Nowadays low bone density has affected a large number of children. Bone fractures are a major cause of hospitalization for children before age of 17 [1] and an increase in child fracturing bone rates has been reported over the past 2 decades [2]. Childhood factors such as lifestyle, diet, chronic illness, and medications have a short-term effect on bone health and a long-term effect on maximizing bone mass which affecting adult mortality [3].

Introduction: The aim of the present study was to evaluate the diagnostic accuracy of a rapid test to determine SARS-CoV-2 infection in a population of workers who provided services during the COVID-19 pandemic at a University Dental Hospital.
Materials and Methods: Diagnostic accuracy was studied by comparing a commercial rapid test (PambioTM COVID 19 IgG/IgM rapid test device. ABBOTT®) to a blood test for enzyme-linked immunosorbent assays (ELISA test) as the gold standard in 284 workers at the Dental Hospital at the Buenos Aires University Dental School during the COVID-19 pandemic.
Results: Rapid test sensitivity was 0.44 (CI95: 0.14 to 0.79) and specificity was more than double (0.89; CI95: 0.85 to 0.93). The Positive predictive value was 0.12 (CI95: 0.03 to 0.27), but the negative predictive value was much higher (0.98; CI95: 0.95 to 0.99). The positive and negative likelihood ratios were 4.07 (CI95: 1.82 to 9.11) and 0.62 (CI95: 0.35 to 1.12), respectively.
Conclusion: Although it could be used for monitoring previous exposure to COVID-19 in dental health care workers, it should only be used in environments with inadequate access to more complex diagnostic tools. This method should not be used as the sole basis for treatment or other management decisions.

Integrated treatments (periodontal-occlusal-restorer) can be performed in a totally digital way and patient’s request is dictated by these resources. This case report involves a young female who presented esthetic dissatisfaction and fracture in composite resin restorations. Clinical examination revealed inadequate canine guidance in lateral excursion, and the upper right canine presenting a gingival difference in relation to left. The treatment plan included the digital planning with intraoral, extraoral photographs and intraoral scans allows for aesthetic planning, as well as previews through the software, being especially helpful when the treatment involves periodontics. Digital waxing and evaluation with the virtual articulator in the current software collaborates fundamentally for the evaluation of the anterior and lateral disocclusion guides, favoring the longevity of the restorative treatment. Additionally, the mock-up and provisional prosthesis can be machined, presenting an evolution in relation to the adaptation and a decrease in time when compared to the traditional method. Once the provisional prosthesis has been approved, the milling machine is capable of machining exactly the same size and shape as previously demonstrated to the patient, thus avoiding problems of aesthetic or occlusal differences inherent in the traditional process. Esthetic results and patient satisfaction were monitored for 18 months and were very satisfactory. Clinical significance: at all stages, the digital protocol for integrated treatments is predictable and efficient, allowing easy diagnosis, improved communication with the patient, clinical and prosthetic work safety and treatment longevity. Keywords:Digital Smile Design; Esthetic Dentistry; Esthetic Parameters; Digital Planning
