Intervention and control
The trail started at 03/11/2021. Participants in the SG received information regarding oral health during pregnancy using the Snapchat mobile application. The oral health information was retrieved from previous studies [The stories were presented as a diary of the research team members, like most of the stories on Snapchat. The research team performed roles within the clinic of the dental teaching hospital at Umm Al-Qura University for dental chair settings, precautions with radiographs, materials that are likely to be used during dental treatments, and demonstration of dental flossing and toothbrushing. The participants received the content spontaneously throughout the intervention days. At the same time, the CG received the same information in a written flyer sent only once via WhatsApp.
