RESUMO

PURPOSE: To review and assess the literature on in vitro studies evaluating tooth bleaching efficacy considering the use of a negative control, type of tooth substrate, storage medium, color evaluation methods, and evaluation time points. METHODS: The following databases were searched: PubMed (MEDLINE), Web of Science. Search used Medical Subject Headings (MeSH) in PubMed in addition to free text. The following limits were applied: English, articles published between January 1989 and October 2017. Additional free text key terms included: in vitro, tooth bleaching, placebo, negative control, overall CIELAB color change (ΔE*ab), change in shade guide units (ΔSGU), tooth color stabilization, evaluation time points, bovine teeth, and staining. Search was repeated in Web of Science but no additional articles were identified. A total of 11 studies were included for qualitative and quantitative analysis. RESULTS: The meta-analysis of nine included studies that reported ΔE*ab values, revealed that the NC statistically exceeded the perceptibility threshold (PT) of 1.2 (P< 0.05). The estimate was 2.872 with lower and upper bounds of 1.955 and 3.790, respectively. CLINICAL SIGNIFICANCE: Randomized controlled trials are gold standards to evaluate bleaching efficacy of different materials. However, in vitro studies offer a way to screen for potential bleaching efficacy. It is vital to determine an appropriate cut-off value for determining bleaching efficacy in vitro and further apply for clinical relevance.

RESUMO

Noncarious cervical lesions (NCCLs) involve the loss of hard tissue from the cervical areas of teeth through processes unrelated to caries. NCCLs are nowadays a common pathology caused by changes in lifestyle and diet. The prevalence and severity of cervical wear increase with age. It is generally accepted that the lesions are not generated by a single factor but result from a combination of factors. Among the factors proposed to be related to the formation and progression of NCCLs are biocorrosion (erosion), friction (abrasion), and possibly occlusal stress (abfraction). The clinical appearance of NCCLs can vary depending on the type and severity of the etiologic factors involved. Practitioners should follow a checklist to achieve an accurate diagnosis of the etiology of multifactorial NCCLs. The successful prevention and management of NCCLs require an understanding of the etiology and risk factors, including how these change over time in individual patients. The decision to monitor NCCLs rather than intervene should be based on the progression of the lesions and how they compromise tooth vitality, function, and esthetics. Treatment options include techniques to alleviate dentin hypersensitivity and the placement of an adhesive restoration, eventually in combination with a root coverage surgical procedure. An adhesive restoration is considered the last treatment option for NCCLs. Based on their excellent esthetic properties and good clinical performance, there is a general indication to place composite restorations for NCCLs. The clinical performance of these restorations is highly product-dependent, particularly regarding the adhesive system used. The type of composite material seems to have no significant influence on the clinical performance of NCCL restorations in clinical trials. It is much more important that the operator carries out the clinical procedure correctly. Marginal degradation is frequently seen during aging. Yearly maintenance with the eventual repolishing of the restoration margins will lengthen the lifespan of the restorations.

RESUMO

The objective of this study was to determine whether collagen matrix (CM) is an alternative to connective tissue graft technique (CTG) in the treatment of multiple gingival recessions (GR). The indication of CM for the treatment of multiple GR is not yet clear. More studies are needed to better understand this treatment modality, as an alternative to CTG. In this single-blind, split-mouth randomized clinical trial, fifteen patients with multiple Miller class I upper GR were selected and randomly assigned to control group (CTG) or test group (CM). Root coverage (RC) and patient-centered outcomes were evaluated at baseline and after 3, 6, and 12 months. A total of 82 GRs were treated. There was no significant difference regarding GR depth (GRD, primary outcome) between CTG (0.5 ± 0.9 mm) and CM groups (0.6 ± 1.0 mm) (p = 0.225). Percentage of RC was 82.14% in CTG and 77.7% in CM. Both groups demonstrated a gain in keratinized tissue width at 12 months (p < 0.05). Dentine hypersensitivity was effectively reduced in both groups. Postoperative pain was significantly higher in the CTG (p = 0.001). Esthetic satisfaction was high for both groups, with no significant difference (p > 0.05) between groups. After 12 months, both surgical treatments were able to promote RC, and GRD was similar in both CTG and CM groups.

RESUMO

OBJECTIVES: This study aimed to evaluate the desensitizing effect of a prefilled disposable tray containing potassium nitrate and fluoride on the self-reported tooth sensitivity (TS) and the bleaching efficacy of 40% hydrogen peroxide bleaching agent used for in-office bleaching in comparison with potassium nitrate and fluoride gel applied in a conventional-delivered tray system in an equivalence clinical trial. METHODS AND MATERIALS: Seventy-eight patients, with a right maxillary canine darker than A3, were selected for this single-blind (evaluators), randomized clinical trial. Teeth were bleached in two sessions with a one-week interval in between. Before in-office bleaching, the prefilled disposable tray or conventional tray containing potassium nitrate and fluoride was used for 15 minutes. Subsequently, the bleaching agent was applied in two 20-minute applications (per the manufacturer's directions) in each session. The color change was evaluated by subjective (Vita Classical and Vita Bleachedguide) and objective (Easyshade Advance Spectrophotometer) methods at baseline and 30 days after the first bleaching session. TS was recorded for up to 48 hours using a 0-10 visual analog scale. The absolute risk was evaluated by chi-square test, while the intensity of TS was evaluated by McNemar test (α=0.05). Color change in shade guide units and ΔE was analyzed by Student t-test for independent samples (α=0.05). RESULTS: Significant whitening was observed in both groups after 30 days of clinical evaluation. The use of different methods of desensitizer in a tray did not influence the absolute risk and intensity of TS (p>0.05), although a tendency of lower risk of TS with the prefilled disposable tray containing potassium nitrate and fluoride was observed. CONCLUSION: The use of a prefilled disposable tray containing potassium nitrate and fluoride before the application of the in-office bleaching product did not affect the whitening degree and decreased self-reported TS when compared with a conventional-delivered tray system.

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

OBJECTIVES: This randomized triple-blind clinical trial, split-mouth design, evaluated the application effect of the desensitizing gel before and after in-office bleaching on tooth sensitivity. MATERIALS AND METHODS: In one group, the desensitizing gel was applied for 10 min before the bleaching with 35% hydrogen peroxide, and then application of placebo gel after (n = 90). In the other group, the desensitizing gel was applied before and after the bleaching procedure for 10 min (n = 90). The primary outcome was pain intensity assessed with a numeric rating scale and a visual analog scale. Color was evaluated by means of a digital spectrophotometer and a shade guides. RESULTS: The proportion of patients that experienced pain in the side of before application was 90% (95% CI 82 to 94.6%), while the side of before and after was 93% (95% CI 86.2 to 96.9%), without significant difference between groups (OR = 0.25; 95% CI 0.005 to 2.52; p = 0.37). Pain was correlated in both groups, for the NRS scale (p < 0.0001) and the VAS scale (p < 0.0001) in all assessment periods. Significant whitening was detected, and no significant difference of color change was observed between groups (p > 0.45). CONCLUSIONS: The application of the desensitizing agent did not influence the effectiveness of bleaching, but it was not efficient in reducing the sensitivity, when applied before the procedure, or before and after. CLINICAL RELEVANCE: The use of a desensitizing gel before or after in-office bleaching does not reduce incidence or intensity of tooth sensitivity.

RESUMO

PURPOSE: The aims of this ex vivo study were to evaluate the effectiveness of the Nd:YAP laser in the treatment of dentin hypersensitivity, to compare the temperature rise during laser irradiation at three different dentine thicknesses, and to analyse the composition of the dentine-lased surface. METHODS: A total of 33 teeth were used in this study. For scanning electron microscopy (SEM) observation, 24 teeth were transversely sectioned and divided into 4 groups: group A was irrigated with EDTA; group B was irradiated by Nd:YAP laser with 180 mJ energy/per pulse, 0.9 W average power, and 5 Hz frequency (power density [PD] = 229 W/cm2); group C was irradiated by Nd:YAP laser with 280 mJ energy/pulse, 1.4 W average power, and 5 Hz frequency (PD = 356 W/cm2); and group D was irradiated by Nd:YAP with 360 mJ energy/pulse, 1.8 W average power, and 5 Hz frequency (PD = 458 W/cm2). Energy-dispersive spectroscopy (EDS) analysis was performed on the same teeth evaluated for SEM observations. For temperature increase evaluation performed with thermocouples, 9 teeth were transversely sectioned at 3 different thicknesses (3 for each group) of 1, 2, and 3 mm. RESULTS: Statistical analysis showed significant changes in the diameter of the dentinal tubule orifices among all groups; EDS did not show modification of the Ca/P ratio. Temperature increase under irradiation exceeded 5.5 °C only in the group D samples. CONCLUSIONS: This ex vivo study, based on temperature recording, SEM observation, and EDS analysis, demonstrated that Nd:YAP laser at a PD of 356 W/cm2, corresponding to an average power of 1.4 W, defines the best treatment for dentine hypersensitivity in terms of compromise between efficacy of the treatment and safety of the pulp.

RESUMO

BACKGROUND: Dentine hypersensitivity is a frequent oral complaint that is usually associated with several factors including diet and oral hygiene practices. OBJECTIVE: The aim of this study was to assess the prevalence, severity and correlates of dentine hypersensitivity and dentine exposure-related risk indicators in a sample from six Arab countries. METHODS: A multinational cross-sectional study was conducted on a sample of 2924 participants, attending dental practices, aged 18-35 years from six Arab countries. Trained examiners assessed dentine hypersensitivity using the Schiff scale and scored the tooth with the highest value in each sextant. Participants were asked to complete a questionnaire that assessed the frequency of drinking and eating acidic foods and their oral health habits. RESULTS: Overall, the Schiff score 1 was found in 938 (32.6%), score 2 in 613 (21%) and score 3 in 274 (9%) of the participants. There was variation between countries with Saudi Arabia (13.9%) and Oman (15%) having the highest prevalence of hypersensitivity and Kuwait (2.2) and Jordan the lowest (4.8%). Participants who experienced toothache and difficulty eating once a day were significantly more likely to have Schiff score 2 or 3 (OR: 2.51, 95% CI: 1.54-2.87; OR: 1.34, 95% CI: 1.04-1.73, respectively). Furthermore, drinking soft drinks once a day was also significantly associated with dentine exposure (OR: 1.4, 95% CI: 1.19, 1.65). CONCLUSION: In this cross-sectional study, dentine sensitivity and exposure were common in Arab patient populations.

RESUMO

PURPOSE: Dentin hypersensitivity (DH) is a prevalent painful condition of the teeth, the management of which lies in the obliteration of patent dentinal tubules. The purpose of this study was to compare the efficacy of 5% potassium nitrate (PN), low-level laser therapy (LLLT), and combination of low-level laser therapy and 5% potassium nitrate (LLLT+PN) in patients with fluorotic and non-fluorotic hypersensitive teeth. MATERIALS AND METHODS: Ninety self reporting patients with DH completed the randomised, double-blind study. Patients were equally divided into fluorosis group (FG), with moderate to moderately severe fluorosis and the non-fluorosis group (NFG) and subdivided into 3 groups to receive PN, LLLT (810 nm, 1 W) alone and LLLT+PN. Each participant had at least one tooth eliciting a response of ≥ 3 on a visual analog scale (VAS) to evaporative, thermal and electric tactile stimulus (digital scratch-o-meter). The teeth were evaluated at baseline, 30 min post treatment, 1 week, 4 weeks and 12 weeks. The magnitude of pressure applied by the scratch-o-meter was also assessed for all three interventions. RESULTS: Statistically, LLLT+PN was more effective in alleviating DH at all time intervals compared to baseline. However, statistically significant results (p ˂ 0.05) were seen with LLLT+PN at 12 weeks in FG. Magnitude of pressure applied showed statistically significant differences with LLLT+PN at 30 min post treatment. CONCLUSION: LLLT+PN alleviated DH at all time intervals, with a greater effect in the fluorotic group. However, LLLT+PN was more efficacious in reducing DH at 12 weeks post treatment in the fluorotic group.

RESUMO

Introduction: Prevalence of dentine hypersensitivity (DH) may be on the increase as a result of changing lifestyles. This study aimed to assess the prevalence of DH and relative importance of associated factors in 18-35 year old Nigerians and compare to findings from a similar European study. Methods: Following ethical approval, 1349 subjects from the six geopolitical zones in Nigeria participated in this cross sectional study. DH was clinically evaluated by cold air tooth stimulation, patient pain rating (yes/no) and investigator rated pain using the Schiff ordinal scale (0-3). Erosive tooth wear using the BEWE index was assessed. A questionnaire regarding the nature of the DH, erosive dietary intakes, tooth brushing habits and other factors was completed by patients. Bivariate analysis was conducted. Results: 32.8% of patients reported pain on tooth stimulation and 32.9% scored ≥1 on Schiff scale for at least one tooth. Questionnaire reported sensitivity was 41.2%. There were statistically significant associations between Schiff score and clinically elicited DH (p < 0.001); and BEWE erosive tooth wear score and clinically elicited DH (p < 0.001). There were significant associations between DH and some oral hygiene practices such as brushing frequency, brush movement and brushing after breakfast. Fresh fruit and fruit/vegetable juice intake also showed significant association. Conclusion: The most important risk factors of DH for this population in Nigeria appear to be the frequency and characteristics of tooth brushing. This should be considered in its prevention and management.

RESUMO

The purpose of the study was clinical and laboratory analysis of the remineralizing properties and clinical efficacy of the course application of the Sensodyne Rapid Relief therapeutic and prophylactic toothpaste for sensitive teeth with tin fluoride. The study involved 50 overwise healthy patients aged from 18 to 25 years diagnosed with a localized form of hyperesthesia of hard dental tissues and no signs of acute inflammation of periodontal tissues. After 7 days of clinical observation and daily use of the toothpaste the hygienic condition of the oral cavity in all patients improved: oral hygiene index was 1.02±0.2 units; gum inflammation index (PMA) - 8.0±1.5%; the absence of hyperesthesia was diagnosed (1 point, p≤0.05). Examination of patients after 14 and 28 days confirmed the absence of pain in 100%, the organoleptic properties of the toothpaste under investigation were also highly appreciated by the participants. A laboratory study showed that patients have an increase in the pH value of mixed saliva and a decrease in its buffer capacity by 13.4±2.25%, which contributes to a more effective remineralizing effect of calcium ions by calcium-binding proteins of mixed saliva. The concentration of fluoride ions in the saliva of patients of both groups increased by average rate of 34±0.5% per week. The combination of tin and fluoride is more effective than fluoride alone. The presence of tin ions causes a higher ability of fluorides to bind with calcium ions on the surface of the dentin and dentinal tubules, inhibits the process of demineralization, enhances the additive interaction of the ions forming the acid-resistant layer on the surface of the dentin and dentinal tubules, leading to a decrease in hyperesthesia of the teeth.

RESUMO

Dentin hypersensitivity, a commonly presenting condition, is described as sharp pain resulting from the exposure of open dentin tubules to the oral environment in response to a varied assortment of stimuli. It is sometimes a difficult condition to diagnose, because the diagnosis is one of exclusion and all other potential causes must be examined first. The heterogeneity of this presentation, ranging from a minor inconvenience to the patient to a near incapacitating quality-of-life disorder, along with the wide array of treatment strategies pose challenges to the clinician. All dental professionals should be familiar with dentin hypersensitivity, such that they are able to effectively relieve patients of their pain. This article discusses the etiology, diagnosis, and effective management of dentin hypersensitivity.

RESUMO

This clinical trial evaluated the effect of preemptive use of the non-steroidal anti-inflammatory drug piroxicam in a single dose 30 min prior to in-office bleaching on the prevention of tooth sensitivity (TS) reported by patients. Fifty patients were submitted to two sessions of in-office tooth bleaching with 35% hydrogen peroxide used for 2 sessions, each consisting of a single 45-min application, with an interval of 7 days between session. Thirty minutes prior to the procedure, the patient randomly received a single dose of piroxicam (200 mg) or placebo in a double-blind, randomized, crossover design. The TS was evaluated using verbal rate (VRS) and visual analog (VAS) scales during the bleaching procedure and at 24 h after each session. The color changes were assessed by the Vita Bleachedguide scale 1 week after each bleaching session. Risk of TS was calculated from the VRS and analyzed by the McNemar test, while the level of TS was analyzed by the Mann-Whitney test. For the VAS, t-tests were used to compare data from the treatments at each assessment time. Data regarding color changes were subjected to Wilcoxon and Mann-Whitney tests (α=0.05). The preemptive administration of piroxicam did not affect the risk and level of TS compared to placebo, irrespective of the assessment time. The treatment sequence did not affect bleaching effectiveness. In conclusion, the administration of a single dose of piroxicam prior to in-office tooth bleaching was unable to significantly reduce the risk and level of TS.

RESUMO

PURPOSE: To compare the clinical efficacy of toothpastes containing Pro-Argin and NovaMin as dentin hypersensitivity (DH) treatment. MATERIALS AND METHODS: A systematic review and meta-analysis based on PRISMA was conducted (PROSPERO registration CRD42018095367). Electronic searches were performed in Pubmed, Scopus, Cochrane Library, Web of Science, Virtual Health Library and Open Grey until June 2018, with the terms [pro-argin OR arginine] AND [novamin OR calcium sodium phosphosilicate OR calcium sodium phospho silicate]. Randomised and non-randomised clinical trials comparing DH reduction in adults given Pro-argin-containing toothpastes and NovaMin-containing toothpastes were included. Study selection and quality assessment with Cochrane tool were performed. In the meta-analysis, the comparison between desensitising toothpastes was assessed by standardised mean difference (SMD) with 95% confidence intervals (CI). Certainty of evidence was evaluated with GRADE. RESULTS: Five studies fulfilled the inclusion criteria. In four included studies, a reduction in the DH under tactile stimulus between baseline and post-application times for both toothpastes was demonstrated. Three studies were suitable for meta-analysis. No statistically significant difference between the two toothpastes for DH reduction was observed at immediate (SMD = -1.05, CI = -3.52;1.41), 2-week (SMD = -0.55, CI = -2.59;1.48) and 4-week (SMD = -0.49, CI = -2.78;1.81) follow-up. Certainty of the evidence was very low. Included studies presented a high risk of bias. CONCLUSIONS: Pro-argin-containing and NovaMin-containing toothpastes showed effectiveness for DH reduction. No statistically significant difference between the two toothpastes was found. Thus, both can be prescribed to treat DH in adults with equivalent effectiveness up to four weeks.

RESUMO

BACKGROUND: Dentine hypersensitivity can impact functional status and everyday activities such as eating and talking. This study aimed to assess changes in oral health-related quality of life measures in individuals with dentine hypersensitivity following long-term use (24 weeks) of a commercially available toothpaste marketed for dentine hypersensitivity relief. METHODS: This study was conducted across two sites and enrolled 75 adults with ≥2 non-adjacent sensitive teeth. Participants were assigned to twice-daily brushing with toothpaste containing 0.454% w/w stannous fluoride (1100 ppm fluoride). Every 4 weeks, participant-reported outcomes were assessed using the Dentine Hypersensitivity Experience Questionnaire (DHEQ), a condition specific oral health-related quality of life scale that has five domains and includes questions on social and emotional impact, restrictions, adaptations and effect on life overall. Responses to a clinically applied evaporative (air) stimulus were assessed using the examiner-observed Schiff sensitivity scale and Labelled Magnitude Scales (LMS), which included dentine hypersensitivity-specific descriptors of intensity, duration, tolerability and descriptive qualities of the participant's response. RESULTS: Participant-reported outcomes demonstrated reduction of the impact of dentine hypersensitivity over time on health-related quality of life, as measured by the DHEQ. This reached statistical significance from Week 8 onwards (p < 0.0001 versus baseline) for the Total DHEQ score, with scores continually decreasing at each timepoint. Most domain scores followed a similar pattern. Statistically significant reductions were also detected for the examiner-observed Schiff Sensitivity Scale scores at all timepoints (including at 4 weeks) (p < 0.05), which were mirrored by LMS responses. The toothpaste was generally well-tolerated. CONCLUSIONS: These results show that long-term use of a sensitivity toothpaste containing 0.454% w/w stannous fluoride has a beneficial, ongoing, impact on the oral health-related quality of life of people with dentine hypersensitivity. TRIAL REGISTRATION: This study was registered at Clinicaltrials.gov ( https://clinicaltrials.gov/ct2/show/NCT02752958 ) on April 27, 2016.

RESUMO

Aims To determine patient awareness of periodontal health, dentine hypersensitivity and tooth wear, and their impact on oral health quality of life in patients attending NHS practices in South West England.Method In this cross-sectional, multi-centre epidemiological study 814 adult NHS patients completed an oral health questionnaire and then underwent a clinical examination. Pocket probing depths (mm), gingival recession (mm), gingival bleeding (yes/no), dentine hypersensitivity (Schiff score, and yes/no) and tooth wear (basic erosive wear examination score) were measured.Results Participants were regular dental attenders, with good oral hygiene practices and a low prevalence of periodontal disease (probing depth of 4 mm or more) (25%). For all conditions assessed, self-reported data and clinical indices were significantly positively associated, with the strongest associations being seen for dentine hypersensitivity and the weakest for tooth wear. Periodontal disease and dentine hypersensitivity were significantly associated with all four patient-reported measures of oral health quality of life studied.Conclusion This NHS patient population is well cared for and educated with respect to their oral health. The findings confirm the negative impact of periodontal disease and dentine hypersensitivity, and identifies the need to increase awareness of the signs and symptoms of tooth wear.

RESUMO

The objectives of this double-blind randomized clinical trial were to compare (a) the clinical times and (b) the occurrence and severity of postoperative sensitivity, of posterior restoration that used a universal adhesive, in a self-etch or selective enamel-etching technique, along with incremental or bulk-fill composites (presented in syringes or capsules). A total of 295 posterior restorations were placed according to the following groups: SETB - self-etch/bulk-fill in syringe; SETC - self-etch/bulk-fill in capsules; SETI - self-etch/incremental; SEEB - selective enamel-etching/bulk-fill in syringe; SEEC - selective enamel-etching/bulk-fill in capsules; and SEEI - selective enamel-etching/incremental. Clinical time was assessed by a reason (s/mm3) between the total volume of resin inserted and the total time required to perform the restorations. Postoperative sensitivity was evaluated using two scales (Numeric Rating Scale and Visual Analogue Scale). Mean clinical time results, analyzed by Wald's Chi-square, showed significant statistical differences among all groups (p<0.001), indicating that the restorative strategy affected the time required for the restoration. A generalized estimating equation model statistical analysis, performed to compare postoperative sensitivity, showed that neither the restorative technique, the adhesive strategy nor the presentation mode of the bulk-fill composite affected the overall risk of postoperative sensitivity (4.06 [2.22-6.81]). The use of bulk-fill composite, presented in capsules or syringes, is less time consuming and does not increase the risk or intensity of postoperative sensitivity relative to the traditional incremental technique.

RESUMO

BACKGROUND: The authors' aim was to evaluate the effectiveness of anti-inflammatory drugs on tooth sensitivity (TS) during and after in-office dental bleaching procedures. TYPES OF STUDIES REVIEWED: The authors selected randomized controlled trials in which the investigators compared anti-inflammatory drugs with a placebo to evaluate in-office dental bleaching TS. The authors performed an electronic search by using PubMed, ScienceDirect, and Embase. In addition, the authors searched other Web sites, such as ClinicalTrials.gov, to identify ongoing studies. RESULTS: The authors included 7 randomized controlled trials (324 adults) in the review. According to the extracted data, the authors performed the meta-analysis by using risk ratios and their 95% confidence intervals or by using the mean difference with a 95% confidence interval. The authors used the Cochrane Collaboration's tool to assess study quality. After the evaluation, the authors considered 6 studies to be high quality and a single study to be low quality. The overall results of the evaluation process revealed the absence of a clinically significant effect of anti-inflammatory drugs. CONCLUSIONS AND PRACTICAL IMPLICATIONS: The results of this analytic process indicated that anti-inflammatory drugs have no clinically significant effect on the TS that occurs due to in-office bleaching. Readers must analyze these results carefully given the limitations of this review, such as the small samples size and the heterogeneity among the studies in some stages of the evaluation process. The results of this analytical study highlight the need for more clinical studies to reach a significant conclusion because TS is one of the most important reasons for the cessation of bleaching treatment.

RESUMO

PURPOSE: This study investigated the role of desensitising-only and desensitising/whitening versions of arginine and calcium carbonate-containing (ACC) and calcium sodium phosphosilicate-containing (CSPS) toothpastes on surface loss and permeability of root dentine. MATERIALS AND METHODS: Slabs of human root dentine were embedded and exposed to citric acid solution to create a lesion resembling hypersensitive dentine. Sixty specimens were divided into six groups and exposed to slurries made with ACC (Colgate Sensitive Pro-Relief) and CSPS (Sensodyne Repair & Protect) toothpastes, in their desensitising or desensitising/whitening versions, an ordinary toothpaste (Crest Cavity Protection) or distilled water (DI). The other 60 specimens were brushed with either slurries or DI and assessed for surface loss. All specimens were analysed for dentine permeability. Data were subjected to analysis of variance (ANOVA) and Fisher's least statistically significant difference tests. RESULTS: ANOVA (p = 0.018) showed that in the group brushed with DI surface loss was lower than in the groups brushed with toothpastes, but there was no statistically significant difference among the ordinary, desensitising-only and desensitising/whitening toothpastes. Dentine permeability was not influenced by brushing (p = 0.125). Toothpastes affected dentine permeability (p = 0.004), with the groups submitted to desensitising-only and desensitising/whitening toothpastes presenting significantly lower permeability than those submitted to DI, but no difference existed between the group treated with the ordinary toothpaste and DI. CONCLUSION: In comparison to desensitising-only, desensitising/whitening toothpastes neither accounted for increased surface loss nor impaired tubule occlusion of root dentine.
