Through the OfD
, the Scandinavian country offers assistance to developing countries to achieve poverty reduction through responsible management of petroleum resources.
The mean ages were of 28.4 years in the FD group (n=14) and 27.3 years in the OFD group (n=21).
We considered as OFD the presence of vocal nodules, polyps, edema, and thickening of the vocal folds, and as FD the minimal structural alteration of the coverage, glottic clefts, and incorrect vocal habits.
Considering MPT /e/, we found a mean of 12.1 s for the FD group and 10.7 s for the OFD group.
The experimental groups (1-wall [ABB + CM] and 3-wall [ABB + CM]) showed significantly higher NBV values [Figure 3]e as compared to that in the OFD groups (1-wall [OFD] and 3-wall [OFD]) ( P < 0.05), respectively.
One-wall intrabony defect: A significantly large amount of new cementum, new periodontal ligament, and new bone was observed in the ABB + CM sites as compared to that in the OFD sites [Figure 4] and [Figure 5].
The intrabony defects were mostly occupied by lamellar bone and woven bone, and the height of newly formed bone was more than that in the OFD group.
