Objective. This study presents a clinical and histological evaluation of human pulp tissue responses after direct capping using a new dentin adhesive system. Methods. Twenty-eight caries-free third molar teeth scheduled for extraction were evaluated. The pulps of 22 teeth were mechanically exposed and randomly assigned to 1 of 2 groups: Single Bond Universal or calcium hydroxide. Another group of 6 teeth acted as the intact control group. The periapical response was assayed, and a clinical examination was performed. The teeth were extracted after 6 weeks, and a histological analysis was performed. The pulp status was assessed, and the thickness of the dentin bridge was measured and categorized using a histological scoring system. Results. The clinical phase was asymptomatic for Single Bond Universal patients. Patients in the calcium hydroxide group reported mild symptoms of pain, although the histological examination revealed that dentin bridges with or without limited pulpitis had begun forming in each tooth. The universal adhesive system exhibited nonsignificantly increased histological signs of pulpitis (P>0.05) and a significantly weaker thin mineralized tissue layer (P<0.001) compared with the calcium hydroxide group. Conclusion. The results suggest that Single Bond Universal is inappropriate for human pulp capping; however, further long-term studies are needed to determine the biocompatibility of this agent.

Background: Cellular response of dental pulp to existing lesions, caused by infiltration of inflammatory cells that migrate from blood vessels to the site of injury. Macrophages are the cells that most appear when inflammation occurs. Treatment for maintaining pulp tissue vitality is called pulp capping. Calcium hydroxide as a pulp capping material has the ability to trigger the growth of dentin bridges or remineralization, but calcium hydroxide can induce migration and proliferation of inflammatory cells. Currently the field of dentistry is developing propolis as an alternative pulp capping material. That is because propolis has anti-inflammatory properties. Objective: To analyze the effect of the combination of calcium hydroxide-propolis on the number of macrophage cells in the teeth of wistar rats with pulp perforation. Method: This study used 30 samples of Wistar rats which were preparated until perforation and then divided into 3 groups. The first group continued with filling with cention, the second group continued with application of calcium hydroxide and filled with cention, and the third group continued with the application of combination of calcium hydroxide and propolis and then being filledwithcention. Macrophage cell is calculated histopathologically by using compound light microscope on the 3rd day with 400x magnification. Results: The Kruskal-Wallis test results showed significant differences in macrophages after the combination of calcium hydroxide and propolis (p = 0,000). The combined application of calcium hydroxide and propolis showed higher macrophages than the application of calcium hydroxide and the control group. Conclusion: Application of calcium hydroxide - propolis combination was proven increase the number of macrophage cells in Wistar Rats (Rattus Norvegicus) with pulp perforation

Background: Propolis is a substance made from resin collected by bees (Apis mellifera) from variety of plants, mixed with its saliva and various enzymes to build a nest. Propolis has potential antimicrobial and antiinflammatory agents with some advantages over calcium hydroxide (Ca(OH)2). Ca(OH)2 has been considered as the “gold standard” of direct pulp-capping materials, but there are still some weakness of its application. First, it can induce pulp inflammation which last up to 3 months. Second, the tissue response to Ca(OH)2 is not always predictable. Third, the tunnel defect can probably formed in dentinal bridge with possible bacterial invasion in that gap. Purpose: This study was aimed to determine and compare the thickness of odontoblast-like cells layer after induced by propolis extract and Ca(OH)2 in rat’s pulp tissue. Method: Class 1 preparation was done in maxillary first molar tooth of wistar mice until the pulp opened. The Ca(OH)2 and propolis extract was applied to induce the formation of odontoblast-like cells, the cavity was filled with RMGIC. The teeth were extracted (after 14 and 28 days of induction). The samples were then processed for histological evaluation. Result: There were significant differences between the thickness of odontoblast-like cells after induced by propolis extract and Ca(OH)2. Conclusion: The propolis extract as the direct pulp capping agent produces thicker odontoblast-like cell layer compared to Ca(OH)2.

The Effects of Hyaluronic Acid, Calcium Hydroxide, and Dentin Adhesive on Rat Odontoblasts and FibroblastsThe aim of this study was to investigate the effects and efficiency of pulp capping preparations based on hyaluronic acid, calcium hydroxide, and dentin adhesive on the pulp tissue of Sprague-Dawley rats. The rats were killed and extracted teeth sectioned transversely through the pulp. The slices were placed in a RPMI 1640 cell culture medium supplemented with 10 % foetal calf serum. During 14 days of cultivation cultures were treated with preparations that contained hyaluronic acid (Gengigel Prof®), and calcium hydroxide (ApexCal®), or with dentin adhesive (Excite®). Cellularity and viability of fibroblasts and odontoblasts was analysed using a haemocytometer. Hyaluronic acid proved most efficient and the least toxic for direct pulp capping. Even though calcium hydroxide and dentin adhesive demonstrated a higher degree of cytotoxicity, their effects were still acceptable in terms of biocompatibility.

Summary Introduction Direct pulp capping is an important therapeutic method that has goal to provide formation of dentin bridge and healing process of the pulp. The aim of this study was to investigate the effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite on exposed dental pulp in Vietnamese pigs. Material and Methods The study was conducted on 30 teeth of two Vietnamese pigs (Sus scrofa verus). On buccal surfaces of incisors, canines and first premolars, class V cavities were prepared with a small round bur and pulp horn was exposed. In the first experimental group (10 teeth) the perforation was covered with new nanostructural material based on calcium silicate systems (CS). In the second experimental group, the perforation was covered with compound of calcium silicate systems and hydroxyapatite (HA-CS) (10 teeth). In the control group, exposed pulp was covered with Pro Root MTA® (Dentsply Tulsa Dental, Johnson City, TN, USA) (10 teeth). All cavities were restored with glass ionomer cement (GC Fuji VIII, GC Corporation, Tokyo, Japan). Observation period was 28 days. After sacrificing the animals, histological preparations were done to analyze the presence of dentin bridge, inflammatory reaction of the pulp, pulp tissue reorganization and the presence of bacteria. Results Dentin bridge was observed in all teeth (experimental and control groups). Inflammation of the pulp was mild to moderate in all groups. Neoangiogenesis and many odontoblast like cells responsible for dentin bridge formation were detected. Necrosis was not observed in any case, neither the presence of Gram-positive bacteria in the pulp. Conclusion Histological analysis indicated favorable therapeutic effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite for direct pulp capping in teeth of Vietnamese pigs.

This study examined and compared wound healing between Thai propolis product and calcium hydroxide paste as pulp-capping agents after partial pulpotomy in New Zealand white rabbits. Forty incisor teeth from 10 rabbits were treated. Thirty-six teeth received class V cavity preparations with partial pulpotomy and application of either propolis or calcium hydroxide paste. Similar cavity preparations were performed in 2 teeth without any capping material as a positive control, whereas 2 teeth without the cavity preparation served as a negative control. Histological evaluation showed that both groups had dentin bridge formation. Dentinal tubules in the dentin bridge were more orderly arranged in the Thai propolis group than in the calcium hydroxide group. Wound healing and the median number of hyperemic blood vessels were not statistically significant different between the 2 groups. Thai propolis product may be used as a pulp-capping agent.

The purpose of this study was to compare the effect of a self-etching primer and a non-rinse conditioner with the effect of a conventional adhesive system on the penetration depth in dentin of human teeth, using scanning electronic microscopy (SEM). Fifteen human third molar teeth were sectioned into 2 pieces. All pieces were flattened with grade 600 to 1200 silicon carbide paper and divided into 6 groups: group 1 - Prime & Bond NT (NT), negative control; group 2 - 37% phosphoric acid + Prime & Bond NT (PANT), positive control; group 3 - Non-rinse Conditioner (NRC) + Prime & Bond NT (NRCNT); group 4 - NRC + Prime & Bond 2.1 (NRCPB); group 5 - NRC + Scotchbond MP (NRCSB); group 6 - Prompt L-Pop (PLP). All teeth were covered with Dyract AP. The tooth fragments were decalcified, and its resin replicas were evaluated by SEM by three previously standardized examiners. The penetration was scored from 0 (no penetration) to 3 (maximum penetration). The Kruskal-Wallis and Mann-Whitney U tests (p<0.05) showed three statistically homogeneous groups: {NT, NRCPB, NRCSB and PLP}, {NRCNT} and {PANT}. The authors concluded that the self-etching primer and the non-rinse conditioner provide a lower penetration depth in human tooth dentin than the conventional adhesive system.

This study was performed to examine whether calcium silicate could induce reparative dentin formation without eliciting any adverse effect in direct pulp capping of premolar teeth. Twenty participants who need extraction of their 4 healthy permanent premolar teeth for orthodontic reasons were included in this study. Following the surgical procedure, the exposed pulp tissue was treated either with calcium silicate or covered with calcium hydroxide paste. On day 3, 7, 14 and 28, the experimental teeth was extracted and examined using light microscopy and histometric analysis to observe the inflammatory changes and the amount of reparative dentin formation. The results showed that in the calcium silicate treated teeth, substantial amounts of dentine-like tissue was formed on day 14 and mostly located on the exposure site. It was also observed in the calcium hydroxide treated teeth but dentin-like tissue located at a distance from the exposure site. The total amount of reparative dentine formed in the calcium silicate-treated teeth was significantly higher (p<0.005) than in the calcium hydroxide-treated specimens. In conclusion that the calcium silicate indices pulpal wound healing and reparative formation in the exposed teeth without affecting the normal function of the remaining pulp.

Abstract Aim The purpose of this study was to compare the marginal leakage of Class II amalgam restorations whose preparations were lined with a resin-based desensitizing agent, a self-etching adhesive system, and copal varnish. Methods and Materials Fifty-six freshly extracted human premolar teeth were divided into four groups. A Class II preparation was prepared with only a proximal box on the mesial and distal surfaces of each tooth. The cavities in one group were lined with a desensitizing agent (VivaSens™) and a second group with an adhesive (Clearfil S3 Bond™). A third group was lined with copal varnish (Copalite™) and a fourth group was used as the control without any cavity liner. Spherical high copper amalgam was hand-condensed into each preparation, specimens were thermocycled, stained, and sectioned. Microleakage was graded using a stereomicroscope. Microleakage scores were calculated and analyzed using the Kruskal Wallis and the Mann-Whitney tests (α=0.05). Results Less microleakage was indicated with the VivaSens™ liner when compared with the other groups (P<0. 05). Clearfil S3 Bond™ showed less microleakage than the control group (P<0.05), but the leakage with copal varnish and Clearfil S3 Bond™ was similar (P>0.05). Conclusion VivaSens™ reduced the microleakage of Class II high copper amalgam restorations significantly more than the Clearfil S3 Bond™ and copal varnish. Citation Ghavamnasiri M, Alavi M, Alavi S.

Objective: To evaluate the clinical and radiographic outcomes (24 months) of indirect pulp treatment (IPT)in primary teeth when a self-etching primer or a calcium hydroxide layer was used over the remaining carious dentin. Study design: Primary molar teeth with deep carious lesions without signs and symptoms of irreversible pulpitis were divided into two groups, according to the capping material: Experimental group(1): self-etching adhesive system (Clearfill SE Bond); and Control group (2): calcium hydroxide liner(Dycal). Both groups were followed up after application of a resin restoration (3M - Z250). Results: After 2 years of clinical and radiographic follow-up, no statistical difference was found between groups (p=1). The overall success rate reached 87%. Conclusion: These results demonstrate that IPT has a high clinical and radiographic performance in primary teeth and is not dependent on the capping material used over the demineralized dentin.
