No full textOral health and severe systemic diseases: a retrospective study on clinical and radiographic parameters
No full textThis study aims to investigate the correlation between oro-periodontal health and the presence of severe systemic diseases, classified according to the American Society of Anesthesiologists (ASA) as ASA III-IV, compared to healthy patients or those with mild to moderate systemic conditions (ASA I-II). The main objective is to assess whether specific clinical and radiographic parameters, as observed through panoramic radiographs, can serve as predictive indicators of systemic risk, potentially offering screening tools within dental practice to support interdisciplinary diagnosis. MATERIALS AND METHODS A retrospective study was conducted on a sample of 501 digital panoramic radiographs (OPTs) of adult patients examined at the Azienda Ospedale Università di Padova. The cohort included individuals across various ASA classifications, with a balanced distribution in terms of age and gender. Seven oro-periodontal parameters were assessed: number of missing teeth, average bone loss, DMFT index (Decayed, Missing and Filled Teeth), presence of periapical lesions, bony or soft tissue neoformations, residual roots, and radiographic signs consistent with pericoronitis. The association between these parameters and systemic health status was analyzed using multivariate logistic regression models, adjusting for potential confounding factors such as age and lifestyle habits. RESULTS AND CONCLUSIONS Statistical analysis revealed a significant association between average bone loss and the presence of severe systemic diseases (p < 0.001), as well as between periapical lesions and systemic comorbidities (p < 0.001). Residual roots and pericoronitis also showed statistically significant associations (p < 0.05). Interestingly, the number of missing teeth was higher in the ASA I-II group (p = 0.035), possibly reflecting the influence of social or behavioral factors. The DMFT index and neoformations did not show significant associations. These findings suggest that average bone loss and periapical lesions may serve as key radiographic markers for identifying patients at increased systemic risk. CLINICAL SIGNIFICANCE Systematic monitoring of oro-periodontal parameters through routine radiographic evaluations may represent a valuable tool in the secondary prevention of systemic diseases. Early diagnosis and prompt treatment of oral infections-particularly in patients with complex clinical profiles-could help reduce the risk of systemic complications and improve overall patient quality of life. A multidisciplinary approach is therefore crucial in managing patients with comorbidities, promoting a comprehensive view of health
Hypnosis as sole anesthesia for oral surgery: The egg of Columbus
No full textBackground and Overview: Hypnosis, despite its effectiveness, has been neglected. The aim of this study is to show the effectiveness and manageability of hypnosis as a stand-alone technique in dentistry. Case Description: Three patients underwent 6 oral surgery procedures (surgical third-molar removal, implant surgery, maxillary bone augmentation, and mucogingival surgery) with hypnosis as the only anesthetic. Two of the 3 patients had difficulties: 1 was sensitive to multiple chemicals, had Addison disease, and had previously experienced anaphylactic reactions to local anesthetics; the other was allergic to lidocaine and had undergone a paradoxical reaction to pharmacologic sedation in the past. All 3 patients had 2 preoperative sessions each to assess their perioperative risk, level of anxiety, hypnotic susceptibility, and capacity to develop full hypnotic analgesia. On a surgery day, hypnosis was induced and hypnotic analgesia was obtained according to a standard protocol, a procedure taking no more than 9 minutes in each case. Each surgical procedure was then completed successfully with the patient in a painless condition of full relaxation and sense of well-being, with stable cardiovascular parameters. None of the patients required postoperative analgesics, which were prescribed for use as needed. Conclusions and Practical Implications: Hypnosis is a valuable tool in dentistry, enabling the safe and rapid relief of anxiety and phobia and raising patient pain thresholds to the level of surgical analgesia. Unlike drugs and equipment, it is always readily available, cost-free, and has no adverse effects when administered by competent professionals. Hypnosis can be used for sedation in most patients and as a stand-alone technique in those with appropriate hypnotic susceptibility, improving the well-being and safety of patients
Calculated Energy Response of Some RTL Detectors with Multi-Element Filters
No full textOne of the inconvenient features of thermoluminescence detectors is the energy dependence of their response. A calculational method is presented which enables filters to be selected for most thermoluminescent detectors to achieve any described response over the energy range 30 keV to 1.5 MeV
Conservative treatment of Medication-Related Osteonecrosis of the Jaw (MRONJ) with topical ozone
No full textOBJECTIVES The aim of this case report is to describe the conservative treat ment of medication-related osteo necrosis of the jaw (MRONJ) using topical ozonated gel. Medication-related osteonecrosis of the jaw is defined as a “drug-re lated adverse reaction character ized by the progressive destruc tion and necrosis of the mandibu lar and/or maxillary bone in pa tients exposed to medications known to increase the risk of the condition, in the absence of previ ous radiation therapy”. Epidemiological data on this con dition are supported by robust studies, highlighting significant variability between patients re ceiving high-dose and low-dose treatments, with a higher inci dence in the former group, and across different drugs (class, ac tive ingredient, route of adminis tration, and dosage). Clinically, the most frequently ob served sign is the persistence of bone exposure for more than 8 weeks. However, there are other Ospedale-Università di Padova, from another region initially for suspicion of osteomyelitis in the right hemimandible. diagnostic criteria, referred to as ‘minor’ signs and symptoms. It is important to note that not all cas es of MRONJ present with bone exposure; therefore, in cases of suspicion, these criteria should be further investigated using radio graphic imaging. Radiological investigations are fundamental in the diagnostic work-up, particularly orthopanto mography (OPT) and intraoral ra diographs (first-line), along with computed tomography (CT) (sec ond-line), although radiological signs tend to be non-specific. Diagnosis of MRONJ is primarily based on clinical and radiological findings. MATERIALS AND METHODS A literature review was conducted by consulting the Pubmed data base. The clinical case of a patient referred to the all’Ambulatorio di Patologia e Medicina Orale e Diagnostica Odontostomatologica dell’Unità Operativa Complessa di Clinica Odontoiatrica dell’Azienda Based on the patient’s clinical his tory and the observed clinical and radiological signs and symptoms, a diagnosis of MRONJ was made, as the patient had been taking alendronate for 5 years. The case was classified (stage 2b according to the SIPMO-SICMF classification, with peri-implantitis affecting an implant in the left mandibular region) and treated with topical applications of ozo nated gel. RESULTS In the clinical case reported thanks to the use of topical ozone, a complete healing of the mucosa and partial bone re-mineralization of the site of MRONJ at stage 2b (according to SIPMO/SIMCF 2023 classification) and a total re gression of perimplantitis were achieved, with the possibility of maintaining the implant in arch was observed. ratterizzata dalla progressiva distruzione e necrosi dell’osso mandibolare e/o ma scellare di soggetti esposti al trattamento con farmaci per cui sia accertato un au MRONJ is associated with the use of certain drug classes, and it is crucial to be aware of drug-relat ed, systemic, and local risk fac tors. Early diagnosis enables a more conservative approach to treatment, minimizing the biologi cal burden on patients. CONCLUSIONS While stabilization is commonly regarded as the primary outcome for MRONJ treatment, in this case, complete healing was achieved with a non-invasive approach. CLINICAL SIGNIFICANCE This report describes a case of effective conservative treatment for MRONJ and peri-implantitis using an easy-to-use medical device

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
