Purpose: The purpose of studies on antibiotics used topically on the root surface of avulsed teeth is to evaluate their antiresorptive properties which favor the repair of the periodontal ligament and the reestablishment of the dentoalveolar articulation. The aim of the present study was to determine the effect of lincomycin treatment of the root surface on tooth replantation. Methods: Ten rats were distributed into two groups (I - control; II - experimental). The right maxillary incisor of the animals was extracted and stored in milk for 30 min. The tooth in group I was rinsed with normal saline and replanted; in group II, the incisor was immersed in lincomycin for 5 min before replantation. The animals were euthanized on the 21st day postoperative. The right hemimaxilla was submitted to histological sectioning and stained with H&E for microscopic evaluation. Results: Group I: the periodontal ligament appeared dispersed, with moderate to intense lymphoplasmacytic infiltrate, and dentoalveolar articulation was not reestablished. Group II: complete repair of the ligament was evident, and there were few inflammatory cells and small areas of inflammatory resorption and ankylosis. Conclusion: The use of lincomycin allowed the repair of the periodontal ligament and reduced inflammation. There were still areas of inflammatory resorption and ankylosis. [ABSTRACT FROM AUTHOR]

Purpose: This paper reports the assessment of nutritional anthropometric parameters of three patients who were submitted to orthognathic surgery followed by intermaxillary fixation and liquid diet. Case description: This prospective case series describes the changes in nutritional parameters of three adult subjects aged 20 to 24 years, including one male and two females, who received elective orthognathic surgery followed by intermaxillary fixation with orthodontic elastics for 14 days. The hospitalized patients were instructed to go on a liquid diet with hypercaloric and hyperprotein intake. After discharge, the patients continued the liquid diet up to 28 days postoperatively. Data on weight loss, body mass index, triceps skinfold thickness, midarm circumference, and midarm muscle area were collected one week before surgery, one week after surgery, and four weeks after surgery. All three patients had severe weight loss (>2% weight loss per week). Conclusion: The interaction between nutritionist and oral surgeon is essential in order to plan an adequate dietary intervention after orthognathic surgery to minimize occasional weight loss.
