Abstract

Impacts of autonomous truck’s passes on pavement have been analyzed in this research. Two types of lateral positioning namely zero wander and uniform wander along with a super single wide tire and a dual tire have been analyzed with variable traffic speeds in ABQUS. The study concludes with the results in favor of usage of a super single wide tire under a uniform wander mode. The highest amount of pavement damage in terms of maximum rut depth is caused by the dual wheel assembly moving under a zero-wander mode. The magnitude of rut depth increases by a factor of two when a dual tire assembly is used instead of a wide tire assembly. At a uniform wander mode, rut depth increases by 0.2 mm for every 10 km/h decrease in traffic speed within 90 km/h to 70 km/h range.

Objective

The aim of the present short-term follow-up study was to assess the effect of scaling and root planing (SRP) with and without adjunct use of an essential-oil-based mouthwash (EOBM) on whole salivary interleukin (IL)-1beta (β) levels in patients with periodontal disease.

Methods

Ninety individuals with periodontal disease were divided into two groups. Patients in group 1 underwent SRP and were instructed to rinse with 10 mL of an EOBM twice daily for 30 days. Patients in group 2 underwent SRP and were instructed to rinse with 10 mL of water twice daily for 30 days. Whole saliva samples were collected, and IL-1β levels were measured at baseline and after 60 days of treatment. P-values < 0.05 were considered statistically significant.

Results

At baseline, whole salivary IL-1β levels were comparable among patients in groups 1 (135.6 ± 13.5 μg/mL) and 2 (141.2 ± 5.4 μg/mL). After 60 days of follow-up, there is a significant decrease in whole salivary IL-1β levels among patients in group 1 (10.2 ± 6.4 μg/mL) as compared to those in group 2 (56.6 ± 10.2 μg/mL) (P < 0.01).

Conclusion

SRP, when performed with adjunct use of an EOBM, is more effective in reducing whole salivary IL-1β levels as compared to when SRP is performed without the use of an EOBM.
