Delayed Removal of a Maxillary Third Molar Accidentally Displaced Into the Infratemporal Fossa
The removal of an impacted maxillary third molar is an easy procedure for an oral and maxillofacial surgeon. The most commonly seen complications associated with this type of surgery are excessive hemorrhage, infection, pain, swelling, trismus, and root fractures. Although rarely encountered, unexpected complications may also arise during this procedure, such as the displacement of the tooth into an anatomic space. In this article, a case of a maxillary left third molar accidentally displaced into the infratemporal fossa is presented, and the delayed removal of the tooth after 3 weeks from the initial unsuccessful attempt is described, along with the correlating reasons. The role of the radiologic analysis in determining the localization of the tooth, including the routine panoramic radiographs and more importantly the volumetric computed tomographic scans, is stated. The different surgical treatment options are classified, and the potential for morbidity in the surgical removal of the tooth from the infratemporal fossa is presented by ranging the vital anatomic structures running through it
A retrospective analysis of sandblasted, acid-etched implants with reduced healing times with an observation period of up to 5 years
Purpose: The aim of this study was to evaluate the success rate of 2 different implant systems with sandblasted and acid-etched modified surfaces loaded after reduced healing periods. Materials and Methods: One-hundred seventeen patients with a mean observation period of 3.75 years (24 to 61 months) were included in this evaluation. Chart reviews of a standardized recall program were evaluated. All 532 placed implants showed an unloaded healing time of 6 weeks in the mandible and 12 weeks in the maxilla. At abutment placement a torque value of 35 Ncm was one of the primary variables, and the success of the implants over time was determined by the criteria of Buser et al. The survival was analyzed using Kaplan-Meier method, and the probability of an event within 1 group independent of time was evaluated using the chi-square test and Fisher exact test. Results: Of the 532 implants, 235 were placed in female and 297 in male patients; 448 implants were located in the maxilia and 84 in the mandible. Three implants were lost prior to abutment connection in 3 patients. Life table analyses show an overall success rate of 99.4% at 5 years, as no implants were lost after abutment connection. There was no significant association of the implant type (P =. 185), gender (P =. 99), or jaw (maxilla/mandible; P =.06) and the survival of the implants within this study. Conclusion: Based on the data found in this investigation, it can be concluded that implants with sandblasted, acid-etched surfaces can be restored after a 6- to 12-week healing period with a high predictability of success
Intra-articular injection of dexketoprofen in rat knee joint : Histopathologic assessment of cartilage & synovium
Background objectives: Effective pain control following outpatient surgical procedures is an important aspect of patient discharge. This study was carried out with an aim to investigate the histopathological effects of intra-articular dexketoprofen trometamol injection in knee joint on synovium and cartilage in an experimental rat model
Intra-articular injection of dexketoprofen in rat knee joint : Histopathologic assessment of cartilage & synovium
Background & objectives: Effective pain control following outpatient surgical procedures is an important aspect of patient discharge. This study was carried out with an aim to investigate the histopathological effects of intra-articular dexketoprofen trometamol injection in knee joint on synovium and cartilage in an experimental rat model.
Methods: In each of 40 rats, the right knee was designated as the study group and the left knee as the control group (NS group). Under aseptic conditions, 35 rats received an injection of 0.25 ml (6.25 mg) dexketoprofen trometamol into the right knee joint and an injection of 0.25 ml 0.9 per cent normal saline solution into the left knee joint. On the 1 st , 2 nd , 7 th , 14 th , and 21 st days after intra-articular injection, rats in specified groups were sacrificed by intraperitoneal injection of 120 mg/kg sodium thiopental. Knee joints were separated and sectioned for histopathological examination. Inflammatory changes in the joints were recorded according to a grade scale.
Results: No significant difference in terms of pathological changes both in synovium and cartilage was observed between the NS group and the study group on days 1, 2, 7, 14 and 21 after intra-articular injection of dexketoprofen or saline in the knee joint.
Interpretation & conclusions: The findings showed no evidence of significant histopathological damage to the cartilage and synovia for a period up to 21 days following intra-articular administration of dexketoprofen trometamol in the knee joints of rats
