The role of probiotics in preventing dental caries: a systematic review of clinical evidence
No full textBackground: Probiotics have emerged as a promising adjunctive strategy for oral health, particularly in the prevention of dental caries, a multifactorial disease driven by ecological imbalances in the oral microbiome.
Methods: A systematic search of PubMed, Scopus, and Web of Science was conducted for studies published between January 2014 and January 2025, focusing on the use of probiotics for caries prevention in children and young adults. Clinical trials and observational studies were included, and a qualitative synthesis was performed based on the extracted outcomes.
Results: Twenty-one studies met the inclusion criteria. Most clinical trials reported a significant reduction in Streptococcus mutans levels following administration of probiotic strains, particularly Lactobacillus paracasei, Lactobacillus rhamnosus, and Bifidobacterium lactis. Several studies also demonstrated a decreased incidence of new carious lesions and an improvement in salivary immune markers. However, a minority of studies found no significant effect, highlighting potential variability due to strain type, dosage, delivery method, and population characteristics.
Conclusion: The current evidence supports the potential of specific probiotic strains to reduce cariogenic bacterial loads and contribute to caries prevention. Further standardized, long-term trials are needed to clarify the most effective formulations and regimens for clinical application

Questo studio si propone di presentare una tecnica per la preparazione e l’otturazione dei canali radicolari con apici di dimensioni superiori a 60 centesimi di millimetro, utilizzando strumenti canalari specifici.
MATERIALI E METODI: Lo studio è focalizzato sull’uso degli strumenti rotanti in nichel-titanio (Ni-Ti) per preparare e otturare canali radicolari con apici di dimensioni considerevoli (oltre i 60 centesimidi millimetro). La lega Ni-Ti, nota per caratteristiche come memoria di forma e superelasticità, ha rivoluzionato l’endodonzia, rendendola più certa e ripetibile. L’intervento endodontico è stato eseguito con successo utilizzando gli strumenti rotanti in nichel-titanio (Ni-Ti) e la tecnica Microseal per la preparazione e l’otturazione dei canali radicolari con apici di dimensioni considerevoli. Il blocco del nervo alveolare inferiore è stato ottenuto con mepivacaina con adrenalina 1:100000, e l’isolamento del campo operatorio è stato realizzato con l’uso della diga di gomma. La procedura di apertura della camera pulpare è stata eseguita tramite frese diamantate rotanti ad alta velocità, seguita dall’accesso ai canali radicolari. Durante la strumentazione canalare con il sistema Mtwo®, è stata utilizzata un’irrigazione alternata con ipoclorito di sodio al 5% e acido etilenodiamminotetraacetico al 17%. Per la preparazione dei canali, è stata impiegata una sequenza di strumenti Mtwo® con diversi diametri e conicità. Per raggiungere gli apici di grosse dimensioni, è stata sviluppata una tecnica innovativa chiamata “GC home made”, che prevede il taglio progressivo della punta di uno strumento Mtwo®. Dopo la preparazione, l’otturazione è stata eseguita utilizzando la tecnica Microseal con guttaperca e coni di guttaperca. Lo studio è stato applicato a un caso clinico di ritrattamento endodontico su un molare inferiore e ha dimostrato l’efficacia della tecnica “GC home made” nella preparazione e nell’otturazione dei canali con apici di grosse dimensioni. Questo approccio offre un’alternativa innovativa e promettente nella pratica endodontica.
RISULTATI: La tecnica è stata efficace nel raggiungere e sigillare l’apice dei canali. Complessivamente, l’approccio ha garantito un trattamento endodontico accurato e avanzato, dimostrando l’efficacia della combinazione di strumenti canalari scelti e della tecnica “GC home made” nella gestione di apici di grosse dimensioni.
CONCLUSIONI: La tecnica descritta si è dimostrata efficace nel trattamento di canali con apici di grosse dimensioni, consentendo una preparazione e un’otturazione adeguate. Tale approccio potrebbe migliorare il successo clinico nei casi con anatomia radicolare complessa.
SIGNIFICATO CLINICO: Il materiale degli strumenti canalari utilizzati offre flessibilità, efficienza e capacità di taglio durante la strumentazione canalare grazie alla sua memoria di forma e superelasticità. Tuttavia, ci sono alcuni rischi come la frattura degli strumenti stessi sotto carichi maggiori e l’accumulo di fatica. Sono importanti una tecnica operativa corretta e il controllo del carico applicato. L’otturazione canalare è cruciale per il successo endodontico, con enfasi sul sigillo tridimensionale e la scelta accurata del limite apicale.OBJECTIVES Endodontics has undergone great changes with the introduc tion of increasingly precise in strumentation with state-of-the art mechanics, making it more reliable and predictable. Howev er, the management of canals with large apices remains a chal lenge. This study aims to present a technique for the preparation and obturation of root canals with apices larger than 60 hundredths of a millimeter, using Mtwo® in struments. MATERIALS AND METHODS This study focuses on the use of nickel-titanium (Ni-Ti) rotary in struments to prepare and obtu rate root canals with apices of considerable size (over 60 hun dredths of a millimeter). The Ni-Ti alloy, known for characteristics such as shape memory and su perelasticity, has revolutionized endodontics, making it more cer tain and repeatable. Endodontic surgery was successfully per formed using the Microseal tech nique with gutta-percha and Ni Ti cones. The study was applied to a clinical case of endodontic retreatment on a lower molar and demonstrated the effectiveness of the “GC home made” tech nique in the preparation and ob turation of canals with large api ces. This approach offers an in novative and promising alterna tive in endodontic practice. RESULTS formed using nickel-titanium (Ni Ti) rotary instruments and the Microseal technique for prepara tion and obturation of root canals with sizable apices. Blockage of the inferior alveolar nerve was achieved with mepivacaine with adrenaline 1:100000, and isola tion of the operative field was achieved with the use of rubber dam. The pulp chamber opening procedure was performed using high-speed rotary diamond burs, followed by root canal access. During root canal instrumenta tion with the Mtwo® system, al ternating irrigation with 5% sodi um hypochlorite and 17% eth ylene diamine tetraacetic acid was used. For canal preparation, a sequence of Mtwo® instru ments with different diameters and taper was used. To reach large apices, an innovative tech nique called “GC home made” was developed, which involves progressive cutting of the tip of an Mtwo® instrument. After preparation, obturation was per The technique was effective in reaching and sealing the apex of the canals. Overall, the compre hensive approach ensured accu rate and advanced endodontic treatment, demonstrating the ef fectiveness of the combination of selected root canal instruments and the “GC home made” tech nique in managing large apexes. CONCLUSIONS The described technique proved effective in the treatment of ca nals with large apices, allowing febbraio/2025 DENTAL CADMOS for adequate preparation and ob turation. This approach could im prove clinical success in cases with complex root anatomy. CLINICAL SIGNIFICANCE The material of the root canal in struments used offers flexibility, efficiency, and cutting ability during root canal instrumentation due to its shape memory and su perelasticity. However, there are some risks such as the instru ments fracture under lower loads and fatigue accumulation. Proper operative technique and control of the applied load is important. Root canal obturation is crucial to endodontic success, with em phasis on three-dimensional sealing and careful selection of the apical limit

A Newly Developed Orthodontic-Logopedic Screening Procedure for Myofunctional Dysfunctions—A Pilot Study
Full text linkInterdisciplinary, patient-specific cooperation between orthodontics and speech therapy plays an important role in the therapy of myofunctional dysfunctions. The following orthodontic-logopedic screening procedure is intended to objectify the diagnosis of such dysfunctions and the progress of therapy. A diagnostic questionnaire was prepared based on existing diagnostic questionnaires for myofunctional dysfunction. It contains 32 questions, with a clinical weighting of 0 to 50 points in total. This results in a point score. The lower the score is, the lower the need for therapy is. The study included 108 patients between the ages of 6 and 50 years. After screening, the patient population was divided into Group 0 (score < 15; no speech therapy need; n = 36) and Group 1 (score ≥ 15; a speech therapy need; n = 72). Group 1 was additionally randomized into Subgroups A (with speech therapy; n = 36) and B (without speech therapy; n = 36). After a treatment interval of 6 months, all patients in Group 1 were examined again with the help of the screening procedure. Statistical analysis (SPSS) and significance testing (Mann–Whitney U test) were performed. At baseline, there was no significant difference between patients in Subgroups A and B (p = 0.157). Subgroup A had a median score of 25, and Subgroup B had a median score of 30. However, after the treatment interval, a significant improvement (p = 0.001) for Subgroup A with a median score of 11 (mean score difference = 14.67) over Subgroup B with a median score 23 (mean score difference of 7.08) was observed. The developed screening procedure was shown to be equally applicable to all patients and treatment providers. With the help of the scores in point form, the need for speech therapy and the progress of such therapy can be objectified

The effect of periodontal treatment on Helicobacter pylori-infection: a systematic review
Full text linkHelicobacter pylori (H. pylori), a bacterium widely distributed in the world's population, represents the most common cause of chronic gastritis and the main risk factor for stomach cancer. The main obstacle to the eradication of H. pylori is antibiotic resistance, therefore new therapeutic strategies are necessary. Recently, periodontitis has been correlated with several systemic diseases, including H. pylori-associated gastritis. The common pathogenetic link between these two diseases is the chronic inflammation induced by bacteria in the oral cavity and stomach. This systematic review aims to evaluate the benefits of non-surgical periodontal treatment (NSPT) on Helicobacter pylori eradication. PubMed, Scopus, Web of Science, and Cochrane were searched using the MESH terms “Helicobacter pylori” and “periodontal treatment”, “Helicobacter pylori” and “periodontal”, “Helicobacter pylori” and “scaling root planning” from January 2015 to January 2025, leading to 11 records included in the final analysis. The periodontal treatments evaluated in the studies are scaling and root planing and mouthwashing, in addition to antibiotic protocols for H. pylori eradication (HPE). A quality assessment and risk-of-bias of the studies were also performed. There is evidence that patients with H. pylori infection benefit from NSPT. The limitations of the studies examined are the small samples, the short follow-up, and the few numbers of randomized controlled trials. According to our data, NSPT might be included in HPE guidelines
A Histological and Clinical Evaluation of Long-Term Outcomes of Bovine Bone-Derived Xenografts in Oral Surgery: A Systematic Review
No full textBackground: Bovine bone-derived xenografts are widely used in regenerative dental procedures due to their osteoconductive properties and volumetric stability. However, their long-term behavior and biological integration remain a subject of debate. This systematic review aims to critically assess the histological and clinical outcomes associated with bovine xenografts over extended follow-up periods. Methods: An electronic search was performed in PubMed, Scopus, and Web of Science, including studies published in the English language from 2005 to 2025 for a total of 217 records, which were initially identified from PubMed, Scopus, and Wos. Results: After duplicate removal, following title/abstract screening and full-text evaluation, 11 studies met the inclusion criteria. These studies reported on the use of bovine-derived xenografts in clinical contexts, assessing parameters such as graft integration, histological remodeling, complication incidence (e.g., chronic inflammation or foreign body reactions), and implant success rates over time. Conclusions: The current evidence suggests that bovine-derived xenografts, particularly Bio-Oss®, are associated with favorable long-term outcomes in bone regenerative procedures, demonstrating satisfactory graft integration and implant survival rates. However, variations in study design, follow-up duration, and outcome measures warrant further high-quality, long-term randomized clinical trials to confirm these findings and guide clinical decision-making
