(1) Background: The general hypothesis that HNC patients show compromised oral health (OH) is generally accepted, but it is not evidence-based. The objective of this baseline report of a prospective observational study was to describe the oral health of a cohort of patients with HNC at the time of dental evaluation prior to radiotherapy (RT). (2) Materials and Methods: Two hundred and thirteen patients affected by HNC who had received an indication for RT were examined with the support of orthopantomography (OPT). The DMFt of all included subjects, their periodontal status and the grade of mouth opening were recorded. (3) Results: A total of 195 patients were ultimately included: 146/195 patients (74.9%) showed poor OH (defined as having a DMFt score ≥ 13 and severe periodontitis). The following clinical characteristics were correlated with poor oral health in the univariate analysis: tumor site, smoking habit and age of the patients (in decades); χ2 test, p < 0.05. (4) Conclusions: This study confirms that the OH of HNC patients is often compromised even before the beginning of cancer treatment and, consequently, highlights how important it is to promptly schedule a dental evaluation at the moment of diagnosis of the cancer.

Background: Saprochaete clavata infection is an emerging issue in immunosuppressed patients, causing fulminant fungaemia. The purpose of this systematic review of cases is to retrieve all cases of S. clavata infection and describe oral lesions as the first manifestation of S. clavata infection. Methods: We report the first case of intraoral S. clavata infection in Acute Myeloid Leukemia (AML) affected subject, presenting as multiple grayish rapidly growing ulcerated swellings, and provide a review of all published cases of infection caused by S. clavata, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, conducted by searching SCOPUS, Medline, and CENTRAL databases. Only articles in English were considered. Individual patient data were analyzed to identify risk factors for S. clavata infection. Results: Seventeen of 68 retrieved articles were included in the review reporting data on 96 patients (mean age 51.8 years, 57 males and 38 females). Most cases were disseminated (86) with a 60.2% mortality rate. Ninety-five were hematological patients, with AML being the most common (57 cases). Conclusions:S. clavata infection in immunosuppressed patients has a poor prognosis: middle-age patients, male gender and Acute Myeloid Leukemia should be considered risk factors. In immunosuppressed patients, the clinical presentation can be particularly unusual, imposing difficult differential diagnosis, as in the reported case.

(1) Background: Condylar fracture healing pattern classification in children and adolescents is primarily based on the radiological assessment of condylar morphology; however, recent studies showed the presence of a poor correlation between post-treatment radiological findings and clinical temporomandibular joint (TMJ) dysfunction. The present case series aimed to correlate the condylar morphology, shape, and trabecular bone density with the skeletal asymmetry and the clinical recovery of two growing patients with unilateral condylar fractures undergoing orthopedic treatment with the Balters Bionator appliance. (2) Methods: Pre- and post-treatment (12 months) cone-beam computed tomography (CBCT) scans of two growing patients with unilateral condylar fracture were retrieved; both patients were treated with the Balters Bionator appliance for one year. Morphological evaluation of the condylar healing pattern was carried out on CBCT reconstructions of the mandible. Condylar remodeling and skeletal asymmetry were assessed through linear measurements performed on pre- and post-treatment CBCT scans; then, fractal analysis (FA) was employed to assess the condylar trabecular bone density on orthopantomographies (OPTs). Clinical and TMJ functional evaluation were retrieved from patients’ records from before and at the end of the treatment (12 months). (3) Results: Conservative treatment of condylar fractures in growing patients led to an increased bone density of the condylar heads, regardless of the post-treatment size and morphology of the injured condyles. Patient one presented an unchanged condylar morphology on the affected side, while patient two’s condyle was slightly spherical. The qualitative results were confirmed by quantitative measurements on CBCTs. The radiological healing patterns were associated with slightly different functional outcomes. Both patients also exhibited an improvement in skeletal asymmetry and TMJ function. (4) Conclusions: According to the findings in the present study, the condylar remodeling and bone apposition after conservative treatment of condylar fractures in growing patients can exhibit different radiological and functional outcomes. Indeed, an unchanged morphology of the condylar head is more likely to determine a physiological TMJ recovery.

Objectives: To evaluate (a) changes in caries experience, (b) changes in periodontal status, and (c) the need for dental extractions in a cohort of patients treated with radiotherapy (RT) and chemoradiotherapy (RTCT) for head and neck cancer (HNC). Methods: This prospective cohort study was approved by the local Ethics Committee (Ref. 22858/18) and registered at ClinicalTrials.gov (ID: NCT04009161). The study population consisted of patients with HNC who, prior to RT, underwent a dental examination followed by the elimination of oral foci of infection and were then enrolled in a follow-up program. The primary outcome was oral health worsening, defined as the onset of severe periodontitis and/or a DMFt score ≥ 13. Oral cavity RT dose was obtained contouring the ‘buccal mucosa’ organ at risk (OAR). Results: In total, 113 patients were included (median follow-up: 44.77 months). The sample mainly included oral, oropharyngeal, nasopharyngeal and laryngeal cancers (89/113, 78.8%). Salivary glands, hypopharynx and other sites accounted for a minority of the cases (24/113, 21.2%). Seventeen patients (34.7%) experienced worsening of oral health status over time, which was associated with smoking (OR = 4.7, 95% CI: 1.27–17.37; p = 0.02). The DMFt index increased (difference: 4.08; 95% CI: 1.60–6.56; p = 0.001), and this increase was associated with smoking (β = 2.05, 95% CI: 0.27–3.83; p = 0.02). Although worsening of periodontitis stage was not statistically significant (p = 0.35), localized deterioration was observed, with an increase in sites with PPD ≥ 5 mm (p = 0.02). Forty-nine patients (43.4%) experienced tooth loss. Mean tooth loss was 2.12 teeth per patient (p = 0.05), primarily due to caries (48.5%) and periodontitis (48.1%). Independent risk factors for tooth loss were age (p = 0.025) and an RT dose > 60 Gy to the ‘buccal mucosa’ OAR (p = 0.023). Conclusions: Patients treated with RT experienced significant deterioration in dental and periodontal health, and oral cavity dosimetric parameters might be associated with tooth loss, although this association requires confirmation in further studies.

Background/Objectives: This study aimed to describe and quantify facial soft tissue changes in two patients who underwent radiotherapy (RT) for head and neck cancers, using three-dimensional (3D) stereophotogrammetry and surface deviation analysis. The aims were (i) to assess the progression of morphological alterations over time (ii) and to evaluate the clinical potential of 3D surface mapping in documenting RT-related aesthetic changes. Methods: Two patients with head and neck cancer undergoing RT were analyzed using three-dimensional stereophotogrammetry (3dMD Trio-system, Atlanta, GA, USA) at three timepoints: before RT (T0), 45 days after the start of RT (T1), and 6 months after the start of RT (T2). Facial 3D scans were processed using Geomagic Control 2014 software (v.3D Systems, Morrisville, NC, USA) to perform standardized alignments and calculate volumetric deviations, create colorimetric deviation maps, and conduct Root Mean Square (RMS) analysis. Results: Between T0 and T1, both patients showed soft tissue volume reduction, primarily in the mandibular and submental regions, likely reflecting acute treatment effects and weight loss. Between T0 and T2, an increase in soft tissue volume was observed, especially in the lower face and neck, consistent with late radiation effects such as lymphedema and post-treatment weight gain. RMS values ranged from 5.53 mm to 6.87 mm across patients and time points, indicating measurable morphological changes. The upper third of the face remained stable and served as a reliable reference region for alignment. Conclusions: RT may be associated with significant, region-specific changes in facial and cervical soft tissues in HNC patients, but these preliminary observations must always be correlated with weight loss and confirmed by further studies. 3D stereophotogrammetry is a reliable, non-invasive method for detecting and quantifying these alterations over time. This technique can offer valuable insights for clinical monitoring and could promote better patient counseling and potentially mitigate the psychological burden associated with facial changes.

Pycnodysostosis (PDS) is an autosomal recessive form of osteosclerotic skeletal dysplasia characterized by craniofacial anomalies, a high-arched palate, and a narrowed pharyngeal space due to mandibular and maxillary deficiencies. These structural anomalies in the upper airway predispose PDS patients to obstructive sleep apnea (OSA). OSA can be managed in PDS patients using either a conservative (non-surgical and multidisciplinary) approach or surgical interventions. Given the craniofacial anomalies associated with PDS, orthodontic treatment aims to address the maxillary transverse deficit and retrognathia. Currently, there is no evidence regarding the impact of orthodontic therapy on OSA levels among PDS patients. This study reports the long-term morphological and functional changes in the upper airway of a PDS patient following adenotonsillectomy and uvulopalatoplasty at an early age (3.6 years) and orthodontic camouflage in late mixed dentition (10 years). Polysomnographies (PSGs), nuclear magnetic resonance (NMR), and lateral cephalograms taken before and after ENT surgery and orthodontic treatment were analyzed. Lateral X-rays were evaluated for changes in the posterior airway space (PAS), while polysomnographies provided the apnea–hypopnea index (AHI). The NMR scans were segmented to measure the perimeter and radius of the upper airway. The findings of this study indicate that improvements following uvulopalatoplasty (UPP) were partial and temporary. Nonetheless, orthodontic therapy and the use of elastics did not appear to influence the PAS or AHI. Future studies with larger cohorts are needed to evaluate the long-term effectiveness of the UPP procedure. This study was conducted in accordance with the CARE guidelines.
