Palatal Vault Depth Influence on the Flexural Strength of Two Heat Cure Acrylic Denture Base Resins: An in vitro Study
Authors: Reddy B Madan Mohan , Himabindu M , Padmaja B Indira , Sunil M , Reddy N Raja 
Published: May 2014

ABSTRACT
Complete dentures often fracture during normal masticatory function. The reason could be due to the shape of the palate, i.e. deep, medium or shallow palatal vault. This in vitro study was performed to determine the relationship of palatal vault depth and flexural strength of two different permanent denture base resins. Edentulous maxillary casts of patients were collected from the department of prosthodontics, among these the cast with the deepest palatal vault was selected. The specimens were then subjected for flexural strength on universal testing machine. The results revealed that the denture bases fabricated on medium palatal vault depth were best in the flexural strength and denture bases on shallow palatal vault depth faired the least. Among the resins the denture bases fabricated using high impact heat cure resin, were better than the denture bases fabricated using regular heat cure resin. All these results were statistically significant except the results between the regular heat cure denture bases and high impact heat cure denture bases fabricated on the deep palatal vault depth. Also the comparison of fracture energies of denture bases fabricated on deep palatal vault with high impact heat cure resin to denture bases fabricated on medium and shallow palatal vaults with high impact heat cure resin were not significant. It was also observed that all the specimens have fractured in the midline.

Clinical implications
Palatal vault depth significantly affected the flexural strength of heat cure resin. The most frequent mechanical failure of heat cure resin is fracture especially at the midline. The denture bases fabricated using high impact heat cure resin had best flexural strength than the denture bases fabricated using regular heat cure resin which reduced the fractures.

Published: May 2014

ABSTRACT
There is disagreement about the association between missing teeth and the presence of temporomandibular disorder (TMD).

Aim
To investigate whether, the span of edentulousness, gender, number of quadrants involved, pathological migration and the type of kennedy's classification are related to the temporomandibular joint (TMJ) dysfunction signs.

Materials and methods
Clinical examination of 250 patients (males 99 and females 151) was done among the age group of 35 to 45 years. The patients were partially edentulous for 6 months or more and did not wear any kind of prosthesis.

Results
Among 250 subjects, females showed more TMJ dysfunction signs. Clicking sounds were present in 46.5%, mandibular deviation was present in 40% of individuals, TMJ tenderness was observed in 32% and masseter was involved in 32% of individual. Temporomandibular joint dysfunction signs in relation to pathologic migration of teeth show that clicking and mandibular deviation was present in 54.5 and 49.2% and among muscles masseter muscle tenderness 41.9% was more commonly present. Masseter muscle tenderness 64.1% was seen in individuals who were edentulous for more than 5 years.

Conclusion
Females subjects had a significantly higher prevalence of TMJ dysfunction signs then male subjects. As the span and time of edentulousness, the number of missing teeth and the number of quadrant involved increased, the signs of dysfunction became more prevalent. Among the TMJ dysfunction signs deviation and clicking sound were most frequently observed. The masseter muscle was most commonly affected and demonstrated muscle tenderness.

Published: May 2014

ABSTRACT

Objective
To determine the denture hygiene habits in complete denture patients according to their age and time of dentures.

Methods
In this study a self administered structured was developed to know the attitude of the patients regarding denture hygiene in the department of Prosthodontics. The total study sample consisted of 230 subjects including 124 (53.9%) males and 106 (46.1%) females. Data was analyzed using SPSS version 15.0 with chi-square test at p-value <0.05.

Results
Nearly half of the subjects clean their dentures daily once. Participants from the younger age group and who had been wearing dentures since 2 years maintain better frequency of cleaning. The majority of these subjects used water and brush for denture cleansing. After seeing the condition, half of the dentures were rated as good 50.3%, followed by fair and poor as 29.5 and 20.2% respectively.

Clinical significance
Poor condition of complete dentures seen in the population is mainly due to irregularly cleansing habits and also less usage of cleansing solutions. Dentists should give proper instructions regarding maintenance of denture hygiene.

Published: May 2014

ABSTRACT

Objectives
To determine and correlate the effect of clomiphene citrate, Letrozole in women undergoing infertility treatment on the gingival inflammatory status.

Materials and Methods
The present study is a randomized controlled clinical trial which consisted of 26 women using CC for three menstrual cycles, 26 women using CC for more than three cycles, 26 women using Letrozole. All subjects were clinically examined for plaque levels (Plaque Index), gingival inflammation, bleeding on probing (Gingival Index, Sulcus Bleeding Index). Scaling was done to all patients and all periodontal parameters were reassessed 1 month after scaling. The results were compared with a control group of 26 women matched for age, educational status and professional level, and oral habits and who had never used ovulation drugs.

Results
Baseline scores of all the test groups showed higher amount of plaque levels and inflammation compared to control. (p < 0.05). After scaling a significant reduction in inflammation was observed in all the test groups along with the control group (p < 0.0001), but women using the drugs showed persistence of inflammation compared to control (p < 0.01).

Conclusion
It can be concluded from the present study that the presence of elevated levels of hormones due to the effect of ovulation induction drugs may be the reason for the gingival inflammation in test groups.

The Relationship between prosthetic status and the Geriatric Oral Health Assessment Index in a Group of Institutionalized elderly of an Indian City: A cross-sectional study
Authors: Bijle Mohammed Nadeem Ahmed , Shetty Vittal Das 
Published: May 2014

ABSTRACT

Aim
To assess and compare the quality of life and oral health status among institutionalized elderly in Pune.

Materials and methods
A cross-sectional, quantitative exploratory study was conducted in persons 60 years of age in an institutionalized elderly home. The GOHAI questionnaire was completed by a single examiner, who interviewed the patients in their local language. The oral examination was carried out according to WHO oral health survey using the DMFT-index, community periodontal index (CPI), periodontal loss of attachment (PLA), prosthetic use, and needs according to criteria established by the WHO by a calibrated examiner. Descriptive analysis was carried out using absolute and relative frequencies of the qualitative variables and means with respective standard deviations for the quantitative variables. The Student's t-test was applied to compare groups.

Results
Out of the total 110 individuals interviewed for the study, 64% were males and 36% were females. Individuals with up to 20 missing teeth and individuals with more than 20 missing teeth were 20 and 80% respectively. Based on the prosthetic need, 66% individuals needed replacement of teeth by dentures in one or both arches while 34% did not need any replacement by complete denture. The mean value for physical dimension was 5.40 whereas for psychosocial dimension, pain/discomfort and behavioral dimension were 8.02, 4.58 and 7.32.

Conclusion
The quality of life was found to be more favorable in individuals with less than 20 teeth missing. The quality of life among complete denture wearers in both the arches was better as compared to the quality of life among nondenture wearers. Prosthetic replacement by complete denture helps the individuals to maintain better oral health.

Clinical significance
The data obtained from the present study may serve as a reference point for comparisons of the magnitude of quality-of-life indicators relating to oral health.

Calcifying Odontogenic Cyst: A Rare Report of A Nonneoplastic Variant associated with Cholesterol Granuloma
Authors: Aparna Manikkath , Gupta Mukund , Kamath Abhay , Solomon Monica , Pai Keerthilatha , Radhakrishnan Raghu 
Published: May 2014

ABSTRACT

Aim
To report a case of a non-neoplastic variant of calcifying odontogenic cyst (COC) with the lining epithelium showing ameloblastomatous proliferation and capsule exhibiting features of a cholesterol granuloma. The importance of delineating this histologic variant from unicystic ameloblastoma and the formation of cholesterol granuloma in this variant is discussed.

Background
Calcifying odontogenic cyst is a developmental jaw cyst, which presents itself as both the neoplastic and the non-neoplastic forms. The ameloblastomatous variant of COC is often mistaken for unicystic ameloblastoma and treated aggressively.

Case report
A 68-year-old female who presented with a cystic enlargement of the posterior mandible on the right side was suggestive of unicystic ameloblastoma based on radiography and initial biopsy report. Microscopic examination of the excision specimen, however, was fitting in favor of calcifying odontogenic cyst with ameloblastomatous proliferation.

Conclusion
Identifying the non-neoplastic ameloblastomatous variant of COC from a cystic ameloblastoma is crucial as the treatment of the two lesions vary considerably.

Clinical significance
This case emphasizes the need for thorough examination of the entire surgical specimen before arriving at an appropriate diagnosis.

C-Arm Fluoroscopy: A Reliable Modality for Retrieval of Foreign Bodies in the Maxillofacial Region
Authors: Pandyan Deepak , Nandakumar N , Qayyumi Burhanuddin N 
Published: May 2014

ABSTRACT
The anatomic complexity of the maxillofacial region makes the retrieval of foreign bodies a daunting task for the maxillofacial Surgeon. Moreover the inability of 2-dimensional imaging to precisely locate foreign bodies makes it challenging. The anatomic proximity of critical structures and esthetic considerations limits the access and thus poses a greater challenge for the surgeon in cases of foreign body retrieval. Hereby we propose a simple technique and a case report to support, the retrieval of small (<5 mm greatest dimension) objects from the maxillofacial region. The present technique uses a 2 dimensional mobile C arm Fluoroscopy and a needle triangulation method to precisely locate a loosened miniplate screw in the mandibular angle region.

ABSTRACTAimThe present review aims to discuss the last 10 years published data on the topic of the use of osseointegrated implants in diabetic subjects, particularly regarding the influence of antibiotics administration in the perioperative period.BackgroundIn the last decades, oral rehabilitation significantly has evolved particularly with the use of osseointegrated implants. Increased life expectation of population is reflecting in a greater number of diabetic patients who might require dental osseointegrated implants rehabilitation. Diabetes was considered for a long time as a contraindication for oral implant placement. In this context, the use of antibiotics is still a controversial factor when we correlate it to implant success rate.Review resultsAlthough 228 articles were initially selected for evaluation of proposed criteria, only 16 articles were considered valid. Among the 16 selected articles, only six articles represented clinical research that discussed the influence of the antibiotic in the success of osseointegration of dental implants in diabetic subjects. Five were retrospective studies and one a prospective research.ConclusionData favors the use of antibiotics without significant side effects but clinical investigations of the need of prophylaxis antibiotic or therapeutic antibiotics are still scarce. The lack of adequate methodology is one of the main problems of the current articles. It is important to emphasize that studies should present detailed methodology in order to allow reproducibility.Clinical significancePermanent tooth loss is a pathological condition that affects millions of people worldwide. The possibility of successful treatment of edentulous areas through osseointegrated implants in those systemic compromised patients is a matter of scientific discussion. Although antimicrobial agents must be used rationally and carefully to avoid development of bacterial resistance, more studies are needed in order to support evidence regarding the influence of antibiotics in the success of dental implant surgery in diabetic patients.How to cite this articleBorba AM, Souza DFM, Brozoski MA, Burim RA, da Graça Naclério-Homem M, Deboni MCZ.

IntroductionVitamin D insufficiency (VDI) has been associated with increased cardiovascular risk in the non‐HIV population. This study evaluates the relationship among serum 25‐hydroxyvitamin D [25(OH)D] levels, cardiovascular risk factors, adipokines, antiviral therapy (ART) and subclinical atherosclerosis in HIV‐infected males.MethodsA cross‐sectional study in ambulatory care was made in non‐diabetic patients living with HIV. VDI was defined as 25(OH)D serum levels <75 nmol/L. Fasting lipids, glucose, inflammatory markers (tumour necrosis factor‐α, interleukin‐6, high‐sensitivity C‐reactive protein) and endothelial markers (plasminogen activator inhibitor‐1, or PAI‐I) were measured. The common carotid artery intima‐media thickness (C‐IMT) was determined. A multivariate logistic regression analysis was made to identify factors associated with the presence of VDI, while multivariate linear regression analysis was used to identify factors associated with common C‐IMT.ResultsEighty‐nine patients were included (age 42±8 years), 18.9% were in CDC (US Centers for Disease Control and Prevention) stage C and 75 were on ART. VDI was associated with ART exposure, sedentary lifestyle, higher triglycerides levels and PAI‐I. In univariate analysis, VDI was associated with greater common C‐IMT. The multivariate linear regression model, adjusted by confounding factors, revealed an independent association between common C‐IMT and patient age, time of exposure to protease inhibitors (PIs) and impaired fasting glucose (IFG). In contrast, there were no independent associations between common C‐IMT and VDI or inflammatory and endothelial markers.ConclusionsVDI was not independently associated with subclinical atherosclerosis in non‐diabetic males living with HIV. Older age, a longer exposure to PIs, and IFG were independent factors associated with common C‐IMT in this population.

Authors: Goepp Julius , Fowler Elizabeth , Mcbride Teresa , Landis Darryl 
Published: May 2014

Primary Study Objective: Determine the frequency of abnormal fecal biomarker test results in patients with 13 irritable bowel syndrome (IBS)—related ICD-9 (International Statistical Classification of Diseases and Related Health Problems) codes. Study Design: Quantitative review of de-identified records from patients in whom IBS was a possible diagnosis. Methods: Records were selected for analysis if they included any of 13 IBS-related diagnostic codes and laboratory test results of fecal testing for all biomarkers of interest. Data collection was restricted to one 12-month period. Frequency distributions were calculated to identify rates of abnormal results for each biomarker within the total number of tests conducted in the eligible population. Results: Two thousand, two hundred fifty-six records were included in the study, of which 1867 (82.8%) included at least one abnormal value. Quantitative stool culture for beneficial bacteria (Lactobacillus and Bifidobacterium) indicated low growth suggestive of intestinal dysbiosis in 73.1% of records, followed by abnormally elevated eosinophil protein X (suggestive of food allergy) in 14.3%, elevated calprotectin (suggestive of inflammation) in 12.1%, detection of parasites in 7.5%, and low pancreatic elastase (suggestive of exocrine pancreatic insufficiency) in 7.1%. Conclusions: Abnormal fecal biomarkers are prevalent in patients with diagnoses suggestive of IBS. Abnormal fecal biomarker testing, if confirmed in additional independent clinical trials, could substantially reduce the economic costs associated with diagnosis and management of IBS.

Published: May 2014

Primary Study Objective: To evaluate the economic utility of a fecal biomarker panel structured to suggest alternative, treatable diagnoses in patients with symptoms of irritable bowel syndrome (IBS) by quantifying, comparing, and contrasting health service costs between tested and non-tested patients. Study Design: Retrospective, matched cohort study comparing direct medical costs for IBS patients undergoing fecal biomarker testing with those of matched control subjects. Methods: We examined de-identified medical and pharmacy claims of a large American pharmacy benefit manager to identify plan members who underwent panel testing, were eligible for covered benefits for at least 180 days prior to the test date, and had data available for 30, 90, and 365 days after that date. We used propensity score matching to develop population-based control cohorts for each tested cohort, comprised of records with IBS-related diagnoses but for which panel testing was not performed. Primary outcome measures were diagnostic and medical services costs as determined from claims data. Results: Two hundred nine records from tested subjects met inclusion criteria. The only significant baseline differences between groups were laboratory costs, which were significantly higher in each tested cohort. At each follow-up time point, total medical and gastrointestinal procedural costs were significantly higher in non-tested cohorts. Within tested cohorts, costs declined significantly from baseline, while costs rose significantly in non-tested control cohorts; these differences were also significant between groups at each time point. Conclusions: Structured fecal biomarker panel testing was associated with significantly lower medical and gastrointestinal procedural costs in this study of patients with IBS symptoms.
In-vitro developmental studies of Cheilanthes farinosa (Forssk.) Kaulf. (Pteridaceae)
Authors: Srivastava Ruchi , Uniyal Prem Lal 
Published: May 2014

Developmental pattern of spore germination, gametophyte growth, differentiation, sex ontogeny and development of
sporophytes of Cheilanthes farinosa were studied in in-vitro conditions. The spore germination and prothallial development are found to be of Vittaria type and Ceratopteris type, respectively. The species seems be a good colonizer in nature. A considerable numbers of sporophytes were produced through intra- and intergametophytic selfing in culture. Sporophyte
production efficiency was observed to be 8% in isolate population and 12% in composite gametophyte population.
Genetic barriers and over-exploitation for ornamental purposes causes the reduction in the population size. Protection of this taxon in the natural habitat is urgently required as it grows well in barren and disturbed habitats and help in the establishment of colonies of other plants.
