RESUMO
Casein is one of the most studied proteins with activity against dental caries. In particular, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) has shown promising remineralizing properties. In vivo evidence on the anticaries potential of CPP-ACP added to foodstuffs is elusive, nonetheless. Hence, this systematic review aimed at determining whether the use of CPP-ACP added to foodstuffs has a remineralizing or inhibitory action on dental demineralization either in vivo or in situ. The review protocol followed the PRISMA-P criteria and was registered in PROSPERO. PubMed, Scopus, and Web of Science databases were searched using predefined criteria, based on the PICO question: Is there an effect on dental caries upon adding CPP-ACP to milk, chewing gums, or candies? No year or language limits were applied. Article selection and data extraction were carried out independently by 2 investigators. Two hundred ten titles were examined, 23 were selected for full-text review, and 16 studies were included (2 in vivo and 14 in situ). CPP-ACP was added to candy in 2 studies, to milk in 2 studies, and to chewing gum in 12 studies. The main outcomes included enamel remineralization and activity against dental biofilm. The overall quality of the evidence was classified as moderate. The available evidence suggests that CPP-ACP added to milk, chewing gum, or candy has a potential remineralizing activity on tooth enamel, with some additional antibacterial activity on the dental biofilm. Further clinical studies are needed to verify if this effect is clinically significant in reducing the caries lesion incidence or to revert the demineralizing process.

Abstract Objective: To evaluate the effectiveness of chewing gums containing CPP-ACP in remineralisation of demineralised enamel around orthodontic brackets. Material and Methods: Enamel blocks from 120 bovine incisors were used. The blocks were flattened and polished, followed by the development of incipient subsurface caries. The blocks have been subjected to a baseline microhardness analysis. Orthodontic brackets were bonded to the exposed area of the blocks, reserving an area for hardness analysis. An in situ crossover (three-way crossover phases of 21 days with an interval of one week between them), controlled, randomised and blind experimental model was used, with the participation of 12 volunteers divided into groups: G1 - negative control group, without chewing gum; G2 - conventional sugar-free chewing gum, without CPP-ACP (placebo); and G3 - sugar-free chewing gum with CPP-ACP. The following parameters were analysed: superficial linear (Ra), volumetric roughness (Sa), and superficial structural loss, which was indicated by Gap measurement (difference between the healthy and treated area). Statistical tests used were the Friedman, Wilcoxon and Shapiro-Wilk, Kruskal Wallis' nonparametric tests and ANOVA. Results: There was a significant reduction in enamel microhardness after demineralisation in all the groups (p<0.05). This deleterious effect was attenuated in the three groups after the final evaluation, although there were no statistical differences (p<0.05); however, the final values did not return to the baseline values (p<0.05). Conclusion: Chewing gum containing CPP-ACP did not promote in situ remineralisation of demineralised enamel around orthodontic brackets.

Objetivo: mensurar o potencial erosivo de gomas de mascar não convencionais disponíveis no mercado brasileiro. Material e método: estudo experimental (in vitro) de caráter quantitativo. Foram adquiridos oito sabores de gomas de mascar: Poosh® (pinta língua); Plutonita® (abraço congelante, dentada ardente, baba de bruxa e língua ácida); e TNT® (sangue, lava e tumba). Para análise da acidez, foram realizadas leituras em triplicata do pH e acidez titulável (AT), utilizando um potenciômetro e eletrodo combinado de vidro em soluções obtidas após a maceração das gomas de mascar em água duplamente deionizada. Nas soluções com valores de pH inferiores a 5,5, foi mensurada a AT adicionando-se alíquotas de 100 µLNaOH 0,1 M, até alcançar pH 5,5. Os resultados foram submetidos aÌ Análise de Variância (ANOVA). As comparações das médias de pH e acidez titulável foram realizadas pelo teste de Tukey, com um nível de 5% de significância (p<0,05). Resultados: os valores de pH variaram entre 2,4 (abraço congelante) e 3,5 (baba de bruxa), diferin-do significantemente do controle (água mineral/pH=6,2). Os valores de acidez titulável variaram entre 628µL de NaOH 0,1 M (sangue) e 10700µL de NaOH 0,1 M (abraço congelante). A goma de mascar sabor abraço congelante apresentou o pH mais baixo e a mais elevada acidez titulável, diferindo significantemente dos demais sabores. Conclusões: as gomas de mascar avaliadas são ácidas, mas diferem quanto ao seu potencial erosivo. Seu consumo abusivo pode constituir um fator de risco para erosão dental.(AU)
Objective: to measure the erosive potential of non- -conventional chewing gums available in the Brazilian market. Material and methods: this is an in vitro study using the following flavors of chewing gums from the Brazilian market: Poosh® (tongue cleaner); Plutonita® (freezing hug, burning bite, witch slime and acid tongue); TNT® (blood, lava and tomb). For acidity analysis, pH and titratable acidity (TA) readings were performed in triplicate using a potentiometer and combined glass electrode in solutions obtained after maceration of the chewing gums in double deionized water. In solutions with pH values below 5.5, the TA was measured by adding aliquots of 100 µL 0.1 M NaOH, until pH 5.5 was reached. The results were submitted to Analysis of Variance (ANOVA). Comparisons of pH and titratable acidity means were performed by Tukey test at a 5% significance level (p<0.05). Results: the pH values that ranged from 2.4 (freezing hug) to 3.5 (witch's slime) differed significantly from the control (mineral water/ pH=6.2). Titratable acidity values ranged from 628µL of 0.1 M NaOH (blood) to 10700µL of 0.1 M NaOH (freezing hug). The freezing hug flavor chewing gum had the lowest pH and the highest titratable acidity differing significantly from the other flavors. Conclusions: the evaluated chewing gums are acidic, but differ in their erosive potential. Their abusive consumption may constitute a risk factor for dental erosion.(AU)

Background: The implementation of the self-cleaning practice is of fundamental importance for the maintenance of oral health and to remove the human dental biofilm which is considered the main etiological factor for the development of caries and periodontal diseases. Objective: This study aimed to evaluate the use of chewing gum, Rolly Brush® and apples as forms of mechanical control and removal of the dental biofilm in the absence of brushing. Materials and Methods: Eighteen volunteers were submitted to plaque index evaluation after a period of 24 hours of no oral hygiene. Then, they would use one of the methods: chewing gum, Rolly Brush®, apple or tooth brushing, chosen by a draw, for one minute, and then, plaque index was evaluated again. This stage was repeated until all participants were submitted to all selected methods, in periods of 24 hours each. Results: Dental brushing was more effective when compared to each of the other methods applied and there was a statistically significant reduction of dental plaque index after apllying all methods of cleaning in all groups. Conclusion: Chewing gum, Rolly Brush® and apple may be used as auxiliary to dental brushing or when such method is impossible to be performed. Clinicaltrials.gov: number of protocol NCT 03.601.585.

RESUMO
ABSTRACT Objective: To evaluate the improvement in masticatory performances two weeks after posterior implant restoration. Material and Methods: Nine patients with missing first and second molars were included in the study. Masticatory performances were evaluated using subjective and objective methods utilizing color-changeable chewing gum and the visual analog scale (VAS) assessment. The subjects were asked to chew the color-changeable chewing gums before and two weeks after the posterior implant restoration. Their expectations regarding aesthetics and function were verified on the VAS before implant placement. Additionally, the VAS was used for the posttreatment completion rating two weeks after the implant restoration. Results: Significant differences in masticatory performance were noted at baseline (before implant posterior restoration) and two weeks after implant restoration (p<0.05). The posttreatment aesthetic and functional expectations ratings significantly exceeded the expectations (p<0.05). Conclusion: Masticatory performances were improved two weeks after implant restoration. In addition, the significant posttreatment ratings of the patients exceeded their initial expectations. In particular, patients with poor masticatory functions demonstrated significant improvements and satisfaction following implant restoration compared to those with good mastication. These findings indicate that a posterior implant restoration can increase the masticatory performance.

Abstract Introduction: the aim of this study was to assess the adherence to a preventive treatment of plaque-induced oral diseases using two sugar-free gums, establishing their effect on cariogenic bacteria counts as a biological marker of treatment response. Methods: a double-blind, randomized, parallel-group, controlled intervention study was conducted in 96 young adult university students in an experimental period of 30 days. Participants were distributed into two groups and given a chewing gum with either pentitol or hexitol + CPP-ACP complex to be taken three times a day for 20 minutes after conventional oral hygiene. Saliva samples were collected at baseline to evaluate counts of Streptococcus mutans (SM) and Lactobacillus spp. A survey was conducted at the end of the experimental period to assess the levels of adherence to treatment, remeasuring bacterial counts. Results: SM counts showed statistically significant differences between the study groups at the end of the experimental period, with a decreasing tendency in both groups. Intragroup difference was observed in patients who took pentitol gum with a marked reduction in SM counts. Conclusion: the final estimate of adherence to treatment showed that the type of chewing gum patients were given had no influence and therefore such gums can be used, considering the therapeutic agents that most contribute to patient's particular case and preferences.
Resumen Introducción: el objetivo consistió en evaluar la adherencia a un tratamiento preventivo de enfermedades bucales inducidas por placa bacteriana, utilizando dos gomas de mascar sin azúcar y establecer su efecto sobre recuentos de bacterias cariogénicas como indicador biológico de los efectos del tratamiento. Métodos: se realizó un estudio de intervención, doble ciego, de grupos paralelos, aleatorizado controlado, en 96 adultos jóvenes universitarios, en un período experimental de 30 días. Los participantes fueron distribuidos en dos grupos con asignación de una goma de mascar con pentitol o con hexitol + complejo CPP-ACP que debían ser consumidas 20 minutos/tres veces al día después de la higiene oral convencional. Al inicio del studio fueron recolectadas muestras de saliva para evaluar recuentos de Estreptococos del grupo mutans (SM) y Lactobacillus spp. Al finalizar el período experimental, se realizó una encuesta para evaluar los niveles deadherencia al tratamiento y los recuentos bacterianos fueron medidos nuevamente. Resultados: Los recuentos de SM mostraron diferencias estadísticamente significativas entre los grupos de estudio al final del período experimental, con tendencia hacia la disminución en ambos grupos. Se observó diferencia intragrupo en los pacientes que consumieron la goma de mascar con pentitol, con marcada reducción de los recuentos de SM. Conclusión: la estimación final de la adherencia al tratamiento mostró que el tipo de goma de mascar asignada al paciente no tuvo influencia y, por lo tanto, estas pueden ser utilizadas teniendo en cuenta los agentes terapéuticos que más aporten al caso particular del paciente y las preferencias del mismo.

AIM: The aim of this study was to assess whether differences in inter-individual clinical and prosthodontic variables affect masticatory performance (MP) of edentulous subjects who received new complete dentures. MATERIALS AND METHODS: There were 204 edentulous participants who received new maxillary and mandibular complete dentures between October 2014 and March 2018 at a university clinic. MP was measured by a mixing ability test with a two-coloured chewing gum for 20 and 50 chewing cycles. The outcome variable was the degree of colour mixing of the chewed gum, expressed by the variation of hue (VOH) and measured by electronic colourimetric analysis. Explanatory variables included gender and age, quality of the dentures, classification of edentulous ridges and prognostic features, time since the insertion of the new dentures and patient-reported outcomes related to complete denture treatment. Bivariate correlation tests, multiple linear regression and a linear mixed model were used for data analysis. RESULTS: Mean VOH values were 0.57 (±0.13) and 0.43 (±0.16) for 20 and 50 chewing cycles, respectively. Mixing ability was higher in females than in males for 20 (P = 0.036) and 50 (P = 0.006) chewing cycles. No effects on the patient-reported outcome measures were observed. The time since denture delivery, gender, age and Prosthodontic Diagnostic Index (PDI) score were independently associated with masticatory performance at 20 and/or 50 chewing cycles. Overall masticatory performance tested by the linear mixed-effect model confirmed that VOH value was negatively influenced by male gender, older age and shorter time since denture delivery. CONCLUSION: Masticatory performance seems to be improved with the continuous use of newly inserted dentures and negatively influenced by advanced age.

ABSTRACT Objective: To identify and analyze the evidence on the effect of chewing gum on thirst in adults. Method: Integrative review, guided by the question: "What is the scientific evidence about the effects of chewing gum on adult's thirst?" LILACS, PubMed, Scopus and Web of Science were the databases consulted. Results: Of a total of 2,414 articles found, 12 papers were selected whose publications varied between 1991 and 2016. The use of chewing gum resulted in increased salivary volume (five studies), xerostomia relief (seven studies), and thirst reduction (four studies). It was not possible to establish the number of chewing gums per day, being frequent the recommendation to use as desired. There was a predominance of studies with patients under dialysis and with cancer. Conclusion: Chewing gum is an effective strategy to reduce thirst discomfort in adults.

OBJECTIVES: The aim of this study was to test the effect of a single-implant mandibular overdenture (SIMO), compared with conventional complete denture (CD), on masticatory performance measured by the mixing ability of a two-coloured chewing gum. METHODS: A sample of edentulous subjects was randomly assigned to the SIMO (n = 15) and CD (n = 19) groups. Patients in both groups received a set of new complete dentures, and the SIMO group received a single implant in the symphyseal region of the mandible (Straumann® Standard Plus SLActive®) and an eliptical matrix and ball attachment for denture retention. Masticatory tests were performed using a two-colour chewing gum (Vivident Fruitswing, Perfetti van Melle, Turkey) for 20 and 50 chewing cycles. Colour-mixing ability was assessed by electronic colourimetric analysis (ViewGum©, Dhal Software, Greece), expressed by the variance of hue. Tests were performed at baseline and at the 6- and 12-month follow-ups. Multilevel linear regression was used to model the changes in masticatory performance. RESULTS: Groups were similar at baseline for 20 and 50 cycles (P > 0.05). A significant linear effect was observed on time points for 20 and 50 cycles (P < 0.001). No difference was observed between treatment groups factor (P > 0.05). However, the way masticatory performance varied according to time points differed in the CD and SIMO groups for 20 cycles (P = 0.048). CONCLUSION: Masticatory performance improved significantly after 12 months, irrespective to the insertion of a single implant to retain a mandibular overdenture. Moreover, results suggest that SIMO treatment may perform better than CD in the shorter follow-up period.

BACKGROUND: A number of studies with conflicting results have evaluated the effect of chewing gum on post-operative gastrointestinal recovery in patients after major colorectal surgery. OBJECTIVE: The objective of the study was to study the efficacy of chewing gum in patients with rectal cancer after elective open proctectomy only. METHODS: A randomized controlled clinical trial was performed. We recruited patients who would undergo elective open proctectomy for rectal cancer in Sichuan Academy of Medical Sciences and Sichuan Provincial People's Hospital. Patients in the intervention arm received chewing gum 3 times a day postoperatively. All patients in the trial were placed on the same perioperative management and standardized post-operative care plans. The primary outcome was time to the first peristalsis sounds, time to first flatus and the first defecation. RESULTS: A total of 89 patients were recruited. The time to the first flatus was 42.33 ± 3.46 h in the gum group and 49.20 ± 1.42 h in the control group (p < 0.05). The time to the first defecation was significantly shorter in the gum-chewing group than in the control group (66.07 ± 2.36 vs. 78.37 ± 1.62 h; p < 0.05). Post-operative ileus (POI) was confirmed in 2 patients in the gum-chewing group and in 7 in the control group (7.0% vs. 23.9%; p = 0.028). DISCUSSION: The present study suggests that chewing gum is a method to reduce the time to first flatus, time to first defecation and POI in patients undergoing elective open proctectomy for rectal cancer.

INTRODUCTION: Different studies have assessed the influence of chewing gum to aid control of appetite and reduce food intake. PURPOSE: The aims of the present study were to evaluate the effects of chewing gum on satiety, food hedonics and snack intake and to explore the potential effects of the combination of Garcinia c ambogia, green coffee extract and L-carnitine on satiety, when administered in a gum format. METHODS: This was a prospective study in which 57 subjects randomly received three kinds of treatments, in a crossover design: (1) active gum; (2) placebo gum; and (3) no gum. Food preferences and appetite sensations were evaluated by means of the Leeds Food Preference Questionnaire and visual analog scales. RESULTS: There was a significant reduction in low-fat sweet snack intake with placebo gum and the active gum compared to no gum and a reduction in high-fat sweet snack intake with the active gum compared to placebo gum and no gum. Total caloric intake was only reduced in the active gum condition. Both the active and placebo gum conditions significantly reduced hunger and prospective food consumption and increased fullness compared to no gum and were associated with a reduced wanting for sweet food in the LFPQ, consistent in a reduction in the relative preference for sweet snacks versus savoury snacks. CONCLUSION: This study supports the notion that chewing gum containing nutraceutical products might aid in the control over snack intake and reduce hunger sensations.

Resumen Todas las formas comercialmente disponibles de terapia de reemplazo de nicotina (TRN) (chicles, parche transdérmico, aerosol nasal, inhalador y tabletas sublinguales / lozenges) pueden ayudar a de dejar de fumar con éxito. TRN aumenta la tasa cesación en un 50 a 70%. La combinación de un parche de nicotina con una forma de administración rápida de TRN es más eficaz que un solo tipo de NRT. No hay diferencia en la eficacia entre TRN y bupropión, la combinación de NRT y bupropión es más efectiva que bupropión solamente. Los efectos de TRN son en gran parte independientes de la duración de la terapia, la intensidad del apoyo prestado o lugar en el que se ofreció. Según expertos chilenos, se puede usar TRN en adolescentes, en forma de chicles de 2 mg asociado a terapia conductual. Si una embarazada expresa un claro deseo de recibir TRN, se sugiere (i) discutir con ella los riesgos y beneficios asociados, (ii) utilizarla sólo si falla la cesación con medidas no farmacológicas y (iii) utilizar el criterio profesional al decidir si ofrecer la prescripción de TRN, tomando en cuenta el nivel de adicción de la embarazada y la presencia de comorbilidades. Estos fármacos existen en Chile, pero no están hasta el momento disponibles en el sistema público de salud.
All commercially available forms of nicotine replacement therapy (NRT) (gum, transdermal patch, nasal spray, inhaler and sublingual tablets/pills) can help to quit smoking successfully. NRT increases the cessation rate by 50 to 70%. The combination of a nicotine patch with a rapid dosage form of NRT is more effective than a single type of NRT. There is no difference in efficacy between NRT and bupropion, the combination of NRT and bupropion is more effective than bupropion alone. The effects are largely independent of the duration of therapy, the intensity of the support provided or the setting in which the NRT was offered. According to Chilean experts, NRT can be used in adolescents, as chewing gum 2 mg adding behavioral therapy. If a pregnant woman expresses a clear desire to use NRT, it is suggested (i) discuss the associated risks and benefits with her, (ii) use it only if the cessation fails with non-pharmacological measures and iii) use the professional approach when deciding whether to offer the prescription of NRT, considering the level of addiction of the pregnant woman and the presence of comorbidities. TRN exists in Chile, but is not currently available in the public health system.

Abstract Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is able to increase salivary calcium and phosphate levels at an acidic pH. Previous studies demonstrated that a CPP-ACP chewing gum was able to enhance the re-hardening of erosion lesions, but could not diminish enamel hardness loss. Therefore, there is no consensus regarding the effectiveness of CPP-ACP on dental erosion. Objective This in situ study investigated the ability of a CPP-ACP chewing gum in preventing erosive enamel loss. Material and Methods: During three experimental crossover phases (one phase per group) of seven days each, eight volunteers wore palatal devices with human enamel blocks. The groups were: GI - Sugar free chewing gum with CPP-ACP; GII - Conventional sugar free chewing gum; and GIII - No chewing gum (control). Erosive challenge was extraorally performed by immersion of the enamel blocks in cola drink (5 min, 4x/day). After each challenge, in groups CPP and No CPP, volunteers chewed one unit of the corresponding chewing gum for 30 minutes. Quantitative analysis of enamel loss was performed by profilometry (µm). Data were analyzed by Repeated-Measures ANOVA and Tukey's test (p<0.05). Results The use of chewing gum (CPP and No CPP) resulted in lower erosive enamel loss compared with the control group (p<0.05). CPP-ACP chewing gum (CPP) did not improve the protection against erosive enamel loss compared with conventional chewing gum (No CPP) (p>0.05). Conclusion The CPP-ACP chewing gum was not able to enhance the anti-erosive effect of conventional chewing gum against enamel loss.

Objective: To evaluate salivary flow and buffer capacity by means of mechanical and chemical-mechanical stimuli, through the use of chewing gums. Material and Methods: The study was a cross-sectional study with 12 volunteers, divided into three groups, in three phases: Group A: paraffin gum; Group B: Chewing gum without sucrose, flavored (Trident®); Group C: Flavored chewing gum, without sucrose and amorphous calcium casein-phosphate phosphopeptide (Trident Total®). The stimulated total saliva was collected after 5 minutes of mastication of one of the products and the volume was expressed in mL / min. The same sample was submitted to pH measurement with the use of a digital potentiometer, where the results were classified in normal buffer capacity (final pH between 5.0 and 7.0) or low (final pH <4.0). The results were evaluated regarding the normality of the sample distribution (Shapiro-Wilk test), Analysis of Variance (ANOVA) and Tukey's test. Results: Chewing gums increased the salivary flow of the volunteers, when compared to the control group (paraffin) (1.53 mL / min), differing statistically from the group, although there was no difference between Trident® (2.09 mL / Min) and Trident Total® (2.06mL / min). Regarding the buffer capacity, the values obtained were 6.94 (paraffin), 6.99 (Trident®) and 6.93 (Trident Total®), with no difference between groups (p = 0.713). Conclusion: It was concluded that chewing gums, with and without CPP-ACP, increased the salivary flow in relation to the control group. In relation to buffer capacity the values obtained for chewing gums with and without CPP-ACP, are shown to be within the normal range.

Dental caries is one of the most prevalent diseases. The WHO has classified it as one of the major public health problems worldwide. That is why a special emphasis has been paid to developing new preventive methods and the use of gum without sugar has been included as one of them. This strategy has significant benefits on oral health due to: (1) saliva stimulation, which favors teeth clearance and regulates the pH; (2) remineralization promotion as a result of the above and incorporation of minerals to the gum;(3) mechanical control of the bacterial plaque; (4) replacement of sugar by sweeteners which are harmful for bacteria (the most commonly used is xylitol) and (5) incorporation of active agents such as bicarbonate, casein, urea, chlorhexidine and chitosan, among others. Despite these benefits, the effect of the gum is considered to be weak for dental caries prevention when used instead of brushing. Therefore, its implementation must be proposed as a complement to oral hygiene routines and not as a preventive measure by itself. It is necessary to carry out a greater amount of clinical trials to evaluate its effectiveness in a context of high biological variability in the short and long term and including patients of different sex, age, socio-economic status and systemic health...
La caries dental constituye una de las enfermedades de mayor prevalencia, siendo catalogada por la OMS como uno de los principales problemas de saludpública a nivel mundial. Por ésta razón se ha enfatizado en el desarrollo de nuevos métodos preventivos a los que se ha incorporado el uso del chicle sin azúcar. Con esta estrategia es posible obtener importantes beneficios para la salud oral producto de: (1) estimulación de la salivación, lo que favorece el aclaramiento y regula el pH; (2) promoción de la remineralización como consecuencia de lo anterior y de la incorporación de minerales a la goma de mascar; (3) control mecánico de la placa bacteriana; (4) sustitucióndel azúcar por edulcorantes nocivos para las bacterias, de los cuales el más utilizado es el xilitol; e (5) incorporaciónde agentes activos tales como bicarbonato, caseína, urea, clorhexidina y quitosano, entre otros. Pese a proporcionar ésta serie de beneficios se considera que el efecto del chiclees débil en la prevención de caries cuando éste propósito se busca en ausencia de cepillado dental y por lo tanto debe proponerse su implementación como complemento a las rutinas de higiene oral y no como una medida preventiva por sí sola, siendo necesario realizar una mayor cantidad de ensayos clínicos, a corto y largo plazo, que evalúen laefectividad en un contexto de alta variabilidad biológica, incluyendo pacientes de distinto sexo, edad, situación socioeconómica y salud sistémica...

To determine the time required for pH buffering by saliva after use sugary(S), sugar-free (SF) and probiotic (P) chewing gums.Material and Methods:Saliva was collected from 12 volunteer dental students at UNESP São José dos Campos / SP, in order to determine salivary flow (SR) rate and initial buffering capacity (BC). Participants presenting BC>4.0 were invited to continue the research. Participants chewed different types of gum for 3 consecutive days, and saliva was collected at 0-1min, 1-5min, and 5-10min intervals. The time required to neutralize saliva pH after chewing the different types of gum was analyzed by RM ANOVA and Tukey's test (5%).Results:RM ANOVA revealed significant influence on the interaction effect (chewing gum and time) (statisticFdf(4.66)= 4.027, p = 0.0055 <0.05). According to TukeyÆs test, differences were observed in the following circumstances: for the 0-1 interval, BC of S differs from SF and P; BC of S differs from SF at 1-5 min and 5-10 min intervals; and, 0-1min interval differs from 1-5 min and 5-10 min intervals for both S and SF. Conclusion:Dentistry students showed no increased predispositionto dental caries with a specific type of chewing gum. Although time for pH recovery differed according to gum type, they were all above the critical range for enamel demineralization...

O efeito protetor da caseína fosfopeptídea fosfato de cálcio amorfo (CPP-ACP) contra a erosão dentária é controverso. Este estudo in situ teve como objetivo investigar a capacidade de uma goma de mascar com CPP-ACP em prevenir uma única desmineralização erosiva. Blocos de esmalte bovino (120) selecionados pela dureza superficial inicial foram divididos aleatoriamente entre os grupos: GI - goma de mascar com CPP-ACP, GII - goma de mascar sem CPP-ACP e GIII - controle negativo para avaliação do efeito protetor sem estimulação salivar (sem goma de mascar). Dezenove voluntários participaram do estudo durante três fases cruzadas de 2 h cada. Nas fases de GI e GII os voluntários usaram dispositivos intrabucais palatinos contendo 2 blocos de esmalte, durante 120 minutos e mascaram uma unidade da goma de mascar correspondente ao grupo nos últimos 30 minutos. No grupo controle os voluntários usaram o dispositivo intrabucal por 2h, sem uso de goma de mascar. Em cada fase, imediatamente após a utilização, os dispositivos intrabucais foram imersos em refrigerante tipo cola durante 5 minutos para promover a desmineralização erosiva. A dureza superficial final foi mensurada e os valores foram utilizados para o cálculo do percentual de perda de dureza. Os dados foram analisados por ANOVA de medidas repetidas e teste Tukey (α = 5%). Menor perda de dureza do esmalte foi encontrada após a utilização de goma de mascar com (GI - 32,7%) e sem (GII - 33,5%) CPP-ACP relação ao efeito salivar sem estimulação (GIII - 39,8%) (p <0,05). Não houve diferença entre GI e GII (p> 0,05). Os resultados sugerem que a utilização de goma de mascar imediatamente antes de uma desmineralização erosiva é capaz de diminuir a perda de dureza do esmalte.

The erosion-protective effect of CPP-ACP is controversial. This in situ study aimed to investigate the ability of CPP-ACP chewing gum to prevent a single event of erosive demineralization. Bovine enamel blocks (120), after selection (initial surface hardness) were randomly assigned to groups: GI-chewing gum with CPP-ACP, GIIchewing gum without CPP-ACP and Control group-salivary effect without stimulation (no gum). Nineteen volunteers participated on this study during 3 crossover phases of 2 h. On GI and GII, the volunteers wore intraoral palatal devices for 120 min and chewed a unit of the corresponding chewing gum on the last 30 min. On Control group the volunteer wore the appliance for 2 h, without chewing gum. On each phase immediately after the intraoral use, devices were extra orally immersed in cola drink for 5 minutes to promote erosive demineralization. The percentage of surface hardness loss was calculated. The data were analyzed by Repeated Measures ANOVA and Turkeys test. Less enamel hardness loss was found after the use of chewing gum with (GI-32.7 %) and without (GII-33.5%) CPP-ACP when compared to salivary effect without stimulation (control- 39.8%) (p<0.05). There was no difference between GI and GII (p>0.05). The results suggest that the use of chewing gum immediately before an erosive demineralization is able to diminish the enamel hardness loss.
