The aim of this randomized, double-blind clinical trial was to evaluate the effect of the Paradontax dentifrice on the reduction of plaque and gingivitis. Subjects were randomly allocated into either the test group (n = 15, Paradontax) or the control group (n = 15, standard dentifrice with fluoride). Plaque levels were measured using the Turesky modification of the Quigley & Hein Plaque Index (...

STUDY DESIGN A retrospective comparative study. PURPOSE To provide an ideal correction angle of lumbar lordosis (LL) in degenerative flat back deformity. OVERVIEW OF LITERATURE The degree of correction in degenerative flat back in relation to pelvic incidence (PI) remains controversial. METHODS Forty-nine patients with flat back deformity who underwent corrective surgery were enrolled. Po...

OBJECTIVES To construct reference ranges of uterine artery Doppler parameters against gestation in twin pregnancies and to present charts of the pulsatility index (PI) and resistance index (RI) for clinical use. METHODS This was an observational study of the uterine circulation in 557 women with dichorionic twin pregnancies at 17-38 weeks' gestation. Uterine artery measurements were performed...

This paper presents a simple, but effective, design method for decentralized PI control systems with guaranteed closed-loop stability. Nyquist stability conditions are used to derive the stability region for each PI controller in terms of the controller parameters. A detuning factor for each loop is specified based on a diagonal dominance index. Then appropriate controller settings are determin...

background:   objective: to determine and compare uteroplacental circulation and obstetrics complications in pregnant women with pcos treated with metformin, aspirin and control group.   materials and methods: 105 pregnant women with pcos were enrolled in this study after assessing uterine artery pulsatility index (pi) with doppler ultrasonography at 12 weeks of gestation. the patients were div...

The aim of this study was to evaluate changes of microbiota in ten patients undergoing orthodontic treatment. For each patient clinical examination of gingival index (GI) and plaque index (PI) were performed at the first molars at: baseline (T1), 2 (T2), 4 (T3) and 12 weeks (T4). At the same time subgingival plaque and tongue samples were taken for the microbiological study. Clinical results sh...

BACKGROUND Previous studies have indicated the prognostic value of various laboratory parameters in cancer patients. This study was to establish a prognostic index (PI) model for breast cancer patients based on the potential prognostic factors. METHODS A retrospective study of 1661 breast cancer patients who underwent surgical treatment between January 2002 and December 2008 at Sun Yat-sen Un...

  Abstract Introduction: Mechanical plaque removal is the most reliable method of oral hygiene practice. However, to maximize its effect, it should be accompanied by the use of chemical agents such as toothpastes, mouth washes and fluoride gels. This study aimed to compare the effect of tooth brushing with an Iranian toothpaste compared to a commonly used foreign-made toothpaste on plaque in...

OBJECTIVES Fetal malnutrition (FM) implies soft tissue wasting at birth with significant postnatal consequences and morbidity, and is identified by clinical assessment (CAN score) and anthropometry. No previous studies have been done to study all these parameters and evolve a screening method. The aim of this study was identifying the incidence of FM using CAN score and compare the nutritional ...
