Abstract
Nanotechnology has paved multiple ways in preventing, reversing or restoring dental caries which is one of the major health care problems. Nanotechnology aided in processing variety of nanomaterials with innovative dental applications. Some showed antimicrobial effect helping in the preventive stage. Others have remineralizing potential intercepting early lesion progression as nanosized calcium phosphate, carbonate hydroxyapatite nanocrystals, nanoamorphous calcium phosphate and nanoparticulate bioactive glass particularly with provision of self-assembles protein that furnish essential role in biomimetic repair. The unique size of nanomaterials makes them fascinating carriers for dental products. Thus, it is recentlyclaimedthat fortifying the adhesives with nanomaterials that possess biological meritsdoes not only enhance the mechanical and physical properties of the adhesives, but also help to attain and maintain a durable adhesive joint and enhanced longevity. Accordingly, this review will focus on the current status and the future implications of nanotechnology in preventive and adhesive dentistry.

Abstract
OBJECTIVES To compare CPP-ACP, Tri-calcium phosphate and Hydroxyapatite on remineralization of artificial caries like lesions on primary enamel. STUDY DESIGN Ten extracted Primary molars coated with nail varnish, leaving a window of 2×4 mm on buccal and lingual surface were immersed in demineralizing solution for 96 hours and sectioned longitudinally to obtain 40 sections (4 sections per tooth) and were randomly divided into 4 groups (A to D) n=10; Group A: negative control, Group B: CPP-ACP, Group C: Tri-calcium phosphate, Group D: Hydroxyapatite. Sections were subjected to pH cycling for 10 days and were evaluated by polarized light microscope before and after treatment. RESULTS Intra group comparison of demineralization and remineralization was done by paired t-test. One way ANOVA was used for multiple group comparisons followed by post HOC TUKEY'S Test for group wise comparisons. Remineralization was found more with Group D followed by Group B, C and A. CONCLUSION Hydroxyapatite showed better remineralization when compared to CPP-ACP and Tri-calcium phosphate.

Abstract
AIM To evaluate the effect of dentifrice with varying concentrations of fluoride on surface microhardness of fluorosed enamel as compared to a non-fluoridated dentifrice. STUDY DESIGN In vitro, comparative type. METHOD 60 enamel blocks with score-3 enamel fluorosis were randomly divided into three groups: Group I non-fluoridated dentifrice, Group II 1000-ppm fluoridated dentifrice and Group III 1400-ppm fluoridated dentifrice. After evaluating the baseline surface microhardness, samples from each group were brushed for 2 min, twice daily for a period of 21 days with 0.02 g of respective interventional agents as per protocol. Microhardness of the samples was re-evaluated at the end of 21 days. Statistical analysis was performed using paired t test, ANOVA and Kruskal-Wallis test. RESULTS The surface microhardness within the group from the baseline to 21st day post intervention, showed a statistically significant increase in all three groups, hence indicating that all the three interventional agents used were effective against the fluorosed enamel surface. Intergroup comparison of the surface microhardness of fluorosed enamel from baseline to 21st day post intervention showed a statistically significant difference (p < 0.001) amongst the groups with Group III proving most effective followed by Group I and Group II. CONCLUSION 1400-ppm fluoridated dentifrice is more effective as compared to 1000-ppm fluoridated dentifrice and non-fluoridated dentifrice in increasing the surface microhardness of fluorosed enamel.

Abstract
INTRODUCTION The caries process has been thought to be irreversible, resulting in the permanent loss of tooth substance and eventually the development of a cavity. Recent approaches focused on application of remineralizing agents to incipient carious lesions, aim at controlling demineralization and promoting remineralization. Remineralizing agents create a supersaturated environment around the lesion; thus, preventing mineral loss and forces calcium and phosphate ions in the vacant areas. AIM To compare and evaluate the remineralization potential of Fluoride Varnish, CPP-ACP Paste (Casein Phosphopeptide-Amorphous Calcium Phosphate) and fTCP Paste (functionalized Tricalcium Phosphate) using confocal microscope. MATERIALS AND METHODS Two windows of 3X3mm were created on the labial cervical and incisal thirds in 60 permanent maxillary central incisors. The teeth were demineralized to create artificial caries and divided into three groups of 20 each. Group I specimens were coated with Fluoride Varnish once whereas those in CPP-ACP paste group and fTCP group were brushed for 2 minutes, twice daily for 20 and 40 days. The specimens were stored in artificial saliva during the study period and were later sectioned and observed under confocal microscope. Data obtained was statistically analyzed using Fischer's exact test, ANOVA and post-hoc Bonferroni's test. RESULTS Fluoride Varnish, CPP-ACP Paste and fTCP Paste showed remineralization of artificial carious lesions at both the time intervals. Fluoride varnish showed the highest remineralization followed by CPP-ACP Paste and fTCP Paste. A statistically significant increase in remineralization potential of CPP-ACP Paste and fTCP Paste was observed at the end of 40 days as compared to 20 days. CONCLUSION Fluoride varnish showed the greatest remineralization potential of artificial carious lesions followed by CPP-ACP Paste and fTCP Paste respectively.

Abstract
AIM To evaluate (1) the remineralizing potential of Tooth Mousse(®) (TM) on artificial carious lesions, when applied for 1 min, and (2) the benefit of a fluoridated dentifrice prior to TM application. METHODS Demineralisation caries-like lesions 120-200 μm deep were produced by placing molars in demineralizing solution for 96 h, sections 100-150 μm thick were then randomly assigned to four groups. Specimens were treated thrice daily with a non-fluoridated (Group A), or fluoridated dentifrice (1000 ppm) (Group B), or TM (Group C), or a fluoridated dentifrice followed by TM (Group D) then subjected to a 10-day pH cycling model. Lesion evaluation involved polarizing light microscopy and microradiography. RESULTS Application of TM in isolation (Group C) for 1 min resulted in significant increase in lesion depth (LD), however, an increase in mineral content deposition (V max) was not significant. Post treatment LD increases were greatest in Group A, then Group C and Group B respectively. A decrease in LD (by 19.9 %) was noted only after fluoridated dentifrice and TM (Group D) were applied consecutively for 1 min each (p < 0.05). Mineral content deposition was also greatest in this group (Group D) and both V max and LD changes were statistically significant when compared to other groups. CONCLUSIONS TM alone failed to remineralize carious lesions when applied for 1 min. However, remineralization occurred after a prior application of a fluoridated dentifrice.

Abstract
BACKGROUND This study evaluated the effect of pastes containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) with and without fluoride on enamel demineralization. METHODS Human enamel blocks were used and after incipient caries-like lesions were formed, they were assigned to four groups: G1 - saliva; G2 - MI Paste (RecaldentTM ); G3 - MI Paste Plus (RecaldentTM 900 ppm as NaF); and G4 - Crest™ (1.100 ppm as NaF). The specimens were soaked in demineralizing solution for 6 hours and remineralized in artificial saliva for 18 hours alternatively for 10 days. The dentifrice was prepared with deionized water in a 1:3 proportion (w/w) or applied undiluted in the case of the CPP-ACP formula. Demineralized enamel changes were analysed by surface microhardness (SMH), 3D-profilometry and SEM. Data were analysed by non-parametric Kruskal-Wallis and Mann-Whitney test comparisons and one-way ANOVA and Tukey's HSD post hoc test (α = 0.05). RESULTS The SMH values observed in the G2 (47.8 ± 28.5) and G3 (53.6 ± 27.6) groups were different from that of G4 (90.2 ± 17.1), which were significantly higher than that found in G1 (39.4 ± 14.2). The %SMH was significantly lower in G4 when compared to G1 (p < 0.001) and G3 (p < 0.05). CONCLUSIONS MI Paste Plus demonstrated a greater protective effect against demineralization than MI Paste and showed smoother surfaces.

Abstract
OBJECTIVES The aim of the present study was to evaluate the percent mean mineral density (MD) change of early caries lesions after the application of silver diamine fluoride (SDF) or glass ionomer cement (GIC). MATERIALS AND METHODS This double-blind, crossover study involved two experimental phases of 28 days each. Thirty-two pairs of enamel slabs were created from the proximal surfaces of 16 premolars. Each pair of artificial carious slabs was randomly divided into the control or test group (38 % SDF or GIC). The slabs were attached to orthodontic brackets and bonded to the maxillary first permanent molars of 16 subjects for 28 days. After a 7-day washout period between phases, the subjects received the other material for the second phase. The mean MD of the lesions was measured by microcomputed tomography. RESULTS SDF yielded a percent mean MD increase at a depth of 0-84 μm, although increase in the GIC group was observed at a depth of 24-108 μm. The percent mean MD changes of the SDF and GIC groups were similar (p = 0.100) and significantly higher than in control (p < 0.001, p = 0.003, respectively). CONCLUSIONS The two materials increased the percent mean MD change of early proximal caries lesions to a similar extent, but with different spatial patterns. CLINICAL RELEVANCE Due to deeper level of GIC remineralization, the refractive index of the GIC applied enamel might be closer to sound enamel. Hence, GIC is recommended for remineralization of anterior teeth. SDF staining makes it unsuitable for use in anterior teeth; thus, it is reserved for use in posterior teeth.

Abstract
The aim of the study was to determine the efficacy of different products containing fluoride, calcium and phosphate for enamel remineralization in eroded primary teeth. A total of 90 sound primary canine teeth were randomly divided into 5 groups of 18 teeth each: 1) control (polished enamel), 2) 5% DuraShield sodium fluoride varnish, 3) 500 ppm fluoridated toothpaste, 4) casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) cream, and 5) Clinpro White varnish containing functionalized tri-calcium phosphate (fTCP). Enamel microhardness (EMH) was measured in all samples before and after demineralization and after 28 days of remineralization. Also 8 samples in groups 2 to 5 and four samples of sound and demineralized enamel were examined with atomic force microscopy (AFM). All data were analyzed with one-way ANOVA (p<0.05). Mean microhardness of demineralized enamel was significantly lower than in enamel at baseline (p<0.001). Remineralization significantly increased microharness in groups 2 to 5 compared to the control group (p<0.001). Percent EMH after remineralization with CPP-ACP was significantly higher than after fTCP (p=0.029), toothpaste (p< 0.001) or fluoride varnish (p<0.001); however, there was no significant difference between toothpaste and fluoride varnish (p=0.062). Microhardness increased more after fTCP treatment than after treatment with sodium fluoride varnish (p<0.001) or fluoridated toothpaste (p=0.045). AFM images showed that enamel roughness decreased most after treatment with fTCP, followed by CPP-ACP, toothpaste and fluoride varnish. The efficacy of CPP-ACP cream for remineralizing eroded enamel was greater than fluoride toothpaste, fluoride varnish or fTCP varnish.

Abstract
BACKGROUND The aim of this study was to investigate factors that influence dental therapists and oral health therapists (therapists) plan preventive oral health care for adolescents attending New South Wales public oral health services. METHODS A cross-sectional postal survey using two clinical vignettes was used to record the preventive care treatment plans offered by therapists working across 15 New South Wales local health districts. Data were tabulated and chi-square statistics used in the analysis. RESULTS One hundred and seventeen therapists returned questionnaires, giving a 64.6% response rate. The participants highlighted the importance of offering oral hygiene instruction (97.0%), dietary advice (95.0%) and topical fluoride applications (74.0%). Recommended home use products included fluoride toothpaste 5000 ppmF (59.0%) and casein phosphopeptide-amorphous calcium phosphate plus fluoride (CPP-ACPF) paste (57.7%). Over 50% used fissure sealants. More respondents (88%) would utilize motivational interviewing strategies for a patient with dental caries concerns; however, only 63% would use this technique for a patient in pain (p < 0.001). CONCLUSIONS Considerable variations were noted in therapists' recommendations for stabilizing and managing dental disease, suggesting a need for clinical directors to consider providing more advice to therapists on the scientific basis of preventing dental caries.

MATERIALS AND METHODS Ten freshly extracted un-erupted third molars decoronated at cement-enamel junction (CEJ) used in this study. Each decoronated tooth was sectioned to get 4 samples of enamel blocks such that 40 blocks were obtained which were then subjected to demineralization protocol and grouped as: Group 1-untreated group, Group 2-subsurface demineralization, Group 3-subsurface demineralization + 7 days CESP immersion, Group 4- subsurface demineralization + clinpro application. The samples were evaluated for X-ray fluorescence spectroscopy analysis, microhardness testing and atomic analyses using energy dispersive X-ray spectroscopy. The data were statistically analysed by using one-way ANOVA and Tukey - Kramer multiple comparison test. RESULTS X-ray Fluorescence spectroscopy shows Calcium concentration of 98% and 0.46% of phosphate. Group 4 (Clinpro) shows the highest efficacy in enhancing the remineralization followed by Group 3 (CESP). The results of atomic analyses showed that quantitative amounts of Ca weight % and P weight % is statistically greater for all the three groups except the demineralized group. CONCLUSION CESP with higher calcium content can remineralise enamel surface lesion.

Abstract
PURPOSE Hematology-oncology patients undergoing chemotherapy and hematopoietic stem cell transplantation (HSCT) recipients are at risk for oral complications which may cause significant morbidity and a potential risk of mortality. This emphasizes the importance of basic oral care prior to, during and following chemotherapy/HSCT. While scientific evidence is available to support some of the clinical practices used to manage the oral complications, expert opinion is needed to shape the current optimal protocols. METHODS This position paper was developed by members of the Oral Care Study Group, Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) and the European Society for Blood and Marrow Transplantation (EBMT) in attempt to provide guidance to the health care providers managing these patient populations. RESULTS The protocol on basic oral care outlined in this position paper is presented based on the following principles: prevention of infections, pain control, maintaining oral function, the interplay with managing oral complications of cancer treatment and improving quality of life. CONCLUSION Using these fundamental elements, we developed a protocol to assist the health care provider and present a practical approach for basic oral care. Research is warranted to provide robust scientific evidence and to enhance this clinical protocol.

Abstract
OBJECTIVE The aim of this study was to determine the effect of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) on caries progression in irradiated nasopharyngeal carcinoma (NPC) patients. METHODS Twenty-one males and three females (median age, 50 years) were randomized into two groups before radiotherapy. Subjects had at least eight teeth after oral health clearance. The test group used 0.4 % stannous fluoride gel and a crème containing 10 % CPP-ACP daily; the control group used a similar crème without CPP-ACP and otherwise identical care. Subjects applied the crème three times daily and fluoride gel once daily. Caries status, saliva and plaque parameters were measured pre-radiotherapy, at 2 weeks and 3 months post-radiotherapy. RESULTS Baseline International Caries Detection and Assessment System (ICDAS) scores were 0-1126 surfaces (93.9 %), 1-28 surfaces (2.3 %), 2-40 surfaces (3.3 %) and 3-6 surfaces (0.5 %) for the control and 0-1186 surfaces (95.6 %), 1-31 surfaces (2.5 %), 2-15 surfaces (1.2 %) and 3-8 surfaces (0.7 %) for the test group. Twenty-two subjects returned at 3 months post-radiotherapy with reduced plaque pH, salivary flow, pH and buffering capacity. Nine test and 8 control subjects developed 32 and 59 new caries lesions, respectively. Test subjects showed lower caries progression than the controls: all surfaces (OR 0.51, 95 % CI 0.17∼1.59), occlusal (OR 0.20, 95 % CI 0.03∼1.29) and smooth surfaces (OR 0.61, 95 % CI 0.16∼2.38). The difference was not statistically significant. CONCLUSION Application of CPP-ACP did not significantly reduce caries progression in NPC patients in the first 3 months after radiotherapy as compared to controls. CLINICAL RELEVANCE Adjunct use of CPP-ACP with stannous fluoride gel in irradiated NPC patients gave comparable results compared to stannous fluoride gel alone in reducing caries progression.

Abstract
To test the efficacy of two calcium phosphate pastes compared to that of fluoride toothpaste on remineralizing artificial caries in situ, this study had a double-blind crossover in situ design, involving three experimental phases of 14 days each, with an 8-day washout period between phases. Nine healthy subjects participated in the study. The subjects wore removable palatal appliances mounted with six human enamel slabs with artificial caries lesions, and in each of the experimental phases, used one of the following methods two times/day: group A, brushing with 1.0 g of Colgate Regular Flavor, followed by applying 0.25 g of Tooth Mousse Plus; group B, brushing with 0.25 g of Clinpro Tooth Crème; and group C, brushing with 1.0 g of Colgate Regular Flavor. After 14 days, the enamel slabs (54 slabs/group) were embedded in resin, sectioned and examined with a polarized-light microscope, and the lesion areas were quantified using Image-Pro Plus. All experimental groups showed a significant reduction in lesion area compared to the initial lesion area (paired t-test, P<0.001). The mean reduction in lesion area of Groups A, B and C were (0.029±0.010), (0.030±0.009) and (0.027±0.009) mm2, respectively. There were no statistical differences between groups (Kruskal–Wallis test, P>0.05). All three groups remineralized the enamel slab lesions, indicating model sensitivity to fluoride. Given the differences in usage amounts and treated regimens, Clinpro Tooth Crème provided similar benefits to the fluoride toothpaste; however, no additional benefit of Tooth Mousse Plus was observed when used in conjunction with the fluoride toothpaste.

Abstract
Phosphoproteins/phosphopeptides with clusters of acidic residues are found throughout nature, where they aid in the prevention of unwanted precipitation of solid calcium phosphates. The acidic residues, particularly phosphoserine, interact with calcium and stabilize clusters of calcium and phosphate. Saliva and milk are two examples of biological fluids that contain such phosphoprotein/phosphopeptide-stabilized calcium phosphates, and both share a similar evolutionary pathway. Saliva has been shown to have remineralization potential and is of critical importance in maintaining the mineral content of teeth in the oral environment. Milk can be enzymatically modified to release casein phosphopeptides that contain the clusters of residues that allow milk to stabilize high concentrations of calcium and phosphate. These casein phosphopeptide-stabilized amorphous calcium phosphate nanocomplexes (CPP-ACP) can stabilize even higher concentrations of calcium and phosphate than milk and can be considered a salivary biomimetic, since they share many similarities to statherin. The mechanisms of action and the growing body of scientific evidence that supports the use of CPP-ACP to augment fluoride in inhibiting demineralization and enhancing the remineralization of white-spot lesions are reviewed.

Abstract
Caseinophosphopeptides (CPPs), bioactive peptides released from caseins, have the ability to enhance bivalent mineral solubility. This is relevant to numerous biological functions in the oral cavity (promotion of tooth enamel remineralisation, prevention of demineralisation and buffering of plaque pH). Therefore, CPPs may play a positive role as prophylactic agents for caries, enamel erosion and regression of white spot lesions. Most in vitro and in situ studies demonstrate strong evidence for the bioactivity of CPPs in the oral cavity. Nevertheless, relatively little is known concerning their use as adjuvants for oral health and more particularly regarding their long-term effects on oral health.

Abstract
The aim of this study was to assess the effect of chewing gum containing phosphoryl oligosaccharides of calcium (POs-Ca) and a low concentration of fluoride (F) on the hardness of enamel subsurface lesions, utilizing a double-blind, randomized, and controlled in situ model. Fifteen individuals wore removable lingual appliances with 3 bovine-enamel insets containing subsurface demineralized lesions. Three times a day for 14 days, they chewed one of the 3 chewing gums (placebo, POs-Ca, POs-Ca+F). After the treatment period, cross-sectional mineral content, nanoindentation hardness, and fluoride ion mapping by time-of-flight secondary ion mass spectrometry (TOF-SIMS) were evaluated. Although there were no statistical differences in overall mineral content and hardness recovery rates between POs-Ca and POs-Ca+F subsurface lesions (p > 0.05), nanoindentation at 1-μm distance increments from the surface showed statistical differences in hardness recovery rate between POs-Ca and POs-Ca+F in the superficial 20-μm region (p < 0.05). Fluoride mapping revealed distribution of the ion up to 20 μm from the surface in the POs-Ca+F group. Nanoindentation and TOF-SIMS results highlighted the benefits of bioavailability of fluoride ion on reinforcement of the superficial zone of subsurface lesions in situ (NCT01377493).
