1. Spectrophotometric analysis of crown discoloration induced by MTA- and ZnOE-based sealers
Crown discoloration can be induced by root canal sealer remnants following root canal treatment. Objective: The aim of this study was to evaluate chromatic alterations in human tooth crowns induced by a Mineral Trioxide Aggregate-based sealer (MTA Fillapex®) and a commonly used ZnOE-based sealer (Roth-811). The tested null hypothesis was that the applicati

2. Influence of different durations of estrogen deficiency on alveolar bone loss in rats
The purpose of this study was to morphometrically evaluate the influence of different durations of ovariectomy-induced estrogen deficiency on alveolar bone loss associated with ligature-induced bone loss in rats. Sixty female Wistar rats were randomly assigned to ovariectomy (OVX test group) or sham operation (SHAM control group). The OVX and SHAM groups wer

3. EFEITOS DE AGENTES CLAREADORES EXTERNOS NOS TECIDOS DENTÁRIOS E NA JUNÇÃO AMELOCEMENTÁRIA / Effects of external bleaching agents on dental tissues and the cementoenamel junction
Evaluate with a scanning electron microscope the alterations occurring in enamel, cementum and cementoenamel junction after the use of different external bleaching agents. Fifteen healthy pre-molars were sectioned in the middle with the aid of a cutting machine (Labcut 1010), in the longitudinal direction along the axis of the teeth, obtaining mesial and dis

4. An autoradiographical study of [3H]thymidine incorporation into subcutaneously transplanted mouse molar teeth. Cell proliferation and migration in transplanted teeth.
Mice bearing either allografts or isografts of 10 day old molar teeth were injected with [3H]thymidine to identify proliferating and migrating cells within the graft and surrounding tissues. In isografts proliferating cells were found successively in the area underlying the cervix, in the cervical pulp and the coronal pulp. However, cells did not migrate fro
