Objectives: Preemptive analgesia consists in administering analgesic prior to surgery in order to prevent peripheral sensitization phenomenon which leads to high painkiller intake in the postoperative period. Ketoprofen is a widely used analgesic in the third molar surgery. However, it is not yet clear if ketoprofen administered before surgery may decrease postoperative pain sensations and analgesic intake. The aim of the study was to evaluate the effectivenness of preemptive ketoprofen analgesia in the third molar surgery. Methods: The study protocol followed a prospective, randomised, double-blinded clinical test. The basic criterion for including a patient in the study was a need for surgical extraction of a retained lower third molar, which was not the cause of inflammation. One hundred healthy individuals volunteered with a signed document were randomly allocated into three parallel groups: – group A: patients receiving 100 mg of ketoprofen 60 minutes preoperatively and 100 mg of placebo 60 minutes postoperatively; – group B: patients receiving 100 mg of placebo 60 minutes preoperatively and 100 mg of ketoprofen 60 minutes postoperatively; – group C: patients receiving 100 mg of placebo 60 minutes preoperatively and postoperatively. Every patient were given 50 mg ketoprofen capsules as a rescue medication and asked to note every episode that induced them to take it. Total analgesic intake in 7-day postoperative period was recorded. Moreover, during first 12 hours postsurgery patients recorded pain sensations on the VAS in 60-minute intervals. Results: The particular results will be presented.
P.217 Primary stability of the endooseos dental implants V. Palarie, C. Bicer. State University of Medicine and Pharmacy N. Testemuitanu, Orhei, Moldova Objectives: insertion of dental endooseos implants must be finished with a perfect anchorage into the maxillary bone, what will insure an immediately stability after operation, which is named primary stability. Primary stability is necessary in osteointegration of dental implants in two stages. It has more importance in case of one stage implants. Aim of study was objectively appreciation of the bone density influence in case of implantation of one stage implants. Methods: at 76 persons were installed 190 conical screw type implants with 4.0 mm and 4.2 mm in diameter. At upper jaw were implanted 85 implants and at mandible – 105 implants. 70 implants were 10 mm in length, 30 implants – 11.5 mm and 12 mm in length – 90 implants. Bone density was appreciated during of implants surgery after Misch?s method. The value of primary stability in vestibulo-oral direction and in the axe of implant was determined with Periotest device. Results: 80 implants were inserted in bone with density D2, 71 with density D3 and 19 with density D4. 20 implants were installed in bone with density D1. Conclusions: it was determined that bone density influences in the directly mode primary stability of the dental implants. This correlation is more pronounced in the mandible. Primary stability of the implants in the axial direction had the value between −6 and −9.
Purpose: Pathologic assessment of cervical lymph nodes in surgical specimens can be inaccurate; therefore, examining a greater number of nodes may increase the likelihood of proper disease staging of head and neck cancer. The estimated 2-year cumulative and disease-free survival were determined in a cohort of patients who had a variable count of excised negative nodes after surgery for early stage oral cavity cancers. Methods: Fifty-two patients out of 526 individuals with carcinoma of the oral cavity between 1998 and 2005 had undergone primary tumor resection and lymph node dissection of the neck for stage I or II disease. With a mean count of 27 examined negative nodes, cases were separated into groups with 27 and >27 uninvolved lymph nodes and compared. Endpoints of analysis were the 2-year rates of tumor relapse or progression and cumulative survival. Results: The mean age of study subjects was 59 years, and 77% of them were men. During a median follow-up period of 27 (range 1–108) months, tumor recurred or progressed in 10 patients (19%). The 2-year survival rates were 78% and 82% in individuals with 27 and >27 uninvolved node counts respectively (p > 0.65); the corresponding 2-year disease-free survival rates were 75% and 78% (p > 0.78). Multivariate analysis revealed that extent of neck dissection independently affected overall or disease-free survival. Conclusion: The favorable survival observed in our patients with resected early stage oral cavity cancers and negative cervical lymph nodes are in accord with other studies. However, based on limited retrospective data, the prognostic impact of the count of examined uninvolved nodes remains to be ascertained. P.219 Radiographic diagnosis of mandibular fractures T. Boye, N. Malhi. Chesterfield Royal Hospital, Chesterfield, UK Aim: The aim of this study was to ascertain whether lateral oblique radiographs are comparable to orthopantomograph (OPT) in diagnosing mandibular fractures. Method: A retrospective review was conducted of all the mandibular fractures that required surgical correction at CRH between 1st November 2006 and 31st October 2007. All the patients were anonymised and placed into a random order. Firstly, all the lateral oblique radiographs available were reviewed and any fractures (including laterality) were recorded. Secondly, all OPTs for the same patients were reviewed for fractures. The process was carried out by a first-year SHO and also by a Specialist Registrar in Maxillofacial Surgery. Results: Twenty six patients identified during the study period. On lateral oblique views, 30% of the fractures were diagnosed correctly by the SHO and 48% were diagnosed correctly by the SpR. However, on the OPT views, 76% of fractures were diagnosed correctly by the SHO and 94% were diagnosed correctly by the SpR. Conclusion: OPT is better at diagnosing mandibular fracture compared with lateral oblique radiograph. P.220 Retrospective study of mouth floor cellulitis in 2003–2006 R. Seselgyte, R. Rasteniene.
