The extraction socket classification proposed here is an objective and helpful tool for socket assessment and for promoting future implant esthetics.

The aim of this study was to investigate the severity of infraorbital nerve injury following zygomaticomaxillary complex fractures and to estimate the treatment methods facilitating its functional recovery. A total of 478 patients with unilateral zygomaticomaxillary complex fractures were treated. Infraorbital nerve sensory disturbances were diagnosed in 64.4% of the patients. Injury of the infraorbital nerve was expressed as asymmetry index, which was calculated as a ratio between the affected side and the intact side electric pain detection thresholds at the innervation zone skin before treatment and 14 days, 1, 3, 6 and 12 months postoperatively. A mean asymmetry index of 0.6 +/- 0.03 and 1.9 +/- 0.5 was registered for 57 (11.9%) patients with hyperalgesia and for 251 (52.5%) patients with hypoalgesia, respectively. As a result of retrospective analysis of infraorbital nerve sensory disturbances and its functional recovery, infraorbital nerve injury severity was classified as mild, moderate and severe. It was found that the dynamics and outcome of the functional infraorbital nerve recovery depend on the severity of the injury and the presence of infraorbital canal damage. Function was completely recovered within 3 months after treatment in cases with mild nerve injury. In moderate cases, complete recovery was seen within 6 months and in 34.6% of the severe cases, within a 12-month period after treatment when infraorbital nerve decompression was performed according to the stated indication. Treatment based on infraorbital nerve injury classification offers a better prognosis for complete recovery of the infraorbital nerve function.

ObjectivesThe review aims to study dental implant placement purposefulness for patients who have been treated or are on treatment with bisphosphonate medication.Material and MethodsStructured search strategy was applied on electronic databases: MEDLINE, PubMed, PubMed Central and ResearchGate. Scientific publications in English between 2006 and 2017 were identified in accordance with inclusion, exclusion criteria. Publication screening, data extraction, and quality assessment were performed. Outcome measures included implant failure or implant-related osteonecrosis of the jaw.ResultsIn total, 32 literature sources were reviewed, and 9 of the most relevant articles that are suitable to the criteria were selected. Heterogeneity between the studies was found and no meta-analysis could be done. Five studies analysed intraoral bisphosphonate medication in relation with implant placement, three studies investigated intravenous bisphosphonate medication in relation with implant placement and one study evaluated both types of medication given in relation with implant placement. Patients with intraoral therapy appeared to have a better implant survival (5 implants failed out of 423) rate at 98.8% vs. patients treated intravenously (6 implants failed out of 68) at 91%; the control group compared with intraoral bisphosphonate group appeared with 97% success implant survival rate (27 implants failed out of 842), showing no significant difference in terms of success in implant placement.ConclusionsPatients treated with intravenous bisphosphonates seemed to have a higher chance of developing implant-related osteonecrosis of the jaw. The intraorally treated patient group appeared to have more successful results. Implant placement in patients treated intraorally could be considered safe with precautions.

Objective. The aim of this study was to analyze the factors that were associated with the development of osteomyelitis during the treatment of mandibular fractures. Material and Methods. The data of 3188 patients with mandibular fractures treated during 2002–2009 were analyzed. Traumatic osteomyelitis of the mandible was diagnosed in 207 patients. The background factors of complications were studied and compared with the control group (100 patients) not having complications after treatment of mandibular fractures. The data of clinical, roentgenologic, microbiological, and immunological investigations were analyzed. A logistic regression model was developed to identify the factors for osteomyelitis development. Results. The treatment in 6.5% of patients was complicated with osteomyelitis; 88.5% of these patients were men, and more than 80% of patients were younger than 50 years. In 86.8% of cases, Staphylococcus species were isolated, with Staphylococcus aureus accounting for 69.1% of cases. The following factors were found to be associated with osteomyelitis development: immunity dysfunction, caries-affected teeth at the fracture line, mobile fractured bones, bone fixation after more than 7 days following trauma, healthy teeth at the fracture line, insufficient bone reposition, and bone fixation after 3–7 days following trauma. Conclusion. Comparative analysis of factors influencing the treatment results revealed a great importance of immunological and dental status and microflora at the affected site. Insufficient or late reposition and fixation of fractured bone fragments play a significant role in the healing process.

ObjectivesThere aren’t any objective methods that may help in standard evaluation of oral surgery patient’s psycho-emotional status. Without any standardized evaluation, two main problems appear: heterogeneity between studies and ineffective patient’s evaluation. Therefore, Universal Scale in Oral Surgery (USOS) for patient’s psycho-emotional status rating has previously been proposed by authors. The aim of present study is to assess the clinical effectivity and validate the Universal Scale in Oral Surgery in case of outpatient tooth extraction for adult healthy patients.Material and MethodsClinical trial to validate the USOS for patient’s psycho-emotional status rating was performed. In total 90 patients, that came for outpatient dental extraction to Lithuanian University of Health Sciences Oral and Maxillofacial Surgery Department ambulatory, were enrolled in clinical trial. Patients filled self-reported questionnaires before the procedure. Operating surgeon rated USOS for patient’s psycho-emotional status rating doctor’s part questionnaire after the procedure. 4 - 6 weeks later all patients were asked to fill USOS for patient’s psycho-emotional status rating questionnaire retrospectively. ResultsAccording to the statistical analysis, the final composition of USOS for patient’s psycho-emotional status rating that would fit to reliability coefficient should be composed from 6 patient part questions and 3 general doctor part questions.ConclusionsUniversal Scale in Oral Surgery for patient’s psycho-emotional status rating is a novel, doctor and patient rated scale which is suitable for clinical and scientific usage.

Nacionalinės valdžios institucijos turi nustatyti sveika­tos tyrimų prioritetus ir priimti sprendimus dėl inves­ticijų į sveikatos sistemas ir sveikatos priežiūros prie­mones. Visuomenės sveikatos intervencijomis siekiama sumažinti gyventojų ligų naštą ir pagerinti gyvenimo kokybę. DALY yra priemonė kiekybiškai įvertinti ligų naštą, išreikštą populiacijoje prarastų metų dėl anksty­vos mirties ar negalios, skaičiumi. Darbo tikslas − teo­riškai pagrįsti DALY indeksą, jį interpretuoti ir pateikti apskaičiavimo bei praktinio panaudojimo pavyzdžių. Mokslinių straipsnių, publikuotų 1997–2021 m. laiko­tarpiu, ieškota MEDLINE, Google Scholar ir Science­Direct mokslinių duomenų bazėse. Paieškoje naudotos raktažodžių kombinacijos anglų kalba: DALY index, disability-adjusted life year, life expectancy, quality of life. Literatūros šaltiniai atrinkti remiantis šiais kri­terijais: straipsniai, kuriuose aprašomas DALY indek­sas; straipsniai, pateikiantys DALY indekso pritaikymo būdus; straipsniai, kuriuose apskaičiuojami DALY in­deksas. Rezultatai parodė daugybę skirtumų tarp in­tervencijos kainos ir sveikatos pagerėjimo. Nustatytas silpnas ryšys tarp intervencijos didesnės kainos ir pati­kimesnio sveikatos pagerėjimo, tačiau nerasta įrodymų, kad brangesnė intervencija sveikatą pagerintų labiau. Daromos išvados, jog DALY skaičiavimui reikalinga daugybė duomenų, kurie ne visada prieinami, o skai­čiavimas sudėtingas ir brangus. Be to, DALY nevertina ligonio galimybių gyventi su negalia ir daugelio kitų veiksnių, turinčių įtakos sveikatos politikos klau­simų sprendimui.
