Cytological assessment of healing palatal donor site wounds and grafted gingival wounds after application of ozonated oil: an eighteen-month randomized controlled clinical trial.

OBJECTIVE: The present study was undertaken to assess the therapeutic effects of topical ozonated oil on early healing of free gingival graft surgical sites. STUDY DESIGN: Twenty subjects were entered into this triple-blinded, randomized, placebo-controlled clinical trial, designed to evaluate the efficacy of ozonated oil on free gingival graft surgical wounds. Subjects were assigned to either the ozone group, in which ozonated oil was applied to the surgical wound, or the control group, in which non-ozonated oil was used as a control. Patients were postoperatively evaluated by cytological analysis. Cytological analysis consisted of the keratinisation and superficial cell indices measured at baseline, after 24 h, on the 3rd, 7th, 14th and 21st day and 2, 3, 8 and 18 months postoperatively. RESULTS: Cytological results showed that there was a significant (p < 0.001) improvement in epithelial healing by the 7th, 14th and 21st day and 2, 3 and 8 months postoperatively in the ozone group compared to the control group. CONCLUSION: The present study showed significant improvement in epithelial healing and gingival health after topical application of ozone-treated plant oil to gingival surgical sites.

The management of a persistent periapical lesion caused by an apicomarginal defect, associated with a root end fracture in an endodontically treated tooth: a clinical report.

This is a case report of the presentation and the management of an apicomarginal defect which was associated with a root end fracture in an endodontically treated tooth. In spite of a successful Root Canal Treatment (RCT), if the fractured root end is left intact, considering inadverdent ankylosis or resorption, it may progress to the development of a bony dehiscence.

Clinical effect of miswak as an adjunct to tooth brushing on gingivitis.

BACKGROUND: The aim of the study was to clinically evaluate the effect of miswak as an adjunct to tooth brushing on plaque levels and gingival health in subjects diagnosed with mild to moderate chronic generalized marginal gingivitis in comparison with those of toothbrush users. MATERIALS AND METHODS: The study comprised of 30 systemically healthy subjects, aged 18-35 years diagnosed with mild to moderate gingivitis. The study was designed as a randomized, single-blind, parallel-armed study. Subjects were randomly divided into three groups. Group A (toothbrush users), group B (toothbrush and miswak users), and group C (miswak users). Subjects were advised to use toothbrush, miswak, or both, three times daily depending on their respective allocations. Gingival index according to Loe and Silness, Plaque index, according to Turesky modified Quigley-Hein plaque index, and the digital photographs of the total labial surfaces of the teeth were taken for image analysis. Recording of data were done at baseline, 2(nd), 4(th), 6(th), and 8(th) week time intervals. Obtained data were analyzed using repeated measure ANOVA and student t test (independent samples). RESULTS: Group B showed statistically significant (P<0.0001) decrease in plaque score and gingival score compared to group A and group C, respectively, from 2(nd) to 8(th) week, whereas no statistical significant difference was found in plaque score, when group A was compared with group C (P>0.05) from 2(nd) to 4(th) week. Further at the 6(th) and 8(th) week, there was significant difference (P<0.05) in plaque score between group A and group C. The difference in gingival score was not significant (P<0.05), when group A was compared with group C on all the indicated time intervals. CONCLUSION: Results showed significant improvement in plaque score and gingival health when miswak was used as an adjunct to tooth brushing.

Quantitative cytomorphometric analysis of exfoliated normal gingival cells.

BACKGROUND: The use of oral exfoliative cytology as a diagnostic aid accentuates the need for establishing an accurate baseline, thereby enabling the comparison of abnormal oral tissue with established baseline. AIMS AND OBJECTIVE: To detect any changes in the nuclear area (NA), cytoplasmic area (CA), and nuclear:cytoplasmic ratio (N:C ratio) values for clinically normal gingival smears in relation to age and sex of apparently healthy subjects. MATERIALS AND METHODS: Gingival smears were collected from 80 (40 male, 40 female) apparently healthy subjects belonging to the age group of 0-20, 21-40, 41-60, and more than 60 years. Smear slides were fixed by using spray fixative. The smears were stained using Papanicolaou procedure. The cytoplasmic and NAs were measured using image analysis software. Statistical analysis of the data was done using one-way ANOVA with Tukey-HSD procedure and Student's t test. RESULTS: The result showed that there was a significant difference (P<0.001) in NA, CA, and N:C in males of different age groups. There was a significant difference (P<0.001) in NA, CA, and N:C in females of different age groups. The difference in N:C between males and females was significant (P<0.001) in all the groups. The difference in NA, CA, and N:C with age irrespective of gender was significant (P<0.05). There was a significant difference (P<0.05) between males and females with respect to NA, CA, and N:C irrespective of age. CONCLUSION: Age-and sex-related alterations were observed in gingival smears, which could be a baseline for these variables to compare identical measurements, made on pathologic smears of oral premalignant and malignant lesions.

Therapeutic effect of topical ozonated oil on the epithelial healing of palatal wound sites: a planimetrical and cytological study.

AIM: To evaluate the effect of ozonated oil on palatal wounds. METHODS: Eighteen patients were randomized and allocated to either the ozone group (n = 8) or control (n = 10) group. Free gingival graft surgery was performed, and post-harvested palatal wounds were treated with either 2 mL ozonated oil or control oil daily for 1 week. A planimetrical analysis analyzed the digital image for the wound sizes and shape factor at baseline, at 24 h, and days 5, 7, 14, 21, and 28, postoperatively. A cytological analysis used the keratinization and superficial cell indices at baseline, 24 h, and days 3, 7, 14, and 21 and the second and third months, postoperatively. RESULTS: Planimetrical results showed a significant (P ≤ 0.05) improvement in wound size on days 5, 7, 14, 21, and 28, postoperatively, in the ozone group compared to the control group. Cytological results showed a significant (P ≤ 0.001) improvement in epithelial healing on days 7, 14, and 21, and the second and third months, postoperatively, after the application of ozonated oil compared to control oil. CONCLUSION: Our results showed significant improvement in wound size and epithelial healing after topical ozonated oil application compared to control oil on palatal wounds.

Correlation of periodontal status and bone mineral density in postmenopausal women: a digital radiographic and quantitative ultrasound study.

BACKGROUND: Data suggest that postmenopausal women with osteoporosis are at an increased risk for periodontal attachment loss and tooth loss; however, the extent of relationship between these two diseases is still not clear. AIM: The aim of the study was to evaluate the correlation of periodontal status and bone mineral density (BMD) in postmenopausal women. MATERIALS AND METHODS: The study population included 60 postmenopausal women aged 50-60 years (mean±SD: 55.5±3.4 years). Periodontal status was examined by plaque index, bleeding index, probing depth, and clinical attachment level (CAL). Digital panoramic radiograph was taken to measure the maxillary and mandibular alveolar bone density values. Skeletal (calcaneal) BMD was measured by quantitative ultrasound technique for T-score values. The recorded data for T-score, maxillary and mandibular alveolar bone densities, and periodontal status were subjected to statistical analysis for correlation and regression procedures. RESULTS: The results showed that mandibular alveolar (r=0.907, P<0.001) and maxillary alveolar bone density (r=0.898, P<0.001) had significant positive correlation with calcaneal T-score. Probing depth (r=-0.316, P<0.05), bleeding index (r=-0.277, P<0.05), and plaque index (r=-0.285, P<0.05) showed weak but significant negative correlation with calcaneal T-score and alveolar bone density of both the jaws, whereas CAL showed weak correlation with T-score which could not reach to a statistically significance level (r=-0.221, P>0.05). CONCLUSION: Calcaneal BMD was related to alveolar bone loss and, to a lesser extent, to clinical attachment loss, implicating postmenopausal bone loss as a risk indicator for periodontal disease in postmenopausal women.

The effect of periodontal therapy on the improvement of glycemic control in patients with type 2 diabetes mellitus: A randomized controlled clinical trial.

AIMS: The purpose of this study is to investigate the effect of improved periodontal health on glycemic control in type 2 diabetes mellitus (type 2 DM) patients who have generalized periodontitis. MATERIALS AND METHODS: A total of 45 type 2 DM patients with generalized periodontitis were selected for the study. The selected patients were randomly assigned to three groups (groups A, B, and C) comprising 15 patients each: * Group A received treatment with scaling and root planing only. * Group B received treatment with scaling and root planing followed by systemic doxycycline. * Group C received no treatment (control group). The periodontal parameters recorded included plaque index, gingival index, probing pocket depth, and clinical attachment level. These parameters were recorded at baseline (day zero), at 1 month, and at the end of 3 months. The following metabolic parameters were recorded: fasting blood glucose (FBG), postprandial blood glucose (PPBG), and glycated hemoglobin. These were recorded at baseline (day zero) and at the end of 3 months. STATISTICAL ANALYSIS: All the parameters were subjected to repeated-measures ANOVA and Scheffe's post hoc test. RESULTS: A statistically significant effect could be demonstrated for periodontal parameters for both group A and group B (treatment groups). Glycated hemoglobin values showed statistically significant decrease in treatment groups compared to the control group, with group B showing more significant decrease than group A. CONCLUSIONS: The results of this study showed that nonsurgical periodontal treatment is associated with improved glycemic control in type 2 DM patients.
