Clinical evaluation of SonicFill bulk resin technique in the restoration of proximal deep caries of primary molars: a two-year randomized controlled trial.

Background/purpose: Traditional restorative composites require time-consuming incremental layering techniques which poses challenges in pediatric dentistry. SonicFill bulk resin allows for thicker layers to be placed efficiently, reducing treatment time and enhancing filling quality. This prospective, parallel, randomized, controlled clinical study aimed to compare the operative time and outcomes between SonicFill bulk resin and conventional restorative composite for deep proximal restorations in primary molars.

Co-Infection with Nocardia Terpene and Pneumocystis Jirovecii in a Patient with Anti-Synthetase Syndrome: A Case Report.

Background: Pulmonary infection is a common clinical complication associated with glucocorticoid. There have been no reported cases of mixed infections involving Nocardia and Pneumocystis jirovecii combined with anti-synthetase syndrome (ASS) activity.

Methods: This study conducted a retrospective analysis of the clinical data from a patient with active ASS, treated for a pulmonary coinfection.

Lifestyle and Social Factors Exacerbated on the Prevalence of Mood Disorders and Functional Dyspepsia Among Neonatal Nurses in China.

Background: Nursing is a high-stress occupation that can have an impact on mental health, particularly for neonatal nurses. Job-related stress factors and work-related behaviors have played a critical role in nurses' mental health. This study aimed to explore the prevalence of mood disorders and the impact of social factors, lifestyle on mood disorders among neonatal nurses.

Immunohistochemical localization of Pax6 in the developing tooth germ of mice.

Recent studies have reported that supernumerary teeth were observed in the maxillary incisor area in several Pax6 homozygous mutant mouse and rat strains. To date, it remains unknown whether Pax6 is expressed during tooth development in any species. The study aimed to analyze the expression of Pax6 during mouse incisor and molar development.

PAX6 polymorphisms in 20 Chinese children with supernumerary teeth in the maxillary incisor area.

Aim: To search for variants of PAX6 gene in patients with nonsyndromic supernumerary teeth in the maxillary incisor area (NSST) and compare genotypes and allele frequencies of the detected polymorphisms between the patients and controls.

Design: Twenty children with NSST and 31 controls were included. Genomic DNA was extracted from buccal epithelial cells of each individual.

[Occurrence of supernumerary upper incisor teeth in Pax6-/- mouse fetuses].

Objective: To investigate the occurrence of supernumerary upper incisor teeth in Pax6-/- mouse fetuses and to provide a model to explore the role of Pax6 in the upper incisor development and the mechanism of supernumerary teeth involving Pax6.

Methods: Twenty Pax6-/- mouse fetuses of strain DEBA were isolated on E18.5 (embryonic day).
