Parent perceptions regarding virtual pediatric dental clinics during COVID-19 pandemic: a cross-sectional study

Objective

To assess the attitudes and responses of parents of pediatric patients towards virtual dental clinics during COVID-19.

Material and Method

A total of 102 parents of pediatric patients who were scheduled for virtual (video or telephonic) clinic appointments for new patient consultations and follow-up clinics were included in the study. Parents and patients could attend the virtual clinic from a personal computer, tablet, or smartphone. An electronic self-administered questionnaire was sent to the parents through email after consultation (video or telephonic) which consisted of demographic data and a ten-item, five-point Likert-scale assessing: (i) parent satisfaction; (ii) ease of use; (iii) the effectiveness including increasing access to clinical services; (iv) reliability of the teledentistry system and (v) usefulness for patients. Statistical analyses used were t-test, one-way ANOVA test, Shapiro-Wilk and histogram.

Result

Out of 102 parents, 52 attended video clinics and 50 attended the telephonic clinic. The majority of the parents were between 30-39 years of age, and about 73% had no previous experience with either virtual or telephonic consultation. Ninety-four percent of parents were satisfied with vide clinic consultation, and most of them agreed that accessing clinical services through a video clinic was easy to understand, comfortable, and time-saving. The majority of the parents (94%) agreed and strongly agreed that they will use video clinics again in the future for consultation.

Conclusion

Parents' response to the use of virtual clinics for pediatric dentistry during COVID was positive. The majority of the parents stated that they would consider using teledentistry for future consultation.

Comparison of a Smartphone-Based Photographic Method with Face-to-Face Caries Assessment: A Mobile Teledentistry Model

OBJECTIVES

This study sought to evaluate the efficacy of a mobile teledentistry approach using a smartphone camera for remote screening of dental caries.

MATERIALS AND METHODS

An image acquisition Android App was created to facilitate the acquisition and transmission of dental images to a store-and-forward based telemedicine server. One hundred participants who were attending routine checkups at dental clinics were enrolled in 2014. Following a face-to-face oral screening by a screener (dentist), images of patients' teeth were obtained using a smartphone camera. These images, along with patient information, were then transmitted from the Android App to the server through the Internet for later independent assessment by two charters (off-site dentists). The assessments of these charters were then compared to the benchmark face-to-face caries assessment.

RESULTS

Sensitivity values for the photographic method when compared to the benchmark face-to-face caries assessment were moderate, and ranged from 60% to 63%. Weighted kappa (K) as a measure of intragrader agreement for the photographic assessment was estimated as almost perfect (K = 0.84). The intergrader agreement for the photographic method compared to the face-to-face caries assessment ranged from moderate to substantial (K = 0.54-0.66).

CONCLUSIONS

Despite some limitations, the mobile teledentistry approach has shown the potential to detect occlusal caries from photographs taken by a smartphone camera with an acceptable diagnostic performance compared to traditional face-to-face screening. This study suggests that telemedicine and cellular phone technology can be combined to create an inexpensive and reliable screening tool.
