There is a range of diseases that make the patients go to the dental emergency service; most of them result from pulp disorders due to the painful symptoms that characterize them. The objective of this paper was to describe the behavior of pulp diseases in patients from the health area of “27 de Noviembre2dental clinic in the period of October through December To this end, a cross-sectional analytical study was conducted in adult patients aged 19 to 59 years vitalidadd diagnosed as having any of the acute pulp diseases.

Asimismo se vitapidad las lesiones por dilac El tratamiento fue realizado en un lapso de 5 meses. Respuesta Pulpar ante el recubrimiento Pulpar Directo: Full Text Available During endodontic therapy pulpectomy, root canal debridement and root canal filling microbiological management is a major concern.

Bacteria present in dentine tubules, apical foramina and apical delta are causally related to failure of the procedure. Studies have shown that during single session endodontic treatment bacteria remain within dental structures.

The aim of the present study was to evaluate endodontic treatment performed as two sessions, using temporary endodontic dressing materials for different periods in four groups of experimental dogs.

A total of 80 roots of second and third upper premolar teeth and second, third and fourth lower premolar teeth were divided into four groups. The pulp chamber was opened with burrs and the pulp exposed for 60 days to induce pulpal inflammation and necrosis. In all groups, the root canals were filled with zinc oxide-eugenol and gutta-percha cones.

Clinical and radiographical measurements were performed every 2 weeks. After 60 days a small block section containing the teeth, surrounding periapical tissues and the periodontium was removed for histological and microbiological study. Histological analysis revealed intense inflammatory response in all groups. Microbiological analysis showed microbial reduction inversely proportional to the period of time that the intracanal temporary medicament was left in place.

Insuficiencia renal aguda con necrosis tubular aguda secundaria a picadura masiva de abejas. Todo ello, hace que la capacidad defensiva del tejido pulpar sea muy limitada ante las diversas agresiones que pueda sufrir. This treatment promotes healing by reducing edema and interstitial fluid, improving microcirculation, reducing the risk of infection and promoting tissue granulation. We report the case of a 31 year old man with a large plantar defect due to distal necrosis after pneumococcal sepsis.

Pathological investigation of caries and occlusal pulpar exposure in donkey cheek teeth using computerised axial tomography with histological and ultrastructural examinations. Post-mortem examination of 16 donkey cheek teeth CT with caries both peripheral and infundibular and pulpar exposure were performed using computerised axial tomography Uplparhistology and scanning electron microscopy.

CAT imaging was found to be useful to assess the presence and extent of caries and pulp exposure in individual donkey CT. Histology identified the loss of occlusal secondary dentine, and showed pulp necrosis in teeth with donservacion exposure.

Viable pulp was present more apically in one exposed pulp horn, with its occlusal aspect sealed off from the exposed aspect of the pulp horn by a false pulp stone. Scanning electron microscopy showed the amelo-cemental junction to be a possible route of l infection in infundibular cemental caries.

The basic pathogenesis of dental caries in donkeys appears very similar to its description in other species. Full Text Available Objetivo: Reporte de Dos Casos. Ellas pueden conseervacion posibilitando el reemplazo de tejidos afectados aunque sean de otros linajes celulares.


Pain is a symptom very important in the stomatologic practice and particularly in that concerning to dental pulp alterations.

To deep in the knowledge of phases crossed by a pulpal inflammatory process allowing predicting its painful manifestations, authors made a bibliographic review on this subject with a multidisciplinary and basic-clinical approach, using the documentary method for analysis and management of information offered by theoretical sources. The classification of pulpal inflammation state, taking into account non. Avascular osteonecrosis AON has increased in the last few years in patients infected with the human immunodeficiency virus type-1 HIV The most commonly affected bone is the femoral head and neck.

Frequently these bilateral and clinical findings include moderate to severe pain and functional impotence of the affected joints. The etiology is multifactorial and highly active antiretroviral therapy HAART with protease inhibitors PI is probably related to its development.

In the evolution, a total hip replacement may be needed. The principal indications of MTA are vital pulp therapy pulpotomy, direct pulp capping, apexification apical plug, endodontic surgery, and lateral, furcal and resorption perforations repair. The MTA induce the formation of cementum and bone, and it may facilitate the regeneration of the periodontal ligament without causing any inflammation; as a helping of the. Is tumor necrosis factor – a promoter polymorphism associated with susceptibility to multiple sclerosis?

Thus, no significant differences in genotype and allele frequencies were found between healthy individuals and patients with MS in Argentina.

Pulpar temperature changes during mechanical reduction of equine cheek teeth: Although equine motorised dental instruments are widely used, there is limited information on their thermal effect on teeth.

The recently described variation in subocclusal secondary dentine depth overlying individual pulp horns may affect heat transmission to the underlying pulps.

This study laa the effect of 3 different equine motorised dental instruments on the pulpar temperature of equine cheek teeth with and without the use of conservscion cooling. It also evaluated the effect of subocclusal secondary dentine thickness on pulpar temperature changes.

A thermocouple probe was inserted into the pulp horns of transversely sectioned maxillary cheek teeth with its tip lying subocclusally. Pulpar temperature changes were recorded during and following the continuous use of 3 different equine motorised dental instruments A, B and C for sequential time periods, with and without the use of water cooling. Using motorised dental instrument B compared with either A or C increased the likelihood that the critical temperature was reached in pulps by 8.

Prolonged rasping with motorised dental instruments increased the likelihood that a pulp would be heated above the critical temperature. Increased dentinal thickness and water cooling had protective roles in reducing pulpar heating. Motorised dental instruments have the potential to seriously damage equine pulp if used inappropriately.

Higher speed motorised dental instruments should be used for less time and teeth should be water cooled during or immediately after instrument use to reduce the risk of thermal pulpar damage. Full Text Available This study evaluated the biocompatibility of mineral trioxide aggregate MTA after direct capping of exposed pulp tissue conservacuon dog’s teeth. Class I cavities were prepared in 26 teeth from 3 adult dogs. MTA was applied over the exposed pulp in 13 teeth and paste of calcium hydroxide plus distilled water ocnservacion was applied in the remaining 13 teeth.

After 90 days, fe animals were killed; the maxilla and mandible were dissected and sectioned to obtain individual roots. The samples were processed histologically. The pulp and periapical response observed with the use of MTA was similar to that of calcium hydroxide paste.


In all specimens, there was a dentin bridge obliterating the exposure, an intact odontoblastic layer, no inflammatory cells, normal connective pulp tissue, normal apical and periapical regions and no bone tissue changes. Similar to calcium hydroxide, MTA vitxlidad excellent response when used for direct pulp capping. A resposta dos demais foi positiva ao teste.


Targeting of regulated necrosis in kidney disease. Pulp capping is an important measure and one with a high rate of use in daily dental practice, and when it is conscientiously performed, based on good diagnosis of lla pulp condition at the time of vitalisad exposure, it may prevent the tooth from requiring endodontic intervention.

In addition to calcium hydroxide, other materials have been tested with regard to their action in promoting pulp repair by the formation of a dentin bridge after direct pulp capping. These materials do not promote formation of a necrotic area, characteristic of the use of calcium hydroxide, are biocompatible and favor pulp tissue repair.

To evaluate the effects of these materials on pulp capping, this literature review was conducted, the approach being wide ranging in scope, from pulp response. Study in vitro of dental oa irradiated with a high power diode laser operating at nm: This study examines the structural and thermal modifications cnoservacion in dental enamel under dye assisted diode laser irradiation. The aim of this study is to verify if this laser-assisted treatment is capable to modify the enamel surface by causing fusion of the enamel surface layer.

At the same time, the pulpal temperature rise must be kept oulpar enough in order not to cause pulpar necrosis. To achieve this target, it is necessary to determine suitable laser parameters.

As is known, fusion of the enamel surface followed by re-solidification produce a more acid resistant layer. This surface treatment is being researched as a new method for caries prevention. A series of fourteen identically prepared enamel samples of human teeth were puulpar with a high power diode laser operating at nm and using fiber delivery.

Prior to irradiation, a fine layer of cromophorous ink was applied to the enamel surface. In the first part of the experiment the best parameter for pulse duration was determined.

In the second part of the experimental phase the same energy density was used but with different repetition rates. During irradiation we monitored the temperature rise in the pulpal cavity. The morphology of the treated samples was analysed under SEM.

The morphology of the treated samples showed a homogeneously re-solidified enamel layer. The results of the temperature analysis showed a pa of the pulpal temperature rise with decreasing repetition rate.

With the diode laser it is possible to cause morphological alterations of the enamel surface, which is known to increase the enamel resistance against acid attack, and still maintain the temperature rise in the pulpar chamber below damage threshold.

La muestra de este estudio estaba formada puppar 60 ratas de raza Sprague-Dawley. Ischemic necrosis and osteochondritis.

Osteonecrosis indicates that ischemic death of the cellular constituents of bone and marrow has occurred. Historically, this first was thought to be related to sepsis in the osseous segments. However, continued studies led to the use of the term aseptic necrosis. Subsequent observations indicated that the necrotic areas of bone were not only aseptic, but were also avascular.

This led to the terms ischemic necrosisvascular necrosis and bone infarction. Ischemic necrosis of bone is discussed in this chapter. It results from a significant reduction in or obliteration of blood supply to the affected area. The various bone cells, including osteocytes, osteoclasts, and osteoblasts, usually undergo anoxic death in 12 to 48 hours after blood supply is cut off.
