Currently, oral health issues are increasingly been addressed and virtual reality (VR) is being used as an aid in health areas. However, there is little evidence of VR being used in preventing oral health problems. To evaluate the effectiveness of VR in oral hygiene education. Three hundred pupils, aged between 9 and 12 years, received instructions in oral hygiene by immersion VR and they gave their opinions about the performed activities. Chi-square and Fisher's exact tests were applied, with a significance level of 5%. Part perception of oral hygiene showed no statistically significant difference (P>0.550). There was an increase in the use of dental floss (P<0.001), tongue brushing (P<0.001), and tooth brushing (P<0.001). Both drawings and comments made by participants related to oral hygiene were positive regarding the project. Conclusions: The use of VR in oral hygiene instruction was effective. Most participants increased brushing and flossing frequency and produced drawings related to oral hygiene. VR is effective and should be used in dentistry for teaching and prevention , especially with children, as it presents an interactive instructional space that can be approached in a playful way. This study presents dentists with a promising alternative for changing oral hygiene habits.
BACKGROUND Currently, oral health issues have been increasingly addressed, virtual reality (VR), being used as an aid in the health area. However, there is little evidence of the use of VR in preventing oral health. OBJECTIVE To evaluate the effectiveness of VR in oral hygiene education. METHODS Three hundred students, aged 9 to 12 years old received instructions in oral hygiene by immersion in VR and they opined about the performed activies. Chi--square and Fisher's exact tests were applied, with a significance level of 5%. RESULTS The participants' perception of oral hygiene showed no statistically significant difference (p=0.550). There was an increase in the use of dental floss (p=<0.0001), in tongue brushing (p=<0.0001), and in tooth brushing (p=<0.0001). The drawings performed by the participants demonstrated drawings related to oral hygiene and the messages were positive regarding the project. CONCLUSIONS The use of VR in oral hygiene instructions was effective. Most participants increased the frequency of tooth and tonghe brushing, of the use of dental floss, and made drawings related to oral hygiene.
Objectives: Permanent canines have an important functional role during mastication due to their anatomy,cbesides its relevance in oral esthetics. However, dentistry undergraduates have great difficulty in differentiating them during dental anatomy classes. The objective of this work was to study the morphology of the extracted permanent maxillary canines (MC) and lower canine (LC) in order to describe the anatomical similarities and differences.Methods: One hundred maxillary canines and 100 lower canines were evaluated. Measurements were performed using a digital caliper, and also visual analysis. The data obtained in each evaluation were submitted to descriptive statistical analysis, and the chi-square test and Fisher's exact test with a significance level of 5% were applied.Results: It was observed that the MC root groove was present on the two proximal surfaces and the groove depth was greater on the mesial surface, as reported in the literature. The MC incisal ridge was normally worn, and imprecision in dental differentiation could occur during the anatomical study, while it is stated that the incisal ridge allows distinguishing this tooth by a simple visual examination. The marginal ridges of the MC had a moderate prominence, as observed in the literature. The MC cingulum often presented a moderate prominence, contradicting some studies which reported a large cingulum. The presence of the cervicoincisal ridge on the lingual surface was frequently observed with moderate, absent or little prominence, while some authors reported that this structure is quite evident. Furthermore, it is reported that MC usually presents aforamen cecum, which was not observed in our sample. LC often presented a worn incisal ridge. The cingulum, marginal ridges, lingual fossa and developmental grooves were less evident and, in some cases, the lingual surface presented a flat shape, which is not usually reported in the literature.Conclusions: The morphological differences and similarities of MC and LC are important for a detailed anatomical study to help dentistry undergraduates identify them correctly. Furthermore, the anatomical study is important for the restorative area for an appropriate aesthetics and function rehabilitation.
