    *Dossiê* Towards a Conversational Public Administration? Public Services, Chatbots, and New Organisational Challenges for Local Authorities: public services, chatbots, and new organisational challenges for local authorities

    No full text
    Introduction: In a context where public administrations are increasingly required to rethink their organizational and relational models in light of digital transformation, artificial intelligence (AI) emerges as a promising lever for innovation in local public services. In particular, the intersection between AI and institutional communication opens up new scenarios for the interaction between administrations and citizens, raising critical questions about efficiency, accessibility, and trust. Objective: This study explores the organizational challenges and communication practices associated with the introduction of AI in Italian local governments, with a specific focus on the deployment of chatbots and the use of AI tools by public employees. Methodology: The research adopts a qualitative methodology, based on 26 in-depth interviews with managers, officials, and heads of ICT and communication departments in public entities across three Italian regions (Lombardy, Emilia-Romagna, and Lazio), selected based on their level of digital maturity. Results: The findings reveal a heterogeneous and still experimental landscape: while there are promising opportunities in terms of automation and service improvement, structural weaknesses persist, particularly concerning organizational fragmentation, data governance, and the shortage of internal competencies. The use of chatbots in communication processes is widely viewed as potentially beneficial, yet its effectiveness is heavily dependent on the quality of informational infrastructures and the ability of AI to support trust-based relationships. Conclusion: Ultimately, the study offers a reflection on the conditions necessary for the effective integration of AI into the broader eGovernment framework.Introduzione: in un contesto in cui le pubbliche amministrazioni sono sempre più chiamate a ripensare i propri modelli organizzativi e relazionali alla luce della trasformazione digitale, l’intelligenza artificiale (IA) emerge come una leva promettente per l’innovazione nei servizi pubblici locali. In particolare, l’intersezione tra IA e comunicazione istituzionale apre nuovi scenari per l’interazione tra amministrazioni e cittadini, sollevando questioni critiche riguardo a efficienza, accessibilità e fiducia. Obiettivo: questo studio esplora le sfide organizzative e le pratiche comunicative associate all’introduzione dell’IA nelle amministrazioni locali italiane, con un focus specifico sull’impiego di chatbot e sull’uso di strumenti di IA da parte dei dipendenti pubblici. Metodologia: la ricerca adotta una metodologia qualitativa, basata su 26 interviste in profondità con dirigenti, funzionari e responsabili dei dipartimenti ICT e di comunicazione in enti pubblici di tre regioni italiane (Lombardia, Emilia Romagna e Lazio), selezionati in base al loro livello di maturità digitale (Indice DESI Regionale, Politecnico di Milano, 2022). Risultati: i risultati rivelano un panorama eterogeneo e ancora sperimentale: sebbene vi siano opportunità promettenti in termini di automazione e miglioramento dei servizi, persistono debolezze strutturali, in particolare riguardo alla frammentazione organizzativa, alla governance dei dati e alla carenza di competenze interne. L’uso dei chatbot nei processi comunicativi è ampiamente percepito come potenzialmente vantaggioso, ma la sua efficacia dipende in larga misura dalla qualità delle infrastrutture informative e dalla capacità dell’IA di sostenere relazioni basate sulla fiducia. Conclusione: lo studio offre una riflessione sulle condizioni necessarie per l’efficace integrazione dell’IA all’interno del più ampio quadro dell’eGovernment.In a context where public administrations are increasingly required to rethink their organizational and relational models in light of digital transformation, artificial intelligence (AI) emerges as a promising lever for innovation in local public services.

    Full text link
    Aim: This study aimed to evaluate the symmetry of root canal number and morphology between opposite premolars and molars in each jaw using Cone-Beam Computed Tomography. Methods: 100 CBCT images of patients aged 18-65 were analyzed for diagnostic or therapeutic purposes. 96 premolars and mandibular molars, as well as 98 premolars and maxillary molars, were examined separately by two endo- and radiologists. Parameters such as canal numbers and root numbers in each root, and shape, and morphology of the canals were evaluated using NNT software. The symmetry of similar teeth in each jaw was also determined. Results: This study found that most mandibular premolars have one root and one canal with a type I Vertucci, while there are two roots and three canals in mandibular molars. Mostly, there is one root, two canals, and a type IV canal in maxillary premolars, while maxillary molars have three roots and three or four canals. The jaws have symmetry in terms of canal type, root numbers, and canal numbers. The mandible has greater symmetry than the maxilla in all cases. Conclusion: Assessing the symmetry of the canal numbers and premolars and molars morphology on both sides of each jaw using CBCT showed a significant correlation on both sides particularly between the first and second premolars and second molars, which can help dentists in comprehending root canal treatments and enhancing outcomes

    Transverse maxillary discrepancy, mandibular skeletal retrusion, and increased lower anterior face height have been recognized as frequent abnormalities in growing individuals, despite the paucity of available data. Aim: This research looked at the relationship between treatment planning and Control of Vertical Dimension (CVD) effectiveness in orthopaedic and orthodontic therapy (OT). Methods: We searched full-text publications in PubMed, Web of Science, Scopus, Embase, Google Scholar, and ScienceDirect databases from 1970 to 2024. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) quality scale was used for the critical selection of the studies. Results: We identified 43 articles, of which 28 were included in the review. Also observed that a strong and positive relation was established for the two parameters of CVD and OT for both growing subjects. Conclusion: We can suggest from our study that rapid maxillary expansion (RME) can be used as an aid for the control of vertical dimension estimation

    Full text link
    Aim: Oral lichen planus (OLP) is a relatively common chronic inflammatory mucocutaneous disease in middle-aged individuals that often affects the oral cavity, and its prevalence has increased in recent years. The aim of this study was, in addition to examining the epidemiological information on OLP, to investigate the referral pattern, the chief complaint of patients, and the clinical manifestations of the diseases in OLP patients in northeastern Iran. Methods: The records of OLP patients referred to the Department of Oral and Maxillofacial Diseases at the Faculty of Dentistry of Mashhad University of Medical Sciences in Iran from 2004 to 2017 were examined. The data were collected from the records by completing a checklist that included age, sex, education, place of residence, location and type of lesion (reticular, papular, plaque-like, atrophic, erosive and bullous), the patient’s main complaint, referral pattern, and referral time. The data were analyzed using SPSS 22 and Chi-squared, Fisher’s exact, and Kendall’s Tau-b tests were used for data comparison. Results: The records of 504 OLP patients were evaluated. 68.3% of the patients were female and 31.7% were male with a mean age of 50.10 ± 13.99 years. 32.3% of the cases were referred by general dentists and 26% by specialist dentists. The most common area of involvement was the buccal mucosa (84.1%) and the most complaint was the burning sensation (59.5%). The patient complaints were significantly associated with the clinical manifestations of erosive and non-erosive lesions (P <0.001). In addition, dysplasia was observed in 4.6% of the patients with biopsy (in subsequent biopsy). Based on the history of treatment, the number of patients with skin involvement was significantly higher than that of patients without skin involvement (P = 0.045). Furthermore, 43.8% of patients with skin involvement referred within 6 to 12 months, which was significantly higher than the number of patients without skin involvement (P = 0.016). Here, the most referrals were made by general dentists and the most common clinical manifestation was erosive (nonkeratotic) lesions. Conclusions: The patient complaints were significantly associated with clinical manifestations, so that pain and burning sensation were more common in patients with erosive lesions. Knowledge of the main complaints and clinical manifestations helps dentists diagnose the disease at an early stage and refer patients to specialists in a timely manner.

    Aim: The present study evaluated color changes caused by endodontic repair materials in a simulated regenerative endodontic procedure (REP). Methods: Fifty-six bovine incisors were randomly distributed into three experimental groups according to the repair cement placed over the blood clot [Conventional white MTA (Angelus), MTA Repair HP (Angelus), and Bio-C Repair (Angelus)] and a control group (n=14). Color measurements were taken before the access cavity preparation, one week, one month, three months, and six months after REP. The CIELAB system was chosen to calculate color change (ΔE), and the generalized estimating equations model was used to compare mean ΔE values between cements and periods. Results: Teeth from the three cement groups exhibited a clinically perceptible color change. No significant differences between groups were found in any experimental period. Within each group, MTA Repair HP and Bio-C Repair exhibited significantly greater color change at the six-month evaluation. Conclusions: The three endodontic repair materials caused similar changes in tooth color when used as a cervical plug in a simulated REP.

    Objectives: Facial paralysis is recognized as the most prevalent complication following parotidectomy. This study aimed to evaluate the symptoms and post-operative complications of parotidectomy while employing facial nerve preservation techniques. Methods: The study involved 14 patients (9 men and 5 women) with a mean age of 53.0 ± 16.5 years. Clinical characteristics, facial paralysis, and other complications in these patients were monitored at three post-operative intervals: 1 week, 1 month, and 3 months. Results: Following ultrasonography, homogeneous echo textures were observed in 64.3% of tumors compared with 35.7% with heterogeneous textures. Regarding tumor locations, 50% were found in the superficial lobe, 14.3% in the deep lobe, and 35.7% involving both lobes. The FNA (Fine Needle Aspiration) test identified 64.3% of the tumors as pleomorphic, 13.3% as oncocytomas, 7.1% as Warthin tumors, and 14.3% as other benign tumors, with no cases suspected of cancer. Post-operative complications: Temporary facial paralysis was noted in 57.1% of cases at one week post-operation, declining to 28.6% after one month and 14.3% after three months. Hemorrhage occurred in 7.1% of patients, with no reports of infection, skin flap necrosis, or postoperative seroma. Additionally, 92.9% of patients experienced ear numbness at one week post-operation, decreasing to 21.4% by three months. Conclusion: the study demonstrates that parotidectomy, when performed with careful preservation of the facial nerve, is an effective and constructive approach for removing pleomorphic tumors in the parotid gland
