The $Papillon-Lef\`{e}vre$ Syndrome(PLS), a disease with autosomal recessive inheritance, is characterized by diffuse hyperkeratosis of the palms and soles, mostly prepubertal periodontitis and premature loss of primary and permanent dentition. The etiology of the destruction of periodontal tissues has not been completely clarified. In recent years, two main factors are suggested to be responsible for tooth loss ; firstly, the presence of gram negative microorganisms in the periodontal pockets of the patients. The other factor suggested is cellular deficiency in chemotaxic and phagocytic function of neutrophylic granulocytes. Resent data suggestes that mechanical debridement in conjunction with antibiotic therapy may be successful in periodontal management of $Papillon-Lef\`{e}vre$ Syndrome, particularly if administered early. In this study, a $Papillon-Lef\`{e}vre$ Syndrome patient was studied clinically, radiologically, histopathologically and microbiologically. 5 years female patient with gingival swelling and destruction of periodontal structure on the whole dentition were examined and palmar and plantar hyperkeratosis were can be seen. On microbiological analysis, Actinobacillus actino-mycetemcomitans was performed. Concurrently, the children recieved extraction of maxillary anterior teeth and construction of removable prosthetis. The combination of professional oral hygiene care and antibiotic therapy improved the dermatologic and periodontal condition.

Objectives: Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder. These patients lose their teeth at a young age and are in need of prosthetic rehabilitation. The aim of this systematic review was to assess the success of dental implant placement in these patients. Materials and Methods: An electronic search was performed in PubMed Central, Scopus, and Web of Science using the keyword "Papillon-Lefèvre syndrome" AND "dental implant" OR "prosthodontics". Articles reporting implant placement in patients with PLS until July 2019 were included. Results: Assessment of the included 11 articles reporting 15 cases showed 136 implant placements in these patients. Implant failure occurred in 3 patients (20 implants). The peri-implantitis and failure rate was higher in the maxilla. Meta-analysis showed the probability of failure to be 7% (95% confidence interval [CI] 0%-31%) for maxillary implants and 2% (95% CI 0%-9%) for mandibular implants. The follow-up time ranged between 1 and 20 years. Healing after bone graft and implant placement in these patients was uneventful. Conclusion: Dental implants may be a viable treatment option for PLS patients. Implantation can help preserve alveolar bone if the patients' immunological and growing conditions are well-considered and proper oral hygiene and compliance with the maintenance program are continued.

Chronic/cyclic neutropenia, leukocyte adhesion deficiency syndrome, Papillon-$Lef{\grave{e}}vre$ syndrome, and $Ch{\grave{e}}diak$-Higashi syndrome are associated with severe periodontitis, suggesting the importance of neutrophils in the maintenance of periodontal health. Various Toll-like receptor (TLR) ligands are known to stimulate neutrophil function, including FcR-mediated phagocytosis. In the present study, the effect of TLR2 activation on the non-opsonic phagocytosis of oral bacteria and concomitant production of reactive oxygen species (ROS) by human neutrophils was evaluated. Neutrophils isolated from peripheral blood were incubated with Streptococcus sanguinis or Porphyromonas gingivalis in the presence of various concentrations of $Pam_3CSK_4$, a synthetic TLR2 ligand, and analyzed for phagocytosis and ROS production by flow cytometry and chemiluminescence, respectively. $Pam_3CSK_4$ significantly increased the phagocytosis of both bacterial species in a dose-dependent manner. However, the enhancing effect was greater for S. sanguinis than for P. gingivalis. $Pam_3CSK_4$ alone induced ROS production in neutrophils and also increased concomitant ROS production induced by bacteria. Interestingly, incubation with P. gingivalis and $Pam_3CSK_4$ decreased the amounts of ROS, as compared to $Pam_3CSK_4$ alone, indicating the possibility that P. gingivalis survives within neutrophils. However, neutrophils efficiently killed phagocytosed bacteria of both species despite the absence of $Pam_3CSK_4$. Although P. gingivalis is poorly phagocytosed even by the TLR2-activated neutrophils, TLR2 activation of neutrophils may help to reduce the colonization of P. gingivalis by efficiently eliminating S. sanguinis, an early colonizer, in subgingival biofilm.
