Caries and periodontitis are the most prevalent oral diseases worldwide. Major factors contributing to the development of these oral conditions include poor oral hygiene, dental biofilm formation, high carbohydrates diet, smoking, other systemic diseases, and genetic factors. Various preventive measures have been established to mitigate the risk of caries and periodontal disease development. The present review aims to discuss the role of the probiotics Lactobacillus rhamnosus and Lactobacillus plantarum in the prevention and treatment of caries and periodontal diseases. The study was conducted in accordance with PRISMA guidelines and was registered on PROSPERO. The search involved PubMed, Web of Science, and Scopus and considered the PICO format. Studies were screened by two reviewers independently, and disagreements were solved by consensus with a third reviewer. Data extraction included details about the type of probiotics, strains, and purpose of administration. A total of 15 RCTs were included, of which just 1 was about tooth cavities. Overall, 87% of the included studies were good-quality papers regarding the Jadad Scale. Several studies agreed on the potential of probiotics L. rhamnosus and L. plantarum, both alone and combined, to prevent and improve clinical outcomes in caries and periodontal treatments, weaker evidence is provided for the microbiological benefit.

Diabetes can trigger an increase in cytokine levels leading to the production of C-reactive protein and fibrinogen. These molecules promote subclinical inflammation, causing the expression of adhesive molecules and endothelial dysfunction. Despite the lack of a comprehensive panel for single-nucleotide polymorphisms (SNPs) for interleukins associated with type 1 diabetes mellitus (T1DM), understanding the inflammatory role of SNPs is crucial because periodontitis, the sixth complication of diabetes, is influenced via these genetic variations. This review focuses on the interleukin levels in T1DM patients with and without periodontitis, with a particular focus on childhood and on SNPs when reported. A search of PubMed and Scopus identified 21 relevant studies from the past five years. Several ILs were analyzed, emphasizing that T1DM still needs to be thoroughly explored regarding an IL polymorphisms panel; however, the last five years have led to the increased independence of this condition, causing autonomous inflammatory effects, which require further investigation. The periodontitis and T1DM association in children and adolescents represents a severe gap in the literature that should be filled; this scarce presence of studies serves as motivation for further clinical research.

Inflammatory Bowel Diseases (IBDs), including Ulcerative Colitis (UC), Crohn's Disease (CD), Irritable Bowel Syndrome (IBS), and Coeliac Disease (CoD), primarily affect the intestinal tract but show some extra-intestinal manifestations affecting the skin, joints, liver, pancreas, and lungs. The aim of this survey was to define how often these intestinal conditions show oral manifestation. The study involved 46 patients of 56 recruited at the beginning, with a mean age of 42 ± 13.64 and a sex distribution of 67.4% (31) female and 32.6% (15) male. Everyone was sent a questionnaire of four multiple-choice questions about the type of their bowel disease, the time of the diagnosis, the major symptoms which led to the disease discover, and finally their oral symptoms. According to the results, 65.52% referred to oral manifestations, especially canker sores and burning sensation. The oral involvement suggests that multidisciplinary management and therapy are mandatory, with close monitoring and follow-up interfacing with other specialists. Finally, dental practitioners have to be aware of this possible oral effect in IBDs and CoD patients. [ABSTRACT FROM AUTHOR]

The exact knowledge of the mandibular canal position is fundamental in oral surgery and implantology. Clinicians have to be extremely cautious when operating in close proximity to this structure in order to avoid damaging the neurovascular bundle. Several anatomical variations of the mandibular canal have been described in the literature, such as bifid or trifid structures. The use of cone-beam computed tomography (CBCT) offers a detailed representation of the inferior alveolar nerve path, albeit with some difficulties of identification when dental implants or metal prosthesis are present. The aim of this study is to retrospectively evaluate the prevalence and location of bifid/trifid mandibular canals (BMC/TMC) by CBCT in Italian patients. The screening phase involved 584 patients, only 238 enrolled (97 men; 141 women), with an average age of 51 ± 17.20. A total of 36 patients (15.25%) showed at least one bifid mandibular canal; only 2 patients (0.84%) showed a trifid mandibular canal. Overall, 12 patients (5.04%) presented this variation bilaterally. There was no association with the sex of the enrolled sample. In conclusion, the presence of BMCs and TMCs may be considered as a risk factor for the onset of neurovascular complications. Being aware of changes in the mandibular canal helps clinicians to prevent inferior alveolar nerve impairments that may occur during oral surgery and implantology. [ABSTRACT FROM AUTHOR]

Meckel syndrome (MKS) is a lethal, autosomal recessive, congenital syndrome caused by mutations in genes that encode proteins structurally or functionally related to the primary cilium. MKS is a malformative syndrome, most commonly characterized by occipital meningoencephalocele, polycystic kidney disease, liver fibrosis, and post- and (occasionally) preaxial polydactyly. To date, more than 10 genes are known to constitute the molecular background of MKS, displaying genetic heterogeneity. Individuals with MKS may resemble some phenotypic features of Joubert syndrome and related disorders, thus making diagnostic setting quite challenging. Here, we systematically reviewed the main clinical and genetic characteristics of MKS and its role among ciliopathies. [ABSTRACT FROM AUTHOR]
