Treatment of cavities with citric acid cavity cleanser, also used as an etchant, before restoration with zinc oxide-eugenol cement, was toxic to the human dental pulp in comparison to sham-treated controls. The cleanser caused a significantly (P less than .01) greater intensity and incidence (P less
OBJECTIVE
This study determined recession rates of peritubular dentin and intertubular dentin in citric acid solution (0.018M, pH=2.5) for caries-affected transparent dentin, one of the major components of dentin substrate as altered by caries, with comparisons made with non-carious
Saliva, via its lubricating, cleansing, remineralizing, antibacterial, and buffering actions, is an important protective factor for both dentition and soft tissue. Xerostomia is commonly found in older individuals due to the use of medications or medical conditions, such as Sjögren's, which directly
Background: Economically motivated adulteration (EMA) of foods has become an increasing concern in recent years, with lemon juice as a popular target. Objective and Method: In this work, an optimized preparation procedure for the isolation of citric acid from lemon juice was validated
This report concerns long-term (4 to 5 years) clinical evaluation of 22 resolved (complete bone closure) mandibular Class 2 furcation defects following coronally advanced flap procedures and citric acid root treatment with or without adjunctive implantation of freeze-dried, demineralized allogeneic
Acid-treatment of root surfaces as adjunct to periodontal reconstructive surgery may have deleterious effects on that part which remains in a supragingival location after healing. The present experiment aimed to examine whether recalcification of such root surfaces may occur. Cylindrical blocks of
The purpose of this study was to see if the root surface topography of teeth, stored in saline and subsequently treated with citric acid, differred from the root surface topography of teeth that were treated immediately upon extraction, 12 freshly extracted adult human permanent teeth, with proximal
Salivary α-amylase (sAA) is responsible for the 'pre-digestion' of starch in the oral cavity and accounts for up to 50 % of salivary protein in human saliva. An accumulating body of literature suggests that sAA is of nutritional importance; however, it is still not clear how sAA is related to
The condensation and evaporation processes of semi-volatile organic compounds (SVOCs) in atmospheric aerosols can induce significant evolutions of their chemical and physical properties. Hence, for interpreting and predicting composition changes of atmospheric aerosols, it is indispensable to
The purpose of this study was to investigate whether plaque bacteria invade the exposed radicular dentin after root planing or chemical root treatment in vivo. Eighteen caries-free human periodontally involved teeth with hopeless prognoses were studied. Fourteen teeth were scaled and root planed
Exposure of the oral cavity to acidic solutions evokes not only a sensation of sour, but also of sharp or tangy. Acidic substances potentially stimulate both taste buds and acid-sensitive mucosal free nerve endings. Mice lacking taste function (P2X2/P2X3 double-KO mice) refuse acidic solutions
The aim of this study was to determine the pulpal response to three dilute citric acid smear removers. Forty-eight vervet monkeys (Cercopithecus aethiops pygerythrus), in three groups of sixteen animals provided 384 tooth specimens for the histological evaluation of the pulpal response at 3, 31, and
