Objective. To evaluate measures of the styloid process (SP) in Brazilian dry skulls. Methods. This study involves measurements of two points (lateral end posterior views) of 15 dry skulls held by the Morphology Department, Institute of Biological Sciences of Federal University of Minas Gerais. Results. There was a large variability for the length of left and right sides (in lateral and posterior views) of the styloid process. From the lateral view of the left and right styloid, the length of the SP ranged, respectively, from 10.22 mm to 69.73 mm and from 8.30 mm to 63.77 mm. From a posterior view of the left and right sides of the skulls, the values range, respectively, from 15.57 mm to 69.51 mm and from 15.64 mm to 69.44 mm. Conclusion. We believe that this study provides additional information about the frequency of elongated SP among the Brazilian population.
It was found that photobiomodulation with LASER and LED presented effects. However, only the LED demonstrated a beneficial effect on the process of bone repair in the dental alveoli of rabbits.
Aim: To evaluate medical records from patients who underwent abscess drainage due to odontogenic infections in a public hospital in the city of Belo Horizonte (Minas Gerais, Brazil) during the period of 2003 and 2013. Methods: A retrospective analysis of cases which required drainage of abscesses due to dental infections. The types of therapeutic procedures analyzed were endodontic drainage, intraoral mucosa drainage, periodontal drainage, and extraoral drainage. Results: 162,902 cases required dental assistance, and 32,352 cases required drainage of abscesses due to dental infections. The most frequent approach was endodontic drainage (21,313 procedures); the least frequent procedure was extraoral drainage (922 procedures). Conclusions: Odontogenic infection is a common clinical condition in dental clinics. It should be diagnosed and treated as quickly as possible to avoid or minimize progression to more severe cases.
Background : All types of graft materials undergo dimensional changes, and these can influence both the bone volume obtained after the procedure and the stability of implants installed in the posterior maxillary grafted region.Aim/Hypothesis : The objective of this study was to evaluate the dimensional stability of the Osteogen® biomaterial (Impladent, Ltd, Holliswood, NY), associated or not with Platelet and Leukocyte Rich Fibrin (L-PRF) in sinus lift, observing the repair period of 6 months.Material and Methods : As a methodology, a prospective, randomized clinical study was conducted in a split-mouth design. The tomographic exams were performed in the preoperative (T0), 10 days postoperative (T1) and 180 days postoperative (T2) days, in 20 individuals with bone reconstruction needs in the bilateral maxillary sinus, for posterior rehabilitation with implants. The height and volume of the grafts were evaluated in T1 and T2, as well as the calculation of the volumetric changes and height between the two study periods.Results : The reduction in height between T1 and T2 was statistically significant only in the test group and the volume contraction of the grafts did not present a statistically significant difference in the comparisons between groups or between men and women.
Conclusion and ClinicalImplications : Both grafts were effective for bone reconstruction in the maxillary sinus and after 6 months of healing, the addition of L-PRF to hydroxyapatite did not interfere in the percentage of graft volumetric contraction.
