Biochemical and X-ray micro-computed tomographic analyses of critical size bone defects grafted with autogenous bone and mercerized bacterial cellulose membranes salified with alendronate.

Objectives: This study aimed to evaluate the repair of critical-sized bone defects grafted with autogenous bone and mercerized bacterial cellulose membranes (BCm) salified with alendronate (ALN).

Methods: Forty-eight male Wistar rats underwent surgery to create a 5 mm-diameter bone defect in the calvarium. The removed bone was particularized, regrafted into the defect, and covered by a BCm according to the group: control group (CG), simply mercerized BCm; group 1 (G1), negatively charged BCm (BCm-CM) salified with ALN; and group 2 (G2), positively charged BCm (BCm-DEAE) salified with ALN.

Salivary pH and oral health of Brazilian para-athletes: Saliva and oral health of para-athletes.

Aims: This study aimed to investigate the association of the salivary pH and parameters of oral health in Brazilian para-athletes.

Methods And Results: The sample was composed of 271 Brazilian para-athletes (147 athletics, 61 powerlifting, and 63 swimming); mean age was 31.2 ± 11.
