  Objectives The aims of the present study were to evaluate the relative incidence of alveolar osteitis (AO) after mandibular third molar surgery, post-operative findings and local expression of bone markers and cytokines. Study design In 445 patients, unilateral surgical third molars extractions were undertaken (584 teeth). Bone markers and cytokines were explored at the AO side and on the un-operated contralateral side and compared with the levels in samples from a control group of 18 persons without AO. Results The relative incidence of AO was 4.6%. Patients (n = 27) with AO were invited to participate in the study and 21 (77.8%) did so. Patients with AO had 1–4 extra visits for treatment of AO, the mean follow-up time was 2.6 days for all patients. There were significantly higher levels of bone markers and cytokines in the AO site compared with the un-operated contralateral site, except for Epidermal growth factor (EGF). No significant difference in expression of bone markers and cytokines between the AO and control groups was found. Lower maximum inter-incisor opening (MIO) was correlated with increased Macrophage inflammatory protein 1 alpha. A negative correlation between patients’ complaint of trismus and MIO was seen. Conclusions The relative incidence of AO was low in our patient group treated with surgical removal of third molars. AO was more frequently seen in female patients. Treatment of AO required up to four extra visits. The study provides some information on the role of cytokines in AO; but further studies are required.

  Objectives Our aim was to investigate the effect of an oxytetracycline-impregnated gauze drain on the incidence of alveolar osteitis (AO) and postoperative pain during the first week after mandibular third molar surgery. Study Design Two hundred consecutive patients undergoing third molar surgery under local anesthesia were randomized into a drain group (n = 100), with an oxytetracycline-impregnated drain placed in the extraction socket, and a control group (n = 100). An experienced surgeon performed the surgery. Systemic antibiotics were not used. Results The incidence of AO was 23% in the control group and 5% in the drain group (P < .001). The risk of developing AO was approximately 6 times higher in the control group, and females had a 2.5 times higher risk compared with males. Patients in the control group had significantly more pain on the day of surgery and on days 4 to 7. The presence of AO was associated with continued use of analgesics (P < .001). No patients experienced postoperative infections or had complications requiring hospitalization. Conclusions The present study showed that an oxytetracycline-impregnated drain significantly reduced the incidence of AO after third molar surgery. The described treatment strategy, without the use of systemic antibiotics, seemed efficient in lowering overall postoperative morbidity and downtime after third molar surgery.

  Redusert benvolum er en vanlig problemstilling ved vurdering av implantatbehandling. Rekonstruksjon av kjevekamsatrofi med 3D-fremstilt titanmesh (titannett) er en videreutvikling av tidligere benyttede teknikker for rekonstruksjon av kjevekam. En 52-årig kvinne ble henvist til Avd. for oral kirurgi og oral medisin, Institutt for Klinisk odontologi (IKO), UiO, med ønske om implantatbehandling posteriort i atrofisk mandibel. Det ble utført rekonstruksjon av kjevekammen med titannett og implantatinstallasjon. Behandlingsforløpet gikk over 14 måneder og total oppfølgingstid etter implantatinstallasjon er 12 måneder.

  Aims: In clinical research, primary registration of data in computer-based software reduces the workload for the clinician and facilitates exporting data for further analysis. Software available for this purpose should be user friendly and provide secure storage. University Health Network (UHN) is an interactive software launched by the University of Oslo and other European universities. UHN allows anonymized patient data to be shared across universities and enables creation of questionnaires to be used in clinical research (InReach). We report our initial experience with InReach in a prospective study of morbidity after mandibular third molar surgery in our department from September 2012-August 2013. Materials and Methods: Patients were seen one week postoperatively. Data were recorded using an InReach-based questionnaire. The study was approved by the Norwegian Social Science Data Service. Collected data were consolidated and exported for statistical analysis in SPSS. Results: A total of 527 surgeries were performed within the time frame, of which 397 were registered in InReach. This gave an inclusion of 75%. Even though most patients consented to participate in the study, many were not registered in InReach due to neglectance from the clinicians. Coincidentally, a retrospective study of nerve injuries after mandibular third molar surgery, performed within the same period, showed a possible tendency for lack of recording these complications in InReach. Four patients with nerve injuries had not been included in the InReach-based prospective study. Conclusions: UHN is in our experience easy to use and provides the researcher with instant access to the registered patient data. It facilitates data recording in the clinical setting and later consolidation of data and export to appropriate software for statistical analysis. Constant motivation of the clinicians examining the patients is important to secure patient inclusion and recording of clinical data. Unfortunately, computerized registration does not correct for human errors.
