Abstract
Salivary biomarkers can improve the efficacy, efficiency, and timeliness of oral and maxillofacial disease diagnosis and monitoring. Oral and maxillofacial conditions in which salivary biomarkers have been utilized for disease-related outcomes include periodontal diseases, dental caries, oral cancer, temporomandibular joint dysfunction, and salivary gland diseases. However, given the equivocal accuracy of salivary biomarkers during validation, incorporating contemporary analytical techniques for biomarker selection and operationalization from the abundant multi-omics data available may help improve biomarker performance. Artificial intelligence represents one such advanced approach that may optimize the potential of salivary biomarkers to diagnose and manage oral and maxillofacial diseases. Therefore, this review summarized the role and current application of techniques based on artificial intelligence for salivary biomarker discovery and validation in oral and maxillofacial diseases.

Arch Oral Biol 2023; 151:105714. [PMID: 37141746 DOI: 10.1016/j.archoralbio.2023.105714] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 04/25/2023] [Accepted: 04/26/2023] [Indexed: 05/06/2023]
Abstract
OBJECTIVES This study aimed to explore that whether interactions between Prevotella denticola and Streptococcus mutans could promote the establishment of hypervirulent biofilms on teeth surface and eventually influence the occurrence and development of caries. DESIGN Based on single-species biofilms of either P. denticola or S. mutans, and dual-species biofilms of both bacteria, we compared the virulence properties associated with cariogenicity in vitro, including carbohydrate metabolism and acid productivity, synthesis of extracellular polysaccharides, biomass and architecture of biofilms, level of enamel demineralization and expression of virulence genes associated with carbohydrate metabolism and adhesion in S. mutans. RESULTS The data demonstrated that, compared to single-species of above two taxa, dual-species produced lactate by metabolizing carbohydrates at a higher level during the observation period. Moreover, dual-species biofilms accrued more biomass and exhibited more dense microcolonies and abundant extracellular matrix. And it's noticeable that the level of enamel demineralization in dual-species biofilms was more augmented than that of single-species. In addition, the presence of P. denticola induced the expression of virulence genes gtfs and gbpB in S. mutans. CONCLUSIONS Symbiotic relationship between P. denticola and S. mutans enhances caries-associated virulence of plaque biofilms, which might provide new strategies for effective prevention and treatment of caries.

Song Z, Fang S, Guo T, Wen Y, Liu Q, Jin Z. Microbiome and metabolome associated with white spot lesions in patients treated with clear aligners. Front Cell Infect Microbiol 2023; 13:1119616. [PMID: 37082715 PMCID: PMC10111054 DOI: 10.3389/fcimb.2023.1119616] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Accepted: 03/17/2023] [Indexed: 04/07/2023] Open
Abstract
White spot lesions (WSLs) have long been a noteworthy complication during orthodontic treatment. Recently, an increasing number of orthodontists have found that adolescents undergoing orthodontic treatment with clear aligners are at a higher risk of developing WSLs. The oral microbiota and metabolites are considered the etiologic and regulatory factors of WSLs, but the specific impact of clear aligners on the oral microbiota and metabolites is unknown. This study investigated the differences in the salivary microbiome and metabolome between adolescents with and without WSLs treated with clear aligners. Fifty-five adolescents (aged 11-18) with Invisalign appliances, 27 with and 28 without WSLs, were included. Saliva samples were analyzed using 16S rRNA gene sequencing and ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS); the data were further integrated for Spearman correlation analysis. The relative abundances of 14 taxa, including Actinobacteria, Actinomycetales, Rothia, Micrococcaceae, Subdoligranulum, Capnocytophaga, Azospira, Olsenella, Lachnoanaerobaculum, and Abiotrophia, were significantly higher in the WSL group than in the control group. Metabolomic analysis identified 27 potential biomarkers, and most were amino acids, including proline and glycine. The metabolites were implicated in 6 metabolic pathways, including alanine, aspartate and glutamate metabolism; glycine, serine and threonine metabolism; and aminoacyl-tRNA biosynthesis. There was a correlation between the salivary microbial and metabolomic datasets, reflecting the impact of clear aligners on the metabolic activity of the oral flora. A concordant increase in the levels of Lachnoanaerobaculum, Rothia, Subdoligranulum and some amino acids had predictive value for WSL development. In summary, when adolescents undergo long-term clear aligner therapy with poor oral hygiene habits, clear aligners can disrupt the balance of the oral microecosystem and lead to oral microbiota dysbiosis, thereby increasing the risk of developing WSLs. Our findings might contribute to the understanding of the pathogenesis of WSLs and provide candidate biomarkers for the diagnosis and treatment of WSLs associated with clear aligners.

Angarita‐Díaz MDP, Fong C, Bedoya‐Correa CM, Cabrera‐Arango CL. Does high sugar intake really alter the oral microbiota?: A systematic review. Clin Exp Dent Res 2022; 8:1376-1390. [PMID: 35946056 PMCID: PMC9760141 DOI: 10.1002/cre2.640] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Revised: 07/07/2022] [Accepted: 07/12/2022] [Indexed: 01/26/2023] Open
Abstract
OBJECTIVES Diet is one of the main factors influencing the diversity and interactions of the oral microbiota. The purpose of this study is to determine the impact of sugar intake on the microbial diversity and bacteria that predominate under these conditions. MATERIAL AND METHODS A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guide, using the PubMed, Scopus, and Science Direct databases and combinations of the words "microbiota," "microbiology," "bacteria," "sugars," "dysbiosis," "caries," "microbiome," "oral microbial," and "oral microbiota profile pattern." The selection criteria included year, language, type of publication, comparison of microbiota during low and high sugar intake, and bacterial identification by molecular sequencing of the 16S subunit of ribosomal RNA. RESULTS Out of a total of 374 papers that came up after the initial search, 8 met the criteria for this review. The papers included research on populations comprising children, young adults, and adults, with most of the studies reporting selection criteria for the participants and using validated instruments to determine sugar intake. Apart from one study, all others reported for high sugar intake conditions a significant decrease in microbial diversity of the oral microbiome and the predominance of several bacterial genera or species, including Streptococcus, Scardovia, Veillonella, Rothia, Actinomyces, and Lactobacillus. CONCLUSIONS Sugar-rich diets have a significantly unfavorable effect on the diversity and balance of oral microbiota; however, further studies are required to determine the exact role of sugar in microbial interactions.

The Influence of Parenting Styles on Eating Behavior and Caries in Their Children: A Cross-Sectional Study. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9060911. [PMID: 35740848 PMCID: PMC9221745 DOI: 10.3390/children9060911] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 06/12/2022] [Accepted: 06/16/2022] [Indexed: 12/23/2022]
Abstract
The type of parenting style influences the way children cope with problems and can create states of anxiety that can even alter their eating habits, which can cause problems in their oral health. The present study aimed to find out which parenting style is more favorable for the oral health of their children. In this cross-sectional study, 186 children (aged 8-15 years) were examined to assess the mean Decayed/Missing/Filled teeth (DMFT + dmft) index, and they were asked to complete the State-Trait Anxiety Inventory, the Parenting Style Scale, and questions about their oral hygiene habits. On the other hand, their parents answered the Parental Feeding Style Questionnaire and the Children's Eating Behavior Questionnaire. Results showed that a worse oral health status was associated with a higher state of anxiety, more overeating, more emotional eating, and higher psychological control. A higher rate of missing teeth was associated with increased undereating and overeating. Emotional eating was positively related to psychological control. State of anxiety, overeating, and parental psychological control predicted 24.6% of DMFT + dmft. In addition, emotional eating had a moderating effect in DMFT + dfmt only in those with low levels of affection and communication. In conclusion, high psychological control and low levels of parental affection and communication will increase the state of anxiety in children, influencing their caries rate.

Comparison of the Oral Microbiota Structure among People from the Same Ethnic Group Living in Different Environments. BIOMED RESEARCH INTERNATIONAL 2022; 2022:6544497. [PMID: 35800217 PMCID: PMC9256442 DOI: 10.1155/2022/6544497] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 05/01/2022] [Accepted: 05/03/2022] [Indexed: 11/20/2022]
Abstract
The characteristics of the oral microbiota may depend on oral health, age, diet, and geography, but the influence of the geographic setting on the oral microbiota has received limited attention. The characteristics of oral microbiota have been reported to differ between urban and rural environments. In order to minimize the influence of genetic background, we recruited 54 volunteers from the same ethnic group, living in urban and rural areas of Gansu Province, China. We collected dental plaque samples and divided them into four groups according to the participant's area of residence and dental caries status. We sequenced the 16S rRNA of these samples using the Pacific Biosciences sequencing platform and analyzed the correlation between the geographic area and the characteristics of the oral microbiota. Analysis of the alpha and beta diversity revealed that there were significant differences in diversity and composition of dental plaque microflora among the four groups. Cluster analysis revealed that geographic area played an important role in determining the oral microbiota. Network analysis of oral microorganisms showed that geographic differences had major influence on the composition characteristics and internal structure of oral microorganisms. We found that some dominant strains which may play a key role in maintaining oral health, such as Streptococcus oralis, Capnocytophaga sputigena, Porphyromonas catoniae, Corynebacterium matruchotii, Haemophilus parainfluenzae, and Prevotella loescheii, were less affected by the geographic setting. These results provide a deeper understanding of factors influencing the composition of the oral microbiota and could contribute to early diagnosis and effective prevention of dental caries in different settings.

Interference of dietary polyphenols with potentially toxic amino acid metabolites derived from the colonic microbiota. Amino Acids 2021; 54:311-324. [PMID: 34235577 DOI: 10.1007/s00726-021-03034-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Accepted: 06/24/2021] [Indexed: 02/07/2023]
Abstract
Each day, varying amounts of undigested or partially digested proteins reach the colon where they are metabolized by the microbiota, resulting in the formation of compounds such as ammonia, p-cresol, skatole, phenol, indole, and hydrogen sulfide (H2S). In farm animals, the excessive production of these metabolites can affect the quality of meat and milk and is a source of contaminating emissions from animal manure. In humans, their accumulation is potentially harmful, and it has been proposed that they could be involved in the development of pathologies such as colorectal cancer and ulcerative colitis, among others. This review assesses the evidence supporting the use of dietary polyphenols to reduce the production of these metabolites. Most studies have used condensed (proanthocyanidins) or hydrolyzable (ellagitannins and gallotannins) tannins, and have been carried out in farm animals. Several show that the administration of tannins in pigs, chicken, and ruminants decreases the levels of ammonia, p-cresol, skatole, and/or H2S, improving meat/milk quality and reducing manure odor. Direct application of tannins to manure also decreases ammonia emissions. Few studies were carried out in rats and humans and their results confirm, to a lesser extent, those reported in farm animals. These effects would be due to the capacity of tannins to trap ammonia and H2S, and to modify the composition of the microbiota, reducing the bacterial populations producing metabolites. In addition, PACs prevent p-cresol and H2S-induced alterations on intestinal cells in vitro. Tannins, therefore, appear as an interesting tool for improving the quality of animal products, human health, and the harmful emissions associated with breeding.
