Endodontic Output in Public Healthcare under Different Instrumentation Techniques: A Quantitative and Qualitative Study

Objective: To evaluate output of endodontic in oral public healthcare by analyzing differences in instrumentation techniques, quantitative and qualitatively. Material and Methods: Endodontic services were differentiated by instrumentation techniques: hand techniques with stainless steel instruments (SS) or rotary using NiTi rotary instruments. Secondary data on the productivity of 2011 were obtained from the information system. Student’s t and Mann-Whitney tests were used. Qualitative data were based on semi-structured interviews, direct observation and field diary. Results: Service I employed SS hand techniques, service II used both techniques, while NiTi rotary system was used in service III. Statistically significant differences were observed in total endodontic productivity, with I presenting more productive results than II (p=0.001) and III (p=0.009); III presenting more productive results than II (p<0.001). Comparisons of endodontic treatment types revealed that I performed more multiradicular tooth treatments than did II and III (p=0.005), and III performed more treatments on biradicular teeth than did I and II (p=0.002). Qualitative analyses were divided into themes: “perceptions of the service” and “perceptions of the employed instrument”. Conclusion: Professional experience and high productivity per hour can be a differential; the use of rotary instrumentation can be useful in solving unmet demands. Perception of endodontists showed that chosen endodontic technique influenced job satisfaction and lack of integrality of the treatment is a problem in secondary care

Vaccination against hepatitis b virus: are Italian medical students sufficiently protected after the public vaccination programme?

The development of a vaccine against hepatitis B virus (HBV) has been a major achievement in terms of prevention of HBV infection. For the present study, we analysed the long-term immunogenicity and effectiveness of HBV vaccination among healthcare students with different working seniorities.Background: The development of a vaccine against hepatitis B virus (HBV) has been a major achievement in terms of prevention of HBV infection. For the present study, we analysed the long-term immunogenicity and effectiveness of HBV vaccination among healthcare students with different working seniorities. Methods: A cross-sectional study of undergraduate and postgraduate students attending the Medical School of the Second University of Naples was conducted between September 2012 and December 2014. HBV serum markers were determined and multivariate logistic regression analysis was used to identify factors associated with the level of long-term immunogenicity. Results: Of the 2,932 subjects evaluated, only 33 (1.1 %) declared no history of vaccination. All vaccinated subjects were HBsAg/anti-HBc negative, 459 of which had an anti-HBs titre <10 IU/L. The latter were younger, more likely to be attending a healthcare profession school (i.e., dental hygienists, nursing, paediatric nursing, radiography and midwifery) than a medical school (at either undergraduate or postgraduate level) and more likely to have been vaccinated in infancy. Conclusion: The results of this study suggest that assessment of HBV serum markers in workers potentially exposed to hospital infections is useful to identify small numbers of unvaccinated subjects or vaccinated subjects with low antibody titre, all of whom should be referred to a booster series of vaccinations

The use of antimicrobial photodynamic therapy in the successful management of an invasive cervical resorption class 4: A case report with five years follow-up

A 41-year-old male with a dental history of invasive cervical resorption (ICR) was initially treated with a surgical endodontics approach and secondly with antimicrobial photodynamic therapy (aPDT) along with endodontic retreatment. The use of aPDT was essential to promote bacterial reduction in the resorption defect. Combining these techniques allowed for clinical, radiographic, and tomographic success after five years of follow-up
