The aim of this integrative review consisted of verifying whether the oral manifestations detected in patients diagnosed with COVID-19 are useful in diagnosing the disease, whether they are a manifestation resulting from the disease, or whether there is evidence that there is no correlation between the pathologies. Therefore, articles in the PubMed, Lilacs, Scopus, Science Direct, Web of Science and Embase databases were searched, in addition to the search in gray literature. The terms used in the search were: “COVID-19” or “Sars-Cov-2” or “coronavirus” and “oral conditions” or “oral health” or “oral manifestations” and “diagnosis/complications” or “symptoms”. Thus, 1.305 articles were selected, of which 61 were selected to compose this review. Most of the included studies considered oral symptoms as taste changes, xerostomia and ulcerative lesions in the oral and labial mucosa. All symptoms related to this pathology still need further studies and investigations so that all mechanisms and manifestations related to it are completely elucidated.

The aim of this work is to review the literature on the use of herbal medicines to control dental anxiety. For this purpose, articles were searched in the databases ScienceDirect, Pubmed and The Cochrane Library. 57 articles were included in this study. The research evidence points to Valeriana officinalis and Passiflora incarnata as the most studied herbal medicines for the control of anxiety, and their adverse effects are also investigated. Studies prove the relative safety of these medications, as well as their effectiveness, low cost, lower concentration of active ingredients with better effects and fewer side effects when compared to benzodiazepines. The use of these medicinal plants requires further clarification as to their real effectiveness, correct dosage and side effects in conscious sedation in Dentistry.

Anxiety in dental patients is a problem for both dental surgeons and patients. Thus, therapies that aim to control this anxiety and thus favor the patient's collaboration during treatment become factors frequently studied in search of the best alternative for this purpose. Therefore, the objective of this work is to review in the literature the use of herbal medicines in the control of dental anxiety. The bibliographic search was carried out in the databases ScienceDirect, Web of Science, Scielo, Pubmed, The Cochrane Library. 57 articles were included in this study. Research evidence points to Valeriana officinalis and Passiflora incarnata as the most studied herbal medicines for controlling anxiety and adverse effects. Studies prove the relative safety in the use of these drugs, as well as their effectiveness, low cost, less concentration of active ingredients with better effects and lesser side effects when compared to benzodiazepines. However, the use of these medicinal plants requires further clarification as to their real effectiveness, correct dosage and side effects in conscious sedation in Dentistry.

Endodontic retreatment continues to be a challenge for Endodontics, as well as supporting techniques that aim to improve and assist in the elimination of microorganisms that have infected root canal systems and led to the development of peripicopathies, such as Passive Ultrasonic Irrigation (PUI) and Photodynamic Antimicrobial Therapy (aPDT) have been frequently used. Thus, the aim of this paper is to report a clinical case of endodontic retreatment of tooth 47 with a diagnosis of endoperiodontal injury associated with periapical lesion. The treatment was carried out in two sessions, using as intracanal medication calcium hydroxide with parachlorophenol with camphor, PUI in both final irrigations and previously the root filling was performed with aPDT. At the end of the treatment it was possible to observe a reduction in the radiolucent areas, suggesting the beginning of bone repair. This case report suggests that PUI and aPDT associated with endodontic retreatment can improve disinfection, favoring the regression of periapical alterations and, consequently, favoring the bone repair process.
