Hostperiodontitt

Hostperiodontitt is a term occasionally used in periodontal literature to describe a form of periodontitis in which the extent and speed of tissue destruction are driven predominantly by the host's inflammatory response to dental biofilm, rather than by bacterial virulence alone. The term is not universally adopted and may overlap with aggressive or refractory periodontitis, often emphasizing host factors as key determinants of progression.

Clinical features include rapid attachment loss, deep periodontal pockets, gingival recession, and tooth mobility, sometimes with minimal pain. Radiographic bone loss may appear extensive relative to local factors. Progression can occur over months rather than years, and responses to conventional therapy may be variable.

Etiology involves an interaction between the microbial biofilm and the host immune response. Genetic predisposition, systemic conditions such as diabetes, smoking, and age can modulate susceptibility, neutrophil function, cytokine profiles, and matrix degradation. The concept highlights host-modulation as a component of management alongside mechanical debridement.

Diagnosis relies on clinical periodontal examination, radiographs, and assessment of risk factors. Distinguishing from chronic or aggressive periodontitis may require evaluation of progression rate, family history, and potential biomarkers in gingival crevicular fluid. Differential diagnoses include other forms of periodontitis and systemic diseases with periodontal involvement.

Treatment and prognosis emphasize standard periodontal care with thorough debridement, local antimicrobial therapies when indicated, and control of risk factors (e.g., smoking cessation, glycemic control). Host-modulation therapies that aim to temper exaggerated inflammatory responses may be considered. Long-term prognosis depends on adherence to maintenance and ongoing risk-factor management.

Notes: the term is not widely standardized, and current understanding largely reflects descriptive and cohort-based observations of host response in periodontitis. See also periodontitis, host response modulation.
