The Potential of Hydroxyapatite Toothpaste to Prevent Root Caries: A pH-Cycling Study.

Purpose: The effectiveness of a hydroxyapatite (HAP) toothpaste and a fluoride toothpaste in preventing root tissue demineralization (root caries) was compared using an established pH-cycling caries model.

Materials And Methods: Sixty dentin blocks were produced from the root tissue of extracted human teeth and were assigned to 3 test groups (n=20/group): 10% hydroxyapatite toothpaste (HAP), 1450 ppm fluoride toothpaste (fluoride), and artificial saliva (artsaliva). Early root caries lesions were developed in each sample by 7-day demineralization using a pH-cycling caries model.

Prevalence of dental fluorosis among 12-15-year-old students in Enugu Metropolis, Nigeria.

Background: Excessive ingestion of fluoride during tooth development, particularly at the maturation stage, may result in dental fluorosis, with clinical implications. Literature is scarce on dental fluorosis in Enugu, Nigeria.

Purpose: The aim of this study was to assess the prevalence of dental fluorosis in Enugu, a major city in South East Nigeria.

Seatbelt use among drivers in an urban city in Nigeria: an observational study.

Studies from parts of Nigeria reported low compliance with seatbelt. This study sought to establish driver seatbelt use in Enugu, Nigeria by gender, vehicle type/use and time of day. Observations were done day and night at randomly selected locations.
