Association between preterm birth and low birth weight and maternal chronic periodontitis: A hospital-based case-control study.

BACKGROUND: Periodontal diseases (PDs) are one of the most common chronic diseases affecting overall oral functions, and their association with adverse pregnancy outcomes (APOs) has been an area of interest since the late 90s. OBJECTIVES: The present hospital-based case-control study aimed to find any association between maternal chronic periodontitis (CP) and preterm birth (PTB) and low birth weight (LBW) by comparing the periodontal parameters in patients with normal birth, PTB and LBW. MATERIAL AND METHODS: The participants of the study were females that had delivered a live baby (n = 1,200). They were classified as either cases or controls. The cases were defined as PTB if the delivery was before 37 weeks of gestation, and as LBW if the infant weighed <2,500 g. The others were controls. The intraoral examination, which included recording the periodontal status, was conducted within 3 days of delivery. Detailed medical history and demographic data were recorded for the determination of the confounding factors. The multivariable dependence of PTB and LBW on both the categorical and continuous data was analyzed using a multivariate logistic regression analysis. Adjusted odds ratios (AORs) with a 95% confidence interval (CI) for the risk of PTB and LBW were calculated. RESULTS: A strong association with PTB was found for a high plaque index (PI) score (AOR = 1.61; p < 0.001; 95% CI: 1.26-2.07) and a mean pocket probing depth (PPD) ≥4 mm (AOR: 4.32; p < 0.001; 95% CI: 3.09-6.02). A strong association with LBW was found for a high PI score (AOR = 2.02; p < 0.001; 95% CI: 1.43-2.83) and a mean PPD ≥4 mm (AOR: 8.70; p < 0.001; 95% CI: 6.01-12.59). A high PI score and a mean PPD ≥4 mm were independent risk factors for PTB and LBW. CONCLUSIONS: The presence of deep pockets and inadequate plaque control in pregnant females increased the risk of APOs.

Periodontal status and oral health behavior in hospitalized patients with chronic obstructive pulmonary disease.

AIM: We evaluated the periodontal health status and oral health behavior among hospitalized patients with chronic obstructive pulmonary disease (COPD) to assess the association of COPD with dental health. MATERIALS AND METHODS: A group of 100 hospitalized patients with COPD and a group of 100 age, sex, and race-matched control patients were included in this study. Detailed case histories along with standardized measures of oral health including gingival index, plaque index (PI), and simplified oral hygiene index (OHI) were estimated and compared. Probing depths and clinical attachment levels (CALs) were recorded at four sites per tooth. C-reactive protein (CRP) levels in saliva and serum were also measured. RESULTS: The study subjects had similar demographics and distribution in either group. Patients with COPD had significantly lower brushing frequency, poor periodontal health (OHI and PI), greater gingival inflammation, and deeper pockets/CALs compared to controls. Further COPD patients had significantly higher serum and salivary CRP levels compared to control groups. CONCLUSIONS: Lower brushing frequency, poor oral health, and presence of destructive periodontal disease were observed among patients with COPD, which warrants promoting dental care and oral health knowledge as an integrated approach to treating COPD patients.

An evaluation of 0.2% hyaluronic acid gel (Gengigel ®) in the treatment of gingivitis: a clinical & microbiological study.

AIM: Hyaluronic acid is a glycosaminoglycan with anti-inflammatory & anti edematous properties. This study is seeking to ascertain whether Hyaluronic acid gel formulation is clinically and microscopically effective in treatment of gingivitis. METHODS: In longitudinal, randomized, and placebo-controlled clinical trial, 105 patients with chronic plaque induce gingivitis were randomly divided into three groups; negative control group, placebo control group and test group. Patients were instructed to apply gel on inflamed gingiva twice daily in addition with routine oral hygiene maintenance. The clinical parameters Plaque Index (PI), Gingival Index(GI) and Papilla Bleeding Index (PBI) were determined at intervals of 1 week, 2 weeks and 4 weeks from baseline, microbiological parameters were monitored at the interval of 4 weeks from baseline. RESULTS: An improvement of all clinical variables was observed (p<0.05) for all treatment modalities. Clinically, There is significant difference (p<0.05) for GI & PBI in test group as compared to other groups, but reduction in PI was non-significant. In negative control and placebo control groups, the difference between clinical parameters was non-significant. Statistically significant (p<0.05) reduction in percentage of anaerobic gram negative bacilli and relative increase of gram positive coccoid cells was seen in all treatment groups at 4 weeks as compared to baseline. However, results were not statistically significant (p>0.05) in pair wise comparison in between groups. CONCLUSION: Local application of 0.2 % HA gel adjunct to non surgical periodontal treatment provided a significant improvement in clinical parameters than placebo control and negative control groups. Microbiologically experimental group does not showed any spastically significant results.

Papillon-lefevre syndrome: Case series and review of literature.

Papillon-lefevre syndrome (PLS) belongs to a heterogeneous group of skin diseases that are characterized by hyperkeratosis of palms and soles. It is a type IV palmoplantar keratosis (PPK) while the palmoplantar keratodermas share some features of PPK, they are etiologically heterogeneous. PLS differs from other types of PPK by the presence of severe and early onset periodontitis. Genetic studies have shown that mutation in the major gene locus of chromosome 11q14 with the loss of function of cathepsin-C (CTSC) gene is responsible for PLS. CTSC gene mutations are causative for PLS. The resultant loss of CTSC function is responsible for the severe periodontal destruction seen clinically. This report represents two siblings with classical signs and symptoms of PLS.

A double blind controlled trial comparing three treatment modalities for dentin hypersensitivity

Aim: This randomized, double blind, split mouth study was aimed to compare three dentin desensitizing treatment modalities. Methods: Two hundred sixty teeth of 25 patients; each having at least 2 hypersensitive teeth in each quadrant, were included. Teeth were randomized to 4 groups: Group A treated with 2% NaF solution, Group B received GLUMA®; an aqueous solution of Hydroxy-Ethyl-Methacrylate and Glutarldehyde, (HEMA-G), Group C received iontophoresis with distilled water (placebo) and Group D was treated with NaF-iontophoresis. Pain response was evaluated on a visual analogue scale (VAS), by using tactile, air blast and cold-water stimuli at 0-day, 15-day, 1-month and 3-months interval. Results: All treatments were effective in reducing dentinal hypersensitivity significantly, Group D and Group B were more effective than Group A and Group C at all time intervals. Group D and Group B were equally effective in reducing dentinal hypersensitivity at 15-day and 1-month interval but Group D was more effective at 3-months. Conclusion: All treatment modalities were more effective in reducing hypersensitivity than placebo. 2% NaF-iontophoresis and HEMA-G were more effective than 2% NaF local application at all time intervals. But at 3-months, 2% NaF-iontophoresis was more effective than HEMA-G, while placebo produced no significant effect in reduction of hypersensitivity (AU)
