Comparative Assessment of Salivary Endothelin-1 Levels In Periodontitis Subjects Following Non-Surgical Periodontal Therapy (Nspt) With Adjunctive Photobiomodulation And Nspt Alone: A Prospective Interventional Study

N\AAbstract
Lumbar interbody fusion for degenerative spondylolisthesis usually entails sacrificing one or both of the facet joints when approached posteriorly. The ‘facet preserving’ PLIF described by Cloward carries an advantage of preserving bone stock, compared to the most widely used Transforaminal Lumbar Interbody Fusion technique.
Aim: To Compare Posterior Lumbar Interbody Fusion and Transforaminal Lumbar Interbody Fusion techniques.
Settings and Design: Cohort study.
Methods and Material: We compared the complications, clinical and radiological outcomes of PLIF (n = 25) and TLIF (n = 50). Outcome measures included Oswestry Disability Index (ODI) , modified Japanese Orthopaedic Association score (mJOA), and visual analog score (VAS). Radiographs were repeated at six months. Peri-operative outcomes like blood loss (ml), operative time (minutes), length of stay in hospital (days), incidence of surgical complications were also recorded.
Statistical analysis: t-test was used for the analysis of continuous data with normal distribution and Mann-Whitney U-test for data with non-normal distribution. Chi-square test was performed for categorical variables with groups. Pearson correlation done between two continuous variables. Differences were considered significant at P<0.05.
Results:Average follow up time for Posterior Lumbar Interbody Fusion technique was 28 months compared to 25 months for Transforaminal Lumbar Interbody Fusion technique (P value 0.52). Operative time was significantly lower in Posterior Lumbar Interbody Fusion technique (P value < 0.001). Complication rate (P value 0.132), clinical and radiological outcomes were comparable in both the techniques.
Conclusions:Both Posterior Lumbar Interbody Fusion and Transforaminal Lumbar Interbody Fusion technique yield
