Conservative management of dentigerous cyst in children: Report of two clinical cases.

The dentigerous cyst is the second most common odontogenic. The prevalence rates ranging from 0.8% to 3.6% in the general population. It affects people especially at the second and third decade of life with a male predilection. It presents a preference for the mandibular region particularly for the second lower premolar. Surgical marsupialization or decompression are the most conservative treatment modalities as it prevents the risks of cyst removal as nerve injuries and preserves the unerupted tooth. Two clinical cases of two young patients presenting a dentigerous cyst involving impacted teeth, which were successfully treated by decompression will be reported in order to highlight the benefits and limits of cyst decompression as well as detailing its operating protocol and its instructions.

Medical students' resilience level and its associated factors: A Tunisian study.

INTRODUCTION: Resilience is one's ability to adapt to internal and external stressors and cope with challenges encountered throughout life. AIM: Our work aimed to determine resilience levels at the Medical University of Ibn El Jazzar-Sousse (Faculty of Medicine of Sousse) Tunisia and to identify the key factors influencing resilience in order to help students improve their college experience, as well as their future career and eventually their quality of life. METHODS: It's a cross-sectional study conducted during October and November 2021 at the FMS including all undergraduate medical students using a questionnaire elaborated in French language and composed of 02 major parts Socio-demographic and general health data and The Connor-Davidson Resilience Scale (CD-RISC). Data were collected using Google Forms platform via social networks (Facebook students' groups). RESULTS: A total of 225 participants filled the questionnaire; the mean age was 21±5 years. Among them 75.1% were females (sex ratio=0.33). The total resilience mean score was 56.36±12.43. Comparison of resilience scores according to different covariates showed that resilience was positively associated with male gender, extracurricular activities, relationships with both colleagues and teachers and physical exercise, but negatively associated with imposed course of study and perception of both study difficulties and personal academic results. No correlation was found between resilience score and age. CONCLUSIONS: This work encourages university administrators to devote more resources to promote resilience, and it emphasizes the importance of implementing new educational and entertaining interventions to improve students' ability to deal with academic challenges.

Cone-beam computed tomography in the diagnosis of regional odontodysplasia.

Regional odontodysplasia (RO) in permanent teeth is a rare developmental anomaly of mineralized tissues. Three-dimensional images and data from CBCT allowed to provide useful information on the degree of tooth calcification and consequently confirm the diagnosis of RO and establish a treatment strategy to minimize future damages and sequels.

Severe Acute Respiratory Syndrome Coronavirus 2 and Dentistry: A Summative Review of Guidelines issued by National Health Authorities.

COVID-19 was first reported in China, in November 2019 and since then the spread of this disease was so rapid that on March 11, 2020, it was declared a pandemic by the World Health Organization. Due to the high transmissibility of the COVID virus and the associated morbidity and mortality, various International and National health authorities released different guidelines for day-to-day living, laying down "new norms" which has impacted our lives enormously. Although these guidelines seem to be convoluted but owing to some differences in the guidelines, it raises an ambiguity in the minds of dentists. Hence, we felt the need of this review to summarize different guidelines issued by various National health authorities for catering emergency and routine dental care. We included guidelines from CDC, ADA, NHS, India, UAE, Egypt, and Tunisia and compared and consolidated to reach a consensus that teledentistry is a good alternative to face-to-face management for nonemergency patients. Triage should be done for all patients coming to the health-care facility. Temperature and other vital parameters should be recorded in our daily practice. Antibacterial mouth rinses before the dental procedure can reduce the microbial load and therefore can alleviate transmission. To reduce indirect transmission through fomites on inanimate objects various waiting area changes must be ensured. Air conditioners can be used in well-serviced conditions with due care given to ventilation of the operatory after each patient. Strict disinfection protocols and personal protective equipment for dentist safety are mandatory.

Multiple abnormalities in permanent incisors diagnosed six years after a severe intrusive injury in the primary dentition: A case report.

Severe intrusion injuries of primary teeth are frequently associated with serious developmental disorders. This report describes the diagnostic procedures and the multidisciplinary approach for multiple sequelae to permanent incisors due to a severe intrusive injury of the primary maxillary anterior teeth at the age of 18 months in a 7-year-old girl. Clinical examination revealed hypoplasia of tooth 22, and radiographic examination showed crown-root malformation of tooth 21, impaction of tooth 11, and the presence of an odontoma-like malformation on tooth 12. The affected tooth 12 had a poor prognosis, as highlighted by CBCT, and it was extracted. While for the impacted 11, a surgical extraction followed by an orthodontic treatment is scheduled. Aesthetic and functional problems were solved by a functional space maintainer using a removable partial denture. The occurrence of multiple abnormalities in permanent teeth as a result of intrusive injuries in the primary dentition enhances the need for creating awareness among dentists not only of the importance of appropriate immediate management of trauma but also of the importance of establishing a long-term follow up and subsequent management of any sequelae.
