Abstract:
This case report illustrates the teeth morphology of a chimpanzee and its anatomical variations. A well-preserved skull of a male Pan troglodytes troglodyte chimpanzee was scanned using a cone-beam computed tomography machine. Measurements included tooth and crown height, root length, root canal length and width (posterior teeth), and pulp cavity length (anterior teeth). Nonmetrical parameters included number of canals and foramina per root of every root. Interestingly, the mandibular central incisor was longer than the lateral incisor, and all the mandibular anterior teeth presented with a solitary flame-shaped or conical-calcified structure in their pulp cavity. The premolars are usually dual rooted except for the first maxillary premolar that displayed 3 roots. Other unusual discoveries were the presence of bilateral radicular dens invaginatus in the mandibular first premolars and the possibility of having 2 canals and 2 foramina in the roots of the posterior teeth. The presence of conical stone mineralizations at the pulp cavity and the presence of dens invaginatus were of particular interest.

Abstract:
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.

Abstract:
During odontogenesis, amelogenins from the preameloblasts are translocated to differentiating odontoblasts in the dental papilla, suggesting that amelogenins may be associated with odontoblast changes during development. In the present study, we have explored the effects of enamel matrix derivative (EMD) on the healing of a pulpal wound. Coronal pulp tissue of permanent maxillary premolars of miniature swine were exposed through buccal class V cavities. The exposed pulp was capped with EMD. The contralateral teeth served as controls and were capped with a calcium hydroxide paste (Dycal®). The cavities were sealed with glass-ionomer cement. After 2 and 4 weeks, the histology of the teeth was analyzed. In the EMD-treated teeth, large amounts of newly formed dentin-like hard tissue with associated formative cells outlined the pulpal wound separating the cavity area from the remaining pulp tissue. Inflammatory cells were present in the wound area but not subjacent to the newly formed hard tissue. Morphometric analysis showed that the amount of hard tissue formed in EMD-treated teeth was more than twice that of the calcium-hydroxide-treated control teeth (p < 0.001), suggesting that EMD is capable of promoting reparative processes in the wounded pulp more strongly than is calcium hydroxide.

Abstract:
This study evaluated the short-term response of human pulp tissue when directly capped with Portland cement. In this series of cases, twenty human third molars that were scheduled for extraction were used. After cavity preparation, pulp exposure was achieved and Portland cement pulp capping was performed. Teeth were extracted after 1, 7, 14 and 21 days following treatment and prepared for histological examination and bacterial detection. Each group had 5 teeth. The results were descriptively analysed. Dentin bridge formation was seen in two teeth with some distance from the material interface (14 and 21 days). Soft inflammatory responses were observed in most of the cases. Bacteria were not disclosed in any specimen. PC exhibited some features of biocompatibility and capability of inducing mineral pulp response in short-term evaluation. The results suggested that PC has a potential to be used as a less expensive pulp capping material in comparison to other pulp capping materials.

Abstract:
AbstractEvaluation of secondary dentin formation is generally suitable for age assessment. We investigated the potential of modern magnetic resonance imaging (MRI) technology to visualize the dental pulp in direct comparison with cone beam computed tomography (CBCT). To this end, we examined 32 extracted human teeth (teeth 11–48 [FDI]) using 9.4-T ultrashort echo time (UTE)-MRI and CBCT (methods). 3D reconstruction was performed via both manual and semi-automatic segmentation (settings) for both methods in two runs by one examiner. Nine teeth were also examined by a second examiner. We evaluated the agreement between examiners, scan methods, and settings. CBCT was able to determine the pulp volume for all teeth. This was not possible for two teeth on MRI due to MRI artifacts. The mean pulp volume estimated by CBCT was consistently higher (~ 43%) with greater variability. With lower variability in its measurements, evaluation of pulp volume using the MRI method exhibited greater sensitivity to differences between settings (p = 0.016) and between examiners (p = 0.009). The interactions of single-rooted teeth and multi-rooted teeth and method or setting were not found to be significant. For examiner agreement, the mean pulp volumes were similar with overlapping measurements (ICC > 0.995). Suitable for use in age assessment is 9.4-T UTE-MRI with good reliability and lower variation than CBCT. For MRI, manual segmentation is necessary due to a more detailed representation of the interior of the pulp cavity. Since determination of pulp volume is expected to be systematically larger using CBCT, method-specific reference values are indispensable for practical age assessment procedures. The results should be verified under in vivo conditions in the future.

Abstract:
Introduction. Trauma injury in the oral cavity due to collisions can cause tooth fracture. Ellis class III fracture is a fracture of the crown with an open pulp. Teeth with exposed pulp will cause irritation of the pulp resulting in pulp inflammation (pulpitis). One visit pulpectomy and jacket crown with posts were carried out to achieve optimal dental functions. Case report. A 27-year-old male patient came to Dental Hospital of Universitas Gadjah Mada complained about his broken front teeth due to accident three days earlier. The crown of the maxillary right lateral incisor and the maxillary left central incisor with open pulp was seen. The tooth 11 was avulsion, which lost at the location of accident. The diagnosis of 12 and 21 were Ellis class III fracture. Initially an infiltration anaesthesia was done, followed by one visit root canal treatment (RCT). On the second visit, the teeth were asymptomatic, hence the jacket crown preparation and fiber post insertion were performed. On the third visit, a porcelain jacket crown was cemented into teeth 12 and 21. A week later the patient came for recall and no complaints were noted. Conclusion. One visit pulpectomy followed by restoration with porcelain crown and fiber posts can be undertaken to achieve the optimal functions of teeth, namely aesthetic, mastication, phonetics, and protection of supporting tissues function.

Abstract:
SUMMARY Objectives It has been suggested that laser preconditioning can produce dental anaesthesia. This study aimed to assess the response of the dental pulp to laser preconditioning. Methods The effects of laser preconditioning, sham laser (negative control), and composite curing light (positive control) on the response of the dental pulp to electric pulp testing was investigated in this double-blind crossover trial with six volunteers. The Er,Cr:YSGG laser or curing light was shone on a premolar tooth in a sweeping motion for 30 seconds (in the sham treatment, the laser was not activated) in blindfolded volunteers subjected to a consistent aural stimulus. Treatment method at each visit was randomized and performed by a researcher not involved in pulp testing. Teeth were pulp tested twice initially by another member of the research team to get baseline readings, immediately following the treatment, and thereafter every two minutes for 10 minutes. Results were analyzed using analysis of variance and an independent-sample t-test. Results There were no significant differences in pulpal response between treatments (p>0.05). Conclusion Laser preconditioning did not affect pulpal response as measured by an electronic pulp tester. Laser preconditioning did not result in any pain or noticeable symptoms for both teeth and soft tissues.

Abstract:
Abstract Dental methods are an important element of forensic age assessment of living persons. After the development of all the teeth, including third molars, is completed, degenerative characteristics can be used to assess age. The radiologically detectable reduction of the dental pulp cavity has been described as such a feature. We investigated the suitability of ultrahigh field 9.4 T ultrashort time echo (UTE) magnetic resonance imaging (MRI) for the evaluation of pulp cavity volume in relation to the total tooth volume in 4 extracted human teeth. The volume calculations were performed after semi-automatic segmentation by software AMIRA using the different intensities of the structures in the MRI dataset. The automatically selected intensity range was adjusted manually to the structures. The visual distinction of pulp and tooth structure was possible in all cases with in-plane resolution < 70 μm. Ratios of tooth/pulp volume were calculated, which could be suitable for age estimation procedures. Intensity shifts within the pulp were not always correctly assigned by the software in the course of segmentation. 9.4 T UTE-MRI technology is a forward-looking, radiation-free procedure that allows the volume of the dental pulp to be determined at high spatial resolution and is thus potentially a valuable instrument for the age assessment of living persons.

Abstract:
The subject. Significant preparation of the teeth for metal-ceramic or ceramic crowns in most cases is accompanied by a preliminary devitalization of the teeth, which shortens the period of their survival.
 The problem of ensuring the vitality of supporting teeth can be solved by amputating only the coronal pulp, which inevitably overheats during preparation, while retaining the root pulp.
 The skeptical attitude of dentists to vital pulpotomy may be explained by the often unsuccessful (ineffective) use of this method for teeth with already affected pulp. The hope for success in this study is based on the choice of intact teeth for vital pulpotomy of subsequent prosthetics.
 Urgency. The amputation method of endodontic dentistry is not used for prosthetic purposes. This can be explained by its low efficiency when using teeth with inflamed pulp.
 The aim of the work is to confirm the effectiveness of vital pulpotomy in a typical dental situation and subsequent prosthetics.
 Methodology. Clinical observation of the patient before and during 1 year after treatment, with the use of clinical and modern paraclinical methods of examination. Diagnosed. Treatment is planned: removable denture on the upper jaw with a preliminary shortening of the tooth 46 and subsequent use of a metal-ceramic crown. Significant sosotoyanie hard tissues of the tooth 46 and the subsequent preparation for artificial crowns required endodontic-specific training. It was supposed to preserve the root pulp (vital pulpotomy).
 As a result, there were no complaints at the control examination 1 year after pulpotomy. The pain threshold from the electrode was 11 µa.
 Summary. The vital pulpotomy of the tooth with intact pulp showed the possibility of its effective prosthetics with an artificial crown while maintaining the viability of the root pulp. The technique of introduction of the electrode into the cavity of the tooth allowed to conduct direct measurements of the pain threshold of the root pulp in the dynamics of (application for invention No. 2017115518/17(026915) from 02.05.2017).

Abstract:
Testing the vitality of teeth using electric pulp testers was reviewed. Two studies then investigated aspects of the application of electric pulp testing (EPT) to healthy first molar teeth. Twenty volunteers with first molars free of restorations and caries were recruited. One molar from each arch was selected and rubber dam applied. The tester probe was coated with fluoride gel. Seven sites on each crown were EPT tested four times, and all threshold responses recorded. Data were analysed using one way ANOVA at the 0.01 level. The lowest response for both the maxillary and mandibular teeth was with the probe on the mesio-buccal cusp tip. Males responded at a lower level than females at the mesio-buccal cusp tip, but this did not reach statistical significance. The relationship between pulp areas and dimensions on radiographs and the EPT results was investigated. Standardised bitewing radiographs of the tested molars were mounted and digitally scanned. Five measurements were taken using a computer program; crown width, the mesial and distal pulp horn heights, the area of the clinical crown, and the pulp area in the clinical crown. The four electrode placement sites with the lowest threshold from the pulp testing results were selected. Pearson correlations (2-tailed) were used to relate the measurements. There were no correlations between the coronal pulp size, pulp horn height and the probe placement site. The exception was an anomalous correlation between the distal horn height and mesio-buccal cuspal area of the maxillary molars.

Abstract:
This study investigated some characteristics of dental pulp stromal/stem cells (DPSCs) isolated from healthy teeth (hDPSCs) compared to DPSCs isolated from teeth with shallow carious lesions (cDPSCs) with a view to the use of both cell types in hard tissue engineering strategies. Osteogenic differentiation was investigated using appropriate histochemical staining and osteogenic marker expression (ALPL, OC, RUNX-2). In addition, angiogenic (VEGFR-2, PECAM-1) and inflammatory gene markers (TLR-2, TLR-4) were investigated together with the secretion of the pro-inflammatory cytokines (IL-6 and IL-8). The activity of the pro-osteogenic IGF axis was also investigated in hDPSCs and cDPSC cultures. cDPSCs exhibited significantly higher clonogenic potential, and possess a higher proportion of cell that express mesenchymal stem cell markers (CD146+, CD90+ and CD105+, CD45-, CD31-) compared with hDPSCs. Evidence also suggested that cDPSCs had a greater osteoblastic differentiation potential than hDPSCs. cDPSCs expressed higher levels of inflammatory markers than hDPSCs together with higher concentrations of IL-6 and IL-8 in conditioned medium indicative of retention of a carious phenotype following cell isolation and culture. Finally functional examination of the IGF axis suggested a role for insulin-like growth factor binding proteins-2 and -3 (IGFBP-2 and -3) in the osteogenic differentiation of DPSCs. Therefore cDPSCs are comparable to hDPSCs in terms of their osteogenic potential and the inflammatory environment of cDPSCs may offer a promising cell source for future mineralised tissue repair and regeneration.

Full text
Abstract:
Abstract The dentin-pulp complex comprises mineralized dentin and the vital soft tissues encased inside dentin, i.e. odontoblasts and pulp tissue. During caries progression, the dentinal minerals are dissolved and eventually the collagenous organic matrix is degraded. However, the exact mechanisms and enzymes responsible for the organic matrix breakdown remain unknown. Matrix metalloproteinases (MMPs), a family of endopeptidases capable of degrading in concert virtually all extracellular matrix components, are expressed during normal dentin-pulp complex formation and maintenance. MMP activity has also been suggested to contribute to the organic matrix degradation during dentin caries progression and to the repair and defense reactions elicited by caries in the dentin-pulp complex cells. The aim of the study was to further elucidate the role of host MMPs in dentin caries progression and the origin of MMPs in carious dentin as well as the possible changes in MMP expression in the cells of the dentin-pulp complex in response to caries. MMP inhibitors decreased the area of dentin caries lesions in vivo, suggesting the involvement of host MMPs in dentin caries pathogenesis. When the overall MMP gene expression was examined by cDNA microarray, pooled pulp samples demonstrated a high level of MMP-13 expression, but failed to show any unequivocal changes in MMP expression due to caries. MMP-13 expression is rare among normal human adult tissues. Real-time quantitative PCR of individual pulp and odontoblast samples demonstrated a rather large variation in relative MMP-13 mRNA expression between samples, especially pulp samples. Protein expression of MMP-13 was detected in pulp and odontoblasts without any major differences between the tissues of sound and carious teeth. This was also the case with the MMP-20 (enamelysin) protein, which was demonstrated in odontoblasts and the pulp tissue of fully developed human teeth. MMP-20, MMP-8, and gelatinases (especially MMP-2) were demonstrated in human dentin, and dentinal MMPs exhibited activity against native and denatured type I collagen when released. The study demonstrates the presence of MMPs in the soft and hard tissue compartments of the dentin-pulp complex. These enzymes may also contribute to dentin caries progression and response reactions to caries.

Abstract:
AbstractImmediately after the Great Hanshin-Awaji Earthquake in 1995 and the Great East Japan Earthquake in 2011, pneumonia outbreak among the elderly increased the rate of fatalities. What caused this? To use lessons learned during the large-scale disaster, specialists concerned with the field of dentistry began to take action using new perspectives. Consequently, they noticed the importance of giving care to the entire oral cavity as well as the teeth. Based on reports from a dentist and a dental hygienist who tackled the oral care of the Kumamoto Earthquake victims in 2016, their methods of effective health care following a disaster is presented in this paper. We also propose a preventative medical activity that can be conducted sustainably for anyone, not just medical personnel.

Abstract:
The radiographs most frequently taken in general dental practice are of the teeth and their immidiate supporting tissues for detection of dental caries or assessment of bone loss in periodontal disease. Intraoral radiographs are taken by placing the X-ray-sensitive film or receptor in the mouth close to the teeth being investigated. Extraoral radiographs use larger films or receptors positioned externally and produce a view of the entire dentition and its supporting structures on a single film; they are used to ascertain the state of development of the dentitions prior to orthodontic treatment, for example. Dental panoramic tomographs (DPTs) are the most frequent extraoral radiographs. A radiograph is a negative photographic record. Dense structures such as bone are designated as radio-opaque; they absorb some X-rays and appear white on radiographs. More X-rays pass through less dense radiolucent structures such as air-filled cavities which show up as black areas. The contrast between different tissues of the structures which the X-ray beam passes through is determined by their radiodensity which, in turn, is largely due to their content of metallic elements. Calcium and iron are the prevalent heavy metals in the body. Calcium is combined with phosphate to form hydroxyapatite crystals in bones and mineralized tissues in teeth. Iron is present in haemoglobin in blood, but only large concentrations of blood, such as those found within the heart chambers, show up on X-rays. In sequence from densest to most lucent, the radiodensity of the dental and periodontal tissues are: enamel, dentine, cementum, compact bone, cancellous bone, demineralized carious enamel and dentine, dental soft tissues such as pulp and periodontal ligament, and air; gold and silver–mercury amalgam metallic restorative materials are even denser than enamel. A radiograph is a two-dimensional representation of a three-dimensional situation. The orientation of anatomical structures relative to the X-ray beam is a major factor determining their appearance on the film. For example, a beam travelling through the long axis of a radiodense structure will produce a whiter image on the film than one passing through its shorter axis because more X-rays are absorbed; the structure will also have a different shape.

Abstract:
Dental anesthesia is indicated for most procedures of the oral cavity. Soft tissue (mucosal tissues such as the buccal mucosa and gingiva), teeth, and the pulp tissue (composed of nerve fibers, vasculature, lymphatics, and connective tissue inside of the tooth), and supporting structures of the tooth (bone and periodontal ligament) are all necessary structures to be anesthetized. Choice of tissue to be anesthetized depends on the goal of the procedure. Restorative procedures (amalgam and composite restorations, inlays, onlays), prosthetic procedures (crowns and veneers), endodontic procedures (root canals, apicoectomy or root-end surgery, pain diagnosis), periodontal procedures (scaling and root planing, crown lengthening, sinus lift, connective tissue grafting, guided bone regeneration, gingivectomy), and oral surgery procedures (extractions, implant placement, incision and drainage, and biopsy) all will require anesthesia to reduce patient pain and anxiety.

Abstract:
Fracture of restored teeth is a problem in restorative dentistry since it has been estimated that 92 percent of fractured teeth have been previously restored. In a restored tooth, the stresses that occur at the tooth-restoration interface during loading could become large enough to fracture the tooth and/or restoration. The tooth preparation process for a dental restoration is therefore a classical optimization problem: tooth reduction must be minimized to preserve tooth tissue whilst stress levels must be kept low to avoid fracture of the restored tooth. The objective of the present study was to propose alternative optimized designs for a second upper premolar cavity preparation by means of structural shape optimization based on the finite element method and biological adaptive growth. Restored tooth models using the optimized cavity shapes exhibited significant reduction of stresses along the tooth-restoration interface. In the best case, the maximum stress value was reduced by more than 50 percent.

Abstract:
A new heat sink has been designed that increases the run time of a cavity-filling resin-curing or teeth-bleaching dental device with light emitting diode. The heat sink is a hollowed copper object that is filled with a phase change material. Computational simulations and experimental measurements are presented that show the heat sink with phase change material increases the run time of the device beyond the minimum requirement of six minutes.

Abstract:
Haptics is one of the most important sensations for dentists to prepare cavity in dental surgery, which is however not easy to simulate in a computer system because of the large drilling force and the small speed of movement and material removal. In this paper, we present a fully voxel-based approach to interactively simulate dental drilling. Different from those voxel/mesh hybrid models, the drilling forces are computed directly from the voxel-representation while considering the factors of teeth’s material properties, the posture and forward speed of dentist’s drill and the contact surface area. To overcome force discontinuity caused by removal of tooth material, we define two layers of voxels on drill, where the boundary voxels are only employed to compute force feedback and the interior voxels are adopted to remove materials from teeth. The experimental result shows that our force model can produce smooth and large force feedback at a slow movement on haptic devices. Other than haptic rendering, a real-time filtering method directly using voxel representation has also been developed to improve visual rendering in dental simulation.
