Öğe Comparison of three pain scales after impacted third molar surgery(MOSBY-ELSEVIER, 2011) Isik, Kubilay; Unsal, Alkim; Kalayci, Abdullah; Durmus, ErcanObjective. Recently, a pain assessment scale called "full cup test" (FCT) has been suggested for pain evaluation. It is claimed to be easier to use for the patient, and it allows using parametric tests for statistical analyses. The aim of this study was to evaluate the validity of the FCT in third molar surgery. Study design. The FCT was compared with 2 well accepted pain scales. Forty-eight patients who had fully impacted lower third molars were included. All patients were asked to fill 3 pain scales-visual analog scale (VAS), verbal rating scale (VRS), and FCT-daily during the first postoperative week. Then the scales were collected and data statistically analyzed. Agreement among VAS, VRS, and FCT was evaluated using the Spearman rank coefficient. Results. Correlations among 3 scales were very high and significant (P < .001). Conclusions. The FCT can be used to assess the postoperative pain after third molar surgery.

The aim of this study was to determine the resistance and fracture strength values of the bone with the use of biomechanical tests in different consolidation periods of mandibular distraction osteogenesis. Study Design. In this study, 21 mature male New Zeland rabbits were used. After distraction, rabbits were separated into 3 groups to experience 4, 8, and 12 weeks' consolidation periods. Nonoperated hemimandibles of 6 rabbits were used as a control group. After 5 days' latency period, 0.5-mm distraction was applied twice a day, i.e., 1 mm/d lengthening. After the 5-mm lengthening application, we left the animals for 1, 2, or 3 months of consolidation period. Bending stress and strength values of the bone at fracture point were measured with the use of a 3-point bending test. Results. There were significant differences between the control and 3 study groups regarding bending stress and strength values. In addition, each study group was significantly different from each other. Conclusions. Bending stress and fracture strength of the bone may not reach that of normal bone after completion of 3 months' consolidation. It should be considered to keep in place extraoral appliances or comfortable intraoral distractors for a long period.

This study was planned to present benefits that we could obtain with low burden of drug. Study Design: Effects of drugs, which were administered preemptively before the procedure, on pain, mouth-opening limitation, and swelling were assessed by visual analogue scale (VAS), magnetic resonance imaging (MRI), and mouth-opening measurement. Following surgery, time intervals when the patients first need to receive the drug were measured. Results: The VAS scores of the patients were lower in the side treated with DT than that in the paracetamol treated side. There was no significant difference between the groups in terms of mouth-opening limitation. MRI recordings revealed that swelling was lower in the side treated with paracetamol than DT treated side. Conclusions: Administration of the drugs before surgery contributed to the postoperative patient comfort. The analgesic activity of 12.5 mg dose of DT was similar to, even better than, the analgesic activity of 500 mg dose of paracetamol; however, DT had insufficient anti-inflammatory efficacy.Öğe Evaluation of the biocompatibility and osteoproductive activity of ostrich eggshell powder in experimentally induced calvarial defects in rabbits(WILEY, 2008) Durmus, Ercan; Celik, Ilhami; Aydin, M. Faruk; Yildirim, Guelsuen; Sur, EmrahThe purpose of this study was to investigate the beneficial effects of particulate ostrich eggshell grafting on the healing of experimentally induced skull defects. The clinical, radiological, histological, and histomorphometrical findings of this material were compared with the results of commercially available demineralized bone matrix (DBM). The study was conducted on 18 adult New Zealand rabbits. One defect served as a control and the remaining ones either were filled with different sized eggshell particles or DBM, in each animal. Clinical and radiological inspections and histologic investigations of the animals were done at the 1st, 3rd, and 6th months of postoperative period. Radiologically, minimal bone regeneration was observed at the empty, control defect sites. The most advanced bone regeneration was in the DBM grafted defects. The eggshell particle grafted defect sites displayed weak bone regeneration at earlier stages, at 1st and 3rd months after operation when compared with demineralized bone matrix. Nevertheless, ossification was satisfactory at 6th month after operation when compared with the control defects. Within the limitations of this study, it was concluded that Ostrich eggshell powder (OSP) is a worth-while bone substitute because it is a safe, cheap, and easily available material. Long-term studies will clarify its possible role in maxillofacial surgery. Further sophisticated experiments should be undertaken before human implantation concerning its osteoproductive activity alone or in combination with other materials.

Materials and Methods: Fourteen patients (15 joints), with a mean age of 46.1 years, undergoing metal fossa eminence hemijoint replacement surgery, participated in this study. Each patient's jaw motion was recorded using an electromagnetic tracking device and patient-specific computed tomography images. A visual analog scale patient response questionnaire was used before and after the operation to assess the subjective outcome of the surgery. Results: The mean linear distance (LD) traveled by the incisors increased significantly due to the surgical intervention, from 30.4 +/- 6.9 mm preoperatively to 35.5 +/- 5.3 mm postoperatively (P = .02). The LD of the operated condyle decreased from 14.1 +/- 5.7 mm to 11.4 +/- 6.2 mm, but this was not significant. The mean LD for the unoperated condyle remained similar (preoperative, 13.2 +/- 5.9 mm; postoperative, 13.3 +/- 6.5 mm). The total mandibular rotation increased significantly, from 19.3 +/- 4.9 degrees preoperatively to 24.8 +/- 3.9 postoperatively (P < .01). Conclusions: Kinematic data support the functional efficiency of hemijoint replacement surgery, with benefits of increased maximal mouth opening, preservation of operated and unoperated condyle translation motion, and increased mandibular rotation.

Materials and Methods: Mandibular kinematic motion data and patient-specific computed tomography (CT) data were acquired. Patients were fitted with custom dental stents that were embedded with metal markers to link the mandibular kinematics data with the 3-dimensional TMJ CT images. An electromagnetic tracking device was used to collect kinematic motion data during maximal mouth opening and closing. The coordinate systems of the kinematic data and CT data were registered to calculate the motion of the mandibular condyle. Results: This technique was successfully used to study patients with motion aberration of the TMJ due to osteoarthritis. A typical case is illustrated in which the motion of both mandibular condyles was simulated preoperatively and postoperatively. Conclusions: The results of this study suggest that it is possible to use the proposed methodology to accurately quantify the motion of the mandibular condyle in 3 dimensions. The developed technique is user-friendly and noninvasive to the patient. The proposed methodology is a potential clinical tool that may be used in the management of patients with TMJ dysfunction.

Paresthesia is defined as a burning or prickling sensation or partial numbness caused by neural injury. Paresthesia in dentistry can be caused by local or systemic factors. Local factors include traumatic injuries such as mandibular fractures, expanding compressive lesions (benign or malignant neoplasia and cysts), impacted teeth, local infections (osteomyelitis, periapical, and peri-implant infections), iatrogenic lesions after tooth extractions, anesthetic injection, endodontic therapy (overfilling and apical surgery), implantology, orthodontic surgery, and preprosthetic surgery. The main purpose of this case report is to present the treatment and resolution of a mental nerve paresthesia stemming from apical pathosis of a mandibular canine tooth and the follow-up of 3 years.
