RESUMO

The aim of this study was to investigate how Brazilian dentists perceive and manage dentin hypersensitivity (DH) in their clinical routine. A 13-item questionnaire-based survey was developed and sent electronically to a convenience sample of dentists. The questionnaire assessed the personal and dental practice characteristics of the sample, the occurrence of DH in their daily clinical practice, and management strategies. The data were analyzed descriptively and together with the chi-square test (a = 0.05). A total of 353 responses were obtained from September 2017 to March 2018. Of all the respondents, 62% were females, 49.9% reported fewer than five years of dental practice, and 70.5% were self-identified as private practitioners. Most of the dentists reported an estimated frequency (30-60%) of patients with DH in their practice. The most frequently cited (91.79%) trigger of DH was air blast and/or scratching with a probe. The first-choice strategy to manage DH was a dentin desensitizer (48.16%). The number of years in clinical practice did not influence DH relapse frequency (p = 0.76) significantly, or consider DH treatment as a problem (p = 0.22). The present findings indicate that, regardless of clinical experience, dentists in Brazil still consider DH management a challenge in their daily dental practice. In addition, the results suggest that guidelines should be developed to disseminate the available knowledge regarding this condition in ways that may influence decision-making processes among practitioners.

RESUMO

Background: The aims of this study are to present sociodemographic and familial characteristics, clinical and systemic findings, dental treatment needs, and concomitant dental anomalies in patients with amelogenesis imperfecta (AI) and to evaluate time-varying conditions in these long-term follow-up patients. Materials and Methods: Records of patients with AI who were examined in the Department of Pediatric Dentistry between 1999 and 2017 were reviewed. Information about sociodemographic characteristics, history of AI and consanguinity in family, systemic conditions, reasons for referral to the clinic, oral hygiene habits and gingival health, occlusion findings, and performed treatments were gathered. Dental anomalies in radiographs were also evaluated. Baseline and final situations of the patients were assessed. Statistical analyses were performed. Results: Of 75 patients aged 3-15 years with follow-ups up to 12 years, 34 had AI in their families and 15 were born from consanguineous marriages. Nephrocalcinosis has been observed in 5 patients. Main reasons for referral to the clinic were related to esthetic and hypersensitivity concerns. Twenty-two patients had gingivitis, and during follow-up process, gingival problems could not be completely prevented due to poor oral hygiene habits. Vertical dimension loss, open-bite, and cross-bite were seen in 16, 15, and 10 patients, respectively. Of the patients, 63% experienced restorative, 33% stainless steel crown, 17% endodontic, 8% prosthetic treatments, and 24% had retreatment needs. Concomitant dental anomalies were dens invaginatus, taurodontism, ectopic eruption, delayed eruption, hypodontia, and pulpal calcification. Conclusion: Early diagnosis and interventions considering the time-varying conditions with long-term follow-ups provide significant improvements in clinical maintenance of patients with AI.

RESUMO

The aim of this study is to develop a decision-making path for the management of non-carious cervical lesions (NCCLs) associated with or without dentin hypersensitivity (DH) This will allow to limit or delay invasive approaches identifying the causes that produced them. The need for this review is because there are no clear guidelines in the current literature for the treatment of NCCLs. Usually, the selection of the best therapy option is postponed to clinical judgment which can be influenced by a patient's demands (aesthetic, symptomatologic reasons or worsening of pre-existing NCCL). To establish a therapeutic plan the young dentist should be able to distinguish the NCCLs that need to be monitored over time from those in need of early treatment. Indeed, the experience of the dentist and the compliance of the patient play a decisive role for the success of the therapy.

RESUMO

Dentin hypersensitivity is a common oral condition with a high prevalence rate. As part of the Chinese dental clinicians have some uncertainties on the prevention, diagnosis and treatment of dentin hypersensitivity, a task force was formed under the supervision of the Section of Preventive Dentistry, Chinese Association of Stomatology to develop the present clinical guide on diagnosis and management of dentin hypersensitivity according to the evidence-based dentistry. The evidence is based on systematic and narrative reviews published during the past 10 years (2009-2018) in the Medline database. The present guildlines consist of the definition, epidemiology, etiology and mechanisms, contributing factors, diagnosis and prevention of dentin hypersensitivity, the clinical treatment of dentin hypersensitivity was also recommened.

RESUMO

To synthesize Nano eggshell-titanium-dioxide (EB@TiO2) biocomposite and to evaluate its effectiveness in occluding opened dentine tubules. EB@TiO2 was synthesized and characterized using X-ray diffraction (XRD), and Transmission Electron Microscope (TEM). Sixteen simulated bovine dentine discs were prepared and randomly assigned into four groups according to the following treatment (n = 4): Group 1: No treatment; Group 2: eggshell powder; Group 3: EB@TiO2; Group 4: Sensodyne. These were then agitated in a solution of 1g powder and 40mL water for 3hours. Thereafter, each dentine discs from the respective groups were post-treated for 5 min with 2wt% citric acid to test their acid resistant characteristics. Scanning Electron Microscope (SEM) was used to observe the effectiveness of occluded dentine pre-and post-treatment. The cytotoxicity of the synthesized EB@TiO2 was tested using NIH 3T3 assay. ANOVA was used to evaluate the mean values of the occluded area ratio and the data of MTS assay. This was followed by a multi-comparison test with Bonferroni correction (α = .05). The XRD confirmed that EB@TiO2 was successfully modified through ball-milling. The TEM revealed the presence of both spherical and irregular particle shape powders. The SEM result showed that EB@TiO2 could effectively occlude open dentine tubules. Equally, the result demonstrated that EB@TiO2 exhibited the highest acid resistant stability post-treatment. NIH 3T3 assay identified that EB@TiO2 had little effect on the NIH 3T3 cell line even at the highest concentration of 100µg/ml. This study suggests that the application of EB@TiO2 effectively occluded dentine tubules and the occlusion showed a high acid resistant stability.

RESUMO

OBJECTIVES: The aim of the present study was to compare the clinical efficacy of diode laser and Er,Cr:YSGG lasers in the treatment of dentin hypersensitivity. MATERIALS AND METHODS: Thirty-four teeth from 17 patients with dentin hypersensitivity were divided into two groups. In group D, the teeth were irradiated with diode laser beams with a wavelength of 940 nm for 1 min, and in group E, the teeth were irradiated with Er,Cr:YSGG laser beams with a wavelength of 2780 nm and a pulse width of 140-200 µs. Treatments with laser beams were carried out in 1 session. Sensitivity was assessed with air spray and a dental explorer. Pain severity was measured with the use of visual analog scale (VAS) before and after laser application. RESULTS: A decrease in dentin hypersensitivity was observed in both groups immediately, 1 week, and 1 month after laser irradiation. Statistically significant differences were found between the two groups in dentin hypersensitivity severity only 1 month after laser application. The decrease in dentin hypersensitivity by Er,Cr:YSGG laser was significantly higher than that by diode laser at this time interval. CONCLUSION: The decrease in dentin hypersensitivity after application of Er,Cr:YSGG laser was significantly higher than that after the application of diode laser at 1-month postoperative interval. CLINICAL RELEVANCE: Er,Cr:YSGG laser is a better choice than diode laser for the treatment of dentin hypersensitivity in the short term.

RESUMO

AIM: This double-blind, placebo-controlled, randomized clinical trial evaluated the effectiveness of Nd:YAG laser and a calcium sodium phosphosilicate-containing paste (NovaMin®) in the treatment of cervical dentin hypersensitivity (CDH). MATERIALS AND METHODS: Seventy patients were randomly allocated into the following experimental groups: control-placebo, calcium sodium phosphosilicate paste (NovaMin®), and Nd:YAG laser (1 W, 10 Hz, 85 J/cm2). Pain was evaluated by means of a visual analog pain scale (VAS) after evaporative stimulation with a jet of air and tactile stimulation with an exploratory probe, before treatment (baseline) and after 5 min, 1week, and 4 weeks. When patients presented more than one tooth with CDH, the mean of the values obtained was calculated. Irradiation with Nd:YAG laser was performed twice in the mesial-distal and twice in the occlusal-gingival direction. The NovaMin®-containing paste was applied with a rubber cup at low speed for 60 s. Patients of the placebo group received simulations of the two treatments. As the data presented normal distribution, the two-way ANOVA repeated measures test was used. RESULTS: In all the experimental times, reduction in pain was demonstrated in comparison with baseline for all treatments (p < 0.05); however, there was no difference among the experimental groups in any of the time intervals evaluated (p > 0.05). CONCLUSION: All treatments were equally effective in reducing the pain of CDH. CLINICAL RELEVANCE: Nd:YAG laser irradiation and the calcium sodium phosphosilicate paste could reduce the symptoms of CDH; thus, they stand out as viable alternatives for the treatment of this condition.

RESUMO

OBJECTIVES: To evaluate the effect of photobiomodulation with low-level laser therapy (PBM-LLLT) combined with 5% potassium nitrate (KNO3) on controlling tooth sensitivity (TS) after in-office tooth bleaching. MATERIALS AND METHODS: Fifty volunteers were selected based on the inclusion and exclusion criteria and were randomly allocated into four groups: G1 (control): placebo gel application, 35% hydrogen peroxide bleaching (HP35) and mock PBM-LLLT without light emission; G2: placebo gel application, bleaching with HP35 and PBM-LLLT; G3: application of KNO3, bleaching with HP35 and mock PBM-LLLT; and G4: application of KNO3, bleaching with HP35 and PBM-LLLT. A pain assessment questionnaire was used to evaluate TS during the 21 days of treatment. The Friedman test was used for intragroup analysis, and the Wilcoxon and Mann-Whitney tests were used for intergroup comparisons. RESULTS: The intragroup evaluation showed significant differences among the evaluation times in all groups (p ≤ 0.05). The highest pain sensitivity levels were recorded on the 1st, 8th, and 15th days. In G1, TS manifested for up to 3 days after each bleaching session, while G2, G3, and G4 presented TS only on the days of the bleaching sessions. Intergroup analysis showed that TS manifestation differed significantly between G1 and the other groups (p ≤ 0.05) but did not differ significantly among G2, G3, and G4 (p ≥ 0.05). CONCLUSION: PBM-LLLT and KNO3 are effective at reducing pain sensitivity after tooth bleaching, but no synergistic effect between these treatments was observed for the different evaluation periods. CLINICAL RELEVANCE: The effect of PBM-LLLT combined with KNO3 on post-bleaching tooth sensitivity is similar to their individual use alone.

RESUMO

La exposición de dentina radicular asociada a una recesión gingival puede producir dolor ante distintos estímulos, situación que puede difi cultar la vida cotidiana de los pacientes que lo padecen, además de presentar complicaciones estéticas que pueden afectar la autoestima. La hipersensibilidad dentinaria tiene una etiología asociada a múltiples factores, siendo el principal factor de riesgo la recesión gingival, situación clínica común que se observa en gran parte de la población. El propósito de esta revisión es reunir distintos conceptos que expliquen la asociación que mantienen estas dos patologías, sus etiologías, el cuadro clínico que presenta la hipersensibilidad dentinaria para poder realizar un diagnóstico diferencial y las distintas opciones de tratamiento para realizar un adecuado manejo de esta condición que incluyen desde recursos terapéuticos que buscan resolver la sintomatología hasta procedimientos quirúrgicos que resultan más invasivos y que se enfocan en tratar el factor predisponente como es la recesión gingival misma (AU)

RESUMO

PURPOSE: The purpose of this study was to explore the effect of Nd:Yap laser combined with composite resin filling on reducing hypersensitivity of dental wedge-shaped defect. METHODS: Seventy cases, 144 teeth with sensitive wedge-shaped defects were selected. The patients were randomly divided into 2 groups and treated as below: 35 cases, 74 teeth in group A were treated with composite resin directly; 35 cases, 70 teeth in group B were treated with Nd:Yap laser combined with composite resin. After treatment, the effective rates under clinical examination standard (immediately, 1, 3 and 6 months after treatment) in both groups were collected and statistically analysed with SPSS 13.0 software package. RESULTS: In group A, one and 2 teeth fillings fell off 3 months and 6 months after treatment,respectively. In group B, one and 1 tooth fillings fell off 3 months and 6 months after operation. There was no significant difference between the two groups (P>0.05). The effective rates of desensitization were 95.71%,91.43%,87.14% and 81.43% in group B, respectively, which were significantly higher than those in group A (82.43%,78.38%,72.97% and 64.86%)(P<0.05). CONCLUSIONS: Nd:Yap laser combined with composite resin filling can treat sensitive wedge-shaped defect effectively and improve the symptoms of tooth sensitivity significantly.

RESUMO

BACKGROUND: Dentine hypersensitivity is especially frequent in patients with pronounced periodontal attachment loss. Aim of the treatment is an obstruction of the dentine tubules in order to inhibit liquid or osmotic motion, which is considered as trigger for pain sensations. Novel approaches aim for obstruction by calcium phosphate compounds in order to rely on biocompatible compounds. It was the aim of the study to optically investigate the morphology and to assess the fluid permeability of treated dentine surfaces. METHODS: Dentine discs were pretreated in an ultrasonic bath with 17% EDTA to clean the lumina of the dentine tubules. Samples of group A remained untreated while Seal&Protect® as a conventional desensitizer was applied for group B and DentinoCer in group C. Discs were mounted into a pulp fluid simulator (PFS) with a methylene blue solution in order to create a flow pressure of 0.5 bar. Over 12 d, discs were exposed three times per day to 0.1 M nonsaturated lactic acid. At baseline and after 2, 8 and 12 d samples were removed from PFS and prepared for SEM analysis. Tubule obstruction was assessed quantitatively using Olley scores and by qualitative description of the surface. Absorption spectrometry was used to assess the concentration of leaked methylene blue outside the samples in order to estimate dentine permeability. RESULTS: Untreated discs showed clean lumina of all tubules at all time points and magnifications. From day 2 onwards dentine showed exposed collagene fibers due to acid exposition. Seal&Protect® initially showed homogenous dentine surface coverage that got a more granulomatous aspect in the course of treatment time. Few samples showed sporadic tubules with open lumen at day 8 and 12. Group C showed samples with a homogeneous, even surface. Narrow slits in the superficial layer are visible from day 4 on, but the dentine surface remained invisible and dentine tubules were closed till the end of the investigation period. CONCLUSION: Over 12 d of lactid acid exposure, samples showed complete coverage of the dentine tubules in the chosen in-vitro-model when treated with Seal&Protect® or DentinoCer.

RESUMO

PURPOSE: The aim of this study was to compare the effect of Nd:YAG laser to that of a new varnish: MI Varnish with RECALDENT (GC), for the treatment of dentin hypersensitivity, with a follow-up of 6 months. Dentinal hypersensitivity was evaluated using a new thermal test never before used on dental tissue. MATERIALS AND METHODS: A split-mouth design was used where teeth on one side received the same type of treatment. Twelve patients suffering from dentin hypersensitivity were chosen. Fifty-four teeth were divided into 27 pairs. Twenty-seven teeth received the Nd:YAG laser treatment, and the 27 contralateral teeth received MI Varnish application. Five parameters were measured, and the measurements were taken before treatment at baseline (T0), after 1 week (T1), 1 month (T2), 3 months (T3), and 6 months (T4) of the application. Air stimulation to obtain the Schiff air score, the score of discomfort according to the visual analog scale (VAS), the tactile score, and the thermal test that determines the minimum cold-stimulating temperature and the maximum heat-stimulating temperature were all used to assess sensitivity. Statistical analyses of the data were performed, and the significance level was set at p ≤ 0.05. Exact Fisher tests and Chi-Square tests were conducted to compare percentages. RESULTS: There was a clear decrease in dentin hypersensitivity for both treatments (Nd:YAG laser and MI Varnish) especially between baseline and 1 week, with maintenance of this state through the 6-month follow-up period. The difference between the two treatments was not significant, comparing, over time, the Schiff air score, the thermal test, and the VAS; however, the tactile score was significantly improved 6 months after the application of MI Varnish compared to the laser (p = 0.05). CONCLUSION: There was no significant difference between the two treatments, Nd:YAG laser and MI Varnish. Both treatments were effective and reduced dentin hypersensitivity immediately after treatment up to 6 months.

RESUMO

This study aimed to develop of a rapid and effective method to occlude dentinal tubules using carboxymethyl chitosan and lysozyme (CMC/LYZ) nanogels with encapsulated amorphous calcium phosphate (ACP) based on the transformation of ACP to HAP. In this work, CMC/LYZ was used to stabilize ACP and form CMC/LYZ-ACP nanogels, and then the nanogel-encapsulated ACP was applied to exposed dentinal tubule surfaces. The morphology of the nanogels was examined by transmission electron microscopy (TEM). Distribution and quantity of elements in CMC/LYZ-ACP nanogels were determined by element mapping and energy dispersive X-Ray spectroscopy (EDX). Scanning electron microscopy (SEM) images, XRD measurements and nanoindentation were applied to check the efficacy of tubular occlusion. TEM revealed that CMC/LYZ-ACP nanogels were spherical dense gel particles with size approximately 50-500 nm. Element mapping and EDX indicated that C, N, O, Ca, P, and S in the microspheres are thoroughly represented. SEM images shows that the thickness of the coating layer was approximately 1-2 µm and the depth to which the mineralized substance enters the dentinal tubule was approximately 4-8 µm. XRD measurements and nanoindentation indicated that the occluding mineralized substance observed were similar to nature dentin. CMC can form spherical dense nanogels loaded with ACP under the participation of lysozyme. The CMC/LYZ-ACP nanogels could increase the dentinal tubule occluding effectiveness. These results indicated that finding and developing novel nanomaterials of CMC/LYZ-ACP would be an effective strategy for the treatment of dentin hypersensitivity.

RESUMO

PURPOSE: To assess the effectiveness of four in-office therapies used for the treatment of dentin hypersensitiviy (DH) after one single application. MATERIALS AND METHODS: A randomised, controlled, split-mouth clinical trial was designed to evaluate the following treatments: 5% sodium fluoride varnish (positive control); 3% potassium oxalate; two-step self-etching adhesive; high power diode laser. Nineteen patients were selected and one tooth per quadrant was included in the study. After evaporative stimulation, pain was quantified by the Visual Analog Scale (VAS) at baseline, immediately after treatment, and after 15, 30 and 60 days. RESULTS: Compared to the baseline values, fluoride varnish (p = 0.00) and potassium oxalate (p = 0.00) presented an immediate desensitising effect that remained constant at 15, 30 and 60 days. The high-power diode laser presented significant reduction in VAS scores after 15 days (p = 0.00), while in the self-etching adhesive group, a significant reduction in VAS scores was observed only after 60 days (p = 0.03). The change in VAS ([VAS x days] - VAS baseline) differed among the groups immediately after treatment, being higher in the fluoride varnish and lower in the adhesive groups, but no statistically significant difference was found at time intervals of 15, 30 and 60 days. CONCLUSION: When an immediate desensitising effect is desired after one single application, fluoride varnish and potassium oxalate should be used. High-power diode laser and self-etching adhesive may not be clinically considered an appropriate desensitising therapy after one single application.

RESUMO

OBJECTIVES: To examine dentin hypersensitivity (DH) at multiple time points over a 14-day period in participants who brushed twice daily with a 0.454% SnF2 dentifrice (Test) compared to a 0.76% sodium monofluorophosphate dentifrice with no known anti-sensitivity properties (Control). METHODS: This was a two-week, single-center, randomized, controlled, examiner-blind, two-treatment, parallel-group study in healthy participants with DH. The sensitivity of two selected test teeth and of all sensitive teeth was assessed at baseline and after one, three, seven, 10, and 14 days' treatment in response to evaporative (air) Schiff sensitivity score and visual analogue scale [VAS]) and tactile (tactile threshold) stimuli. DH was also monitored using a shortened version of the Dentin Hypersensitivity Experience Questionnaire (DHEQ) and a single "Tooth Sensitivity Question" (TSQ). RESULTS: Both groups had mean Schiff sensitivity scores that were statistically significantly improved from baseline on all days for the two test teeth and all qualifying teeth (p < 0.0001). There was a statistically significant difference between the dentifrices at Day 1 only, in favor of the Control dentifrice, for the two test teeth (0.28 [95% confidence intervals 0.03,0.53] p = 0.0282) or all qualifying teeth (0.17 [0.02,0.32] p = 0.0273). For tactile threshold, both dentifrices were statistically significantly improved from baseline from Day 3 onwards, with the Test dentifrice showing an improvement at Day 1 (p < 0.05). There were no significant statistical between-treatment differences at any time point. DHEQ questions revealed most participants experienced "sensitivity," "twinging," and "pain," with cold stimuli rated as the highest DH-eliciting. DHEQ Section 1 rating scores improved with the Test dentifrice, but not significantly statistically. DHEQ Section 2 scores statistically significantly improved with both dentifrices (p < 0.0002) with no differences between them. TSQ scores for both groups reduced over the time period. Both dentifrices were generally well-tolerated. CONCLUSIONS: In this study, use of both the Test and Control dentifrices led to DH relief with few statistically significant differences between them. The DHEQ and TSQ showed a reduction of pain during the study period, but there was still a high level of discomfort. Further research on short term relief of DH is required.

RESUMO

Despite nearly a century of research, the treatment of cervical dentinal hypersensitivity (DH) remains challenging. This case report discusses the indications for different approaches to the treatment of DH in a single patient; the chosen alternatives took into account the different degrees of tooth wear and levels of pain at different sites. A 31-year-old woman reported DH in the maxillary right canine and first premolar and the maxillary left lateral incisor and canine in response to thermal, tactile, and osmotic stimuli. Clinical examination revealed that the teeth on the right side presented noncarious cervical lesions deeper than 1 mm, while the teeth on the left side presented only minimal wear. Therefore, the right canine and premolar were restored with composite resin to create a mechanical barrier against stimuli and reestablish form, function, and esthetics. Prior to restoration, the teeth on the right side were irradiated with a low-power laser (808 nm, 100 mW, 1.1 J/point, 10 seconds), which was applied in a single session at 2 locations on each tooth. In contrast, the left lateral incisor and canine were irradiated in 3 sessions with the low-power laser, which reduces pain levels and depolarizes nerve fibers by means of cell biomodulation, and received no restorations. A visual analog scale (0.0-10.0) was used to record the patient's pain, and it was found that pain levels for the restored teeth decreased from 9.4 initially to 0.0 immediately after restoration, and pain levels for the irradiated teeth decreased from 5.4 initially to 2.0 after 3 sessions. After 6 months of clinical evaluation, both sets of teeth showed scores of 0.0 (no pain). Based on the results presented, it can be concluded that both treatments provided satisfactory outcomes when applied for the appropriate indication.

RESUMO

Aim: The aim of this clinical study was to determine and compare the efficiency of the glutaraldehyde-containing agent (GCA), Nd:YAG, Er,Cr:YSGG lasers, and the combination of them on the dentin hypersensitivity (DH) treatment. Subjects and Methods: This study was performed with the participation of 17 healthy adult patients having 100 teeth with DH; the patients were randomly divided into five groups according to the treatment protocol: (1) application of GCA on sensitive teeth, (2) Nd:YAG laser (1 W/cm2, 10 Hz) irradiation on sensitive teeth, (3) application of GCA on sensitive teeth and then Nd:YAG laser irradiation, (4) Er,Cr:YSGG laser (0.25 W/cm2, 20 Hz) irradiation on sensitive teeth, (5) application of GCA on sensitive teeth and then Er,Cr:YSGG laser irradiation. Sensitivity levels were assessed by the Yeaple probe on the buccal surfaces of the teeth at a force setting of 10 g. Measurements were performed for 30 min, after 7, 90, and 180 days of the therapy to assess the effects of desensitization. The evaluations were analyzed using the one-way analysis of variance and repeated measurement test (P < 0.05). Results: After sessions, DH was significantly reduced in all groups at each measurement point. The Er,Cr:YSGG laser with or without GCA application were the most effective ones in DH treatment (P < 0.05). Comparison of the treatment regimens demonstrated that the scores achieved with the Yeaple probe were not significantly higher for the Nd:YAG laser groups than the GCA alone group. Conclusions: This clinical study shows that the Er,Cr:YSGG laser have promising potential for the treatment of DH.

RESUMO

PURPOSE: Human tooth enamel consists mostly of minerals, primarily hydroxyapatite, Ca10(PO4)6(OH)2, and thus synthetic hydroxyapatite can be used as a biomimetic oral care agent. This review describes the synthesis and characterization of hydroxyapatite from a chemist's perspective and provides an overview of its current use in oral care, with a focus on dentin hypersensitivity, caries, biofilm management, erosion, and enamel lesions. SOURCES: Reviews and original research papers published in English and German were included. RESULTS: The efficiency of synthetic hydroxyapatite in occluding open dentin tubules, resulting in a protection for sensitive teeth, has been well documented in a number of clinical studies. The first corresponding studies on caries, biofilm management and erosion have provided evidence for a positive effect of hydroxyapatite either as a main or synergistic agent in oral care products. However, more in situ and in vivo studies are needed due to the complexity of the oral milieu and to further clarify existing results. CONCLUSIONS: Due to its biocompatibility and similarity to biologically formed hydroxyapatite in natural tooth enamel, synthetic hydroxyapatite is a promising biomimetic oral care ingredient that may extend the scope of preventive dentistry.

RESUMO

OBJECTIVE: The aim of this review is to conduct a systematic review and meta-analysis comparing the effectiveness of in-home or in-office treatments for dentin hypersensitivity. MATERIALS AND METHODS: An electronic search without restriction on dates or languages was performed in four electronic databases until March 2017. In addition, hand-searches in regular journals and in the gray literature were also conducted. To develop the search strategy, clinical questions were formulated using the PICOS method. Eligibility criteria included randomized clinical trials (RCTs) that compared the effectiveness of different agents for the treatment of dentin hypersensitivity through chemical occlusion, physical occlusion, nerve desensitization, or photobiomodulation (low-level light therapy). This systematic review was registered in PROSPERO under number CRD42016039394. RESULTS: Twenty-five RCTs (16 parallel; 9 split-mouth), published from 1992 to 2016, were included. The results of the meta-analysis showed that in-office subgroups treated with chemical or physical occlusion of dentin tubules and nerve desensitization had a statistically significant difference from placebo, with P < 0.00001, P < 0.00001, and P = 0.02, respectively. For in-home treatments, the results of the meta-analysis showed that only those subgroups treated with chemical occlusion of dentin tubules and nerve desensitization exhibited a statistically significant difference from placebo, with P < 0.00001 and P = 0.03, respectively. CONCLUSIONS: The results of pairwise meta-analysis suggest that among in-office treatments, dentinal tubule occlusion (whether chemical or physical) and nerve desensitization provide the best outcomes for treatment of dentin hypersensitivity. For in-home treatments, only chemical occlusion of dentin tubules and nerve desensitization showed a greater treatment efficacy than placebo and the difference was statistically significant.

RESUMO

Sodium bicarbonate (ie, baking soda) can be used as an adjunct to surgical periodontal therapy to reduce dentin hypersensitivity (DH). Sodium bicarbonate mouthwash has numerous appealing attributes, including high availability, low cost, low abrasivity, water solubility, buffering capability, and, in high concentrations, antimicrobial properties. It is also safe to use. The primary underlying cause of DH is open dentinal tubules from loss of either cementum or enamel. The aim of this in vitro study was to evaluate, through scanning electron microscopic examination, the effect of sodium bicarbonate on dentinal tubule occlusion and compare it with that of fluoridated mouthwash.
