A Cone Bean Computer Tomography Investigation of the Newly Formed Mandibular Anterior Ridge following the Treatment of an Extended Comminuted Fracture: A 12-Year Follow-Up. Case Rep Dent 2024; 2024:1824016. [PMID: 38419613 PMCID: PMC10901576 DOI: 10.1155/2024/1824016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 08/11/2023] [Accepted: 01/27/2024] [Indexed: 03/02/2024] Open
Abstract
Introduction Extensive comminuted fractures are associated with tooth loss that ultimately leads to dimensional changes in the hard and soft tissues of the alveolar ridge. Reconstruction of the lost mandibular anterior ridge is very complex due to the natural curvature of the region. Case Presentation. In this case report, the combination of the modified shell technique with autologous bone plates and the guided bone regeneration (GBR) technique was performed on an 18-year-old patient after a comminuted fracture, to ensure new bone formation in the anterior ridge with a natural curvature. After the treatment progressed without complications, three dental implants were placed. Annual cone beam computed tomography (CBCT) images were obtained and evaluated using the GNU Image Manipulation Program (GIMP© 2.10). This allowed measurements of the buccal and lingual bone around the implants, showing the annual bone loss in a twelve-year observation period. Discussion. The treatment of the comminuted fracture and the combination of the modified shell technique with autologous bone plates, the GBR technique, and implant placement can be considered successful. The three dental implants were osseointegrated in 2010, with the buccal bone level averaging 1.31 mm below the implant shoulder and the lingual bone level 1.57 mm above the implant shoulder. In 2021, the measurements showed a bone loss of 0.99 mm at the buccal implant shoulder and 0.69 mm at the lingual implant shoulder. Conclusion The combination of the modified shell technique with autologous bone plates and the GBR technique is a reliable method to ensure new bone formation in the anterior ridge. The use of CBCT is an excellent method to evaluate bone resorption around dental implants, but due to minimal bone resorption in the observation period, an annual CBCT examination is exaggerated.

A split-face, blind, randomized placebo-controlled clinical trial investigating the efficacy and safety of hyaluronic acid filler for the correction of atrophic facial scars. J Cosmet Dermatol 2022; 21:3768-3778. [PMID: 35689521 PMCID: PMC9796717 DOI: 10.1111/jocd.15153] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Revised: 04/27/2022] [Accepted: 05/12/2022] [Indexed: 01/07/2023]
Abstract
BACKGROUND Hyaluronic acid fillers have been studied extensively for facial wrinkles; however, their efficacy for atrophic facial scars has yet to be analyzed in a prospective placebo-controlled study. OBJECTIVE To analyze the efficacy and safety of a hyaluronic acid filler for atrophic facial scars. METHODS & MATERIALS Fifteen subjects were randomized to receive up to 1 ml of VYC-17.5 L on one cheek and up to 1 ml of saline on the other side, with an optional touch-up treatment. Subjects were graded by a live blind evaluator using the Quantitative Global Scarring Grading System (QGSGS) (J Cosmet Dermatol. 2006;5:48), the Global Aesthetic Improvement Scale (GAIS), and Canfield photo-analysis. RESULTS According to the blind evaluator, there was a significant reduction 90 days after the last treatment on the QGSGS for VYC-17.5L compared with saline (-6.6 VYC-17.5L vs -1.7 saline [t(28) = -4.3196, p = 0.008]). There was a smaller, but still significant reduction on the QGSGS for saline alone (10.4 to 8.6 [t(14) = -3.453, p = 0.004]). In addition, 93% (13/14) of subjects chose VYC-17.5L over saline treatment and reported an improvement on the GAIS. There were no serious side effects and all minor side effects resolved by Day 30. CONCLUSION VYC-17.5L achieved significant improvements in rolling atrophic scars as compared to saline, though saline also had modest improvements.

TOXICS 2021; 9:toxics9120354. [PMID: 34941788 PMCID: PMC8708792 DOI: 10.3390/toxics9120354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Revised: 12/08/2021] [Accepted: 12/12/2021] [Indexed: 11/16/2022]
Abstract
Poly(ethylene glycol) diglycidyl ether (PEGDE) is widely used to cross-link polymers, particularly in the pharmaceutical and biomaterial sectors. However, the subcutaneous toxicity of PEGDE has not yet been assessed. PEGDE samples (500–40,000 μg/mouse) were subcutaneously injected into the paraspinal dorsum of BALB/c male mice. Cage-side observations were carried out with measurement of organ weight, body weight variation, and feed intake, as well as histopathological characterization on day 28 post-exposure. Mice that received 40,000 μg of PEGDE showed severe toxic response and had to be euthanized. Subcutaneous injection of PEGDE did not alter feed intake and organ weight; however, the body weight variation of mice injected with 20,000 μg of PEGDE was significantly lower than that of the other groups. Exposure to 10,000 and 20,000 μg of PEGDE induced epidermal ulcer formation and hair loss. The histology of skin tissue in mice administered with 20,000 μg of PEGDE showed re-epithelialized or unhealed wounds. However, the liver, spleen, and kidneys were histologically normal. Collectively, PEGDE, particularly above 10,000 μg/mouse, caused subcutaneous toxicity with ulceration, but no toxicity in the other organs. These results may indicate the optimal concentration of subcutaneously injected PEGDE.
