ReviewManagement of child patient behavior: quality of care, fear and anxiety, and the child patient.
Behavior management is a key component when providing dental care to children who have suffered traumatic dental injuries. This article reviews the current status of behavior management including basic communication techniques and advanced techniques used by pediatric dentists. ⋯ Little is known about the use of pharmacologic agents in managing young but behaviorally challenging patients who have suffered dental trauma. Future care involving sedation and specialized endodontic procedures of these young patients through collaborative efforts between endodontists and pediatric dentists seems promising and should be pursued.

Randomized Controlled Trial Comparative StudyEfficacy of articaine versus lidocaine in block and infiltration anesthesia administered in teeth with irreversible pulpitis: a prospective, randomized, double-blind study.
Profound pulpal anesthesia in posterior mandibular teeth with irreversible pulpitis usually requires administering an inferior alveolar nerve block (IANB) plus other supplemental injections. The purpose of this prospective, randomized, double-blind study was to compare the anesthetic success rate of buccal infiltration injections of articaine and lidocaine when supplemented with an IANB. ⋯ Supplementing an incomplete articaine IANB with articaine infiltration raises the anesthetic success more effectively compared with lidocaine in mandibular molars with irreversible pulpitis.

Randomized Controlled Trial Comparative StudyAnesthetic efficacy of the inferior alveolar nerve block in red-haired women.
The exact reasons for failure of the inferior alveolar nerve (IAN) block are not completely known, but red hair could play a role. The genetic basis for red hair involves specific mutations, red hair color (RHC) alleles, in the melanocortin-1 receptor (MC1R) gene. The purpose of this prospective randomized study was to investigate a possible link between certain variant alleles of the MC1R gene or its phenotypic expression of red hair and the anesthetic efficacy of the IAN block in women. ⋯ Red hair and the MC1R gene were significantly linked to higher levels of dental anxiety but were unrelated to success rates of the IAN block in women with healthy pulps.

Randomized Controlled Trial Comparative StudyA prospective, randomized single-blind evaluation of effect of injection speed on anesthetic efficacy of inferior alveolar nerve block in patients with symptomatic irreversible pulpitis.
Speed of injection may affect the solution spread in the pterygomandibular space. It was hypothesized that speed of injection will affect the anesthetic efficacy of inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis. ⋯ Rate of injection has no effect on anesthetic success of IANB, but slow injections were more comfortable than rapid injections.

Lipopolysaccharide induces the migration of human dental pulp cells by up-regulating miR-146a.
MicroRNAs are small noncoding RNAs that play crucial roles in regulating normal and pathologic functions. Bacterial lipopolysaccharide (LPS) is one of the key regulators of pulpal pathogenesis. This study investigated how LPS regulates microRNA expression and affects the phenotype of human dental pulp cells (DPCs). ⋯ The results suggested that LPS is able to increase the migration of DPCs by modulating the miR-146a-TRAF6/IRAK1 regulatory cascade.
