Comparative clinical efficacy of three toothpastes in the control of supragingival calculus formation.

Objectives: The purpose of this double-blind, parallel clinical study was to assess clinical efficacy in supragingival calculus formation reduction using Abhaibhubejhr Herbal Toothpaste compared to Colgate Total and Colgate Cavity Protection toothpastes.

Materials And Methods: A total of 150 subjects participated in the pretest phase. All subjects were given oral soft/hard tissue evaluation, calculus examination using Volpe-Manhold calculus, and whole mouth oral prophylaxis.

Comparing three toothpastes in controlling plaque and gingivitis: A 6-month clinical study.

Purpose: To investigate the clinical efficacy of three toothpastes in controlling established gingivitis and plaque over 6 months.

Methods: 135 subjects were enrolled in a single-center, double-blind, parallel group, randomized clinical study. Subjects were randomly assigned to one of three treatments: triclosan/copolymer/fluoride dentifrice containing 0.

The iontophoresis of lignocaine with epinephrine into carious dentine for pain control during cavity preparation in human molars.

Objective: To determine the effectiveness of the iontophoretic delivery of lignocaine with epinephrine through carious dentine for pain control during cavity preparation.

Design: The experiments were carried out on 56 carious molars that required class I restorations in 42 subjects (aged 15-20 years). The overhanging enamel and soft caries were removed then the sensitivity of the exposed dentine was tested with drilling, probing and air blast stimuli.

Effects of the iontophoresis of lignocaine with epinephrine into exposed dentine on the sensitivity of the dentine in man.

Objective: To determine the effects of the iontophoretic application of lignocaine and epinephrine to exposed dentine on the sensitivity of the dentine in human subjects.

Design: The experiments were carried out on 13 healthy premolars (13 subjects) that were scheduled for extraction. Dentine was exposed at the tip of the buccal cusp by cutting a cavity which was etched with 35% phosphoric acid.

Effect of the topical application of 50% lignocaine hydrochloride on the sensitivity of dentine in man.

Objective: To determine the effect of topical applications of 50% (w/v) lignocaine HCl on the sensitivity of human dentine.

Design: The experiments were carried out on 12 premolars scheduled for extraction as part of orthodontic treatment in nine subjects (ages: 16-29 years). Dentine was exposed by cutting a cavity at the tip of the buccal cusp of each tooth, and etched with 35% phosphoric acid.

Determination of plaque viability following a single brushing with commercial toothpastes.

Objective: The purpose of this study was to determine the viability of dental plaque at 12 hours following brushing with Colgate Great Regular Flavor (0.83% MFP), Crest Pro-Health (0.454% SnF), and Colgate Total Clean Mint Toothpaste (0.

Investigation of triclosan retention and dental plaque viability with a triclosan/PVM/MA copolymer mouthrinse in a Thai population.

This investigation studied triclosan retention and plaque viability in a group of healthy human subjects from Bangkok, Thailand, 12 hours after using a mouthrinse containing a triclosan/PVM/MA copolymer system. The results show the retained triclosan in the dental plaque was with in or higher than the minimum inhibitory concentration (MIC range 0.27-6.

Reduction of micronuclei in oral lichen planus supplemented with beta-carotene.

An elevated frequency of micronucleated exfoliated cells (MEC) in atrophic and erosive oral lichen planus (OLP) has been reported. To evaluate the effects of supplemental beta-carotene (BC) on MEC frequency in OLP lesions, we performed an open trial in 20 patients with atrophic and/or erosive OLP. Each patient received 15 mg of BC four times daily for 3 months.

Effects of potassium ions on dentine sensitivity in man.

Objective: To determine the effect of applying 500 mmol/l KCl at a pressure of 150 mm Hg above atmospheric to exposed dentine on pain sensation evoked by probing and air blast stimuli in human subjects.

Design: The experiments were carried out on 14 pairs of premolars in 14 human subjects (aged 17-30 years). Dentine was exposed at the tip of the buccal cusp, etched with acid and covered with saline, then 500 mmol/l KCl in Ringer's was applied at a pressure of 150 mm Hg for 4 min.

Frequency of micronucleated exfoliated cells in oral lichen planus.

Objective: The purpose of this study was to determine the frequency of micronucleated exfoliated cells (MEC) in atrophic and erosive oral lichen planus (OLP).

Materials And Methods: Twenty-two patients with atrophic and/or erosive OLP participated in this study. Lesions were scored ranging from 0 (no lesion) to 5 (large erosion) according to the severity and assessed for MEC.

Clinical effect of a triclosan containing dentifrice on gingivitis during pregnancy and post-partum.

One hundred forty pregnant women 3 months gestation were enrolled in a 9 month, double-blind clinical study to evaluate the effect of 0.3% triclosan/copolymer dentifrice on gingivitis, compared to a placebo dentifrice. Women were stratified into two balanced groups according to their baseline gingivitis scores.

Effect of Cha-em Thai mouthwash on salivary levels of mutans streptococci and total IgA.

The aim of this study was to investigate the effect of Cha-em Thai (Albizia myriophylla) mouthwash on the mutans streptococci (MS) and immunoglobulin A (IgA) level in saliva. Sixty-seven schoolchildren, age 6-12 years, with MS more than 1x10(5) cfu per milliliter of saliva were entered in this study. They were divided into two balanced groups according to their baseline MS counts (> or = 10(5) cfu/ml).
