Background The evidence on the relationship between anxiety and depression and patients with distinct subtypes of temporomandibular disorder (TMD) is uncertain, so a thorough review study on the topic is still missing. Objectives This systematic review investigated the distribution and severity of anxiety and depression in patients diagnosed with different subtypes of TMD. Methods The study is registered in PROSPERO (CRD42020150562) and it followed the PRISMA 2020 Statement. We searched in PubMed, Web of Science, Scopus and SciELO databases (last search: 12 March 2021) and the reference list from the included studies. Study eligibility criteria consisted of: (i) patients diagnosed with TMD using the Research Diagnostic Criteria (RDC/TMD) or Diagnostic Criteria (DC/TMD) instruments; (ii) assessment of anxiety and/or depression with validated psychological instruments and (iii) allocation of patients into a minimum of two distinct TMD subtypes with at least one group having myofascial pain (comparison group). Analyses were carried out using RevMan 5.3.5 statistical package and random‐ or fixed‐effects models (α = 0.05). The quality of evidence was assessed based on review authors' judgment derived from a 10‐item appraisal tool for prevalence studies and with the Newcastle–Ottawa scale. Results Of the 4086 records identified in total, 24 were eligible for inclusion; meta‐analyses were conducted with 20 studies. In total, 3678 subjects were included in the review. Most of the studies found that patients with myofascial pain showed similar occurrence and severity of anxiety/depression as compared to other subtypes of TMD, although the average prevalence seemed to be higher among the diagnoses consisting of myofascial pain (muscular TMD). Despite the moderate‐to‐high heterogeneity, anxiety and depression were more frequently distributed within patients with myofascial pain (p = .001). TMD patients without myofascial pain presented less severe levels of anxiety and depression than patients with only myofascial pain (p ≤ .01). The type of psychological instrument seems to affect the assessment of both anxiety and depression emotional states. Conclusion The findings of this review suggest that patients with myofascial pain are more anxious and more depressed than patients with other subtypes of TMD. Implications Considering that anxiety and depression are differently distributed within the TMD population, a proper assessment of the psychological state of patients seems essential to offer an adequate treatment and management of each specific subtype of TMD.

This report describes the 10-year follow-up data of a patient who underwent fragment reattachment to the maxillary central incisor after coronal fracture with pulp exposure as well as the procedures followed for functional and esthetic adjustments. A 9-year-old female patient presented at the clinic of dentistry at the State University of Rio de Janeiro with a coronal fracture and pulp exposure of the right maxillary central incisor that had occurred immediately after an accident. The intact tooth fragment was recovered at the accident site and stored in milk. The treatment plan followed was to perform direct pulp capping and tooth fragment reattachment. When the patient was 14 years old, adhesion between fragment and remaining tooth was lost, and fragment reattachment was performed. Five years later, the same tooth presented clinical discoloration and absence of sensitivity during pulp vitality tests. Subsequently, a new treatment plan was formulated, which included endodontic treatment, followed by nonvital tooth bleaching and light-cured composite resin restoration. An esthetic and natural-looking restoration was achieved. Tooth fragment reattachment is not a temporary restorative technique and requires functional and esthetic adjustments over time to maintain the biomimetic characteristics of traumatized anterior teeth and predictable outcomes.

Objective: To evaluate the dentists' knowledge about biosafety considering the SARS-CoV-2 and the risks of increasing the COVID-19 outbreak by dental practices during the pandemic in Brazil. Material and Methods: A cross-sectional study was performed by internet-based snowball sampling technique. A questionnaire with questions about different content was applied, and then analyzed the following two parameters: participants' Brazilian region and professional's specialty. Results: A total of 413 equestionnaires from all Brazilian regions were considered valid. There were no significant differences among biosafety measures adopted by participants from different Brazilian regions (p≥0.05), except for those from North region, which have applied less previous oral antisepsis, temperature screening, and specific anamnesis tracking COVID-19 symptoms (p<0.05). The unique use of N95 mask was positively associated with North region (p<0.05). Expert participants of Groups 2 (oral surgery and correlate areas) and 4 (orthodontics, oral radiology and facial jaw orthopedics) were more updated than other ones (p<0.05). Conclusion: The biosafety protocols applied by participants were not adequate for the epidemiologic status of COVID-19 in each region of Brazil, from 13th May to 17th June 2020. Specialties linked to microbiology area or structured social networks have better applied preventive measures for COVID-19.

Objetivo: Descrever as principais características clínicas e biológicas que interferem no planejamento das reabilitações orais envolvendo agenesia de incisivos laterais superiores permanentes e propor protocolos auxiliares para os planejamentos reabilitadores. Fontes de dados: As bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO) e PubMed foram consultadas empregando-se os operadores booleanos "AND" e "OR" entre os seguintes termos, "agenesis", "dental anomalies", "upper lateral incisor", "maxillary lateral incisor agenesis", "case study", "clinical studies", "case report", "review". Foram considerados artigos sem restrição de tempo e limitados aos idiomas português e inglês. Síntese dos dados: A agenesia dentária é comumente diagnosticada na prática clínica odontológica e um dos principais dentes acometidos por esta anomalia são os incisivos laterais superiores permanentes. Diferentes tratamentos reabilitadores têm sido descritos para as agenesias destes dentes, dentre os quais se destacam a abertura do espaço do incisivo lateral ausente com posterior reabilitação protética e o fechamento do espaço do mesmo dente através da mesialização dos dentes caninos e pré-molares com posterior reanatomizações de suas coroas clínicas. O tratamento mais adequado deverá ser definido a partir da análise de diversos fatores como, idade do paciente, perfil e padrão faciais, características do sorriso, oclusão, características anatômicas do canino, agenesia uni ou bilateral de incisivo lateral
