Treatment of prepubertal periodontitis. A case report and discussion

Diagnosis and initial management of children presenting with premature loss of primary teeth associated with a systemic condition: A scoping review and development of clinical aid

BACKGROUND

Premature loss of primary teeth (PLPT) can be a rare presentation of systemic medical conditions. Premature loss of primary teeth may present a diagnostic dilemma to paediatric dentists.

AIMS

To identify systemic conditions associated with PLPT and develop a clinical aid.

DESIGN

OVID Medline, Embase and Web of Science were searched up to March 2023. Citation searching of review publications occurred. Exclusion occurred for conference abstracts, absence of PLPT and absence of English-language full text.

RESULTS

Seven hundred and ninety-one publications were identified via databases and 476 by citation searching of review articles. Removal of 390 duplicates occurred. Following the exclusion of 466 records on abstract review, 411 publications were sought for retrieval, of which 142 met inclusion criteria. Thirty-one systemic conditions were identified. For 19 conditions, only one publication was identified. The majority of publications, 91% (n = 129), were case reports or series. Most publications, 44% (n = 62), were related to hypophosphatasia, and 25% (n = 35) were related to Papillon-Lefèvre. Diagnostic features were synthesised, and a clinical aid was produced by an iterative consensus approach.

CONCLUSIONS

A diverse range of systemic diseases are associated with PLPT. Evidence quality, however, is low, with most diseases having a low number of supporting cases. This clinical aid supports paediatric dentists in differential diagnosis and onward referral.

The oral microbiome of a family including Papillon-Lefèvre-syndrome patients and clinically healthy members

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.

"Oral Manifestations of Patients with Inherited Defect in Phagocyte Number or Function" a systematic review

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.

Genetic mapping in papillon-lefèvre syndrome: a report of two cases

Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive heterogeneous trait which is characterized by erythematous palmoplantar hyperkeratosis, early-onset periodontitis, and associated calcification of dura mater. The etiology of PLS is multifactorial with genetic, immunological, and microbial factors playing a role in etiopathogenesis. Recently identified genetic defect in PLS has been mapped to chromosome 11q14-q21, which involves mutations of cathepsin C. This paper presents a report of 2 cases of Papillon-lefevre syndrome in which diagnosis is based on clinical presentation and genetic mapping.

Papillon-Lefèvre syndrome: Case report and review of the literature

Papillon-Lefèvre syndrome is a very rare syndrome of autosomal recessive inheritance characterized by palmar-plantar hyperkeratosis and early onset of a severe destructive periodontitis leading to premature loss of both primary and permanent dentitions. Various etiopathogenic factors are associated with the syndrome; but a recent report has suggested that the condition is linked to mutations of the cathepsin C gene. Two cases of Papillon-Lefèvre syndrome in the same family, having all of the characteristic features are presented. An 11-year-old girl, and her elder sister, a 13-year-old girl complained of loose teeth and discomfort in chewing along with recurrently swollen and friable gums. Both patients also had premature shedding of their deciduous teeth. The family history revealed consanguineous marriage of the parents. Both patients presented with persistent thickening, flaking and scaling of the skin of palms and soles. Severe generalized periodontal destruction with mobility of teeth was evident on intraoral examination; orthopantomograph examination showed severe generalized loss of alveolar bone in both the patients.

Combined Therapy in a Patient With Papillon-Lefèvre Syndrome: A 13-Year Follow-Up

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.

Periodontal treatment of patients with Papillon-Lefevre syndrome: a 3-year follow-up

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.

A microbiological study of Papillon-Lefévre syndrome in two patients

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.

Combined mechanical and antibiotic periodontal therapy in a case of Papillon-Lefèvre syndrome

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.

Subgingival microbial profile of Papillon-Lefèvre patients assessed by DNA-probes

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.

Possible autosomal-dominant inheritance of prepubertal periodontitis in an extended kindred

This study presents the clinical findings and the distribution of prepubertal periodontitis in an extended family with high prevalence of this entity. The expression of surface markers and adhesion molecules on peripheral lymphocytes were also studied. Approximately 50% of the children in this family suffered from prepubertal periodontitis. All the affected children were otherwise healthy. 2 identical twins were similarly, but not identically, affected. Detailed laboratory tests and analysis of lymphocyte surface marker expression, including CD18, were all within the normal levels. Both localized and generalized forms of prepubertal periodontitis were found. The high prevalence of prepubertal periodontitis in the 2 branches of this family, and the fact that identical twins were similarly affected, suggest a strong genetic predisposition for prepubertal periodontitis. The family pedigree is consistent with an autosomal-dominant mode of transmission. The coexistence of localized and generalized forms of the disease in sibs suggests the same genetic etiology for both entities with variability in disease expression. This variability in disease expression is further supported by the fact that 2 identical twins were not identically affected.

Genetic studies of syndromes with severe periodontitis and palmoplantar hyperkeratosis

The Papillon-Lefèvre and Haim Munk syndromes are characterized by the presence of both palmoplantar hyperkeratosis (PPK) and severe early onset periodontitis. It is the early onset periodontal disease component that distinguishes these from other more common forms of PPK. It has been proposed that the periodontal disease component may be a casual association in individuals with PPK. Genetic syndromes with palmoplantar keratosis and severe ealry onset periodontitis may be due to specific bacterial infections in individuals with PPK. Recently, keratin gene mutations have been identified in several conditions typified by palmoplantar keratosis. The present study sought to test the hypothesis that a keratin gene defect similar to those previously identified in other PPK conditions is responsible for the Haim Munk and the Papillon. Lefèvre syndromes. We have performed genetic linkage studies to test for linkage between polymorphic DNA loci within 2 cytokeratin gene families and the disease phenotype in Haim Munk syndrome and Papillon-Lefèvre syndrome. Families with individuals segregating for the Haim Munk syndrome and the Papillon-Lefèvre syndrome were examined to determine disease status, and genotyped for microsatellite DNA markers closely linked to the acidic (type I) and the basic (type II) cytokeratin genes on chromosomes 12 and 17. Genotype data were evaluated for microsatellite allele homozygosity in affected individuals. Results of these preliminary genetic studies suggest that the gene defect in Haim Munk syndrome is not due to a gene defect in either the type I or the type II keratin gene clusters. These findings suggest that Haim Munk syndrome may be genetically distinct from other more common forms of PPK that have been linked to the cytokeratin gene families, and suggest that mutations in genes other than keratin genes are responsible. Additional family studies are needed to confirm these preliminary findings.

Periodontal implications: medically compromised patients

The presence of systemic disease in patients requiring periodontal therapy creates challenges for management. Alteration of treatment plans, with emphasis on physician consultation and preventive periodontal care, is frequently needed to minimize the impact of periodontal disease on the systemic condition. Conversely, detection and treatment of systemic disorders may impact upon the status of the periodontium and the success of periodontal therapy. The goal of holistic patient management is facilitated by a free flow of information between the patients and their medical and dental health care providers.

0.1%/0.2% commercial chlorhexidine solutions as subgingival irrigants in chronic periodontitis

This study compared 2 proprietary chlorhexidine (CH) products, Corsodyl (CO-0.2% CH, then ICI, U.K.) and Eludril (EL-0.1% CH, Pierre Fabre, France) as subgingival irrigants adjunctive to Simplified Oral Hygiene. 19 subjects, 8M, 11F, aged 30-57 years, mean 44 years, took part. Probing pocket depth (PPD) ranged from 5-10 mm, mean 6.5 mm (CO and EL), with 60 CO and 65 EL sites. After oral hygiene instruction, without stress on interdental cleaning, patients received on visit supra- and subgingival debridement, and instruction in subgingival irrigation using the Max-I-Probe system (Smith & Nephew MPL, USA). For baseline, days 28 (end of irrigation), 56 and 84, data were respectively: GI (medians): 1.7, 1.2, 1.2, 1.0 (CO), 1.9, 1.5, 1.3, 1.0 EL); BOP (medians): 1.2, 0.4, 0.7, 0.4 (CO), 1.5, 0.6, 0.6, 0.25 (EL); PPD (mm) (means): 6.3, 4.8, 4.2, 4.5 (CO), 6.8, 5.2, 5.3, 4.7 (EL); PAL (mm) (means-change relative to day 0): 0.6, 0.5, 0.8 (CO), 0.8, 0.8, 1.5 (EL). By Wilcoxon for non-parametric and t-tests for parametric data, both groups showed significant improvement for all variables at all times relative to baseline, with only one significant difference between the groups, in favour of EL, for PAL at day 84 (p < 0.05). This pilot study indicates that both simplified oral hygiene regimes are effective in periodontitis, but that there was no difference between the 2 commercial irrigants as adjunctives.

Clinical, bacteriological, and immunological examinations and the treatment process of two Papillon-Lefèvre syndrome patients

Papillon-Lefèvre Syndrome (PLS) is a rare disease associated with the early onset of periodontal breakdown in deciduous and permanent dentition. The etiology of the destruction has not been completely clarified. Two female patients (ages 4 and 7 years) with severe destruction of the periodontal structures were examined. Except for palmar and plantar hyperkeratosis, dermatologic examination revealed no other medical disorders. On immunological analysis, measurement of serum antibody titers to 7 periodontopathic bacteria including Porphyromonas gingivalis and Actinobacillus actinomycetemcomitans was performed by enzyme-linked immunosorbent assay (ELISA). Further immunoblot analysis of A. actinomycetemcomitans and microbial culture of samples collected from deep periodontal pockets and mouthrinse solution were performed. The serum of the two patients showed high IgG titer against A. actinomycetemcomitans. Immunoblot results of the two patients against sonicated extract of A. actinomycetemcomitans Y4 strain exhibited a similar pattern. The band pattern differed from that observed in other forms of early onset periodontitis patients or periodontally healthy subjects. Moreover, A. actinomycetemcomitans colonies were cultured in high percentages from the pocket samples. Antibiotic therapy was instituted in addition to conventional periodontal therapy. In the younger patient, all deciduous teeth were extracted as part of the treatment and A. actinomycetemcomitans was no longer detected. All four permanent first molars and 8 permanent incisors subsequently erupted with healthy periodontium. However, the older patient did not improve after periodontal and antibiotic (minocycline and erythromycin) treatments and A. actinomycetemcomitans was consistently detected. Ofloxacin medication finally eliminated A. actinomycetemcomitans from the periodontal pockets. This antibiotic was also associated with reduced gingival inflammation and probing depth.(ABSTRACT TRUNCATED AT 250 WORDS)
