Early information on public health behaviors adopted to prevent the spread of coronavirus (COVID-19) may be useful in controlling the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) transmission. The objective of this study was to assess the role of income level (IL) and the perception of older adults, regarding COVID-19 susceptibility and severity, on adopting stay-at-home preventive behavior during the first week of the outbreak in Mexico. Participants in this cross-sectional study were urban community dwellers, aged ≥ 65 years from Mexico City. A total of 380 interviews were conducted over the phone. The mean respondent age was 72.9 years, and 76.1% were women. Over half (54.2%) of the participants perceived their susceptibility to COVID-19 as very low or low. Similarly, 33.4% perceived COVID-19 severity as being very low or low, and 57.6% had decided to stay at home: this behavior was associated with IL (β = 1.05, p < 0.001), and its total effect was partially mediated (15.1%) by perceived severity. Educational attainment was also associated with staying at home (β = 0.10, p = 0.018) and its total effect was partially mediated (15.0%) by perceived susceptibility. Interventions aimed at low income and less educated older adults should be developed to improve preventive behaviors in this vulnerable group during the COVID-19 pandemic.

Introduction Little is known about the state of oral health among immigrants from conflict zones, such as the refugee children from the Syrian Civil War. Aim To determine the oral health status of Syrian immigrant children refugee at the Center for Temporary Stay of Immigrants in Melilla to plan prevention and care programs. Design Using the criteria set by the World Health Organization, an exploration of the oral cavity of all Syrian children aged 5–13 living at that center was conducted in May 2015. All subjects were clinically evaluated by a calibrated and standardized examiner, accompanied by a dentist who registered the clinical variables, and translators. The sociodemographic and clinical variables were analyzed through a descriptive and analytical study, respectively. Results The prevalence of caries in both the permanent and deciduous dentition was 75% and 50% in 6- and 12-year-olds, respectively. The dft was 3.2 ± 2.9 in 6-year-old children. At 12 years old, the DMFT was 1.6 ± 2.6 teeth, the DMFM was 1.1 ± 1.7 teeth, the SiC was 3.2, and the IR was 5%. Eighty-six percent of the examined sextants were periodontally healthy. Conclusions The prevalence of caries was high in the sample population studied, confirming the need for a comprehensive primary oral health care program.

Clinicians should appreciate the effectiveness of virtual reality (VR) headsets for managing both the anxiety and the behaviour of non-cooperative paediatric patients who require treatment over several dental appointments. The aim of this study was to assess the effectiveness of using a VR headset as a distraction for managing the anxiety and behaviour of paediatric patients during their dental treatment. Eighty patients, aged between five and ten years old and who required dental treatment over three or more appointments, were randomly allocated into two groups. One group used a VR headset during all their appointments, and the other one did not use any distraction technique. The patients were asked to take a Facial Image Scale Test during their first and last appointments to assess their level of anxiety. Additionally, the dentist completed the Frankl Test to quantify the child’s behaviour at the beginning and the end of their treatment. The results obtained, both from the group using the VR headset and from the control group, were compared using the chi-square test. The use of a VR headset during dental treatment significantly reduced anxiety (95% of the children were happy) and improved behaviour (100% positive behaviour) as compared with the control group (40% and 57.5%, respectively). A VR headset can effectively distract a paediatric patient, helping to reduce anxiety and manage behaviour during dental treatment

Background Little information is available on the trends over time of the prevalence of molar incisor hypomineralization (MIH). This condition may be preventing dental caries decline. Aim (a) To compare the prevalence of MIH, in Mexico City schoolchildren, evaluated in 2008 with a group evaluated in 2017, (b) to identify the association of MIH with dental caries, and (c) to assess the mother's perception of her child's oral health status. Design Two cross‐sectional studies performed in 2008 and in 2017 were compared. The oral examiner and the selected schools were the same in both surveys. Results A total of 549 schoolchildren were evaluated. The prevalence of MIH in the first survey was 20.3%, and 31.9 % in the second survey, (p = .002). Children with MIH were more likely to have dental caries. The odds ratio was 2.24 (p = .036) and 4.18 (p ˂ .001) in the first and second surveys, respectively. Mothers of children with MIH perceived worse oral health status of their children than the mothers whose children did not have MIH (odds ratio = 4.47, p ˂ .001). Conclusion The findings portray a clear increase in prevalence of MIH and highlight the need for increased awareness about this condition among dentists and the general population.

BRONJ occurred significantly in patients who underwent dental extractions after the initiation of ZA and did not accomplish a preventive dental program.
