Periodontitis and Helicobacter pylori Infection: Eradication and Periodontal Therapy Combination.

Objectives This study was aimed to assess (1) the prevalence of salivary and gastric Helicobacter pylori (HP) infection in patients with and without periodontitis, (2) the prevalence of HP infection in patients with periodontitis according to its clinical classification, (3) the effect of periodontitis treatment in patients with or without gastric HP infection, and (4) if gastric HP eradication in combination with periodontitis treatment influences periodontitis clinical outcome. Materials and Methods Thirty-three adults with periodontitis treated by quadrant scaling and root planning (QSRP). The simplified plaque index (PI), bleeding on probing index (BOP), probing pocket depth (PPD), and clinical attachment level (CAL) were assessed pretreatment and 3 months of posttreatment. The patients were tested for oral and gastric HP. Gastric HP (+) patients received eradication therapy. A control group of 32 periodontically healthy volunteers was tested for oral and gastric HP. Saliva samples were evaluated by real-time polymerase chain reaction (rtPCR); gastric HP was detected by urea breath test (UBT). Statistical Analysis Normality of variables assessed by the Kolmogorov–Smirnov test, while the differences of pre- and post-treatment were analyzed by paired samples t -test. Differences between subgroups were compared by a Student’s t -test or a Mann–Whitney U -test. Comparisons of nominal variables were made by Pearson’s Chi-square test. Results No saliva samples were positive for HP. Gastric HP was detected in six patients with periodontitis and seven controls ( p > 0.05). HP infection affected patients with higher disease stages and grades. All HP (+) patients underwent successful eradication treatment. All clinical periodontitis indices improved following QSRP. HP (+) patients who received QSRP as adjunctive to eradication treatment showed improvement in BOP ( p < 0.001), PI ( p < 0.013), and CAL ( p < 0.004) compared with HP (−) patients who received QSRP alone. Conclusion Periodontitis was not associated with gastric HP infection. Saliva was not a gastric HP supply reservoir. Gastric HP infection was associated with advanced stages and grades of periodontitis. Although all periodontal clinical markers improved after QSRP, BOP, PI, and CAL, they were further improved when combined with eradication treatment. Periodontal evaluation and treatment combined with HP eradication are recommended in patients with HP gastric infection.

Evaluation of antibacterial efficacy of Triphala toothwipes on oral Streptococcus mutans count in intellectually disabled children.

To evaluate antibacterial efficacy of Triphala toothwipes on oral Streptococcus mutans counts in intellectually disabled (ID) children. Twenty-seven children with a mild ID were randomly divided into two groups: A - Triphala and B - placebo group. Toothwipes were given to caregivers of children belonging to the respective groups, and were instructed to use them 1h after their meals, twice a day for 7days. Simplified Plaque index was recorded and plaque samples were collected for microbiological examination at baseline, 48h, and 7days. The obtained data were tabulated and analyzed. Triphala group showed a statistically significant reduction of S. mutans after 48h and 7days. Both Triphala and placebo groups showed a statistically significant reduction in dental plaque after 48h and 7days. Triphala toothwipes are effective against the oral S. mutans compared with placebo toothwipes, while both the toothwipes are equally effective in reducing dental plaque. Thus, Triphala toothwipes can be used as an adjunct aid along with routine oral hygiene practices in individuals who lack psychomotor skills or are dependent on others to maintain oral hygiene, including infants, preschoolers, geriatric population, and children with special health care needs.

Prevalence of dental caries among 6 - 12 year old schoolchildren in social marginated zones of Valencia, Spain.

BackgroundTo estimate the prevalence of caries and to study oral health habits (oral hygiene, toothbrushing frequency, cariogenic or no cariogenic diet, visits to dentist) in children aged 6 to 12 with social exclusion risk. Material and MethodsA cross sectional study was conducted in a sample of 160 children aged form 6 to 12 years belonging to Colegio Madre Petra in Torrent and Colegio Nuestra Señora de los Desamparados in Nazaret (Valencia). Among other variables DMFT and Greene and Vermilion simplified plaque index were analyzed. ResultsThe prevalence of caries observed was 81.87% and the global DMFT was 4.481. The mean plaque index observed was 1.12. No statistically significant differences were found between global DMFT and sex, global DMFT and age, global DMFT and diet, global DMFT and visits to the dentist and global DMFT and plaque index. A significant association was seen between global DMFT and ethnicity and global DMFT and brushing frequency. Statistically significant association was found also between plaque index and visits to the dentist and plaque index and diet. ConclusionsIt was observed that children at risk of social exclusion had a very high global DMFT and a regular plaque index. So, it can be concluded that social exclusion constitute an underlying factor that increase caries prevalence and global DMFT and a marker of poor oral hygiene habits. Key words:Dental caries, caries prevalence, oral hygiene habits, plaque index, toothbrushing frequency, social exclusion.

Auricular Acupressure Improves Habit Reversal Treatment for Nail Biting.

Nail biting leads to a variety of health issues. Habit reversal treatment is a major approach to cease nail biting, but is often ineffective since patients continue to suffer from anxiety, a major trigger. This study investigated whether the potential anxiety relief provided by auricular acupressure could improve the efficacy of habit reversal treatment, as evidenced by improved stomatological and other outcomes. In a pragmatic, randomized, crossover, pilot clinical trial, 83 nail biters (8-12 years old) received habit reversal treatment in combination with either auricular acupressure intended to reduce anxiety (Method A) or placebo auricular acupressure (Method B). The alternative protocol was employed after a two-month washout period. The primary outcome measured was the 41-item child self-reported version of the Screen for Child Anxiety Related Emotional Disorders, while the secondary outcomes were the nail growth status (NS), which represented the fingernail growth of each finger during habit reversal treatment, simplified plaque index (SPI), and the simplified gingival index (SGI) as measures of oral health. A paired sample t-test was used to assess the differences between Methods A and B, and the differences in the anxiety scores, NS, SGI, and SPI between the baseline and each time point. Forty-one children successfully completed both arms of the treatments and attended all appointments. There were significant differences in the efficacy of habit reversal treatment, the anxiety score, the nail status, and the SGI in favor of Method A (p < 0.001). Auricular acupressure appears to improve the efficacy of habit reversal treatment, likely by reducing anxiety.

Salivary levels of cariogenic bacterial species during orthodontic treatment with thermoplastic aligners or fixed appliances: a prospective cohort study

BackgroundFixed orthodontic appliances might be associated with intraoral adverse effects on enamel, due to plaque accumulation and their colonization by oral microbes. At the same time, the demand for esthetic alternatives to orthodontic treatment, like thermoplastic aligners, is growing. However, thermoplastic aligners may behave differently intraorally than fixed appliances in terms of bacterial colonization and biofilm formation. Therefore, the aim of this prospective cohort study was to assess the salivary prevalence of the cariogenic bacteria Streptococcus mutans, Lactobacillus acidophilus, and Streptococcus sanguinis among adolescents treated orthodontically with thermoplastic aligners or fixed appliances.MethodsThirty adolescent patients (17 girls/13 boys; mean age 13.8 years old) were assigned to treatment with either (i) self-ligating fixed appliances with nickel-titanium archwires or (ii) aligners constructed from clear transparent polyethylenterephthalat-glycol copolyester (PET-G) thermoplastic sheets. Whole stimulated saliva was collected from each patient at three time points: at baseline (before bonding and initiation of orthodontic therapy or before insertion of the thermoplastic aligners), after 2 weeks, and after 1 month. A simplified plaque index, a simplified gingival index, and the decayed, missing, and filled teeth (DMFT) index were assessed from the clinical examination of the patients. Microbiological analysis of salivary bacteria was performed by quantitative polymerase chain reaction, followed by descriptive and inferential statistics at the 5% level.ResultsAlthough patients treated with aligners had significantly lower plaque and gingivitis scores throughout treatment compared to patients treated with fixed appliances, no significant difference could be found between the S. mutans counts of the two groups at any time through treatment (P > 0.05). On the other hand, patients treated with aligners had significantly lower salivary S. sanguinis counts at all time points than patients treated with fixed appliances (P < 0.05). Finally, almost no L. acidophilus were identified in the collected saliva samples in either of the treated samples.ConclusionsWithin the limitations of this study, there were no differences in the salivary counts of S. mutans or L. acidophilus among adolescent patients treated for 1 month with thermoplastic aligners or self-ligating appliances. On the other hand, patients treated with aligners had lower salivary levels of S. sanguinis compared to those treated with self-ligating appliances.

Oral health status in children with inherited dystrophic epidermolysis bullosa

Background/Aim. Epidermolysis bullosa is a group of rare, genetic connective tissue diseases that cause blisters in the skin and mucosal membranes. The aim of this study was to evaluate the oral health status of patients with epidermolysis bullosa dystrophica and level of knowledge and opinion of parents about the implementation of preventive measaures and quality of dental care of affected children. Methods. This study included a group of 17 patients from Serbia suffering from dystrophic epidermolysis bullosa and matched control group. Dental caries status was assessed using the Klein-Palmer index. Oral hygiene status was verified with oral hygiene indices, simplified plaque index, and calculus index as described by Green and Vermillion. The gingiva was assessed as healthy or inflamed (gingivitis) on the basis of any changes in color, shape, size and surface texture. The condition of oral mucosa has been registered on the basis of inspection of the lips, tongue, a floor of the mouth, mouth vestibule and palate. The level of knowledge and the impressions of parents about the application of preventive measures were investigated through two questionnaires specifically designed for this study. Results. In both dentitions, there was the highest percentage of caries teeth. In primary dentition average value of the modified plaque index was 1.4 ? 1.14 and modified calculus was 0.7 ? 1. On permanent teeth average plaque index was 2 ? 0.4, and average calculus 1.6 ? 0.6. Statistically, significant higher values were found in permanent dentition in percentage distribution of decayed, missing, filled teeth and also for plaque and calculus indices between affected children and the control group. Most common findings on mucosa were microstomia (76.5%) and ankyloglossia (88.2%). Conclusion. The absence of protocol between the treating physician and the dentist and not sufficiently informed parents are leading to inadequate dental care. The implementation of preventive measures is of most importance to decrease the risk of severe complications that are difficult to be managed.

Periodontal disease detection in primary and mixed dentitions.

This was to compare the periodontal status of children with primary and mixed dentition at the time of their first consultation. Children (200), aged 0-12years (156 with mixed and 44 with primary dentition), were examined by assessing their simplified plaque index (PI) and simplified periodontal record (PSR). Statistical analysis (Chi-square test) was performed with appropriate software to find any significant associations between sex, type of dentition and PI with the PSR codes (0, 1, 2, 3 and 4). There was no statistically significant difference with regard to gender (p=0.82). Generalised PI was associated more significantly with mixed dentition (p=0.025 and higher PSR scores (p<0.001). There was no significant relationship between sex and PSR codes (p=0.82). Children presenting with a mixed dentition had worse PI values and PSR scores. It is important to perform periodontal examination in children to diagnose and prevent future periodontal disease and maintain their dentition as well as to identify any associated systemic conditions.

Oral Health and Blood Pressure: The IPC Cohort

Chronic periodontal diseases involve bacteria-induced inflammation of the tissues supporting the teeth. An inflammatory origin for hypertension has been proposed, and periodontal diseases are associated with an increased risk of vascular disease. The present study was performed to assess whether oral health conditions were associated with the risk of hypertension in adult population. The sample comprised 102,330 subjects, who underwent medical and oral examinations between 2002 and 2011. A full-mouth clinical examination was performed using simplified plaque index, calculus index, and simplified modified gingival index to assess dental plaque, dental calculus and gingival inflammation. The number of teeth was recorded. Biological parameters, including blood pressure were assessed. A subset analysis according to age (<65 or ≥65 years) was conducted. The association between blood pressure and oral conditions was explored using a logistic regression approach. In the sample of subject ≥65 years, no significant association was found between oral variables and the risk of hypertension. In subset <65 years, oral variables and risk of hypertension were associated. Insufficient masticatory function and missing teeth (>10) showed odds ratio (OR) = 1.20 [95% CI = 1.08-1.32] and OR = 1.17 [95% CI = 1.04-1.31], respectively. Hypertension was also associated with high level of dental plaque [OR = 1.90, 95% CI = 1.55-2.33], dental calculus [OR = 1.18, 95% CI = 1.07-1.29] and gingival inflammation [OR = 1.56, 95% CI = 1.35-1.80] Moreover, in this subset <65 years, the risk of hypertension increases with the number of dental exposure. The present study indicates that insufficient masticatory function, poor oral hygiene, and oral inflammation are associated with hypertension in subject <65.

Estimation of changes in C-reactive protein level and pregnancy outcome after nonsurgical supportive periodontal therapy in women affected with periodontitis in a rural set up of India.

Aims and Objectives:Estimation of changes in C-reactive protein (CRP) level and pregnancy outcome after nonsurgical supportive periodontal therapy in pregnant women affected with Periodontitis.Materials and Methods:A total of 100 pregnant females with periodontitis were assigned to treatment and control groups. All the details about previous and current pregnancies were obtained. Full-mouth periodontal examination was done at baseline, which included oral hygiene index simplified plaque index, gingival index, and clinical attachment loss. CRP level was also measured from collected blood sample initially at baseline and later after the delivery in both the group. Subjects in the treatment group received nonsurgical periodontal treatment during the second trimester of gestational period, and those in the control group did not receive any periodontal therapy during this period. Periodontal therapy included mechanical plaque control instructions and scaling and root planning. Outcome measures assessed were changes in CRP levels, gestational age, and birth weight of the infants. When delivery occurred at <37 weeks of gestation, it was considered as preterm birth (PTB), and low birth weight (LBW) was recorded when the infant weighed <2500 g.Results:In the treatment group, 32% of PTB and 68% of Normal term birth (NTB) delivery whereas in the control group 72% PTB and 28% of NTB were recorded. Infants measured with LBW were 36% in the treatment group and 52% in the control group. Mean birth weight was 2644.44 ± 450.53 g in the treatment group and 2447.82 ± 368.02 g in the control group (P < 0.05). Mean gestational age in the treatment group was 35.57 ± 2.40 weeks and 34.17 ± 2.92 weeks in the control group (P < 0.05). The treatment group showed statistically significant reduction in mean values of CRP level after delivery in comparison to baseline values (P < 0.05), whereas control group showed no significant reduction in values (P > 0.05).Conclusion:Nonsurgical supportive periodontal therapy may lower the risk of preterm delivery in females affected with periodontitis by reducing CRP level.
