Generalized aggressive periodontitis in a prepubertal patient: a case report.

A 10-year-old boy presented with generalized gingival inflammation, extensive alveolar bone loss, and tooth mobility. Clinical and radiographic examination supplemented by microbiologic investigation led to a diagnosis of classically termed prepubertal periodontitis (now known as generalized aggressive periodontitis). Other than severe periodontitis, the child was systemically healthy. Neither unusual infections nor abnormalities in neutrophil functions were detected. Microbiologic examinations by culture revealed the presence of the periodontal pathogen Actinobacillus actinomycetemcomitans. Treatment consisted of extraction of mobile teeth, supragingival and subgingival debridement, subgingival curettage, and root planing combined with a 1-week prescription of a combination of metronidazole and amoxicillin. Scanning electron microscopy of extracted teeth revealed hypoplastic and aplastic cementum at the periodontally exposed and intact surfaces. Clinical and microbiologic follow-up was continued over a 1-year period. No periodontal lesions have been detected, and A actinomycetemcomitans could not be isolated from the subgingival areas of the remaining teeth at the end of the first year. Since A actinomycetemcomitans was the main pathogen present in the subgingival microflora of the patient, it might play a key role in the etiology of prepubertal periodontitis.

The effect of systemic ibuprofen on gingival inflammation in humans.

This clinical trial investigated the influence of short-term ibuprofen therapy on the early phase of the treatment of adult chronic periodontitis. The subjects were 17 patients in good general health referred for specialist periodontal treatment, having moderate chronic adult periodontitis. A series of assessments were made every 2 weeks over an 8-week period, including evaluations of oral hygiene, gingival inflammation and probing pocket depths. All participants received oral hygiene instruction, and following baseline examinations, had half the dentition, chosen at random, treated by scaling and root planing. The patients were randomly distributed into 2 groups, a test group receiving a 14-day course of 800 mg ibuprofen daily, in 4 divided doses, and a control group who did not receive any drug regime. At the 2-week assessment following the drug regime, significantly greater reduction in gingival bleeding, colour and pocketing was detected in the test compared with the control group. The beneficial effects were less evident thereafter. Although clinical application of the regime used in this study would not be justified by these results, further research into anti-inflammatory agents as an adjunct in the treatment of periodontal diseases could be considered, in the light of the beneficial effect on gingivitis in the early phase of periodontal treatment reported.

Effective periodontal treatment in a patient with type IIA von Willebrand's disease: report of a case.

von Willebrand's disease (vWD) is one of the most common hereditary hemorrhagic disorders. A mild to moderate deficiency of factor VIII and von Willebrand factor (vWf) often is associated with gingival bleeding. In this case report, the periodontal treatment of a patient with vWD is described. A 45-year-old woman with type IIA vWD was referred for periodontal therapy because of an episode of gingival hemorrhage and percussion pain of teeth #18 and #47. The periodontal findings included probing depths ranging from 2 to 6 mm, horizontal bone loss, and Class II furcation involvement of tooth #46. After consultation with a hematologist, apically positioned flap surgery and hemisection were performed on tooth #46 following completion of oral hygiene instruction, scaling and root planing, and endodontic therapy. The patient was given 500 units of factor VIII including vWf multimer 30 minutes before surgery. After healing of the periodontal tissue, prosthodontic treatment was undertaken on the posterior mandibular sextants. At follow-up, the probing depths ranged from 2 to 3 mm, and gingival bleeding on probing was minimal. The patient's children all had vWD. They had mild to moderate periodontitis with probing depths ranging from 2 to 5 mm and gingival bleeding on probing. With the combined efforts of the periodontist and hematologist, effective periodontal treatment can be provided to patients with von Willebrand's disease.

Clinical outcome observed in subjects with recurrent periodontal disease following local treatment with 25% metronidazole gel.

BACKGROUND: The aim of this study was to evaluate the clinical outcome in patients with recurrent periodontal disease following treatment with 25% metronidazole gel. METHODS: Twenty subjects in a maintenance care program but with recurrent periodontal disease participated. Three months after scaling and root planing, a total of 40 sites, 2 in each patient, with probing depth > or = 5 mm were selected. One site randomly selected was treated with metronidazole gel (test) and the other site with a placebo gel (control). Baseline and follow-up measurements included plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL). RESULTS: There were no statistically significant differences in PI, GI, BOP, PD, or CAL between test and control sites. CONCLUSION: This study showed that local treatment with 25% metronidazole gel did not seem to influence the clinical healing in this group of subjects with recurrent periodontal disease.

Longitudinal periodontal treatment outcomes in private practice.

The majority of studies evaluating the efficacy of periodontal therapy have been conducted in university-based clinical trials under ideal and well-controlled conditions, where time (and cost) effectiveness was not an overriding factor. In Australia, where the larger proportion of dental treatment is provided by the private sector, there are no clinical studies which provide information on the efficacy of periodontal treatment in general or specialist private practice. The overall purpose of this study was to evaluate the efficacy of periodontal therapy in a specialist private practice over an initial period of 5.3 years in a group of 100 patients, and subsequently on the remaining 70 patients followed over a period 13.5 years. Hence the total observation period extended over nearly two decades. Using frequency distributions of site data, and statistical inferences based on the patient as the experimental unit, the results indicated an overall improvement and subsequent stability in clinical attachment in all categories of Initial Probing Depths, for both single- and multi-rooted teeth, for teeth treated with root planing alone and those that required adjunctive surgical intervention, and for younger and older patients. It was also noted that very few teeth were lost over the extended observation period. These positive results were achieved in a most favourable time in the initial phase of treatment (1.5-2.0 hours) as compared with the protracted time frame (5-8 hours) recorded in university-based clinical trials. Similarly, professional maintenance therapy took an average of around two appointments per year (1 hour) compared with an average of 3-4 hours per year in the university-based studies. The results therefore proved not only satisfactory from the standpoint of clinical parameters measured but also on the basis of time efficiency.

[Clinical study of hyaluronic acid in the treatment of chronic periodontitis].

OBJECTIVE: Clinical effects in local application of hyaluronic acid (HA) adjunctive to scaling and root planing (SRP) were evaluated. METHODS: In this cross over design study 20 patients with chronic periodontitis were included. Plaque index, sulcus-fluid-flow-rate (SFFR), sulcus bleeding index, probing pocket depth and attachment level were monitored. All patients were treated with full mouth SRP, in addition a HA gel was administered subgingivally in the test site every week for 6 weeks. RESULTS: A statistically significant improvement of all clinical test parameters was observed in both groups (P < 0.05). Clinically, no significant difference between test and control group could be found. However, the SFFR decreased significantly faster in the test group. CONCLUSION: No post-inflammatory tissue regeneration could be achieved by the adjunctive use of HA gel to SRP in the patients with chronic periodontitis. Due to SFFR a control of local inflammation can be achieved quickly.

Evaluation of periodontal regeneration following grafting intrabony defects with bio-oss collagen: a human histologic report.

This study evaluated the clinical, radiographic, and histologic response to Bio-Oss Collagen when used alone or in combination with Bio-Gide bilayer collagen membrane for the treatment of four intrabony defects (5 to 7 mm) around single-rooted teeth. After reflecting a full-thickness flap, thorough degranulation and root planing were accomplished. In all cases, Bio-Oss Collagen was then used to fill the defects, and in two cases, a Bio-Gide membrane was placed over the filled defect. Radiographs, clinical probing depths, and attachment levels were obtained before treatment and immediately preceding en bloc resection of teeth and surrounding tissues 9 months later. Reduction in pocket depth and gain in clinical attachment level were observed for both treatment protocols. The histologic evaluation demonstrated the formation of a complete new attachment apparatus, evidencing periodontal regeneration that varied with defect morphology. This human histologic study demonstrated that Bio-Oss Collagen has the capacity to induce regeneration of the periodontal attachment apparatus when placed in intrabony defects.

Depth-force patterns of periodontal probing. Attachment-gain in relation to probing force.

It was the purpose of this study to determine whether probing force had an influence on the amount of clinical attachment-gain assessed after treatment by scaling and rootplaning. A probing device was constructed which allowed simultaneous monitoring of probing force and probe penetration and which standardized the insertion pathway for repeated measurements. In 10 periodontal patients, 2 deep pockets were selected which were measured before and after periodontal treatment by scaling and root-planing. Depth-force plots were compared by superimposition. Depth values were determined at 5 different force levels (0.25, 0.50, 0.75, 1.00 and 1.25 N) on each plot and changes of clinical attachment levels were calculated. A significant relationship was seen between probing force and attachment level. The values obtained with 0.25 N were significantly different from the values obtained with higher forces (p less than 0.001). Slight, but non-significant differences were noted in the amount of attachment-gain obtained at the 5 force levels. At a probing force level of 0.25 N, there was 0.80 mm mean attachment gain. With 0.50 N, there was a gain of 0.70 mm; with 0.75 N the gain amounted to 0.67 mm in mean. At 1.00 N and at 1.25 N, a gain of 0.66 mm was recorded.

A placebo-controlled multi-centred evaluation of an anaesthetic gel (Oraqix) for periodontal therapy.

AIMS: Six Canadian dental schools investigated the ability of a thermosetting gel containing 25 mg/g prilocaine and 25 mg/g lidocaine as active agents to produce analgesia in periodontal pockets utilizing a randomized, double-blind, placebo-controlled study. MATERIALS AND METHODS: The study consisted of 130 patients, each of whom received the active or placebo gel in periodontal pockets in one quadrant of the mouth for 30 s prior to periodontal debridement (scaling and root planing). Pain was measured using both a 100-mm Visual Analogue Scale (VAS) and a Verbal Rating Scale (VRS). RESULTS: The median VAS pain score for the patients treated with the anaesthetic gel was 5 mm (range 0-85 mm) as opposed to 13 mm (range 0-79 mm) in the placebo-treated patients (P=0.015). There was no significant difference in the percentage of patients reporting no or mild pain (78% and 76% for the anaesthetic gel and placebo, respectively). No significant differences were seen in patient demographics, or mandible versus maxilla. CONCLUSIONS: The VAS pain scores showed that the anaesthetic gel 5% was statistically more effective than the placebo in reducing pain during periodontal debridement.

A randomized trial of occlusal adjustment in the treatment of periodontitis patients.

The purpose of the randomized clinical trial was to test; (1) the influence of occlusal adjustment (OA) in association with periodontal therapy on attachment levels, pocket depth, and tooth mobility, (2) whether OA was of greater significance in non-surgically treated periodontal defects, and (3) whether initial tooth mobility or disease severity had an affect on post-treatment attachment levels following OA. After hygienic-phase therapy, 50 patients received OA/No OA according to random assignment; 22 patients received an OA and 28 were not adjusted. 2 months after OA, either modified Widman flap surgery or scaling and root planing by a periodontist were done according to random assignment within each patient in a split-mouth design. Following active treatment patients were maintained with prophylaxis done every 3 months and scored annually. For the analysis of this two-year data, a repeated measures analysis of variance was performed using attachment level change and pocket depths as outcome indicators. There was significantly greater gain of clinical periodontal attachment in patients who received an OA compared to those who did not. Both the surgically and non-surgically treated sides of the mouth responded similarly to OA. There was no affect of OA on the response in pocket depth, nor did initial tooth mobility or initial periodontal disease severity influence the response to OA.

Patient preference regarding 4 types of periodontal therapy following 3 years of maintenance follow-up.

It has been shown that certain types of periodontal therapy result in greater post-therapy gingival recession. It has been suggested that this recession may lead to maintenance complications for patients. This study evaluated patient perceptions 3 years following the completion of 4 types of periodontal therapy (coronal scaling (CS), root planing (RP), modified Widman surgery (MW), and flap with osseous resectional surgery (FO)). 75 individuals completed split-mouth therapy and 3 years of maintenance follow-up. An interview survey of all patients categorized their perception for each treatment of their mouth concerning difficulty in cleaning, sensitivity to temperature, general "feeling" of the region, prevalence of localized symptoms, food retention, comfort of oral examination, and attitude toward repeating therapy. Responses to questions showed no statistically significant differences between treatment regions. Patterns demonstrated that FO-treated regions were perceived to have less food retention, but were more difficult to clean. It was generally found that at the end of 3 years of maintenance, patients felt their mouths were "normal", they experienced few localized symptoms, and were very willing to repeat any of the treatment regimens if necessary.

The effect of systemic antibiotics in the treatment of patients with recurrent periodontitis.

BACKGROUND: Subjects with periodontal disease exist who either (i) respond poorly to initial mechanical therapy ("refractory" periodontitis) or (ii) fail to adopt adequate self-performed plaque control techniques and hence develop recurrent disease ("recurrent" periodontitis) at multiple sites during the supportive treatment phase (SPT). Various systemic antibiotic regimens have been tried as adjuncts to the mechanical (re-) treatment of such "difficult to treat"-patients. While most studies indicated a positive outcome of the adjunctive therapy, some clinical investigators reported that this additional measure provided little or no benefit. AIM: The aim of the present investigation was to study the more long term effect of adjunctive antibiotic therapy in the re-treatment of patients with a well defined history of recurrent periodontitis. MATERIAL AND METHODS: 17 subjects with recurrent advanced periodontal disease were, following a baseline examination, subjected to non-surgical therapy including the use of systemic antibiotics (amoxicillin and metronidazole). They were placed in a careful SPT program and re-examined after 1, 3 and 5 years. The examinations included both clinical and microbiological assessments. RESULTS: It was demonstrated that in subjects with advanced and recurrent periodontitis, re-treatment including (i) comprehensive scaling and root planing (SRP), (ii) systemic administration of antibiotics and (iii) meticulous supragingival plaque control by both mechanical and chemical means established periodontal conditions that in the short term (3 years) and in the majority of subjects could be properly maintained by traditional SPT measures. Between 3 and 5 years, however, only 5 of the 17 subjects exhibited stable periodontal attachment levels. CONCLUSIONS: Some deep pockets and furcations were most likely inadequately instrumented during the active treatment phase. Microorganisms residing in biofilms left in such locations were probably not sufficiently affected by the 2 weeks of adjunctive antibiotic therapy. It is suggested that removal of certain subgingival deposits, therefore, may require surgical intervention.

The effectiveness of video support in the teaching of manual skills related to initial periodontal therapy tested on phantoms.

INTRODUCTION: The teaching of manual skills and competencies is among the most time-consuming aspects of oral health-care education, especially when large groups of students are involved. Video has been repeatedly used as an educational tool with varying results. PURPOSE: The present study aimed to investigate the effectiveness of a computer-based video support system during practical training of manual skills and competencies related to periodontal treatment. MATERIALS AND METHODS: Eighty-four students were randomized into 9 groups: 5 experimental and 4 control groups. The control groups received instruction in the use of scaling and root planing instruments during a 7-hour seminar, and 2 hours of manual practice. The experimental groups received the same instruction, but in addition had access to a computer-based video support system, the Visual Training System (VTS), during practical training. During the 2-hour long practice session, all students practiced 21 different procedures, which were video recorded. The videos were later evaluated by an independent observer. RESULTS: On the whole, the students in the experimental group performed significantly better than their colleagues in the control group. Specifically, the groups that utilized the VTS video support performed significantly better in 9 of the 21 procedures tested. CONCLUSION: These results suggest that this computer-based video support can be an effective aid in the teaching of manual skills related to oral health care.

Effect of an oily calcium hydroxide suspension on early wound healing after nonsurgical periodontal therapy.

The purpose of the present study was to evaluate clinically the effect of an oily calcium hydroxide suspension on early wound healing after nonsurgical periodontal therapy. A total of 19 patients with chronic periodontitis were enrolled in the study. Each subject had three sites in each of two contra-lateral jaw quadrants with a probing pocket depth (PPD) of > or =5 mm and bleeding on probing (BoP+). All teeth received scaling and root planing under local anesthesia followed by irrigation with sterile saline. An oily calcium hydroxide suspension (Osteoinductal) was applied subgingivally to the test sites at random. All sites were reexamined after 1, 2 [gingival index (GI) and BoP], and 3 weeks (GI, BoP, and PPD). Treatment success was defined as no signs of GI (GI=0), no BoP (BoP-), and pocket closure (PPD< or =4 mm). At all three different points in time, there were improvements in both GI and BoP at the control and test sites, which were in favor of the test therapy (p<0.05). For PPD change, no differences were found between the test and the control sites. The results of the study suggest that the topical application of an oily calcium hydroxide suspension (Osteoinductal), after nonsurgical periodontal therapy, improves early periodontal wound healing.

Subgingival microflora and treatment in prepubertal periodontitis associated with chronic idiopathic neutropenia.

Prepubertal periodontitis affects both primary and permanent dentition. The purpose of this study was to examine the composition of subgingival microflora of the permanent dentition in an 11-year-old Caucasian female, who had premature exfoliation of her deciduous teeth on her 5th year of age, and the response of this condition to the antibiotic therapy and supportive periodontal care. Gingival tissues were highly inflamed and alveolar bone loss was detected radiographically. The girl had experienced frequent upper respiratory tract infections, tonsilitis and recurrent otitis media. Her mother had history of early onset periodontitis associated with chronic idiopathic neutropenia. Blood chemistry tests and immunological examinations were also performed. Subgingival plaque samples were collected from the proximal sites of permanent molars, incisors, canines and maxillary premolars. 27 different microbial species were isolated from the subgingival microflora. Among the predominant species were Porphyromonas gingivalis (17.6%-7.3%), Prevotella intermedia (12.4%-4.7%), Capnocytophaga sputigena (14.4%-10.4%), Capnocytophaga ochracea (13.2%-6.9%) and Actinobacillus actinomycetemcomitans (9.3%-5.5%). Periodontal treatment consisted of scaling, root planing in conjunction with antibiotic administration of Augmentin 312.5 mg and Flagyl 200 mg, each t.i.d. for 10 days. 3 weeks after the antibiotic therapy, bacterial samples were collected from the same sites. All the periodontal pathogens were recovered in lower levels and A.actinomycetemcomitans was almost eliminated in the 3-week period. The evaluation of clinical indices at 3, 6 and 12 months showed that periodontal treatment in conjunction with antibiotics was effective and rapidly followed by marked clinical improvement. The microbiological monitoring at 3, 6 and 12 months after antibiotic treatment and each time prior to supportive periodontal care, revealed that the periodontal pathogens fluctuated in low levels even 12 months after treatment and could be maintained at low level by supportive periodontal care at 3-month intervals.

Relationship between periodontal probing velocity and gingival inflammation in human subjects.

Little is known about the biophysical characteristics of the dentogingival junction in response to the development or resolution of inflammation. The Toronto Automated Periodontal Probe (TAPP) provides an estimate of the integrity of the dentogingival junction by measuring intrapocket probing velocity. The aim of this study was to measure changes of probing velocity in inflamed human periodontium before and after subgingival debridement. 32 subjects exhibiting gingival inflammation were selected; 29 completed the study. Gingival index (GI), plaque index (PLI), bleeding index (BI) and the rate of gingival crevicular fluid flow (CFF) were measured as concomitant variables. The experimental group (N = 16) received scaling, root planing and oral hygiene instruction at baseline. The control group (N = 13) received no treatment until after 28 days. Subjects were seen at baseline, day 14, 21 and 28 for measurement of probing velocity and concomitant variables on 6 index teeth. At day 28, the control group was treated and then reassessed 28 days later. The experimental group showed a reduction of 51.6% for mean crevicular fluid flow (p < 0.0001), 79.7% for mean plaque index (p < 0.0001), 58.0% for mean gingival index (p < 0.0001), and 72.0% for mean bleeding index (p < 0.01) at day 28, confirming that inflammation was reduced compared with baseline. No significant changes were observed in the control group until after treatment. The velocity of probing and the formation of a plateau in the velocity profile were recorded.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical, genetic, and biochemical findings in two siblings with Papillon-Lefèvre Syndrome.

BACKGROUND: Papillon-Lefèvre Syndrome (PLS) is an autosomal recessive disease characterized by palmoplantar hyperkeratosis and severe periodontitis affecting both primary and secondary dentitions. Cathepsin C (CTSC) gene mutations are etiologic for PLS. The resultant loss of CTSC function is responsible for the severe periodontal destruction seen clinically. METHODS: A 4-year-old female (case 1) and her 10-year-old sister (case 2) presented with palmoplantar skin lesions, tooth mobility, and advanced periodontitis. Based on clinical findings, the cases were diagnosed with PLS. Mutational screening of the CTSC gene was conducted for the cases, and their clinically unaffected parents and brother. Biochemical analysis was performed for CTSC, cathepsin G (CTSG), and elastase activity in neutrophils for all members of the nuclear family. The initial treatment included oral hygiene instruction, scaling and root planing, and systemic amoxicillin-metronidazole therapy. RESULTS: CTSC mutational screening identified a c.415G>A transition mutation. In the homozygous state, this mutation was associated with an almost complete loss of activity of CTSC, CTSG, and elastase. Although monthly visits, including scaling, polishing, and 0.2% chlorhexidine digluconate irrigation were performed to stabilize the periodontal condition, case 1 lost all her primary teeth. In case 2, some of the permanent teeth could be maintained. CONCLUSIONS: This report describes two siblings with a cathepsin C gene mutation that is associated with the inactivity of cathepsin C and several neutrophil serine proteases. The failure of patients to respond to periodontal treatment is discussed in the context of these biological findings.

Papillon-Lefèvre syndrome: a successful outcome.

BACKGROUND: Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive condition manifested clinically by hyperkeratosis of the palms and soles and rapidly progressive periodontitis resulting in loss of deciduous and permanent teeth. This case report describes the clinical periodontal findings and treatment of a 10-year-old male patient with PLS. The patient provided informed consent, and the study was conducted in accordance with the Helsinki Declaration of 1975, as revised in 2000. METHODS: Upon initial presentation, a full periodontal examination was completed. Conventional probing depths, clinical attachment levels (CAL), gingival index (GI), and plaque index (PI) were measured prior to initial therapy, which involved oral hygiene instruction and scaling and root planing. At reevaluation, initial treatment proved unsuccessful, and a surgical approach with concomitant systemic antibiotic therapy was implemented. In addition, the patient's dermatologist treated his palmoplantar keratoderma with systemic retinoids. Subsequently, the patient was placed on a strict 3-month maintenance protocol and was evaluated over a period of 1 year. RESULTS: Initial treatment with mechanical therapy, oral hygiene instruction, frequent recalls, and systemic antibiotics did not yield efficacious results. However, with the addition of surgical treatment, a favorable clinical outcome was obtained. CONCLUSIONS: Numerous treatment regimens for the periodontal disease seen in PLS can be found in the literature. We demonstrate successful treatment of the periodontal disease seen in this condition using mechanical therapy, systemic antibiotics, and surgical modalities; over a period of 1 year, we were able to achieve significant reductions in gingival inflammation and erythema.
