Localized aggressive periodontitis - clinical, radiographic, microbiological and immunological findings

ABSTRACT

Introduction: Localized Aggressive Periodontitis (LAP) is characterized by a disease with rapid progression and loss of bone support specifically in the region of the permanent first molars and incisors teeth, and may lead to loss of dental elements. Objective: The aim of this study was to conduct a brief literature review on LAP, and present the clinical, radiographic, microbiological and immunological aspects of this rare form of periodontal disease. Literature review: Epidemiological studies in different populations showed a higher incidence in non-white population, and non-industrialized countries, there is also a predilection for female gender, manifested between puberty and 25 to 30 years of age. Conclusion: LAP is a disease with low prevalence, mainly caused by Aa, and radiographically manifested by extensive destruction of periodontal tissue supporting of permanent first molars and incisors. In contrast, clinically, the affected teeth not presented significant amount of dental biofilm or gingival inf lammation. The early diagnosis is important to establish an effective treatment, including antibiotic therapy, and favor prognosis.
