For treating deep caries lesions, selective or stepwise (one- and two-step) incomplete excavation seems advantageous compared with complete caries removal. By age 5, 23% of U.S. children have a cavity in a primary tooth. When the irritant is removed, the pulp has the capacity and potential to provide an up‐regulation of odontoblastic activity (reactionary tertiary dentinogenesis) or the recruitment of progenitor cells, which can cytodifferentiate into odontoblast‐like cells (reparative tertiary dentinogenesis). MANAGEMENT OF DEEP CARIES DONE BY., B. GLADSON SELVAKUMAR CRI., CSI CDSR 2. Selective carious dentine removal to soft dentine is performed to the extent that a temporary restoration can be properly placed. Alternatively, if the inflammation process is severe and ‘irreversibly’ damaged the only option is to completely remove the inflamed tissue. 2014). Recently, alternative MTA‐based materials, including Biodentine, have been developed, which have a reduced setting time (<15 min) and are recommended for one‐visit VPT procedures. 2009). 2009, Kim et al. Editors: Schwendicke, Falk (Ed.) Practically, it is challenging to place a capping material on a wet surface such as a blood clot, whilst the presence of a blood clot has been linked to higher risk of post‐operative infection (Schröder & Granath 1972, Schröder 1985). The demineralization is thought to be absent of bacteria as long as the dentine is not clinically exposed (Kidd & Fejerskov 2004). 2018). Clinically, the depth of caries and residual dentine thickness (Stanley et al. Other GFs including angiogenic molecules, such as fibroblast GF 2 (FGF‐2), vascular endothelial GF (VEGF), and placenta GF (PlGF) (Roberts‐Clark & Smith 2000, Tomson et al. Traditionally, deep caries management was destructive with nonselective (complete) removal of all carious dentine; however, the promotion of minimally invasive biologically based treatment strategies has been advocated for selective (partial) caries removal and a reduced risk of pulp exposure. (b) Carious lesion located at approximal site. Self-Limiting versus Rotary Subjective Carious Tissue Removal: A Randomized Controlled Clinical Trial—2-Year Results. 1967). The MTA is not packed into the pulpal cavity, but instead lightly tapped into contact with the pulp and dentine wall using a ‘thick paper’ point or cotton pledget. Symptoms may be present but not indicative of irreversible pulpitis. The most recent randomized controlled clinical trials in humans (Table 1) are limited by low numbers and resulting weak conclusions. D. ental caries remains a significant public health problem in the United States. 2010, Franzon et al. 1 Once Americans reach the age of 75, 99% will have had dental caries. Spec Care Dentist. Dentine and the pulp are one functional entity, the pulp–dentine complex (Pashley 1996); however, for diagnostic purposes at least, hard tissue (caries) and soft tissue disease (pulpitis) should be considered separately. Caries is the most common noncommunicable disease with a greater prevalence in patients from disadvantaged social groups (Whelton et al. The best known commercial Ca(OH)2 product is the hard‐setting Dycal® (Dentsply Sirona, Weybridge, UK), although nonsetting proprietary products are also used. 2006, Swedish Council on Health Technology Assessment 2010), rather than minimally invasive biologically based approaches aimed at maintaining the vitality of the pulp (Ricketts et al. In VPT, however, EDTA irrigation (although releasing DMCs) may stimulate renewed pulpal bleeding. Moving forward, treatment variation needs to be reduced, and therapeutic solutions should be cohesive and biologically based on a clear definition of a deep lesion as well as sound clinical evidence.

Understanding of pulpal repair mechanisms has highlighted the need for a low‐grade inflammatory process to stimulate the regenerative response (Cooper et al. If left untreated, caries will advance through dentine stimulating pulpitis and eventually pulp infection and necrosis; however, if conservatively managed, pulpal recovery occurs … Clinically, a focus on high‐quality primary research investigating the efficacy of management strategies for the treatment of deep caries is a priority. Superficial soft infected dentine was removed by bur and deeper located areas by chemo‐mechanical gel and hand instrumentation, but left at a residual level, whereby any added removal would lead to exposure. Find this issue and archived issues of the CDA Journal online. Notably, in class II procedures the use of high concentration of disinfection prior to placing the capping material is recommended as well as magnification to improve control of the carious removal procedure (Fig. 2009, 2015, Soden et al. If the pulp is exposed, the reparative dentine forms a mineralized bridge, which is generally not in the form of tubular dentine (Nair et al. 1992, Smith et al. Increasing evidence supports selective (“incomplete”) or stepwise instead of non-selective … It is easier to perform, as the consistency of the retained dentine has changed. 2015). and Fusobacterium spp. The goal of this narrative review was to summarize and compare treatment options for permanent teeth carious lesions that are radiographically close to the pulp chamber. Dental pulp cells (DPCs) when challenged by the presence of a carious microbial biofilm will directly respond by expressing a range of genes and proteins, promoting defensive cellular processes such as cell migration, proliferation and differentiation (Farges et al. Further clinical studies investigating molecular‐based assays are required to develop reliable diagnostic tools and better reproducibility. 2012) and cellular differentiation in vitro (Zanini et al. 1998). Partial pulpotomy removes 2–3 mm of the pulp tissue at the site of exposure; this technique is used for removing the superficial layer of infected or inflamed tissue. 1980). After removal of carious dentine. 1990, Machado et al. The ability to process sugars efficiently, to maintain sugar metabolism in an extreme environment (low pH) and produce intra/extracellular polysaccharides is important characteristics for cariogenic bacteria.

If left untreated, caries will advance through dentine stimulating pulpitis and eventually pulp infection and necrosis; however, if conservatively managed, pulpal recovery occurs even in deep carious lesions. 1973, Dummer et al. 2010). 2017). 1995). The prefix class II indicates that an altered treatment protocol is required, because a severe microbial challenge is expected. Furthermore, if the pulp is cariously exposed, can VPT procedures such as pulp capping or partial pulpotomy provide predictable outcomes or is more aggressive tissue removal or even RCT necessary? 2014b). 2016b) about the most appropriate management of deep asymptomatic carious lesions. These organisms are early colonizers (Nyvad & Kilian 1990) and may help establish an environment or niche, which mutans streptococci and lactobacilli will thrive in. 1982). Recent epidemiological data highlight that global prevalence has remained high over the last 25 years; however, the burden of untreated caries has shifted from children to adults (Bernabé & Sheiham 2014, Kassebaum et al. 2013). increasing carious involvement of dentine, pulp exposure) causes death of the primary odontoblast, which are subsequently replaced following differentiation of progenitor cells into odontoblast‐like cells under the regulation of bioactive molecules, including dentine matrix components (DMCs) release from the dentine matrix. Although the nature of the cellular response is likely to be dependent upon the pulp environment, the mineralized tissue deposited at the pupal wound site will likely display a spectrum of dysplasia. … 2017), but limitations including solubility, handling and biological response have led to the development of new materials such as hydraulic calcium silicates (Pitt Ford et al. 1982). 2015), partial pulpotomy (Taha & Khazali 2017) and full pulpotomy (Simon et al. From a scientific perspective, further understanding of the processes of inflammation, repair and material interaction is important to deepen understanding and develop novel diagnostic and therapeutic solutions. DMCs contain multiple bioactive components, including GFs, chemokines, cytokines, MMPs and bioactive proteins (Smith et al. Bio-Inductive Materials in Direct and Indirect Pulp Capping—A Review Article. 2017). 2013), and the neurogenic factors brain‐derived neurotrophic factor (BDNF) and growth/differentiation factor 15 (GDF‐15) (Duncan et al. Interestingly, the exact degree of carious lesion penetration has rarely been described in the literature in relation to VPT, including partial or full pulpotomy (Bjørndal et al. Conservative Management of Mature Permanent Teeth with Carious Pulp Exposure. Management of deep caries has traditionally been with complete (or nonselective) caries removal and in the event of pulp exposure root canal treatment (RCT) (Bjørndal et al. 2016a). In case of perforation a nested capping trial comparing direct pulp capping versus partial pulpotomy, Success: Pos. (b) Longitudinal mesial/distal crosscut of the same molar, exposing an occlusal enamel‐dentine lesion (insert C), and an extremely deep carious lesion originating from the proximal surface (insert D). requiring restorative intervention & … Like Contact CDA. Analysis of recent randomized clinical trials on the management of deep caries lesions (Table 1) highlights that inclusion criteria are similar with a defined caries lesion and signs of reversible pulpitis. 2015), a classification has been proposed, which a view to assisting clinical management (Bjørndal 2018).
