Abstract
Neutrophils perform essential functions in antimicrobial defense and tissue maintenance at mucosal barriers. However, a dysregulated neutrophil response and, in particular, the excessive release of neutrophil extracellular traps (NETs) are implicated in the pathology of various diseases. In this review, we provide an overview of the basic concepts related to neutrophil functions, including NET formation, and discuss the mechanisms associated with NET activation and function in the context of the prevalent oral disease periodontitis.

Abstract
AIMS The oral microbiota composition of patients diagnosed with Papillon-Lefèvre-syndrome and treated for several years were compared to those existing in the oral cavity of the clinically healthy family members and a cohort of patients having various stages of chronic periodontitis. MATERIALS AND METHODS A family with two sisters affected with severe periodontitis and with the typical skin symptoms of Papillon-Lefèvre-syndrome, and symptomless parents and third sibling were investigated. The Patients received periodontal treatment for several years and their oral microbiome was analysed by amplicon sequencing. Data were evaluated by microbial cluster analysis. RESULTS The microbiome of the patients with Papillon-Lefèvre-syndrome was predominated with Aggregatibacter actinomycetemcomitans and associated oral periodontopathogens. Although the clinically healthy family members showed no oral disorder, their microbiome resembled that of subjects having mild periodontitis. CONCLUSIONS Predominance of A. actinomycetemcomitans in the subgingival microbiome of patients with Papillon-Lefèvre-syndrome suggests that specific treatment strategies directed against this pathobiont may improve the oral health status of the affected individuals. TRIAL REGISTRATION The study was conducted in accordance with the Declaration of Helsinki and the ethical permission has been issued by the Human Investigation Review Board of the University of Szeged, Albert Szent-Györgyi Clinical Centre (Permission No. 63/2017-SZTE).

Abstract
Papillon-Lefevere syndrome (PLS) is a rare disorder with severe oral manifestations resulting in premature tooth loss at an early stage of life. As a result, extensive bone resorption pattern in the maxilla negates conventional implant treatment in the majority of cases. This clinical report describes a prosthetic rehabilitation revision of a 26-year-old female diagnosed with PLS using an implant supported fixed complete denture with a quad zygoma approach. A 1 year follow-up is also presented.

Subsiding of Periodontitis in the Permanent Dentition in Individuals with Papillon-Lefèvre Syndrome through Specific Periodontal Treatment: A Systematic Review. Healthcare (Basel) 2022; 10:healthcare10122505. [PMID: 36554029 PMCID: PMC9778266 DOI: 10.3390/healthcare10122505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 12/02/2022] [Accepted: 12/05/2022] [Indexed: 12/14/2022] Open
Abstract
Papillon-Lefèvre syndrome (PLS) is a rare hereditary disease characterized by palmoplantar hyperkeratosis (PPK) and periodontitis in the primary and permanent dentition, usually resulting in edentulism in youth. Subsiding of PLS-associated periodontitis through specific therapy has occasionally been reported. We aimed to systematically assess periodontal treatment strategies that may decelerate disease progression. A systematic literature search was conducted at PubMed/LIVIVO/Ovid (Prospero registration number CRD42021223253). Clinical studies describing periodontal treatment success-defined as loss of ≤four permanent teeth because of periodontitis and the arrest of periodontitis or probing depths ≤ 5 mm-in individuals with PLS followed up for ≥24 months. Out of the 444 primarily identified studies, 12 studies reporting nine individuals were included. The timely extraction of affected or, alternatively, all primary teeth, compliance with oral hygiene instructions, supra- and subgingival debridement within frequent supportive periodontal care intervals, and-in eight patients-adjunctive systemic antibiotic therapy (mostly amoxicillin/metronidazole) effected a halt in disease progression. The suppression of Aggregatibacter actinomycetemcomitans below the detection limit was correlated with the subsiding of periodontitis. Successful controlling of PLS-associated periodontitis may be achieved if high effort and patient compliance are provided.

Abstract
INTRODUCTION Inherited phagocyte defects are one of the subgroups of primary immunodeficiency diseases (PIDs) with various clinical manifestations. As oral manifestations are common at the early ages, oral practitioners can have a special role in the early diagnosis. MATERIALS AND METHODS A comprehensive search was conducted in this systematic review study and data of included studies were categorized into four subgroups of phagocyte defects, including congenital neutropenia, defects of motility, defects of respiratory burst, and other non-lymphoid defects. RESULTS Among all phagocyte defects, 12 disorders had reported data for oral manifestations in published articles. A total of 987 cases were included in this study. Periodontitis is one of the most common oral manifestations. CONCLUSION There is a need to organize better collaboration between medical doctors and dentists to diagnose and treat patients with phagocyte defects. Regular dental visits and professional oral health care are recommended from the time of the first primary teeth eruption in newborns.

Abstract
The field of primary immunodeficiencies (PIDs) is rapidly evolving. Indeed, the number of described diseases is constantly increasing thanks to the rapid identification of novel genetic defects by next-generation sequencing. PIDs are now rather referred to as “inborn errors of immunity” due to the association between a wide range of immune dysregulation-related clinical features and the “prototypic” increased infection susceptibility. The phenotypic spectrum of PIDs is therefore very large and includes several orofacial features. However, the latter are often overshadowed by severe systemic manifestations and remain underdiagnosed. Patients with impaired innate immunity are predisposed to a variety of oral manifestations including oral infections (e.g., candidiasis, herpes gingivostomatitis), aphthous ulcers, and severe periodontal diseases. Although less frequently, they can also show orofacial developmental abnormalities. Oral lesions can even represent the main clinical manifestation of some PIDs or be inaugural, being therefore one of the first features indicating the existence of an underlying immune defect. The aim of this review is to describe the orofacial features associated with the different PIDs of innate immunity based on the new 2019 classification from the International Union of Immunological Societies (IUIS) expert committee. This review highlights the important role played by the dentist, in close collaboration with the multidisciplinary medical team, in the management and the diagnostic of these conditions.

Abstract
Periodontitis is a common human inflammatory disease. In this condition, microbiota trigger excessive inflammation in oral mucosal tissues surrounding the dentition, resulting in destruction of tooth-supporting structures (connective tissue and bone). While susceptibility factors for common forms of periodontitis are not clearly understood, studies in patients with single genetic defects reveal a critical role for tissue neutrophils in disease susceptibility. Indeed, various genetic defects in the development, egress from the bone marrow, chemotaxis, and extravasation are clearly linked to aggressive/severe periodontitis at an early age. Here, we provide an overview of genetic defects in neutrophil biology that are linked to periodontitis. In particular, we focus on the mechanisms underlying Leukocyte Adhesion Deficiency-I, the prototypic Mendelian defect of impaired neutrophil extravasation and severe periodontitis.

Abstract
Lysosomal cathepsins are proteolytic enzymes increasingly recognized as prognostic markers and potential therapeutic targets in a variety of diseases. In those conditions, the cathepsins are mostly overexpressed, thereby driving the respective pathogenic processes. Although less known, there are also diseases with a genetic deficiency of cathepsins. In fact, nowadays 6 of the 15 human proteases called 'cathepsins' have been linked to inherited syndromes. However, only three of these syndromes are typical lysosomal storage diseases, while the others are apparently caused by defective cleavage of specific protein substrates. Here, we will provide an introduction on lysosomal cathepsins, followed by a brief description of the clinical symptoms of the various genetic diseases. For each disease, we focus on the known mutations of which many have been only recently identified by modern genome sequencing approaches. We further discuss the effect of the respective mutation on protease structure and activity, the resulting pathogenesis, and possible therapeutic strategies.

Abstract
Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder, characterized by diffuse palmoplantar keratoderma and precocious aggressive periodontitis, leading to premature loss of deciduous and permanent dentition at a very young age. Various etiopathogenic factors are associated with the syndrome, like immunologic alterations, genetic mutations, and the role of bacteria. Dentists play a significant role in the diagnosis and management of PLS as there are characteristic manifestations like periodontal destruction at an early age and an early eruption of permanent teeth. Here, we are presenting an elaborate review of PLS, its etiopathogenesis, clinical presentation, and management options.

Abstract
BACKGROUND Generalised aggressive periodontitis (AP) in the prepubescent age is an exceptionally rare disease in the primary dentition of otherwise healthy children. Characteristics of AP are gingival inflammation, deep periodontal pockets, bone loss, tooth mobility and even tooth loss. The most common way of treating this disease is the extraction of all the involved primary teeth. CASE REPORT A 4-year-old girl presented with signs of severe gingival inflammation. Clinical examination revealed deep pockets, increased tooth mobility and bone loss. Microbiological testing revealed the presence of a typical periopathogenic flora consisting of Aggregatibacter actinomycetemcomitans and the typical members of the red complex (Porphyromonas gingivalis, Prevotella intermedia and Treponema denticola). The patient underwent tooth extraction of all primary teeth except the primary canines, followed by thorough root debridement and treatment with systemic antibiotics (amoxicillin plus metronidazole). FOLLOW-UP Regular clinical and microbiological examinations over 4 years showed no signs of recurrence of a periodontitis, even in the erupted permanent teeth. CONCLUSION Early diagnosis and consequent early treatment of aggressive periodontitis can stop the disease and therefore avoid the development of a periodontal disease in the permanent dentition. A close collaboration between specialists of different disciplines is required for a favourable outcome.

Abstract
Papillon-lefevre syndrome (PLS) belongs to a heterogeneous group of skin diseases that are characterized by hyperkeratosis of palms and soles. It is a type IV palmoplantar keratosis (PPK) while the palmoplantar keratodermas share some features of PPK, they are etiologically heterogeneous. PLS differs from other types of PPK by the presence of severe and early onset periodontitis. Genetic studies have shown that mutation in the major gene locus of chromosome 11q14 with the loss of function of cathepsin-C (CTSC) gene is responsible for PLS. CTSC gene mutations are causative for PLS. The resultant loss of CTSC function is responsible for the severe periodontal destruction seen clinically. This report represents two siblings with classical signs and symptoms of PLS.

Abstract
Periodontitis is an infectious disease with marked inflammatory response, leading to destruction of underlying tissues. The aim of periodontal therapy is to eradicate the pathogens associated with the disease and attain periodontal health. This is achieved by non-surgical and surgical therapy; however, mechanical debridement and topical application of antiseptics may not be helpful in all cases. In such cases, adjunctive systemic antibiotic therapy remains the treatment of choice. It can reach micro-organisms at the base of the deep periodontal pockets and furcation areas via serum, and also affect organisms residing within gingival epithelium and connective tissue. Before advising any anti-microbial agent, it is necessary to have knowledge of that agent. The aim of this review article is to provide basic details of each systemic anti-microbial agent used in periodontal therapy. The points discussed are its mode of action, susceptible periodontal pathogens, dosage, its use in treatment of periodontal disease, and mechanism of bacterial resistance to each anti-microbial agent. It might be of some help while prescribing these drugs.

Abstract
Papillon-Lefevre Syndrome (PLS) is a very rare autosomal recessive disorder characterized by palmoplantar hyperkeratosis and severe early onset periodontitis, affecting the primary and permanent dentition. The syndrome was first described by Papillon and Lefevre in 1924. Genetic, immunologic, and microbiologic factors are suggested as responsible for the initiation and progression of the disease. A point mutation of cathepsin C gene has recently been detected in PLS. A multidisciplinary approach is important for management .The prognosis has improved with the early recognition of the syndrome, effective professional supervision, and home care.

Abstract
Papillon-Lefèvre syndrome (PLS) is characterised by aggressively progressive periodontitis combined with palmo-plantar hyperkeratosis. It is caused by "loss of function" mutations in the cathepsin C gene. The hypothesis behind this study is that PLS patients' polymorphonuclear leukocytes (PMNs) produce more proinflammatory cytokines to compensate for their reduced capacity to neutralize leukotoxin and to eliminate Aggregatibacter actinomycetemcomitans. Production of more interleukin (IL)-8 would result in the attraction of more PMNs. The aim of this study was to evaluate the cytokine profile in PLS patients' blood cultures. Blood was sampled from eight PLS patients (one female) from six families (antiinfective therapy completed: six; edentulous: two) with confirmed cathepsin C mutations and deficient enzyme activity. Nine healthy males served as controls. Whole blood cultures were stimulated with highly pure lipopolysaccharide (LPS) from Escherichia coli R515 and IL-1β plus tumor necrosis factor (TNF)-α. Thereafter, release of IL-1β (stimulation: LPS and LPS plus adenosine triphosphate), IL-6, IL-8, interferon-inducible protein (IP)-10, and interferon (IFN)-γ (stimulation: LPS, IL-1β/TNFα) were detected by ELISA. Medians of cytokine release were, with the exception of IP-10, slightly higher for PLS than for controls' cultures. None of these differences reached statistical significance. Increased production of IL-1β, IL-6, IL-8, IP-10, or IFNγ as a significant means to compensate for diminished activity and stability of polymorphonuclear leukocyte-derived proteases could not be confirmed in this study. Cytokine profiles in blood cultures may not be used to identify PLS patients.

Abstract
BACKGROUND Papillon-Lefèvre syndrome (PLS) is an autosomal recessive disease characterized by hyperkeratosis of the palms and soles combined with premature loss of the primary and permanent dentition. Several treatment regimens have been recommended in the literature; however, a definitive treatment protocol has not been established. This case report evaluates the success of combined therapy in managing a patient with PLS. METHODS A 6-year-old girl diagnosed with PLS presented with aggressive periodontal destruction of her primary and permanent dentitions. After extraction of periodontally affected teeth, the edentate region was rehabilitated with different temporary dentures until her skeletal growth was complete. At the same time, her orthodontic treatment was performed. The early loss of her incisors resulted in inadequate alveolar bone height and width for esthetic-advanced prosthetic rehabilitation. Alveolar bone augmentation was performed, and 6 months later, two intraosseous dental implants were placed into the central incisor zone. RESULTS After 13 years of treatment and follow-up, the patient had periodontally healthy permanent dentition. She had practiced meticulous oral hygiene, and the orthodontic treatment was successful and without incident. Alveolar ridge augmentation and placement of an intraosseous implant with guided bone regeneration were performed successfully. CONCLUSIONS This case report demonstrates that individually developed treatment protocols can provide long-term dental/periodontal success in patients with PLS. A multidisciplinary approach with advanced periodontal surgery, orthodontic and prosthetic treatment, and implant therapy may be an appropriate treatment modality for dental rehabilitation in patients with PLS.

Abstract
OBJECTIVE Report of clinical and microbiological periodontal findings before and 6 months after treatment of two siblings with Papillon-Lefèvre syndrome (PLS) and tinea capitis. METHODS Two brothers, RG 3 years and NG 5 years of age, were referred for treatment due to premature mobility of their deciduous teeth. Probing depths (PPD), attachment levels (PAL-V), and furcation involvements were examined clinically. Panoramic radiographs were taken. Subgingival plaque samples within the deepest pocket of each tooth were taken and analysed by real-time polymerase chain reaction (PCR) for Actinobacillus actinomycetemcomitans (AA), Porphyromonas gingivalis, Tannerella forsythensis, Treponema denticola, Fusobacterium nucleatum, and Prevotella intermedia. One-stage full-mouth scaling and extraction of hopeless teeth were performed under general anaesthesia, followed by systemic amoxicillin and metronidazole for 7 days. Clinical and microbiological analyses were performed 6 months after treatment. RESULTS Before treatment, both siblings had exhibited PPD of up to 13 mm, Class III furcation defects at four teeth, and marginal suppuration. AA was detected in both patients and at all teeth at levels ranging from 3.0 x 10(2) to 5.1 x 10(6). Both patients exhibited palmar and plantar hyperkeratosis. Seven teeth were extracted from RG, and nine from NG. Six months after treatment, PPD had been reduced to <or=5 mm. AA was not detected in any of the remaining teeth. CONCLUSION Even periodontally affected deciduous teeth of PLS patients can be treated successfully. Suppression of AA to below detection level seems to be of high significance.

Abstract
Periodontitis is a chronic destructive infection of the tooth-supportive tissues, which is caused by pathogenic bacteria such as Actinobacillus actinomycetemcomitans. A severe form of periodontitis is found in Papillon-Lefèvre syndrome (PLS), an inheritable disease caused by loss-of-function mutations in the cathepsin C gene. Recently, we demonstrated that these patients lack the activity of the polymorphonuclear leukocyte (PMN)-derived serine proteinases elastase, cathepsin G, and proteinase 3. In the present study we identified possible pathways along which serine proteinases may be involved in the defense against A. actinomycetemcomitans. Serine proteinases are capable to convert the PMN-derived hCAP-18 into LL-37, an antimicrobial peptide with activity against A. actinomycetemcomitans. We found that the PMNs of PLS patients released lower levels of LL-37. Furthermore, because of their deficiency in serine proteases, the PMNs of PLS patients were incapable of neutralizing the leukotoxin produced by this pathogen, which resulted in increased cell damage. Finally, the capacity of PMNs from PLS patients to kill A. actinomycetemcomitans in an anaerobic environment, such as that found in the periodontal pocket, seemed to be reduced. Our report demonstrates a mechanism that suggests a direct link between an inheritable defect in PMN functioning and difficulty in coping with a periodontitis-associated pathogen.

Abstract
BACKGROUND Langerhans' cell histiocytosis (LCH) is a rare disorder characterized by Langerhans' cell proliferation in various organs or tissues. When periodontal tissue is involved, clinical manifestations can vary from gingival recession and pocket formation to severe alveolar bone loss. This case report describes periodontal pathogens found in the pockets of involved primary teeth. METHODS A 5-year-old girl with LCH presented with loose teeth. Intraoral examination and radiographs revealed deep pockets and severe bone loss around all primary molars. Bacterial samples were obtained from saliva and subgingival plaque and analyzed for the presence of five periodontopathic bacteria using a polymerase chain reaction (PCR) method. Due to severe periodontal destruction, all primary molars were extracted, and a gingival biopsy was taken from tooth T to confirm the diagnosis of LCH. RESULTS The biopsy specimen revealed the histologic features of LCH. The patient was diagnosed as having periodontitis as a manifestation of LCH. PCR results of subgingival plaque from LCH-affected molars indicated the presence of Porphyromonas gingivalis, Tannerella forsythensis, Treponema denticola, and Prevotella intermedia. However, Actinobacillus actinomycetemcomitans was absent from these teeth. No tested bacteria were found in the non-affected anterior teeth. CONCLUSIONS The bacteria commonly associated with periodontal disease were detected in subgingival plaque samples from this LCH patient. More microbiological data are required to understand the role of these bacteria in LCH-associated periodontal destruction.

Abstract
A 7-year-old boy born to consanguineous parents had suffered from palmoplantar keratoderma and chronic gingivitis since the age of 3 months. He was diagnosed with Papillon-Lefèvre syndrome. Genetic testing confirmed that he was homozygous with a point mutation in exon 6 of the cathepsin C gene. One year after initiating treatment with acitretin 10 mg oral daily and trimethoprim-sulfamethoxazole, the patient's skin remains almost lesion-free, and he has new teeth that erupted during treatment and are free of periodontal disease.

Abstract
This article provides an overview of periodontal disease diagnosis that uses clinical parameters and biomarkers of the disease process.This article discusses the use of biomarkers of disease that can be identified at the tissue, cellular, and molecular levels and that are measurable in oral fluids such as saliva and gingival crevicular fluid. Biomarkers identified from these biologic fluids include microbial, host response, and connective tissue-related molecules that can target specific pathways of local alveolar bone resorption. Future prospects for oral fluid-based diagnostics that use micro-array and microfluidic technologies are presented.

Abstract
BACKGROUND Report of a combined periodontal and orthodontic treatment in a patient with Papillon-Lefevre Syndrome (PLS). METHODS A patient with PLS was treated orthodontically 26 months after the start of a combined mechanical and antibiotic therapy. Clinical periodontal parameters were obtained 26 (t1), 60 (t2), and 79 (t3) months after anti-infective therapy. The deepest site of each tooth was sampled for microbiological analysis at 26 and 60 months. Periodontal maintenance therapy was provided every 6 weeks. After a stable periodontal situation was achieved, orthodontic treatment, consisting of space opening for the upper canines with a multibracket appliance and coil springs, was carried out. In the lower jaw, crowding was resolved by an orthodontic mesialization of the canines. RESULTS Twenty-six months (t1) after the beginning of the combined mechanical and antibiotic therapy, 6% of the sites exhibited 4 mm probing depth (PD) with bleeding on probing (BOP) or PD > or =5 mm. Sixty months (t2) after therapy the number of sites with 4 mm PD with BOP or PD > or =5 mm had increased to 17%, and 79 months after therapy (t3) 13% of all sites were similarly affected. From 26 to 60 months, a slight mean clinical attachment level (CAL) gain was observed, whereas the mean PD increased. From 60 to 79 months, there was a mean PD reduction. However, a significant mean attachment loss was also noted. After 26 months (t1), RNA probes failed to detect A. actinomycetemcomitans, P. gingivalis, or T. forsythensis from any site. Thirty-four months later (t2), subgingival recolonization was observed. A. actinomycetemcomitans was detected by RNA probes at three sites. At 26 and 60 months (t1, t2), trypticase-soy with serum, bacitracin, and vancomycin (TSBV) culture failed to detect A. actinomycetemcomitans at any of the sampled sites. Eighty-two months after the beginning of therapy (t4), none of the applied methods could detect A. actinomycetemcomitans from the pooled samples from the deepest pockets of each quadrant or the oral mucosa. In the present case, concomitant orthodontic treatment with a fixed appliance could be performed without further pronounced periodontal deterioration. Space for eruption of the canines and premolars was created, in addition to an alignment of the teeth. CONCLUSION After a successful combined mechanical and antibiotic periodontal therapy of the PLS periodontitis, moderate orthodontic tooth movements may be possible within a complex interdisciplinary treatment regimen.

Abstract
BACKGROUND/AIM Conventional mechanical periodontal treatment of Papillon-Lefevre syndrome (PLS) has often been reported to fail. This study describes the outcome of a non-surgical periodontal therapy including antimicrobial treatment of nine patients diagnosed with PLS. The patients originate from a total of 15 children and adolescents with PLS for which clinical characteristics are presented. METHODS Clinical examination including conventional periodontal measurements. Initial treatment including oral hygiene instruction, scaling and root planing and systemic amoxicillin-metronidazole therapy for 6 weeks. After that the patients were enrolled in a 3-month recall maintenance program. In addition to this mechanical supportive maintenance treatment, tetracycline was prescribed and used continuously for 1.5 years. RESULTS/CONCLUSION On five patients who were showing acceptable standard of oral hygiene and also compliance with the antibiotic medication, development of periodontitis on erupting teeth was prevented and disease activity on the previously periodontally involved teeth controlled during a 3-year period. Poor results of treatment were observed for three patients, all siblings. These patients failed to comply with the medication and also failed to improve their oral hygiene.

Abstract
BACKGROUND Our understanding of the complexity of the oral microbiota continues to improve as new technologies, such as the analysis of 16S rRNA bacterial genes, are utilized. Despite the difficult of cataloguing all microorganisms and determining their pathogenic potential, some species, mostly members of the resident oral microbiota, have been identified as likely periodontal pathogens. However, for microbial diagnosis to be of value, it needs to affect disease diagnosis and/or treatment planning as well as result in superior treatment outcomes and/or provide an economic benefit to the patient. RATIONALE The purposes of this systematic review were to determine if microbial identification influences periodontal patient management and whether treatment outcomes are better compared to patients whose treatment plans are developed without this information. FOCUSED QUESTION In patients with periodontal diseases, does microbial identification influence patient management compared to treatment prescribed without this information? SEARCH PROTOCOL The MEDLINE database was searched for clinical studies in English from 1991 through 2002 by 2 investigators. Hand searches were performed on the Journal of Clinical Periodontology, Journal of Periodontology, Journal of Periodontal Research, Oral Microbiology and Immunology, and Periodontology 2000. In addition, directors of diagnostic laboratories were contacted about unpublished data. SELECTION CRITERIA INCLUSION CRITERIA Articles in which bacterial identification influenced patient treatment were preferred as were those reporting longitudinal data demonstrating a direct relationship between the presence or absence of certain bacteria and subsequent alterations in clinical variables. Because of the limited number of studies, all articles, including case reports, were considered. EXCLUSION CRITERIA Review articles without original data were excluded, although references were examined for possible inclusion. Articles reporting data showing associations between certain microorganisms and disease or health that did not affect treatment were excluded. Clinical trials testing antibacterial agents for their ability to enhance mechanical debridement were not included since bacterial identification had little effect on drug selection or experimental group assignment. Articles dealing with implants rather than natural teeth were omitted. DATA ANALYSIS AND COLLECTION: The heterogeneity of the published data precludes any meaningful pooling of data or meta-analysis. The pertinent literature, including relevant variables of plaque, gingivitis, and bleeding on probing scores; probing depth; clinical attachment level; number of lost teeth; and microbial changes; and patient-centered outcomes including decrease in morbidity, reduced need for surgery, and duration and cost of treatment are summarized. MAIN RESULTS 1. There was a lack of articles with a high evidence rating; most pertinent articles were either case reports or case series without controls. 2. Because reports were heterogeneous regarding study design, patient selection, and data collection, meta-analysis was not feasible and results are summarized in tabular format. 3. This report is based on a total of 24 studies, representing a total patient population of approximately 835. 4. Thirteen studies reported on microbiological identification as an aid in treatment planning. 5. Eleven studies reported a differential clinical response depending on the detection or lack of detection of specific organisms. REVIEWERS' CONCLUSIONS 1. The published material suggests that microbiological monitoring may be useful in management of selected patients who do not respond to standard therapy. 2. Some practitioners consider microbial identification a valuable adjunct to managing patients with certain forms of periodontitis, although there is a lack of strong evidence to this effect. 3. Additional research is needed to address this issue.

Abstract
BACKGROUND A 5-year-old Japanese boy presented with persistent gingival inflammation and severe mobility of the right lower primary incisors. Due to severe alveolar bone loss and a deep periodontal pocket (5 mm), the incisors were extracted at the second visit. METHODS Clinical, radiographic, histological, and microbiological examinations were carried out. Then, the polymerase chain reaction (PCR) technique was employed to detect specific periodontal pathogens. The chemotactic activity of polymorphonuclear neutrophils was also measured. RESULTS Tannerella, Capnocytophaga, Fusobacterium, and Eikenella sp. were recovered from the subgingival microflora around the right lower incisors, while A. actinomycetemcomitans, Tannerella forsythensis (formerly Bacteroides forsythus), Prevotella nigrescens, Campylobacter rectus, and Capnocytophaga gingivalis were detected using the PCR method. Further chemotaxis assay revealed that neutrophil function was depressed compared with that of healthy controls. CONCLUSIONS Although inflammation remained around the right primary second molars, the bone loss was controlled by periodic professional mechanical teeth cleaning (PMTC), subgingival irrigation, and local antibiotic application. The probing depths of all teeth, including permanent incisors and molars, were within 2.5 mm.

Abstract
The terms 'early onset periodontitis' (EOP) and 'juvenile periodontitis' (JP) were replaced by that of 'aggressive periodontitis' in a recent international workshop for the classification of periodontal diseases and conditions. The chief etiologic agent for aggressive periodontitis is considered to be Actinobacillus actinomycetemcomitans in localized juvenile periodontitis. Porphyromonas gingivalis is also mentioned as the etiologic agent of the aggressive periodontitis, although to date its role remains questionable. This communication describes three cases of aggressive periodontitis found to be associated with P. gingivalis but not A. actinomycetemcomitans by polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA). Our findings clarify the role of P. gingivalis as an etiologic agent in this type of periodontitis and confirm its inclusion in the current definition of aggressive periodontitis.

Abstract
The cytocidal effect of seven macrolide antibiotics on human periodontal ligament fibroblasts (Pel cells) was studied. Pel cells were exposed for 48 h to erythromycin (EM), clarithromycin (CAM), roxithromycin (RXM), azithromycin (AZM), josamycin (JM), midecamycin (MDM), and rokitamycin (RKM), and allowed to form colonies. The cytocidal effect of the macrolides was measured as a decrease in colony-forming efficiency and was found to increase with the concentration. To obtain a quantitative measure of the cytocidal effect, the LD50, i.e. the concentration that decreases colony-forming efficiency 50% relative to control cells, was extrapolated from the concentration-response curves. The rank of the macrolides according to their cytocidal effect (LD50) was RKM > RXM > CAM > AZM > JM > MDM approximately EM. RKM, RXM, CAM, AZM, and JM were at least 1.7-12.2 times more cytocidal than MDM or EM. When extrapolated from the concentration-response curves, the relative survival of the Pel cells exposed to each of the macrolides at the MIC90 concentrations for periodontopathic bacteria was estimated to be: > or = 53.8% for RKM, > or = 92.7% for RXM, > or = 94.6% for CAM, > or = 97.1% for AZM, and > or = 86.2% for EM. The effect of the antibiotics on the mRNA expression of alkaline phosphatase (ALP) and type I procollagen (COL) was examined in Pel cells exposed for 48 h to RXM, CAM, AZM, and EM, which exhibited strong, moderate, and weak cytocidal activity. The constitutive levels of both ALP and COL mRNA were retained in cells exposed to RXM at < or = 3 microM, CAM at < or = 10 microM, and AZM or EM at < or = 3 microM. The MIC90 against periodontopathic bacteria is < or = 4.8 microM for RXM, 5.3 microM for CAM, 2.7 microM for AZM, and 21.8 microM for EM. These results suggest that topical administration of CAM or AZM to the gingival crevice at their MIC90 concentration for periodontopathic bacteria would have little adverse effect on the growth and differentiation of the periodontal ligament. It is important to note, however, that these findings have yet to be extrapolated to in vivo conditions.

Abstract
BACKGROUND, AIMS Conventional mechanical treatment of Papillon-Lefèvre syndrome periodontitis has a poor prognosis. This report describes an effective antimicrobial treatment of rapidly progressing periodontitis in an 11-year old girl having Papillon-Lefèvre syndrome. METHOD Clinical examination included conventional periodontal measurements and radiographic analysis. Occurrence of major suspected periodontopathic bacteria was determined by selective and non-selective culture and by polymerase chain reaction (PCR) identification. Presence of cytomegalovirus and Epstein-Barr type 1 virus was determined by a nested-PCR detection method. Therapy included scaling and root planing, oral hygiene instruction, and systemic amoxicillin-metronidazole therapy (250 mg of each/3 times daily/10 days) which, based on follow-up microbiological testing, was repeated after 4 months. Supportive periodontal therapy took place at 2 visits during a 16-month period. RESULTS At baseline, 10 of 22 available teeth demonstrated severe periodontal breakdown. At 16 months, probing and radiographic measurements revealed no teeth with additional attachment loss, and several teeth exhibited significant reduction in gingivitis and pocket depth, increase in radiographic alveolar bone height and clinical attachment level, and radiographic evidence of crestal lamina dura. Baseline subgingival microbiota included Actinobacillus actinomycetemcomitans (3.4% of total isolates), Prevotella nigrescens (16.4%), Fusobacteriumnucleatum (14.3%) and Peptostreptococcus micros (10.6%), as well as cytomegalovirus and Epstein-Barr type 1 virus. At termination of the study, culture and PCR examinations showed absence of A. actinomycetemcomitans, P. micros and herpesviruses, and P. nigrescens and F.nucleatum each comprised less than 0.1 % of subgingival isolates. CONCLUSION This study suggests that controlling the periodontopathic microbiota by appropriate antibiotic and conventional periodontal therapy can arrest Papillon-Lefèvre syndrome periodontitis.

Abstract
BACKGROUND Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive disorder which is characterized by palmar-plantar hyperkeratosis and rapid periodontal destruction of both primary and permanent dentitions. In this case report, we present clinical features, and microbiological and immunological findings of 40 month-old Thai male PLS patient. METHODS Microbiological examinations consisted of bacterial culture methods utilizing selective media, morphological identification, and biochemical tests. In addition, the specific serum IgG subclass antibody titers reactive with etiologic periodontal bacteria were determined by the dot-blot immunological analysis and enzyme linked immunosorbent assay (ELISA). RESULTS The examinations revealed that the patient harbored 3 major suspected periodontopathic microorganisms, A. actinomycetemcomitans, P. gingivalis, and P. intermedia. The patient's serum IgG1, IgG2, and IgG3, but not IgG4, titers against A. actinomycetemcomitans were dramatically increased. The predominant IgG subclass was IgG1. In contrast, the IgG titers against other tested bacteria, P. gingivalis, P. intermedia, and F. nucleatum, appeared to be similar to those of a healthy control. CONCLUSIONS A. actinomycetemcomitans seems to play a pivotal role in the bacteria-host interaction in PLS periodontal pathogenesis. Response of the specific serum IgG subclass antibody titers against the A. actinomycetemcomitans antigen has been demonstrated. This association warrants further investigation.

Abstract
Systemic diseases affecting the host response as primary immunodeficiencies or secondary defects caused by lack of nutrients or changes in the local tissues are very often accompanied by early-onset prepubertal periodontitis. Local treatment in combination with systemic antibiotics may in milder forms improve the situation, but in many cases the success is questionable and premature loss of teeth occurs. Since the genetic basis of many of the diseases has been identified, future developments permit the correction of at least some of these defects by gene therapy.

Abstract
AIM To analyse the microflora of subgingival plaque from patients with Papillon-Lefévre syndrome (PLS), which is a very rare disease characterised by palmar-plantar hyperkeratosis with precocious periodontal destruction. METHODS Bacterial isolates were identified using a combination of commercial identification kits, traditional laboratory tests, and gas liquid chromatography. Some isolates were also subjected to partial 16S rDNA sequencing. Plaque samples were also assayed for the presence of Porphyromonas gingivalis, Prevotella intermedia, and Actinobacillus actinomycetemcomitans in a quantitative enzyme linked immunosorbent assay (ELISA) using monoclonal antibodies. RESULTS The culture results showed that most isolates were capnophilic and facultatively anaerobic species-mainly Capnocytophaga spp and Streptococcus spp. The latter included S. constellatus, S. oralis, and S. sanguis. Other facultative bacteria belonged to the genera gemella, kingella, leuconostoc, and stomatococcus. The aerobic bacteria isolated were species of neisseria and bacillus. Anaerobic species included Prevotella intermedia, P. melaninogenica, and P. nigrescens, as well as Peptostreptococcus spp. ELISA detected P gingivalis in one patient in all sites sampled, whereas A. actinomycetemcomitans was detected in only one site from the other patient. Prevotella intermedia was present in low numbers. CONCLUSIONS Patients with PLS have a very complex subgingival flora including recognised periodontal pathogens. However, no particular periodontopathogen is invariably associated with PLS.

Abstract
BACKGROUND Papillon Lefèvre syndrome (PLS) is a rare entity and, as such, it is almost impossible to evaluate an effective therapy in a randomized controlled study. The amount of success reported after therapy for prepubertal periodontitis (PP) in PLS is highly variable from case to case. The goal of this case report is to evaluate the effects of a combined mechanical and antibiotic periodontal therapy regimen in the management of PLS. METHODS A male patient was diagnosed as suffering from PP associated with PLS at the age of 7 years. He showed hyperkeratosis of the palms and soles, as well as advanced periodontal disease already affecting permanent teeth with maximal probing depth and vertical attachment loss of 12 mm and 11 mm, respectively. Subgingival debridement was performed with simultaneous administration of oral 250 mg amoxicillin 3 times daily and 250 mg metronidazole twice daily for one week. Clinical parameters were assessed and subgingival plaque was collected from all teeth prior to therapy and 7 and 26 months after treatment. Selective cultures for A. actinomycetemcomitans were incubated for each individual tooth and DNA probe analysis was performed for various periodontal pathogens. RESULTS Prior to combined mechanical and antibiotic treatment, all teeth but one harbored Actinobacillus actinomycetemcomitans subgingivally. However, at 7 and 26 months after therapy A. actinomycetemcomitans could be detected neither by culture nor by DNA probes. Clinical parameters improved markedly and teeth erupting after therapy did not exhibit attachment loss of more than 1.5 mm during the observation period. CONCLUSIONS Eradication (suppression beneath detection levels) of A. actinomycetemcomitans seems to play a significant role in the successful treatment of localized prepubertal periodontitis in PLS.

Abstract
OBJECTIVES Papillon-Lefèvre syndrome (PLS) is a rare disease associated with prepubertal periodontitis. Our previous studies demonstrated that three unrelated patients with PLS showed the similar antigen-specific immune responses to Actinobacillus actinomycetemcomitans. The initiation of antigen-specific immune responses was involved with human leukocyte antigens (HLA) on antigen-presenting cells. The aim of this study was to examine HLA haplotypes in the three patients with PLS. SUBJECTS AND METHODS The three PLS patients, their mothers and the father of one patient participated in this study. HLA class I and class II antigens were determined serologically and DNA typing for DRB1 and DQB1 was performed using the restriction fragment length polymorphism-polymerase chain reaction method. RESULTS The distribution of serologic HLA haplotypes, in two of three patients, was found to be quite similar. The DNA typing revealed that DRB1*0406, DRB1*08032, DQB1*0302, DQB1*06011 genotypes were shared in the two patients. The probability of sharing these four DNA types in unrelated individuals was nearly 1:40,000 in the Japanese population. CONCLUSION Our results suggest that HLA antigen may be included as a possible host factor in the pathogenesis of PLS and that a genetically controlled immune response may account for an increased susceptibility to periodontal infection.

Abstract
OBJECTIVE The primary purpose of this study was to investigate the periodontal pathologic cause of Papillon-Lefèvre syndrome by comparing, with respect to neutrophil function, probands with Papillon-Lefèvre syndrome from 4 families in Egypt, unaffected siblings of the probands, and age-matched and gender-matched control subjects. STUDY DESIGN Family histories and clinical dermal and oral manifestations of Papillon-Lefèvre syndrome were evaluated for 15 affected members of 4 families with the syndrome, 10 siblings of the probands, and 7 age-matched and gender-matched controls. Phagocytic and intracellular killing (lytic activity) of polymorphonuclear neutrophils was evaluated for all subjects according to a modification of the method of Wilkinson; opsonization was evaluated according to a modification of the methods of Cutler et al. Data were analyzed by means of analysis of variance. RESULTS Family pedigrees were plotted, and consanguinity was noted in 3 of the 4 families with Papillon-Lefèvre syndrome. The means and SDs for phagocytic killing, lytic activity, and opsonization indices were as follows: probands, 4.76+/-1.99, 0.42+/-0.20, and 0.84+/-0.07; unaffected siblings, 10.4+/-1.3, 3.3+/-0.3, and 0.84+/-0.07; controls, 10.8+/-0.8, 3.5+/-0.6, and 0.85+/-0.05. The phagocytic killing and lytic activity indices demonstrated significance between the probands and both siblings and controls (P<.0005), whereas the opsonization index did not demonstrate significance between groups. CONCLUSIONS Significantly decreased neutrophil function in probands with Papillon-Lefèvre syndrome was demonstrated with respect to neutrophil phagocytotic and lytic activity but not with respect to opsonization. Therefore, specific neutrophil dysfunction appears to be etiologically involved in this disorder.

Abstract
The prevalence of 18 selected bacterial species was assessed by means of "checkerboard" DNA-DNA hybridisation in a group of 12 Saudi-Arabian adolescents with Papillon-Lefèvre syndrome. A total of 36 tooth sites were investigated. The patients exhibited severe periodontal disease with deep pockets. All 12 patients harboured the putative bacterial pathogens P. intermedia, F. nucleatum, P. micros and S. intermedius while T. denticola, B. forsythus, P. nigrescens, E. corrodens, S. noxia and C. rectus were recovered from 11 patients. P. gingivalis was recovered from 9 patients and 18 sites while corresponding figures for A. actinomycetemcomitans were 8 and 19, respectively. A number of the investigated species (B. forsythus, T. denticola, P. intermedia, C rectus) reached high levels (> or =10(6) cells) in more than 1/2 of the patients. On the other hand, bacteria such as A. actinomycetemcomitans and P. gingivalis were infrequently encountered at high levels in these subgingival samples. In conclusion, the analysis failed to demonstrate a PLS-specific profile of the subgingival infection, since the bacterial composition of the sampled sites closely resembled that characterising deep pockets in adult periodontitis patients.

Abstract
A 4-year-old child was referred, in April 1988, to Rennes Dental School (France) for deciduous tooth mobility with premature loss of 4 deciduous teeth and germs of 2 permanent incisors. Microbiological examinations by culture revealed the presence of the periodontal pathogen Actinobacillus actinomycetemcomitans. Immunofluorescence of plaque samples revealed the presence of Porphyromonas gingivalis that had not been isolated by culture. Neutrophil functions were within normal ranges. Transmission electron microscopy of gingiva showed a disorganised epithelium. The connective tissue was infiltrated by inflammatory cells. The basement membranes were normal, but the connective tissue-epithelium interface was mainly composed of short rete pegs. Scanning electron microscopy of extracted deciduous teeth revealed lack of cementum, lacunae in the cementum and lack of fibrillar insertion on the middle part of the root. Skin lesions, mainly situated on face, were observed. Treatment was by extraction of mobile deciduous teeth combined with 3-week courses of metronidazole. Clinical and microbiological follow-up was continued over a 7-year period. No periodontal lesions have been detected since eruption of the permanent teeth. The present subgingival and lingual microflora (December 1995) is composed of bacteria associated with periodontal health. However, the future appearance of a hitherto undetected systemic disease is still possible.
