Effects of Chlorhexidine Cavity Disinfection on Adhesive Restorations

Title : Effects of Chlorhexidine Cavity Disinfection on Adhesive Restorations


Chlorhexidine (CHX) is a broad spectrum antimicrobial which is used in many aspects of dentistry. The shift towards minimally invasive restorative practice has led to clinicians to preserving as much tooth structure as possible and maintaining a layer of caries affected dentine, especially in deep cavities encroaching near the pulp.
Remaining bacteria can be responsible for secondary caries, sensitivity, and ultimately failure of the restoration. Furthermore, the increasing popularity of composite resin restorations instead of amalgam, means that the science of bonding needs to be considered more carefully as these restorations do not rely primarily on macro-mechanical retention.
CHX as a cavity disinfectant has the potential to reduce bacterial load and potentially improve composite bond strength when used correctly, however if it is applied without assessing all the materials and without using the appropriate bonding protocol, it could have a negative impact on the restoration. This poster will highlight the cases where it has shown to improve bond strength, and the protocols where it can actually weaken the integrity of the restoration.
Other cavity disinfectants like lasers, sodium hypochlorite and hydrogen peroxide are lesser known alternatives to CHX, however also have their own limitations, and will be discussed in this poster.



Dr Claire Dewshi graduated from King’s College London, England, in 2019 and continued to pursue further training years in secondary care following Foundation Training in South-West London. Having worked in a Maxillo-facial unit in Sussex and then a Restorative Dental Unit in Swansea, Claire has had the opportunity to see how head and neck cancer patients are treated surgically, and subsequently restored dentally under the care of a multidisciplinary team.
She has a passion for dental education and mentorship which has led her to becoming involved with dental charities and widening participation groups to improve access to dental schools.
