Influence of risedronate on orthodontic tooth movement in rodents: a systematic review and case report.

Introduction: Bisphosphonates have an inhibitory impact on osteoclastic activity, reducing bone resorption. However, the influence of risedronate on tooth movement is not well-defined.

Objective: This systematic review assessed the effect of risedronate intake on orthodontic tooth movement.

Estrogen protects dental roots from orthodontic-induced inflammatory resorption.

Objective: Root resorption is a side effect of orthodontic tooth movement (OTM). Despite the recognized role of estrogen on bone, there is little information about their effects on orthodontic-induced inflammatory root resorption (OIIRR). We aimed to investigate if estrogen deficiency affects OIIRR in two mice strains.

Prolactin regulates kisspeptin neurons in the arcuate nucleus to suppress LH secretion in female rats.

Prolactin (PRL) is known to suppress LH secretion. Kisspeptin neurons regulate LH secretion and express PRL receptors. We investigated whether PRL acts on kisspeptin neurons to suppress LH secretion in lactating (Lac) and virgin rats.
