Association replication studies have a poor track record and, even when successful, often claim association with different markers, alleles, and phenotypes than those reported in the primary study. It is unknown whether these outcomes reflect genuine associations or false-positive results. A greater understanding of th... |
OBJECTIVE |
The purpose of this prospective, randomized, double-blind study was to determine the effect of penicillin on pain in untreated teeth diagnosed with irreversible pulpitis. |
STUDY DESIGN |
Forty emergency patients participated, and each had a clinical diagnosis of an irreversible pulpitis. Patients randomly received a 7-day oral dose (28 capsules, 500 mg each, to be taken every 6 hours) of either penicillin or a placebo control in a double-blind manner. No endodontic treatment was performed. Each patient... |
RESULTS |
The administration of penicillin did not significantly (P >.05) reduce pain, percussion pain, or the number of analgesic medications taken by patients with untreated irreversible pulpitis. The majority of patients with untreated irreversible pulpitis had significant pain and required analgesics to manage this pain. |
CONCLUSION |
Penicillin should not be prescribed for untreated irreversible pulpitis because penicillin is ineffective for pain relief.Increase trend of social hymenoptera (wasps and honeybees) in urban areas, inferred from moving‐out case by 119 rescue services in Seoul of South Korea |
The number of social hymenoptera have decreased due to accelerated urbanization in Seoul, Korea, during the 1970s–1990s. However, recent changes in environmental conditions have brought distinct re‐growth of their colonies. In this study, we analyzed the re‐colonization trend of social hymenoptera in Seoul with moving‐... |
