Effect of non-surgical periodontal therapy on risk markers of cardiovascular disease: a systematic review and meta-analysis.

Background: Cardiovascular disease (CVD) is the leading cause of mortality in the world. Patients with periodontitis have a higher risk of CVD, although a causal relationship between these conditions remains unclear. Non-surgical periodontal therapy (NSPT) is able to control inflammation at local and systemic levels.

Regulatory effect of 17β-estradiol on the expression of β-defensin-2 and proinflammatory cytokines in human oral epithelial cells.

Background: Although estrogen deficiency has been proposed as a risk factor for oral mucosal inflammatory diseases in post-menopausal women, the mechanisms involved remain unclear. This study aimed to investigate the effect of 17β-estradiol (E2) on the inflammatory response stimulated by interleukin-1 beta (IL-1β) in human oral mucosal epithelial cells (hOMECs) and its possible mechanism.

Methods: Primary hOMECs were obtained from female infants and cultured in keratinocyte growth medium.

[Evaluation of the cavity cleaning of ultrasonic instruments and slow-speed handpiece in posterior teeth root-end preparation].

Purpose: To compare the cleanliness of root end preparations by using ultrasonic instrumentation and slow-speed handpiece.

Methods: Thirty-two mesial roots of the first mandibular molars with two canals and mature root apices were assigned randomly to 2 groups, each group had 16 teeth. The root-end preparations were made respectively using ultrasonic diamond tip Berutti and NiTi tip RE2 and slow-speed handpiece with No.

[Effects of different instruments in root-end preparation: scanning electron microscopic evaluation].

Purpose: To evaluate the effects of retrograde preparation between ultrasonic retrotips and traditional slow-speed handpiece.

Methods: 27 maxillary second bicuspid teeth with two canals and one isthmus were divided randomly into 3 groups with 9 in each. The root-end preparations were made respectively using ultrasonic diamond tip Berutti and NiTi tip RE2, ultrasonic #40K file and slow-speed handpiece with NO.
