A Review on Image Processing and Fractal Analysis in Oral Potentially Malignant Disorders

Oral Diseases, EarlyView.
ABSTRACT Aim The clinical evaluation of patients with oral potentially malignant disorders is primarily based on physical examination and observable clinical features. Clinical photographs play a key role in patient monitoring and help identify signs that may indicate malignant transformation.

Immunomodulatory effects of photodynamic therapy for skin cancer: Potential strategies to improve treatment efficacy and tolerability

Photochemistry and Photobiology, EarlyView.
Photodynamic therapy (PDT) is a nonscarring treatment modality that is widely used for skin cancers and early squamous precursor lesions. PDT was previously thought to work primarily by killing cancer cells directly (via apoptosis or necrosis). However, more recent work indicates that a significant mechanism for PDT is the stimulation of anti‐cancer ...

Role of antimicrobial photodynamic therapy (aPDT) and systemic resveratrol on immediate implant placement in type 2 diabetic rats

Photochemistry and Photobiology, EarlyView.
This study evaluated the combined effects of antimicrobial photodynamic therapy (aPDT) and systemic resveratrol on bone repair around immediately placed implants in type 2 diabetic rats. Resveratrol improved glycemic control and body weight, while aPDT increased implant stability and bone mineralization.

Inhibition of P‐glycoprotein using photoimmunotherapy in peritoneal metastasis mouse model

Photochemistry and Photobiology, EarlyView.
Photoimmunotherapy (PIT) using photoimmunoconjugates (PICs) can inhibit the function of the ATP‐binding cassette (ABC) transporter P‐glycoprotein (P‐gp) in a mouse model of peritoneal carcinomatosis. Sterile‐filtered PIC was administered in vivo via intraperitoneal (IP) injection 20 days after IP tumor cell implantation of P‐gp‐overexpressing NCI/ADR ...

Hydroxyaldehyde and formyl photoproducts of protoporphyrin IX formed under photodynamic diagnosis and therapy irradiation conditions

Photochemistry and Photobiology, EarlyView.
Photoproducts of the photosensitizer protoporphyrin IX (PpIX) may have diagnostic and therapeutic relevance in photodynamic diagnosis (PDD) and photodynamic therapy (PDT). These photoproducts possess fluorescence and photosensitizing properties and could serve as a complementary dosimetry index alongside photosensitizer photobleaching. The formation of

Periodontitis and rheumatoid arthritis—Global efforts to untangle two complex diseases

Periodontology 2000, EarlyView.
Abstract Understanding the impact of oral health on rheumatoid arthritis (RA) will inform how best to manage patients with both periodontitis and RA. This review seeks to provide an update on interventional and mechanistic investigations, including a brief summary of European Research programs investigating the link between periodontitis and RA. Recent

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.

Root surface biomodification in periodontal therapy: Biological rationale and clinical applications

Periodontology 2000, EarlyView.
Abstract Regenerative periodontal therapy aims to form new cementum, periodontal ligament, and alveolar bone, all sealed by gingival tissue. The root surface acts as the wound margin during this regeneration process. Root surface biomodification (root conditioning/root decontamination), therefore, seems instrumental in promoting surface decontamination
