Association between genetic factors and molar-incisor hypomineralisation or hypomineralised second primary molar: A systematic review.

To determine the association between genetic factors and molar-incisor hypomineralisation (MIH) and/or hypomineralised second primary molars by means of a systematic review.... A search was performed in Medline-PubMed, Scopus, Embase and Web of Science databases; manual search and search in gray literature were also performed. Selection of articles was performed independentl... Sixteen studies were included. There was an association between MIH and genetic variants related to amelogenesis, immune response, xenobiotic detoxification and other genes. Moreover, interactions bet... With very low or low certainty of evidence, an association was observed between MIH and SNPs in genes associated with amelogenesis, immune response, xenobiotic detox and ion transport. Interactions be...

Parameters associated with radiographic distal surface caries in the mandibular second molar adjacent to an impacted third molar.

To determine the risk factors for the development of radiographic distal surface caries (rDSC) in patients who attend routine dental check-ups during an era of National Institute for Health Care Excel... Radiographs taken during routine dental examinations involving 1012 patients from Manchester, UK were accessed. Clinical parameters, oral health, patient demographics, and socioeconomic factors were a... The detected rate of rDSC was 63.9% and rDSC was distributed homogenously across all five socioeconomic groups (p = 0.425). Risk factors associated with rDSC (p < 0.001) were identified as partially e... rDSC was significantly associated with the angulation of third molars, the compromised contact position of the adjacent third molar, the periodontal status of the distal aspect of the second molar and...

The impact of Anatomic Features of Asymptomatic Third Molars on the Pathologies of Adjacent Second Molars: A Cross-sectional Analysis.

We aimed to comprehensively examine how the anatomic characteristics of asymptomatic third molars (As-M3s) affect distal pathologies of adjacent second molars (Ad-M2s).... Patients with at least 1 quadrant having intact As-M3s and first and second molars were enrolled. Distal pathologies of Ad-M2s, including caries, pocket depth of 4 mm or more (PD4+), and alveolar bone... A total of 248 patients with their 805 quadrants were finally included in this cross-sectional study. The impacted and nonimpacted As-M3s elevated the risk of any distal pathology (caries, PD4+, or AB... The presence of As-M3 is a risk factor for Ad-M2 pathologies irrespective of impaction status. Within N-M3s, Ad-M2 pathologies are significantly influenced by anatomic characteristics such as regions ...

Masticatory performance with one missing molar.

This study aimed to evaluate masticatory performance in cases where one molar was missing.... Participants were 156 adults with one molar missing from their natural teeth, who were divided into group A (without prosthetic treatment) and group B (with prosthetic treatment). The non-missing side... AG was significantly greater on the dentate side (P < 0.001) and was significantly less in the A2 group when the first molar was missing (P = 0.002). The rate of decrease of AG was 11.1%, 14.3%, and 8... Masticatory performance appears to decrease even with only one missing molar. Although improvement is achieved by prosthetic treatment, performance remains inferior to that on the dentate side....

Two models were constructed: a one-year decision tree and a ten-year Markov model, each based on a hypothetical cohort of one thousand individuals through Monte Carlo simulation. Eight restorative str... Cost-effective treatments included HVGIC (%NMB = 0%/ 0%), encapsulated GIC (%NMB = 19.4%/ 19.7%), and encapsulated GIC + etch and rinse adhesive + composite (%NMB = 23.4%/ 24.5%) at 1 year and 10 year... Within the horizon and perspective analyzed, the most cost-effective treatment was encapsulated GIC restoration.... This study can provide information for decision-making....

Using machine learning to determine age over 16 based on development of third molar and periodontal ligament of second molar.

Having a reliable and feasible method to estimate whether an individual has reached 16 years of age would greatly benefit forensic analysis. The study of age using dental information has matured recen... The purpose of this study was to evaluate the development of the third molar using the Demirjian method (Demirjian... A total of 665 Chinese adolescents aged between 12 and 20 years were recruited for this study. The development of the second and third molars was evaluated by taking orthopantomographs. ML algorithms,... The study showed that SVM had the highest Bayesian posterior probability at 0.917 and a Youden index of 0.752. This finding provides an important reference for forensic identification, and the combina...

Factors affecting periodontal healing of the adjacent second molar after lower third molar surgery: a systematic review and meta-analysis.

This systematic review and meta-analysis aim to evaluate the effect modifiers which may influence the periodontal healing of the adjacent second molar after lower third molar surgery.... Prospective studies including patients with third molars requiring removal, with at least 6 months follow-up were considered. Outcomes were periodontal probing depth (PPD) reduction, final PPD, clinic... Fourteen studies were included in the quantitative synthesis. At 6 months, the PPD reduction was 1.06 mm (95% CI, 0.72 to 1.39 mm) and the remaining PPD was 3.81 mm (95% CI, 3.00 to 4.62 mm). Baseline... Lower third molar surgery results in a modest reduction in PPD, CAL, and ABD; however, periodontal defects still remain at 6 months and beyond. Baseline PPD is strongly correlated with final PPD. Whil... This study shows that lower third molar surgery results in modest improvement in periodontal parameters on adjacent second molars and identified factors such as baseline PPD which may affect the heali...
