Oral mucosal lesions and risk habits among men in an Italian study population
2001
A randomly selected study population of 118 male subjects (> or = 40 years) living on the Mediterranean island of Pantelleria (southwest of Sicily, Italy) was examined for the presence of oral mucosal lesions, with particular emphasis on the early diagnosis of oral precancerous and cancerous lesions. The study population was interviewed for socioeconomic and behavioural information, and clinically examined using WHO criteria. The prevalence of oral mucosal lesions observed, and data obtained about oral hygiene, tobacco smoking, alcohol drinking and exposure to actinic radiation, were analysed. Alcohol drinking was the most common habit in the study population (73%), followed by tobacco smok…
Is periapical surgery follow-up with only two-dimensional radiographs reliable? A retrospective cohort type sensitivity study
2021
Background Two-dimensional (2D) radiographic techniques are commonly used for assessing lesion prognosis after endodontic surgery. The present retrospective cohort study analyzes the sensitivity and ability of different radiographic techniques in obtaining area and volume measurements of periapical lesions. Material and Methods Preoperative and follow-up (6-48 months) periapical and panoramic radiographs (index test) and cone-beam computed tomography (CBCT) images (reference standard) were selected from an endodontic microsurgery database. Sensitivity was analyzed independently by two examiners. The areas of the 2D radiographic images and CBCT volumes were studied using Itk-Snap software an…
Attitudes of Italian dental and dental hygiene students toward tobacco-use cessation
2010
Objective: The aim of this study was to investigate the smoking habits of Italian dental and dental hygiene students and to assess their knowledge on the health effects of cigarette smoking and their attitudes toward tobacco-use cessation (TUC) in dental practice. Materials and methods: Data was collected from 220 students attending the Dental and Dental Hygiene Schools (DS and DHS, respectively) at the University of Palermo (Italy). Results: The percentage of smokers amongst DS and DHS students was similar (32.78% vs. 32.5%) with 67.77% of DS students and 77.5% of DHS agreeing that the damages to health caused by smoking were covered in their didactic course work. A high percentage of DS (…
High prevalence of oral potentially malignant disorders and risk factors in a semi-urban brazilian city: a population-based cross-sectional study
2021
Background Oral Potentially Malignant Disorders (OPMDs) are defined as lesions with a greater likelihood of progressing to cancer. Population-based studies that evaluate the prevalence of OPMDs are scarce in Brazil. The aim of the present study was to determine the prevalence of OPMDs and associated risk factors in a semi-urban Brazilian population. Material and Methods This is a cross-sectional study, whose universe included individuals aged 40 years or older residing in a medium-sized city of northeastern Brazil. Data collection was divided into two steps: interview and oral examination. The outcome variable was the presence of OPMDs. The predictor variables were sociodemographic characte…
Yliopistouudistuksen diskursiivinen rakentuminen Jyväskylän yliopistoyhteisössä 2009-2010
2012
Pro gradu -tutkielmassani tarkastelen Suomen uudelle yliopistolaille (2009) annettuja ristiriitaisia merkityksiä Jyväskylän yliopistoyhteisössä. Yliopistouudistus toi mukanaan merkittäviä taloudellisia ja ideologisia muutoksia suomalaiseen yliopistokenttään, ja siksi muutoksista on kiistelty paljon. Keskusteluissa on kuitenkin luonnehtinut ”yliopistouudistus hyvänä vs. pahana” -asettelu, joka ei ole paras mahdollinen tapa lähestyä uudistuksen jälkiteollisia syitä ja moninaisia seurauksia. Diskurssintutkimuksen näkökulmasta yliopistouudistuskeskustelut ovat kielellisten ”totuuksien” luomista siitä, mikä on suomalaisten yliopistojen tarkoitus nyky-yhteiskunnassa. Näillä ”totuuksilla” eli ylio…
Ocena zależności pomiędzy objawami klinicznymi przewlekłej niewydolności żylnej i ultrasonograficznymi cechami refluksu żylnego u chorych z żylakami …
2001
Wstęp: Celem badania było porównanie objawów klinicznych przewlekłej niewydolności żylnej ze stopniem nasilenia refluksu żylnego, stwierdzanym w badaniu ultrasonograficznym u chorych z żylakami kończyn dolnych. Materiał i metody: Badaniu poddano 50 chorych — 100 kończyn dolnych: 23 kończyny bez żylaków (w tych przypadkach żylaki występowały na drugiej kończynie), 13 kończyn z żylakami, które nie powodowały dolegliwości, 49 kończyn z żylakami, którym towarzyszył obrzęk i/lub dolegliwości bólowe, 15 kończyn z żylakami z towarzyszącymi zmianami skórnymi (z wyjątkiem owrzodzenia). Przeprowadzono ultrasonograficzną (USG Duplex-Doppler) ocenę refluksu w żyłach: udowej, podkolanowej, piszczelowej …
Tekijänoikeuslaki eduskunnan käsittelyssä : digitaalisten oikeuksien hallinnan teknologiat päätöksenteon kohteena
2007
Tässä tutkielmassa tarkastellaan digitaalisten oikeuksien hallinnan teknologioita eduskunnan päätöksenteon kohteena. Tutkimusongelmina selvitän ensiksi kuluttajan ja tuottajan intressejä digitaalisten oikeuksien hallinnan teknologioilla (engl. digital rights management, DRM) suojattuun aineistoon. Toisena tutkimusongelmana selvitän miten ja mitkä kuluttajien ja tuottajien intressit politisoituvat kansanedustajien argumentaatiossa, sekä kolmanneksi tarkastelen miten kansanedustajat politikoivat, toimivat poliittisesti säätäessään tekijänoikeuslain. Ensimmäisen tutkimuskysymyksen aineistona ovat tieteelliset artikkelit, toisen ja kolmannen tutkimuskysymyksen aineistona ovat tekijänoikeuslakik…
Comparison of the whole slide imaging and conventional light microscopy in the grading of oral epithelial dysplasia: a multi-institutional study
2020

No. of bitstreams: 0 Previous issue date: 2021-01-01 Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Background: Whole Slide Imaging (WSI) is an alternative method to light microscopy (LM). However, few studies have compared the diagnostic agreement between WSI and LM, especially to grade oral epithelial dysplasia (OED). The purpose of this study was to evaluate the variability in grading OED by the World Health Organization grading system, using WSI and conventional LM, and to investigate whether the access to clinical information, and psychologic or phy…

Oral leukoplakia, a clinical-histopathological study in 412 patients
2020
Background A retrospective clinical-histopathological study was made of the evolution of oral leukoplakia over time, staging the disease according to the classification of van der Waal. Material and Methods A study was made of 412 patients with oral leukoplakia, analyzing the corresponding clinical factors and histopathological findings; assessing associations between the different clinical presentations and epithelial dysplasia; and evaluating the factors influencing malignant transformation of the lesions. Results Clinically, homogeneous presentations were seen to predominate (n = 336, 81.6%), while histologically most of the lesions exhibited no dysplastic changes (n = 271; 65.7%). Stage…
