Estimation of L-carnitine levels in diabetic completely edentulous patients for implant diagnosis: A cross-sectional study

Background

Carnitine is effective in preventing the accumulation of end products related to lipid peroxidation due to its anti-inflammatory and antioxidant effects. Carnitine also exerts a significant anti-inflammatory role through the downregulation of the nuclear factor kappa beta pathway, which leads to a decrease in the expression of pro-inflammatory cytokines.The aim of the study was to estimate the L-carnitine (L-C) levels in diabetic completely edentulous patients.

Materials and Methods

A cross-sectional study was conducted after the selection of 60 samples based on the inclusion and exclusion criteria. The collected saliva samples were utilized to measure the levels of L-C using the sandwich enzyme-linked immunosorbent assay (ELISA) method. One hundred microliters of sample was applied to a particular row of wells and incubated for an hour as part of the sandwich ELISA procedure. After the wells had been cleaned, a second batch of monoclonal L-C was added, and they were once more incubated for an hour. The horseradish peroxidase substrate was then applied after washing the second batch as well. To allow the blue-to-yellow color transition, the wells were kept steady. Following the observation of the color shift, the OD was measured, and the concentration was determined using the sandwich ELISA kit's standard curve as an intercept. The data were statistically analyzed using the independent t-test (significant level P < 0.05) and were tabulated.

Results

The L-C levels have higher levels in nondiabetic patients than in diabetic patients. The difference in the baseline mean value between the groups was statistically significant (P = 0.00). Although it is statistically significant (P = 0.00), the mean value for diabetic individuals is 0.19 as opposed to 0.29 for nondiabetic patients.

Conclusion

Based on the findings, it can be concluded that L-C improves insulin sensitivity and glucose disposal in diabetic completely edentulous patients.

Soft tissue re-growth after different crown lengthening techniques among Indian patients

Patients often report complaining of fractured or decayed teeth with severe morphological deformities. However, all these clinical scenarios require the same level of care and consideration to rehabilitate form, function and esthetics. Some cases have sufficient clinical crown height while others often require an interdisciplinary approach in the form of orthodontic/surgical extrusion or surgical periodontal options. A common factor delaying treatment is soft tissue regrowth after crown lengthening which delays the impression required for final prosthesis. Therefore, it is of interest to compare the prevalence of soft tissue regrowth a week after different crown lengthening techniques including laser gingivectomy, electrocautery gingivectomy, modified Widman flap and apically repositioned. The parameters assessed included 1-week postoperative soft tissue regrowth after crown lengthening, age of patients and gender. It was observed that laser and electrocautery-assisted gingivectomy had a higher rate of soft tissue regrowth as compared to surgical techniques. It was further noted that laser and electrocautery assisted gingivectomy had a higher frequency of soft tissue rebound growth compared to surgical crown lengthening using modified widman flap and apically repositioned flap, which was statistically insignificant. Patients within the age groups of 26-60 years were found to have a higher tendency of soft tissue regrowth, which was found to be clinically and statistically significant (p<0.05).

Effectiveness of Chitosan Nanohydrogel as a Bone Regenerative Material in Intrabony Defects in Patients With Chronic Periodontitis: A Randomized Clinical Trial

Aim:

Different procedures have been attempted to regenerate intrabony defects in periodontitis but complete regeneration is still a herculean feat. Nanoparticles could prove to be advantageous because of their small size and increased surface area. The aim was to evaluate the effectiveness of a chitosan nanohydrogel as a periodontal regenerative material in the management of intrabony defects.

Materials and Methods:

Twenty patients within the age group of 30 to 60 years with intrabony defects >3 mm and clinical attachment levels >5 mm were selected. They were divided randomly into two groups: group-1, which received only open flap debridement with bone graft and acted as control, and group-2, which received open flap debridement, bone graft mixed with a chitosan nanohydrogel, and acted as the test site. Clinical and radiographic measurements were recorded at baseline, three months, and six months. Intragroup comparison was done using a paired t-test and intergroup comparison was done using an unpaired t-test with the statistical value set at P < .05.

Results:

Chitosan hydrogel incorporated bone grafts showed improved bone regenerative potential. The mean reduction in clinical attachment level in group-2 (8.7 ± 0.6 to 1.6 ± 0.8) was significantly higher than that of group-1 (8.6 ± 0.5 to 2.4 ± 0.7). The mean reduction in probing depths in group-2 (test group) was significantly higher (8.3 ± 0.9 to 1.6 ± 0.8) when compared to group-1 (8 ± 0.8 to 2.3 ± 0.7). Significant amount of defect fill was obtained in both the groups from baseline to six-month period.

Conclusion:

Organic materials such as chitosan could have potential bone regenerative capacity.

Views on antioxidant mouthwashes as adjunct in periodontal therapy

Clinical decision is often difficult with chlorhexidine mouthwash. The use of antioxidant mouthwashes for the treatment of periodontal disease is in practise. Therefore, it is of interest to collect gleaned information on Antioxidant mouthwashes as periodontal therapy from known literature. Improvement in treatment using antioxidant mouthwashes is reported in several studies. The mouthwash with antioxidants has similar anti-gingivitis, antiplaque and antimicrobial effects as that of chlorhexidine mouthwash.
