This systematic review aims to investigate the microbial basis underlying the association between oral microbiota and colorectal cancer. A comprehensive search was conducted across four databases, encompassing potentially relevant studies published up to April 2024 related to the PECO question: "Is there a differentiation in oral microbial composition between adult patients diagnosed with colorectal cancer compared to healthy patients?". The Newcastle‐Ottawa Scale was used to evaluate the quality of the studies included. The level of evidence was assessed through the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) tool. Sixteen studies fulfilled the eligibility criteria. Based on low to moderate evidence profile, high levels of certain subspecies within Firmicutes (such as Streptococcus anginosus, Peptostreptococcus stomatis, S. koreensis, and S. gallolyticus), Prevotella intermedia, Fusobacterium nucleatum, and Neisseria oralis were found to be associated with colorectal cancer. Conversely, certain bacteria (e.g., Lachnospiraceae, F. periodonticum, and P. melaninogenica) could exert a symbiotic protective effect against colorectal cancer. Based on existing evidence, it appears that variations in oral microbiota composition exist among individuals with and without colorectal cancer. However, further research is necessary to determine the mechanisms of oral dysbiosis in colorectal carcinogenesis. [ABSTRACT FROM AUTHOR]

Background: Halitosis in children implies psychosocial repercussions. Risk factors associated with this condition are unclear, and detection methods are inaccurate. Aim: To quantify the levels of sulfur‐like compounds in children with asthma and healthy children from a novel validated assay, and to establish the risk factors related to halitosis. Design: One hundred and twenty‐eight individuals (63 healthy and 65 asthmatic) from 3 to 17 years of age were tested using a passive colorimetric sensor to measure the levels of sulfur‐like compounds in breath and saliva. Information was collected on oral hygiene habits, gingival and dental health, breathing type, and dental malocclusion. Results: The mean values of hydrogen sulfide were 4.0 ± 6.8 and 19.7 ± 12.2 ppbv (parts per billion in volume) in the control and asthmatic groups, respectively (p <.001). The presence of higher concentrations of sulfur compounds was significantly associated (p <.05) with the presence of gingival inflammation, tongue coating, dental plaque, mouth breathing, hypomineralization, age, tongue brushing, and the use of dental floss. Conclusion: The level of sulfur in breath and saliva was significantly higher in patients with asthma. These results can serve as a precedent to raise awareness among paediatricians and parents about oral hygiene care in children and adolescents. [ABSTRACT FROM AUTHOR]

The present case report describes the orthodontic management of a patient who presented with a skeletal Class III malocclusion combined with other dental anomalies. The malocclusion was complicated by agenic maxillary lateral incisors and a lower right second premolar, in company with the transposition of the maxillary canines and premolars.

Background/objective Patient compliance during orthodontic treatment is one of the factors that most affects success in the final result. The use of removable appliances is frequent at an early age and the monitoring of its use is essential to assess the collaboration of the patient. The aim of this study was to establish the effectiveness of microsensors included in removable appliances during orthodontic treatment or in the retention phase to enable a reliable and individualized follow-up of the patient. Search methods The article search was carried out in various electronic databases and journals without any language restrictions. Selection criteria Studies using microsensors into removable appliances were selected with the key selection criterion of a minimum follow-up of 4 weeks. Data collection and analysis The quality of the studies included was evaluated using the Cochrane scale for the randomized controlled trials and the Newcastle Ottawa Scale for control–case, cohort, and transversal studies. The mean of the differences with a 95% confidence interval was expressed for the continuous data. Results Twenty-nine full-text articles were analysed and included in the qualitative synthesis. In general, the mean daily wear time of removable appliances measured objectively was less than the time that the professional had predetermined. Conclusions The use of microsensors as an objective measurement method enhances communication and boosts confidence in the orthodontist–patient relationship. More random clinical studies with temperature sensors are needed to establish to what extent they influence the orthodontic outcome. Registration PROSPERO (CRD42019120525). [ABSTRACT FROM AUTHOR]
