Effectiveness of desensitizing toothpastes in reducing tooth sensitivity after tooth bleaching: a systematic review.

OBJECTIVE: To evaluate the effectiveness of desensitizing toothpastes in reducing post-bleaching tooth sensitivity. MATERIALS AND METHODS: A systematic review of randomized clinical trials was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Electronic searches were conducted in the PubMed/MEDLINE, Scopus, Web of Science, The Cochrane Library and Embase databases, using the following terms: (dentifrices OR toothpaste) AND (sensitive OR sensitivity OR dental sensitivity) AND (dental bleaching OR tooth bleaching OR dental whitening OR tooth whitening). RESULTS: Five studies involving 387 individuals undergoing in-office or at-home teeth bleaching were reviewed. Desensitizing toothpastes reduced sensitivity effectively after home bleaching with 22% carbamide peroxide and single-session in-office bleaching with 35% hydrogen peroxide. However, they were ineffective for home bleaching with 16% carbamide peroxide and in-office bleaching across two sessions with 35% or 38% hydrogen peroxide. CONCLUSION: Desensitizing toothpastes are effective for home bleaching with high concentration carbamide peroxide and single-session in-office bleaching with highly concentrated hydrogen peroxide, but ineffective for home bleaching with low concentration carbamide peroxide and two-session in-office bleaching with concentrated hydrogen peroxide.

Factors associated with edentulous patients' willingness about implant-supported complete denture: a multivariate analysis.

OBJECTIVE: The aim of this study was to evaluate the factors influencing edentulous patients' willingness about mandibular implant-supported complete denture. MATERIALS AND METHODS: A cross-sectional study was carried out with 117 bimaxillary edentulous patients wearing removable complete dentures (CDs). Patients were assessed concerning denture-related items (number of previous mandibular CDs, previous denture wearing period, dentures maker professional, and regular wearing of previous mandibular dentures) and individual-related aspects, such as mandibular edentulousness period, mandibular bone height, and willingness to the use of mandibular implant-supported complete denture. Masticatory performance was evaluated by the median particle diameter. Mandibular bone height and satisfaction were assessed using a validated method. The Chi-square test was used for data analysis and prevalence ratios were adjusted by using multivariate Poisson regression, both with 95% confidence interval. RESULTS: A total of 78 participants (66.7%) were interested in mandibular implant-supported overdenture (mean age 65.33 ± 9.49). Masticatory performance was not influenced by choosing mandibular implant-supported complete denture. The preference about mandibular implant-supported complete denture was correlated with longer mandibular complete denture experience (p = 0.021) and it was significantly associated with dissatisfaction about retention (p = 0.005). CONCLUSION: Previous experience with mandibular complete dentures and dissatisfaction about retention influence the willingness about mandibular implant-supported overdenture. CLINICAL RELEVANCE: Many factors are associated with rehabilitation preferences for edentulous patients and mandibular implant-supported complete denture is one of the available alternatives. Therefore, this study has demonstrated the factors influencing the decision to replace a mandibular conventional complete denture by dental implant treatment based on patient's outcomes. Such finding may be considered as a relevant aspect towards shared decision-making for prosthodontic rehabilitation of edentulous patients.

Incidence and risk factors for non-adaptation of new mandibular complete dentures: a clinical trial.

OBJECTIVE: To investigate the incidence and risk factors for non-adaptation of the conventional mandibular complete denture (CMCD). MATERIALS AND METHODS: A total of 108 edentulous patients were rehabilitated with complete dentures (CDs) and followed up at 3- and 6-month intervals. Adaptation was confirmed based on chewing, phonetics, and comfortable swallowing with the CDs. The risk factors among sociodemographic and patient-centered factors were analyzed. Statistical analyses included the chi-square test and then a multivariate analysis. RESULTS: After 3 months, 38.0% of patients showed non-adaptation to CMCDs. Non-adaptation was significantly associated with the absence of previous mandibular denture experience (p = 0.042), ulcerations after 15 days of rehabilitation (p < 0.001), and a reduced posterior mandibular ridge (p = 0.035). After 6 months, this incidence decreased to 14.1%. The factors associated with non-adaptation were ulcerative lesions after 15 (p < 0.001) and 30 (p < 0.001) days of the delivery of CDs and the non-regular use of mandibular CDs (p < 0.001). CONCLUSION: The incidence of non-adaptation was higher after 3 months, with reduction after 6 months. Sociodemographic variables did not influence the adaptation. After 3 months, the absence of previous experience, traumatic ulcers, and reduced mandibular ridges hindered the adaptation of patients to mandibular CDs. After 6 months, only the occurrence of ulcerative lesions and non-regular wear of dentures were risk factors for non-adaptation. CLINICAL RELEVANCE: A considerable number of patients have difficulties in adapting to the mandibular dentures. Identifying the factors of non-adaptation of the dentures will contribute to increasing the predictability of this critical adaptation period.

Efficacy of prostheses bonding using silane incorporated to universal adhesives or applied separately: A systematic review.

Currently, the long-term success of esthetic rehabilitation with ceramics is required. Hence, professional knowledge about the most indicated dental material for each clinical situation as well as its usage protocol is essential. The aim of this systematic review of clinical and laboratorial studies was to compare the bond strength of prostheses using silane incorporated to universal adhesives or applied separately. The literature search in databases "Cochrane Library," "MEDLINE," "Web of Science," "Scopus," "LILACS," "Scielo," and "Google Scholar" was based on the keywords "Silane;" "Silanes;" "Silane coupling agent;" "Universal adhesive;" and "Universal adhesives." A total of five articles were included in this review. In general, the studies showed better results for ceramic etching with hydrofluoric acid and application of silane separately to the universal adhesive. As a conclusion, the treatment with pure silane or as an additional pretreatment with universal adhesives improved the bond strength of glass ceramics. Hence, higher shear bond strength can be achieved, resulting in treatment longevity.

Effect of Cantilever Extension on Bone Loss in Mandibular Complete-Arch Implant-Supported Fixed Prostheses with Three and Four Implants.

PURPOSE: To compare the peri-implant bone loss of mandibular complete-arch implant-supported fixed prostheses (FPSs) supported by three and four implants and to correlate with the size of the horizontal and vertical distal cantilever at prosthesis placement (T1) and after 1 year (T2). MATERIALS AND METHODS: A total of 72 external hexagon (EH) type implants were placed in 20 participants. Of these, 24 supported an FPS with three implants (G3I) and 48 with four implants (G4I). The mandibular implants were named 1, 2, 3, and 4 according to their location in the arch, in a clockwise direction. Digital periapical radiographs were taken at times T1 and T2 for analysis and measurement of peri-implant bone loss. The horizontal and vertical distal cantilevers were measured with a digital caliper and correlated with peri-implant bone loss. RESULTS: The survival rate of implants in G3I was 91.66%, and in G4I it was 97.91%. The mean bone loss in G3I was 0.88 ± 0.89 mm, and in G4I it was 0.58 ± 0.78 mm (P = .225). There was no correlation between distal horizontal cantilevers and bone loss in the studied groups, with G3I being -0.25 (P = .197) and G4I -0.22 (P = .129). Larger vertical cantilevers of implants 1 (P = .018), 3 (P =.015), and 4 (P = .045) correlated with greater bone loss in G4I. CONCLUSIONS: The number of implants in an FPS did not influence peri-implant bone loss after 1 year of follow-up. Larger vertical cantilevers influenced greater bone loss in complete-arch implant-supported fixed prostheses supported by four implants.

Nonadaptation to New Mandibular Complete Dentures: A Survival Analysis and Interpretation of the Time to Adaptation.

PURPOSE: To determine the average time for patients to adapt to mandibular complete dentures (CDs) and the factors associated with this critical period. MATERIALS AND METHODS: In total, 108 completely edentulous patients were rehabilitated using CDs. Adaptation was evaluated based on the following criteria: mastication, comfort, speech, and swallowing with dentures. The Kaplan-Meier method was used to estimate the average time to adaptation. The logrank test was used to assess the adaptation period and associated factors. RESULTS: Of the 108 rehabilitated patients, 89 had adapted to mandibular CDs at the 6-month follow-up. The mean time to adaptation estimated from the Kaplan-Meier curve was 78.54 days (95% confidence interval [CI] 71.04 to 86.04). The factors associated with the adaptation period were previous experience with a mandibular denture (P = .032), the professional who made the previous CDs (P = .034), frequency of appearance of traumatic lesions after 15 days of rehabilitation (P = .023), posterior mandibular ridge height (P = .005), and regular use of the new dentures (P = .002). CONCLUSIONS: Most patients adapted to mandibular dentures after 2.6 months. Lack of prior experience with mandibular dentures, use of old dentures made by a dental technician, occurrence of traumatic injuries 15 days after CD delivery, presence of a resorbed posterior mandibular ridge, and nonregular wear were associated with longer adaptation time to new mandibular CDs.

Social representation of young people in higher education about sexually transmitted infections.

OBJECTIVE: to analyze the social representations about sexually transmitted infections elaborated by undergraduate students. METHODS: a descriptive, qualitative study, in the light of the structural approach of Social Representation Theory, carried out with 160 young undergraduate students, in the second half of 2019, in the city of Rio de Janeiro. Data were collected using a sociodemographic characterization questionnaire, knowledge and practices for preventing sexually transmitted infections, analyzed using descriptive statistics and a form of free evocations with the inducing term STD, analyzed using prototypical and similarity analysis. RESULTS: the representation's possible central nucleus is composed of lexicons aids, disease and HIV; the peripheral system by syphilis, sex, condoms, gonorrhea, prevention, infection, carelessness, HPV, herpes, ignorance, treatment, fear, unprotected-sex and danger. FINAL CONSIDERATIONS: social thinking about sexually transmitted infections is characterized by their recognition as diseases, which require barrier prevention measures, associating with unsafe sexual practices that arouse fear.

Use of impression technique to identify areas of super compression before installation of new complete dentures: a randomized double-blind trial.

OBJECTIVE: To identify pressure areas using an impression technique and to evaluate whether adjustment of dentures prior to installation can decrease ulcer frequency, number of adjustments, and improve satisfaction with treatment. MATERIALS AND METHODS: Fifty complete denture users were selected and randomly divided into two groups. Pressure areas were identified in 25 subjects using the impression technique with fluid silicone, and the denture base in these areas was adjusted before installation. A total of 25 subjects received new complete dentures without adjustments before installation. The number of ulcers observed was registered at 1, 7, 15, and 30 days after installation. Patient satisfaction was collected before and 1 month after the installation. The number of necessary post-installation adjustments was considered. Comparisons between the groups with respect to the number of ulcers, adjustments, and patient satisfaction were performed using the Mann-Whitney test. RESULTS: Identification of pressure areas reduced the number of ulcers after installation of the new prostheses. These results were observed in the 1- (p = 0.004) and 7-day (p = 0.002) adjustments for the maxilla and in all the adjustments for the mandible. The technique improved patient satisfaction (p = 0.031) and reduced the number of post-installation adjustments (p ≤ 0.001). CONCLUSION: A reduction in the incidence of ulcers, number of adjustments and improvement in patient satisfaction could be observed with the use of the technique.

Factors associated with total edentulism in the elderly and their impact on the self-perception of oral health and food.

OBJECTIVE: to identify the prevalence of and factors associated with total edentulism in the elderly Brazilian population. In addition, we sought to verify whether edentulism influences the self-perception of oral health and difficulty in eating. MATERIALS AND METHODS: This cross-sectional, population-based study used the database of the National Health Survey conducted in Brazil. The chi-square test was initially used for data analysis. Subsequently, a multivariate analysis of the Poisson multiple regression type was performed to verify the adjusted prevalence ratios. RESULTS: A total of 43,554 elderly people participated in the study, of whom 32% had completely lost their teeth. This total edentulism, based on the multivariate analysis, was associated with female gender (p < 0.001), advances age (p < 0.001), illiterate (p < 0.001), smokers (p < 0.001), and those who did not have health insurance (p < 0.001) or dental insurance (p < 0.001). Total edentulism had an impact on better self-perception of oral health (p < 0.001) and greater difficulties in eating (p = 0.001). CONCLUSION: It was concluded that total edentulism in the elderly is associated with worse socioeconomic conditions and a worse lifestyle. This condition has a negative impact on diet and positively affects self-perception of oral health.

Sexual behavior according to undergraduate students: perspective of cross-cultural nursing and intersectional framing.

OBJECTIVE: to discuss undergraduate students' sexual behavior from the perspective of social markers and cross-cultural care proposed by Madeleine Leininger. METHODS: descriptive-exploratory qualitative research, with a theoretical-philosophical foundation in the Transcultural Theory. Convenience sample was composed of 57 young people from two universities in Rio de Janeiro. The focus groups' content were analyzed lexically using the IRAMUTEQ software. RESULTS: four classes emerged: Young people's sexual scripts: between the fear of an unplanned pregnancy and the risk of exposure to sexually transmitted infections; Affective relationships: trust in steady sexual partners, apparent sense of security and disuse of condoms; Sexual practices, gender and cultural determinants: distinction in men's and women's role; Sexual partnerships, negotiation of condom use and vulnerability to sexually transmitted infections. FINAL CONSIDERATIONS: challenges are perceived for the attention to undergraduate students' sexual health, who verbalized risky sexual behaviors due to sociocultural vulnerabilities.

Social representation of spiritual surgeries in Umbanda: culture, religion and contributions of nursing theory.

OBJECTIVE: to analyze the social representation of spiritual surgeries in Umbanda for Bantu-Amerindian ritual mediums and their contributions to the cross-cultural care proposed by Madeleine Leininger. METHODS: a descriptive-exploratory, qualitative study, supported by the procedural approach of Social Representation Theory and Transcultural Nursing Theory, carried out with 30 Umbanda mediums of the Bantu-Amerindian ritual through interviews, submitted to the Iramuteq software for lexical analysis. RESULTS: mostly women, white, with an average of 46 years old and approximately 14 years of practice in Umbanda participated. The social representation of spiritual surgeries in Umbanda is objectified and anchored through a biomedical vision of care, encompassing a set of beliefs, values and practices as religious treatments, through faith, whose main objective is healing. FINAL CONSIDERATIONS: spiritual surgeries are a form of transcultural care, according to Madeleine Leininger's propositions, as they integrate the culture of a group through health care in Umbanda.

Effect of cantilever extension on bone loss in mandibular complete-arch implant-supported fixed prosthesis about 3 and 4 implants.

STATEMENT OF PROBLEM: The assessment of bone loss around implants has been widely studied, but the effect of cantilever length as a risk factor is not fully understood. PURPOSE: The objective of this randomized controlled clinical trial was to compare the peri-implant bone loss of mandibular complete-arch implant-supported fixed prosthesis supported (FPS) by 3 and 4 implants and to correlate with the size of the horizontal and vertical distal cantilever at prosthesis installation (T1) and after one year (T2). MATERIALS AND METHODS: 72 external hexagon (EH) type implants were installed in 20 participants. Of these, 24 support FPS with 3 implants (GI3) and 48 with 4 implants (GI4). The inferior implants were named 1, 2, 3, and 4 according to their location in the mandibular arch, in a clockwise direction. Digital periapical radiographs were taken at times T1 and T2 for analysis and measurement of peri-implant bone loss. The horizontal and vertical distal cantilevers were measured with a digital caliper and correlated with peri-implant bone loss. RESULTS: The survival rate of implants in GI3 was 91.66%, in GI4 it was 97.91%. The mean bone loss in GI3 was 0.88 (± 0.89) mm and in GI4 it was 0.58 (± 0.78) mm (P = 0.225). There was no correlation between distal horizontal cantilevers and bone loss in the studied groups, with GI3 being -0.25 (P=0.197) and GI4-0.22 (0.129). Larger vertical cantilevers of implants 1 (P=0.018), 3 (P=0.015) and 4 (P=0.045) correlated with greater bone loss in GI4. CONCLUSION: The number of implants in FPS did not influence peri-implant bone loss after 1 year of follow-up. Larger vertical cantilevers influenced greater bone loss in complete-arch implant-supported fixed prosthesis supported by 4 implants. Int J Prosthodont. 10.11607/ijp.8347.

Health personnel, family relationships and codependency of psychoactive substances: a phenomenological approach.

OBJECTIVES: to reflect on the daily life of family members dependent on psychoactive substances and the role of health professionals in Primary Care. METHODS: a descriptive investigation outlined in Maffesoli's phenomenological approach, carried out at a Basic Health Unit in Minas Gerais with eight family members dependent on psychoactive substances. Sociodemographic characterization data and in-depth interviews were collected and analyzed with support of NVivo Pro11® software. All ethical and legal aspects were met. RESULTS: physicians were the professionals most mentioned in participants' statements, who took on a dubious role with other health professionals: welcoming (positive perceptions about care received) and neglect (negative perceptions). FINAL CONSIDERATIONS: dependence on psychoactive substances imposes a burden on persons, their family members and health professionals. The role of establishing good relationships in the triad professionals-users-family members of primary care is inseparable in favor of treatment and preservation of their mental health.

Prosthodontic practice during the COVID-19 pandemic: prevention and implications.

The objective of this review is to identify preventive measures for COVID-19 to safeguard dental professionals providing prosthodontic dental care. Electronic searches were performed in PubMed, Scopus, and Cochrane databases using the following descriptors and/or words: "COVID-19," "SARS-CoV-2," "Dental practice," "Prosthodontics," and "Dental infection control." Prosthodontists are at high risk for exposure to the novel coronavirus through aerosols and possibly contaminated surfaces and indirect contact with dental laboratories and dental technicians through impressions, dental stone casts, and fixed and removable prosthetic appliances. Therefore, preventive measures should be implemented, including performing emergency treatments only, rescheduling patients with suspected disease, disinfecting surfaces and prosthodontic materials with biocidal substances, and using protective equipment such as N95 masks, disposable gowns, and face-shields.

Prevalence and factors associated with multimorbidities in Brazilian older adults. / Prevalência e fatores associados a multimorbidades em idosos brasileiros.

This study aimed to identify the prevalence of multimorbidity in Brazilian older adults and factors associated with socioeconomic and lifestyle variables. This is a cross-sectional, population-based study carried out with data from the National Health Survey database. Seniors with multimorbidity where the ones with a diagnosis of two or more chronic diseases. The chi-square test was used in data analysis, and then prevalence ratios were estimated through Poisson multiple regression, both with 95% confidence level. In total, 11,697 older adults were evaluated and the multimorbidity prevalence was 53.1%. As a result of the multivariate analysis, female seniors (p < 0.001), the oldest elderly (p = 0.002), those who were not single, more strongly associated with widowers (p = 0.001) and those with a health plan at the interview (p < 0.001) were associated with multimorbidity. Also, in comparison with older adults with two chronic diseases, women are associated with three (p = 0.003) and four or more chronic diseases (p < 0.001). We can conclude that multimorbidity in Brazilian older adults is a widespread condition and that it has been influenced by socioeconomic factors and is poorly related to lifestyle.

Objetivou-se identificar a prevalência de multimorbidade em idosos no Brasil e seus fatores associados com variáveis socioeconômicas e referentes ao estilo de vida. Trata-se de um estudo transversal e de base populacional. Para a sua realização, foi utilizada a base de dados da Pesquisa Nacional de Saúde. O idoso foi considerado com multimorbidade quando se tinha um diagnóstico de duas ou mais doenças crônicas. Na análise dos dados, o teste Qui-quadrado foi utilizado e em seguida as razões de prevalência foram estimadas por meio da regressão múltipla de Poisson, ambos com nível de confiança de 95%. Foram avaliados 11.697 idosos e a prevalência de multimorbidade foi de 53,1%. Como resultado na análise multivariada, os idosos do sexo feminino (p < 0,001), os mais envelhecidos (p = 0,002), os que não são solteiros, mais fortemente associados aos viúvos (p = 0,001) e os que possuem plano de saúde no ato da entrevista (p < 0,001) estão associados à multimorbidade. Ademais, comparando com os idosos que possuem duas doenças crônicas, as mulheres estão associadas à presença de três (p = 0,003) e quatro ou mais doenças crônicas (p < 0,001). Conclui-se que a multimorbidade em idosos brasileiros é uma condição bastante comum e que ela tem sido influenciada por fatores socioeconômicos e pouco relacionada ao estilo de vida.

Factors associated with the most frequent multimorbidities in Brazilian older adults. / Fatores associados às multimorbidades mais frequentes em idosos brasileiros.

This study aimed to identify an association between the most frequent multimorbidities in Brazilian older adults and socioeconomic and lifestyle variables. National Health Survey's data were used. The Chi-square test and the Poisson multiple regression were used to analyze data. A total of 5,575 older adults with multimorbidity and mean age of 70.3 years participated in the study. Most of them are female (66.3%), white (56.1%), are sedentary (75.3%), with low schooling (40%), no health plan (65.3%), did not consume alcohol (78.7%) and did not smoke (90.1%). The most prevalent multimorbidities were hypertension and high cholesterol (31.3%), hypertension and stroke (30.9%) and hypertension and diabetes (23.3%). There was an association of the first condition with females, younger adults and no tobacco use. On the other hand, the second condition was associated with females and low level of schooling. The third group was associated with low schooling, sedentary lifestyle and no tobacco use. We can conclude that multimorbidity in Brazilian older adults is a frequent condition in women, younger seniors and those socioeconomically disadvantaged. Also, socioeconomic conditions and lifestyle influenced the prevalence of primary multimorbidities.

Objetivou-se buscar associação entre as multimorbidades mais frequentes em idosos no Brasil e variáveis socioeconômicas e de estilo de vida. Para tal, foram utilizados os dados da Pesquisa Nacional de Saúde. O teste Qui-quadrado e a regressão múltipla de Poisson foram utilizados para a análise dos dados. Participaram 5.575 idosos com multimorbidade e idade média de 70,3 anos. A maioria é do sexo feminino (66,3%), brancos (56,1%), não realizam exercícios físicos (75,3%), de baixa escolaridade (40%), sem planos de saúde (65,3%), não consomem bebida alcoólica (78,7%) e não fumam (90,1%). As multimorbidades mais prevalentes foram: Hipertensão e Colesterol alto (31,3%), Hipertensão e AVC (30,9%) e Hipertensão e Diabetes (23,3%). Houve associação da primeira condição com o sexo feminino, idosos mais jovens e ao fato de não fumar. Já a segunda condição, esteve associada ao sexo feminino e à baixa escolaridade. A terceira associou-se à baixa escolaridade, aos que não realizam exercício físico e não fumam. Conclui-se que a multimorbidade em idosos brasileiros é uma condição frequente em mulheres, naqueles mais jovens e socioeconomicamente desfavorecidos. Ademais, para as principais multimorbidades as condições socioeconômicas e o estilo de vida influenciaram nas suas prevalências.

Manual Therapy in the Treatment of Myofascial Pain Related to Temporomandibular Disorders: A Systematic Review.

AIMS: To evaluate the effectiveness of manual therapy in the treatment of myofascial pain related to temporomandibular disorders. METHODS: Randomized clinical trials were searched in the Cochrane Library, MEDLINE, Web of Science, Scopus, LILACS, and SciELO databases using the following keywords: temporomandibular joint disorders; craniomandibular disorders; myofascial pain syndromes; myofascial pain; exercise therapy; myofunctional therapy; physical therapy modalities; clinical trial; prospective studies; and longitudinal studies. Studies using the RDC/TMD and manual therapy for myofascial pain were included. All studies were evaluated using the Cochrane Risk of Bias tool. RESULTS: Five studies were included in the present review. Of 279 total patients, 156 were treated with manual therapy only or manual therapy with counseling. Manual therapy was efficient for pain relief in all studies evaluated; however, manual therapy was not better than counseling or botulinum toxin. CONCLUSION: Manual therapy was better than no treatment in one study and better than counseling in another study; however, manual therapy combined with counseling was not statistically better than counseling alone, and manual therapy alone was not better than botulinum toxin. Manual therapy combined with home therapy was better than home therapy alone in one study. Further studies are required due to the inconclusive data and poor homogeneity found in this review.

Improvement in Quality of Life of Elderly Edentulous Patients with New Complete Dentures: A Systematic Review.

PURPOSE: To evaluate whether treatment with new complete dentures improves quality of life in elderly patients. MATERIALS AND METHODS: A literature search was conducted in the MEDLINE/PubMed, Scopus, LILACS, SciELO, Web of Science, and Cochrane Library databases using specific keywords for relevant articles published up to March 2018. Three reviewers obtained the data and compared the results from reports that evaluated denture wearers 60 years of age or older whose old dentures were replaced with new ones. RESULTS AND CONCLUSION: Of 282 published studies, 7 met the inclusion criteria (5 evaluated quality of life before and after treatment using the Oral Health Impact Profile, 1 using the Oral Impacts by Daily Performance, and 1 using the Geriatric Oral Health Assessment Index). The articles showed a similar increase in quality of life after elderly patients were treated with new complete dentures; however, the limited methodologic quality in the reported and analyzed studies underscores the need for more robust controlled investigations to strengthen the current body of evidence, which is limited.
