Article Synopsis
- The study investigates the impact of combining recombinant human fibroblast growth factor-2 (rhFGF-2) with β-tricalcium phosphate (β-TCP) on bone preservation after tooth extraction in dogs with dehiscence defects.
- The research involved extracting maxillary first premolars from six beagle dogs and comparing the bone volume and ridge widths at test sites (with rhFGF-2) against control sites (with only β-TCP) twelve weeks later.
- Results showed significantly greater bone volume and ridge widths in the test sites, suggesting that rhFGF-2 enhances alveolar ridge preservation in extraction sockets.
Objectives: To evaluate the effect of enamel matrix derivative in liquid form (EMD-liquid) as adjunct to grafting with natural bovine bone (NBB), on new bone formation and osseointegration in buccal dehiscence defects at dental implants.
Material And Methods: In six beagles, 3 months after extraction of the mandibular premolars and first molars. Three titanium implants (3.

The aim of this study was to examine effects of recently developed ultraviolet light-emitting diodes (UV LEDs) wavelengths on growth and gene expression of cultural periodontopathic bacteria, and on viability of experimental gingival fibroblasts. , , , , and were irradiated by UV LEDs (265, 285, 310, 365, and 448 nm) at 600 mJ/cm and grown anaerobically . The colony forming units were counted after 1 week.

This study aims to comparatively evaluate the potential for ridge preservation in extraction sockets with buccal bone deficiency of β-tricalcium phosphate coated with poly lactide-co-glycolide (β-TCP/PLGA) and conventional particulate β-TCP.
Methods: In six beagles, maxillary first premolars were extracted after removal of their buccal bone plates.
Background And Objective: It is well known that recombinant human fibroblast growth factor-2 (rhFGF-2) signaling plays an important role in tissue repair and regeneration. rhFGF-2 strongly binds to acidic gelatin via ionic linkages and is gradually released upon gelatin decomposition. On the other hand, the linkage between rhFGF-2 and basic gelatin is so weak that most rhFGF-2 is rapidly released from basic gelatin by simple desorption.

- The study investigated the effects of enamel matrix derivatives (EMD) on healing after nonsurgical periodontal treatment following the induction of periodontal breakdown in beagle dogs.
- No significant differences were found in probing pocket depth (PPD) and clinical attachment level (CAL) between EMD and control groups, but the EMD sites showed more new cementum and less epithelial growth.
- Overall, the research suggests that EMD may enhance new cementum formation and reduce epithelial growth during nonsurgical periodontal treatment.
Background: Reduction in alveolar ridge volume is a direct consequence of tooth extraction. Tunnel β-tricalcium phosphate (β-TCP) blocks were manufactured from randomly organized tunnel-shaped β-TCP ceramic. Efficacy of these blocks compared to extraction alone for alveolar ridge preservation after tooth extraction with buccal bone deficiency was evaluated.
