Abstract
Aim To evaluate the change in microflora in children suffering from severe early childhood caries (ECC) after full mouth rehabilitation. Materials and methods A total of 60 children, aged 3-5 years suffering from severe ECC who fulfilled the inclusion and exclusion criteria were included in the study. Pooled plaque samples were taken and subjected to quantitative reverse transcriptase polymerase chain reaction (PCR) to obtain baseline mean values of Streptococcus mutans (S. mutans), Streptococcus sobrinus (S. sobrinus), Candida albicans (C. albicans), and Candida dubliniensis (C. dubliniensis) before full mouth rehabilitation was done under general anesthesia. Posttreatment samples were collected at 6, 12, and 18 months. Wilcoxon signed-rank test was used to compare the mean values of S. mutans, S. sobrinus, C. albicans, and C. dubliniensis before and after full mouth rehabilitation. Results A total of 60 patients recruited for the study were present at the follow-up at 6 and 12 months. At 18 months, 55 patients returned, and five were lost due to follow-up. A statistically significant reduction was seen in all microorganisms at 6, 12, and 18 months compared to baseline values. At 18 months a slight increase in S. mutans, S. sobrinus, and C. albicans was seen. C. dubliniensis was not detected in any cases after full mouth rehabilitation. Caries recurrence was seen in four patients at 18 months. Conclusion Significant reduction of S. mutans, S. sobrinus, C. albicans, and C. dubliniensis was seen at 6, 12, and 18 months. A complete reduction of only C. dubliniensis was seen. A significant but not permanent reduction of S. mutans, S. sobrinus, and C. albicans. Caries recurrence was seen in 7.27% of patients at 18 months. How to cite this article Mathew MG, Jeevanandan G, Rathod NN.

Abstract
Introduction Early childhood caries (ECC) is the most chronic disease affecting children all over the world. Children often complain of pain and need complete rehabilitation, which is often done under general anesthesia due to extensive treatment and behavioral problems that are often encountered. The present study was undertaken to evaluate the total salivary antioxidant capacity of children with severe ECC (S-ECC) before and after complete dental rehabilitation and compare it with caries-free children. Materials and methods Salivary samples were obtained from 30 children aged 3-5 years and diagnosed with S-ECC, along with 30 age and sex-matched controls. Complete dental rehabilitation under general anesthesia was performed on the children with S-ECC, and follow-up salivary samples were obtained after 3 and 6 months postoperatively. Total salivary antioxidant capacity was measured using a commercially available Oxygen Radical Absorbance Antioxidant Assay measurement kit. At baseline, children with S-ECC had higher total antioxidant capacity (TAC) compared to the controls. Results A significant difference in total salivary antioxidant capacity between both groups was seen at baseline. At 3 months following, the total salivary antioxidant capacity of children treated for S-ECC was slightly higher than controls but had significantly reduced compared to baseline. At 6 months, there was no significant difference between both groups. Conclusion Within the limitations of our study, it can be concluded that the total salivary antioxidant capacity associated with children suffering from S-ECC is reduced after complete rehabilitation.

Dental Caries and Salivary Oxidative Stress: Global Scientific Research Landscape. Antioxidants (Basel) 2023; 12:antiox12020330. [PMID: 36829890 PMCID: PMC9952432 DOI: 10.3390/antiox12020330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/18/2023] [Accepted: 01/18/2023] [Indexed: 02/04/2023] Open
Abstract
This study aimed to analyze the research trends on salivary oxidative stress associated with dental caries and to perform bibliometric approaches for existing publications on this association. A search was performed using the Web of Science Core Collection, without any restriction of language or publication year. The number of periodicals with the most published articles in this theme, most published authors and keywords were mapped; other metrics were also evaluated such as the countries that have more research on the subject and the period in which there were more publications on the subject. During the knowledge mapping, the most frequent experimental designs were analyzed, type of saliva collection, stage of caries disease, evaluated oxidative parameters were retrieved and analyzed from each manuscript. Between the 43 selected articles, the Journal of Clinical Pediatric Dentistry was the periodical appearing the most with 4 published articles. The authors who published the most were Celec, P., Tothova, L., Hegde, A.M., Shetty, S., Antoniali, C., and Pessan, JP with three articles each, and a total of 180 keywords representing the evolution of the theme. India and Asia were found to be the country and continent with most publications, respectively. Most articles collected non-stimulated total saliva, with total antioxidant capacity being the parameter most often evaluated. The type of study that appeared the most was cross-sectional studies, and articles published in the period of 2017-2022 were the most frequent. Studies show that dental caries can be associated to the changes in salivary oxidative biochemistry with an increase in lipid peroxidation, a biomarker of oxidative damage, and an increase in antioxidant capacity in chronic caries, in response to cariogenic challenge. Some studies evidence the reduction of lipid peroxidation after treatment of the carious lesion. Our findings reveal worldwide research trends, as well as a clearer knowledge of the evolution and future scenarios of this issue, also showing the mechanisms associating dental caries with changes in salivary oxidative biochemical parameters are not clear.

Correlation of Carbonic Anhydrase VI Enzyme, Total Proteins, Antioxidant Levels of Saliva and Dental Caries in Caries-Free and Caries-Active Children - A Case-Control Study. Contemp Clin Dent 2022; 13:315-321. [PMID: 36686992 PMCID: PMC9855257 DOI: 10.4103/ccd.ccd_276_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 06/19/2021] [Accepted: 07/04/2021] [Indexed: 12/24/2022] Open
Abstract
Background and Objectives Factors in the biofilm influence the induction and advancement of the carious process. This study was done to relate and assess the levels of enzyme carbonic anhydrase VI, total protein, and antioxidants (superoxide dismutase [SOD], catalase, lipid peroxidase, and uric acid) in caries-free and caries-active children. Methods This case-control study comprised 60 children of age group 6-12 years who were evaluated for decayed missing filled teeth (dmft)/DMFT criteria and distributed into two groups: Group 1 - caries active (case) and Group 2 - caries free (control) for saliva collection with 30 participants in each of the above groups. Stimulated saliva was obtained, and the samples were then evaluated using biochemical lab tests. The data were then statistically evaluated using independent t-test. Results Catalase in the caries-free group was significantly higher, but the concentration of carbonic anhydrase (CAVI) enzyme, total protein, and other antioxidant enzyme activity was enhanced in caries-active children in which uric acid demonstrated a statistically significant difference with higher levels in caries-active group. Conclusion There is an increased concentration of CAVI enzyme in caries-active group and total protein showed a linear relation with caries activity. Antioxidant parameters such as SOD and lipid peroxidase were increased with caries activity. Uric acid was significantly higher in the caries-active group, whereas catalase showed an indirect relation with dental caries. Significant variations in the levels of these parameters imply that the levels of these components of saliva can act as strong markers of caries status in children.

Are Dental Caries Associated with Oxidative Stress in Saliva in Children and Adolescents? A Systematic Review. Metabolites 2022; 12:metabo12090858. [PMID: 36144263 PMCID: PMC9502212 DOI: 10.3390/metabo12090858] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 08/05/2022] [Accepted: 08/12/2022] [Indexed: 11/17/2022] Open
Abstract
Background: This systematic review aimed to assess whether dental caries is associated with oxidative salivary stress. Methods: The searches were carried out in electronic databases, including PubMed, Scopus, Web of Science, the Cochrane Library, LILACS, OpenGrey, and Google Scholar, without restrictions on the date of publication and language. The acronym PECO was used, in which the participants (P) were children and adolescents exposed (E) to dental caries compared (C) to those without dental caries, with the outcome (O) of modulation of oxidative biochemical parameters. After the search retrieval, the duplicates were removed, and the articles were evaluated by title and abstract, following the inclusion and exclusion criteria. Then, the papers were read and thoroughly assessed. After selection, the risk of bias assessment and qualitative synthesis were performed using the Newcastle-Ottawa Scale (NOS) for observational studies. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool was used to assess the level of evidence. Results: A total of 5790 studies were found, and 30 articles were considered eligible and were included for the qualitative synthesis and the level of evidence assessment. The studies showed an imbalance of the antioxidant and pro-oxidant parameters in individuals with dental caries, with primarily increases in both total antioxidant capacity and lipid peroxidation. Most articles showed a low risk of bias, having comparability as the main issue. When exploring through GRADE, a very low level of evidence was found. Conclusions: It was possible to observe an association between oxidative stress and dental caries, showing a disbalance of antioxidants and pro-oxidants, but the evidence level was still very low.

Abstract
AIM To evaluate the perspectives of parents and children on the impact of early childhood caries (ECC) on the oral health-related quality of life (OHQoF). MATERIALS AND METHODS About 400 children aged 3-5 years were recruited for the study. About 200 children who were caries-free were the controls for the study. The remaining 200 consisted of children who were diagnosed with ECC and required dental rehabilitation under general anesthesia. Oral health-related quality of life was recorded at baseline and 6 months after intervention using the Michigan oral health-related quality of life scale. Data were analyzed and evaluated using Statistical Package for Social Sciences (SPSS) Version 25.0. RESULTS Children with ECC were found to have a significantly lower oral health-related quality of life compared with caries-free children, and a statistically significant difference was seen between both groups. The main concern for both parents and children at baseline was pain at the first visit when the evaluation was done. After the intervention, a significant improvement in the oral health-related quality of life was seen. CONCLUSION Early childhood caries was found to have detrimental effects on the oral health-related quality of life. Full-mouth rehabilitation under general anesthesia was found to bring a significant improvement in the oral health-related quality of life. The perspectives of both parents and children were found to be similar. CLINICAL SIGNIFICANCE Early childhood caries has an impact on the lives of children and their parents. Oral health-related quality of life was low with children suffering from ECC. Full-mouth rehabilitation under general anesthesia can significantly improve the OHRQoL of children. Continuous monitoring of the children with regular follow-ups and parental education should be enforced to prevent the relapse of ECC.

Abstract
OBJECTIVE To assess the relationship between salivary biomarkers of oxidative stress and dental caries in children. METHODS Studies conducted in children up to 12 years old comparing salivary biomarkers of oxidative stress such as malondialdehyde (MDA), superoxide dismutase (SOD), uric acid, and total antioxidant capacity (TAC), considering children with dental caries lesions and caries-free ones were selected. In addition, salivary parameters such as salivary flow, pH, buffering capacity, calcium and total protein levels were evaluated. A systematic literature review was carried out in 8 databases. The standardized mean difference (SMD) was measured using inverse variance as a statistical method and random effects as an analysis model, corresponding to a 95% confidence interval (CI). RESULTS The TAC levels were higher in children affected by dental caries compared to caries-free ones (control group), regardless of age (SMD 2.66, CI 1.33, 3.98), or gender (SMD 0.98, CI 0.56, 1.39). When adjusted for normalized protein, MDA levels were lower in the dental caries group than in the control group (SMD -16.51, CI -29.02, -4.00), and SOD levels were higher in the dental caries group (SMD 5.09, CI 0.01.10.18). The total protein concentration in saliva of children with dental caries was higher than in the control group, regardless of age (SMD 0.98, CI 0.27, 1.69), or gender (SMD 0.77, CI 0.45, 1.10). The salivary parameters assessed had lower levels in children affected by dental caries (p < 0.05). CONCLUSIONS The levels of oxidative stress biomarkers and salivary parameters are altered in saliva of children with dental caries.

Salivary Redox Biomarkers in the Course of Caries and Periodontal Disease. APPLIED SCIENCES-BASEL 2020. [DOI: 10.3390/app10186240] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/15/2022]
Abstract
Caries are a pathological process of extracorporeal nature, characterized by demineralization of inorganic substances as well as proteolysis triggered by acids produced by bacteria present in dental plaque, as a result of metabolism of sugars of both external and internal origin. Periodontal disease, on the other hand, is a multifactorial degenerative disease associated with inflammation, involving a group of tissues that surround the dental cervix and root of the tooth. It is believed that one of the mechanisms in the etiopathogenesis of caries and periodontitis are disorders of local and/or general oxidative stress (OS) parameters. Numerous clinical studies have confirmed the relationship between oxidative stress markers and oral diseases. In most analyzed studies, technical and biological variability was so high that none of the markers so far has proven suitable for routine clinical use. The aim of systematic reviews of the literature is to present the existing studies on OS parameters, mainly concerning the activity of antioxidant enzymes in saliva of patients with caries and periodontitis.

Oxidative Stress Markers Differ in Two Placental Dysfunction Pathologies: Pregnancy-Induced Hypertension and Intrauterine Growth Restriction. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:1323891. [PMID: 32685085 PMCID: PMC7346256 DOI: 10.1155/2020/1323891] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 05/27/2020] [Accepted: 06/19/2020] [Indexed: 01/07/2023]
Abstract
Aim Pregnancy-induced hypertension (PIH) and intrauterine growth restriction (IUGR) are both multisystemic disorders of pregnancy that cause perinatal morbidity and mortality. Recently, researchers focused on the role of oxidative stress (OS) as a pathophysiological mechanism in the development of these pathologies. The aim of this study was to compare OS in placental-related pathologies (PIH and IUGR) and uncomplicated pregnancies. We also investigated which salivary OS markers reflect systemic oxidative status and which only reflect the state of the oral cavity. Material and Methods. A total of 104 pregnant women (n = 104; 27 with PIH, 30 with IUGR, and 47 controls) were evaluated. Malondialdehyde (MDA), total antioxidant capacity (ORAC), aldehyde dehydrogenase (ALDH), and activity of glutathione peroxidase (GPx) and glutathione transferase (GST) in plasma/whole blood and/or saliva were analysed. Dietary nutrient intake was calculated using a Semiquantitative Food Frequency Questionnaire (SFFQ). Oral health was assessed to eliminate patients with bleeding, severe periodontitis, and other dental pathologies. Results In the IUGR group, increased concentration of ORAC was observed both in saliva and plasma. Also, lower plasma levels of MDA in IUGR compared to the control group was detected. No sign of oxidative stress was confirmed in the PIH group. The examined groups did not differ regarding diet and markers of inflammation. ORAC in saliva was correlated with its level in plasma. No such correlations for MDA were observed. In the IUGR group, there were no differences in OS markers in plasma, but there was a lower ALDH level in the blood compared to the control group. It confirms OS occurrence in IUGR. In IUGR, a higher activity of salivary ALDH was probably due to worse oral health. Conclusion Oxidative stress differs between IUGR and PIH groups: the presence of oxidative stress was confirmed only in the IUGR group. Salivary ORAC can be used to estimate ORAC in plasma. The activity of salivary ALDH reflects the state of the oral cavity.
