In relation to a diagnosis of peri-implantitis, a high likelihood of comorbidity was expressed by a history of periodontitis and a history of cardiovascular disease.

Bovine xenograft provided more radiographic bone fill than AB. The success for both surgical regenerative procedures was limited. Decreases in PD, BOP, and suppuration were observed.

Objectives: To assess if (I) the alveolar bone defect configuration at dental implants diagnosed with peri-implantitis is related to clinical parameters at the time of surgical intervention and if (II) the outcome of surgical intervention of peri-implantitis is dependent on defect configuration at the time of treatment. Materials and methods: In a prospective study, 45 individuals and 74 dental implants with ≥ 2 bone wall defects were treated with either an autogenous bone transplant or an exogenous bone augmentation material. Defect fill was assessed at 1 year. Results: At baseline, no significant study group differences were identified. Most study implants (70.7%, n = 53) had been placed in the maxilla. Few implants were placed in molar regions. The mesial and distal crestal width at surgery was greater at 4-wall defects than at 2-wall defects (p = 0.001). Probing depths were also greater at 4-wall defects than at 2-wall defects (p = 0.01). Defect fill was correlated to initial defect depth (p < 0.001). Defect fill at 4wall defects was significant (p < 0.05). Conclusions: (I) The buccal-lingual width of the alveolar bone crest was explanatory to defect configuration, (II) 4wall defects demonstrated more defect fill, and (III) deeper defects resulted in more defect fill.

AimPressure injuries as an indicator measuring the quality of nursing care and patient safety is a major health care problem worldwide. The aim of this study was to assess the knowledge, attitude and behaviour of nurses in preventing pressure injuries.DesignDescriptive cross‐sectional study.MethodsThis descriptive cross‐sectional study enrolled 214 registered nurses in Iran. Patient satisfaction was assessed using pieker pressure ulcer knowledge test, attitude towards pressure ulcer tool and behaviour of pressure ulcer questionnaire. Data analysed by SPSSv.24 applying descriptive and inferential statistics.ResultsThe mean scores of knowledge, attitude and behaviour of nurses on the prevention of pressure injury were 27.24 (SD 5.23), 38.55 (SD 6.43) and 51.24 (SD 7.54), respectively. There was a correlation between knowledge, attitude and behaviour with the history of pressure injury training. Also, there was a significant relationship between knowledge with educational level and attitude with work experience. Knowledge, attitude and behaviour of nurses were in moderate level. Necessary measures to overcome problems such as the availability of pressure reducing equipments, motivating the nurses, eliminating the shortage of nurses and empowering nurses by holding practical workshops are important in providing patients safety.

Peri-implantitis is a complication following implant therapy affecting soft and hard tissues around dental implants (Berglundh et al., 2018). In a recent systematic review and meta-analysis, the estimated weighted mean prevalence of peri-implantitis at a patient level was reported to be 22% (CI: 14%-30%) (Derks & Tomasi, 2015). Due to significant heterogeneity in case definitions, peri-implantitis prevalence in the included individual studies varied between 1% and 47%. Treatment of peri-implantitis is difficult and complex. The surface structure and implant threads make assessing and removing the biofilm and hard deposits difficult.
