Study design. Two calvarial defects, 5 mm diameter, were prepared in parietal bone. The left defects were filled with natural bovine bone mineral (NBBM) and the right defects were left untreated. The first group did not receive fluoxetine. The second group and the third group received
7.5 mg and 15 mg flouxetine, respectively, daily by gastric gavage. The animals were killed 8 weeks after surgery, and the amount of bone regeneration was evaluated using histometric analysis.
Results. The Pevonedistat in vitro defects showed dose-dependent increase in bone formation. The bone fill length had statistical significant differences between NBBM/flouxetine (15 mg) group and other groups (P < .05). The presence of the NBBM had positive effect on the bone formation in all groups in so far as the maximum amount
of the increasing effect was seen in those rats filled with NBBM that received 15 mg flouxetine (P < .05). The minimum bone length in fluoxetine-treated defects was seen in 7.5 mg defects (0.36 mm)
Conclusion. Fluoxetine may improve the amount of bone regeneration in the rat calvarial defects. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod this website 2009; 108: 22-27)”
“The optical transmission spectrum of [111](c) poled relaxor-based ferroelectric single crystal 0.93Pb(Zn1/3Nb2/3)O-3-0.07PbTiO(3) (PZN-0.07PT) was measured in the range of ultraviolet to near infrared. The optical absorption edge has been determined and
the wavelength dependence of the absorption coefficient was calculated. The direct energy gap E-gd=3.144 eV, indirect energy gap E-gi=2.915 eV, and phonon energy E-p=0.097 eV (or 782 cm(-1)) were determined based on the theory of band to band transitions. It was also confirmed by Raman spectra that the indirect transition for the [111](c) poled PZN-0.07PT single crystal is mainly due to the contribution of 780 cm(-1) phonon corresponding check details to the Nb-O-Zn bond stretching mode.”
“Objective. A tooth with a dentigerous cyst (DC) does not always erupt by marsupialization. The eruption duration and conditions of DC-associated premolars were examined to predict such eruption following marsupialization.
Study design. The eruption and conditions including depth, root formation, inclination, and eruption space were examined retrospectively in 21 DC-associated mandibular premolars using dental and panoramic radiograms.
Results. Fifteen of 21 premolars erupted half within 3 months and all 15 erupted completely within 10 months after marsupialization, without orthodontic traction. The age of the patients, tooth depth, and inclination were significantly different between the erupted and non-erupted groups, whereas there was no significant difference in the root formation or the eruption space between the 2 groups.
Conclusions. The successful eruption of a DC-associated premolar can be predicted within 3 months after marsupialization.
