Prevalence of and factors associated with maxillary sinus cyst in a Chinese population
This study used cone-beam computed tomography (CBCT) to assess the prevalence of and factors associated with maxillary sinus cysts (MSCs) in a Chinese population.METHODS: A total of 2,571 CBCT scans of 5,000 sinuses were analyzed. MSCs were diagnosed on the basis of imaging features within the maxillary sinus. Sex, age, dental condition, and anatomic condition were assessed. Associations with these factors were evaluated with logistic regression and a generalized estimating equations model.RESULTS: The prevalence of MSCs was 15.46% at the sinus level and 23.44% at the patient level. The prevalence of MSCs was higher for men (OR = 1.864, P

Translation and validation of an ageism scale for dental students in Switzerland
This study aimed to validate an ageism scale for dental students in Switzerland.METHODS: The original scale was first translated to German and then evaluated by 14 experts for relevance; four items were eliminated. Validation of the resulting questionnaire was performed at three Swiss dental schools. Principal component analysis (PCA) was performed; Cronbach's alpha (α) was used to assess the internal consistency reliability, and Pearson's coefficient to identify any correlations with demographic parameters (P

Hepatocyte growth factor exhibits anti-fibrotic effects in an in vitro model of nifedipine-induced gingival overgrowth
CONCLUSION: This study demonstrated the establishment of an in vitro model of nifedipine-induced gingival overgrowth by showing increased collagen levels.

Epub 2021 Dec 29.ABSTRACTPURPOSE: The aim of this study was to use dye penetration to measure apical and coronal leakage simultaneously in single-canal teeth that had been treated endodontically using a single-cone obturation technique.METHODS: One hundred single-canal, extracted human teeth were cleaned and shaped with ProTaper NEXT rotary files to size-X5 (50/.06), then randomly assigned to five sealer groups for single-cone gutta-percha obturation. The teeth were soaked in 0.6% rhodamine B at 37°C for seven days, then the roots were ground mesiodista...

A single-center prospective pilot open-label study to assess the efficacy of topical application of an oxygen-enriched oil for the treatment of angular cheilitis
CONCLUSION: Even if with limitations, data showed that this medical preparation facilitated prompt recovery from reported pain, without adverse reactions. Further work with a larger study population, and possibly a randomized control medication, will be needed.PMID:34980827 | DOI:10.2334/josnusd.21-0428 (Source: Journal of oral science)

Coronal and apical leakage among five endodontic sealers
J Oral Sci. 2021 Dec 29. doi: 10.2334/josnusd.21-0433. Online ahead of print.ABSTRACTPURPOSE: The aim of this study was to use dye penetration to measure apical and coronal leakage simultaneously in single-canal teeth that had been treated endodontically using a single-cone obturation technique.METHODS: One hundred single-canal, extracted human teeth were cleaned and shaped with ProTaper NEXT rotary files to size-X5 (50/.06), then randomly assigned to five sealer groups for single-cone gutta-percha obturation. The teeth were soaked in 0.6% rhodamine B at 37°C for seven days, then the roots were ground mesiodistally and...

Prevalence of and factors associated with maxillary sinus cyst in a Chinese population
This study used cone-beam computed tomography (CBCT) to assess the prevalence of and factors associated with maxillary sinus cysts (MSCs) in a Chinese population.METHODS: A total of 2,571 CBCT scans of 5,000 sinuses were analyzed. MSCs were diagnosed on the basis of imaging features within the maxillary sinus. Sex, age, dental condition, and anatomic condition were assessed. Associations with these factors were evaluated with logistic regression and a generalized estimating equations model.RESULTS: The prevalence of MSCs was 15.46% at the sinus level and 23.44% at the patient level. The prevalence of MSCs was higher for men (OR = 1.864, P

Sealing ability of two root-end filling materials at different retro-preparation lengths
CONCLUSION: Biodentine showed significantly lower ML when compared to Super-EBA and no statistical significative differences were observed when samples were retro-prepared at 3 mm or 9 mm.PMID:34980823 | DOI:10.2334/josnusd.21-0309 (Source: Journal of oral science)
