Caries Susceptibility of Endodontically versus Nonendodontically Treated Teeth

A 20‐year historical prospective cohort study of root canal treatments. A Multilevel analysis

In the literature, nonrestorable carious lesions are reported as the main cause of extraction of teeth after root canal treatment (Zadik et al 2008), as these teeth are more caries susceptible than nonendodontically treated teeth (Merdad et al 2011) and may harbour a higher percentage of pathogenic bacteria on the surface of their larger (b) (c) (a) Figure 5 (a) Patient treated in 1992 for pulpitis of maxillary first molar (PAI 2) and second premolar (PAI 1); preoperatively, premolar had an infiltrated resin restoration; molar had an amalgam restoration with acute sensibility and distal caries lesion. (b) 10-year follow-up (2002): premolar was restored with composite resin (GIC + Composite group) and molar with metal-ceramic crown (Initial crowns group).…”

“…An initial distal carious lesion was observed on the second premolar (no apical radiolucency was observed). restorations (Merdad et al 2011). Two systematic reviews (Ng et al 2007(Ng et al , 2010 on tooth survival after root canal treatment highlighted the role of four parameters on the longevity of treated teeth: crown restoration, proximal contacts, abutment for prosthesis and tooth type, confirming the quality of coronal restoration as one of the most important factors influencing the outcome of root canal treatment.…”

MTA in Vital Pulp Therapy

“…This diminished protective mechanism in root canal-treated teeth might produce a higher incidence of coronal and radicular tooth fractures (Fuss et al 2001;Lertchirakarn et al 2003;Mireku et al 2010). Root filled teeth also exhibit an increased susceptibility to caries due to either substandard marginal integrity of restorations or a change in their biological environment (Merdad et al 2011). Furthermore, vital pulp procedures are conservative, comparatively simple and inexpensive treatments that do not require more complex and costly restorative care (Hørsted-Bindslev & Bergenholtz 2003).…”
