IntroductionWe are currently witnessing an increase in the number of disabled patients, creating the need for knowledge of each of the pathologies and of the different oral and dental conditions they present, in order to achieve efficient management and treatment.ObjectivesTo analyse the existing scientific literature on the oral conditions of children with autism spectrum disorder (ASD) and children with sensory deficits (SD), in comparison with the healthy child population.Material and MethodsThe bibliographic search was carried out in Pubmed/Medline, Scopus and Cochrane Library and included articles taking a sample of children between 0 and 18 years of age diagnosed with the abovementioned disorders and including at least one of the following oral hygiene conditions - oral hygiene, dental caries, malocclusion, oral habits, dental trauma, and gingival-periodontal status - comparing them with a healthy population.ResultsA total of 10 articles were obtained for autism spectrum disorder and six for sensory deficits.ConclusionsOf all the variables studied, only the state of oral, gingival and/or periodontal hygiene can be considered worse in patients with ASD and SD, although we believe a larger number of research studies is needed to corroborate these results. Key words:Oral health, dental caries, malocclusion, oral habits, dental trauma, oral hygiene, disabled child, autism, autism spectrum disorder, deaf, blind.

Several in vitro studies have shown that HIV-1 can infect CD4 negative epithelial cells of different origin including normal human oral keratinocytes, but whether this infection of mucosal epithelial cells occurs in vivo is still unclear. In this report, the presence and cell types infected by HIV-1 in paraffin embedded oral mucosa biopsies from 17 anti-HIV-1 positive patients have been examined by in situ hybridization and immunohistochemistry. As controls, oral mucosa biopsies from eight patients without HIV-1 infection markers were also analyzed. The results showed that 8 out of the 17 anti-HIV-1 positive patients had HIV-1 RNA detectable in plasma. Positive hybridization signals were observed in the mucosa biopsies from 14 of the 17 anti-HIV-1 patients (82.3%). The mean percentage of cells showing HIV-1 RNA was 2.64% +/- 1.77% (range: 1% to 5.5%). No differences in the mean percentage of HIV-1 infected cells were found between patients with and without HIV-1 RNA in plasma (3.01% +/- 1.57% vs. 3.4% +/- 1.27% respectively), or between untreated patients and patients under antiretroviral therapy (2.83% +/- 1.63% vs. 3.42% +/- 1.29% respectively). Immunohistochemical detection of S-100 antigen, cytokeratin and CD4 showed that hybridization signals appeared in cytokeratin positive cells and CD4 positive cells but not in S-100 positive cells. In conclusion, this study has demonstrated that HIV-1 infects and replicates in oral mucosa epithelial cells in vivo and that these cells could represent a reservoir of the virus that may escape to the currently used antiretroviral therapy.

Diversas técnicas convencionales han sido utilizadas con gran eficacia; sin embargo, la no aceptación de algunas de ellas por los padres, ciertos condicionamientos éticos y legales así como cambios en la educación actual y el avance en nuevas tecnologías, obligan al odontólogo a un replanteamiento de actitudes. Objetivo: El objetivo del presente trabajo es identificar qué técnicas alternativas son empleadas en la clínica dental por los profesionales para el manejo de la conducta de pacientes infantiles. Material y métodos: Se realizó un cuestionario en la plataforma de Google, remitido vía email a 190 odonto/estomatólogos que tratasen pacientes infantiles, obteniendo una participación de 132 encuestas adecuadas para el análisis de 6 técnicas alternativas de manejo de la conducta. El estudio estadístico se realizó en el programa SPSS aplicando el test de ANOVA para una significación de p= 0,05. Resultados: Un 35,1% de los encuestados utilizaban medios audiovisuales para el tratamiento dental, siendo la televisión el más frecuentemente empleado. La musicoterapia fue la técnica más utilizada (70,5% de los participantes) con mayor frecuencia del sexo femenino, aunque sin diferencias significativas, siendo la música moderna la de mayor aceptación. Un 32,8% utilizaron la ludoterapia como técnica de manejo seguida del empleo de técnicas de relajación con un 25%, ambas con mayor porcentaje femenino. Las dos técnicas menos utilizadas fueron la aromaterapia (6,8%) y la hipnosis (2,3%). Conclusiones: A pesar del incremento en la utilización de técnicas alternativas en el manejo de la conducta, todavía su empleo es escaso por los odonto/estomatólogos.  

Simulation, depending on the modality and fidelity of the scenarios, is an important resource for clinical teaching and achievement of learning outcomes in dentistry. The objectives of this study were to compare the degree of realism perceived by students and teachers in a simulated scenario, and to assess the level of competence acquired by the students. Method: In the Pediatric Dentistry course, eight clinical scenarios were carried out, each one using a modified Erler Zimmer child simulator (handmade), a professional actress and two students (dentist and assistant) on the same pediatric dentistry case consisting of a pulp abscess in tooth 8.5. A total of 114 students in the 4th year of dentistry studies participated in the pediatric dentistry course. Questionnaires with Likert-type answers were elaborated to evaluate the educational intervention, applying them before and after the simulation. Results: The realism best valued by the students was that of the simulated participant and the worst that of the manikin, the latter being strongly related to the realism of the office. It was observed that students' perception of clinical competence increased as the overall realism of the scenario increased (p-value = 0.00576). Conclusion: This research suggests that the creation of scenarios using handmade mannequins and simulated participants achieves a high level of realism, increasing the level of clinical competence perceived by dental students.
