OBJECTIVES To quantify the temperature increments in a simulated dental pulp following irradiation with an Er:YAG laser, and to compare those increments when the laser is applied with and without water spray. METHODS Two cavities were prepared on either the buccal or lingual aspect of sound extracted teeth using the laser. One cavity was prepared with water spray, the other without and the or...

The recurrent spontaneous formation of abscesses affecting multiple noncarious primary as well as permanent teeth is the principle clinical dental feature in cases of hypophosphatemia, a condition inherited through the X chromosome. Patients often have high pulp horns, large pulp chambers and dentinal clefts. We report a case of hypophosphatemic vitamin D-resistant rickets in a patient who repo...

BACKGROUND Dental age of adults can be estimated by the analysis of the progressive physiological and degenerative phenomena which affect dental tissues. The pulp-dentinal complex is one of the dental structures that show modifications related to age, mainly resulting in the reduction of the pulp chamber volume due to the continual deposition of secondary dentin. The study aims to evaluate the ...

considering the ease of isolation and high expansion potential of pulp stem/progenitor cells isolated from wisdom and primary teeth they have been implicated as the most reliable autologous cell source in dental tissue engineering. meanwhile, different isolation methods have remarkable impacts on the expansion potential of adult stem cells. in enzymatic digestion method extracted teeth as denta...

Considering that instrumentation of the apical foramen has been suggested for root canal infection control, this study analyzed the relationship between the files that bind at the apical foramen and the foraminal openings in 50 maxillary central incisors. After preparation of the pulp chamber, access to the canal was obtained with #1 and 2 LA Axxess and K-files with tip cut were inserted up to ...

Aim. To measure and validate the permeability of pressure changes in correlation to different root filling techniques. Methods. Eighty extracted single-rooted teeth were randomly assigned to one of eight groups of ten teeth. Following standardized instrumentation and irrigation, root canal fillings were performed using either cold lateral condensation, a warm carrier-based gutta-percha obturati...

AIM To examine the effect of inflammatory stimuli on the proliferation/migration of dental pulp stem cells by assessing the responses of stem cell-associated marker-expressing cells in rat incisors to lipopolysaccharide (LPS) stimulation in vivo. METHODOLOGY The crowns of rat incisors were removed, and the coronal pulp chamber was instrumented. After haemostasis, an absorbent point soaked in ...

BACKGROUND Corneal perforation in severe Stevens-Johnson syndrome (SJS) presenting great therapeutic difficulties, the imperative corneal transplantation always result in graft failure and repeated recurrence of perforation. The aim of this study was to evaluate the effectiveness of a modified small tectonic keratoplasty (MSTK) with minimal corneal graft in the management of refractory corneal ...

Abstract These case reports aimed to describe the management of lateral perforation in middle cervical third root two maxillary incisors with pulp canal calcification using Bio-C Repair, safe and viable clinical treatment strategies. Digital radiographic exams were obtained different angles analyzed filters. Cone-beam computed tomography (CBCT) images requested show actual position canal, locat...
