Background: Composite and Glass ionomer cement (GIC) are common restorative materials of non carious cervical lesions (NCCLs), which effects are controverisial. The aim of the present study was to compare the result of restorations on NCCLs between Composite and GIC. Materials and Methods: follow-up clinical trial with split-mouth design. Thirty-six patients with 96 NCCLs were divided into 2 groups (n=48/group): Group 1 restored by Composite, Group 2 restored by GIC. The restorations were evaluated at baseline, 1 and 3 months for pulpal sensitivity, restoration morphology and overall success grade. Results: GIC restorations gained 100% Good results for all parameters at 3 time points. Composite showed 87.5%, 93.8% and 97.9% Good results at baseline, 1 and 3 months, sequentially. At 3 weeks recall, 1 Composite restorations (2.1%) showed Moderate results of Retention and 2 Composite restorations (4.2%) changed colour. Conclusions: There was no statistically significant difference seen among the three groups for 3 parameters. Key words: non-carious cervical lesion, Composite, Glass ionomer cement
Objectives: Chronic periodontitis is the most common form of periodontal disease, greatly affecting the aesthetics, function as well as quality of life of patients. This study aims to evaluate the clinical features and the factor associated with chronic periodontitis. Materials and methods: This study was conducted on 60 patients with chronic periodontitis, who visited at Family Medical Center, Hue University of Medicine and Pharmacy, Hue University from April 2019 to October 2021. Periodontal parameters included: plaque index (PlI), gingival index (GI), periodontal probing depth (PPD), clinical attachment loss (CAL), and bleeding on probing (BOP). All statistical analysis was analyzed by SPSS version 26.0. Results: The rate of chronic periodontitis in women and man is 63.3%; 36.7%, distributed mainly in the age of over 55. The main visit reasons were loose teeth (45%), toothache (23.3%), and bleeding gums (20%). Most of the patients had severe periodontitis (88.3%). The patients who had poor oral hygiene habits showed a higher degree of periodontitis. Conclusion: Chronic periodontitis is a medical condition with an increasing incidence with age and is closely related to oral hygiene problems. Patients visit to the dental clinic when periodontitis has caused severe tissue destruction. Key words: chronic periodontitis, oral hygiene
Background: Recently, herbal therapy has become interested in research and application in dental treatment. Curcumin gel with extracts from Turmeric has also proven effective in periodontal treatment. The study aimed to evaluate the results of non-surgical periodontitis therapy with the help of topical curcumin gel. Materials and methods: Prospective, clinical intervention study on 30 periodontal pockets in 21 patients with mild and moderate periodontitis (AAP 2014). After the patients received scaling and root planing, curcumin gel was injected into periodontal pockets. The periodontal clinical indices were assessed at baseline and 30 days, 45 days after treatment. Results: All periodontal clinical indexes after 30 days and 45 days of treatment showed statistically significantly reduced compared to those at baseline (p<0.05). The decrease levels on the 30th day were higher than those on the 45th day. Conclusion: The results of non-surgical therapy of mild and moderate periodontitis with curcumin gel showed a significant improvement in periodontal clinical parameters. Key words: periodontitis, non-surgical therapy, curcumin gel
Background: The alveolar bone can be damaged by a variety of causes such as trauma, bone tumors and cysts, infection and tooth loss, affecting function, aesthetics, comfort and confidence of the patient. In order to reconstruct the alveolar bone defect, besides autologous bone, cellular and inorganic biological materials are being developed and widely applied including Biphasic Calcium Phosphate (BCP). Therefore, it is very essential to establish an animal model of alveolar bone defect to evaluate the progress of bone formation and the potential of materials before clinical application. Materials and Methods: The study was performed on 18 white, male, healthy rabbits weighing 2.5 ± 0.2 kg, 8-to-10-week aged, divided into 2 groups: group 1 (control), group 2 (BCP). The alveolar bone defect formation was performed in 2 groups, then reconstructed with BCP (group 2). Evaluation of soft tissue healing characteristics in 2 groups after 1, 3, 5, 7, 14 days after surgery and assessment of alveolar bone regeneration by X-ray and histological analysis after 2, 4, 6 weeks. Results: Healing score in each group increased gradually from day 1 to day 14, having statistical significance from day 5. Healing score of 2 groups tended to increase gradually in order: control group < BCP group (p > 0.05). X-ray scores in each group increased from week 2 to week 6, with statistical significance at week 6 (p < 0.05). X-ray scores of 2 groups tended to increase in order: the control group < BCP group (p > 0.05). New connective tissue formed in the control group reached the highest at week 4 and decreased after week 6 (p < 0.05). New bone formation in each group increased statistically from week 2 to week 6. The amount of newly formed bone in BCP group was significantly higher than in control group (p < 0.05). Conclusions: The above established model allows us to evaluate the capability of the bone regeneration of various materials. In addition, BCP is a potential material which can be used to reconstruct alveolar bone defects in patients
