Resumen

Objectives The aim of this study was extracting any single tooth from a CBCT scan and performing tooth and pulp cavity segmentation to visualize and to have knowledge of internal anatomy relationships before undertaking endodontic therapy. Methods: We propose a two-phase deep learning solution for accurate tooth and pulp cavity segmentation. First, the single tooth bounding box is extracted automatically for both single-rooted tooth (ST) and multirooted tooth (MT). It is achieved by using the Region Proposal Network (RPN) with Feature Pyramid Network (FPN) method from the perspective of panora

Resumen

Pulp debridement and disinfection in the pulp cavity is a critical step in achieving a successful root canal therapy. Microorganisms remaining in the root canal system after endodontic treatment are a main cause of root canal failure. The challenges faced in endodontic disinfection include the complex anatomy of the root canal system, the existence of a biofilm within the root canal, and the creation of a problematic smear layer during instrumentation of the canal. Historically, sodium hypochlorite and ethylenediaminetetraacetic acid have been utilized as irrigants and still remain as the most

Resumen

The macroscopic and microscopic anatomy of the oral cavity is complex and unique in the human body. Soft-tissue structures are in close interaction with mineralized bone, but also dentine, cementum and enamel of our teeth. These are exposed to intense mechanical and chemical stress as well as to dense microbiologic colonization. Teeth are susceptible to damage, most commonly to caries, where microorganisms from the oral cavity degrade the mineralized tissues of enamel and dentine and invade the soft connective tissue at the core, the dental pulp. However, the pulp is well-equipped to sense and

ABSTRACT Aim To describe the management of type II dens invaginatus in permanent maxillary lateral incisors. Background Teeth affected by dens invaginatus show a deep infolding of enamel and dentine starting from the foramen coecum or even the tip of the cusps which may extend deep into the root. Dens invaginatus can be managed conservatively when it does not involve pulp and periodontal ligament. Moreover it may show a broad spectrum of morphologic variations and frequently results in early pulp necrosis if left undetected in early stages.

Three monoclonal antibodies, designated RM-1, TRPM-1, and TRPM-2, were raised against rat peritoneal macrophages. By the immunoperoxidase method, antigens recognized by these antibodies were distributed throughout most tissue and free macrophages examined, including those of splenic red pulp, lymphatic sinus, connective tissue, and peritoneal cavity, as well as Kupffer cells of liver and alveolar macrophages. The numbers of positive cells were different for each antibody. RM-1 and TRPM-1 were also reactive with interdigitating cells (IDCs) in the thymus-dependent area and with Langerhans cells

Background and aims. Visualization of the internal and external root canal morphology is very important for a successful endodontic treatment; however, it seems to be difficult considering the small size of the tooth and the complexity of the root canal system. Film-based or digital conventional radiographic techniques as well as cone beam computed tomography provide limited information on the dental pulp anatomy or have harmful effects. A new non-invasive diagnosis tool is magnetic resonance imaging, due to its ability of imaging both hard and soft tissues. The aim of this study was to demons

Resumen

The common evolutionary history humans share with mammals provides us with a solid basis for understanding normal oropharyngeal anatomy and functions. Physiologically, feeding is a cycle of neurophysiologic activity, where sensory input travels to the CNS which sends motor signals out to the periphery. Research with animal models is valuable because it is possible to disrupt this cycle, and develop predictive models on the causal basis of deviation from normal. Based on work with animal models, normal mammalian infant feeding behavior consists of the tongue functioning as a pump. First, the to

SUMMARY Objectives The aim of this study was to evaluate the penetration level of potassium nitrate–containing desensitizers or whitening materials into the pulp cavity with regard to the concentration and viscosity of the formulation. Methods and Materials Fifty extracted human molar teeth were prepared and randomized into five groups of 10 specimens each. The control received a 30-minute treatment without any treatment material; the other four groups corresponded to treatment with DayWhite, a 14% hydrogen peroxide whitening material containing potassium nitrate; PreviDent 5000 Sensitive, a d

Resumen

Aim. To study the morphological changes in the tooth pulp of experimental animals when modelling acute partial pulpitis using calcium silicate modified with light-cured resin and calcium hydroxide.Materials and methods. An experimental model of acute partial pulpitis was applied including the formation of a cavity on the lingual surface of the tooth, which corresponded to advanced caries in terms of depth, followed by a slight perforation up to the tooth pulp with a sharp probe. This model of acute partial pulpitis was reproduced for 32 teeth in four sexually mature rams. The teeth were extrac

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) i

The aim of the study was to analyze and quantify the influence of isthmus extension and depth of MOD cavity of upper premolars on stress distribution by means of two-dimensional finite element method. Seven different homogeneous and elastic models were created:Model 1, intact teeth;Model 2, MOD cavity with 2 mm isthmus, 2 mm depth and composite resin restoration;Model 3, MOD cavity with 2 mm isthmus, 3 mm depth and composite resin restoration;Model 4, MOD cavity with 2 mm isthmus, 4 mm depth and composite resin restoration;Model 5, MOD cavity with 4 mm isthmus, 2 mm depth and composite resin r

Resumen

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 so

Resumen

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 afte

Resumen

Introduction: Age estimation has an important role in the process of human identification and needs to be performed in an efficient, fast, and accurate ways. Age estimation based on the pulp cavity volume of canines was referring to the theory stated that the apposition of secondary dentine during human life could be determined as an age indicator. This study was aimed to estimate the human age based on the pulp volume of canines for chronological estimation. Methods: Forty-one canine teeth from Cone Beam Computed Tomography (CBCT) 3D image sample from Dental Hospital of the Faculty of Dentist
