The objective: the study analyses the features of spontaneous growth of hydroxyapatite crystals on dentinal substrate using (by the use of) artificially grown Zn-hydroxyapatite combined with ultrasonic treatment. Material and Methods. A dynamic study of dentinal substrate structure was conducted in a certain time interval after standard primary surface treatment of dentin micro-sections, divided into control and experimental groups. Dentin surfaces in the second group were covered by finely dispersed Zn-hydroxyapatite in combination with ultrasonic treatment. The investigation was performed by use of analytical complex based on scanning electron microscope with high resolution SEM Mira II LMU (Tescan) and energy dispersive analysis system. Results. There were revealed the structural changes of dentinal substrate surface overtime period due to directional growth of Zn-hydroxyapatite crystals. Conclusion. The conducted study showed the possibility of formation of the stable structures in the dentinal substrate when using Zn-hydroxyapatite in combination with ultrasonic treatment.
