Abstract
Background Temporomandibular joint disorders (TMD) are highly prevalent among people. Numerous investigations have revealed the impact of gut microbiota in many diseases. However, the causal relationship between Temporomandibular joint disorders and gut microbiota remains unclear. Methods Genome-Wide Association Studies (GWAS) refer to the identification of sequence variations, namely single nucleotide polymorphisms (SNPs), existing across the entire human genome. GWAS data were collected on gut microbiota and TMD. Then, instrumental variables were screened through F-values and removal of linkage disequilibrium. These SNPs underwent mendelian analysis using five mathematical models. Sensitivity analysis was conducted to further verify the stability of the results. Pathogenic factors of TMD mediate the causal relationship between gut microbiota and TMD were explored through a two-step Mendelian randomization analysis. Finally, reverse mendelian analysis was conducted to account for potential reverse effects. Results The analysis of the data in this article suggests that some gut microbiota, including Coprobacter, Ruminococcus torques group, Catenibacterium, Lachnospiraceae, Turicibacter, Victivallis, MollicutesRF9, Methanobacteriales, Methanobacteriaceae, FamilyXI, Methanobacteria were identified as risk factors, while Peptococcaceae provides protection for TMD. Conclusion The research reveals the relation of gut microbiota in TMD. These findings provide insights into the underlying mechanisms and suggest potential therapeutic strategy.

[PMID: 38319548 DOI: 10.1007/s10266-023-00890-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 12/11/2023] [Indexed: 02/07/2024]
Abstract
The management of malocclusion has developed greatly in terms of treatment simulation and biomechanics, but treatment duration has been a great concern to the clinician as well as the patient. 1-25dihydroxycholecalciferol (biologically active form of Vitamin D) stimulates both osteoclasts and osteoblasts and was found to be the most significant in Orthodontic Tooth Movement acceleration. Inflammatory cytokines like IL-17A also play an important role in osteoclastogenesis and can enhance the rate of Orthodontic Tooth Movement.To perform a simultaneous evaluation of pro-inflammatory salivary cytokine IL-17A and salivary 1-25dihydroxycholecalciferol and to correlate their role on orthodontic tooth movement.A prospective cohort study was conducted among n = 97 patients. Saliva samples were collected from the patients at three phases of the orthodontic treatment, centrifuged and stored at 4℃ for evaluation of salivary 1-25dihydroxycholecalciferol levels and Pro-inflammatory cytokine IL-17A using ELISA.The mean salivary 1-25dihydoxycholecalciferol levels were 41.250 ng/ml, 33.246 ng/ml and 35.043 ng/ml during the initial phase, lag phase and post lag phase of orthodontic treatment. The mean pro-inflammatory cytokine IL-17 A levels were 107.79 pg/ml, 102.98 pg/ml and 66.156 pg/ml during the initial phase, lag phase and post lag phase of orthodontic treatment. There was a correlation between the salivary 1-25dihydroxycholecalciferol level and salivary cytokine IL-17A levels during the various phases of orthodontic treatment using Spearman's correlation rho test and linear regression analysis. There was no significant difference (p > 0.05) between 1-25dihydroxycholecalciferol levels and gender during the various phases (initial phase, lag phase and post lag phase) of Orthodontic treatment.There was a negative correlation between salivary 1-25dihydroxycholecalciferol level and salivary cytokine IL-17A levels during the various phases of orthodontic treatment. The level of 1-25dihydroxycholecalciferol and salivary cytokine IL-17A have been quantified during the various phases of Orthodontic treatment and this can be used clinically for the supplementation of Vitamin D in patients with low vitamin D levels and can enhance the treatment duration for the patient with less damaging effects to the surrounding tissues.

Abstract
BACKGROUND The maternal diet is essential to offspring development, but the specific effects on tooth morphology are still unknown. The aim of this study was to evaluate the effects of altering maternal calcium (Ca) and phosphorus (P) supplementation during gestation and lactation on offspring dentition. METHODS Pregnant mice were fed an experimental diet containing a threefold increase in Ca and a threefold decrease in P compared to the standard mouse chow diet at embryonic Day 0.5 (E0.5). Offspring mice were maintained on standard or experimental diets from post-natal Day 0 to weaning, then fed control diets until 6 weeks of age. Six-week-old offspring heads were collected and scanned using micro-computed tomography. Dental morphometrics of offspring maxillary and mandibular first and third molars (n = 5-6 per diet/per sex) were determined. A two-way ANOVA test was employed to verify the existence of any significant differences between groups. The significance level was set at P < .05. RESULTS A two-way ANOVA revealed a statistically significant interaction between the effects of diet and sex on the upper and lower dentition. Moreover, experimental diet-fed female offspring exhibited smaller molars with shorter mesiodistal width and larger pulp chambers relative to controls, while experimental diet-fed male offspring possessed larger molars with wider mesiodistal width and smaller pulp chambers. CONCLUSION Our findings reveal that altering the maternal and offspring dietary Ca:P ratio during gestation, lactation and weaning led to significant, sex-specific changes in the offspring dentition. The differences in dentition appeared to be correlated with the sex-specific changes in the craniofacial skeleton.

Role of vitamin D for orthodontic tooth movement, external apical root resorption, and bone biomarker expression and remodeling: A systematic review. Korean J Orthod 2024; 54:26-47. [PMID: 38268460 PMCID: PMC10811359 DOI: 10.4041/kjod23.064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 08/04/2023] [Accepted: 09/18/2023] [Indexed: 01/26/2024] Open
Abstract
Objective : This systematic review aimed to evaluate the correlation between vitamin D levels and the rate of tooth movement, external apical root resorption, bone biomarker expression, and bone remodeling. Methods : Three databases (PubMed, Scopus, and Web of Science) were systematically searched from inception until 14th March 2023 to identify studies investigating the correlation between orthodontic tooth movement and vitamin D in animals and humans. The quality assessment was made in accordance with the Joanna Briggs Institute Critical Appraisal Checklist. Results : Overall, 519 records were identified, and 19 were selected for the qualitative synthesis. Eleven studies investigated the effect of local administration (injections in the periodontal ligament, to the gingiva distal to the teeth, or submucosae palatal area) and systemic administration (oral supplementation) of vitamin D on tooth movement, external apical root movement, pro-inflammatory cytokines, and bone remodeling factors. The remaining eight studies investigated the correlation between serum vitamin D levels and salivary vitamin D levels on bone turnover markers and tooth movement. Conclusions : The findings of this systematic review support that vitamin D3 local injections might increase the rate of tooth movement via the receptor activator of the nuclear factor-kB/osteoprotegerin axis. However, the non-uniform study designs and the different protocols and outcome methods make it challenging to draw reliable conclusions.

Abstract
The nutritional needs already increased by adolescent growth, activity, and stress are further exacerbated by the physical, physiological, and psychological stress that orthodontic treatment causes. Hence, the main objective of this systematic review was to analyze the relationship between adequate nutrition and its impact on orthodontic treatment success rates. Using relevant keywords, reference searches, and citation searches, the databases such as PubMed-Medical Literature Analysis and Retrieval System Online, Web of Science, Cochrane, and Scopus were all searched. "Diet," "Minerals," "Nutrition," "Orthodontics," and "Vitamins" were the search terms used to scour the database. The 10 studies selected for the systematic review and subsequent meta-analysis could not conclusively establish the correlation between proper nutrition and its impact on orthodontic treatment of the patient. There was virtually little connection between patients' dietary intake and the effectiveness of their orthodontic treatment. Additionally, a direct causal link between the two could not be established legitimately because the majority of the studies reviewed only noted an impact during the early stages of the treatment.

[PMID: 37241010 DOI: 10.3390/jpm13050840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 05/12/2023] [Accepted: 05/15/2023] [Indexed: 05/28/2023] Open
Abstract
OBJECTIVE To investigate the influence of endogenous and exogenous neuroendocrine analogues on the range and motion of jaw movement, mandibular growth, and factors affecting condylar guidance in patients with temporomandibular joint disorders using clinical assessment and radiographic imaging. MATERIAL AND METHODS Eligible articles were extracted from eleven databases in early 2023 and screened following PRISMA protocols. Certainty of evidence and potential biases were assessed using the GRADE approach. RESULTS Nineteen articles were screened, with four deemed to be of high quality, eight of moderate quality, and the remaining seven of low to very low quality. Corticosteroids improve maximal incisal opening but not TMJ disorder symptoms. Higher doses worsen jaw movement and cause osseous deformity. Growth hormone affects occlusal development, and delayed treatment affects arch width. Sex hormone correlation with TMJ disorder is complex, with some studies showing a correlation between menstrual cycle phases and pain/limited mobility. CONCLUSIONS The evaluation of neuroendocrine influencers in relation to jaw movement in patients with temporomandibular joint disorders involves the complex interplay of potentially confounding factors that each require careful consideration to ensure accurate diagnoses and evaluations.
