The COVID-19 pandemic has had an immediate and dramatic impact on dental education.

The French version of the GOHAI exhibits satisfactory psychometric properties but two items (one about swallowing, the other with complex sentence structure) had poor stability.

The Child-OIDP index is an indicator of oral health-related quality of life, which has been validated among 12-yr-old children in Thailand. The aim of this study was to assess the reliability, validity, and applicability of this questionnaire among French children. After translation and cultural adaptation, the Child-OIDP was tested on 414 10-yr-old children in France. The children completed the Child-OIDP in face-to-face interviews, were clinically examined, and answered questions evaluating their global self-rated oral health. Parents filled in a questionnaire concerning their socio-demographic background. An oral impact on daily life was reported by 73% of the children. The mean Child-OIDP score was 6.32 [standard deviation (SD) 8.22] and the median was 3.33. The internal reliability was confirmed with a Cronbach's alpha of 0.57. The retest procedure (n = 62) showed a satisfactory reproducibility (r = 0.81, kappa = 0.75). The index was shown to be a valid instrument. Construct validity was satisfactory as the Child-OIDP score increased when the children's perceived oral health decreased. The Child-OIDP score was able to discriminate between different socio-demographic groupings and varied according to dental status. This study showed that the Child-OIDP is applicable for use among children in France. It has promising psychometric properties but further research is required to evaluate its sensitivity to change.

This review aimed to determine the association between periodontal disease and stroke incidence by a meta-analysis of cohort studies. Cohort studies that evaluated the incidence of stroke (fatal or non-fatal, ischaemic or haemorrhagic) and baseline periodontal status and calculated relative risk values were included. The quality of the included studies was assessed using an evaluation grid. The analyses were conducted separately for three outcomes: periodontitis, gingivitis and loss of teeth. Adjusted values of relative risk or of hazard ratio were used to assess risk values in each study. Random effects meta-analyses were conducted when data could be pooled. From the 743 references retrieved, only nine cohort studies were suitable for inclusion in this review. Quality scores of the studies varied greatly. Three prospective studies, which used reliable indicators of periodontal disease, obtained the highest scores. Conversely, three studies that used a subjective evaluation of stroke incidence or diagnosed stroke without imaging obtained the lowest score. The results of the meta-analyses varied depending on the outcome considered and the type of stroke. The risk of stroke was significantly increased by the presence of periodontitis [relative risk 1.63 (1.25, 2.00)]. Tooth loss was also a risk factor for stroke [relative risk 1.39 (1.13, 1.65)]. The risk of stroke did not vary significantly with the presence of gingivitis. This review shows that periodontitis and tooth loss are associated with the occurrence of stroke.

The GOHAI can be used to evaluate needs for and effect of the making of new complete dentures.
