The Assessment of a Minimally Invasive Procedure in the Treatment of Deep Carious Lesions: In vitro and In vivo studies

Schedule

Abstract:

Minimal invasive procedures in the management of deep carious lesions have been the focus of researchers in recent years. Minimal invasive procedures and the use of calcium silicate cement can maintain vitality in the compromised vital pulps by caries and trauma by providing good seals and enhancing favorable response and healing potential of the pulp to the injury in order to avoid the detrimental effect of devitalization of teeth. The effectiveness of an innovative minimally invasive indirect clinical pulp protection technique (including CarisolvTM gel chemomechanical system and an operating microscope) compared to a control protocol (rotary burs with no magnification) in preserving pulp vitality in symptomatic teeth in patients presenting with signs/symptoms of reversible pulpitis has been tested clinically over a period of one year follow up accompanied by a comprehensive detection of the microbiome associated with those deep carious dentin lesions. The excavation process alongside the restorative materials could have an influence on the infectivity and activity of the remaining bacteria in the dentine, by affecting their ecological stress factors like pH, oxygen, and nutrients. A randomized controlled clinical trial was undertaken which involved recruiting patients with signs of reversible pulpitis. Standardized clinical and radiographic investigations involving CBCT and PA radiographs at baseline and one-year follow-up were used to assess pulp pathology (presence/absence of PA radiolucencies). Bacterial load and composition of the bacterial flora were assessed using non-culture-based DNA extraction, qPCR, and sequencing of the 16S rRNA gene by using next-generation high throughput sequencing.
