Article Synopsis
- Red complex bacteria are highly virulent in periodontal disease, and this study focused on their relationships with other oral bacteria in older Japanese individuals.
- Polymerase chain reaction was used to analyze dental plaque from 116 subjects, finding that individuals positive for red complex bacteria had significantly higher detection rates of certain periodontal pathogens compared to those who were negative.
- The findings indicate that individuals harboring all three red complex species have a unique oral microbiome, showcasing greater α-diversity and lower β-diversity, suggesting they may be more prone to developing periodontal disease.
Article Synopsis
- The culture filtrate extract of the golden bootleg mushroom showed strong antifungal effects, leading to the isolation of two new sesquiterpenoid compounds, with respective molecular weights of 234 and 259.
- Mass spectrometry confirmed these compounds, named phaeolep aldehydes A and B, featured an aldehyde group, with phaeolep aldehyde B also having a cyanohydrin group.
- Phaeolep aldehyde A inhibited the growth of several fungi at a dosage of 10 ppm, while phaeolep aldehyde B showed even stronger activity, reducing spore germination of one fungal species by 58.2% at just 0.25 ppm.
Purpose: This study aimed to evaluate the reliability and validity of a four-item questionnaire using a face rating scale to measure dental trait anxiety (DTA), dental trait fear (DTF), dental state anxiety (DSA), and dental state fear (DSF).
Materials And Methods: Participants were consecutively selected from patients undergoing scaling (S-group; n = 47) and implant placement (I-group; n = 25). The S-group completed the questionnaire both before initial and second scaling, whereas the I-group responded on the pre-surgery day (Pre-day), the day of implant placement (Imp-day), and the day of suture removal (Post-day).
Article Synopsis
- This report discusses the replacement of fixed implant-supported prostheses (FIP) with implant overdentures (IOD) in an older Parkinson's disease patient to enhance oral hygiene and manage mucosal health.
- The patient struggled with various health issues, including hospitalization for cholecystitis and aspiration pneumonia, which complicated ongoing dental care and maintenance of the IOD.
- Despite efforts to manage the patient's condition and provide regular oral cleaning, complications like mucosal ulcers and peri-implantitis persisted, ultimately leading to inadequate care and hospital readmission.
Purpose: This prospective cohort study examined the effects of the number of present and functional teeth on mortality among older Japanese adults requiring nursing care in an environment of comprehensive oral hygiene and nutritional management.
Methods: The study included 174 older adults (mean age: 84.4 ± 8.
