Background: Periodontal diseases when persistent, results in periodontal pockets, attachment loss and progressive destruction of the alveolar bone. Grafting periodontal bone defects with bone substitute biomaterials has proven clinical success for accomplishing reconstruction of lost attachment apparatus, especially in deep intra-bony defects. Nanoparticles (NPs) have been considered indispensable in the future of health sciences and NP based alloplastic graft materials such as nanocrystalline hydroxyapatite (NCHA) hold great promise for regeneration of periodontal defects. Therefore the aim of this review is to evaluate the role of NCHA as an effective substitute for periodontal bone regeneration.
Material & Methods: Popular scientific databases such as PubMed (Medline), Cochrane database of clinical trials, Scopus (Elsevier), Web of science (Clarivate Analytics) and Google Scholar, were searched. The literature search was restricted to published reports in English, between January 2000 and December 2021. Database search returned 1227 results which were screened based on title, author names and publication dates.
Results: Data from the 14 included studies were reviewed and tabulated. In the present review, all the studies reported using commercially available NCHA for periodontal bone regeneration.
Conclusion: NCHA is a suitable bone substitute material for periodontal bone regeneration, with outcomes comparable to that of conventionally used graft materials such as bovine xenograft and other synthetic alloplastic materials. While grafting with NCHA in intrabony periodontal defects, after any form of periodontal flap surgery or debridement, significantly improves bone regeneration by 6 months, addition of adjuncts like EMD and PRF further enhance the outcomes.

Inflammatory bone resorption represents a pathological condition marked by an increase in bone loss, commonly associated with chronic inflammatory conditions such as rheumatoid arthritis and periodontitis. Current therapies primarily focus on anti-inflammatory drugs and bisphosphonates; however, these treatments are limited due to side effects, inadequate efficacy, and unpredictable long-term complications. Kurarinone (KR), a bioactive compound isolated from the traditional Chinese herb Sophora flavescens, exhibits a range of biological activities, including anti-inflammatory, anticancer, and cardiovascular protective effects.

Aim: To test a BiO-Optimizing Site Targeted (BOOST) approach to periodontal regeneration by the adjunctive use of locally delivered doxycycline (DOX) 2 weeks prior to minimally invasive surgery in terms of clinical and radiographic outcomes at 1 year.
Methods: For this randomized clinical trial, stage III/IV periodontitis patients presenting sites with intrabony defects and bleeding on probing (BoP+) after steps 1-2 of periodontal treatment were included. Sites were treated via subgingival instrumentation with or without a BOOST approach by local DOX.

Exosomes, small extracellular vesicles secreted by various cells, play crucial roles in the pathogenesis and treatment of oral diseases. Recent studies have highlighted their involvement in orthodontics, periodontitis, oral squamous cell carcinoma (OSCC), and hand, foot, and mouth disease (HFMD). Exosomes have a positive effect on the inflammatory environment of the oral cavity, remodeling and regeneration of oral tissues, and offer promising therapeutic options for bone and periodontal tissue restoration.

Background: Regenerating periodontal ligament (PDL) tissue is a vital challenge in dentistry that aims to restore periodontal function and aesthetics. This study explores a tissue engineering strategy that combines polycaprolactone (PCL)/collagen/cellulose acetate electrospun scaffolds with collagen hydrogels to deliver curcumin-loaded ZIF-8 nanoparticles fand periodontal ligament stem cells (PDLSCs).
Methods: Scaffolds were fabricated via electrospinningand collagen hydrogels incorporated PDLSCs and curcumin-loaded ZIF-8 nanoparticles (CURZIF-8) were developed using cross-linking.
