It is usually a part of a syndrome and seldom occurs as an isolated entity. Genes responsible for non syndromic oligodontia are found to be MSX1 and PAX9 genes. \u0000Methods: Karyotyping was done taking sample from peripheral blood. Cytogenetic chromosome analysis revealed a normal male karyotype (46, XY) without any structural or numerical chromosome abnormalities. Hand wrists, clavicles, vertebral skeleton, skull and chest were found to be normal on radiological examination. After excluding other possible differential factors, the final diagnosis of non-syndromic Oligodontia was made. Preliminary impressions were made using impression compound and was molded on the edentulous ridge. Custom trays were fabricated and border molding was done using green stick impression compound and secondary impressions were made using zinc oxide eugenol impression paste. After maxillo-mandibular jaw relations, dentures were processed through compression molding technique. Dentures were inserted and the patient was taught about the insertion and removal of the dentures. Post insertion instructions regarding denture wear, functions of speech, mastication, hygiene and maintenance were given to the patient and the parent. \u0000Results: The patient was using prosthesis and happy with it during one year follow up. The rehabilitation with removable dentures at current age and later with osseo-integrated implants served as a satisfactory treatment outcome in such patients. \u0000Conclusion: This case report presents prosthodontic rehabilitation of a rare case of non-syndromic oligodontia in a 7-year old male patient with agenesis of all permanent teeth except the maxillary central incisors.","PeriodicalId":110010,"journal":{"name":"JBR Journal of Interdisciplinary Medicine and Dental Science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126125339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is important to provide protection to the oral structures to prevent severe damage from reflex grinding, masticating, and gnawing. There are several appliances available for this necessary protection but these are often inaccessible in developing countries due to various reasons, such as lack of availability or financial constraints. Sports mouth guards, which reduce the chance of shock, concussions, and other injuries as a result of high impact collisions and blows during athletic competition, are inexpensive and widely available in these developing countries. A simple mouth guard can be constructed from these pre-existing mouth guards which would be sufficient to provide the needed support for the aforementioned oral structures during seizure events. This case report presents a mouth guard fabricated from inexpensive sports mouth guards, specifically to prevent trauma to the tongue and other oral structures during seizures in a comatose patient.","PeriodicalId":110010,"journal":{"name":"JBR Journal of Interdisciplinary Medicine and Dental Science","volume":"242 6-7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114047358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Periodontal bacteria, especially P. gingivalis aggregates platelets and forms thrombus. At the same time, secretions such as serotonin, various cytokines, and adhesion factors also appear in the blood. The characteristic of the arterial lesions are dependent on the age of the patient and the condition of the endothelial cells. In young patients, infectious incidents occur due to embolic mechanisms in Buerger disease or adhesion to the superficial veins valves in varicose veins. In aged patients, incidents result in adhesion in the proximal aorta, coronary arteries or large arteries.

To achieve clinical success with such restorations, it is of clinical importance to ensure good bonding between this restoration and tooth surface. Bonding to dentin is far more challenging. Bond between dentin and dentin bonding adhesives is greatly influenced by: (1) Surface condition of dentin (moist/dry); (2) Chemical nature of dentin bonding agents. The present study has been designed: (i) to study the effect of various conditions (moist/dry) of dentin on bonding with dentin bonding agents; (ii) to compare the strength achieved by dentin, bonding agent of different systems (water/acetone based). This study was conducted to evaluate the effect of tooth surface wetting on shear bond strength of composite. Freshly extracted central incisors were taken. Cavities were prepared in middle 1/3 of teeth. Teeth were divided in groups A,B,C depending on their surface treatment (wet, semi dry, dry surface) and again in to sub groups depending on whether they are treated water based or acetone based dentin bonding agents(scotch bond, prime bond NT, clear fil SE) . All the cavities in samples were filled with composite and light cured. Composite was debonded from teeth by Instron machine. Debonded samples were scanned and micro graphed under SEM. From the observations made, statistically analyzed and duly discussed, following conclusions are drawn: 1. Optimal water content is necessary for achieving good bonding between dentin and composite. 2. Water based dentin bonding agents, show maximum shear bond strength with dentin in dry conditions. 3. Acetone based dentin bonding agents show maximum shear bond strength with dentin in wet conditions. Overview of the results shows that moisture plays a vital role in bonding of composite with dentin. Optimal water should be present for better bonding of dentin with composite. If dentin is in dry stage, then water based dentin-bonding agents should be used as they produce best results in dry conditions and if dentin is in wet state then acetone based dentin-bonding agents should be used as they produce best results in wet conditions.","PeriodicalId":110010,"journal":{"name":"JBR Journal of Interdisciplinary Medicine and Dental Science","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124838367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodology: Thirty sound, single–rooted human bicuspids extracted for orthodontic purpose were used to measure the temperature rise inside the pulp chamber by using a needle probe, connected to thermocouple thermometer through the apical foramen. Ninety specimens of dental composites (Spectrum, Esthet X & Z250) were prepared by using special mold to determine the depth of cure of different light curing modes (Quartz tungsten halogen, Light emitted diode & soft start) by using the scraping method described by ISO standard for polymer –based filling restorative & luting materials. For the assessment of the degree of conversion, eighteen samples of dental composites were tested by the Fourier – transformed infrared spectrometry according to the standard baseline technique of Rueggeberg et al., 1990. Result and Conclusion: QTH light curing showed the highest temperature rise value, while the soft start gave the lowest values. Soft start light curing revealed the highest depth of cure values, while the QTH showed the lowest values among three curing modes. There were overall statistical significant differences in the depth of cure values among groups of different curing systems & types of dental composites. Soft start light curing system showed the highest degree of conversion and QTH had the lowest values. Esthet X dental composite gave the highest results of the degree of conversion while Z250 showed the lowest values.","PeriodicalId":110010,"journal":{"name":"JBR Journal of Interdisciplinary Medicine and Dental Science","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128913057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lower left central (LL1) and lower right central (LR1) incisors exhibited 6 mm and 5 mm lingual probing depth, 4mm and 3.5mm lingual recession respectively and localized radiographic bone loss in the mid-half of the roots. The treatment strategy consisted of removal of the tongue piercing, professional prophylaxis, oral hygiene instructions and an open-flap surgery of the lingual anterior region of the mandible with the application of enamel matrix derivative (EMD) and bone graft material. Results: At the 1-, 3- and 7-month recall visits, the patient’s oral hygiene has been improved, and the attachment loss appears to have stabilized.

Successful mucociliary clearance, which lies at the centre of this defence mechanism, involves the synchronized function of two structures, namely, the periciliary liquid layer and the mucus layer. The two structures have collectively been termed the ‘two phase airway surface liquid’ system. This system is kept hydrated through regulation of sodium and chloride transport. A well hydrated airway surface liquid that allows the periciliary liquid layer to extend over the height of the outstretched cilia keeping mucus away from the epithelia is considered to be essential for effective mucus clearance and sinonasal health. This mechanism assists in trapping and eliminating foreign particles and, together with antimicrobial peptides, maintains a sterile environment in the nasal and paranasal sinuses, which are continually exposed to microorganisms in the external environment. In diseases such as rhinosinusitis, the mucociliary clearance capacity is diminished; the first line of defence is disrupted allowing for bacterial invasion and infection. This manuscript explores the prospect of an alternative approach for the prophylaxis and primary management of rhinosinusitis based on the maintenance of a well hydrated airway surface liquid.","PeriodicalId":110010,"journal":{"name":"JBR Journal of Interdisciplinary Medicine and Dental Science","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127957331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
