- چکیده انگلیسی: BACKGROUND AND AIM: An important goal of periodontal plastic surgery is the creation of attached gingiva around the teeth. In this study, the aims were to culture gingival fibroblasts in a biodegradable scaffold and measure the width of attached gingiva after the clinical procedure.METHODS: This study was carried out on 4 patients (8 sites), with inadequate attached gingiva next to at least two teeth in contralateral quadrants of the same jaw. A biopsy of attached gingiva (epithelial + connective tissue) was taken using a surgical blade. Following culture of gingival fibroblasts, 250 × 103 cells in 250 µl nutritional medium were mixed with platelet-rich in growth factor (PRGF). Periosteal fenestration technique was done on one side (control) and tissue-engineered mucosal graft (test) was carried out on the contralateral side in each patient. The width of keratinized tissue, probing depth (PD) and width of attached gingiva were recorded at baseline and 3 months after the operation.RESULTS: An increased width of keratinized and attached tissue on all operated sites after 3 months was observed. These results showed the increased mean of the width of keratinized and attached gingiva to be 4.17 mm and 4.14 mm in test and 1.10 mm and 1.10 mm in control sites, respectively. The difference of keratinized and attached gingiva width between test and control sites was significant (P = 0.030, and P = 0.010 respectively).CONCLUSION: According to the results of this study, PRGF can be used as a scaffold to transfer gingival fibroblasts to recipient sites with significant clinical results.

- چکیده:
- چکیده انگلیسی: Statement of the Problem: Ultra-soft bristles are recommended for individuals with gingival recession, dentinal hypersensitivity and patients who have undergone periodontal surgeries. However, comparative effectiveness of ultra-soft toothbrushes on dental plaque and bleeding indices has not extensively been studied, and a consensus has yet to be reached on their efficacy.
Purpose: The aim of this study was to investigate the effect of ultra-soft toothbrushes with different commercial brands on plaque and bleeding indices.
Materials and Method: In this cross-over randomized clinical trial, 30 participants were selected using convenience sampling method. The subjects were randomly divided into three groups (n=10). In the first session, the bleeding index was recorded. Then each subject was given a toothbrush (Oral B, GUM, or Fuchs), asked to brush at least twice a day using the Bass technique, then avoid brushing for 24 hours after a week and refer for recording the indices. During the second session, bleeding on probing was recorded before brushing, and plaque indices were recorded before and after brushing. Plaque indices before brushing were considered the baseline plaque indices. After one week of wash-out, each subject used the next toothbrush in terms of the group involved. Turesky plaque index, O’Leary plaque index and bleeding index were evaluated. The distribution of data was normal. Therefore, ANOVA, t-test, and post hoc tests were used for the analysis of data.
Results: The bleeding and plaque indices decreased significantly compared to the baseline with the use of all the three ultra-soft toothbrushes evaluated (p < 0.05), with no significant differences between the three brands (p > 0.05) except for the superiority of Fuchs toothbrush in decreasing the Turesky plaque index.
Conclusion: Ultra-soft toothbrushes can reduce plaque index compared to the baseline, but they do not decrease the plaque index up to the optimal level, which might affect their prescription.- انتشار مقاله: 24-07-1398
