Randomized Controlled Trial
Iontophoresis and topical application of 8% arginine-calcium carbonate to treat dentinal hypersensitivity.
The aim and the objectives were. (1) to assess the efficacy of a desensitizing toothpaste containing 8.0% arginine-calcium carbonate (Colgate® Sensitive Pro-Relief™), (2) to assess the efficacy of a desensitizing toothpaste containing 8.0% arginine-calcium carbonate (Colgate® Sensitive Pro-Relief™) used in combination with iontophoresis, and (3) to compare the effectiveness of the above methods. ⋯ Iontophoresis, when used along with Colgate® Sensitive Pro-Relief™ toothpaste, can provide additional benefit as this provides a better sealing effect.

Homocysteine (Hcy) is an independent risk factor for predisposing to atherosclerosis and endothelial dysfunction. Hcy levels increase with Vitamin B12 deficiency. The aim of this study was to investigate the association between carotid intima-media thickness (CIMT) and the autonomic modulation of heart rate variability (HRV) in early detection of atherosclerosis and impaired cardiac autonomic control in pediatric patients with Vitamin B12 deficiency. ⋯ Subclinical atherosclerosis was associated with cardiovascular autonomic imbalance in pediatric patients with Vitamin B12 deficiency. Homocysteinemia may be an important marker for the prediction of future cardiovascular disease.

Observational Study
Vulvovaginal candidiasis in reproductive age women in Enugu Nigeria, clinical versus laboratory-assisted diagnosis.
Clinical diagnosis of acute vulvovaginal candidiasis (VVC) depends on evidence of clinical symptoms, but symptomatic treatment widely practiced in low-resource area may lead to overdiagnosis and treatment. ⋯ Clinically based diagnosis of VVC has an unacceptably high false-positive rate which may encourage continued presumptive treatment with its attendant risks. Clinical evaluation and laboratory culture of vulvovaginal specimen should be the standard diagnostic method.

Comparative Study
TP53 polymorphisms in smokers' and nonsmokers' pericoronal follicles of asymptomatic impacted third molars.
The investigators designed and implemented a prospective cohort study composed of smoking and nonsmoking patients with asymptomatic fully impacted mandibular third molars. The objective of the paper was to evaluate 21 single-nucleotide polymorphisms (SNP) on the TP53 gene in smokers' (S) and nonsmokers' (NS) pericoronal follicles of asymptomatic impacted third molars. ⋯ Further studies should examine the entire TP53 gene to elucidate how smoking affects it in larger study populations.

Randomized Controlled Trial
Effect of radiotherapy on the coronal-sealing ability of two different root canal sealing materials.
This study aimed to assess the coronal-sealing ability of two different root canal obturation materials: gutta-percha with AH Plus and Resilon with Epiphany SE between radiated and nonirradiated groups. ⋯ Radiotherapy does not significantly affect the coronal-sealing ability of root canal obturation materials, gutta-percha/AH Plus and Resilon/Epiphany SE.
