Interdisciplinary management of orofacial lesions in early childhood: paediatric alert system at University of Verona.

Orofacial trauma (OFT) occurs frequently in children and requires thorough evaluation not only by paediatric dentists but also by all specialists involved in emergency services, particularly in cases involving children under 3 years of age, given their inability to directly participate in clinical-anamnestic evaluations. Addressing early childhood orofacial trauma resulting from maltreatment, this study explores the key role played by various healthcare professionals, including paediatric dentists, general dentists, maxillofacial surgeons, dental hygienists, and paediatricians, in the optimal management of these cases. In the event of trauma due to suspected or confirmed mistreatment, it is essential that all healthcare workers involved have precise knowledge of the appropriate course of action from both a clinical and legal point of view, guaranteeing maximum protection for the young patient.

The aim of this retrospective study was to investigate this hypothesis in locking-taper implants with a mid-term follow-up of 5 years. Overall, 155 implants (32, 100, and 23 of, respectively, 5.

Bilateral reconstruction of the mandibular body with symphyseal preservation using a single fibula free flap: operative technique.

Background: Mandibular osteonecrosis may occur in 5% of the patients who undergo radiotherapy for the treatment of head and neck malignancies. Resection and microvascular reconstruction is the treatment of choice in complicated osteoradionecrosis, however multifocal presentation may complicate the management of the disease given the poor quality and limited availability of adequate recipient vessels.

Operative Technique: A 74-year-old man affected by multifocal severe osteoradionecrosis of the mandible underwent bilateral resection of the mandibular bodies while preserving the symphysis.

Short and ultra-short (<6-mm) locking-taper implants supporting single crowns in posterior areas (part II): A 5-year retrospective study on periodontally healthy patients and patients with a history of periodontitis.

Background: Short and ultra-short implants implants supporting single crowns seem to demonstrate high percentages of survival and stable marginal bone levels at a mid-term follow-up. Nevertheless, insurgence of peri-implant complications still represents a critical issue, especially for patients with history of periodontitis.

Purpose: The aim of this retrospective study was to evaluate implant survival, marginal bone loss and peri-implant complications in 333 short and ultra-short implants, placed in periodontally healthy patients and patients with a history of periodontitis.

Expression of Beta-Catenin, Cadherins and P-Runx2 in Fibro-Osseous Lesions of the Jaw: Tissue Microarray Study.

Fibrous dysplasia (FD) and hyperparathyroidism-jaw tumor syndrome (HPT-JT) are well-characterized benign bone fibro-osseous lesions. The intracellular mechanism leading to excessive deposition of fibrous tissue and alteration of differentiation processes leading to osteomalacia have not yet been fully clarified. Tissue Microarray (TMA)-based immunohistochemical expression of β-catenin, CK-AE1/AE3, Ki-67, cadherins and P-Runx2 were analyzed in archival samples from nine patients affected by FD and HPT-JT and in seven controls, with the aim of elucidating the contribution of these molecules (β-catenin, cadherins and P-Runx2) in the osteoblast differentiation pathway.

Survival rates of ultra-short (<6 mm) compared with short locking-taper implants supporting single crowns in posterior areas: A 5-year retrospective study.
