The Effects of CO2 Laser with or without Nanohydroxyapatite Paste in the Occlusion of Dentinal Tubules
The aim of this study was to evaluate a new treatment modality for the occlusion of dentinal tubules (DTs) via the combination of 10.6 µm carbon dioxide (CO2) laser and nanoparticle hydroxyapatite paste (n-HAp). Forty-six sound human molars were used in the current experiment. Ten of the molars were used to assess the temperature elevation during lasing. Thirty were evaluated for dentinal perme...
متن کاملInvasion of dentinal tubules by oral bacteria.
Bacterial invasion of dentinal tubules commonly occurs when dentin is exposed following a breach in the integrity of the overlying enamel or cementum. Bacterial products diffuse through the dentinal tubule toward the pulp and evoke inflammatory changes in the pulpo-dentin complex. These may eliminate the bacterial insult and block the route of infection. Unchecked, invasion results in pulpitis ...
متن کاملPresence of Bacteria in Dentinal Tubules
This study demonstrated that a significant number of bacteria is present in the radicular dentinal tubules of periodontally diseased human teeth. Ten periodontally diseased teeth were prepared and stained by Brown and Brenn technique for histological examination. Bacteria were detected in all teeth. It is suggested that bacteria may invade dentinal tubules exposed to periodontal pocket and are ...
متن کاملDiffusion ability of endotoxin through dentinal tubules.
The aim of this study was to evaluate the ability of endotoxin to diffuse through dentinal tubules towards the cement and to observe the period of time needed for it to reach the external root surface. Thirty single-rooted human teeth had their crowns and apices removed in order to standardize the root length to 15 mm. Teeth were instrumented until #30 K-file and made externally impermeable wit...
متن کاملUltrastructure of odontoblasts in dentinal tubules of mice.
The presence of odontoblasts in dentinal tubules has been noted by numerous investigators. One of the first to describe their presence was B. Orban (l Dent Res 20:553-557, 1941). The cells were in tubules associated with forceps marks on the root surfaces. Odontoblasts in dentinal tubules have been reported due to various types of trauma to pulps. Cavity preparation (V. E. JAMES and I. SCHOUR, ...
