Could Poor Periodontal Status be a Warning Sign for Worse Pregnancy Outcome?

PURPOSE: The aim of the present study was to analyse the role of the main diagnostic signs of poor periodontal status, probing depth (PD) ≥4 mm and bleeding on probing (BOP) ≥50%, both simultaneously and individually in preterm birth (PB) and their effect on the birth weight (BW). Prematurity is a major health concern and it is the leading contributing factor to neonatal morbidity and mortality worldwide. Conflicting results exist on the relation between poor maternal, periodontal status and adverse pregnancy outcome, including preterm deliveries and low birth weight (LBW). MATERIALS AND METHODS: Seventy-seven PBs and 165 deliveries at term were analysed out of 242 patients. The perinatal factors such as gestational age (GA) and BW were analysed by BOP, categorised as ≥50% (high BOP) vs <50% (non-high BOP) and PD ≥4 mm vs <4 mm, in combination or separately. RESULTS: The obtained results suggest that maternal periodontal inflammation, represented particularly by BOP, might be a triggering factor and can be associated with PB and LBW. For women with high BOP the adjusted odds ratio (AOR) for LBW was 2.28-fold and they were likely to have PB, with a 2.02-fold higher rate. CONCLUSION: An increasing tendency of BOP seemed to be associated with a tendency to PB and LBW. Further investigations are necessary to underline this relationship, but the role of good oral health status in general, and particularly in case of pregnancy, is unequivocal.

[Effect of the treatment of periodontal disease on the outcome of pregnancy]. / Fogágybetegség kezelésének hatása a terhesség kimenetelére.

INTRODUCTION: Correlations between periodontitis and its effects on the outcome of pregnancies are actually more focused topics. Maternal motivation for a good oral hygiene and preventive dental treatment must be highlighted tasks during pregnancy care. AIM: The authors analysed the effect of the preventive dental treatment during pregnancy and its obstetrical effects. METHOD: In a prospective randomised study, including pregnant women observed for threatening preterm deliveries, patients with dental examination (n = 71) were compared with patients undergoing dental treatment at the same time (n = 79). STATISTICAL ANALYSIS: Univariate comparisons for categorical variables were assessed by χ2 tests and independent Student's t-tests for continuous variables. ORs were compared with Mantel-Haenszel tests. Multivariable logistic regression was performed to evaluate the factors determining the poor periodontal parameters and gingivitis separately. The two-tailed statistical significance level was set at 5%. RESULTS: In the dental treatment group, the neonatal birth weight was significantly higher than in the non-treated group, in case of patients with periodontitis (2990 ± 582.3 g vs 2568.1 ± 699.1 g, p = 0.005). Also the average age at delivery was significantly higher in the treated vs non-treated groups (37.3 ± 1.9 vs 36.0 ± 2.9 weeks, p = 0.027), and the treatment had a beneficial effect on the prolongation of pregnancy, with a higher level of significance in the gingivitis group vs patients with periodontitis groups (p = 0.02 vs p = 0.043). CONCLUSIONS: Dental treatment of expecting women has a beneficial effect on the prolongation of pregnancy by decreasing the rate of prematurity and perinatal complications.

Change in the Caries Status of Pregnant Women in Southeast Hungary and Its Background.

PURPOSE: To examine the caries status of pregnant women in southeast Hungary and compare the results with a similar study completed in the same region ten years earlier to determine whether any improvement has taken place in the past decade. Another objective was to assess the effects of age, socioeconomic status and number of pregnancies on oral health. MATERIALS AND METHODS: The dental examination of 130 pregnant women was carried out at the Dental Clinic of University of Szeged, Faculty of Dentistry in 2011-2013 (group 1). Caries status was examined according to WHO guidelines. In order to compare demographic and socioeconomic factors with DMF indices, find the decisive influencing factors and compare the results with the results of the previous study (group 2), two-way ANOVA and regression analyses were conducted. RESULTS: The number of highly educated, professional, urban participants included in the present group (group 1) was greater compared with that of group 2. Despite the higher age of the pregnant women in present study, statistically significantly lower DMFT (10.05 vs 12.57, p = 0.008) and DMFS (19.41 vs 26.26, p = 0.001) scores were found than ten years ago. In both studies, the regression analyses showed that women's age was the main contributing factor to caries status. CONCLUSION: The lower DMFT and DMFS values and the participants' willingness to participate in the dental screening in the present study group were probably the result of their higher educational background and that they worked as professionals.

Idiopathic male infertility related to periodontal and caries status.

OBJECTIVES: This study was undertaken to evaluate the possible correlation between the periodontal and dental status and sperm pathology in idiopathic male infertility. METHODS: The periodontal and caries status and semen quality of 199 men presented with unexplained male infertility were examined. Periodontal and dental factors were analysed by sperm pathology categories. RESULTS: A total of 106 men had normal sperm parameters, whereas 93 men had some type of spermpathology; 27.95% had oligozoospermia, 23.65% asthenozoospermia, 16.12% cryptozoospermia, 32.25% combined oligo-asthenozoospermia. Poor periodontal status was found in about half of the study group (45.7%). The DMFT index was not a significantly higher in any of the spermpathology groups. The odds ratio of calculus, bleeding on probing (BOP) and BOP at ≥50% of the teeth were significantly higher in the combined group (AOR = 1.04, AOR = 1.13, AOR = 4.92, respectively) in multivariate analyses compared to those in the normozoospermia group. Gingival bleeding in the history and urban residency were the only predictors for pathospermia shown by the logistic regression model (AORs were 1.82 and 2.26, respectively). CONCLUSIONS: Some features of poor periodontal status, as gingival bleeding in the history, presence of calculus and BOP, were associated with oligo+asthenozoospermia in men with idiopathic infertility.

Association between periodontal status and idiopathic male infertility.

About 30% of male infertility cases are idiopathic. Previous studies reported a positive correlation between deep periodontal pockets and sperm sub-motility, which suggests that periodontitis might have a role in idiopathic semen abnormality pathospermia. We evaluated correlations between periodontal infection parameters and the results of sperm analysis of men with idiopathic infertility. In this observational study, semen quality and periodontal status were analyzed for 95 otherwise healthy men attending an andrology unit for sperm analysis. Half the men in the sperm pathology and normozoospermia groups (50.8% and 50%, respectively) had poor periodontal status. Among the 95 participants, 38% had oligozoospermia, 28% had asthenozoospermia, 16% had cryptozoospermia, and 15% were classified as normozoospermic. Sperm pathology category was not associated with frequency of deep periodontal pockets or calculus. Bleeding on probing was significantly lower among men with asthenozoospermia than among those with normozoospermia. Poor periodontal status was not associated with any sperm pathology category or parameter. In contrast with previous findings, the present results indicate that pathospermia and poor semen quality are not associated with periodontal infection in men with idiopathic infertility.

[Pregnant women's oral hygiene knowledge and habits after the second millennium in South-East Hungary]. / Terhes nok szájhigiénés ismeretei, szokásai az ezredfordulón Délkelet-Magyarországon.

Among the predisposing agents for inflammatory periodontal lesion dental plaque is the most important, but different local and systemic factors may influence the seriousness or progression of periodontitis. Hormonal changes during pregnancy belong to the systemic aggravating factors. The aim of the present study was to assess pregnant women's oral hygiene knowledge and habits, and if these have a relationship with age, residence, educational level and profession/occupation. Questionnaires were used for the data collection. 275 pregnant women, who underwent prenatal care at the Department of Obstetrics and Gynecology in Szeged, volunteered to answer the questions. The results showed that almost all the women brushed their teeth daily, but only about one third of them used special oral hygiene tools, like dental floss. Many of the women claimed to have gingival bleeding when brushing their teeth. More then 70% visited a dentist during pregnancy. There was a significant relationship between educational level and the use of dental floss (p=0.004) and gingival bleeding (p=0.023) Oral hygiene education, dental and periodontal treatment of pregnant women need more emphasis during prenatal care.

Salivary calcium concentration in relation to periodontal health of female tobacco smokers: a pilot study.

OBJECTIVE: The aim of this pilot study was to assess the possibility of differences in the calcium concentration of the saliva between smoker and nonsmoker patients with or without periodontitis. METHOD AND MATERIALS: A total of 44 women were enrolled in this study. Exclusion criteria were severe general health problems, the prescription of medication, and fewer than 16 remaining teeth. The study population comprised 24 smokers (4 periodontitis free, 16 with chronic and 4 with aggressive periodontitis; mean age 50.2 years +/- 6.9) and 20 nonsmokers (10 periodontitis free, 9 with chronic and 1 with aggressive periodontitis; mean age 54.7 years +/- 15.6). Clinical parameters (bone loss; plaque, gingival and calculus indices; and pocket depth) were recorded, and stimulated saliva samples were collected. The calcium concentration of each saliva sample was measured by atomic absorption spectrophotometry. Statistical analysis was performed with the MANOVA test. RESULTS: The mean salivary calcium level in the smokers (57.76 µg/mL +/- 18.8) was significantly (P < .05) higher than in the nonsmokers (44.6 µg/mL +/- 7.8). Periodontal examination revealed significantly greater bone loss, a deeper mean probing depth, and a higher amount of calculus (P < .05) among the smokers. However, there were no statistically significant differences between the smokers and the nonsmokers as concerns the plaque and bleeding indices. CONCLUSIONS: Within their limits, the present findings seem to indicate that patients with periodontitis who smoke exhibit higher salivary calcium levels than those in nonsmokers. However, the clinical significance of these findings remains to be determined in large-scale controlled studies.

Detection of periodontopathogenic bacteria in pregnant women by traditional anaerobic culture method and by a commercial molecular genetic method.

To culture facultative and strict anaerobic bacteria is a well-established method for analyzing subgingival plaque samples. Micro-IDent and micro-IDent Plus (HAIN Lifescience GmbH, Nehren, Germany) tests are two commercially available rapid PCR-based methods for the identification and quantification of putative periodontopathogen bacteria. In this study, we compared these commercial PCR-based hybridization methods with conventional anaerobic culture technique. A total of 36 subgingival plaque samples were collected from periodontal pockets of pregnant women with chronic localized periodontitis. Aliquots of these samples were evaluated with species-specific probes provided by micro-IDent and micro-IDent Plus tests simultaneously, and from the same samples anaerobic and capnophylic bacteria were cultured on selective media. The overall agreement between both methods was excellent for Eubacterium nodatum, Tannerella forsythia and Porphyromonas gingivalis (97-92%), fair for Capnocytophaga sp, Eikenella corrodens, Actinobacillus actinomycetemcomitans, and Prevotella intermedia (91-89%) and poor for Fusobacterium nucleatum, Parvimonas micra (Micromonas micros), and Campylobacter rectus (86-78%). Discrepancies in the results may be explained by inability of culture method to distinguish between closely related taxa (e.i P. intermedia/Prevotella. nigrescens), and problems of keeping periodontopathogen bacteria viable, which is required for successful detection by standard culture method. Nucleic acid-based methods may replace cultivation method as frequently used methods in microbiological diagnosis of progressive periodontitis, thus micro-IDent and micro-IDent Plus tests can be recommended where culture of periodontopathogenic bacteria is not performed in routine microbiology laboratories to analyze subgingival plaque samples.

Prevention of preterm delivery with periodontal treatment.

OBJECTIVE: To demonstrate the role of periodontal treatment (PT) in the prevention of preterm delivery (PD). METHODS: A comparative prospective study of two groups of pregnant women with threatening PD was carried out at the Department of Obstetrics and Gynaecology of the University of Szeged: group A (n = 39) comprised patients who were merely examined dentally for periodontitis, and group B (n = 44) consisted of patients who received periodontal treatment during pregnancy. RESULTS: Periodontitis was identified in 19 cases (48.7%) in group A and in 18 cases (40.9%) in group B. The mean birth weight of the newborns was significantly higher in group B (3,009.1 g) than in group A (2,580.8 g; p = 0.007). The rate of premature birth was significantly lower in the group who received PT (p = 0.012, odds ratio = 3.5, 95% confidence interval = 1.38-8.86). CONCLUSIONS: The PT of pregnant women can decrease the rate of premature birth and consequently lead to a better neonatal health outcome.

More publications support the statement that maternal periodontitis may be a risk factor of preterm delivery and low birth-weight, than the number of those that suggest opposing evidence. The proving or rejecting of the questionable relationship may be carried out--among other methods--by analyzing the results of interventional studies. The aim of our study was to investigate whether or not it is possible to decrease the chance of preterm birth and low birth-weight in the case of healthy non-smoking women through the elimination of periodontal inflammation by providing professional oral hygiene treatment during pregnancy. After periodontal examination 80 pregnant women received professional oral hygiene treatment including plaque and calculus removal, root planing, motivation and instruction (treatment group); only the periodontal status was recorded in 79 cases (control group). The mean length of pregnancy and birth-weight in the treatment group were compared with similar data of the control group. Data were assessed using statistical methods. The mean weight of newborns was 3005.3 grams in the treatment group, while 2644.2 grams in the control group (p < 0.0001). The delivery occurred later in the treatment group (37.0 week), than among the control group (36.4 week), although the difference was not significant (p = 0.059). In the periodontal treated group, which had a statistically suitable number of members, the periodontal treatment might have contributed to a more optimal date of delivery and to achieving a larger birth-weight.

The oral health status of postpartum mothers in South-East Hungary.

OBJECTIVES: This study was carried out to assess the oral health status of new mothers, following not more than three days post-delivery, in South-East Hungary. An additional aim was to examine the effect of socioeconomic status on the oral health of the 169 women who volunteered, all of whom were healthy. MATERIAL AND METHODS: Socioeconomic data were collected via a questionnaire, and patients were examined according to WHO guidelines. The state of the periodontium was described by examining the plaque, calculus, probing depth and bleeding on probing. The mean age of the women was 27.5 yrs, representing all educational levels and professional categories of the country. RESULTS: The mean DMFT was 12.57, and the mean DMFS was 26.26. The plaque index was 0.68, the calculus frequency 20.22%, the mean probing depth 1.65mm and bleeding on probing occurred in 36.27% of teeth. Regression analyses demonstrated that caries levels were mostly related to age and plaque scores, while the state of the periodontium was mostly related to educational level, age and profession. The number of pregnancies had no significant influence on the caries nor on the periodontal status of these women. CONCLUSIONS: It was concluded that the oral health status of these mothers was mainly age- and socioeconomically-related, and that the dental needs of women during pregnancy must be emphasized, both to the dental profession and to the patients themselves.

Possible association between mother's periodontal status and preterm delivery.

BACKGROUND: A case-control study was undertaken to detect whether initial chronic localized periodontitis could be a risk factor for preterm birth (PB) and foetal growth restriction. METHODS: A PB case was defined if a patient had a threatening premature event during pregnancy pre-term premature rupture of membranes, or spontaneous pre-term delivery, before the 37th week of pregnancy, and/or the weight of the newborn was <2500 g. Into the PB (case) group, 77 women were allocated, while 84 were included in the control group, all of whom had delivery after the 37th gestational week and with a newborn weighing >or=2500 g. RESULTS: A significant association was found between PB and initial chronic localized periodontitis, the criteria being bleeding at >or=50% of the examined teeth and having at least at one site at >or=4 mm probing depth (p=0.0001). The adjusted odds ratio for initial chronic localized periodontitis was 3.32, 95% CI: 1.64-6.69. The average weight of newborns of mothers with periodontitis was significantly less than that of the women without periodontitis (p=0.002). CONCLUSIONS: The results support the hypothesis that initial chronic localized periodontitis of pregnant women could lead to PB, and birth-weight reduction.

Distribution of anaerobic bacteria among pregnant periodontitis patients who experience preterm delivery.

The preterm delivery of low-birth-weight (PLBW) infants remains a significant public health issue and a leading cause of neonatal death and of long-term neurodevelopmental disturbances and health problems. Epidemiological and immunological studies have suggested that periodontal disease may be an independent risk factor for PLBW. The incidence of periodontal disease during pregnancy has been found to be associated with a significantly lower birth weight for gestational age after adjustment for race, parity and baby gender. The present case-control study, carried out to examine the distribution of anaerobes in pregnant women with periodontitis who experienced preterm delivery, provides microbial evidence that maternal periodontal disease and the presence of key pathogens are significant contributors to the obstetric risk of preterm delivery.

[Ten years of experience with the complex periodontal and orthodontic rehabilitation of patients with periodontal diseases]. / Fogágybetegek komplex parodontoógiai és orthodonciai kezelésével szerzett 10 éves tapasztalataink.

In periodontal diseases where the loss of periodontal tissue is very extensive, displacement of the teeth may be observed. In the interest of complete healing, periodontal treatment must be followed by orthodontic treatment in such patients. If the basic rules relating to adult patients with a reduced, but healthy periodontium are adhered to, the orthodontics can be carried out with certainty in adults who have been rehabilitated from a periodontal aspect. An improved long-term result may be observed in the patients who participate in such complex rehabilitation. Teeth that have been restored to their correct position are not only aesthetically more attractive, but also function more appropriately, are easier to keep clean, and can be treated more simply.

[Effect of occlusal therapy with FRC splint on periodontal parameters in maintenance phase]. / Intrakoronális száleroosítésu kompozitsín hatása a fogágyra a fenntartó kezelés során.

The purpose of this study was to evaluate the changes of the periodontal parameters of mobile, but splinted teeth with intracoronal fiber reinforced composite and compare to non-mobile teeth in maintenance phase. We splinted 73 teeth (29 non-mobile, 44 mobile) in 18 cases. The periodontal parameters - probing depth, gingival index (Loe-Silness, 1964), plaque index (Silness-Loe, 1965) - were monitored clinically immediately, 1 year and 2 years after complete periodontal treatment. There were scored 69 treated teeth after 1 year and 37 treated teeth after 2 years. Statistical comparisons were performed using Wilcoxon test for two related parameters and Mann-Whitney U test for two independent parameters in the software package SPSS 11.0 for Windows (SPSS, Chicago, IL, USA). There was not mobility recorded at splinted teeth neither after treatment immediately nor at recall visits. The periodontal parameters demonstrated no significant changes of probing depth (-0,08 +/- 0,41, 0,05 +/- 0,51) and gingival index (-0,32 +/- 0,79, -0,32 +/- 0,75) 1 and 2 years after complete therapy. There was significant decrease in plaque index (-0,77 +/- 0,43, -0,36 +/- 0,55) measured at recall visits. No significant differences were detected between the mobile and the non-mobile groups in all parameters. No significant correlation between changes of gingival index and plaque index was determined. The intracoronal FRC splint do not obstruct the individual and professional oral hygiene. The stabilize of mobile teeth allow the same healing like a non-mobile teeth.

[Caries and periodontal state of pregnant women. Part II. Periodontal state]. / Terhes nok kariológiai és parodontológiai állapotának felmérése II. A parodontális állapot.

A great number of clinical studies focused on the periodontal health of the pregnant women in the last decades, since an association has been presumed between the pregnant women's periodontal disease and the adverse pregnancy outcome. Altogether 161 healthy women were examined soon after delivery in Szeged/Hungary. The periodontal status of the patients was recorded by the Silness-Löe Plaque index (0.67), frequency of calculus (21.07%), mean probing pocket depth (1.67 mm) and the frequency of bleeding on probing (37.8%). A significant correlation was found between the state of the periodontium and the educational level and the pregnant women's profession. The periodontal state of women with higher education and the intellectuals was much better, than of the less educated patients and the manual workers.

[Caries and periodontal state of pregnant women. Part I. Caries status]. / Terhes nok kariológiai és parodontológiai állapotának felmérése I. A kariológiai állapot.

A misconception exists in the society regarding the caries frequency during pregnancy. The condition of the teeth of the child can be influenced by the state of the teeth and the oral hygiene habits of the mother. An examination was conducted among young women soon after delivery in Szeged/Hungary. The number of the examined patients was 161, with the average age of 27.6 years. The DMFT (Decayed, Missing, Filled Teeth) index was 12.45, while the DMFS (Decayed, Missing, Filled Surfaces) index was 26.07 in the examined population. The DMFT index significantly correlated with age, number of pregnancies, plaque index, probing pocket depth and bleeding on probing, while the DMFT index was not dependent on education level, profession and place of residency. There was no significant correlation between the number of previous pregnancy and the incidence of caries.

[Periodontal abscess: etiology, diagnosis and treatment]. / A parodontális abscessus és kezelése.

The periodontal abscess is an acute destructive process in the periodontium resulting in localized collections of pus communicating with the oral cavity through the gingival sulcus or other periodontal sites and not arising from the tooth pulp. The prevalence of periodontal abscess is relatively high and it affects the prognosis of the tooth. Periodontal abscesses can develop on the base of persisting periodontitis but can also occur in the absence of periodontitis. The cause of the development of periodontal abscess originating from chronic periodontitis is the marginal closure of a periodontal pocket, or the pocket lumen might be too tight to drain the increased suppuration due to changes in the composition of subgingival microflora, alteration of bacterial virulence or host defenses. Diagnosis of a periodontal abscess is based on medical and dental history as well as oral examination (pocket depth, swelling, suppuration, mobility, sensibility of the tooth). The most prevalent group of bacteria: P. gingivalis, P. intermedia, B. forsythus, F. nucleatum and P. micros. Previous studies have suggested that the complete therapy of the periodontitis patients with acute periodontal abscess has to do in two stages: the first stage is the management of acute lesions, then the second stage is the appropriate comprehensive treatment of the original and/or residual lesions. The management of acute lesions includes establishing drainage via pocket lumen, subgingival scaling and root planing, curettage of the lining pocket epithelia and seriously inflamed connective tissue, compressing pocket wall to underlying tooth and periodontal support, and maintaining tissue contact. Some authors recommend the incision or to establish drainage and irrigation, or a flap surgery, or even extraction of hopeless teeth. We recommend the use of systemic antibiotics as a preventive measure of systemic disease or in case of systemic symptoms.

A possible association between preterm birth and early periodontitis. A pilot study.

UNLABELLED: According to many studies, generalised periodontitis can be a risk factor for preterm birth (PB). A case-control study was carried out to examine if early localised periodontitis could be a risk factor for adverse pregnancy outcome. MATERIAL AND METHODS: Postpartum women without any systemic disease were included into the study. Similar numbers of patients belonged to the case (41) and to the control (44) groups. A PB case was defined if a patient had a threatening premature labour during pregnancy, preterm premature rupture of membranes, or spontaneous preterm labour, and/or the weight of the newborn was < or = 2499 g. Control women had delivery after the 37th gestational week and the newborn's weight was > or = 2500 g. Known risk factors like smoking, alcohol, drug consumption, socio-economic status and the periodontal status were recorded. RESULTS: A significant association was found between PB and early localised periodontitis of the patient with the following criterion having bleeding at > or = 50% of the examined sites (6 at each tooth) and having at least at one site > or = 4 mm probing depth (p = 0.001). The odds ratio was 5.46 at the 95% confidence interval. The average weight of the newborns in the periodontitis group was less than in the control group, the difference is significant (p = 0.047). CONCLUSION: The results indicate that early localised periodontitis of the patient during pregnancy can be regarded as an important risk factor for PB.

[Replacement of a missing tooth with transplantation. Case report]. / Egy sorközi foghiány pótlása transzplantációval (Esetismertetés).

The replantation and transplantation are wide-spread therapies applied in case of tooth avulsion. It is also possible for such a tooth not to get back into the original socket, and it would be replaced to another tooth alveoli. In this presented case we transplanted a wisdom tooth to the place of the first lower molar immediately after extraction. The same time, by this case we discussed the therapeutical principles and possible prognosis too.
