Identification of Bacteroides forsythus in subgingival dental plaque with the aid of a rapid PCR method.

abstract：:Estrogen deficiency results in disruption of maxillary alveolar bone microarchitecture. Most of the actions of estrogen in long bones occur via estrogen receptor α (ERα). However, the function of ERα in the maxillary bone has not been defined. We aimed to investigate the role and underlying mechanisms of ERα in the ph...
