[The association between maternal periodontal health and adverse pregnancy outcomes]. / A várandós no parodontalis egészségi állapota és a terhességi komplikációk közötti kapcsolat.

Data from epidemiological and clinical studies published in the past two decades indicate certain association between periodontal disease and increased risk for preterm birth or low birth weight. Although the strength of those observed associations is weak, periodontitis today is considered as one of the potentially modifiable risk factors for adverse pregnancy outcomes. The aims of the publication are to summarize the epidemiological and clinical evidence for the impact of periodontal disease on adverse pregnancy outcomes and to make an attempt to overview the potential biological mechanism behind this association. The majority of epidemiological and clinical studies found certain negative effect of poor maternal periodontal condition on the incidence of low birth weight, preterm birth, pre-eclampsy, restricted foetal growth or even stillbirth. Two possible biological pathways have so far been identified: 1) the direct dissemination of the periodontal pathogens or their toxic by-products which reach the foetal-placental unit, and 2) an indirect mechanism when the circulating systemic inflammatory mediators induced by the periodontal inflammation can provoke secondary inflammation and foetal damage in the amnion. The periodontal therapy applied during the second or third trimesters has not been proven to reduce the incidence of any adverse pregnancy outcomes in pregnant women. A much more prophylaxis-oriented approach in periodontal treatment is needed. The adequate periodontal therapy should be completed before the conception to provide benefit to the pregnant women and also the new born baby. Orv Hetil. 2018; 159(25): 999-1007.

[The significance of biotype in the predictability of dental-periodontal treatment]. / Biotípus jelentosége a fogászati-parodontélis kezelések kiszámíthatóságában. Irodalmi összefoglaló és keresztmetszeti vizsgálat.

BACKGROUND: The dimension of attached gingiva is a very important landmark in the periodontal health, and determine the function of the mucogingival unit, the progression of marginal inflammation and also affects aesthetic dentistry, orthodontics and implantology. The determination of gingival/periodontal biotype is important in dental/periodontal practice. Hence, the aim of this cross sectional clinical study was to assess the width and thickness of attached gingiva in young, periodontally healthy individuals and to provide anthropometric data in Hungary. MATERIALS AND METHODS: 68 periodontally healthy (between the age of 14-28) individuals participated in the study. The thickness of the gingiva was determined using transgingival transparency of periodontal probe at each tooth in the maxillary and mandibular dental arch. Based on this non-invasive technique three biotype categories were determined i.e. thin > 1 mm, medium 1-2 mm and thick < 2 mm. The width of the gingiva was assessed by William's graduated probe measuring the distance between the gingival margin and mucogingival line the midline of each tooth. The data were statistically analyzed and compared according to gender, dental arch and group of teeth. RESULTS: The gingiva was found to be thinner in females than males. The thin biotype was significantly more common among females while in males the thick biotype was the dominant. The individual variations were common within dental arch and many times the biotype switched from tooth to tooth. The average width of the attached gingiva was wider in the maxilla than in the mandible and there was no statistically significant correlation between the biotype and the width of attached gingiva. Manifest gingival recession occurred just around teeth with thin biotype. CONCLUSION: In the present study, we concluded that gingival thickness and width varies with gender and dental arch location and the biotype had no effect on the width of attached gingiva.

[Evaluation of the efficacy of powered and manual toothbrushes in preventing oral diseases (Systematic review with meta-analysis)]. / Elektromos és kézi fogkefék hatékonyságának összehasonlítása az orális prevencióban. Irodalmi áttekintés, systematic review, meta-analízis.

BACKGROUND: The removal of dental plaque plays an essential role in the maintenance of oral health. Numerous powered and manual toothbrushes were manufactured to achieve this goal, but even up to this day different opinions and research results have been revealed to assess the priority of the mentioned devices. AIM: Comparison of powered and manual toothbrushes on the basis of periodontal parameters and safety. MATERIALS AND METHODS: Electronic search of the databases of MEDLINE and EMBASE (until May 2014) was carried out with the help of keywords in order to find relevant trials. The inclusion criteria were as follows: randomised controlled clinical trials, adult population, the presence of at least 15 permanent teeth. Split-mouth trials and interventions carried out by dental professionals, were excluded. Primary outcomes were the changes of plaque and gingival indices, while secondary outcomes were probing pocket depth (PPD), safety and quality assessment. The effect-size of the interventions was expressed by the standardised mean difference (SMD) with 95% confidence interval (CI). Random-effects models were performed. RESULTS: Electronic search resulted in 173 hits. 21 trials with the total number of 1500 subjects were then eligible for the meta-analysis. Both toothbrushes were safe, without considerable side effects on soft or hard tissues. Powered toothbrushes seemed to be generally more effective in removing plaque (-9%), reducing gingivitis (-6%) and preventing calculus formation. The SMDs for plaque and gingival indices were -0,40 (95% Cl: -0,95 to -0,16) and -0,29 (95% Cl: -0,56 to -0,03) respectively, in favour of the powered devices. There was no significant difference in changes of PPD. By further dividing the powered toothbrushes according to their mode of action, the plaque removal effect of the rotation oscillation (plus three dimensional), side to side sonic and ultrasonic toothbrushes seemed to be significantly better, than their manual ones, while the counter oscillation and the ionic toothbrushes did not perform better. Quality assessment and sensitivity analysis revealed various types of bias up to a certain extent. Consequently, no trial was found to be eligible for the highest quality criteria. CONCLUSIONS: The investigated rotation oscillation and vibrating toothbrushes appeared to be statistically more effective than their manual counterparts, although there is little known about its clinical relevance. The advantage of the electric toothbrushes disappears in case of adequately instructed and motivated patients that highlights the importance of individualised oral hygiene education. The design of the trials shows high heterogeneity, therefore their clinical implications should be handled carefully.

[Treatment of localized intrabony periodontal defects with enamel matrix derivative (Emdogain). Case series]. / Lokalizált parodontális csontdefektusok regeneratív kezelése zománc mátrix proteinnel (Emdogain). Esetsorozat.

The solitary vertical or horisonto-vertical bone lesions are mainly characteristic of aggressive periodontitis. Only a combined conservative-surgical approach can result in predictable healing. From the early 50's basically two surgical techniques were used for correcting vertical bony defects. The so called bone resective techniques combined with apically positioned flap resulted in the flattening of the bone contour by removing substantial amount of alveolar bone but compromising the periodontal support of the neighboring teeth. The other surgical approach was the facilitation of the reformation of new periodontal attachment and bone with or without bone grafting. Since the mid 80's the gold standard in the therapy of deep vertical bony defects is the guided tissue regeneration (GTR), although an alternative approach has also been developed using different growth and differentiation factors promoting periodontal wound healing. Today in the clinical practices both in periodontal osseous and mucogingival surgeries the most widely used biological factor is the amelogenin and its commercially available product the Enamel Matrix Derivative (Emdogain). With the presented five solitary horisonto-vertical bony defects of three patients the possibilities and the late results are presented that could have been achieved with the application of EMD and thorough postoperative follow-up. The clinical results were comparable to the current data presented by articles in peer reviewed periodontal journals.

[Clinical examination of the gingival effects of three glass ionomer restorative materials (GC Fuji IX GP, GC Fuji IX GP EXTRA és GC EQUIA)]. / GC Fuji IX GP, GC Fuji IX GP EXTRA és GC EQUIA üvegionomer tömoanyagok gingiva állapotára gyakorolt hatásának vizsgálata.

The restoration of cervical abrasions, erosions or cervical carious lesions is still challenging because of their unpredictable adhesion and possible negative effects on the marginal plaque accumulation. The impact of three different glass ionomer cements (GIC) on the marginal gingiva and root sensitivity was studied. Furthermore, it was investigated in details, whether or not a recently developed light curing varnish (GC Coat - EQUIA) had any additional effect on the gingival tissue. A total number of 30 non-smokers with healthy gingiva having at least one cervical supra/paragingival abrasion/erosion/abfraction defects were enrolled in the present study. The cervical defects were randomly restored by using one of the three GIC and the gingival parameters were recorded and evaluated at baseline, 6 weeks and 6 months. According to our results root sensitivity were substantially decreased in all the three groups. Plaque scores were also reduced in all groups with the greatest improvement at the sites where the new varnish were applied. Although this improvement was not reflected by the gingival parameters, such as bleeding on probing and crevicular fluid flow, since both were slightly increased in the varnish group. However, neither the intra-group, nor the intergroup differences reached statistical significance. Consequently, the three investigated GIC did not significantly affect the gingival health, therefore they might serve as alternative for the treatment of such cervical lesions. Nevertheless, the new light cure varnish-coated GIC did not seem to be either clinically or statistical significantly more favorable.

Treatment of multiple adjacent Miller class I and II gingival recessions with a Modified Coronally Advanced Tunnel (MCAT) technique and a collagen matrix or palatal connective tissue graft: a randomized, controlled clinical trial.

BACKGROUND: A newly developed collagen matrix (CM) of porcine origin has been shown to represent a potential alternative to palatal connective tissue grafts (CTG) for the treatment of single Miller Class I and II gingival recessions when used in conjunction with a coronally advanced flap (CAF). However, at present it remains unknown to what extent CM may represent a valuable alternative to CTG in the treatment of Miller Class I and II multiple adjacent gingival recessions (MAGR). The aim of this study was to compare the clinical outcomes following treatment of Miller Class I and II MAGR using the modified coronally advanced tunnel technique (MCAT) in conjunction with either CM or CTG. METHODS: Twenty-two patients with a total of 156 Miller Class I and II gingival recessions were included in this study. Recessions were randomly treated according to a split-mouth design by means of MCAT + CM (test) or MCAT + CTG (control). The following measurements were recorded at baseline (i.e. prior to surgery) and at 12 months: Gingival Recession Depth (GRD), Probing Pocket Depth (PD), Clinical Attachment Level (CAL), Keratinized Tissue Width (KTW), Gingival Recession Width (GRW) and Gingival Thickness (GT). GT was measured 3-mm apical to the gingival margin. Patient acceptance was recorded using a Visual Analogue Scale (VAS). The primary outcome variable was Complete Root Coverage (CRC), secondary outcomes were Mean Root Coverage (MRC), change in KTW, GT, patient acceptance and duration of surgery. RESULTS: Healing was uneventful in both groups. No adverse reactions at any of the sites were observed. At 12 months, both treatments resulted in statistically significant improvements of CRC, MRC, KTW and GT compared with baseline (p < 0.05). CRC was found at 42% of test sites and at 85% of control sites respectively (p < 0.05). MRC measured 71 ± 21% mm at test sites versus 90 ± 18% mm at control sites (p < 0.05). Mean KTW measured 2.4 ± 0.7 mm at test sites versus 2.7 ± 0.8 mm at control sites (p > 0.05). At test sites, GT values changed from 0.8 ± 0.2 to 1.0 ± 0.3 mm, and at control sites from 0.8 ± 0.3 to 1.3 ± 0.4 mm (p < 0.05). Duration of surgery and patient morbidity was statistically significantly lower in the test compared with the control group respectively (p < 0.05). CONCLUSIONS: The present findings indicate that the use of CM may represent an alternative to CTG by reducing surgical time and patient morbidity, but yielded lower CRC than CTG in the treatment of Miller Class I and II MAGR when used in conjunction with MCAT.

Histological evaluation of human intrabony periodontal defects treated with an unsintered nanocrystalline hydroxyapatite paste.

OBJECTIVES: The aim of the study was to clinically and histologically evaluate the healing of human intrabony defects treated with open flap surgery (OFD) and application of a new, resorbable, fully synthetic, unsintered, nanocrystalline, phase-pure hydroxyapatite (nano-HA). MATERIALS AND METHODS: Six patients, each of them displaying very advanced intrabony defects around teeth scheduled for extraction due to advanced chronic periodontitis and further prosthodontic considerations, were included in the study. Following local anaesthesia, mucoperiosteal flaps were reflected; the granulation tissue was removed, and the roots were meticulously debrided by hand and ultrasonic instruments. A notch was placed at the most apical extent of the calculus present on the root surface or at the most apical part of the defect (if no calculus was present) in order to serve as a reference for the histological evaluation. Following defect fill with nano-HA, the flaps were sutured by means of mattress sutures to allow primary intention healing. At 7 months after regenerative surgery, the teeth were extracted together with some of their surrounding soft and hard tissues and processed for histological analysis. RESULTS: The postoperative healing was uneventful in all cases. At 7 months following surgery, mean PPD reduction and mean CAL gain measured 4.0 ± 0.8 and 2.5 ± 0.8 mm, respectively. The histological analysis revealed a healing predominantly characterized by epithelial downgrowth. Limited formation of new cementum with inserting connective tissue fibers and bone regeneration occurred in three out of the six biopsies (i.e. 0-0.86 and 0-1.33 mm, respectively). Complete resorption of the nano-HA was found in four out of the six biopsies. A few remnants of the graft particles (either surrounded by newly formed mineralized tissue or encapsulated in connective tissue) were found in two out of the six biopsies. CONCLUSION: Within their limits, the present results indicate that nano-HA has limited potential to promote periodontal regeneration in human intrabony defects. CLINICAL RELEVANCE: The clinical outcomes obtained following surgery with OFD + nano-HA may not reflect true periodontal regeneration.

[Salvage of a tooth with necrotised periodontium, caused by endodontic use of radiosurgery. Long-term results. Case report]. / Rádiósebészeti technikával gyökérkezelt fog körül kialakult parodontális nekrózis kezelése es a fog megmentése. Hosszú távú eredmények. Esetismertetés.

Electrosurgery and radiosurgery bear certain popularity in contemporary dentistry. Nevertheless, the inadequate treatment allocation may lead to tissue necrosis. A young female patient was referred to our department following root canal treatment (RCT) by radiosurgical device. Necrotised alveolar bone, lack of keratinized gingiva and increased tooth mobility were noticed. After considering all the treatment options, we attempted to keep the tooth. Therefore, the necrotised part of the alveolar process was removed and the gingival fringe was rejuvenated alongside root surface debridement. The tooth was then splinted with glass fibre reinforced composite and appropriate RCT was completed. After ten months of improvement periodontal reconstructive surgery with deproteinized bovine bone mineral and connective tissue graft was carried out. Substantial improvement was observed at the six month reassessment, including complete healing of the gingiva. The composite splint was then removed due to discontinued mobility. The tooth and the adjacent periodontium remained stable for seven years. Nevertheless, external root resorption was recently developed that was treated with glass ionomer cement filling and regenerative periodontal surgery using enamel matrix derivative (EMD). Ultimately, the tooth is still in place providing satisfactory function and aesthetics.

[Surgical correction of excessive gingival enlargements. Case studies]. / Extrém méretu iatrogén eredetu inyhiperpláziák sebészi korrekciója. Esetsorozat.

INTRODUCTION: Gingival enlargement is a common form of periodontal tissue reaction to several irritating factors. The most common form is the drug related gingival hyperplasia--nevertheless the heredity gingival fibromatosis and hematological cases can also occur and might impose a challenge to periodontists. After a short literature summary three Case reports are presented. The first case is a drug related gingival overgrowth in a young kidney transplant women who took Cyclosporin-A. The excessive mass of fibrotic tissue was removed by a series of internal beveled incision and the oral and buccal gingival flaps were united with sutures. The healing was uneventful and during the follow up patient's compliance and oral hygiene was superb. The second case is a very severe antihypertensive drug related gingival overgrowth in a 62 years old man interfering with the closure of his lip and corrected with a combination of conventional gingivectomy and internal reverse beveled incision both and Ca-channel blockers. The third case is a 42 years old woman with chronic idiopathic hemolytic anemia who presented a sudden onset acute excessive generalized gingival enlargement accompanied with severe pain and fever. At admission she was suspect for leukemia. After obtaining biopsy samples and having negative histology the soft tissue mass was removed under general anesthesia with conventional gingivectomy technique, but after a couple of days the severe pain and gingival swelling recurred. With administering systemic corticosteroid therapy (32 mg Medrol), the gingiva healed in five days and the one year follow-up showed a stable hematological and periodontal status. Today the more conservative internal beveled incision is preferred over the conventional gingivectomy in the most cases because it provides a more predictable healing and better esthetics. The recurrence of the drug related gingival hyperplasia can be anticipated by meticulous postoperative individual oral hygiene and regular supportive therapy. CONCLUSION: The combined conservative and surgical therapy leads to predictable postoperative result even in very severe systematically motivated gingival enlargements, nevertheless the successful patients management needs good cooperation with medical doctors and with the patients themselves.

[The recombinant human parathyroid hormone, teriparatide as an alternative remedy for the medication-related osteonecrosis of the jaw]. / Humán rekombináns parathormon (teriparatid) mint alternatív megoldás a gyógyszer okozta állcsontnekrózis terápiájára.

In developed countries, osteoporosis is one of the most common debilitating conditions in the population over the age of 50. Unfortunately, the pathomechanism of the disease is still not fully understood. Nowadays, the administration of antiresorptive drugs blocking osteoclastic activity is the most commonly used medication to slow down the speed of the bone loss. One of the uncommon side effects of such drugs is the medication-related osteonecrosis of the jaw (MRONJ). Recently, a number of alternative therapeutic approaches has been tested and published, amongst them the recombinant human parathyroid hormone (rhPTH, teriparatide) use, which is turning into a promising treatment modality. According to certain meta-analyses, its pharmacological effect on increasing bone mineral density and controlling pathological vertebral fractures is superior to antiresorptive drugs; however, the so-called "off-label" application of teriparatide remains controversial. As intermittent administration of teriparatide stimulates bone formation, several animal and clinical studies indicated that systemic application of teriparatide shortened fracture healing time and improved quality of the callus and the newly formed bone. Furthermore, recently several clinical studies showed the beneficial effect of the intermittent rhPTH administration in the management of MRONJ. This article reviews the history of the anabolic effect of the low-dose rhPTH discovery, provides evidence-based data from animal and human studies, summarizes its biological mechanisms and the clinical benefits of the anabolic therapy and also their possible role in the management of MRONJ. The majority of the clinical data indicates that, in the case of therapy-resistant osteonecrosis, it may be worthwhile to apply short-term intermittent teriparatide therapy. Notwithstanding, more randomized clinical trials are necessary in order to confirm the efficacy and the safety of the use of teriparatide in the treatment of MRONJ.

Utilizing a novel radiographic image segmentation method for the assessment of periodontal healing following regenerative surgical treatment.

OBJECTIVE: The aim of the current article was to present a radiographic method to determine the surface area of newly formed periodontal attachment, as well as to analyze volumetric and morphologic changes after regenerative periodontal treatment. METHOD AND MATERIALS: In this retrospective study, 11 singular intrabony periodontal defects were selected for minimally invasive surgical treatment and 3D evaluation. 3D virtual models were acquired by the segmentation of pre- and postoperative CBCT scans. This study determined the surface area of baseline periodontal attachment (RSA-A) and defect-involved root surface (RSA-D) on the preoperative 3D models, and the surface area of new periodontal attachment (RSA-NA) on the postoperative models. Finally, cumulative change of periodontal attachment (∆RSA-A) was calculated and Boolean subtraction was applied on pre- and postoperative 3D models to demonstrate postoperative 3D hard tissue alterations. RESULTS: The average RSA-A was 84.39 ± 33.27 mm2, while the average RSA-D was 24.26 ± 11.94 mm2. The average surface area of RSA-NA after regenerative periodontal surgery was 17.68 ± 10.56 mm2. Additionally, ∆RSA-A was determined to assess the overall effects of ridge alterations on periodontal attachment, averaging 15.53 ± 12.47 mm2, which was found to be statistically significant (P = .00149). Lastly, the volumetric hard tissue gain was found to be 33.56 ± 19.35 mm3, whereas hard tissue resorption of 26.31 ± 38.39 mm3 occurred. CONCLUSION: The proposed 3D radiographic method provides a detailed understanding of new periodontal attachment formation and hard tissue alterations following regenerative surgical treatment of intrabony periodontal defects.

A phase IIa randomized controlled clinical and histological pilot study evaluating rhGDF-5/ß-TCP for periodontal regeneration.

AIM: The primary objective of this study was to clinically and histologically evaluate periodontal wound healing/regeneration following surgical implantation of recombinant human growth/differentiation factor-5 (rhGDF-5) adsorbed onto a particulate ß-tricalcium phosphate (ß-TCP) carrier rhGDF-5/ß-TCP into periodontal defects in man. MATERIAL & METHODS: Twenty chronic periodontitis patients, each with at least one tooth scheduled for extraction exhibiting a probing depth ≥6 mm and an associated intra-bony defect ≥4 mm participated in the study upon written informed consent. Subjects (one defect/patient) were randomized to receive open flap debridement (OFD) + rhGDF-5/ß-TCP (n = 10) or OFD alone (control; n = 10). Block biopsies of the defect sites were collected at 6 months post-surgery and prepared for the histological evaluation. Two masked examiners evaluated the deepest aspect of each defect site relative to bone (height/area), periodontal ligament (PDL) and cementum regeneration, and residual ß-TCP. RESULTS: Sites receiving rhGDF-5/ß-TCP showed numerically greater PD reduction (3.7 ± 1.2 versus 3.1 ± 1.8 mm; p = 0.26), less gingival recession (0.5 ± 0.8 versus 1.4 ± 1.0 mm; p < 0.05) and greater clinical attachment level (CAL) gain (3.2 ± 1.7 versus 1.7 ± 2.2 mm; p = 0.14) at the deepest aspect of the defect compared with OFD alone. One biopsy in the rhGDF-5/ß-TCP and four biopsies in the OFD group were deemed as not evaluable. Histologically, bone regeneration height was almost threefold greater for the rhGDF-5/ß-TCP treatment compared with OFD alone (2.19 ± 1.59 versus 0.81 ± 1.02 mm; p = 0.08). Similarly an almost twofold increase was observed for PDL (2.16 ± 1.43 versus 1.23 ± 1.07 mm; p = 0.26), cementum (2.16 ± 1.43 versus 1.23 ± 1.07 mm; p = 0.26) and bone regeneration area (0.74 ± 0.69 versus 0.32 ± 0.47 mm(2) ; p = 0.14). Root resorption/ankylosis was not observed. Residual ß-TCP occupied 8.4 ± 11.5% of the area of interest in biopsies of patients receiving rhGDF-5/ß-TCP. Five biopsies (one rhGDF-5/ß-TCP, four OFD) were deemed unsuitable to allow a meaningful histological or histometrical evaluation. CONCLUSIONS: Descriptive statistics showed greater PD reduction and CAL gain, and greater alveolar bone regeneration and periodontal regeneration at sites that received rhGDF-5/ß-TCP compared to control. However, these differences were not statistically significant. Future studies with larger sample sizes will have to be conducted to verify these findings.

[The management of a single Miller-I type gingival recession at the maxillar incisor with single tunnel technique combined with enamel matrix derivative and connective tissue graft. A case report]. / Felso metszofogat erinto Miller-I típusú inyrecessio korrekciója zománcmátrix-proteinnel kombinált subepithelialis kötoszöveti Graft-tal es Single Tooth Tunnel technikával. Esetismertetés.

Gingival recession defect in the dentition are routinely encountered in periodontal practice and presents a challenge for a periodontist. Mucogingival surgical procedures aim to restore both gingival function and aesthetics. Recently as the population is getting to be more concerned about aesthetics the aesthetical indications are more relevant. In the presented case a coronally advanced flap prepared by single tunnel technique and combined with subepithelial connective tissue graft and enamel matrix derivatives (EMD) has been employed for root coverage in a Miller's class I recession. The combined technique used resulted in approximately 100% root coverage in the treated site after 6 months. Treatment outcomes met the patient's aesthetic demands and also eliminated her root sensitivity.

[Control of generalized chronic periodontitis combined with calcium-antagonist-related gingival overgrowth by a complex periodontal-endodontic-prosthodontic treatment. Case report]. / Ca-csatorna-blokkoló antihipertenzív gyógyszert szedo, generalizált krónikus parodontitisben szenvedo nobeteg komplex parodontális-protetikai ellátása. Esetismertetés.

To day a relatively high percentage of elderly population of the industrialized world suffers with different cardiovascular diseases and are on permanent antihypertensive therapy. One of the most frequently used drugs is the calcium channel blockers prescribed against high blood pressure. The most common oral side effect of these drugs is the gingival enlargement that might develop even on otherwise healthy gingiva. The incidence of chronic periodontitis in this age group is also high and the Ca antagonist medication in those individuals might substantially modify the clinical course of periodontal inflammation leading to gingival enlargement and hypertrophic pocket wall. The case presented here is a 52 years old hypertonic woman with a long history of Ca-antagonist therapy and generalized chronic periodontitis combined with gingival hyperplasia. After the change of medication the 1,5 years comprehensive periodontal endodontic and prosthodontic therapy restored patient's periodontal health and provided complex dental rehabilitation. Nevertheless, only regular periodontal supportive therapy could ensure predictable outcome and guarantee long lasting periodontal health.

[Oral health assessment of Hungarian adult population based on epidemiologic examination]. / A hazai felnott lakosság parodontális allapota epidemiológiai felmérés alapján.

A representative national survey by the dentists of the Department of Prosthodontics, Semmelweis University was performed to assess oral health conditions of Hungarian adult population before joining the European Union. The aim of this study was to evaluate periodontal conditions of the population from data collected in the survey and to investigate the associations between gender, age and demographic regions and the prevalence of periodontal problems. The 2 years long nationwide investigation followed the WHO criteria (World Health Organization, 1997) and assessed 4606 person throughout all regions of the country. Periodontal conditions and treatment needs of 4153 person were assessed in intraoral examinations by Community Periodontal Index (CPI) method. Age, gender, demographic regions were recorded on questionnaires. According to our findings CPI 2 was the most frequent finding in all age groups which primarily reflected poor oral hygiene. When we consider gender differences, CPI 3 and CPI 4 were more frequent among males while women had CPI 0 and CPI 2 with higher frequency. Our findings reflect regional differences of periodontal health conditions as 16% of the population of the capitol and its surroundings had healthy periodontal condition however we could find CPI 0 only in 5-8% of Middle and South-Danubium population. Findings of our epidemiologic survey call attention on poor oral hygene of the population. There is a need in Hungary for better oral health education of the population, more preventive programs and action plans to promote regular dental office attendance.

[Risk assessment of periodontal disease in Hungary]. / A hazai felnott lakosság fogágyállapotának és a parodontális státuszt befolyásoló rizikótényezok öszefüggéseinek vizsgálata.

In this study, risk determinants were assessed for periodontal disease in the oral health survey of a representative Hungarian adult population sample. 4153 individuals participated in the study after formal consent. Participants were questionned on level of education, dental office attendance, smoking habits, oral hygiene habits and general health conditions. Quality of fixed partial dentures (FPD) were evaluated. Periodontal health status was assessed with the CPI method according to WHO criteria. When the prevalence of CPI scores was assessed by educational level, significant differences were found between groups. With increasing levels of education, a significantly higher percentage of subjects visited the dental office regularly. Higher prevalence of CPI 0 was found among those with higher level of education but there was also high prevalence of CPI 2, representing bad oral hygiene in the highly educated group. Findings of our study showed high percentage (66%) of the population attending the dental office only in case of emergency. The investigation revealed destructive effect of unsatisfactory construction of FPD on the periodontium. Healthy periodontium (CPI 0) was found among 16% of those wearing no FPD and 9% among FPD-wearers. The prevalence of deep periodontal pockets (CPI 4) was 1,6 times higher among smokers as non-smokers. Oral health statistics play an important role in planning for improvement of dental health care. Hungary needs effective prevention programs and emphasize on regular dental office attendance of individuals to improve the nation's oral health status.

Treatment of class III multiple gingival recessions: a randomized-clinical trial.

BACKGROUND: The aim of this controlled randomized split-mouth study was to evaluate whether a modified tunnel/connective tissue graft (CTG) technique - enamel matrix derivative (EMD) combination will improve the treatment of multiple class III recession when compared with the same technique alone. MATERIALS AND METHODS: Twenty healthy subjects with a mean age of 31.7 years, were enrolled for the trial in a university periodontal clinic. Patients with at least three adjacent gingival recessions on both sides of the mouth were treated with a modified tunnel/CTG technique. On the test side, an EMD was used in addition. Clinical parameters were measured at baseline, 28 days, 3, 6 and 12 months after the surgery. Results are presented at the subject level. RESULTS: The mean root coverage from baseline to 1 year post-surgery was 82% for the test group and 83% for the control group. Complete root coverage was achieved at 1 year in eight (38%) of the 20 surgeries (experimental and control group). CONCLUSIONS: One-year results indicate that the modified tunnel/CTG technique is predictable for the treatment of multiple class III recession-type defects. The addition of EMD does not enhance the mean clinical outcomes.

[Combined conservative-surgical management of generalized aggressive periodontitis: case presentation]. / Generalizált agresszív parodontitis kombinált konzervatív-sebészi kezelése: esetismertetés.

The aggressive periodontitis is a well-defined clinical entity markedly differing from the chronic form of periodontitis. A localized and a generalized form can be distinguished. The main bacterial etiologic factor for the localized form is A. actinomycetemcomitans. It mainly starts in the first quarter of ones life. The magnitude of clinical attachment loss is not proportional to the amount of local biofilm and plaque retentive factors. The rapid, mostly vertical type of bone destruction is very characteristic. In many cases the attachment loss is localized to only a few teeth, but it may spread and progress to the generalized form, affecting practically the whole dentition. In that case a mixed Gram-negative anaerobic biofilm is present subgingivally, but the AA can also dominate the pocket flora. Its treatment is very complex and time-consuming, and needs perfect patient compliance. Predictable clinical results can only be achieved by a combined conservative-surgical therapy. The corrective phase of the comprehensive treatment and patient's rehabilitation is crucial and mainly involves certain kind of regenerative therapy. One of the most critical phases is the supportive therapy. This can give a good chance to stop the progression of attachment loss and prevent the recurrence of the active disease. The presented case is to demonstrate how time-consuming a 32-year-old female patient's comprehensive periodontal therapy was, who had suffered with active aggressive periodontitis at admittance. The extensive disease control period followed by a relatively long follow-up and finished with a series of regenerative surgery could ensure a predictable outcome that might be maintained over a long period of time with regular supportive therapy.
