Objective: The aim of this study was to evaluate the effect of maintaining apical patency on periapical healing and postoperative pain levels in teeth with necrotic pulp and apical periodontitis.
Method And Materials: Fifty mature teeth with periapical lesions were randomly distributed into two treatment groups: patency, and nonpatency (n = 25). Patients were followed up over a 12-month period using clinical and radiographic assessments. The data were statistically analyzed using independent-samples t test and chi-square tests at a 95% confidence level (P = .05).
Results: Seventeen teeth in the patency group (85.0%) and 19 teeth in the nonpatency group (86.4%) were classified as being successfully treated (P = .900).
Conclusions: Within the limitations of the present study, maintaining apical patency did not affect endodontic treatment outcomes.

Despite advances in understanding molecular and cellular changes in the aging nervous system, the upstream drivers of these changes remain poorly defined. Here, we investigate the roles of non-neural tissues in neuronal aging, using the cutaneous PVD polymodal sensory neuron in Caenorhabditis elegans as a model. We demonstrate that during normal aging, PVD neurons progressively develop excessive dendritic branching, functionally correlated with age-related proprioceptive deficits.

Importance: Pelvic organ prolapse recurrence following native tissue repair occurs with composite failure rates of 9-19% within 12 months, predominantly involving apical/anterior compartments. Objective The objective of this study was to develop a novel vaginal orthosis (NVO) device prototype through an iterative design process based on investigator and user feedback.
Study Design: The NVO was designed based on pelvic floor biomechanical principles to mitigate unopposed intra-abdominal pressure of the anterior vagina by absorbing and redirecting intra-abdominal forces to the levator ani and tailored to accommodate postoperative vaginal caliber and axis.
Regulation of XOR function of reduced human L2/3 pyramidal neurons.

The apical dendrites of human L2/3 pyramidal neurons are capable of performing XOR computation by modulating the amplitude of dendritic calcium action potentials (dCaAPs) mediated by calcium ions. What influences this particular function? There is still no answer to this question. In this study, we employed a rational and feasible reduction method to successfully derive simplified models of human L2/3 pyramidal neurons while preserving their detailed functional properties.

Objective: This study aimed to evaluate the role of the chromodomain helicase DNA-binding protein 3 (CHD3) in tooth morphogenesis in Chd3 knockout mice.
Methods: Chd3 knockout mice were generated using the CRISPR-Cas9 method. Mandibular first molars were extracted from the mice and their littermates and morphometrically analyzed.

Stem cells derived from the apical papilla (SCAPs) play a crucial role in tooth root development and dental pulp regeneration. They are important seed cells for bone/tooth tissue engineering. However, replicative senescence remains an unavoidable issue as in vitro amplification increases.
