgery is the most acceptable modality of treatment, even if a biological approach is currently on study. We report a case of maxillary ameloblastoma with development of neck and brain metastases after repeated local recurrences. Molecular analysis was performed with the aim to better characterize this neoplasm and its peculiar behaviour...

OBJECTIVES: The dentin matrix servers as a reservoir of growth factors, sequestered during dentinogenesis. The aim of this study was to assess the viability and proliferation of dental pulp stem cells in the presence of dentin matrix-derived non-collagenous proteins and two growth factors; platelet-derived growth factor BB and transforming growth factor beta 1. MATERIAL AND METHODS: The dental pulp cells were isolated and cultured. The dentin proteins were extracted and purified...

OBJECTIVES: The aim of this study was to evaluate the clinical, radiographic and histologic results when a highly purified xenogenic bone (Laddec(®)) was used as grafting material in maxillary sinuses. MATERIAL AND METHODS: In fifteen patients requiring unilateral maxillary sinus augmentation, the grafting procedure was performed with Laddec(®). Forty-two implants were installed after a 6 month healing period. The height of the augmented sinus was measured radiographically immediately after augmentation and postoperatively up to 36 months...

OBJECTIVES: The authors performed a systematic review and meta-analysis to investigate the possible correlation between ambient air pollution and orofacial cleft anomalies in newborns. MATERIAL AND METHODS: A literature search was performed using the PubMed and Google Scholar, using the keywords "air pollution", "cleft lip", "cleft palate", "carbon monoxide", "ozone", "sulfur dioxide", "nitrogen oxide", "nitrogen dioxide", and "aerodynamic diameter". Eight epidemiologic articles met the criteria of correlating either carbon monoxide (CO), ozone (O3), nitrogen oxides (NOx), airborne particulate matter of less than 10 µm in diameter (PM10), or sulfur dioxide (SO2) exposures with clefting of the palate alone, clefting of the lip alone, or clefting of the lip and palate...

OBJECTIVES: Natural head position is recommended to be optimal at cone-beam computed tomography acquisition. For standardization purposes in control of treatment outcome, it is clinically relevant to discuss, if a change of posture from natural head position may have an effect on the pharyngeal airway dimensions and morphology, during computed tomography, cone-beam computed tomography or magnetic resonance imaging acquisition. This was the aim of the present literature review study for purposes of valid evidence, which was hypothesized, to be present...

BACKGROUND: Metastatic tumours to the oral cavity from distant organs are uncommon and represent approximately 1 - 3% of all oral malignancies. Such metastases can occur to the bone or to the oral soft tissues. Almost any malignancy from any site is capable of metastasis to the oral cavity and a wide variety of tumours have been reported to spread to the mouth. METHODS: Careful examination of the oral cavity and a high degree of clinical suspicion as well as a multidisciplinary approach are suggested...

OBJECTIVES: A variety of diagnostic indices in orthodontics have been proposed to help in diagnosis and treatment planning. Pont's Index was established to predict ideal maxillary dental arch width from the sum of mesiodistal widths of four upper incisors. The aim of this study was to assess the applicability of Pont's Index to Lithuanian individuals. MATERIAL AND METHODS: The sample comprised 52 subjects (age range from 18 to 35 years) with normal occlusion. Measurements were obtained directly from plaster casts using a digital calliper...

OBJECTIVES: Temporomandibular disc is a mechanically robust fibrocartilage tissue exhibiting highly elastic compressive, shear, and tensile moduli with structurally dense extracellular matrix that supports functional loading of the joint. The aim of this study was to illustrate structural complexities of the superior and inferior disc surfaces, to demonstrate the robust mechanical ability of the disc as a whole may be due to depth-dependent regional/layered variation, and also to provide characterization data imperative for future tissue engineering efforts focused on restoring function to the joint...

OBJECTIVES: Cone-beam computed tomography in dentistry can be used in some countries by other dentists than specialists in radiology. The frequency of buying cone-beam computed tomography to examine patients is rapidly growing, thus knowledge of how to use it is very important. The aim was to compare the outcome of an investigation on the use of cone-beam computed tomography in Sweden with a previous Norwegian study, regarding specifically technical aspects. MATERIAL AND METHODS: The questionnaire contained 45 questions, including 35 comparable questions to Norwegian clinics one year previous...

OBJECTIVES: To compare the properties of calcium phosphate precipitation on four different bioactive surface preparations and one control surface in the simulated body fluid model with added collagen type I. MATERIAL AND METHODS: Blasted titanium discs were treated with four different surface modifications, alkali and heat, sodium fluoride, anodic oxidation and hydroxyapatite coating. The discs were divided into five groups where one group, the blasted, served as control...

OBJECTIVES: The aim of the present study was to develop a plate to treat mandibular angle fractures using the finite element method and mechanical testing. MATERIAL AND METHODS: A three-dimensional model of a fractured mandible was generated using Rhinoceros 4.0 software. The models were exported to ANSYS(®), in which a static application of displacement (3 mm) was performed in the first molar region. Three groups were assessed according to the method of internal fixation (2 mm system): two non-locking plates; two locking plates and a new design locking plate...

OBJECTIVES: Free fibula flap remains the flap of choice for reconstruction of mandibular defects. If free fibula flap is not possible, the subscapular system of flaps is a valid option. In this study, we evaluated the possibility of dental implant placement in patients receiving a scapular free flap for oromandibular reconstruction. MATERIAL AND METHODS: We retrospectively reviewed 10 patients undergoing mandible reconstruction with a subscapular system free-tissue (lateral border of the scapula) transfer at the University Hospital Zürich between January 1, 2010 and January 1, 2013...

OBJECTIVES: The aim of this study was to verify the impact of dentofacial deformity on quality of life and explore gender and age differences. MATERIAL AND METHODS: The impact of dentofacial deformity (DD) on quality of life was evaluated through questionnaires; Short Form Health Survey (SF36), Oral Health Impact Profile Questionnaire (OHIP), Orthognathic Quality of Life Questionnaire (OQLQ) and a single question answered by a Visual Analogue Scale. RESULTS: Significant differences between male and female patients were observed in domains of OQLQ (oral function, P = 0...
