Radiation treatment plays a mainstream role in the management of head and neck squamous cell carcinomas (HNSCCs). Adverse effects from radiation therapy include osteoradionecrosis of the jaw, and rarely, pathologic fracture. Immune checkpoint inhibitors (ICI) such as pembrolizumab are of growing relevance to the management of metastatic and recurrent HNSCCs. Adverse impacts on bone secondary to medications such as pembrolizumab and nivolumab have been sporadically documented in the literature. The objective of this manuscript is to raise awareness of possible increase in risk for adverse jaw outcomes in patients with HNSCCs exposed to both radiation treatment to the jaws and ICI therapy...

OBJECTIVE: Currently, there is no established treatment protocol to treat interdental papillary loss. This research aimed to evaluate the outcomes of interdental papillary reconstruction using minimally invasive surgery, with injectable hyaluronic acid gel. METHOD AND MATERIALS: Seventeen patients were included, each with five sites of class 1 papillary recession (40 sites in the maxilla and 45 sites in the mandible). Subperiosteal tunneling was performed through a horizontal incision made apical to the base of the papilla without penetrating it...

OBJECTIVE: The goal was to identify the lifestyle risk factors associated with benign and potentially malignant oral disorders. METHOD AND MATERIALS: The study enrolled first-time patients from the Oral Pathology Section, volunteers from Oviedo, and first-time patients from University of Oviedo dental clinic. Patients underwent a survey that included sociodemographic information, lifestyle habits, and medical history. Then, a comprehensive examination of the oral mucosa was conducted...

OBJECTIVES: This case series aimed to assess the efficacy of a novel horizontal ridge augmentation modality using histology. Combinations of "sticky bone" and tenting screws without autologous bone were used as augmentative materials. METHODS AND MATERIALS: Five individuals presenting healed, atrophic, partially edentulous sites that required horizontal bone augmentation before implant placement were enrolled. Patients underwent the same augmentation type and five months of postoperative reentry procedures...

OBJECTIVE: To compare effect of planning interventions on self-reported changes in parents supervised oral health related behaviours (OHRBs) and associated clinical oral health parameters for 'primary school age' children. METHODS: 110 parent-child pairs (children aged 3-8 years) were randomly assigned to either of the two groups. In 'Action planning' group (AP), parent participants of the pair were asked to make 'action plan' within "how, when, where" format for their child OHRBs...

BACKGROUND: Glossopharyngeal neuralgia due to vertebrobasilar dolichoectasia is a rare form of neuropathic pain and presents with diagnostic and therapeutic challenges. CLINICAL PRESENTATION: A 67-year-old man presented with severe burning pain in the left oral cavity, with no explanatory findings during dental and ENT evaluations. TMJ examination revealed tenderness, and panoramic radiographs showed a non-contributory periapical radiolucency. MRI/MRA revealed abnormally tortuous vertebral arteries compressing the glossopharyngeal nerves and the brainstem...

OBJECTIVES: Autoimmune activation by COVID-19 infection/vaccination has been postulated to be responsible for initiating or reactivating multiple types of oral mucosal immune disorders. These include oral lichen planus (OLP); oral pemphigoid, either bullous pemphigoid (BP) or mucous membrane pemphigoid (MMP) with oral involvement; pemphigus vulgaris (PV) with oral involvement; or Sjögren's disease. In addition, chronic conditions such as oral burning, xerostomia or changes in taste and/or smell have also been linked to COVID-19 infection/vaccination...

OBJECTIVES: To assess the effect of Community Water Fluoridation (CWF) in the prevalence of dental caries and dental fluorosis in 12-year-old children living in Israel. Considering that CWF is important in the prevention of dental caries. Between 2002 and 2014, the water in communities of at least 5,000 individuals was fluoridated. In 2014, CWF in Israel stopped. METHOD AND MATERIALS: Data on 12-year-old children from all areas in Israel from the national cross-sectional epidemiological survey conducted in 2011 to 2012 were stratified by city water fluoridation and by city and school socioeconomic status...

BACKGROUND: This retrospective study analyzed radiographic bone levels of 10871 dental implants in a cohort of 4247 patients over a 22-year period. The objectives of the study were to assess and explore risk factors associate with the radiographic bone level of dental implants. METHODS: A longitudinal observational cohort study based on data collected from 1995 to 2019 was conducted on implants placed by a single periodontist. Inclusion criteria included both partially and fully edentulous sites...

OBJECTIVE: This clinical case outlines a comprehensive digital workflow for a minimally invasive multidisciplinary treatment. The process utilizes one open-source software for digital wax-up and one low-cost software to address esthetic concerns related to teeth misalignment. The patient's function is stabilized with a digitally made occlusal splint. CLINICAL CONSIDERATIONS: The case report illustrated the achievement of immediate and highly esthetic restoration, ensuring proper teeth alignment through a complete digital workflow...

The evidence base for the use of space maintainers (SMs) is relatively sparce despite being used for decades after the premature loss of primary molars. Thus, this study aims to increase the dental evidence base via investigating retrospectively the success rates of prefabricated fixed and removable space maintainers inserted from 2019 to 2021 and followed up until 02/2023 at a specialized university clinic and to identify reasons of any reported minor and major failure. Authors hypothesized that there is no significant difference in failure rates between fixed and removable SMs inserted after the premature loss of a single primary molar per quadrant...

OBJECTIVES: To evaluate polymerization efficiency of different bulk-fill resin-based composites (BFRBCs) cured by monowave and polywave light curing units (LCUs), by assessment the degree of conversion (DC) and Vickers microhardness (VMH) at different depths. METHOD AND MATERIALS: Two commercially available BFRBCs were used; Filtek One Bulk Fill Restorative (3M ESPE) (FOBF) and Tetric N-Ceram Bulk Fill (Ivoclar Vivadent) (TNBF). LCUs utilized were two light-emitting diodes (LEDs) LCUs; a monowave LED LCU (BlueLEX LD-105, Monitex) and a polywave LED LCU (Twin Wave GT-2000, Monitex)...

BACKGROUND: This study aimed to evaluate the effectiveness of biomaterials in bone healing of critical bone defects created by piezoelectric surgery in rats calvaria. MATERIAL AND METHODS: Histomorphological analysis was performed to assess bone regeneration and tissue response. Fifty animals were randomized into 5 groups with one of the following treatments: Control group (CO, n=10), spontaneous blood clot formation with no bone fill; BO group (Bio-Oss®, n=10), defects were filled with bovine medullary bone substitute; BF group (Bonefill®, n=10), defects were filled with bovine cortical bone substitute; hydroxyapatite group (HA, n=10), defects were filled with HA; calcium sulfate group (CS , n=10), defects were filled with CS...

Orofacial pain is a worldwide pain problem with many patients unable to find appropriate diagnosis and treatment. Orofacial pain includes pain arising from the odontogenic and nonodontogenic structures in the head and neck region. Dental clinicians need to have a thorough knowledge and skill to diagnose, manage and treat patients with odontogenic pain or refer patients for treatment of non-odontogenic pain to specialists such as Orofacial pain specialist, neurologist, otolaryngologist, rheumatologist, etc. More often, dentists diagnose patients with a temporomandibular disorder and when treatment is ineffective, term it "atypical facial pain"...

OBJECTIVES: Sedation is commonly utilized for individuals otherwise unable to receive dental treatment; such as those with disabilities, medically complex conditions, and dentophobics. We aimed to characterize the profiles of patients receiving various types of sedation and assess the corresponding success rates. MATERIALS AND METHODS: A 5 years records-based retrospective study. Data regarding the indication for sedation, medical history, sedation type and treatments performed were recorded...
