They are composed of sodium, potassium, calcium, magnesium, aluminum, silicon, phosphorus, zirconium, and titanium. Structurally, dental ceramics contain a crystal phase and a glass phase based on the silica structure, characterized by silica tetrahedra, containing central Si4+ ion with four O− ions. Biocompatibility, esthetics, durability, and easier customization properties have led to the increased usage of ceramics. The specialty of ceramic teeth is its ability to mimic the natural tooth in color and translucency along with its strength. Ceramics have excellent intraoral stability and wear resistance adding to their durability. Basically, the inorganic composition of teeth and bones are ceramics which is hydroxyapatite. Over the past few years, the technological evolution of ceramics for dental applications has been incredible, as new materials and processing techniques are being introduced. The improvement in strength, as well as toughness, has made it possible to expand the range of indications to long-span fixed partial prostheses, implant abutments, and implants. While porcelain-based materials are still a major component in dental science, there have been moves to replace metal ceramics systems with all-ceramic systems. Numerous all-ceramics are being developed which is highly esthetic, biocompatible to tissue, and long-lasting in nature. Advances in computer-aided design/computer-aided manufacturing technologies have led to immense popularity of high-strength ceramic materials. These materials are highly esthetic, biocompatible to tissue, and long-lasting in nature. In this review, we will discuss all-ceramic materials which are used in dentistry.","PeriodicalId":220601,"journal":{"name":"The Saint′s International Dental Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130530647","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}

Materials and Methods: Two hundred and fifty patients of varying age and sex, requiring at least extraction of two teeth, were picked from the outpatient department of oral and maxillofacial surgery. In each patient, two teeth were extracted under local anesthesia, one under xylocaine plain and other under xylocaine with adrenaline. Time of onset, depth, and duration of analgesia were recorded. Conclusion: Lidocaine with epinephrine (1:200,000) local anesthesia efficacy in dental extractions is more effective than lidocaine without adrenaline in extraction of tooth, and the onset, duration, and depth of analgesia of xylocaine hydrochloride with adrenaline were good as compared to plain xylocaine (xylocaine without adrenaline). Thus, lignocaine as a local anesthetic may be an effective drug in dental extractions with the higher safety margin.","PeriodicalId":220601,"journal":{"name":"The Saint′s International Dental Journal","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133651009","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}

Various anatomic landmarks are used to determine this missing component of occlusion which is lost with the loss of teeth. However, variation has been observed in the orientation of occlusal plane determined clinically with different anatomical landmarks as references. Objective: This study was undertaken to determine the relation of intraoral anatomic soft tissue landmarks, namely, retromolar pad and parotid papilla with occlusal plane in natural dentition. Materials and Methods: Irreversible hydrocolloid impressions of 100 edentulous individuals (50 males and 50 females) were made to get the models. A 16 gauge wire was extended from mandibular occlusion plane posteriorly up to retromolar pad to establish their relationship. Furthermore, vertical distance of apex of parotid papilla to maxillary molar cusp tip it opposed (distobuccal cusp of maxillary first molar or mesiobuccal cusp of maxillary second molar), and mandibular molar cusp tip (to which parotid papilla apposed) was measured when the teeth were in maximal intercuspal position. Results: This study determined that the natural occlusal plane is oriented posteriorly at the level corresponding with the lower third of retromolar pad. Mean distance of parotid papilla above the corresponding maxillary cusp tip (while in occlusion) was 5.048 mm, and mean distance of Parotid papilla above the corresponding mandibular molar cusp tip (while in occlusion) was determined to be 3.602 mm. The difference in observed means between males and females or between right and left side was not statistically significant.","PeriodicalId":220601,"journal":{"name":"The Saint′s International Dental Journal","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114831989","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}

Aims: This in vitro study compared the retention of three prefabricated overdenture posts cemented with self-adhesive resin cement. Subjects and Methods: Thirty freshly extracted noncarious, healthy mandibular canines were sectioned 1 mm above cementoenamel junction and endodontically treated. The teeth were divided in three groups and prepared for overdenture posts: Group 1: Access post overdenture (EDS, USA), Group 2: Flexi overdenture post (EDS, USA), and Group 3: Ceka Preci-Clix overdenture (Ceka Preci-line, Germany). Posts were cemented with self-adhesive resin cement (Relyx U 100, Germany). Each tooth was positioned identically in the universal testing machine (Instron), and the amount of force necessary to remove a post from the tooth was recorded. Statistical Analysis Used: The results obtained were statistically analyzed using one-way analysis of variance and the comparisons of groups were performed using post hoc Tukey honestly significant difference test. Results: Ceka Preci-Clix overdenture post has maximum mean retention value of 171.57N and access post overdenture has minimum retention value of 98.75N. Conclusions: Ceka Preci-Clix overdenture post was more retentive (171.57) due to its parallel sided design than the other posts used in this study. Flexi overdenture post, due to its split shank threaded design, was the 2 nd most retentive post (128.88) after Ceka Preci-Clix overdenture post and access post overdenture were least retentive post (98.75) due to its thick-walled hollow design.","PeriodicalId":220601,"journal":{"name":"The Saint′s International Dental Journal","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122087525","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}
