Premature tooth loss is a disastrous situation that affects deciduous or permanent teeth era with different causes. It may be attributed to some disorders like Papillon-Lefevre syndrome or coffin-lowry syndrome but because of ambiguous nature, precise diagnosis is not easily possible. Moreover, it has very low incidence and defines by few and limited case series, with vague characters to some e...

Microbiological and serological (enzyme linked immunosorbent assay) investigations were carried out, including karyotyping, on two Asian children with Papillon-Lefèvre syndrome. In case 1, a girl aged four years, the most prevalent putative periodontopathogens were Eikenella corrodens, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia (deciduous dentition) and Bacteroides...

Papillon-Lefevre syndrome is a rare autosomal recessive disorder and is characterized by the diffuse palmoplantar hyperkeratosis with rapid destruction of the periodontal support of both the primary and secondary dentition. Patient is often completely or partially edentulous at the stage of primary (4-5 yrs) and permanent dentition (13-15 yrs). Though, exact etiopathogenesis is unknown; three m...

In a multilingual richly structured lexical data base such as Papillon, examples, citations, definitions and glosses expressed in each language have to be translated into all other languages and stored into the data base. Storing can be achieved in a simple and «!seamless!» way by introducing «!auxiliary» lexies and axies for these «!free language elements!». Translating all these elements into...

background: papillon-lefevre syndrome (pls) is a rare autosomal recessive disorder characterized by palmoplantar hyperkeratosis and early development of aggressive pe-riodontitis. although cathepsin c (ctsc) gene mutations have been established in about 70-80% of pls patients, it is assumed that the patients may have dysfunctioning of immune defense mechanisms. objective: to assess the associat...

Papillon Lefèvre syndrome is a rare disease characterized by skin lesions caused by palmar-plantar hyperkeratosis, and severe periodontal destruction involving both the primary and permanent dentitions. It is transmitted as an autosomal recessive condition and consanguinity of parents is evident in about one-third of cases. Pyogenic liver abscess is an increasingly recognized complication. We r...

Papillon- Lefèvre syndrome (PLS) is a rare autosomal recessive disorder of keratinization characterized by palmoplantar hyperkeratosis, periodontopathy and precocious loss of dentition. The exact pathomechanism of these clinical events mainly remains speculative. This paper describes two cases of PLS with classic clinical features and briefly review the relevant literature.
