Specimens were submitted to thermal cycling, chemical aging or water storage. Bond strength was evaluated by testing machine; fracture pattern observed by optical microscopy, and degree of conversion evaluated in micro-Raman spectrophotometer. Data were analyzed by two-way ANOVA and Tukey's test (α=0.05). \u0000\u0000\u0000Results: G1 showed greatest bond strength (p<0.001) followed by the G2 with higher values compared to G3 and G4, and no difference between them. For G2, G3 and G4, the thermal cycling affected the bond strength. The greatest degree of conversion was for G2 with Single Bond Universal, significantly higher than Scotchbond and RelyX U200. G4 provided highest value for the cement layer, and statistically higher than G1. G1 showed the highest strength than G3 associated to resin cement or self-adhesive resin cement. Different fracture patterns were observed.\u0000\u0000\u0000Conclusions: Aging methods reduced the bond strength. Degree of conversion was highest in the adhesive layer photo activated and in the cement layer with dual activation.

It accounts for 3% of all head and neck tumours and 70-80% of benign salivary gland tumours. The clinical features depend on the size, location and in some cases the potential to undergo malignant transformation. They are usually solitary, unilateral, firm and mobile, painless and slow growing, hence the long duration before presentation for treatment. \u0000Purpose: To present an 84-year-old female who first presented 16 years ago with a 4-year history of bilateral swellings at the left and right parotid regions, measuring 8.0 cm by 10.0 cm and 3.0 cm by 5.0 cm respectively. Due to fear of surgery, the patient gave consent for the excision of only the left lesion whose histology report came out to be pleomorphic adenoma. The right swelling was left in-situ. The time lapse of 16years resulted in gradual increase in size of the right lesion now measuring 12.0 cm by 8.0 cm with no clinical symptoms but aesthetically unpleasant to patient. With consent, the right lesion was excised and pathological examination showed a benign lesion composed of ovoid and spindle-shaped epithelial cells arranged in sheets and ducts, some of which contain eosinophilia coagulum and cystic degeneration in other foci. No evidence of malignancy. No post-operative recurrence on the left side16 years after and on the right side 24 months after treatment \u0000Conclusion: Pleomorphic adenoma can grow to enormous size, and with a potential to undergo cystic degeneration if left untreated. Early presentation for treatment is of high importance to prevent complications associated with delay.","PeriodicalId":197045,"journal":{"name":"European Journal of Dental and Oral Health","volume":"124 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129628714","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}

Biopsy is the most common tool used for the diagnosis. Its treatment is usually surgical excision and lately the use of lasers for its excision has emerged.

Patients undergoing various dental procedures were enrolled after written and verbal informed consent. Risk Stratification of each procedure was done applying novel risk assessment scoring system, according to the level of risk contact with saliva was given score 1, contact with blood scored as 2, production of aerosol (low level) through triple syringe was given score 3, high aerosol production by ultrasonic piezoelectric instruments was scored as 4. If the complete duration of the dental procedure was >60 min score assigned was 0.75, for procedures with 30 to 60 mins duration score specified was 0.50, if the duration of the procedure was less than 30 min score for that procedure was 0.25. For each patient total score of all these parameters was accumulated to grade risk of SARS -CoV-2 transmission as low (score <4), medium (score 4 to 6), or high (score >6) depending upon the accumulative score of each procedure. \u0000Results: Nine hundred and fifteen patients with a gender distribution of 163 (17.9%) males and 748 (82.1%) females with an age range < 18 – 45 years undergoing the dental procedure were enrolled.

Out of 174 maxillofacial procedures, only 18 (10.3%) were of high risk, similarly out of 113 orthodontics procedures, only 1 (0.9%) was of high risk and for 147 prosthodontic procedures, there were 55 (37.4%) high-risk procedures. On the other hand, for operative dentistry procedures (n=181), majority of 128 (70.7%) posed a high risk, among pediatrics procedures (n=92) there were 62 (67.4%) high-risk procedures and for periodontics (n=204) about 173 (84.8%) were of high-risk nature.
