Dental erosion is the chemical loss of dental hard substances caused by exposure to acids not derived from oral bacteria. Mechanical forces from, for example, the tongue, the cheeks or toothbrushing, increase loss of partly-demineralized tooth surfaces and the cumulative loss of dental hard tissue is defined as erosive tooth wear (ETW). Dental hard tissue losses which occur because of very frequent acid exposure, such as through increased vomiting, but without mechanical stress, are also assigned to tooth erosion. Without prior softening, practically no loss of enamel takes place due to abrasion with the modern Western diet. The present work is a continuation of earlier work. A total of 226 beverages, food, stimulants as well as medicines and mouthwashes were tested for their erosive potential on premolars and deciduous molars covered with a human pellicle. The influence of temperature, phosphate and calcium was also investigated in additional experiments. The change in hardness before and after immersion in the respective test substance was measured and the erosive potential was classified. For each test product, we determined pH and other properties which were possibly related to erosive potential. There were considerable and sometimes surprising differences between the tested products. The addition of phosphate did not influence the erosive potential of the liquids, but calcium did. A modified erosion scheme is presented, which incorporates these and other new findings.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"133 7-8","pages":"440-455"},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10109245","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}

The implant surfaces were painted to be visually distinguishable and debrided with ultrasonic instruments (US) and an air powder waterjet device (AIR). Uncleaned implants served as positive controls. After the standardized cleaning, the implants were photographed and divided into three zones (upper marginal shoulder zone (A); lower marginal shoulder zone (B); fully threaded sub-shoulder zone (C)), and analyzed with an image processing software. On test implants, AIR was almost 100% efficacious compared to 80-90% with US, in both upper zones (A/B). In control implants, results of both AIR and US were almost 100% in zone A, but only 55-75% in zone B. In both implants, AIR showed statistically significant higher efficacy than US (P<0.05).

In this study, a presurgical implant decision in a case of SAPHO (synovitis, acne, palmoplantar pustulosis, hyperostosis, osteitis) is described. Since the etiology of this syndrome is likely to involve genetic, infectious and immunological components, lipopolysaccharides (LPS) may conceptually trigger cytokine production leading to a specific chronic inflammation and immunological host response. This may hamper proper healing or accentuate the destruction of periodontal host tissues. In our approach, we examined the ex vivo cell viability and immune responses of primary osteoblasts and keratinocytes under sterile inflammation induced by P. gingivalis LPS. Keratinocytes and osteoblasts were obtained from biopsies of the keratinized gingiva and alveolar bone tissues of a SAPHO human subject. Enzymatically dissociated cells were thus cultured and incubated to LPS at different concentrations (50ng/ml, 200ng/ml, 500ng/ml and 1μg/ml) for 24 h in order to test inflammatory cytokine response (quantitative real time PCR) and toxicity (cell viability). Healthy primary keratinocytes and osteoblasts were used as control cells. The highest concentration of LPS (1μg/ml) significantly reduced cell viability (p < 0.05). Meanwhile, all tested LPS concentrations similarly enhanced the mRNA expressions of selected inflammatory cytokines (TNFα, IL-6, IL-8, IL-1β and IL-1𝛼) up to ≈3.5-fold, when compared to the healthy cell controls (p < 0.05). This study demonstrated a valuable inflammatory risk evaluation before implant placement, which was successfully performed based on the presented laboratory diagnostic/prognostic approach.Sapho.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"133 5","pages":"297-303"},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9482246","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}

Furthermore, they can be used to objectively rate and compare the ability of health care providers to meet the needs of their patients. In patients with advanced resectable oral squamous cell carcinoma, optimal surgical treatment of the neck and timely initiation of both surgical and adjuvant therapy, when indicated, are crucial for recurrence-free and overall survival. This retrospective analysis included 160 patients who received primary resection of oral squamous cell carcinoma and concurrent neck dissection. It aimed to investigate how well quality metrics were met during a 6-year period in the department of oral and maxillofacial surgery at a university hospital. 93.1% of patients were seen in the specialist's office within 21 days after referral. Resection was classified as R0 in 94.4%. A lymph node yield ≥ 18 was achieved in 82.5%. The lymph node ratio was ≤6% in 43.3% of nodal-positive necks. Readmission and unplanned revision surgery were rare (6.9%). Adjuvant radiotherapy was started ≤ 6 weeks after surgery in 45.3%, and the indication was in accordance with international guidelines in all cases. \u0000Quality metrics are an effective tool for planning process optimization in a hospital. Moreover, nodal quality metrics such as lymph node yield and lymph node ratio could, after validation, complement existing and well-established prognostic parameters for patient-specific adaptation of adjuvant treatment plans.","PeriodicalId":38153,"journal":{"name":"Swiss dental journal","volume":"133 4","pages":"230-235"},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9166507","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}
