The biological reactions that take place in the dentine and the pulp during operative treatment of deep dentine lesions have been a subject of research of modern-day regenerative dental medicine. The minimal-invasive treatment of caries in dentine necessitates a non-aggressive, controlled excavation.
Aim: The aim is to establish the clinical protocol for minimal invasive approach in the treatment of dentinal caries of permanent teeth in children.
Material and methods: The object of the study were 60 dentinal carious lesions of permanent teeth in 60 children who were treated by stepwise excavation controlled by fluorescence method. The applied methodology enable us to store a large volume of tooth structure and activation of protective mechanisms of pulp-dentine complex. On the basis of treatments have been established clinical protocol for the minimally invasive approach in the treatment of deep dentine caries (stepwise method).
Results: The control of the excavation by fluorescence technique (Proface) provides the ability to perform gentle excavation. Excavation down to partially infected dentin assures that a larger volume of structures can be preserved, which enables processes of internal remineralization and reactive dentinenogenesis. Such lesions are treated in two sessions. In one session can be treated dentine carious lesions with characteristics of slowly progressive, with excavation down to affected dentine (through fluorescent control).
Conclusion: In minimally invasive approach for the treatment of deep dentine caries lesions were offered two options:
1.When affected dentin – dentine carious lesions can be treated in one session
2.When partially infected dentin dentin – dentine carious lesions can be treated in two sessions.
