If the pulp appears infected or symptomatic, the dentist may decide a root canal is the best treatment option. In cases of direct pulp capping, a continuous hard tissue barrier determined by direct clinical ex-amination and a positive response to electric pulp tester stimulation. In conclusion, MTA has a higher clinical success rate for direct pulp capping JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, Revista de la Asociación Odontológica de Costa Rica. The expression levels of collagen type I and HSP47, collagen-binding stress protein, were analysed by real-time PCR. 0000006806 00000 n This method seems able to allow the analysis of cell activity (start, activation, blocking). 0000444549 00000 n HSP47 protein expression was examined by Western blotting. The aim of this article is to summarize and discuss various pulp capping materials. In the present study, to elucidate the mechanism behind the anti-inflammatory effect, we examined the effects of low-power neodymium-doped yttrium-aluminium-garnet (Nd:YAG) laser irradiation on interleukin (IL)-6 expression in human pulp (HP) cells stimulated by peptidoglycan (PGN) and focused on intracellular signaling pathways. Bjorndal, L. et al. 0000018177 00000 n All of the Dycal and Durelon-capped pulps were successful at both time intervals. Statistical analysis was performed using one-way analysis of variance (anova) followed by the Tukey's multiple comparison test. 0000435444 00000 n They should be bacteriostatic and bactericidal, Various Materials Used For Direct Pulp Capping, drawn to disinfecting agents, because it became o. for pulp inflammation - but these agents were cytotoxic. 0000020349 00000 n The response of the dentin–pulp complex in rat teeth was investigated after direct capping with biodentine with or without bone marrow‐derived stem cells (BMDSCs). Caplan DJ, Cai J, Yin G, White BA. the direct pulp capping is not suitable for carious opened pulp with reversible pulpitis but recommend more investi-gations in this direction which could change the current opinion [8]. 0000005969 00000 n Embed. 0000015973 00000 n 0000021047 00000 n Int Endod J., 2009; 42(10): 940, human pulp cells. The cell viability was not affected by laser irradiation at 2 W for up to 40 s. However, it was significantly decreased by 20% at 60 s (P < 0.05). 0000021026 00000 n Caries Res. Clin Orthop Relat Res., 1993; 295: 305, like growth factor I (rhIGF-I) in rat molars. Surgically exposed, infected permanent teeth of monkeys were capped with four agents. Vital pulp therapy procedures can treat the decay approximating the pulp to avoid the pulp becoming infected or being. March 2018: 39 (3): 182-189. Vital pulp therapy procedures are material can decrease the rate of healing and bridge still practiced and taught in dental schools as formation. Bridging was complete in only three of the Durelon-capped pulps. 7. Thus, suppression of the phosphorylated p38 activity by low-power laser irradiation in HP cells culminates in inhibition of the increase in IL-6 induced by PGN, suggesting that low-power laser irradiation regulates intracellular signaling molecule activities to exert its anti-inflammatory effect. Educational video for dental students and dentists on the Direct Pulp Capping procedure. The often-repeated claim that calcium hydroxide compounds exert a persistent stimulating effect on the pulp resulting in its eventual obliteration was not supported. Brown-Brenn staining revealed no bacterial microleakage at both time points. 0000006877 00000 n Direct puip capping The cleaner tooth surface could also conceivably allow better adaptation of the restorative material and hence reduce microleakage (37). Direct pulp capping is used when the pulp is visibly exposed (vital pulp … Low-power laser irradiation inhibited the activity. Microscopic study after 30 and 90 days revealed considerable success in teeth treated with a mixture of vancomycin and calcium hydroxide, or with calcium hydroxide and methyl cellulose. The indications, clinical factors, materials and treatment procedures are considered along with the expected prognosis. 6. The dentin exposed to a density of energy of: 2 X 10(3) J/cm2 shows a burn, a rarefaction and a cellular degeneration, followed by a neoformation of calcified dentin, of about 300 microns thick in 3 months, due to the excitation of odontoblasts or produced by pulpal cells functioning before. 2004; 38(3):314–20. Background. 0000001993 00000 n In this histological study, 19 human teeth were mechanically exposed and the pulps were capped with isobutyl cyanoacrylate. A density of energy of 10(3) J/cm2 order applied to the pulp beads to its partial necrosis, to various inflammatory aspects and to a quasi-constant regeneration by a neo-dentin bridge of 200 microns at 1 month. The presence of calcium ions stimulates precipitation of calcium carbonate in the wound area and thereby contributes to the initiation of mineralization. EC Dental Science 13.2 (2017): 75-83. The teeth were extracted from one monkey 23 months after capping and from the other monkey 29 months after capping. 0000002557 00000 n 4. 0000012314 00000 n Email.

The mineralization of the collagen starts with dystrophic calcification of both the zone of firm necrosis and the degenerated cells in the adjacent tissue, leading to deposition of mineral in the newly-formed collagen. 0000002328 00000 n In 1970, Langer et al. Their formation following direct pulp capping. 0000467869 00000 n Traumatic inflammation due to application of CO2 laser radiation (lambda = 10.6 microns) on the dentin and on pulp of 342 teeth of 8 dogs (Beagle) and of 6 monkeys (Macaca sp. 0000456895 00000 n The treatment of these pulp conditions often results in extraction or root canal therapy. The pulps were then capped with either Keflin (an antibiotic), Durelon (a polycarboxylate cement), or Dycal (a calcium hydroxide compound). laser irradiation stimulated mineralization in dental pulp cells. [1] Pulp treatment modality can be classified to 2 categories. After a dentin exposure to a density of energy from 2 X 10(3) J/cm2, the first cell layers of the pulp tissue show a rarefaction and a cellular degeneration, followed by a neoformation of calcified dentin, of about 300 microns thick in 3 months, due to the excitation of odontoblasts or produced by pulpal cells functioning before. Reason. It includes the application of a biomaterial directly onto the exposed pulp, followed by immediate 0000468856 00000 n Ideal Requirements of Pulp Capping Material (As Suggested By Cohen And Combe), The materials should be radioopaque and have good bacterial seal. 0000007640 00000 n Direct pulp capping is defined as a wound dressing of the exposed clinically normal pulp with the absence of signs and symptoms of severe pulpal disease. The procedure of pulp capping relies primarily on the ability of pulpal tissue to heal. Pulp exposed after a deep carious lesion may be treated by bioactive molecules or by differentiated pulp cells. were the first to evaluate, have reported high success rates, which ranged from 93%, Another study of indirect pulp capping on rat molars concluded. A wide array of materials has been used for pulp capping. RESULTS: The clinical aspect of direct pulp capping during the operation was satisfactory, and all patients were asymptomatic in the postoperative phase. Pulp protection is the term coined by AAPD which recommends the placement of a protective base or a liner on the pulpal and axial walls of the cavity preparation to act as a protective barrier between the restorative material and the tooth. 0000451066 00000 n When a pinpoint mechanical exposure of the pulp is encountered during cavity preparation or follow-ing a traumatic injury, a biocompatible radiopaque base such as MTA41-44 or calcium hydroxide45 may be placed in contact with the exposed pulp tissue. The choice of an appropriate restorative material to reduce bacterial microleakage can increase the success of direct pulp capping (19, 38-40). Pulpotomy. Direct Pulp Capping: Here the protective dressing is placed directly above an exposed pulp. The anti-inflammatory effects of low-power laser irradiation have previously been reported. 0000018156 00000 n 0000020295 00000 n The extracellular collagen production was significantly increased by 73% on day 2 and 38% on day 4 after laser irradiation (P < 0.05). Pulp treatment modality can be classified to 2 categories. %PDF-1.3 %���� 0000016728 00000 n The exposed pulp surface was then washed with physiological saline. Direct capping is effective when it is carried out on a pulp exposure, revealing an initial opening of a pulp horn, and accompanied with bacterial invasion. A direct pulp cap is done on permanent teeth when the removal of deep decay results in exposing the pulp. ionomer also provides an excellent bacterial seal and shows, agent exhibited chronic inflammation and lack of dentin. 0000018851 00000 n If this lesion is not treated properly, the caries can approximate the pulp resulting in pain and infection. weeks after direct pulp capping. Direct pulp capping was performed with reference to Dianat et al. Your name. These procedures are indicated for primary, immature permanent, and mature permanent teeth in children and adolescents. 0000469867 00000 n A p38 mitogen-activated protein kinase inhibitor, SB203580, also inhibited the increase in IL-6 messenger RNA levels.
