Kabuki Syndrome and oral health
No full textKabuki Syndrome (KS), also known as Niikawa-Kuroki Syndrome, is a rare congenital disorder first discovered in Japan in 1981. This disorder owes its name to the resemblance of patients’ facial features to the makeup of traditional theatre actors. The prevalence of KS in Japan is estimated at 1:32,000 live births. The live birth prevalence outside Japan presumably approximates that seen in the Japanese population. It has been calculated a minimum birth incidence of 1:86,000 in Australia and New Zealand. The presence of individuals with KS within the same family has suggested an autosomal dominant transmission. Although several chromosomal abnormalities have been associated with this syndrome, mutations in the KMT2D, MLL2 and KDM6A genes are considered to date, the main causes of Kabuki Syndrome. The current literature is poor in information regarding oral health findings in patients affected by KS. The aim of the present systematic review was to review the literature about oral health features associated with KS

No full textThe assessment of the value of learning communication skills in dental hygiene students
No full textBACKGROUND: Communication skills are fundamental for medical and dental professionals. To the best of our knowledge, no study has explored dental hygiene students’ attitudes within a communication skills learning and teaching context. The aim of the present study was to assess how dental hygiene students value the learning of communication skills.
METHODS: A comprehensive survey about was developed and electronically distributed to the dental hygiene students of the first, second, and third year from the dental hygiene bachelor’s degree. The dental hygiene students were administered a questionnaire that included a first section (developed to collect students’ demographic data, such as age, gender, year of bachelor’s degree), the Student Attitudes Toward Communication Skills Survey, and the Communication Skills Attitude Scale.
RESULTS: Dental hygiene students thought that the “Value to Profession” component of learning communication skills was as valuable as the “Value to Self” component. A statistically significant difference between modes of communication was observed: the f-ratio value was 10.46007 (P<0.0005). The students thought that learning verbal communication skills was more important and valuable than learning written or nonverbal skills. Half of the students with high total value found learning communication skills to have high intrinsic value, attainment value, utility value and was a good use of their time.
CONCLUSIONS: Dental hygiene students, as well as other healthcare programs students, may find time management to be a concern and source of stress, thus being a limitation for the improvement of communication skills
Variation of mandibular radiomorphometric indices in metastatic bone cancer patients undergoing antiresorptive treatment: a prospective study
No full textIntroduction The aim of this study was to identify and evaluate the changes of oral health and panoramic radiograph indexes in cancer patients that have been administered antiresorptive drugs. Materials and methods Subjects who had a diagnosis of cancer with bone metastasis that were about to start antiresorptive therapy with denosumab or zoledronic acid were included. A preliminary dental clinical assessment, together with a panoramic radiograph, was performed at T0 to prevent the onset of Medication related osteonecrosis of the jaw (MRONJ) and T1 (1 year follow up). In order to calculate at both T0 and T1 the mandibular cortical width (MCW), the panoramic mandibular index (PMI), and the mandibular cortical index (MCI), panoramic radiographs were analyzed by a single operator. Results Thirty-three subjects with a mean age of 59.9 years were included in the study. A significant reduction in the PMI value from T0 to T1 (p = 0.00236) and a significant variation from T0 to T1 for MCI (p < 0.05) were observed. Conclusions Radiomorphometric indices could represent a promising field of research that can take advantage from the easy detectability in dental panoramic radiographs. Further research is needed to explore the possible role of PMI and MCI in bone cancer patients
A systematic review on oral, head and neck, and systemic features associated with Niemann Pick disease
No full textINTRODUCTION: Niemann-Pick disease (NPD) is a group of rare, autosomal recessive disorders characterized by the abnormal accumulation of sphingolipids and cholesterol in various cells throughout the body. This heterogeneous group of diseases is classified into different subtypes, primarily A, B, C, and less common D, E, and F, each with distinct underlying enzymatic or genetic etiologies and clinical presentations. The classification is crucial as it dictates the severity, progression, and specific manifestations of the disease. The aim of this review was to synthesize the current understanding of NPD, with a particular focus on its oral and dental implications. By examining these articles, we seek to highlight the importance of recognizing and addressing the oral health needs of individuals with NPD.
EVIDENCE ACQUISITION: This review followed PRISMA-ScR guidelines and investigated the link between NPD and oral or craniofacial manifestations. A literature search was conducted in four databases (PubMed, Scopus, Embase, Web of Science) using relevant keywords. Only English-language articles were included, and study selection was based on predefined PICO criteria.
EVIDENCE SYNTHESIS: A total of 5 articles were included in the review. The initial search identified 23 records; after removing 3 duplicates and excluding 4 based on abstract screening, 16 full-text articles were assessed for eligibility. Of these, 5 met the inclusion criteria.
CONCLUSIONS: In conclusion, this review highlighted the systemic complexity of NPD and its impact on oral health. It also underscored the need for multidisciplinary care and personalized dental management. Further studies are needed to clarify the causes of oral manifestations and to establish evidence-based dental guidelines for NPD patients
Oral and craniofacial features associated with neurofibromatosis type 1
No full textNeurofibromatosis type 1 (NF1) is a common autosomal dominant genetic disorder characterized by a wide spectrum of clinical manifestations affecting the skin, nervous system, bones, and oral cavity. This comprehensive review focuses on the oral and maxillofacial features of NF1, which are present in over 70% of patients and can significantly impact dental and skeletal health. Key oral findings include neurofibromas affecting both soft and hard tissues, dental anomalies, jaw deformities, malocclusion, and alterations in the temporomandibular joint. Radiographic anomalies such as enlarged mandibular canals and foramina are frequent. Although the relationship between NF1 and dental caries remains debated, patient education and preventive care are crucial. Early diagnosis through clinical signs such as café-au-lait spots, axillary freckling, and intraoral lesions is essential for appropriate management and genetic counseling
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
