Background and Objectives: Medication-related osteonecrosis of the jaw (MRONJ) was first recognized as a disease entity and reported in the literature in 2003. Within a few years, the incidence of MRONJ has increased significantly, to the point where now it can be seen in every dental clinic around the world. Its prevention and management still remain major challenges for dentists and oral and maxillofacial surgeons. Materials and Materials and Methods: This prospective clinical study was conducted at the Oral and Maxillofacial Surgery Clinic in Timisoara for a 6-month period and included a total of 85 patients under chronic antiresorptive and antiangiogenic medication. There were two groups of patients: G1 received PRF growth factors, while the other group, G2, was treated with classical surgical methods. Post-operative wound healing was assessed at 2, 4, and 8 weeks by monitoring the absence of local gingival dehiscence, suprainfection, or loco-regional fistulas, both in cases of dental extractions and sequestrectomies in MRONJ cases. Results: The use of PRF in post-extraction sockets in patients predisposed to developing MRONJ aids in local healing in 96% of cases, compared to cases where it was not used, in which normal healing occurred in only 64.29% of patients; there was a significant difference between the two groups (p = 0.016). In MRONJ confirmed cases, application of PRF after excisional debridement of necrotic bone does not appear to have the same therapeutic value as in post-extractional sockets, with a p-value of 0.299 indicating no statistical significance. Conclusions: PRF use can be considered an effective approach in preventing osteonecrotic complications following dental extractions in patients with antiresorptive treatment. Additional studies are needed to establish its role in MRONJ confirmed cases.

Background and Objectives: The extraction of mandibular third molars poses challenges due to their proximity to the mandibular canal and risk of inferior alveolar nerve (IAN) injury. Accurate preoperative evaluation is essential to minimize complications. This study assessed the three-dimensional positional relationship between the mandibular canal and lower third molars using cone-beam computed tomography (CBCT), aiming to identify anatomical positions associated with increased surgical risk. Materials and Methods: This retrospective study analyzed 253 CBCT scans of fully developed lower third molars. The mandibular canal position was classified as apical (Class I), buccal (Class II), lingual (Class III), or interradicular (Class IV). Contact was categorized as no contact, contact with a complete or defective white line, or canal penetration. In no-contact cases, the apex–canal distance was measured. Statistical analysis included descriptive and contingency analyses using the Chi-Square Likelihood Ratio test. Results: Class I was most common (70.8%) and presented the lowest risk, while Classes III and IV showed significantly higher frequencies of canal contact or penetration. Class II exhibited shorter distances even in no-contact cases, suggesting residual risk. Statistically significant associations were found between canal position and both contact type (p < 0.001) and apex–canal distance (p = 0.046). Conclusions: CBCT offers valuable insight into the anatomical relationship between third molars and the mandibular canal. High-risk positions—particularly lingual and interradicular—require careful assessment. Even in the absence of contact, close proximity may pose a risk and should inform surgical planning.

Background/Objectives: The most common form of supernumerary teeth is represented by the mesiodens. Very often, they are impacted, usually palatially, but can be found buccally or between the roots of the permanent central incisors. Their position can be normal, inclined, or inverted. In the possible case where the impacted mesiodens crown is oriented upwards towards the nasal cavity, they are called inverted mesiodens. The inverted mesiodens are mainly asymptomatic, and the main diagnostic methods are radiological, especially CBCT. Methods: This paper presents the intraoral approach through the nasal floor as a very reliable method for the surgical removal of inverted mesiodens. We report a protocol, including the diagnosis process, criteria for choosing this surgical approach, and description of the surgical procedure. Preoperative CBCT is mandatory for diagnosis and choice of the surgical approach. This is chosen based on measurements on the cross-sectional view of the CBCT investigation and is in compliance with our criteria related to the appropriate surgical approach. Results: Using this approach, the mesiodens were extracted without intraoperative or postoperative complications or accidents, and operating times were relatively short. Conclusions: The intraoral approach through the nasal floor for surgical removal of inverted mesiodens satisfies all the conditions to be a predictable, safe, and time-efficient technique. It has its limitations, mainly regarding the surgical skills of the operating team. The cone–beam computed tomography (CBCT) has a fundamental role in the diagnosis and treatment of included mesiodens.

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.
