Abstract Objective: Several patients and operator related factors have been confirmed to be of importance for blood loss in orthognathic surgery, e.g., type of surgical intervention and operative time. However, the surgeon's impact has been studied only to a limited extent. Thus, the primary aim of this study was to evaluate the surgeon's impact on intraoperative blood loss. Methods: Clinical data was gathered retrospectively for all osteotomies performed by three different experienced surgeons between January 1 st , 2013 to December 31 st , 2016 at a regional centre for orthognathic surgery at the Sahlgrenska University Hospital, Gothenburg, Sweden. Results: A total of 179 patients (92 women and 87 men) who underwent Le Fort I osteotomy, Bilateral Sagittal Split osteotomy, or Bi-maxillary osteotomy were included. No statistically significant difference was seen between the three surgeons for intraoperative blood loss. Conclusion: Intraoperative blood loss during orthognathic surgery is not operator dependent when experienced surgeons are compared.","PeriodicalId":326702,"journal":{"name":"Journal of Dental and Maxillofacial Research","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132431184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hill","doi":"10.31038/jdmr.2021425","DOIUrl":"https://doi.org/10.31038/jdmr.2021425","url":null,"abstract":"Bioactive silicate glass-based (PerioGlas®) has been previously used to enhance periodontal bone regeneration. However, the degradation of this glass in the body fluid generates a high pH (>8) which may enhance the growth of periodontopathic bacteria, such as Porphyromonas gingivalis ( P. gingivalis ) thereby inhibiting osteoblastic activity. The aim of this study was to: (i) develop a mixture of a phosphate and silicate glass to produce a more neutral pH environment where the alkaline pH arising from the bioactive silicate glass can be offset by the acidity of phosphate glass, (ii) whether the alkaline phosphatase enzyme (ALP) when added to the silicate/phosphate glass mixture can enzymatically hydrolyse the Q2 metaphosphate chains to release Q0 orthophosphate species that can be used in forming apatite and bone mineralization. For this purpose, nine compositions of bioactive silicate/ phosphate glass-mixtures were prepared. The glass bioactivity was performed by immersing the prepared glass mixtures in ALP containing Tris buffer solution. The pH change in solutions was measured as a function of time. The glass mixtures degradation and apatite formation were investigated by 31P Solid and 31P Solution Nuclear Magnetic Resonance (NMR) spectroscopies. The results showed that the pH behaviour was modulated by immersing the glass-mixtures in buffered solutions. Solid and Solution NMR revealed that the terminal Q1 species belonging to the Q2-metaphosphate chains was hydrolysed by the ALP and converted into a Q0 orthophosphate species. In conclusion, the glass mixtures regulated the pH through its degradation stepwise on immersion. The output of the NMR spectra significantly supported the enzymatic degradation of glass mixtures with ALP enabling apatite precipitation for new bone formation. The concept of using silicate/phosphate glass mixtures with ALP is innovative and pioneering technology, suggesting its potentiality to develop new biomedical materials for different applications.","PeriodicalId":326702,"journal":{"name":"Journal of Dental and Maxillofacial Research","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133371107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It assessed compliance with Pennine Care local guidelines including: • The justification for GA • Attendance at a dedicated POA • Pre-operative radiographs and their justification • Pre-operative restorations • Were patients caries free following GA? • Were guidelines adhered to when extracting FPM’s including orthodontic considerations? • Were first permanent molars balanced/compensated where appropriate? • Were all poor prognosis deciduous teeth extracted under GA? • Was appropriate consideration given to balancing/compensating extractions? • Record keeping standards • Were patients appropriately discharged/reviewed? Results were varied and showed good compliance with some parts of the guidelines such as 70/71 (98.6%) patients having dedicated POA in the re-audit. The percentage of patients with a dedicated oral health appointment rose from 13.9% (11/79) for Cycle 1 to 38.0% (27/71) for Cycle 2 which is a 24.1% improvement. The percentage of patients without documented justification for a lack of radiographs dropped from 26.5% (9/34) for Cycle 1 to 9.1% (3/33) for Cycle 2. This shows a 17.4% improvement. There were improvements in the numbers of patients having appropriate balancing extractions for unilaterally carious deciduous canines: 6/9 (66.7%) for Cycle 1 and 11/13 (84.6%) for Cycle 2. This shows an improvement of 17.9% 24/26 of patients (92.3%) in Cycle 2 who had planned extraction of FPM’s had pre-operative x-rays and there were some improvements in the number of patients with documented orthodontic considerations compared to Cycle 1. For example: The number of patients with documented assessment of crowding rose from 16.7% (4/24) in Cycle 1 to 85.2% (23/27) in Cycle 2. This is a 71.8% improvement. The percentage of patients who were advised of the risk of future mesial tipping or malocclusion of the second permanent molars rose from 8.3% (2/24) in C1 to 57.7% (15/26) in C2. This is a 49.4% improvement. 94.3% (67/71) of patients were caries free following completion of GA in the re-audit whereas the target is 100%. However, some of these findings appear to be record keeping errors. Greater consistency is needed regarding record keeping as well as the post-operative review/discharge process. A greater awareness of the guidelines would be helpful.","PeriodicalId":326702,"journal":{"name":"Journal of Dental and Maxillofacial Research","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129281769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods: The questionnaire was divided in two main sections and included multiple choice and/or open/closed questions. The first section consisted of six questions and was designed to collect demographic data of the sample and the second section, consisting of 15 questions, included general questions regarding periodontal regeneration procedures and questions based on specific clinical cases. 200 questionnaires were distributed at selected venues in Greece by the investigators. The participants were given one month to complete and return to the questionnaires to the School of Dentistry in Thessaloniki. Statistical analysis: Data management and analysis was performed using both Microsoft Excel 2007® (Microsoft Corporation, Reading, UK) and SPSS® version 22.0 software (IBM United Kingdom Ltd, Portsmouth, UK). Frequencies and associations between the demographic profiles of the participants were evaluated and presented in the form of frequency tables, charts, and figures. Results: 104 questionnaires (67 males, 37 females: mean age 43.2 years [±9.8]) (52% response rate) were received. Of those who responded 56.7% (n=59) specialized in Periodontics and 43.3% (n=45) specialized in a variety of other dental disciplines (General Dentistry, Oral Surgery and Implantology). Guided tissue regeneration procedures and the use of enamel matrix derivative were recommended for the reconstruction of bony defects and both subepithelial connective tissue graft and coronally advanced flap with or without enamel matrix derivative were the most popular choices for root coverage. Smoking was considered a contraindication by most of the participants and conflicting responses were given regarding the use of antibiotics as part of the post-operative care following regenerative procedures.","PeriodicalId":326702,"journal":{"name":"Journal of Dental and Maxillofacial Research","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116879147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Supported by in vivo and in vitro studies, we highlight emerging–targeting strategies for physical and mechanical therapies intended to limit biofilm formation. Nevertheless, many challenges to eradicating mature biofilms are discussed. Conclusions: Oral biofilms in the denture wearer can be controlled with daily hygiene but cannot be totally eradicated. To prevent the pathogenesis of denture biofilm, the biomass on the denture surface and the bioburden in the oral cavity must be reduced focusing on not only the inhibition of putative pathogens, but also interference with environmental factors that drive selection and enrichment. Clinical implications: An effective oral hygiene regimen targeting dentures, saliva planktonic cells, mucosa, and the remaining teeth, whether or not they are affected by periodontal diseases, is necessary to control biofilm, particularly in the presence of many general diseases.","PeriodicalId":326702,"journal":{"name":"Journal of Dental and Maxillofacial Research","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126490551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
