Ectopic wisdom teeth are a rare occurrence. Furthermore, it is highly unusual to see lower wisdom teeth in the ascending ramus of the mandible. This case report is about a 41-yearold male patient with right sided facial swelling. Presenting initially as suspected right sided parotitis, the source of the infection was quickly identified as an ectopic wisdom tooth located in the ramus of the mandible. This report describes the associated investigations, management (pre-, peri-and post-) and appropriate follow-up after discharge, for a symptomatic, ectopically placed third molar tooth. The current UK guidelines for wisdom teeth removal is published by NICE (National Institute of Clinical Excellence). In conclusion, the case highlights the importance of thorough investigation and possible amendment of current guidelines.
Background:The evidence of the anti-caries effect of arginine toothpaste has been questioned and randomised trials independent of commercial interests have been required. Aim:To examine, in relation to caries, the pH response in interproximal plaque in situ to an acidic challenge and the pH and buffer capacity of stimulated saliva following a six-week period of using a toothpaste containing 1.5% arginine/1450 ppm fluoride or no arginine/1450 ppm fluoride.Methods: Thirty-three healthy adults with no visible caries lesions or ≥ 1 current manifest lesion participated in the study. Acid plaque responses were examined by interproximal pH-measurements using pH-indicator strips. Two weeks after professional cleaning, pH-measurements were performed before and up to 15-min after a 1-min rinse with 10 ml of a 10% sucrose solution. This procedure was repeated after a 6-week test period of using randomly selected toothpaste with arginine and fluoride or with fluoride alone. The stimulated salivary-pH and buffer capacity were also measured. Results:In the caries group, the use of toothpaste with arginine and fluoride resulted in increased pH-values in the four sites tested. No statistically significant increased plaque pH-values were found in the no-caries group. In addition, saliva buffer capacity and pH was increased in the caries group. Conclusion:Using fluoride toothpaste with 1.5% arginine affects the oral environment positively in adults with caries, in the form of increased supragingival plaque pH and increased salivary pH and buffer capacity.
Objective: To examine the pH response to an acidic challenge in site-specific plaque following a six-week period of using toothpaste consisting of 1.5% arginine and 1450 ppm fluoride or just using 1450 ppm fluoride toothpaste alone, in relation to caries. Methods: Thirty-three healthy adults with no caries (caries-free) or ≥1 current manifest lesion (caries) participated in the study. Interproximal plaque-pH was measured in four sites. Two-weeks after professional cleaning, pH-measurements were performed before and up to 15-min after a 1-min rinse with 10 ml of a 10% sucrose solution. This procedure was repeated after a 6-week test period of using randomly selected toothpaste with 1.5% arginine and fluoride or with fluoride alone. The stimulated salivary flow rate was determined and the salivary-pH and buffer capacity was measured. Results: In the caries group, the use of toothpaste with arginine and fluoride resulted in increased pH-values in the four sites tested. Although it was not statistically significant, increased pH-values were found in the caries-free group. In addition, the whole saliva buffer capacity and pH was increased in the caries group. Conclusion: The most pronounced effect on plaque-pH and stimulated saliva after using arginine and fluoride toothpaste was seen in the caries group.
