The effect of triclosan toothpaste on enamel demineralization in a bacterial demineralization model. (1/173)

Triclosan has been incorporated into toothpaste to enhance inhibitory effects on bacterial metabolism in dental plaque. Many studies have confirmed these effects by showing a reduction of accumulation of dental plaque, gingivitis and calculus. However, there is no evidence for triclosan having an inhibitory effect on the dental plaque-induced demineralization of the dental hard tissues. Therefore, the effect of 0.3% triclosan added to non-fluoride and fluoride toothpaste was tested in an in vitro model, in which bovine enamel specimens were to be demineralized by acids produced in overlaying Streptococcus mutans suspensions. In a first set of experiments the toothpastes were added to the S. mutans suspensions at 1:100, 1:1000 and 1:10,000 (w/v) dilutions. After 22 h incubation at 37 degrees C the suspensions were removed and assessed for calcium and lactate content, and pH. In this set of experiments, triclosan had no additive protective effect to the non-fluoride or fluoride toothpaste. In a second set of experiments, the enamel specimens were immersed daily for 3 min in 30% (w/v) slurries of the toothpastes before the 22 h incubation with the S. mutans suspensions. Under these conditions, triclosan showed an additional protective effect compared with non-fluoride toothpaste at a low concentration of S. mutans cells (0.07 mg cells dry weight per 600 microL suspension). It is concluded that the enamel surface may act as a reservoir for triclosan, which may protect the enamel surface against a mild acid attack. In combination with fluoride, however, as in toothpaste, triclosan has no additional protective effect against demineralization.  (+info)

Fluoride-releasing elastomerics--a prospective controlled clinical trial. (2/173)

A prospective controlled clinical trial was undertaken to evaluate the effectiveness of stannous fluoride-releasing elastomeric modules (Fluor-I-Ties) and chain (Fluor-I-Chain) in the prevention of enamel decalcification during fixed appliance therapy. Forty-nine patients (782 teeth) were included in the experimental group, where the fluoride-releasing elastomerics were used. Forty-five patients (740 teeth) who received non fluoride-releasing elastomerics formed the control group. All patients had their elastomerics replaced at each visit. Enamel decalcification incidence and distribution were recorded using an index by direct clinical observation. In the control group enamel decalcification occurred in 73 per cent of patients and in 26 per cent of all teeth. In the experimental group the corresponding incidence was 63 and 16 per cent, respectively. The overall reduction in score per tooth produced by the fluoride-releasing elastomerics was 49 per cent, a highly significant difference (P < 0.001). A significant difference was seen in all but the occlusal enamel zones. The majority (over 50 per cent) of lesions occurred gingivally. The teeth most severely affected were the maxillary lateral incisors and mandibular second premolars. There was no difference in treatment duration between groups.  (+info)

Study of the fluoridated adhesive resin cement--fluoride release, fluoride uptake and acid resistance of tooth structures. (3/173)

The objectives of this study, were to evaluate the fluoride release from fluoridate adhesive resin cement, fluoride uptake into surrounding tooth structures and the effect of their acid resistance. Several specimens were prepared using a plastic ring mould, from extracted human premolars, and prepared from enamel and dentin of the central area of the buccal surface of bovine teeth. The fluoride release rate of fluoridate adhesive resin cement (PN 200) per day was higher than other materials during the 7-day study period. Fluoride released and fluoride uptake by tooth structures was higher in the fluoridate adhesive resin cement. WDX analysis showed the fluoride concentration on dentin contact area was higher than that of enamel after 60 days of immersion in deionized water. The calcium release values were similar for enamel and dentin plates in the various test materials. The present findings indicated the important enhancement of tooth structure acid resistance by fluoridate material.  (+info)

Fluoride-releasing elastomeric modules reduce decalcification: a randomized controlled trial. (4/173)

OBJECTIVE: To determine whether fluoride releasing elastomeric modules reduced the incidence of decalcification around orthodontic brackets during a complete course of orthodontic treatment. DESIGN: A randomised controlled, split mouth design. SETTING: The study was carried out in the orthodontic department of Newcastle-upon-Tyne Dental Hospital, UK. SUBJECT AND METHODS: 21 consecutive patients (126 teeth) undergoing fixed appliance therapy were studied. A split mouth technique was adopted to examine the upper labial segment, where one side (left or right) was randomly assigned to the experimental group, and the opposite side served as a control throughout their course of orthodontic treatment. INTERVENTIONS: The control teeth were ligated to the archwire using conventional modules. The experimental teeth were ligated to the archwire using Fluoride releasing elastomeric modules. OUTCOME MEASURES: Standardised photographs were taken of the upper labial segment before and after completion of orthodontic treatment, and the degree of decalcification assessed in each tooth quadrant, using a modification of the Enamel Defect Score. RESULTS: Decalcification was found to occur in both treatment groups, though to a significantly greater degree on the control side (p = 0.002). The fluoride module side showed significantly fewer serious decalcified lesions than the control (p = 0.013). No patients withdrew from the study. CONCLUSIONS: It would appear that the use of fluoride releasing elastomeric modules reduces the degree of decalcification experienced during orthodontic treatment.  (+info)

Dental enamel formation and its impact on clinical dentistry. (5/173)

The nature of tooth enamel is of inherent interest to dental professionals. The current-day clinical practice of dentistry involves the prevention of enamel demineralization, the promotion of enamel remineralization, the restoration of cavitated enamel where demineralization has become irreversible, the vital bleaching of dental enamel that has become discolored, and the diagnosis and treatment of developmental enamel malformations, which can be caused by environmental or genetic factors. On a daily basis, dental health providers make diagnostic and treatment decisions that are influenced by their understanding of tooth formation. A systemic condition during tooth development, such as high fever, can produce a pattern of enamel defects in the dentition. Knowing the timing of tooth development permits estimates about the timing of the disturbance. The process of enamel maturation continues following tooth eruption, so that erupted teeth can become less susceptible to decay over time. Mutations in the genes encoding enamel proteins lead to amelogenesis imperfecta, a collection of inherited diseases having enamel malformations as the predominant phenotype. Defects in the amelogenin gene cause X-linked amelogenesis imperfecta, and genes encoding other enamel proteins are candidates for autosomal forms. Here we review our current understanding of dental enamel formation, and relate this information to clinical circumstances where this understanding may be particularly relevant.  (+info)

Varnish or polymeric coating for the prevention of demineralization? An ex vivo study. (6/173)

OBJECTIVE: The ability of an experimental coating, Odyssey, to prevent demineralisation ex vivo was compared with that of a fluoride varnish, Duraphat and a chlorhexidine-containing varnish, Cervitec. DESIGN: an ex vivo single-blind study. SETTING: Hard tissue research laboratory. MATERIALS AND METHODS: thirty bovine enamel blocks 0.5 cm x 1.5 cm were divided into 6 groups of 5 specimens. The enamel blocks were then allocated to one of 6 surface treatments. INTERVENTIONS: (1) surface left unprepared (control), (2) Duraphat application, (3) Cervitec application, (4) experimental polymer coating, (5) enamel conditioned with 10% citric acid and coated with the experimental polymer coating Odyssey (O + C), (6) enamel etched for 30 sec with 37% phosphoric acid and coated with the experimental coating (O + E). All specimens were cycled for 7 days through a daily procedure of demineralisation for 4 hours and remineralisation for 20 hours, and exposed to an equivalent of 2 months toothbrushing. A single operator blinded to the treatment allocation of each specimen carried artificial lesion depth assessment out using computer-assisted transverse microradiography. RESULTS: The control group had the greatest mean lesion depth (97.16 + 29.8 microm) with the Duraphat group exhibiting the lowest mean lesion depth (24.53 + 15.44 microm). The Duraphat, Odyssey, O + C and O + E groups all had significantly less lesion depth when compared with no surface preparation (p < 0.05 for all comparisons). There were no significant differences between any of the Odyssey groups. CONCLUSIONS: The efficacy of Duraphat application in preventing demineralisation ex vivo has been demonstrated in the present study, but clinical trials are required to assess its usefulness in orthodontic practice.  (+info)

A resin veneer for enamel protection during orthodontic treatment. (7/173)

The aims of this study were to test the tensile bond strength of a recently developed veneer. Sound premolar teeth (120) extracted for orthodontic purposes were divided into two experimental and two control groups. In one experimental group (V1) 4-META/MMA-TBB resin (4META) was used on the surface veneer prepared with micro particle filled resin (MFR) as an adhesive for bracketing and in the second group (V2) 4META was applied on the surface veneer with the trial resin. For the controls, in group R 4META was used on the enamel surface without veneer and in group G light-cured glass ionomer cement was applied. The 30 samples in each group were divided into three groups of 10 samples and thermal cycled (TC) at 3000, 10,000 or left uncycled. Tensile testing was carried out using an Instron machine. After tensile testing the bond failures in the experimental groups were recorded using a stereomicroscope. Statistical analysis was performed using ANOVA. In group V2 the resin veneer was able to maintain sufficient bond force to enamel during clinical use. The bond strength of group V1 was significantly higher than that of groups R (P < 0.05) and G (P < 0.01) at TC 0, but for both TC 3000 and 10,000, the bond strength of group V1 was lower than groups R and G, respectively. There were significant differences between groups V1 and R (P < 0.01) for TC 3000, and between groups V1 and R and G (P < 0.01) at TC 10,000. The bond strength of group V2 was almost equal to that of group R at TC 0. At TC 3000, group V2 showed significantly lower bond strength than group R (P < 0.05), but no significant difference was found compared with group G. At TC 10,000, there were no significant differences between groups V2, R or G. When comparing groups V1 and V2, the bond strength of group V1 was significantly higher than that of group V2 (P < 0.01) at TC 0, but the bond strength of group V1 was significantly lower than that of group V2 for both TC 3000 (P < 0.05) and TC 10,000 (P < 0.01). Comparison between groups R and G, showed that the bond strength of group R was significantly higher than that of group G for both TC 0 (P < 0.01) and TC 3000 (P < 0.01), but no significant difference was found for TC 10,000. In group V2, nine samples showed adhesive failure between the veneer surface and bracket adhesive before thermal cycling. There were significant differences between the MFR and both trial resin and glass ionomer cement (P < 0.01) when examining thermal expansion. No significant difference was found between the trial resin and glass ionomer cement. It is suggested that application of a resin veneer prior to bracket bonding is suitable for clinical application to protect the teeth and to prevent decalcification and caries.  (+info)

Effect of experimental fluoride-releasing tooth separator on acid resistance of human enamel in vitro. (8/173)

This study aimed to investigate the fluoride-releasing ability of an experimental tooth separator consisting of polyurethane elastomer with tin fluoride and its effect on the acid resistance of human enamel. The tooth separator was set around an enamel slab and stored in de-ionized water for 10 days. The daily concentration of fluoride in the de-ionized water was measured. Then the enamel surface was artificially decalcified by a lactic acid buffer solution (pH 4.5) for 96 hours. The mineral density at the surface layer of the enamel was measured to evaluate the acid resistance. The fluoride release increased with the amount of fluoride in the separator, but decreased with the immersion time. Both the enamel area contacting with the separator and its surrounding area showed lower mineral loss and lesion depth compared with the controls (P < 0.05). It is suggested that the experimental tooth separator would release enough fluoride and improve the acid resistance of the enamel surface layer.  (+info)

INTRODUCTION. Dental plaque left undisturbed over teeth is implicated in dental caries development, and, in the presence of frequent exposure to sucrose, white spots are clinically detected after 14-21 days7,22. Using sensitive laboratory methods to assess enamel demineralization it was demonstrated that even shorter periods were enough to cause enamel alterations2,16. However, the relationship between salivary factors, period of dental plaque accumulation, and dental caries deserves further research.. It has been assumed that plaque cariogenicity is influenced by a dynamic interaction of dietary and salivary, microbiological and biochemical factors. Salivary flow rate, buffer capacity and mutans streptococci counts were significantly related to caries occurrence in some studies9,19, and the evaluation of these factors has been proposed as a tool for caries risk assessment; but the associations with caries are normally weak. Also, mutans streptococci counts in plaque are considered to be ...

This is Part 2 of an in vitro study investigating two techniques for recording and quantifying demineralization surrounding orthodontic brackets. In Part 1 the repeatability of computerized image analysis from digitally converted photographic slides and quantitative light‐induced fluorescence (QLF) was explored. In Part 2 of the investigation the validity of each technique was examined.. Thirty halved human molars, shaped to look like incisors and with an orthodontic bracket bonded to the buccal surface were used. A small area of each of the four edges of the bracket was variously exposed to a demineralizing gel for 0, 3, 7, or 14 days. Images of the teeth were taken and analysed using the two techniques. Repeat images and analysis were carried out blind. The sensitivity, specificity, positive, and negative predictive values were calculated.. A negative result confirmed that there was no demineralization present in the majority of cases. A positive result was less reliable particularly for the ...
Enamel demineralization is a concern in orthodontic patients with poor oral hygiene. To curtail this problem, amorphous calcium phosphate (ACP) containing adhesives have been developed. The purpose of this in vitro study was to evaluate the cariostatic potential of an ACP containing orthodontic bonding agent adjacent to brackets. Sixty human molars were randomly distributed into: ACP adhesive, resin modified glass ionomer cement (RMGIC), and conventional composite resin groups (N=20 each). Brackets were bonded following the manufacturers instructions. Tooth enamel through a 2mm window around the brackets was cycled in demineralization (6 hrs) and remineralization (18 hrs) solutions. After 14 days, teeth embedded in resin and were sectioned. Knoop indentations were performed to determine enamel hardness. There were no statistically significant differences between the control and experimental groups. However, both Fuji Ortho LC (RMGIC), and Aegis Ortho (ACP) showed a trend toward a reduction in

A demineralized bone matrix is produced by a process in which a bone body is placed in a first processing solution comprising an acid to demineralize the bone body. The bone body is periodically removed from the first solution at specific time intervals to perform at least one test, such as a compression test, on a mechanical property of the bone body. When the test yields a desired result, the bone body is exposed to a second processing solution that is less acidic than the first, thus minimizing the exposure of the bone body to the harsh acidic conditions of the demineralization phase of the process.
Shrimp industries produce waste in the form of the tail, head, and skin. These materials can be further processed into chitin by demineralization and deproteinization. By removing the acetyl group of chitin, chitosan was obtained. Both characteristics of products are influenced by degree of deacetylation, solubility, viscosity, and molecular weight. To obtain high quality of chitosan, the quality of chitin is improved by optimizing demineralization and deproteinization. In this research, before demineralization and deproteinization the boiling process was conducted. In addition, the sequence of those processes was randomized, such as demineralization-deproteinization and deproteinization-demineralization. The study was conducted by treating the dried shrimp shell waste through the boiling process, the process deproteinasi using NaOH solution, demineralization using HCl solution, and followed by deacetylation process using NaOH solution. The entire processes were carried out in a series of ...

The reason for reddish shade after bleaching with peroxide is the high content of manganese, Mn (2+)→colourless but Mn (7+ )→ violet. The contents of Fe, Mn, Ca and Mg varies depending upon the origin of cotton . With the demineralization treatment the mineral content of cellulosic substrates can be reduced substantially and thereby diminishing the negative influence of earth alkali and heavy metal ions in subsequent process operation. Complexion of earth alkali salts (Ca and Mg) is possible in the acid medium and heavy metals (Fe and Mn) is possible in alkaline medium. The advantages and benefits of the demineralisation are : better levelness and more brilliance in the dyeing process, lower peroxide consumption, reduction in the ash content, increase in degree of whiteness, regular decomposition of peroxide, no catalytic damage of the fibres (holes) and possibility of replacement of hypochlorite bleach. Generally good pre-treated materials should have 100-300 p.p.m, of Ca and Mg and 4-8 ...

This study sought to gain insights into the steps leading to remineralization and mechanical recovery of hydrated dentin. Mechanical recovery in water was hypothesized to result from effective mineral matrix binding and to occur from the innermost regions outwards due to an increase in the number of nucleation sites. Partially demineralized (0.05 M acetate, pH=5.0, 8 h) dentin was remineralized using calcium and phosphate solutions of 10.1 or 9.8 degree of saturation (DS) for hydroxyapatite (pH=7.4) for 4, 8 or 24 h. Remineralization used a constant solution composition approach, which allowed for a continuous mineral growth with relatively constant thermodynamic driving forces. Crystal growth rates (R) were calculated using concentrations of calcium and phosphate. Before and after de- and re-mineralization, specimens had their surface and cross-section elastic moduli measured using AFM-nanoindentation in water. DS=10.1 provided higher R and higher mechanical recovery at the surface (p,0.0001). ...

The salivary protein, statherin, plays an important role in enamel homeostasis. It forms a bioactive complex with calcium and phosphate releasing these ions when pH decreases. Statherin also forms part of the enamel pellicle forming a protective barrier against bacterial and dietary acids. The purpose of this thesis was two-fold: firstly, to study the effect of a 21 amino acid peptide identical to the N terminus of Statherin (StN21) on enamel de - and remineralisation in vitro and secondly, to undertake biocompatibility assays of this peptide to demonstrate its safety for use in a clinical trial. X-ray microtomography (XMT) is a quantitative, non-destructive method of measuring mineral change. Using XMT to quantify mineral changes, StN21 demonstrated a statistically significant decrease in demineralisation rate when compared to control lesions exposed to phosphate buffered saline (PBS). Whole Statherin protein and sodium fluoride solutions were used as positive controls and were found to have ...

Y1 - 2014/4. N2 - Purpose: A technology based on fluorescence imaging with reflectance enhancement (FIRE) was validated for early detection of caries. Methods: In Phase-I, caries-like lesions were created in a defined window on 85 teeth by 14-day demineralization in acidified gel. During demineralization, teeth were examined for caries every 6 hours for 24 hours, and thereafter daily by visual examination (VE), FIRE, Quantitative light-induced Fluorescence (QLF), and DIAGNOdent pen (DDp). Five teeth were withdrawn after each examination. A tooth slice was cut from each window and examined under polarizing-light microscopy (PLM) for lesion presence/absence and lesion depth quantification. In Phase-II, 56 teeth assembled on mouth models were examined twice by two dentists for caries using the four methods. Each ...

Seoul, Republic of Korea - Today at the 94th General Session & Exhibition of the International Association for Dental Research, researcher Angus Walls, Edinburgh Dental Institute, Scotland, UK, will give a Keynote Address titled What is the Role of Diet in Caries Prevention? The IADR General Session is being held in conjunction with the 3rd Meeting of the IADR Asia Pacific Region and the 35th Annual Meeting of the IADR Korean Division.. Dental caries are caused by bacterial fermentation of dietary sugars that result in the production of acids just below the critical pH for demineralization of enamel and dentine. This process is dynamic because saliva is an efficient remineralizing solution that can repair acid-mediated demineralization. However, there are limits to the extent of demineralization that can be repaired by the action of saliva, and this ability is impaired in people with xerostomia. Strategies for caries prevention can have two approaches, prevention of demineralization and ...
An in-vitro study was undertaken to evaluate the effect of Panavia-21 and ProBOND In retention and microleakage of amalgam restorations. 40 freshly extracted molar teeth were subjected for retention test while another 40 teeth were selected to evaluate microleakage. They were divided into 4 groups of 10 each. After laboratory procedures, the samples submitted for retention test were examined under SEM. Results were statistically analysed. To assess microleakage the samples were submitted to thermocycling, later the teeth were immersed in 5% methylene blue dye and the extent of dye penetration was evaluated by Stereomicroscope. The Statistical analysis of the results of retention test showed that Group IV required highest force to dislodge amalgam restorations when compared to other 3 groups. Whereas the statistical analysis of the results of the microleakage showed that Group IV exhibited less microleakage when compared to other groups. The study concludes that Bonded Amalgam Restorations are ...

Tooth enamel is the hardest substance in the human body. Its like the castle walls, protecting the softer dentin and pulp inside each tooth. Unfortunately, it is porous and vulnerable to erosion by acids. When the enamel loses minerals to acid exposure (a process called demineralization), it weakens the teeth and leaves them more susceptible to decay. However, we can fortify that enamel by getting enough minerals and nutrients, remineralizing our teeth. This is the battle our mouths are fighting every day: demineralization versus remineralization. The invaders in this battle are bacteria. They feed on sugar and carbs left in our mouths after a meal, and they excrete enamel-eroding acid onto our teeth. Luckily, we have a natural defense against the bacteria, and thats our saliva. If enamel is like castle walls, then saliva is like the moat. A lot of harmful bacteria falls into this moat and gets washed away instead of being able to attack the castle walls. To learn more about what harmful ...
Dental caries, also known as tooth decay or a cavity, is an infection, usually bacterial in origin, that causes demineralization of the hard tissues (enamel, dentin, and cementum ) and destruction of the organic matter of the tooth, usually by production of acid by hydrolysis of the food debris accumulated on the tooth surface. If demineralization exceeds saliva and other remineralization factors such as from calcium and fluoridated toothpastes, these tissues progressively break down, producing dental caries (cavities, holes in the teeth). The two bacteria most commonly responsible for dental cavities are Streptococcus mutans and Lactobacillus. If left untreated, the disease can lead to pain, tooth loss, and infection. Today, caries remain one of the most common diseases throughout the world.. Caries can be classified by location, etiology, rate of progression, and affected hard tissues. These forms of classification can be used to characterize a particular case of tooth decay in order to more ...
There are numerous well documented medical studies that show the deleterious affect of soft drinks on dental enamel. Non-cola beverages fared worst and dental problems were greatly accelerated by both regular and dietetic drinks, though the absence of sugar lessened decay. Recently sports drinks have been added to the studies with the surprising finding that they result in enamel deterioration equal to or worse than the non-cola beverages! Several different mechanisms are at work but the main problem is that almost all of these products contain phosphoric or citric acid. Other organic acids such as malic and tartaric are often present as well. These acids are very erosive to dental enamel due to their ability to chelate calcium. They are efficient buffers and keep oral pH well below the optimal salivary pH of 6.5 to 7.5. The threshold level for the development of dental caries is below Ph 5.5. Enamel demineralization occurs with prolonged exposure to lower pH or frequent cycling between optimal ...

Acquisition of the ability to make polysaccharides from sucrose, we. and anthropological elements. In humans, oral caries is thought as the demineralisation of tooth with the bacterial creation of organic acidity from fermentable substrates such as for example monosaccharides, oligosaccharides, and prepared polysaccharides1,2,3. The oral caries pandemic continues to be previously talked about from an anthropological and archaeological viewpoints in terms of the consumption WZ8040 of fermentable carbohydrates4,5,6,7. Indeed, the emergence of dental caries positively correlates with the increased consumption of carbohydrates through the main source, grain8,9, following the introduction of prehistoric farming. At that time, the degree of caries was comparatively moderate, since oral bacteria produced only low amounts of organic acid. However, the widespread use of processed sugar during the industrial revolution due to improvements in food processing techniques, stabilisation of plantation-based ...

This is a strong antibacterial chemical which obviously has some recovery residential or commercial properties. However, not all toothpaste has this active ingredient, and not every person reacts similarly to it. An additional element is that some individuals have dry skin and this can cause troubles especially if you leave the toothpaste on too lengthy as it could truly dry the skin which is something you do not want as this could cause irritation and redness, which is the opposite outcome you are trying to find! Something else to consider is that toothpaste was never created to cure or alleviate acne.. Now that does not indicate you must not use it, but it is something to consider due to the fact that we are discussing a delicate problem right here, that of dealing with acne, and some individuals may belittle the suggestion of using toothpaste to treat it, whereas others will certainly say that they have actually been utilizing it for many years and has actually functioned fine for them.
