Antimicrobial effects of agitational irrigation on single- and multispecies biofilms in dentin canals
In conclusion, EDDY was as effective as PUI when combined with NaOCl. However, the apical portion, which had a low antimicrobial efficiency, remains a concern. Mechanical instrumentation is incapable of completely eradicating bacteria, and additional research is required to improve the eff icacy of root canal disinfection. (Source: Odontology)

Cav1.2 regulated odontogenic differentiation of NG2+ pericytes during pulp injury
AbstractNG2+ pericytes, as the possible precursor cells of mesenchymal stem cells (MSCs), have drawn attention due to their ability to differentiate into odontoblasts. Cav1.2 is involved in the differentiation process of stem cells, but its role in the differentiation of NG2+ pericytes is not clear. The aim of the present study was to examine the role of Cav1.2 in the differentiation of NG2+ pericytes into odontoblasts. NG2+ pericytes were obtained from human dental pulp cells by magnetic-activated cell sorting. During the odontogenic differentiation of NG2+ pericytes, the effects of the Cav1.2 inhibitors, nimodipine and C...

Masticatory path pattern and masticatory performance while chewing gummy jelly
AbstractThe purpose of this study was to clarify masticatory path pattern and masticatory performance during gummy jelly chewing. A total of 235 healthy adults were asked to chew gummy jelly for 20 s on each side, and the masticatory movement was recorded using a Motion Visi-Trainer (MVT V1). Next, the amount of glucose extraction was measured as a parameter of masticatory performance. The masticatory path was classified into one of five patterns newly devised: normal pattern (N, opening: st raight or concave, closing: convex) and abnormal patterns (A1–A4). The number of occurrences of each pattern was investigated and...

Distribution of periodontopathic bacterial species between saliva and tonsils
AbstractPeriodontopathic bacteria cause an inflammatory disease localized in the periodontal tissue and are associated with various conditions in other body parts. The distribution of periodontopathic bacterial species in the tonsils is unknown, even though the tonsils are located close to the oral cavity, and inflammation of the tonsils causes various systemic diseases. We detected the major periodontopathic bacterial species residing in saliva and tonsil specimens from 25 subjects undergoing tonsillectomy. Nine of the ten major periodontopathic bacterial species were detected by polymerase chain reaction of tonsil specim...
