RESUMEN
OBJECTIVES: Dental research typically targets multiple outcomes. Interdental cleaning devices such as interdental brushes (IB) and water jet devices (WJ) share a sizable portion of the medical device market. However, recommendations for device selection are limited by the conflicting evidence from multiple outcomes in available studies and the lack of an appropriate synthesis approach to summarize evidences taken from multiple outcomes. In particular, both pairwise meta-analyses and single-outcome network meta-analyses can give discordant results. The purpose of this multioutcome, Bayesian network meta-analysis is to introduce this innovative method to the dental research community using data from interdental cleaning device studies for illustrative purposes. METHODS: We reanalyzed a network meta-analysis of interproximal oral hygiene methods in the reduction of clinical indices of inflammation, which included 22 trials assessing 10 interproximal oral hygiene aids. We focused on the primary outcome of gingival inflammation, which was measured by 2 correlated outcome variables, the Gingival Index (GI) and bleeding on probing (BOP). RESULTS: In our previous single-outcome analysis, we concluded that IB and WJ rank high for reducing gingival inflammation while toothpick and flossing rank last. In this multioutcome Bayesian network meta-analysis with equal weight on GI and BOP, the surface under the cumulative ranking curve was 0.87 for WJ and 0.85 for IB. WJ and IB remained ranked as the 2 best devices across different sets of weightings for the GI and BOP. CONCLUSION: In conclusion, multioutcome Bayesian network meta-analysis naturally takes the correlations among multiple outcomes into account, which in turn can provide more comprehensive evidence.

OBJECTIVES: To examine associations between periodontal disease severity and clinical and microbiological measures of caries in adults. MATERIALS AND METHODS: A cross-sectional study of 94 healthy adults ((mean ± SD) 55.4 ± 13.0 years) was conducted. Data were collected by means of questionnaire and a clinical examination that included the Decayed, Missing, Filled teeth Surfaces (DMFS) index, probing depth (PD), clinical attachment level (CAL), and gingival bleeding and plaque scores. Supra- and subgingival plaque samples were collected to assess the presence of Streptococcus mutans and six periodontal pathogens. Participants were subsequently categorized using Center for Disease Control and Prevention/American Academy of Periodontology (CDC-AAP) definitions and tertiles of percentage of sites with CAL ≥ 3mm. RESULTS: Significant positive associations were found between the periodontal disease severity (CDC-AAP) and the DMFS (aOR = 1.03; 95% CI 1.01-1.05) and DS indices (aOR = 1.18; 95% CI 1.05-1.32) as well as between the tertiles of percentage of sites with CAL ≥ 3 mm and DMFS (aOR = 1.03; 95% CI 1.00-1.05) and DS indices (aOR = 1.12; 95% CI 1.00-1.25). A significant positive association was also found between oral levels of F. nucleatum and S. mutans (aOR = 6.03; 95% CI 1.55-23.45). CONCLUSIONS: A small but positive association was found between clinical measures of caries and periodontal disease severity. Further research is warranted to examine the association between these two common oral diseases. CLINICAL RELEVANCE: Periodontal diseases and caries are the two most common oral diseases. There was a positive association between clinical and microbiological markers of both diseases. Therefore, strategies in oral health education should involve both caries and periodontitis prevention.

AIM: The recent ADA-commissioned Clinical Practice Guideline on the nonsurgical treatment of chronic periodontitis has provided the most exhaustive library of clinical trials on scaling and root planing (SRP) with or without adjuncts. This network meta-analysis (NMA) compared the adjuncts against each other. MATERIALS AND METHODS: A star-shaped NMA was performed based on 36 indirect comparisons of clinical attachment-level (CAL) gains among nine adjuncts in 74 studies from the Clinical Practice Guideline. RESULTS: All pairwise differences were accompanied by wide confidence intervals, and none of the adjuncts were statistically significantly superior to another. Local doxycycline hyclate and photodynamic therapy with a diode laser had the highest probabilities for ranking first and second, respectively. Publication bias was evident, with fewer than expected studies with small effects. The lack of these studies inflated the treatment effects by an estimated by 20%. CONCLUSIONS: Adjuncts improve CAL gain by about a third of a mm over 6-12 months compared with SRP alone, but no significant differences were found among the adjuncts. The patient-perceived benefit of this gain is unclear because CAL is a physical measure made by the clinician and not a patient-oriented outcome. Publication bias inflated the observed treatment effects.

PURPOSE: To analyze serum markers of bone turnover, angiogenesis, endocrine function, and inflammation in patients with bisphosphonate-related osteonecrosis of the jaw (BRONJ) who discontinued long-term intravenous bisphosphonate (BP) therapy. PATIENTS AND METHODS: Serum samples were obtained from 25 BRONJ patients who had discontinued long-term intravenous BP therapy for an average of 11.4 ± 8.7 months and 48 non-BRONJ controls who continued receiving intravenous BP therapy. Samples were analyzed for total alkaline phosphatase, bone-specific alkaline phosphatase, osteocalcin, C-telopeptide, vascular endothelial growth factor, triiodothyronine, thyroxine, thyroid-stimulating hormone, 25-hydroxyvitamin D, and C-reactive protein. RESULTS: The mean number of BP infusions was significantly higher in BRONJ patients compared with controls (38.4 ± 26.3 infusions vs 18.8 ± 7.2 infusions, P < .0001); however, the duration of BP therapy was not significantly different between the groups (P = .23). Overall, there were no significant differences in any of the markers between BRONJ patients and controls (all P values ≥ .16). In a subgroup analysis that matched BRONJ patients and controls according to mean age and number of BP infusions (10 BRONJ patients and 48 controls), log10 vascular endothelial growth factor (2.9 ± 0.4 pg/mL vs 2.4 ± 0.4 pg/mL, P < .001) and C-reactive protein (34 ± 26 mg/L vs 13 ± 8 mg/L, P < .01) levels were significantly higher in BRONJ patients compared with controls. Within BRONJ patients, none of the serum markers were correlated with duration of BP discontinuation. CONCLUSIONS: Levels of bone turnover and endocrine markers in BRONJ patients who discontinue long-term intravenous BP therapy are similar to those in non-BRONJ controls receiving intravenous BP therapy. However, levels of angiogenesis and inflammation markers are higher in BRONJ patients who discontinue long-term intravenous BP therapy. The prolonged skeletal half-life of BPs may suppress bone turnover markers in BRONJ patients for several years after discontinuation of intravenous BP therapy, suggesting an extended effect on bone homeostasis.

AIM: Low-dose aspirin has been hypothesized as being a potential host modulatory agent for periodontitis treatment. We investigated the relationship between low-dose aspirin use and periodontitis prevalence in the continuous National Health and Nutrition Examination Survey, 2011-2012. METHODS: We analysed n = 2335 adult men and women who received a full-mouth periodontal examination and responded to an aspirin use questionnaire. Periodontal disease was defined as severe, moderate or mild according to established case definitions. Mean full-mouth probing depth, attachment loss and tooth loss were also considered. Low-dose aspirin was defined by any self-reported, physician prescribed aspirin use of ≤162 mg/day. RESULTS: Participants had mean age (SE) 55.8 years (0.42). The prevalences of periodontitis and low-dose aspirin use were 49.5% and 25% respectively. In multivariable logistic regression models controlling for age, sex, race, socioeconomic variables and comorbidities, the odds ratios [95%CI] for moderate or severe periodontitis among low-dose aspirin users (versus non-users) were: 0.91 [0.56-1.50] and 1.06 [0.74-1.50] respectively. Results were unchanged among participants without diabetes or coronary heart disease. CONCLUSIONS: Within the limitations of this cross-sectional study we conclude that low-dose aspirin is not associated with prevalent periodontal status in a nationally representative sample of US adults.

The human papillomavirus (HPV) vaccine can prevent HPV-related oropharyngeal cancers. Dental practitioners are uniquely positioned to promote HPV vaccines during routine dental care but experience barriers to doing so. Qualitative interviews were conducted with dental practitioners to understand barriers and inform intervention strategies to promote HPV vaccines. Dental practitioners were invited to participate in phone interviews about knowledge, self-efficacy, and the fear of negative consequences related to HPV vaccine promotion as well as feedback on potential interventions to address these barriers. Interviews were audio recorded, transcribed, and analyzed using rapid qualitative analysis with a sort-and-sift matrix approach. Interviews were completed with 11 practitioners from six dental clinics (avg. 31 min). Though most thought HPV vaccination was important, they lacked detailed knowledge about when and to whom the vaccine should be recommended. This led to a hypothesized need for discussions of sexual history, feelings of limited self-efficacy to make the recommendation, and fear of patient concerns. Still, practitioners were supportive of additional training opportunities and provided input into specific interventions. The nuance of how these barriers were described by practitioners, as well as the possible solutions they identified, will help shape future interventions supporting HPV vaccine promotion in dental care.
RESUMEN
BACKGROUND: Preterm infants are at greater risk than term infants for physical and developmental disorders. Morbidity and mortality increases as gestational age at delivery decreases. Observational studies indicate an association between poor periodontal health and risk for preterm birth or low birthweight, making periodontitis a potentially modifiable risk factor for prematurity. AIM: To identify randomized controlled trials (RCTs) published between January 2011 and July 2012 and discuss all published RCTs testing whether periodontal therapy reduces rates of preterm birth and low birthweight. METHODS: Search of databases including PubMed, ISI Web of Science and Cochrane Library. RESULTS: The single RCT identified showed no significant effect of periodontal treatment on birth outcomes. DISCUSSION: All published trials included non-surgical periodontal therapy; only two included systemic antimicrobials as part of test therapy. The trials varied substantially in terms of sample size, obstetric histories of subjects, study preterm birth rates and the periodontal treatment response. The largest trials - also judged to be high-quality and at low risk of bias - have yielded consistent results, and indicate that treatment does not alter rates of adverse pregnancy outcomes. CONCLUSION: Non-surgical periodontal therapy, scaling and root planing, does not improve birth outcomes in pregnant women with periodontitis.

IMPORTANCE: Chronic periodontitis, a destructive inflammatory disorder of the supporting structures of the teeth, is prevalent in patients with diabetes. Limited evidence suggests that periodontal therapy may improve glycemic control. OBJECTIVE: To determine if nonsurgical periodontal treatment reduces levels of glycated hemoglobin (HbA1c) in persons with type 2 diabetes and moderate to advanced chronic periodontitis. DESIGN, SETTING, AND PARTICIPANTS: The Diabetes and Periodontal Therapy Trial (DPTT), a 6-month, single-masked, multicenter, randomized clinical trial. Participants had type 2 diabetes, were taking stable doses of medications, had HbA1c levels between 7% and less than 9%, and untreated chronic periodontitis. Five hundred fourteen participants were enrolled between November 2009 and March 2012 from diabetes and dental clinics and communities affiliated with 5 academic medical centers. INTERVENTIONS: The treatment group (n = 257) received scaling and root planing plus chlorhexidine oral rinse at baseline and supportive periodontal therapy at 3 and 6 months. The control group (n = 257) received no treatment for 6 months. MAIN OUTCOMES AND MEASURES: Difference in change in HbA1c level from baseline between groups at 6 months. Secondary outcomes included changes in probing pocket depths, clinical attachment loss, bleeding on probing, gingival index, fasting glucose level, and Homeostasis Model Assessment (HOMA2) score. RESULTS: Enrollment was stopped early because of futility. At 6 months, mean HbA1c levels in the periodontal therapy group increased 0.17% (SD, 1.0), compared with 0.11% (SD, 1.0) in the control group, with no significant difference between groups based on a linear regression model adjusting for clinical site (mean difference, -0.05% [95% CI, -0.23% to 0.12%]; P = .55). Periodontal measures improved in the treatment group compared with the control group at 6 months, with adjusted between-group differences of 0.28 mm (95% CI, 0.18 to 0.37) for probing depth, 0.25 mm (95% CI, 0.14 to 0.36) for clinical attachment loss, 13.1% (95% CI, 8.1% to 18.1%) for bleeding on probing, and 0.27 (95% CI, 0.17 to 0.37) for gingival index (P < .001 for all). CONCLUSIONS AND RELEVANCE: Nonsurgical periodontal therapy did not improve glycemic control in patients with type 2 diabetes and moderate to advanced chronic periodontitis. These findings do not support the use of nonsurgical periodontal treatment in patients with diabetes for the purpose of lowering levels of HbA1c. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00997178.

Bisphosphonates (BP), potent antresorptive agents, play a key role in managing osteolytic bone disorders including osteoporosis, Paget's disease, bone metastasis, and multiple myeloma. However, their long-term administration is associated with increased risk for bisphosphonate-related osteonecrosis of the jaw (BRONJ) development. At present, there is no curative therapy for BRONJ, and patients are often treated palliatively with antibiotics, antimicrobial mouth rinses, and debridement of necrotic bone. This article highlights a new treatment modality that may be beneficial to a subset of osteoporosis patients suffering from BRONJ. Here we report a BRONJ case that was initially unresponsive to conservative treatment, but subsequently responded to teriparatide (recombinant human PTH1-34) therapy.

INTRODUCTION: Periodontitis is a common oral disease associated with coronary artery disease (CAD), cerebrovascular disease (CBVD) and type 2 diabetes (T2D). We studied if periodontitis treatment improves clinical outcomes and reduces medical care costs in patients with CAD, CBVD or T2D. METHODS: We used clinic records and claims data from a health care system to identify patients with periodontitis and CAD, CBVD or T2D, and to assess periodontal treatments, hospitalizations, medical costs (total, inpatient, outpatient, pharmacy), glycated hemoglobin, cardiovascular events, and death following concurrent disease diagnoses. We compared clinical outcomes according to receipt of periodontal treatment and/or maintenance care in the follow-up period, and care costs according to treatment status within one year following concurrent disease diagnoses, while adjusting for covariates. The data were analyzed in 2019-21. RESULTS: We identified 9,503 individuals, 4,057 of whom were in the CAD cohort; 3,247 in the CBVD cohort; and 4,879 in the T2D cohort. Patients who were selected and elected to receive treatment and maintenance care were less likely to be hospitalized than untreated individuals (CAD: OR = 0.71 (95% CI: 0.55, 0.92); CBVD: OR = 0.73 (0.56, 0.94); T2D: OR = 0.80 (0.64, 0.99)). Selection to treatment and/or maintenance care was not significantly associated with cardiovascular events, mortality, or glycated hemoglobin change. Total care costs did not differ significantly between treated and untreated groups over 4 years. Treated patients experienced lower inpatient costs but higher pharmacy costs. CONCLUSIONS: Patients with periodontitis and CAD, CBVD or T2D who were selected and elected to undergo periodontal treatment or maintenance care had lower rates of hospitalizations, but did not differ significantly from untreated individuals in terms of clinical outcomes or total medical care costs.

AIMS: Infection may be a rheumatoid arthritis (RA) risk factor. We examined whether signs of periodontal infection were associated with RA development in the First National Health and Nutrition Examination Survey and its epidemiological follow-up study. MATERIAL AND METHODS: In 1971-1974, 9702 men and women aged 25-74 were enrolled and surveyed longitudinally (1982, 1986, 1987, 1992). Periodontal infection was defined by baseline tooth loss or clinical evidence of periodontal disease. Baseline (n = 138) and incident (n = 433) RA cases were defined via self-report physician diagnosis, joint pain/swelling, ICD-9 codes (714.0-714.9), death certificates and/or RA hospitalization. RESULTS: Adjusted odds ratios (ORs) (95% CI) for prevalent RA in gingivitis and periodontitis (versus healthy) were 1.09 (0.57, 2.10) and 1.85 (0.95, 3.63); incident RA ORs were 1.32 (0.85, 2.06) and 1.00 (0.68, 1.48). The ORs for prevalent RA among participants missing 5-8, 9-14, 15-31 or 32 teeth (versus 0-4 teeth) were 1.74 (1.03, 2.95), 1.82 (0.81, 4.10), 1.45 (0.62, 3.41) and 1.30 (0.48, 3.53); ORs for incident RA were 1.12 (0.77, 1.64), 1.67 (1.12, 2.48), 1.40 (0.85, 2.33) and 1.22 (0.75, 2.00). Dose-responsiveness was enhanced among never smokers. The rate of death or loss-to-follow-up after 1982 was two- to fourfold higher among participants with periodontitis or missing ≥9 teeth (versus healthy participants). CONCLUSIONS: Although participants with periodontal disease or ≥5 missing teeth experienced higher odds of prevalent/incident RA, most ORs were non-statistically significant and lacked dose-responsiveness. Differential RA ascertainment bias complicated the interpretation of these data.

BACKGROUND: Maternal periodontal disease has been associated with an increased risk of preterm birth and low birth weight. We studied the effect of nonsurgical periodontal treatment on preterm birth. METHODS: We randomly assigned women between 13 and 17 weeks of gestation to undergo scaling and root planing either before 21 weeks (413 patients in the treatment group) or after delivery (410 patients in the control group). Patients in the treatment group also underwent monthly tooth polishing and received instruction in oral hygiene. The gestational age at the end of pregnancy was the prespecified primary outcome. Secondary outcomes were birth weight and the proportion of infants who were small for gestational age. RESULTS: In the follow-up analysis, preterm birth (before 37 weeks of gestation) occurred in 49 of 407 women (12.0%) in the treatment group (resulting in 44 live births) and in 52 of 405 women (12.8%) in the control group (resulting in 38 live births). Although periodontal treatment improved periodontitis measures (P<0.001), it did not significantly alter the risk of preterm delivery (P=0.70; hazard ratio for treatment group vs. control group, 0.93; 95% confidence interval [CI], 0.63 to 1.37). There were no significant differences between the treatment and control groups in birth weight (3239 g vs. 3258 g, P=0.64) or in the rate of delivery of infants that were small for gestational age (12.7% vs. 12.3%; odds ratio, 1.04; 95% CI, 0.68 to 1.58). There were 5 spontaneous abortions or stillbirths in the treatment group, as compared with 14 in the control group (P=0.08). CONCLUSIONS: Treatment of periodontitis in pregnant women improves periodontal disease and is safe but does not significantly alter rates of preterm birth, low birth weight, or fetal growth restriction. (ClinicalTrials.gov number, NCT00066131 [ClinicalTrials.gov].).

AIM: Determine whether periodontitis progression during pregnancy is associated with adverse birth outcomes. METHODS: We used clinical data and birth outcomes from the Obstetrics and Periodontal Therapy Study, in which randomly selected women received periodontal treatment before 21 weeks of gestation (N=413) or after delivery (410). Birth outcomes were available for 812 women and follow-up periodontal data for 722, including 75 whose pregnancies ended <37 weeks. Periodontitis progression was defined as >or=3 mm loss of clinical attachment. Birth outcomes were compared between non-progressing and progressing groups using the log rank and t tests, separately in all women and in untreated controls. RESULTS: The distribution of gestational age at the end of pregnancy (p>0.1) and mean birthweight (3295 versus 3184 g, p=0.11) did not differ significantly between women with and without disease progression. Gestational age and birthweight were not associated with change from baseline in percentage of tooth sites with bleeding on probing or between those who did versus did not progress according to a published definition of disease progression (p>0.05). CONCLUSIONS: In these women with periodontitis and within this study's limitations, disease progression was not associated with an increased risk for delivering a pre-term or a low birthweight infant.

BACKGROUND: Periodontitis is associated with glycemic control in patients with diabetes. The purpose of this study was to determine if glycosylated hemoglobin is elevated in patients with periodontitis who have not been diagnosed with diabetes. METHODS: Glycosylated hemoglobin (HbA1c) was assessed using a chairside test in 59 adults without diabetes but with periodontitis (having at least five teeth with probing depth [PD] > or =5 mm, bleeding on probing [BOP], and clinical attachment or radiographic bone loss) and 53 healthy controls (PDs < or =4 mm and BOP < or =15%). Groups were compared using the t test and linear regression. Patients with HbA1c levels > or =6% were compared using the Fisher exact test and logistic regression. RESULTS: Periodontitis cases were more likely than controls to be male (68% versus 38%; P = 0.002) and current or former smokers (P = 0.002). Cases had significantly higher body mass index (BMI) than controls (27.6 kg/m(2) versus 25.5 kg/m(2); P = 0.018) but were of similar age (51.3 years versus 50.9 years; P = 0.89). Unadjusted mean HbA1c levels did not differ significantly between cases and controls (5.66% +/- 0.56% versus 5.51% +/- 0.44%; P = 0.12). After adjustments for age, gender, BMI, and current smoking, mean HbA1c was significantly higher in cases (between-group difference, 0.21%; P = 0.046). A higher proportion of cases (27.3%) than controls (13.2%) had HbA1c values > or =6%, although this difference was not statistically significant (P >0.1). CONCLUSIONS: Periodontitis is associated with a slight elevation in glycosylated hemoglobin. The clinical significance of this difference remains to be determined. This preliminary finding is consistent with earlier reports that periodontitis is associated with elevated blood glucose in adults without diabetes and may increase one's risk for type 2 diabetes.

BACKGROUND: Our previous studies reported on the obstetric, periodontal, and microbiologic outcomes of women participating in the Obstetrics and Periodontal Therapy (OPT) Study. This article describes the systemic antibody responses to selected periodontal bacteria in the same patients. METHODS: Serum samples, obtained from pregnant women at baseline (13 to 16 weeks; 6 days of gestation) and 29 to 32 weeks, were analyzed by enzyme-linked immunosorbent assay for serum immunoglobulin G (IgG) antibody to Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans), Campylobacter rectus, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia (previously T. forsythensis), and Treponema denticola. RESULTS: At baseline, women who delivered live preterm infants had significantly lower total serum levels of IgG antibody to the panel of periodontal pathogens (P = 0.0018), to P. gingivalis (P = 0.0013), and to F. nucleatum (P = 0.0200) than women who delivered at term. These differences were not significant at 29 to 32 weeks. Changes in IgG levels between baseline and 29 to 32 weeks were not associated with preterm birth when adjusted for treatment group, clinical center, race, or age. In addition, delivery of low birth weight infants was not associated with levels of antibody at baseline or with antibody changes during pregnancy. CONCLUSIONS: Live preterm birth is associated with decreased levels of IgG antibody to periodontal pathogens in women with periodontitis when assessed during the second trimester. Changes in IgG antibody during pregnancy are not associated with birth outcomes.

PURPOSE: To report the clinical features, risk factors, management, and treatment outcomes of nitrogen-containing bisphosphonate (n-BIS)-related osteonecrosis of the jaw (BRONJ). PATIENTS AND METHODS: Patients with suspected BRONJ were referred to the School of Dentistry for evaluation and treatment. RESULTS: A total of 26 patients (9 men and 17 women, mean age 64 years) were diagnosed with BRONJ. Of the 26 patients, 23 had received n-BIS therapy for cancer and 3 for osteoporosis. BRONJ lesions were noted more frequently in the mandible and in the posterior sextants. Of the 26 patients, 16 had developed BRONJ after dentoalveolar procedures, and 10 had developed it spontaneously. The mean interval to development of BRONJ was shorter in the patients with cancer receiving intravenous n-BIS than in the patients with osteoporosis receiving oral n-BIS (37.1 versus 77.7 months, P = .02). Using the American Association of Oral and Maxillofacial Surgeons staging system, 2 patients were diagnosed with stage I lesions, 19 with stage II, and 5 with stage III lesions. The initial management of BRONJ was nonsurgical, with debridement performed at subsequent visits, if needed. The BRONJ lesions healed completely in 4 patients, healed partially in 8, remained stable in 7, and progressed in 7. The spontaneous lesions responded favorably to BRONJ management compared with lesions that developed after dentoalveolar procedures (P = .01). No significant difference was found in response to BRONJ management between patients who had continued or discontinued n-BIS therapy after the BRONJ diagnosis (P = .54). CONCLUSIONS: Long-term n-BIS therapy and recent dental procedures are consistent findings in patients with BRONJ. Spontaneous BRONJ lesions respond favorably to current BRONJ treatment strategies.

BACKGROUND: A recent clinical trial (Obstetrics and Periodontal Therapy [OPT] Study) demonstrated that periodontal therapy during pregnancy improved periodontal outcomes but failed to impact preterm birth. The present study evaluated seven target bacteria, Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans), Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia (previously T. forsythensis), Prevotella intermedia, Campylobacter rectus, and Fusobacterium nucleatum, in subgingival dental plaque of pregnant women in the OPT Study and their association with birth outcomes. METHODS: Pregnant women were randomly assigned to receive periodontal treatment before 21 weeks' gestation or after delivery. Subgingival plaque was sampled at baseline (13 to 16 weeks; 6 days of gestation) and at 29 to 32 weeks. We analyzed subgingival plaque samples from women who experienced fetal loss, delivered a live preterm infant (preterm women), or delivered a full-term infant (full-term women). Samples were analyzed using quantitative polymerase chain reaction. Associations between preterm birth and bacterial counts and percentages were tested using multiple linear regression. RESULTS: No significant differences were observed at baseline between preterm and full-term women for any measured bacterial species or group of species, after accounting for multiple comparisons. Changes in bacterial counts and proportions during pregnancy also were not associated with birth outcomes. In full-term and preterm women, periodontal therapy significantly reduced (P <0.01) counts of all target species except for A. actinomycetemcomitans. CONCLUSIONS: In pregnant women with periodontitis, non-surgical periodontal therapy significantly reduced levels of periodontal pathogens. Baseline levels of selected periodontal pathogens or changes in these bacteria resulting from therapy were not associated with preterm birth.

BACKGROUND: Although clinicians generally consider it safe to provide dental care for pregnant women, supporting clinical trial evidence is lacking. This study compares safety outcomes from a trial in which pregnant women received scaling and root planing and other dental treatments. METHODS: The authors randomly assigned 823 women with periodontitis to receive scaling and root planing, either at 13 to 21 weeks' gestation or up to three months after delivery. They evaluated all subjects for essential dental treatment (EDT) needs, defined as the presence of moderate-to-severe caries or fractured or abscessed teeth; 351 women received complete EDT at 13 to 21 weeks' gestation. The authors used Fisher exact test and a propensity-score adjustment to compare rates of serious adverse events, spontaneous abortions/stillbirths, fetal/congenital anomalies and preterm deliveries (<37 weeks' gestation) between groups, according to the provision of periodontal treatment and EDT. RESULTS: Rates of adverse outcomes did not differ significantly (P> .05) between women who received EDT and those who did not require this treatment, or between groups that received both EDT and periodontal treatment, either EDT or periodontal treatment alone, or no treatment. Use of topical or local anesthetics during root planing also was not associated with an increased risk of experiencing adverse outcomes. CONCLUSIONS: EDT in pregnant women at 13 to 21 weeks' gestation was not associated with an increased risk of experiencing serious medical adverse events or adverse pregnancy outcomes. Data from larger studies and from groups with other treatment needs are needed to confirm the safety of dental care in pregnant women. CLINICAL IMPLICATIONS: This study provides evidence that EDT and use of topical and local anesthetics are safe in pregnant women at 13 to 21 weeks' gestation.
