Treatment of injection-induced ecchymoses with light/laser-assisted technology

An increasing number of minimally invasive cosmetic procedures, such as filler or botulinum toxin injections, are performed annually. These procedures are associated with a high risk of post-procedure bruising or ecchymosis. Ecchymoses arise following hemorrhage and extravasation of red blood cells into the subcutaneous tissue, leading to local skin discoloration. Although ecchymoses generally resolve within 14 days, their appearance is cosmetically bothersome, and they may be painful and cause major distress to patients. Recent clinical evidence suggests that light/laser technology with pulsed dye laser (PDL) or intense pulsed light (IPL) can dramatically alleviate and minimize bruising when delivered within 24-72 hr of the injection. This article, will review reports of treatment of ecchymosis by lasers and IPL

How to deal with coronavirus disease 2019: A comprehensive narrative review about oral involvement of the disease

OBJECTIVES: The aim of this narrative review was to collect all findings from literature about oral signs and symptoms of COVID-19, in order to draw a picture of oral involvement of this challenging viral infection, to help oral professionals in a better triage and early diagnosis.MATERIAL AND METHODS: The search for international literature was made including articles written in English and reporting about oral manifestations in patients with a diagnosis of COVID-19. The publication time was limited to 2019 and 2020, up to May 20, 2020. A narrative review was performed.RESULTS: Twenty-three articles were included in this review. Three different oral manifestations were found: taste alteration, oral blister and ulcers, and oral lesions associated with Kawasaki-like diseases (erythema, bleeding of lips, "strawberry tongue"). The higher expression of Angiotensin-converting enzyme 2 in the oral cavity and in endothelial cells might be responsible for oral manifestation and the major report of signs and symptoms in the occidental countries.CONCLUSIONS: Detecting oral signs and symptoms of COVID-19 could be useful to perform a better preliminary triage in dental setting, and in recognizing possible early manifestations of the disease. However, considering the outbreak of COVID-19 and the consequent difficulty of undergoing oral examinations, the oral manifestations might be misdiagnosed; then, we would encourage oral professionals to perform other studies about this topic

Aesthetic Dentistry, How You Say and How You See: A 500-People Survey on Digital Preview and Color Perception

Purpose: Digital technologies have improved ways to perform aesthetic dentistry in the last few years. The aims of this survey were to investigate the most preferred way to preview the result of an aesthetic dental rehabilitation among a population of dental professionals and laypeople and to compare aesthetic standards of the general population and dentists in terms of the color of teeth for aesthetic dental rehabilitations. Patients and Methods: A questionnaire was sent to the subjects (dentists and laypeople) during a 1-year period and, together with their demographic data, different ways to preview the result of an aesthetic rehabilitation were submitted, such as digital smile design, dental wax-up and oral explanation. Furthermore, an additional section of the questionnaire inves-tigated the most suitable color for an aesthetic rehabilitation based on the colors of the VITA Scale. Results were statistically analyzed (with Chi-square of independence and Mann\u2013 Whitney U-test) highlighting differences of answers based on age groups, educational attainment, gender, and belonging or not to the dental field. Results: Findings showed that digital smile design (digital preview) is a high-appreciated method for previewing and communicating with patients both by dental professionals and laypeople. Furthermore, lighter colors were found to be more valued by laypeople and significant differences were highlighted between the two populations assessed. Conclusion: It seems to be viable to use digital preview for dentists and laypeople to improve previewing and communicating ways. It might be advisable to better motivate patients in recognizing aesthetical features and to raise their awareness in preferring more mimetic aesthetic results. Great opportunities are opened up by digital smile design in teaching, learning, and routine practic

Proposal for Introducing a Digital Aesthetic Dentistry Course in Undergraduate Program: Contents and Ways of Administration

Background: Nowadays, digital dentistry is a fundamental skill that dentists need to acquire at this time. The digital workflow has gained acceptance and is widely used in most disciplines of dentistry. For this reason, it might be advisable to include this content in the undergraduate curriculum. The aim of this work was to create a course in digital aesthetic dentistry and evaluate its effectiveness. Methods: Dental students at the University of Verona (from third to sixth year) participated in a 2-h course on photography, digital aesthetic analysis, and digitally planned rehabilitations. Students were randomly divided into two groups, the first group attending the course with video tutorials and the second group attending the traditional class with slides. The students’ ability to perform digital aesthetic analysis and rehabilitation was tested. In addition, a questionnaire was completed to determine student satisfaction with the course and method of delivery. Statistical analysis was performed. Results: The course was highly appreciated, especially by the students who received the video tutorials. Good results were obtained in the performance of digital analysis and rehabilitation, which were better in the first group. Conclusions: Digital aesthetic dentistry was a success in terms of newly acquired skills. From this point of view, the proposal of a course on this subject in the undergraduate curriculum deserves a close evaluation. The video tutorial method seems to be a good way to teach operative digital procedure

Surgical and histological evidence of case reports showing Schwannomas in the nasal area

Introduction and importance: Schwannomas are benign neurogenic neoplasms with an uncommon involvement of the nasal cavity and paranasal sinus, which usually appear as a painless formation. We report two cases of nasal schwannoma that was successfully treated by surgical excision with satisfactory functional outcomes. The aim of this study is to discuss the clinical assessment and imaging, (CT, MRI) differential diagnosis, histological examination, surgical approaches of this rarely encountered neoplasm in the sinus-nasal area. Case presentation: Case 1: a 53 years-old Caucasian male, hospitalized in the ENT Department with a 5-month progressive history of right nasal obstruction without epistaxis was diagnosed as a Schwannoma following clinical, histology and ENT endoscopy examination. Case 2: a 45 years-old Caucasian male with asymptomatic swelling arising 4 months before in the nasal tip area with progressive nasal deformity, diagnosed as a schwannoma and analyzed with MRI. Clinical discussion: Case 1: The patient had an uneventful post-operative course and a follow-up examination at 36 months showed no recurrence of the neoplasm with satisfactory functional result. Case 2: The patient had an uneventful post-operative course and a follow-up examination at 5 years showed no recurrence of the neoplasm and satisfactory aesthetic result. Conclusions: Schwannomas arising from sinonasal area are extremely rare, painless and with slow-growing evolution. The surgical option and histologic analysis are mandatory for a correct diagnosis
