Restoring carious lesions can be challenging, especially for deep lesions in proximity to the pulp. A number of factors can influence restoration longevity. This chapter will discuss aspects that should be considered when restoring carious lesions. In the first part, factors that might have an effect on the pulp such as preparation trauma, tooth hypersensitivity, and the use of liners will be described. In the second part, the challenges and limitations of adhesive bonding to (sound and carious) dentine will be discussed. Lastly, recommendations on the suitability of different bonding techniques and restorative materials in different situations will be given.
