The use of natural products as alternatives to traditional pharmacological treatments in orthodontics is gaining interest due to their anti-inflammatory, antibacterial, and antioxidant properties. This systematic review synthesizes evidence from clinical trials to evaluate the efficacy of natural products in reducing inflammation and bacterial presence in orthodontic and orthognathic treatment settings. The database search was conducted across PubMed, Scopus, and Embase up to January 2024. The review focused on randomized controlled trials only. The selected studies centered on the anti-inflammatory, antibacterial, and antioxidant effects of natural products, adhering to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines for data extraction. Nine studies, totaling 358 participants, were included. Significant findings demonstrated a reduction in gingival inflammation by over 40% with the use of Aloe vera compared to chlorhexidine. Another study noted a decrease in bleeding on probing by 13.6 points in the treatment group over placebo. Additionally, honey showed a rapid modulation of plaque pH and significantly reduced bacterial counts of Streptococcus mutans. Furthermore, the use of resveratrol emulgel was linked to substantial improvements in gingival health, with a reduction in the gingival index and probing pocket depth. The results indicate that natural products can significantly enhance orthodontic treatment outcomes by reducing inflammation and bacterial levels. These products offer effective alternatives to traditional treatments and show potential for integration into routine orthodontic care protocols. Further research is encouraged to standardize application methods and dosages to maximize clinical benefits and patient satisfaction.

Background: Dentofacial deformities (DFDs) comprise heterogeneous sagittal, vertical, transverse, and asymmetry components, yet clinical severity is often summarized using isolated measurements. Objectives: To operationalize a reproducible composite DFD severity score and evaluate its cross-sectional associations with quality of life, function, airway-related screening indicators, and psychosocial burden. Methods: In this single-center cross-sectional study, consecutive adults assessed in an orthognathic surgery pathway underwent a prespecified 0–100 severity scoring framework integrating sagittal discrepancy (|Wits| and |ANB deviation|), vertical pattern (SN-MP angle), and asymmetry/transverse variables (chin deviation, asymmetry index, transverse discrepancy, and absolute overjet). Outcomes included the Oral Health Impact Profile-14 (OHIP-14), Orthognathic Quality of Life Questionnaire (OQLQ), FACE-Q facial appearance satisfaction scale, PHQ-9, GAD-7, STOP-Bang, functional testing, and CBCT-derived upper-airway metrics. Results: Severe DFDs had higher composite severity (62.9 ± 12.8 vs. 25.3 ± 10.9), larger sagittal discrepancy (|Wits| 6.3 ± 2.8 vs. 3.1 ± 1.8), and higher SN-MP angles (39.8 ± 7.4 vs. 34.7 ± 7.2) (all p < 0.001). Severe DFDs also had worse OQLQ (36.2 ± 6.2 vs. 24.1 ± 7.2), OHIP-14 (18.3 ± 4.2 vs. 12.4 ± 4.1), FACE-Q satisfaction (45.7 ± 10.3 vs. 67.6 ± 9.6), masticatory performance (59.4 ± 8.5 vs. 75.1 ± 7.5), and smaller airway area (126.7 ± 29.6 vs. 161.4 ± 27.7) (all p < 0.001). In multivariable logistic regression, |Wits|, SN-MP angle, asymmetry index, and lower airway area independently predicted severe status; PHQ-9 was associated with severity in unadjusted analyses but did not retain independent significance after multivariable adjustment. Model discrimination was high (AUC 0.91). Conclusions: This multidimensional severity framework captures clinically meaningful cross-sectional differences across morphologic, functional, airway-related, and psychosocial domains. Its interpretability remained stable in sensitivity analyses, but external and longitudinal validation is still required before broader implementation.

Background: Large periapical cyst-like lesions pose challenges for nonsurgical management. This study evaluated the clinical and radiological outcomes of conventional endodontic therapy alone versus endodontic therapy with decompression in treating such lesions. Methods: Ten patients with CBCT-confirmed periapical lesions >5 mm were randomly assigned to two groups. Group 1 received standard root canal treatment with calcium hydroxide; Group 2 received the same protocol plus decompression. Lesion dimensions were measured in three planes using CBCT at baseline, 12 months, and 24 months. Results: Both groups showed significant lesion size reduction over time. At 12 months, Group 2 had a significantly greater mean reduction (8.49 ± 5.09 mm) compared to Group 1 (4.36 ± 1.46 mm) (p = 0.008). At 24 months, both groups had comparable outcomes (Group 1: 1.12 ± 0.98 mm; Group 2: 2.41 ± 5.15 mm; p = 0.356), with most lesions nearly or fully resolved. Histopathology confirmed radicular cysts in decompressed cases. Conclusions: Conservative endodontic therapy is effective for large periapical lesions. Adjunctive decompression accelerates early healing, particularly in extensive cases, potentially reducing the need for surgical intervention. CBCT is valuable for monitoring healing.

Background and Objectives: Odontogenic infections (OIs) can lead to severe complications if not promptly diagnosed and treated. The Quick Sequential Organ Failure Assessment (qSOFA), derived Neutrophil-to-Lymphocyte Ratio (dNLR); Modified Early Warning Score (MEWS); and Predisposition, Infection, Response, and Organ Dysfunction (PIRO) scores are clinical tools used to predict the severity and outcomes in various infections. This study aims to evaluate the efficacy of these scores in predicting the severity of OIs in adult patients. Methods: A retrospective cohort study was conducted on 120 patients hospitalized for OIs, divided into two groups based on infection severity, using the Symptom Severity (SS) scale. The qSOFA, dNLR, MEWS, and PIRO scores were calculated upon admission. Statistical analyses were performed to assess the predictive value of these scores for severe OIs. Results: Patients with severe OIs (Group B) had significantly higher qSOFA, dNLR, MEWS, and PIRO scores compared to those with lower severity (Group A). The median qSOFA score was 2.00 in Group B versus 0.85 in Group A. No significant difference was observed between young patients and adults in terms of severity. ROC curve analysis showed that the PIRO score had the highest predictive value for severe OI (AUC = 0.912), followed by MEWS (AUC = 0.878), qSOFA (AUC = 0.845), and dNLR (AUC = 0.812). Multivariate logistic regression indicated that the PIRO score was an independent predictor of severe OI (OR = 8.45, 95% CI: 4.12–12.78). Conclusions: The qSOFA, dNLR, MEWS, and PIRO scores are valuable tools for predicting the severity of OIs. Among them, the PIRO score demonstrated the highest predictive accuracy and may be incorporated into clinical practice for early identification of high-risk patients.

Background and Objectives: Conventional dental adhesives doped with magnetic nanoparticles (MNPs) hold the promise of preventing microleakages. However, esthetic concerns have motivated the quest for coatings capable of masking the dark color of MNPs. This study aims to quantify regional chromatic differences between teeth restored using dental adhesives with different MNP content. Materials and Methods: We prepared cavities in 42 artificial molars and 9 extracted teeth and divided them into 6 groups: Group 0 (G0), G1, and G2, comprising 14 artificial teeth each and G0e, G1e, and G2e, comprising 3 extracted teeth each. In G0 and G0e, we applied the commercial adhesive, in G1 and G1e we applied the adhesive loaded with MNPs with dual coating (SiO2 followed by Ca(OH)2), whereas in G2 and G2e we applied the adhesive doped with uncoated MNPs. For the statistical analysis of color differences, we employed Bland–Altman plots and the one-sample t-test. Results: G1 was similar to G0 in terms of color coordinate distribution, whereas G2 was different. Compared to G0, dental fillings from G1 had mean differences of (−0.56, 0.18, −0.07) in the CIELAB color coordinates (L*, a*, b*), respectively, whereas the mean differences between G2 and G0 were (−15.6, −3.5, −15.7). The CIEDE2000 color differences were 1.5 [1.3, 1.6] between G1 and G0 (mean [95% confidence interval]) and 17.0 [16.0, 18.0] between G2 and G0. Nevertheless, 24.4% of the point pairs compared exceeded the acceptability limit for color difference (1.8). Conclusions: Although the silica and calcium hydroxide coating is highly effective in alleviating the esthetic impact of MNP-laden dental adhesives, further research is warranted to reduce between-specimen variability.
