Experimental evidence of pharmacological management of anchorage in Orthodontics: A systematic review
2015
Introduction: Orthodontic anchorage is one of the most challenging aspects of Orthodontics. Preventing undesired movement of teeth could result in safer and less complicated orthodontic treatment. Recently, several reviews have been published about the effects of different molecules on bone physiology and the clinical side effects in Orthodontics. However, the effects of local application of these substances on the rate of orthodontic tooth movement have not been assessed.Objectives: The aim of this research was to analyze the scientific evidence published in the literature about the effects of different molecules on orthodontic anchorage.Methods: The literature was systematically reviewed …
Zur erweitrten Indikationsstellung der Herbert-Schrauben-Osteosynthese
1995
Since 1984 the typical headless double threaded Herbert/Whipple screw is known in managing scaphoid fractures and scaphoid non-unions. We resume technical, biomechanical and histological aspects to point out advantages and disadvantages of this osteosynthesis. Our case review of 39 patients illustrate the same good results as achieved in treating scaphoid injuries, when using the Herbert/Whipple screw of a larger diameter for expanded indications other than scaphoid fractures, such as humeral- or radial-head fractures, Jones fractures and others.
Odontoiatria di genere: la condizione femminile nella pratica odontoiatrica
2014
Obiettivi: scopo del presente studio è quello di esaminare la condizione femminile in relazione alla professione odontoiatrica, quelle condizioni patologiche orali che possono colpire in particolare il sesso femminile e i trattamenti relativi. Materiali e metodi: oltre alla propria esperienza e al contributo personale, sono state effettuate ricerche sui motori di ricerca scientifica PubMed, Embase e Scopus. Risultati e conclusioni: è stata esaminata la figura della odontoiatra donna e la sua collocazione nell'ambito professionale, nonché le sue caratteristiche lavorative sia in relazione ai pazienti sia in relazione alla propria famiglia. Sono state analizzate poi le più comuni condizioni p…

Shaping ability of Mtwo and Twisted File rotary systems in curved root canals
2012
Objective: To compare the straightening of root canal curvature, the apical transportation, the loss of working length and the working time using two rotary systems. Study design: Sixty buccal root canals with angles of curvature between 30 to 99º were instrumented with Mtwo and Twisted File rotary instruments. A series of pre- and post-operative radiographs were superimposed to determine the straightening of root canal curvature and apical transportation. The loss of working length and working time were also calculated. Results: All data were analyzed by means of the Student´s t-test and Mann-Whitney U-test. No statistically significant differences in the straightening of root canal curvat…
Caliber-persistent Artery: A Case Report
2019
ABSTRACT The caliber-persistent labial artery (CPLA) is a vascular anomaly in which a main branch of the artery penetrates the submucosal area of the lip without loss of caliber. It commonly presents as an elevated soft tissue mass and is often pulsatile on manual palpation. Clinical suspicion is important, given the risk of bleeding, either from slight trauma or accidentally if lack of awareness leads to excision of the lesion owing to an incorrect diagnosis. CPLA should be considered in the differential diagnosis of any lesion affecting the lip, especially to differentiate from mucocele or squamous cell carcinoma. This particular case of CPLA in the upper lip of a girl presents a both unu…
Infezione orale da Human papillomavirus: dalla verruca al carcinoma orale. Epidemiologia, clinica, prevenzione e terapia
2015
Riasunto Obiettivi Prendere in esame l’epidemiologia e le manifestazioni cliniche dell’infezione orale da Human papillomavirus (HPV), con particolare attenzione alle lesioni con potenziale oncologico maligno. Materiali e metodi E stata condotta una revisione sistematica della letteratura finalizzata a descrivere lo stato dell’arte in merito all’infezione da HPV nella mucosa orofaringea e alle relative modalita di trasmissione del virus con particolare riferimento alla possibile contemporanea infezione in sedi anatomiche multiple.

Biological responses to individualized small titanium implants for the treatment of focal full-thickness knee cartilage defects in a sheep model.
2019
Abstract Background The present study aimed to evaluate the functional, radiological and histological outcome of a customized focal implant for the treatment of focal full-thickness cartilage defects in sheep. Methods The study used magnetic resonance imaging data as the basis for construction of the titanium implant using a three-dimensional printing technique. This was then placed on the medial condyle of the knee joint in eight sheep and left in place in vivo over a period of six months. Following euthanasia, the local biological response was analyzed using micro-computed tomography, light microscopy and histological evaluation (International Cartilage Repair Society (ICRS) score). The v…
A study on the reproducibility of cephalometric landmarks when undertaking a three-dimensional (3D) cephalometric analysis
2012
Objectives: Cone Beam Computerized Tomography (CBCT) allows the possibility of modifying some of the diagnostic tools used in orthodontics, such as cephalometry. The first step must be to study the characteristics of these devices in terms of accuracy and reliability of the most commonly used landmarks. The aims were 1- To assess intra and inter-observer reliability in the location of anatomical landmarks belonging to hard tissues of the skull in images taken with a CBCT device, 2- To determine which of those landmarks are more vs. less reliable and 3- To introduce planes of reference so as to create cephalometric analyses appropriated to the 3D reality. Study design: Fifteen patients who h…
Craniomaxillofacial morphology alterations in children, adolescents and adults with neurofibromatosis 1 : a cone beam computed tomography analysis of…
2017
Background Oral manifestations are common in neurofibromatosis 1 (NF1), and include jaws and teeth alterations. Our aim was to investigate the craniomaxillofacial morphology of Brazilian children, adolescents and adults with NF1 using cone beam computed tomography. Material and Methods This study was conducted with 36 Brazilian individuals with NF1 with ages ranging from 4 to 75. The participants were submitted to anamnesis, extra and intraoral exam and cephalometric analysis using cone beam computed tomography. Height of the NF1 individuals was compared to the length of jaws and skull base. The results of the cephalometric measurements of the NF1 group were compared with a control group pa…
