OBJECTIVE: Questionnaires designed to test knowledge and self-perception can be valuable tools for diagnosing a dentist\'s understanding of the management and administration of a practice. The objective of this study was to create and authenticate a questionnaire for assessing dentists\' self-perception on oral healthcare management developed from discussions with experts in this field.
METHODS: In order to create and verify a questionnaire survey, a cross-sectional, descriptive, and analytical study was carried out. Participants\' personal information and 31 statements across four categories made up the final questionnaire form. The answers to the questionnaire were in the form of a Likert scale. After refining the initial version, a total of 36 interviews were conducted at dental offices to verify the validity. For the Exploratory Factor Analysis (EFA), we used the Kaiser-Meyer-Olkin (KMO) index, the Bartlett sphericity test, and also Cronbach alpha coefficient for the validity of the questionnaire.
RESULTS: The accuracy of the instrument was measured by intrarater and interrater reliability. For the EFA, all the communalities exceeded the threshold of 0.05. With a Cronbach\'s alpha coefficient of 0.898, the questionnaire has sufficient internal consistency.
CONCLUSIONS: The questionnaire demonstrates robust reliability and validity, thereby affirming its suitability for its intended purpose.

Dentistry is changing rapidly in a dynamic and challenging mode and is incorporating digital technology, communication, and managerial skills for profitable enterprises. On the new dental horizon, the profession requires engaging and inspiring role models and leaders. Ιdentifying and developing human soft skills can improve quality issues and guarantee a sustainable dental business. The concept of leadership is a very complex and multidimensional phenomenon as observed from the current literature. In different commercial environments, there has been a huge discussion on the specific characteristics of an effective leader. In dentistry, the subject needs further investigation. This article aims to bring up the importance of dental leadership and highlights the need of identifying dental leaders committed to excellency. It also challenges the need for educational shift on dental leadership management. Finally, it aims to support and develop educational transformations based on positive preliminary data observed by incorporating a new, relevant subject in the dental curriculum.

OBJECTIVE: We aimed to assess the association between molar incisor hypomineralization (MIH) and the oral health-related quality of life (OHRQoL) in a group of 7- to 14-year-old children in Berlin, Germany.
METHODS: The cross-sectional study consisted of a consecutive sample of 317 children, aged 7-14 years (49% girls, 51% boys; mean age, 8.71). Data were collected between June 2018 and December 2019. MIH was diagnosed using the criteria of the European Academy of Paediatric Dentistry. OHRQoL was assessed using the German 19-item version of the Child Oral Health Impact Profile (COHIP-G19). Differences in COHIP-19 summary scores between controls without MIH and MIH patients and with regards to MIH severity were tested for statistical significance using t test and analysis of variance (ANOVA), respectively.
RESULTS: Data were obtained for 217 untreated MIH patients and 100 controls. OHRQoL of MIH patients was significantly more impaired than of controls indicated by COHIP-19 mean scores (60.9 ± 10.7 vs. 67.9 ± 7.8; p < 0.001). Patients with severe MIH (59.6 ± 11.0) reported significantly worse OHRQoL than patients with mild MIH (63.6 ± 9.1; p = 0.013).
CONCLUSIONS: MIH has a significant negative impact on the children\'s OHRQoL. Patients with severe MIH experience a greater negative impact on OHRQoL than those diagnosed with mild MIH.
CONCLUSIONS: MIH is one of the major dental problems of our time; pediatric dentists should be aware of its impact on the OHRQoL of the patient.

BACKGROUND: The dental treatment of individuals with intellectual disability can represent a considerable professional challenge.
OBJECTIVE: To develop a model for predicting the behavior of patients with intellectual disability in the dental office.
METHODS: The study group comprised 250 patients with Down syndrome (DS), autism spectrum disorder (ASD), cerebral palsy (CP), idiopathic cognitive impairment or rare disorders. We collected their demographic, medical, social and behavioral information and identified potential predictors (chi-squared test). We developed stratified models (Akaike information criterion) to anticipate the patients\'behavior during intraoral examinations and to discern whether the dental treatment should be performed under general anesthesia. These models were validated in a new study group consisting of 80 patients. Goodness of fit was quantified with sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and area under the receiver operating characteristic curve (AUC). We developed a mathematical algorithm for executing the models and developed software for its practical implementation (PREdictors of BEhavior in Dentistry, \"PREBED\").
RESULTS: For patients with DS, ASD and CP, the model predicting the need for physical restraint during examination achieved a PPV of 0.90, 0.85 and 1.00, respectively, and an NPV of 0.66, 0.76 and 1.00, respectively. The model predicting the need for performing treatment under general anesthesia achieved a PPV of 0.63, 1.00 and 1.00, respectively, and an NPV of 1.00, 1.00 and 0.73, respectively. However, when validating the stratified models, the percentage of poorly classified individuals (false negatives + false positives) ranged from 24% to 46.6%.
CONCLUSIONS: The results of the PREBED tool open the door to establishing new models implementing other potentially predictive variables.

BACKGROUND: Osteonecrosis of the jaw is a very delicate side effect of Denosumab. The aim of this retrospective study was to assess the occurrence rate of Denosumab-related osteonecrosis of the jaw (DRONJ) at the Cancer Institute of Lorraine (ICL) and to highlight necrosis risk factors.
METHODS: To that purpose, we analyzed the medical records of 249 consecutive patients treated with Denosumab at the ICL during the past 5 years. Patients who received orofacial radiotherapy or a previous treatment with a bisphosphonate were excluded. The P-value was set at .005.
RESULTS: A total of 141 patients treated at the ICL between January 2010 and December 2015 were included. All patients were treated with XGEVA® . Of the 141 patients included in the study, 10 developed DRONJ. The incidence of DRONJ increases with the duration of follow-up as follows: 3% at 1 year, 7% at 2 years, and 8% from 30 months on. No risk factor for necrosis could be identified except the realization of prior dental extraction (P = .025).
CONCLUSIONS: Our results raise important questions about the dental management of these patients, in particular, concerning the healing period between dental extractions and the initiation of Denosumab.
