Diabetes mellitus has been linked with an increased risk for oral diseases, especially periodontitis. However, studies results were not consistent. The present study was conducted to evaluate whether both type 1 (T1DM) and type 2 diabetes mellitus (T2DM) are associated with increased prevalence and extent of periodontal disease and tooth loss compared with non-diabetic subjects within a homogeneous adult study population. T1DM, T2DM and non-diabetic subjects were recruited from the population-based Study of Health in Pomerania (SHIP). Additionally, T1DM subjects were retrieved from a Diabetes Centre in the same region. The total study population comprised 145 T1DM and 2,647 non-diabetic subjects aged 20-59 years, and 182 T2DM and 1,314 non-diabetic subjects aged 50-81 years. Multivariable regression revealed an association between T1DM and mean attachment loss (B=0.40 [95% CI; 0.19, 0.61], adjusted). Also, T1DM was positively associated with increased number of missing teeth after full adjustment (p<0.001). The association between T1DM and tooth loss was enhanced in subjects aged 40-49 and 50-59 years (p for interaction=0.01). In T2DM subjects, mean attachment loss was significantly higher compared with non-diabetic subjects (B=0.47 [95% CI; 0.21, 0.73], adjusted). The effect of T2DM was significantly enhanced in 60-69-years-old subjects (p for interaction=0.04). The association between T2DM and number of missing teeth was not statistically significant after adjustment (p=0.25). Analyses showed that the effect of T2DM on tooth loss was pronounced in females compared with males (p for interaction=0.01). In accordance with previous literature, present results suggested that periodontal diseases and tooth loss can been seen as a complication of both types of diabetes. Generally, periodontal diseases are preventable and treatable. Therefore, appropriate goals and strategies for improving periodontal health in subjects with diabetes need to be developed. Further, early detection and careful managed therapeutics with the physician and dentist working hand-in-hand may prove beneficial to the patient–s general health.
Zur Analyse der Beziehung zwischen Parodontitis, Fettleibigkeit und Körperkraft in der Allgemeinbevölkerung Nordostdeutschlands wurden zwei Kohorten (SHIP-2 und SHIP-Trend) aus der Region Vorpommern herangezogen. Es zeigt sich eine starke Abhängigkeit der sinkenden Muskelkraft bei steigendem Alter. Der paradontale Destruktionsgrad nimmt ebenfalls mit dem Alter zu. Die Parodontitis ist mit der Greifkraft assoziiert. Parodontal gesündere Frauen haben eine geringere Greifkraft als Männer. Aus dem Attachmentverlust resultiert ein höherer Muskelkraftverlust. Die Muskelkraft fällt umso geringer aus, je weniger Zähne vorhanden sind. Sie steigt mit zunehmendem Gewicht, sinkt jedoch bei ansteigendem Körperfettanteil. Die Fettleibigkeit scheint ein gemeinsamer Risikofaktor für die Parodontitis und für die Muskelkraftschwäche zu sein. Ein erhöhter Spiegel an Entzündungsmediatoren ist sowohl bei der Fettleibigkeit, als auch bei der Parodontitis und bei Körperkraftverlust nachweisbar. Somit spielt die Entzündung vermutlich eine zentrale Rolle in der Beziehung zwischen Parodontitis, Fettleibigkeit und Körperkraft.
The aim of the present study was to construct a biological age score reflecting one’s physiologic capability and aging condition with respect to tooth loss over 10 y. From the follow-up to the population-based Study of Health in Pomerania (i.e., SHIP-2), 2,049 participants were studied for their baseline biomarker measures 10 y before (i.e., in SHIP-0). Metabolic and periodontal data were regressed onto chronological age to construct a score designated as “biological age.” For either sex separately, the impact of this individualized score was used to predict tooth loss in the follow-up cohort in comparison with each participant’s chronological age. Outcome data after 10 y with respect to tooth loss, periodontitis, obesity, and inflammation were shown to be better for biologically younger subjects than as expected by their chronological age, whereas for the older subjects, data were worse. Especially for tooth loss, a striking increase was observed in subjects whose biological age at baseline appeared to be higher than their chronological age. Biological age produced significantly better tooth loss predictions than chronological age (P < 0.001). Areas under receiver operating characteristic curves for tooth loss of ≥3 teeth in men during follow-up were 0.811 and 0.745 for biological and chronological age, respectively. For women, these figures were 0.788 and 0.724. For total tooth loss, areas under the curve were 0.890 and 0.749 in men and 0.872 and 0.752 in women. Biological age combines various measures into a single score and allows identifying individuals at increased risk of tooth loss.
Evidence is limited regarding whether periodontal treatment improves hemoglobin A1c (HbA1c) among people with prediabetes and periodontal disease, and it is unknown whether improvement of metabolic status persists >3 mo. In an exploratory post hoc analysis of the multicenter randomized controlled trial “Antibiotika und Parodontitis” (Antibiotics and Periodontitis)—a prospective, stratified, double-blind study—we assessed whether nonsurgical periodontal treatment with or without an adjunctive systemic antibiotic treatment affects HbA1c and high-sensitivity C-reactive protein (hsCRP) levels among periodontitis patients with normal HbA1c (≤5.7%, n = 218), prediabetes (5.7% < HbA1c < 6.5%, n = 101), or unknown diabetes (HbA1c ≥ 6.5%, n = 8) over a period of 27.5 mo. Nonsurgical periodontal treatment reduced mean pocket probing depth by >1 mm in both groups. In the normal HbA1c group, HbA1c values remained unchanged at 5.0% (95% CI, 4.9% to 6.1%) during the observation period. Among periodontitis patients with prediabetes, HbA1c decreased from 5.9% (95% CI, 5.9% to 6.0%) to 5.4% (95% CI, 5.3% to 5.5%) at 15.5 mo and increased to 5.6% (95% CI, 5.4% to 5.7%) after 27.5 mo. At 27.5 mo, 46% of periodontitis patients with prediabetes had normal HbA1c levels, whereas 47.9% remained unchanged and 6.3% progressed to diabetes. Median hsCRP values were reduced in the normal HbA1c and prediabetes groups from 1.2 and 1.4 mg/L to 0.7 and 0.7 mg/L, respectively. Nonsurgical periodontal treatment may improve blood glucose values among periodontitis patients with prediabetes (ClinicalTrials.gov NCT00707369).
Abstract
Objective
To evaluate the efficacy of tooth splinting (TS) and occlusal adjustment (OA) compared to no TS or OA in patients with periodontitis exhibiting masticatory dysfunction.
Material
The primary outcome criterion was tooth loss (TL), and the secondary outcome parameters were change in probing pocket depth (PPD), change in clinical attachment level (CAL), tooth mobility (TM), and patient‐reported outcome measures (PROMs). Literature search was performed on three electronic databases (from 01/1965 to 04/2021) and focused on clinical studies with at least 12 months follow‐up.
Results
From a total of 1515 publications, 51 articles were identified for full‐text reading, of which 2 retrospective case series on TS with low risk of bias and 1 randomized and 2 prospective studies on OA with unclear risk of bias were included. For TS, synthesis of data showed that in 72 patients, 26 out of 311 teeth (weighted mean incidence of TL 8.4%) and 156 out of 1541 teeth with no TS (weighted mean incidence of TL 10.1%) were lost over 2 years following non‐surgical periodontal therapy. The randomized controlled clinical trial (RCT) indicated CAL gain for teeth with OA compared to no OA. For the effect of OA on TL, PPD, and TM, heterogeneous data were retrieved from the included studies.
Conclusions
Within the limitations of this review and based on a low level of evidence, it is concluded that TS does not improve survival of mobile teeth in patients with advanced periodontitis. OA on teeth with mobility and/or premature contacts may lead to improved CAL, while the effect of OA on the remaining periodontal parameters remains unclear.
The long-term effectiveness of powered toothbrushes (PTBs) and interdental cleaning aids (IDAs) on a population level is unproven. We evaluated to what extent changes in PTB and IDA use may explain changes in periodontitis, caries, and tooth loss over the course of 17 y using data for adults (35 to 44 y) and seniors (65 to 74 y) from 3 independent cross-sectional surveys of the German Oral Health Studies (DMS). Oaxaca decomposition analyses assessed to what extent changes in mean probing depth (PD), number of caries-free surfaces, and number of teeth between 1) DMS III and DMS V and 2) DMS IV and DMS V could be explained by changes in PTB and IDA use. Between DMS III and V, PTB (adults: 33.5%; seniors: 28.5%) and IDA use (adults: 32.5%; seniors: 41.4%) increased along with an increase in mean PD, number of caries-free surfaces, and number of teeth. Among adults, IDA use contributed toward increased number of teeth between DMS III and V as well as DMS IV and V. In general, the estimates for adults were of lower magnitude. Among seniors between DMS III and V, PTB and IDA use explained a significant amount of explained change in the number of caries-free surfaces (1.72 and 5.80 out of 8.44, respectively) and the number of teeth (0.49 and 1.25 out of 2.19, respectively). Between DMS IV and V, PTB and IDA use contributed most of the explained change in caries-free surfaces (0.85 and 1.61 out of 2.72, respectively) and the number of teeth (0.25 and 0.46 out of 0.94, respectively) among seniors. In contrast to reported results from short-term clinical studies, in the long run, both PTB and IDA use contributed to increased number of caries-free healthy surfaces and teeth in both adults and seniors.
Periodontitis is a multifactorial disease. The aim of this explorative study was to investigate the role of Interleukin-(IL)-1, IL-4, GATA-3 and Cyclooxygenase-(COX)-2 polymorphisms after non-surgical periodontal therapy with adjunctive systemic antibiotics (amoxicillin/metronidazole) and subsequent maintenance in a Caucasian population. Analyses were performed using blood samples from periodontitis patients of a multi-center trial (ClinicalTrials.gov NCT00707369=ABPARO-study). Polymorphisms were analyzed using quantitative real-time PCR. Clinical attachment levels (CAL), percentage of sites showing further attachment loss (PSAL) ≥1.3 mm, bleeding on probing (BOP) and plaque score were assessed. Exploratory statistical analysis was performed. A total of 209 samples were genotyped. Patients carrying heterozygous genotypes and single-nucleotide-polymorphisms (SNP) on the GATA-3-IVS4 +1468 gene locus showed less CAL loss than patients carrying wild type. Heterozygous genotypes and SNPs on the IL-1A-889, IL-1B +3954, IL-4-34, IL-4-590, GATA-3-IVS4 +1468 and COX-2-1195 gene loci did not influence CAL. In multivariate analysis, CAL was lower in patients carrying GATA-3 heterozygous genotypes and SNPs than those carrying wild-types. For the first time, effects of different genotypes were analyzed in periodontitis progression after periodontal therapy and during supportive treatment using systemic antibiotics demonstrating a slight association of GATA-3 gene locus with CAL. This result suggests that GATA-3 genotypes are a contributory but non-essential risk factor for periodontal disease progression.
Die Parodontitis gehört zu den häufigsten Erkrankungen des Menschen. Als Reaktion des Immunsystems auf die bakterielle Besiedlung der Mundhöhle mit parodontal-pathogenen Mikroorganismen, kommt es zur Zerstörung des Parodontiums. Das Gram-negative Bakterium A. actinomycetemcomitans (A.a.)wird dabei als Haupterreger der Parodontitis beschrieben. Ziel der vorliegenden Arbeit war die Charakterisierung einer experimentell-induzierten Parodontitis in der Maus. Es wurden C57BL/6J-Wildtyp-Mäuse, iNOS-KO- und gp91-phox-KO-Mäuse oral mit A.a. infiziert. Fünf Wochen nach Ende der Infektionen konnte signifikant Knochenabbau sowohl morphometrisch als auch volumetrisch mittels Computertomografie in gp91-phox-KO-Mäusen, verglichen mit infizierten C57BL/6J-Wildtyp-, infizierten iNOS-KO-Mäusen und den Kontrollen, nachgewiesen werden. Unterschiede in der Kolonisationsdauer von A.a. in den verschiedenen Mausstämmen zu verschiedenen Zeitpunkten konnten zwischen den drei Untersuchungsgruppen festgestellt werden. Mit 38 Tagen nach Ende der Infektionen konnte A.a. in gp91-phox-KO-Mäusen am längsten nachgewiesen werden. Eine Korrelation zwischen Kolonisationsdauer von A.a. und parodontalem Knochenabbau konnte in gp91-phox-KO-Mäusen signifikant, im Vergleich zu infizierten iNOS-KO- und Wildtyp-Mäusen sowie den Kontrollgruppen, belegt werden. Die Ergebnisse lassen vermuten, dass die NADPH-Oxidase der polymorphkernigen neutrophilen Granulozyten oder Makrophagen bedeutend für die Abwehr von A.a. ist und somit vor der Ausbildung einer Parodontitis schützt.
