Older adults are vulnerable to poor oral health due to physiological and cognitive changes, multiple medications, and dependence on carers. Despite national guidance, oral care in UK care homes remains inconsistent, and many staff report lacking the personal skills, organisational support, and confidence to deliver consistent oral care despite highlighting their commitment to deliver effective “m…

Abstract Background Cleft lip and palate (CLP) is a malformation traditionally attributed to muscle dysfunction but with deep anatomical origins. While early radiological signs of nasopharyngeal carcinoma often present as an asymmetric obliteration of the Rosenmüller fossa (RF), the impact of congenital CLP-related variations on this clinical detection remains a subject of debate with no definiti…

This study evaluates and compares the mechanical behavior of two collagen membranes in an in vitro model simulating membrane-stabilized horizontal guided bone regeneration (GBR). Megreen ® (bovine pericardium, BP) and Bio-Gide ® (porcine dermis, PD) were tested under wet conditions. Two models were developed: (1) a balloon dilation test to assess the membrane’s capability to accommodate bone graf…

This study aimed to evaluate the effect of four different surface‑treatment protocols—including a novel Optiglaze before post‑curing approach on the surface morphology and color stability of two 3D‑printed permanent resin materials following thermocycling and staining procedures. Two permanent crown materials were fabricated and then divided into four groups, each subjected to one of the followin…

Iron supplements are used as a common remedy to treat iron deficiency for years. Despite widespread research of iron on primary teeth discoloration, their esthetic side effect on permanent teeth remains underexplored. The objective of this study was to assess the effect of different viscosity and pH of two commonly used iron supplements on enamel discoloration of extracted permanent teeth. Sixty …

Alar base widening is a common soft tissue change following Le Fort I osteotomy. Although alar cinch sutures are commonly used to limit this change, their long-term stability remains variable. Nasal sill resection may provide a direct resective option for managing horizontal excess at the alar base; however, its use concomitantly with maxillary orthognathic surgery has not been well described. Th…

Polyaryletherketone (PAEK) polymers, including polyetheretherketone (PEEK) and polyetherketoneketone (PEKK), are increasingly used in prosthodontics because of their favorable mechanical and biological properties. However, their chemically inert and low–surface-energy characteristics result in insufficient bonding to veneering composite resins. Therefore, effective and clinically safe surface tre…

The eighth edition of the American Joint Committee on Cancer (AJCC) staging system incorporated pathologic depth of invasion (pDOI) and pathologic extranodal extension (pENE) for prognostic stratification in oral squamous cell carcinoma (OSCC). However, the extent of stage migration and the consistency of survival discrimination across populations remained controversial. This study aimed to evalu…

Extrusion of anterior teeth is a common manifestation of periodontitis. Orthodontic intrusion is an effective approach for improving occlusion and periodontal health. This study aimed to identify the optimal protocols for maxillary incisor intrusion using clear aligner (CA) in patients with periodontitis. A validated finite element model was established, including the CA, teeth, periodontal ligam…

Abstract Background Implant rehabilitation following post-traumatic dentoalveolar defects can be challenging due to irregular bone loss and insufficient ridge volume that compromise dental implant placement and prosthetic rehabilitation. Aim of the study To evaluate implant rehabilitation following reconstruction of delayed post-traumatic maxillary and mandibular dentoalveolar defects using iliac…

Abstract Background The present study compares the anti-plaque efficacy of two commercially available dentifrices containing natural salivary enzymes in patients undergoing fixed orthodontic therapy. Methodology This prospective, parallel- arm, double-blind, randomized controlled trial included 54 participants undergoing fixed orthodontic therapy who were diagnosed with moderate to severe gingivi…

Patient satisfaction with complete dentures is multifactorial, with aesthetics being a key determinant. The color match between the denture base and the patient’s natural gingiva is a critical aspect of denture aesthetics; however, its specific impact on satisfaction remained unclear. This study aimed to investigate the relationship between the color difference of the denture base from the natura…

External root resorption (ERR) on second molars (M2s) is an undesirable type of pathological damage associated with adjacent impacted third molars (iM3s). Owing to its limited detectability on conventional radiographs, ERR may remain undiagnosed until irreversible damage has occurred. This systematic review aimed to quantitatively evaluate the association between iM3s and ERR on M2s via cone-beam…

This study aimed to evaluate the effects of ceramic composition, resin cement shade, and tooth-shaded background on the optical properties and color differences of high translucent (HT) lithium-based ceramics. A total of 192 specimens were prepared from four CAD/CAM ceramics: advanced lithium disilicate, lithium disilicate, and two zirconia-reinforced lithium silicate ceramics. The relative trans…
