A one-way ANOVA test and an independent sample t-test were used; a p-value of 0.05 was considered the threshold for statistical significance. A total of 312 participants were included; 174 (55.8%) were females. In terms of age distribution, the majority of participants were between 23 and 59 years old (n = 261). Regarding education, predominantly (154, 49.4%) held a bachelor's degree. Regarding socioeconomic factors, 214 participants (68.6%) were framed into the lowest socioeconomic status (SES). The highest prevalence of ETW was observed in the maxillary anterior teeth (90.2%), followed by the mandibular anterior teeth (79.8%). Participants who used hard-bristled toothbrushes (teeth abrasion), consumed acidic products, and belonged to high SES groups had significantly higher erosive tooth wear scores. The overall prevalence of ETW among participants was 69%, with the highest prevalence observed in males, older age groups, and those with higher SES. The findings highlight the significant role of dietary habits, oral hygiene practices, and socioeconomic factors in the development of ETW.","PeriodicalId":19390,"journal":{"name":"Odontology","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147841006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This randomized clinical trial was conducted on 60 patients (17 males and 43 females) with anterior disc displacement with reduction confirmed with magnetic resonance imaging (MRI). The patients were split into two equal groups at random based on the type of treatment that was used. Group 1: arthrocentesis plus PL, Group 2 arthrocentesis plus HA. The pain intensity, clicking sound, maximum inter-incisal opening (MIO) and range of lateral mandibular excursions were measured. All the measured parameters were statistically analyzed. After 6 months, both groups demonstrated a significant improvement in all the parameters that were measured. The PL Group showed a statistically better resolution of clicking compared to HA Group with an Absolute Risk Difference of 33.3% (P < 0.05). The MIO between-group difference was 4.867 mm (P < 0.001), so exceeding the Minimum Clinically Important Difference (MCID). On the other hand, although the PL Group demonstrated statistical superiority in pain scores and range of lateral mandibular excursions (P < 0.05), the clinical magnitude of the between-group difference was modest. PL appears to be a safe and effective adjunctive intra-articular therapy after arthrocentesis for the management of patients with anterior disc displacement with reduction. It provides a clinical advantage over HA in resolving joint clicking and improving MIO. For pain reduction and range of lateral mandibular excursions, the therapeutic benefits of PL and HA are clinically comparable.

Thirty-two systematically and periodontally healthy adults with fixed orthodontic appliances and Plaque Index (PI) > = 25% were enrolled from October 2020 to May 2022, the subjects were equally randomized into test and control group. Primary outcome was the change in the difference in percentage of residual plaque area (RPA) between the two study groups. In the test group, a PDA was applied before professional oral hygiene, whilst the control group received a hygiene session without disclosing. The PDA was then re-applied at the end of the treatment in both groups, and the RPA was assessed via Image-J software analysis of standardized frontal photos and compared between groups. The average RPA in the test group was 3.9% (CI 95% 2.6%; 5.1%), which resulted significantly lower than in the control group, where it reached 12.0% (CI 95% 8.0%-16.0%) (p-value < 0.001). The percentage of area with residual plaque was modelled using a beta-regression model.

In vitro, human dentin samples were exposed at 5 mm or 20 mm to a miniaturized mono channel Helium-jet plasma device for times varying from 15 to 180 s. Contact angle measurements were performed on dentin surfaces, before observations under scanning electron microscopy (SEM). Shear bond strength (SBS) tests were carried out on composite resins until the restoration was separated from the tooth. The results showed that CAP exposure reduced the contact angle as early as 30 s of plasma exposure at 20 mm (21.44 ± 3.99°, p < 0.001) or 15 s at 5 mm (21.04 ± 4.36°, p < 0.001). SEM observations revealed widely opened tubules on CAP-exposed surface. SBS tests revealed a significant influence of CAP application on the adhesion of composite resin to the dentin. The control group showed one of the lowest SBS values (14.48 ± 4.7 MPa) whereas the CAP-treated groups at 5 mm exhibited a progressive increase in bond strength, particularly for the 15 s (20.88 ± 5.10 MPa, p < 0.05) and 30 s conditions (24.49 ± 7.26 MPa, p < 0.001), before a new reduction above 60 s of exposition (19.96 ± 4.97 MPa). Finally, this study highlights the benefits of applying plasma jet at atmospheric pressure on human dentin to enhance the adhesion of restorative composite resins.

Restoring enamel and dentin represents a major challenge in restorative dentistry due to their complex hierarchical architecture and limited intrinsic repair capacity. Conventional restorative materials can restore function but often fail to reproduce the mechanical, aesthetic, and biological properties of natural tissues and are prone to long-term degradation and secondary caries. Recent advances, including cell-free mineralization systems, self-assembling peptides, and nanostructured scaffolds, aim to mimic the structural and chemical environment of developing dental tissues, offering potential for non-invasive, biologically integrated, and durable restorations. This review highlights current progress in elucidating mineralization mechanisms, recent innovations in biomimetic strategies, and evidence from experimental and translational studies on enamel and dentin regeneration. Particular attention is given to emerging materials such as self-assembling peptides, calcium-phosphate based systems, and natural biomolecules including keratin and polyphenols. Finally, future perspectives are outlined, emphasizing integration with tissue engineering bioactive, biomimetic and smart biomaterials to enable functional and long-lasting dental tissue regeneration.","PeriodicalId":19390,"journal":{"name":"Odontology","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147717465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
