The traditional occlusal indicators used in dental practice are articulation papers, shim-stock foils, elastomeric impression materials, and occlusal wax strips. These static dental materials have been widely believed to have occlusal force descriptive capability. However, modern material studies are challenging the widespread belief that occlusal indicator materials can measure differing occlusal force levels. This chapter evaluates the force reporting limitations of these static occlusal indicators and discusses how clinicians subjectively interpret their appearance characteristics to determine differing occlusal force levels. This chapter then compares these non-digital occlusal indicators to computerized occlusal analysis technology that records and displays precise, quantifiable, relative occlusal force variances and occlusal contact timing sequences. This digital data aids the clinician in making a more accurate occlusal analysis and can guide the clinician in the correction of occlusal contact force and timing abnormalities, thereby eliminating the subjectivity that is inherent in traditional occlusal indicator use.

This chapter further details the diagnostic occlusal capabilities of the T-Scan's digital force and timing data, by presenting two separate studies that compared measured closure and excursive occlusal contact force and timing parameters in orthodontic and non-orthodontic young adults. A commentary is included regarding the clinical pitfalls of using maximally invasive, subjective interpretation to choose occlusal contacts for treatment instead of employing minimally invasive, computer-guided occlusal contact selection. This last section clearly illustrates to the reader that both patients and dentists will markedly benefit from the implementation of occlusal measurement technology.

This chapter introduces the Air Indexing method for detecting and quantifying cervical dentin hypersensitivity as a companion to the T-Scan Occlusal Analysis System, which evaluates occlusal force and timing values of contacting teeth. The chapter discusses detection, diagnosis, and treatment of clinical signs and/or symptoms of Cervical Dentin Hypersensitivity (CDH). A 17-year-long retrospective study conducted between 1979 and 1996 is presented that illustrates the correlation between Cervical Dentin Hypersensitivity and its resolution following occlusal adjustment. Resulting stress from occlusal contact force is etiologic for non-carious cervical lesion formation and root degradation. This chapter details how biocorrosion and lost protective glycoproteins hasten the effects of applied force, creating CDH symptoms and cervical abfractions. Lastly, the Air Indexing method of CDH diagnosis is melded with T-Scan occlusal analysis to diagnose and treat CDH symptoms. Together, these two methods yield more CDH/occlusal insight than either method can alone.

The relative occlusal force and real-time occlusal contact timing data provided by the T-Scan technology can be used to manage the insertion occlusal force design of implant prostheses, as their long-term survivability is tied directly to their installed occlusal function. This chapter discusses how in daily dental practice clinicians spend a great deal of time making corrective occlusal adjustments using solely articulating paper as their intended guide. However, current research shows that articulating paper markings do not measure occlusal force, such that implant occlusal force control is compromised, which can lead to peri-implant tissue loss, breakage of implant restorative components, and de-osseointegration. However, by using the T-Scan technology, the clinician eliminates the subjectivity involved in using articulating paper ensuring the occlusal design of newly installed implant prostheses are optimal improving prosthesis longevity. Examples are presented of how T-Scan force and time data can aid in implant restoration occlusal force control.

There are many steps in fabrication of dental crowns and bridges at which an error can occur, and a technician can only fabricate a quality restoration if the impression itself is of adequate quality. All dental practitioners should have the ability to evaluate the quality of dental impression before sending to the laboratory. Elastomeric silicones (polysiloxane) are the most utilised impression materials in dental practice. The present study deal with the deficiencies of silicones dental impressions sent to commercial dental laboratories for fabrication of single crowns and bridges.

This study analyzes international historical trends in the use of different types of materials in dental practice. The author describes the chemical properties of their ingredients and the potential and observed adverse effects in patients and dental technicians resulting from clinical or occupational exposure to various metals like beryllium, used to produce metal alloys. The growing use of various products (resin cements, ionomer cements, aesthetic restorative materials, resins, endodontal cements, and others) based on the compound bisphenol-A, whose chemical structure is similar to that of estrogen. Considering the demographic and contemporary work force characteristics of those involved in dental practice in the Brazil, the study highlights the possible effect of the use of these materials in both male and female patients and all age strata, as well as in health professionals with occupational exposure to products containing bisphenol-A.

<p>Wood is an old – modern material, It was and still used in a wide range in a various purposes as construction, decoration and remains the most popular material all over the world, The research provides an overview of the role of  timber as an important heritage element which forms the main characters and distinguishes features of many historical buildings in Islamic architecture and used widely in many applications, it had been played a great role in construction and structure of buildings, besides that it had been used in a beautiful purpose in different places whether indoors or outdoors use<strong> </strong>. The research presents the case studies of historical timber in different types of building in Islamic architecture which constructed from more than 1400 years ago, although the historical timber in old buildings exposed to many disasters and faced quite numbers of problems as a result of natural phenomena, man-made, humidity, and termites but it still stands proudly as a great sustain materials. The research shows how he use of timber in historical buildings as sources of inspiration and living evidence of ways of sustainable building practices the types of deterioration which appeared clearly an effect on the statue of historical timber, for that the research introduces some recommendations in the light of ICOMOS international charter “ <a href="http://www.icomos.org/en/home/179-articles-en-francais/ressources/charters-and-standards/163-principles-for-the-preservation-of-historic-timber-structures">Principles for the Preservation of Historic Timber Structures</a> 1999” that Emphasizes the necessity of taking a serious steps and clear strategy to save our heritage elements</p>
