To evaluate the effect of saliva contamination on the shear bond strength of a new two-step self-etch adhesive (P90 system adhesive) to dentin and to determine the effect of contaminant removing treatments on the recovery of bond strengths.The buccal surfaces of 40 human premolars were ground to expose dentin. The specimens were randomly divided into four groups. Group 1 is uncontaminated and serves as the control group. Further groups were divided based on the step in the bonding sequence when the contamination had occurred as follows: Group 2 (primer, saliva contamination, rinse and dry), group 3 (after procedure of group 2, reapplication of primer), and group 4 (after procedure like in control group, saliva contamination, rinse and dry). Filtek P90 composite resin cylinders of 3 mm diameter and 3 mm length were fabricated on the surfaces. Shear bond strength testing was done in an Instron Universal Testing Machine and the data were subjected to one-way analysis of variance (ANOVA) and Students t-test.With P90 system adhesive, group 2 and group 4 showed lower shear bond strength than group 1 (control) and group 3 (P < 0.05).Saliva contamination significantly decreased the shear bond strength of the adhesive to dentin.

Thyroid carcinoma represents less than 1% of all cancers. The first line of treatment for thyroid cancer is partial/total thyroidectomy. High-dose Iodine(131) therapy using Iodine radioisotopes is commonly used in patients with well differentiated thyroid carcinoma after total thyroidectomy. In this process, the non-thyroidal tissues, such as, salivary gland, stomach and breast tissues also take up radioactive iodine. Salivary gland scintigraphy is widely accepted as a sensitive and valid method for evaluation of salivary gland dysfunction after Radioactive Iodine(131) Therapy (RIT).To assess and compare the salivary flow rates, relative uptake and ejection fractions in parotid and submandibular glands just before and one month after Iodine(131) therapy.The study was conducted on 24 patients diagnosed with well differentiated thyroid carcinoma who underwent partial/total thyroidectomy and were due for radioactive iodine therapy. These patients were divided into two groups based on the lesion based dosimetry (Group A: 60-100Gy; Group B: 100-150Gy). Salivary gland assessment was done by salivary gland scintigraphy before and after RIT.The data collected was tabulated and statistically analysed using SPSS software version16 using paired t-test and individual sample t-test.A statistically significant difference in the uptake percent and ejection fraction percent in the parotid and submandibular glands before RIT and one month after RIT was observed in the study.We inferred from the study that there was an overall decrease in uptake percent and ejection fraction percent one month post RIT in both parotid and submandibular glands. Also, a statistically significant difference was noted in the uptake and ejection fraction percent between Group A and Group B concluding the fact that the damage is dose related.

Space analysis quantifies the amount of crowding within the arches estimating the severity of space discrepancy. The space gaining procedures include extraction and non-extraction procedures like expansion, proximal stripping and molar distalization.To identify features seen in molar distalization cases.The sample size comprised 20 patients in whom molar distalization was decided as the treatment plan. The study models and lateral cephalograms of all the patients were taken. Occlusograms were obtained. Model analysis and cephalometric analysis were performed. Descriptive statistical analysis like mean, standard deviation, standard error and mode were done.The parameters in Question gave following results. The Bolton analysis showed anterior mandibular excess with mean value of 1.56mm1.07. The first order discrepancy between maxillary central and lateral incisors was 51.95. The premolar rotation showed mean value of 16.585.12. The molar rotation showed the value of 7.662.26. The nasolabial angle showed the mean of 101.258.7 IMPA of 101.45.74.The six features studied in molar distalization cases [First order discrepancy between upper central and lateral incisors; Rotation of premolars and molars; Boltons discrepancy in anterior dentition; Average to horizontal growth pattern; Proclined lower incisors and Obtuse nasolabial angle] can be taken as patterns seen in molar distalization cases and considered as a valid treatment plan.

Fluoride is a double edged sword. The assessment of dental caries and fluorosis in endemic fluoride areas will facilitate in assessing the relation between fluoride concentrations in water with dental caries, dental fluorosis simultaneously.The objective of the following study is to assess the dental caries and dental fluorosis prevalence among 12 and 15-year-old school children in Nalgonda district, Andhra Pradesh, India.This was a cross-sectional study. Two stage cluster sampling technique was employed to select 20 schools from Nalgonda district. The oral examination of available 12 and 15-year-old children fulfilling the inclusion and exclusion criteria was carried out to assess dental caries and fluorosis. The examination was conducted by a single trained and calibrated examiner using the mouth mirror and community periodontal index probe under natural daylight. These areas were divided into four categories, low, medium, high and very high fluoride areas based on the fluoride concentration at the time of statistical analysis. The data was analyzed using Statistical Package for the Social Sciences version 16 (IBM, Chicago, USA).The caries prevalence was less among 12-year-old children (39.9% [369/924]) compared with 15-years-old children (46.7% [444/951]). The prevalence was more among females (50.4% [492/977]) than males (35.8% [321/898]). The prevalence was more in low fluoride area (60.5% [300/496]) followed by very high fluoride area (54.8% [201/367]), high fluoride area (32.4% [293/904]) and medium fluoride area (17.6% [19/108]) in the descending order. The fluorosis prevalence increased with increasing fluoride concentration with no difference in gender and age distribution.Low fluoride areas require fluoridation or alternate sources of fluoride, whereas high fluoride areas require defluoridation. Defluoridation of water is an immediate requirement in areas with fluoride concentration of 4 parts per million and above as dental fluorosis is a public health problem in these areas with 100% prevalence.

Langerhans Cells (LCs) are dendritic cells of the oral epithelium which play a role in a series of oral lesions from gingivitis to oral cancer. Oral Lichen Planus (OLP) is an oral mucosal T-lymphocyte mediated immunologic reaction to an unidentified putative antigen or allergen.The aim of this study was to quantify the presence of immature LCs in OLP comparing them with normal epithelium.A retrospective study using 30 of OLP cases were conducted. Immunohistochemistry was performed using polyclonal anti-CD1a antibodies to identify LCs in 10 cases of normal tissue and 30 samples of OLP. The distribution of LCs among lesional tissue and normal mucosa was analysed using Mann-Whitney U test.LC population in OLP was significantly higher when compared to the normal epithelium (p<0.001).The increase in LCs indicates the active role played during the antigen detection in OLP and subsequent presentation to T-lymphocytes.

Though great strides have been taken globally in the fight against oral diseases, problems persist especially among poor, disadvantaged and socially marginalised communities like tribes. Konda Reddies are one of the most primitive tribes of Bhadrachalam who because of their isolation, inaccessibility to dental resources and lack of dental knowledge follow traditional methods of oral hygiene practices, which are found to be inadequate to maintain oral health.To assess the periodontal status of Konda reddy tribes residing in Bhadrachalam of Khammam district, India.Based on availability and accessibility the tribes were gathered using convenient sampling method. The total study population consisted of 500 subjects. Using a preformed Performa the oral hygiene practices and periodontal status was recorded using CPI index.The total study population was 500, comprising of 225 males and 275 females in the age group ranging from 20- >70 years. The mean number of sextants with healthy condition were 0.040.19; calculus 4.691.21; pockets 4-5 mm 0.910.91 and pockets >6mm 0.020.15.Poor oral hygiene and periodontal status was seen among the tribes. Under these circumstances, the implementation of a basic oral health care programme for these tribes is a high priority.

The study was performed to investigate the prevalence, morphology and calcification pattern of elongated styloid process in Saudi population of Aseer (Southern) region and its relation to gender and sub-age groups.This study was analyzed digital panoramic radiographs of 1,162 adults. Any radiograph with questionable styloid process was excluded from the study. The apparent length of the styloid process was measured by a single experienced dental and maxillofacial Radiologist. The elongated styloid process was classified with the radiographic appearance based on the morphology and calcification pattern. The data were analyzed by using Students t-test and Chi-square test with P value less than 0.05.A total of 1,085 Digital panoramic radiographs showed elongated styloid process of which 686 (63.2%) were noticed in males and 399 (36.8%) were noticed in female patients. There was a statistical significant difference noticed in the mean difference of elongated styloid process between 20-29, 50-59 and 60 years and above sub-age groups. The elongated styloid process was more prevalent in elderly aged male patients (P < 0.05). Type I morphology with calcified out line (a) was the most frequent pattern of calcification noticed in the present study.The panoramic radiographs are economical, easily accessible and useful diagnostic tool for early detection of elongated styloid process with or without symptoms. However, studies with larger sample size would further help to assess the prevalence of this elongated styloid process in Saudi population of various other regions.

To determine the demineralization inhibitory potential of fluoride varnish and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and to compare and evaluate the additive effect of fluoride varnish + CPP-ACP.Ten healthy premolar teeth that were extracted for orthodontic purposes were collected, and each tooth was longitudinally sectioned buccolingually and mesiodistally into four sections. The teeth were then assigned to four different treatment groups namely fluoride varnish, CPP-ACP, F(-) varnish followed by CPP-ACP and control. The prepared enamel samples were suspended in an artificial caries challenge for 10 days. The demineralizing inhibitory effects of the groups were recorded using polarized light microscopy.Statistical analysis was carried out using analysis of variance and Duncans multiple range tests.The mean lesion depths of all the groups were Group 1 (fluoride varnish): 104.71, Group 2 (CPP-ACP): 127.09, Group 3: (F(-) varnish + CPP-ACP): 82.34, Group 4 (control): 146.93.Demineralization inhibitory potential on the additive use of F(-) varnish and casein phosphopeptide was superior to fluoride varnish or CPP-ACP applied alone on the enamel of young permanent teeth.
