The number of roots and canal configurations were evaluated using both the Vertucci and Benjamı´n Brisen˜ o Marroquı´n classification systems.

Methods: A total of 1084 second molar images (523 maxillary; 266 right and 257 left side and 561 mandibular; 285 right and 276 left side) were evaluated from 320 CBCT scans analyzed for the Turkish subpopulation.

Clinical outcomes of selective removal to soft dentin versus firm dentin for deep caries lesions: a randomized controlled trial up to 5 years.

Objectives: This study aimed to compare the success of selective removal to soft dentine (SRSD) with or without calcium silicate (CS) and selective removal to firm dentine (SRFD) in permanent dentition.

Materials And Methods: Between November 2018 and March 2020, 165 posterior deep caries lesions in 134 patients were included in the study and randomly assigned into test (n = 101) and control (n = 64) groups. The control group (n = 46) received the treatment of SRFD with CS, while the test group was further randomized into two groups to receive SRSD with CS (n = 45) and SRSD without CS (n = 45).

Regulatory issues related to the use of sodium hypochlorite solutions in endodontics.

Aim: To assess the regulation of sodium hypochlorite (NaOCl) solutions for endodontic usage in some of the world's main dental markets, in view of the European Union's recent move to classify antimicrobial root canal irrigants as high-risk devices under their Medical Device Regulation (MDR).

Methodology: The authors consulted legal texts available online and communicated with local health authorities wherever necessary to assess into which medical device category NaOCl solutions intended for endodontic application were subsumed. Furthermore, it was investigated whether there were sources outside the dental market to obtain NaOCl solutions for root canal treatments.

Evaluation of the Effectiveness of Active Vitamin D Use in Experimental Rat Lymphedema Model.

: Lymphedema is a progressive, chronic condition. Traumatic damage to the lymphatics, removal of lymph nodes, and/or radiation are the major causes of fibrosis and a subsequent pathological cascade. Macrophages play a crucial role in wound healing, with M1 macrophages known for their pro-inflammatory effects and M2 macrophages recognized for their anti-inflammatory effects, including improved angiogenesis, lymph angiogenesis, and tissue healing.

Mandible-First and Maxilla-First Sequencing in Virtual Surgical Planning for Orthognathic Surgery: Comparison of Planned and Actual Outcomes.

Recent studies have shown that virtual planning for orthognathic surgery is an accurate and repeatable method. It is also a fact that surgical sequence can affect the results in terms of accuracy. Various studies stated that both approaches offer comparable results when properly planned and implemented; however, further clinical studies are still needed.

Quercetin/Polyethyleneimine Modified Gold Nanoconjugates Inhibit Apoptosis and ROS Production Induced by Hydrogen Peroxide in DRG Sensory Neurons.

The basis of most neurological syndromes is the accumulation of free radical molecules. Quercetin is a polyphenolic bioflavonoid molecule and it has a very strong antioxidant effect by maintaining oxidative balance. There are many difficulties in the clinical use of quercetin due to its hydrophobic structure, low solubility, instability, poor oral bioavailability, and limited tissue-barrier penetration.
