Background/Objectives: Perforation of the maxillary sinus floor by dental implants is a complication that can occur during treatment in posterior sectors; however, its clinical and radiological consequences remain controversial. Therefore, this study aimed to use the diagnostic value of CBCT to determine the possible association between sinus floor-perforating implants and their clinical and/or radiological impact. Methods: A retrospective observational study was conducted on CBCT scans from 21 patients with implants protruding into the maxillary sinus. Morphometric analysis was performed to assess sinus membrane thickening (SMT) patterns, height, surface area and density and the presence of sinonasal symptoms. Statistical analysis was used to explore potential associations between SMT and variables such as implant protrusion length, number of perforating implants, age and gender. Results: SMT was observed in all patients, with a mean area of 11.1 ± 6.4 mm² in panoramic sections. Most cases (85.7%) exhibited a circumferential SMT pattern. No statistically significant correlation was found between SMT and implant protrusion length, age or sex. Additionally, none of the patients reported sinonasal symptoms, and no clinical signs of sinusitis were detected during follow-up. Conclusions: Although sinus floor-perforating implants commonly induce SMT detectable on CBCT, this thickening appears largely asymptomatic and may not compromise patient well-being in the short term. Nevertheless, clinicians should monitor these cases radiographically to detect possible long-term complications.

Background: Depression is a prevalent mental health condition among older adults and may be linked to multiple systemic and functional factors. Emerging evidence suggests a bidirectional relationship between depressive symptoms and poor oral health, but data from European populations remain scarce. Methods: A cross-sectional study was conducted in 181 community-dwelling adults aged over 66 years in Madrid, Spain. Depressive symptoms were assessed using the Geriatric Depression Scale (GDS-15), and functional dependence using the Barthel Index. Oral examinations included the number of caries, root remnants, and gingivitis. Additional variables included the Body Mass Index (BMI), smoking and alcohol consumption, and medication use. Data were analysed using descriptive and non-parametric statistics. Results: Overall, 49.2% of participants exhibited depressive symptoms (34.8% moderate, 14.4% severe). Old age and excess weight were significantly associated with depression (p < 0.05). Depressed participants showed higher functional dependence scores on the Barthel Index (p < 0.001). Oral health indicators, including higher number of caries, root remnants, and gingivitis, were significantly worse among those with depression (p < 0.005). Oral hygiene practices such as toothbrushing were slightly more frequent in the non-depressed group, while oral irrigator use was low across all groups. Conclusions: Depressive symptoms in older Spanish adults were associated with poorer oral health, greater functional dependence, and certain clinical factors such as BMI and antidepressant use. These findings highlight the importance of integrated, multidisciplinary approaches to promote both mental and oral health in ageing populations. Longitudinal studies are warranted to clarify the causal pathways underlying these associations.

Background: The styloid process exhibits considerable anatomical variability, and its elongation is frequently identified as an incidental finding on panoramic radiographs. However, limited evidence exists regarding its prevalence and possible association with craniofacial skeletal characteristics in adult orthodontic patients. Therefore, the aim of this study was to evaluate the prevalence, morphological characteristics, mineralisation patterns, and possible association of styloid process elongation with skeletal class and facial pattern in an adult orthodontic population. Methods: A retrospective cross-sectional study was conducted on 340 adult orthodontic patients (130 males and 210 females; mean age: 51.55 ± 6.62 years). Panoramic radiographs were used to assess styloid process elongation, defined as ≥30 mm, as well as its morphology and mineralisation patterns according to the Langlais classification. Lateral cephalograms were analysed to determine skeletal class and facial pattern. Statistical analysis included descriptive and inferential methods, with significance set at p < 0.05. Results: Styloid process elongation was identified in 47.65% of patients. Elongated processes showed significantly greater length and side asymmetry (p = 0.001). The most frequent morphology was normal (Type IV), while complete mineralisation (Type D) predominated. No significant associations were found between elongation and age or sex. Furthermore, no statistically significant relationship was observed between elongation and skeletal class (p = 0.479) or facial pattern (p = 0.531). Only a small proportion of patients reported symptoms according to the available clinical records, with no clear association with styloid process elongation. Conclusions: Styloid process elongation is a common incidental finding in adult orthodontic patients and does not appear to be associated with skeletal class or facial pattern. Its recognition on panoramic radiographs may improve the differential diagnosis of orofacial and cervical symptoms.

Paradental cysts are inflammatory lesions that typically occur associated with the mandibular third molar, posing a challenge in the differential diagnosis with other odontogenic cysts. This paper describes the diagnostic and therapeutic management of a paradental cyst that was initially considered a dentigerous cyst based on its pericoronal location and radiological appearance as a well-defined unilocular radiolucency associated with an impacted tooth. A 64-year-old male patient presented with pain in the right mandibular region. Panoramic radiography and cone-beam computed tomography revealed a well-defined unilocular lesion associated with an impacted mandibular third molar, extending towards the mandibular second molar. Surgical treatment included complete enucleation of the lesion and extraction of both teeth. Histopathological analysis showed a non-keratinized stratified epithelial lining with chronic inflammatory cell infiltrate; together with the clinical and radiological findings, this allowed the definitive diagnosis of a paradental cyst. The postoperative course was uneventful, and a follow-up radiograph obtained at nine months showed early signs of ossification of the residual cavity.
