ABSTRACT Objective: The aim of this study was to investigate the effect of cavity design and the type of pulp capping materials on the fracture resistance of Class II composite restorations. Materials and Methods: Sixty freshly extracted, sound molar teeth were selected for the study. A dovetail cavity on the mesio-occlusal and a slot cavity on disto-occlusal surfaces of each tooth were prepared, and the teeth were divided 4 groups which one of them as a control group. The pulp capping materials (TheraCal LC, Calcimol LC, Dycal) applied on pulpo-axial wall of each cavity, and the restoration w

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

To determine the in vivo effects of a zinc oxide-eugenol mixture (ZOE) on the cyclo-oxygenase system in dental pulp, we used radioimmunoassay to measure the levels of prostaglandin E2 (PGE2), 13,14-dihydro-15-keto-PG (DHK-PG), thromboxane B2 (TXB2), and 6-keto-PGF1α in the dental pulp of rats. When the dental pulp was irritated by a hole made in the dentin of the mandibular incisors without use of any coolants, the levels of these cyclo-oxygenase products in the pulp were increased to, respectively, 2.8, 1.7, 10.0, and 2.6 times those in the normal pulp at six hr after treatment.

In order to determine the age of adult wild dogs, we compared two methods (that of Thomson and Rose (TR method) and that of Knowlton and Whittemore (KW method)) of measuring and calculating pulp cavity : tooth width ratios on upper and lower canine teeth from 68 mixed-sex, known-age wild dogs of 9 months to 13 years of age reared at two localities. Although significant relationships (P = 0.0001) were found between age and pulp cavity ratios by both methods, the TR ratio calculation and measurement showed heteroscedasity in error variance whereas the KW ratios had a more stable error variance a

Resumen

Indirect pulp treatment is a conservative vital pulp procedure performed in deep carious lesion approximating the pulp, but without signs or symptoms of pulp degeneration. Removing the carious biomass along with sealing the residual caries from extrinsic substrate and oral bacteria makes residual caries after the first excavation less active. This allows time for pulpo dentinal complex to form tertiary dentine so that at the second excavation, there is less likelihood of pulpal exposure. It has also been suggested that by changing the cavity environment from an active lesion into a more slowly

Abstract Diagnosis can be defined as the art of distinguishing one disease from another. One of the most essential part of the diagnostic procedure for pulp disease is the use of pulp sensibility tests. When diagnosing pulp pain, these tests can be used to reproduce the symptoms reported by the patient to diagnose the diseased tooth as well as the disease state. There are several pulp sensibility tests available such as thermal tests (heat and cold stimuli), electric pulp tests (EPT), and a test cavity. But which test should be used in which condition still remains a confusion for the dentist.

The complete eradication of bacteria in a caries-affected tooth, during cavity preparation, is considered a difficult clinical task. In addition to weakening the tooth structure, attempts to excavate extensive carious tissue completely, by only mechanical procedures, may affect the vitality of the pulp.

However, their capacity to contribute efficiently to reparative dentin formation after pulp lesion has never been explored. After pulp exposure, we have identified proliferative cells within 3 zones. In the crown, zone I is near the cavity, and zone II corresponds to the isthmus between the mesial and central pulp. In the root, zone III, near the apex, at a distance from the inflammatory site, contains mi

Resumen

The feral mink population in Denmark consists of two groups of animals: mink born in the wild and mink that have recently escaped from farms. The aims of this study were to: (1) estimate the reproductive performance and mortality of the Danish mink born in the wild (wild-born) and mink escaped from farms (captive-born); (2) discuss the likelihood of a self-sustaining population of wild-born mink in Denmark; and (3) model the relationship between the pulp cavity width and the age of mink. During 2018, 247 wild caught mink were sent for necropsy at the Danish National Veterinary Institute. Based

Resumen

An 8-year-old, 125 kg (275 lb) female miniature horse was evaluated for a persistently thickened left mandible and cutaneous fistula. Pulp horn defects were identified in pulp horns 1 and 3 of tooth 309 and occlusal pulp exposure was detected with a dental explorer. Radiography of the left mandibular dental quadrant revealed changes consistent with apical infection of tooth 309. Following the failure of oral extraction, a standing surgical approach was taken for transcutaneous lateral alveolar ostectomy and extraction. Roots were sectioned at the level of the furcation and elevated from the su

Resumen

The oral cavity may serve as a reservoir of Helicobacter pylori. However, the factors required for H. pylori colonization are unknown. Here, we analyzed the relationship between the presence of H. pylori in the oral cavity and that of major periodontopathic bacterial species. Nested PCR was performed to detect H. pylori and these bacterial species in specimens of saliva, dental plaque, and dental pulp of 39 subjects. H. pylori was detected in seven dental plaque samples (17.9%), two saliva specimens (5.1%), and one dental pulp (2.6%) specimen. The periodontal pockets around the teeth, from whi

Resumen

The most common method of evaluating pulp tissue reactions to injury is by a qualitative assessment of pulp tissue alterations. This evaluation method is subjective and difficult to quantify; stereological methods are more suitable, for they can quantify important tissue components, and so more objectively describe pulp tissues. This study compares a morphometric and a descriptive method of classification for pulp tissue analysis by using 15 teeth with inflamed pulp tissue, and 12 teeth experimentally pulp-capped with calcium hydroxide. Morphometric analysis allowed for volumes of remaining de

Resumen

Since the 1950s, clinicians have relied on various formulations of Ca(OH)2 to stimulate dentin bridge formation. Various studies (Kozlov and Massler, 1966; Massler, 1967; Brannstrom, 1978; Cox et al., 1987; Snuggs et al., 1993) have demonstrated that pulp healing and dentin bridging can occur against a pH spectrum of materials. Recent studies (Akimoto et al., 1998; Cox et al., 1998, 1999; Tarim et al., 1998; Kitasako et al., 1999; Hafez et al., 2000) have reported successful pulp healing and dentin bridging using adhesives for direct capping of exposed pulps.

Resumen

Treatment options of pulp exposure involve either extraction or root canal therapy, as latter involves multiple appointments and considerable expense. An alternate procedure is pulp capping, which is divided into two types- direct, indirect pulp capping. The aim of this study was to assess and compare the success rate of direct and indirect pulp capping procedures based on postoperative pain and patient's visit after pulp capping procedure. As it was a retrospective analysis, data collected from hospital, Chennai, and it consisted of a total of 439 cases evaluated based on the type of pulp cap
