You also will understand the Clinical Classification of Pulp Pathology, the diagnostic aids used to diagnose pulp pathology, all techniques of pulp therapy with the most recent treatment modalities step by step for each type of treatment. 2007, Galler et al. (a) Deep carious lesion reaching pulpal quarter with a zone of dentine separating the lesion from the pulp (b) and extremely deep penetrating the entire thickness of the dentine. (a) Deep carious lesion reaching pulpal quarter with a zone of dentine separating the lesion from the pulp (b) and extremely deep penetrating the entire thickness of the dentine. Scientometric analysis of vital pulp therapy studies. It is accepted that an inadequate temporary restoration and lack of a permanent coronal seal during the less invasive carious removal strategies will lead to failure including pulpal and apical pathosis (Bjørndal & Thylstrup 1998, Maltz et al. Material Pulp Cells and Tissue Interactions. For many years, it was thought that the quality of the seal alone determined the success of the procedure (Bergenholtz et al. In this context, the majority of general practitioners selected the ‘deep’ carious dentine lesion as one that penetrates radiographically into the pulpal quarter of the dentine, but still with a well‐defined zone of radiopaque dentine separating the infected demineralized dentine from the pulp (Fig. This conventional pulp capping procedure (Schröder 1985) is indicated after a complicated traumatic fracture, which involves a superficial exposure of the pulp or after an accidental perforation (Bjørndal 2018).

TVH-19, a synthetic peptide, induces mineralization of dental pulp cells in vitro and formation of tertiary dentin in vivo. J Dent. 2017). 2012). Is it worth it? Furthermore, they are also able to pump out protons in an acidic environment and produce specific acid‐stress response proteins. Working off-campus? 2017). 2016a). 2017) and epigenetic modifying agents (Duncan et al. Management of deep caries and pulp capping Dr. Eason Soo DDS (UKM), MDS Endo (Hong Kong) AdvDipEndodont (Hong Kong), M Endo RCS (Edinburgh) Lecturer/Clinical Specialist … 2008, Marques et al. Best For: Anxiety. 2005, Karapanou et al. Reparative dentine formation involves a complex sequence of events in which a severe stimulus (e.g. Blood clots also contain numerous bioactive molecules (e.g. 1963a,b, Dummer et al. Notably from an endodontic viewpoint, a clear definition of lesion depth is lacking in many studies and the available evidence on well‐defined deep carious lesions in adult teeth remains limited. Although not the focus of this review, studies in the primary dentition have also shown that a one‐stage selective carious removal procedure performs successfully (Casagrande et al. 1995). 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. The resulting report may be associated with a more positive estimate of the intervention effect (Gluud. 2005). It is not possible to determine objectively the precise level of activity within a carious lesion; therefore, clinical judgement and subjective measures are used. Indeed, there is a wide range of reported success rates for pulp capping procedures after carious exposure. Chlorhexidine digluconate solution (2%) has been suggested as an alternative to NaOCl (Mente et al. 2008). 2006, Galler et al. 2013, Taha et al. Capping mat: ProRoot MTA (control) n = 23; versus Endocem n = 23, Stratification variable: Age and exposure site (occlusal or axial). Although a one‐stage selective caries removal technique saves on both clinical and patient time, another potential limitation is that if the patient moves to a new dentist it may appear that caries remains and further intervention may be suggested. Management of deep carious lesions in vital teeth is challenging. This could potentially indicate that the simple examination of lesion depths on bitewing radiographs is an opportunity to introduce a diagnostic tool for evaluating the risk of bacterial invasion into the pulp. 2006 that includes the additional concepts of dental caries management protocols. Notably, mutans streptococci possess multiple sugar transport systems including the phosphoenolpyruvate phosphotransferase system and can enzymatically thrive at a low pH. The resulting report may be associated with a more positive estimate of the intervention effect (Gluud. 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. This is more evident with traditional Ca(OH)2 materials compared with hydraulic calcium silicate cements (Nair et al. Notably, the dentine demineralization takes place in the zone of sclerosis and not sound dentine. The aim of the first stage is to change the cariogenic environment. 1963a,b, Garfunkel et al. 2016). However, the treatments vary from pulpotomy to extensive carious removal (indirect pulp capping) and stepwise excavation, which perhaps reflects that no global consensus or tradition currently exists in … 2005). 2000, de Soet et al. Established borders of a dental specialty may create traditions or obstacles for providing the best possible platform for optimal ‘pulpal care’. 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. Unfortunately, as odontoblasts are highly differentiated post‐mitotic cells, a new layer cannot be created, as in other connective tissues, by inducing mitosis of cells at the wound periphery. This long held view has, however, been questioned in a study, which compared clinical diagnosis with the histological findings, where the clinical diagnosis was made before the teeth were extracted and compared to histology post‐extraction (Ricucci et al. On the other hand, avoiding exposing the pulp lessens the risk of bacterial infection and preserves the odontoblast palisade to facilitate reactionary (or reparative) dentinogenesis. Indeed, a problem with pulpal biomarkers and MMPs in particular is that they are not just destructive in nature; they also increase the bioactivity and reparative capacity of DMCs by further digesting the extracts (Okamoto et al. An unsuccessful class II pulp capping. No restriction as to the pulp symptomatology was defined a priori, but given the focus of our review only studies investigating the man-agement of teeth where maintaining pulp vitality was an option were included. and you may need to create a new Wiley Online Library account. Stable renal function in children and adolescents with sickle cell disease after nonmyeloablative hematopoietic stem cell transplantation. As dental biofilm consists of commensal and noninvading microorganisms, the contemporary understanding, known as the ‘ecological plaque hypothesis’, suggests caries is a result of an ecologic imbalance within the dental biofilm with acidogenic and aciduric species dominating within the biofilm under frequent intake of carbohydrates (which are metabolized to acids) (Marsh 1994, 2003). Management of deep caries lesions with or without pulp involvement in primary teeth: a systematic review and network meta-analysis. Performance of a Biodegradable Composite with Hydroxyapatite as a Scaffold in Pulp Tissue Repair. At present, there remains a paucity of high‐quality randomized clinical trials comparing and testing capping materials in order to make definitive conclusions on the best material to use. Comparing the outcome of various strategies to treat deep caries is complex, and as a result, the debate about whether or not to preserve a layer of dentine continues. Other options include assessing the level of pulpal haemostasis as inflammation is associated with hypervascularization. Selected matrix metalloproteinases (MMPs), a family of tissue proteases, contained with the DMCs will propagate the breakdown of dentine matrix (Mazzoni et al. 1997, Smith 2003, Grando Mattuella et al. A systematic review on the subject (but with the same limitations as above) concluded the overall success rate is in the range of 72.9%–99.4% (Aguilar & Linsuwanont 2011). 2014a, Yoshiba et al. In particular, it is not possible to distinguish the delicate broader between infected and affected dentine both being discoloured and demineralized, which also explains the recently suggested simplified terminology on removal of carious tissue (see later). Editors: Schwendicke, Falk (Ed.) By age 5, 23% of U.S. children have a cavity in a primary tooth. 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. ), had an outcome of 32% dropping to below 10% after 5 years (Bjørndal et al. ; however, other taxa such as a novel Prevotella spp., Selenomonas spp., Dialister spp., Eubacterium spp. 2013). Working off-campus? Colour classification of carious lesions (modified from Bjørndal. review revealed that a majority of dentists and dental therapists would opt to. 1997). 1998). (e) Haemostasis is difficult to achieve. From a histopathological perspective, the threshold for irreversible pulpal inflammation can be defined as the stage where the cariogenic microorganisms are entering the pulp space either through tertiary dentine or directly into the pulp. 2016). In VPT, however, EDTA irrigation (although releasing DMCs) may stimulate renewed pulpal bleeding. A recent randomized clinical multicenter trial demonstrated that MTA performed better than Ca(OH)2 (Kundzina et al. Experimental (stepwise): 60% success. Long non‑coding RNAs are novel players in oral inflammatory disorders, potentially premalignant oral epithelial�lesions and oral squamous cell carcinoma (Review). It is recognized that this classification may of particular benefit to workers in primary care to assist decision‐making after exposure and that certain dentists (including specialists) may in fact use an enhanced protocol for the treatment of all pulp exposures. For treating deep caries lesions, selective or stepwise (one- and two-step) incomplete excavation seems advantageous compared with complete caries removal. 2012). 2018). The classical approach to treatment of deep carious lesions approaching the pulp mandates removing all infected and affected dentin. 1998). The demineralization is thought to be absent of bacteria as long as the dentine is not clinically exposed (Kidd & Fejerskov 2004).

Third European Society of Endodontology (ESE) research meeting: ACTA, Amsterdam, The Netherlands, 26th October 2018. While several systems were reviewed … 2012). 2016, Schwendicke et al. Selective caries removal strategies can be one‐visit as indirect pulp treatment or two‐visit using a stepwise approach. Ridell K, Olsson H, Mejare I. Unrestored dentin caries and deep dentin restorations in Swedish adolescents. Recent research on deep carious tissue management supports less invasive strategies, highlighting that complete removal of soft dentine to leave a thin barrier of residual dentine may not be necessary or desirable (Innes et al. Poor oral health status and short‐term outcome of kidney transplantation. Preserving pulp vitality is at the core of Operative Dentistry and offers a biological‐based concept, which reduces intervention and maintains the pulp's developmental, defensive and proprioceptive functions (Randow & Glantz 1986, Paphangkorakit & Osborn 1998, Smith 2002), whilst vital pulp treatment (VPT) is considered technically easier to carry out than pulpectomy and RCT (Stanley 1989). As enamel is a microporous solid, the carious process and response of the dentine–pulp complex can frequently start before it is breached (Brännström & Lind 1965, Bjørndal et al. A lesion that is still active but less so tends to be darker with a colour closer to brown; it is dry and firmer when probed. An estimate of the depth of a carious lesion can be made on a bitewing radiograph. A successful class II pulp capping. Approximately 75% of the teeth with deep caries have been found from clinical observations to have pulpal exposures. have found to be abundant in such lesions (Nadkarni et al. Clinically, a focus on high‐quality primary research investigating the efficacy of management strategies for the treatment of deep caries is a priority. Clinical efficacy and the antimicrobial potential of silver formulations in arresting dental caries: a systematic review. 2015), a classification has been proposed, which a view to assisting clinical management (Bjørndal 2018). The aim of this review was to summarize current views on the biological response to deep caries as well the diagnosis, classification and management of deep carious lesions and carious pulp exposures. 2. visit: (8‐12 weeks) Final exc. 2017) were also identified in dentine extracts. It is recognized that this classification may of particular benefit to workers in primary care to assist decision‐making after exposure and that certain dentists (including specialists) may in fact use an enhanced protocol for the treatment of all pulp exposures. These two types of failures could potentially have a different aetiology. Other factors likely to be important prior to undergoing class I pulp capping are small exposures (preferably <1 mm diameter), located in the coronal third of the pulp chamber ideally corresponding to a pulp horn (Fig. The stepwise excavation is an established technique and option for the treatment of deep caries lesions. The only way to rebuild the odontoblastic palisade is to recapitulate in situ the original developmental process (Goldberg & Smith 2004). 2011, Elsalhy et al. By age 19, 67% of children will have experienced tooth decay. Control (direct pulp capping): 6% success. The painful tooth: mechanisms, presentation and differential diagnosis of odontogenic pain. Unfortunately, at present from a patient perspective, the critical factor in the treatment chosen by the dentist is whether the operator is pulp ‘friendly’ or not. 2017). 2001, Slaus & Bottenberg 2002, Bjørndal & Reit 2005, Markvart et al. As reported in the 1980s and 1990s in Sweden, occlusal lesions requiring invasive treatment established before the age of 12 years and leveled off in late adolescence. An experimental clinical study, Periapical fluid RANKL and IL‐8 are differentially regulated in pulpitis and apical periodontitis, Biological markers for pulpal inflammation: a systematic review, The relationship of bacterial penetration and pulpal pathosis in carious teeth, Immune cells and molecular networks in experimentally induced pulpitis, Operative caries management in adults and children. One randomized clinical multicentre study, based in a clinical general practice environment (without the use of a class II equipment such as the operating microscope, etc. Management of Deep Carious Lesions. 2015), partial pulpotomy (Taha & Khazali 2017) and full pulpotomy (Simon et al. 5). Several studies have investigated inflammatory pulpal biomarkers and their potential use as a diagnostic test (Nakanishi et al. Contemporary therapeutic approaches of carious lesions prioritize the preservation of pulpal health in vital teeth with deep caries lesions [].To achieve this goal, selective removal of soft dentin over the pulp has been indicated, while cavity margins (i.e., peripheral dentin from lateral walls) are left hard (scratchy) []. The CDA Journal is an award-winning peer-reviewed scientific publication that keeps dentists up to date about scientific advances, business management strategies and new products. 1998). A consensus document recently defined deep caries as radiographic evidence of caries reaching the inner third or inner quarter of dentine with a risk of pulp exposure (Innes et al. When caries ceases to be active and is thought to have arrested, these features will be more marked; therefore, it is darker, no excess moisture is present, and it is not possible to penetrate with a probe (Fig. By age 19, 67% of children will have experienced tooth decay. 2017), angiogenesis (Roberts‐Clark & Smith 2000), mineralization (Tomson et al. Furthermore, by having direct access to the tissue, it is easier to evaluate the health of the pulp and to manage it, for example pulpal bleeding. Caries prevalence remains high throughout the world, with the burden of disease increasingly affecting older and socially disadvantaged groups in Western cultures. radiograph, pulp sensibility testing) are added to the scenario. Analysis of the literature highlights that two types of failure may be occurring: (i) early failure within days of the treatment and leading to symptomatic pulpitis, and (ii) long‐term failures detected several months later and characterized by the presence of an apical lesion related to root canal infection after pulp necrosis. 2017). 1990, Machado et al. Editors: Schwendicke, Falk (Ed.) It is also not clear from this study the reason for the extraction of teeth with only reversible disease. 2002), undifferentiated mesenchymal cells from cell‐rich and central pulp perivascular regions, that is pericytes (Fitzgerald et al. response to pulp test at follow‐up. In addition, dentistry perhaps needs to embrace and develop next‐generation diagnostic devices to accurately determine the inflammatory state of the pulp. Questionnaire‐based surveys in which dentists study radiographs of ‘deep carious lesions’ have analysed the dilemma of whether a tooth should be treated conservatively by avoiding pulp exposure, or a VPT approach or whether a more invasive approach is required. The best known commercial Ca(OH)2 product is the hard‐setting Dycal® (Dentsply Sirona, Weybridge, UK), although nonsetting proprietary products are also used. For bacteria to play a role in the carious process, they must possess certain characteristics that promote the disease (Loesche 1986). A more accurate impression of the extent of a lesion can be given on a cone‐beam computed tomograph (CBCT); however, this has limitations such as the higher dose, image distortion due to the presence of radiopaque restorations, cost and availability. Bioceramic Materials in Clinical Endodontics. with deep carious lesions. Assessing the pulpal status of primary teeth can be the most difficult part of vital pulp therapy.
