Special Issue Information

Dear Colleagues,

Oral diseases represent a significant global health challenge, affecting billions worldwide and imposing a profound impact on overall health, quality of life, and the economy. Central to the development and persistence of many oral diseases is the role of biofilms, the complex microbial communities that adhere to surfaces in the oral cavity and exhibit increased resistance to conventional treatments. These resilient biofilms are key contributors to a spectrum of oral conditions, including dental caries, periodontal diseases, peri-implant infections, and endodontic lesions. Furthermore, the intricate interplay between biofilms and host factors plays a critical role in disease pathogenesis and progression.

This Special Issue, Biofilm-Associated Oral Diseases: Advances in Diagnosis and Challenges in Treatment, seeks to advance our understanding of the mechanisms underlying biofilm-associated oral diseases and to explore innovative diagnostic and therapeutic strategies to overcome current challenges. This Special Issue aims to cover recent advancements in

  • The role of host–biofilm interactions in disease progression and resolution.
  • The molecular and ecological dynamics of oral biofilms.
  • Novel antimicrobial strategies to combat biofilm resilience.
  • Personalized treatment approaches based on microbial profiling.

We welcome contributions that address the multifaceted nature of oral biofilms, including original research, clinical studies, reviews, and case reports. By integrating scientific and clinical perspectives, this Special Issue aims to provide a comprehensive resource for researchers, clinicians, and policymakers dedicated to mitigating the burden of biofilm-associated oral diseases.

Together, let us advance the field of oral health by addressing the persistent challenges posed by biofilm-related diseases through innovative, evidence-based solutions.

Background/Objectives: The essential trace element zinc (Zn) has a pivotal role in wound healing and can show antibacterial activity, but its application in oral implant materials is underexplored. Customized healing abutments can modulate the peri-implant tissue health when appropriate bioactive materials promoting mucosal healing are used. The present study investigated a novel Zn-containing polymer for its potential in soft-tissue engineering applications. Methods: Four traditional materials—titanium, glass ionomer, a composite, and the novel Zn-containing polymer—were tested in vitro for bacterial growth using a multispecies oral bacterial model compared to hydroxyapatite. The biocompatibility of the materials was also evaluated by evaluating the adhesion, proliferation, and cytotoxicity of human oral keratinocytes (HOK-18A) onto these materials, compared to tissue culture plastic. Results: The Zn-containing polymer exhibited a significantly lower biofilm formation compared to conventional materials as it was composed of less pathogenic bacteria. The Zn-containing material also demonstrated a superior biocompatibility towards HOK-18A, approximating the adhesion and proliferation of the keratinocytes to optimal tissue culture conditions. Moreover, these properties did not seem to degrade and were maintained over a period of 31 days. The cytotoxicity assessment revealed no significant reduction in metabolic activity for any material. Conclusions: This study highlights the potential of the novel Zn-containing polymer in soft-tissue engineering, owing to its antimicrobial and biocompatible assets. These properties, combined with the ease of chairside modeling, position the material as a promising alternative for creating customized healing abutments. Further research is needed to explore its mechanism of wound healing modulation and its clinical performance. Full article
