When it comes to oral health care, dental students play a vital role in educating and promoting public oral health. It is found that the dental students project a positive attitude toward dental health.[1-3] To serve as leaders and positive models for the patients, friends, and family, it is important for the dental students to improve their oral health behavior.
Oral health can be defined as “a standard of health of oral and related a tissue that enable an individual to eat, speak and socialize without active disease, discomfort or embarrassment and which contributes to general well- being.” It is considered as an essential component of general health.
Presently it has been found that though periodontal diseases are preventable, they are one of the major chronic infections affecting the population with their prevalence constantly on the rise.
Formation of biofilm or dental plaque acts as the chief etiological factor for the occurrence of periodontal disease and proximal caries. This, however, can be prevented by effective bacterial plaque removal, with the mechanical method of plaque control serving as the most effective and the easiest method....
It is always said that a healthy mouth often leads to a healthy body. Systemic heath is always preceded by a good oral health.1 The self-consideration of the oral health, by teeth cleaning with the help of toothbrush, or with the use of biting sticks, prevents formation of the dental plaque and periodontal infection.2,3
The various methods used for the oral hygiene maintenance can be chemical or mechanical. Dentifrices and toothbrushes are widely used for cleaning teeth. The traditional use of chewing sticks for cleaning teeth is deeply rooted in the Islamic culture.4,5
For the use of chewing sticks, the sticks of various plants of approximately pencil size are taken and chewed on one end until it becomes frayed into a brush. This brush end is used for the teeth cleaning in a similar manner as that of use of a toothbrush. This method of brushing teeth with the help of sticks is called as chewing sticks or Miswak.4
Miswak (miswaak, Miswaki, misswak, meswak, sewak, mswaki, siwaki and siwak are the different syn- onyms used in various Arabic dialects and countries) is an Arabic word, which means a tooth cleaning stick. In English language, Miswak has been referred to as the “natural toothbrush.” In certain geographical regions...
arious materials have been used in direct restorations of pos- terior teeth, such as amalgam and composite resin.1 Despite their functional durability2, amalgam restorations have been questioned in recent years due to the incorporation of mer- cury.3,4 In addition, there is a shift toward minimally invasive management of carious lesions.5 And, that may not make

amalgam the material of choice for this approach due to the need to sacrifice non-carious tooth structure to promote the retention of amalgam restorations.1
Previously, composite materials have been regarded as not suitable for posterior restorations.6 And, that was reflected on teaching of such a subject in dental schools. In 1989, a world- wide survey noted that, posterior composite restorations were not taught in more than 90% of dental schools.7 That was attributed to concerns about the longevity and performance of the composite in posterior teeth8 Further surveys of North American and European dental schools carried out in 1998 showed limited and variant clinical experience in the placement of posterior composites among undergraduate students.9,10 However, that was...
had undergone extraction of 12, 28, and 36 5 years ago, Ketac‐Fill with 47 a year ago and composite lling on the buccal surface of 26 a year ago. He had no speci c or relevant medical history. The patient was thoroughly assessed with his diet history, which revealed high sugar consumption and between meal snacking. The patient had no history of brushing teeth, use of interdental aids or mouthwash which accounted to poor oral hygiene. The patient had a history of pipe smoking once a day. On intraoral examination, carious lesions were revealed with teeth number 17, 16, 15, 14, 13, 11, 21, 22, 23, 24, 25, 26, 27, 38, 37, 35, 34, 33, 41, 43, 44, 45, 46, 47. Generalized mild redness of the marginal gingiva and interdental papillae with no periodontal pockets were observed as shown in Figure 1. High plaque scores were recorded. Smile pro ling and thorough examination of occlusion were done. The patient presented with loss of esthetics; diastema, missing 12 and black color stains on anterior teeth due to caries. Occlusion showed cross bite in mandibular left region, missing 36, mesial tilting of 37, and supraeruption of 15. There were no temporomandibular joint abnormalities detected. On soft tissue examination, nicotinic stomatitis was seen in palate area which can be attributed to his pipe smoking habit. Pretreatment photographs, diagnostic cast model workups, necessary radiographs which included orthopantomogram and full mouth series of X‐rays were...
Endodontic treatment of teeth with pulpal involvement results in considerable loss of tooth structure, and tooth weakness.1 In addition reduced availability of remaining tooth structure makes the task of restoration further challenging. Root posts are used to provide retention for the core materials, which are predictably delivered with contemporary resin composites.2,3 Therefore, the mechanical and physical properties of the buildup core material critically affects the successful clinical performance of restored endodontic teeth.4

llers frequently contain Zr particles, known to enhance the biocompatibility, durability and mechanical properties of resin composites.8,9 Zr is an exceptionally stable and durable material, with excellent biocompatibility and mechanical properties.9 Zr llers in bulk ll resin composites have been recently introduced in the form of ZirconCore (Harvard Dental International, GmbH, Hoppegarten, Germany) for core build up purpose in endodontically treated teeth. It is observed through laboratory based studies, that Zr nano particle containing restorative composite resins have shown better compressive strengths in comparison to silica and barium based micro and macro- lled composites.6
Recently, it was reported that Zr nano-particle ller containing bulk ll composite build up materials show higher compressive strength values as compared to conventional bulk ll materials.10 Therefore,...
Modern dentalceramic is the esthetic material of choice and has contributed greatly to the increased demand on cosmetic indirect restorations. Adhesive cementation of glass-ceramic restorations with a composite resin of optimum physical properties can withstand higher masticatory forces and has demonstrated improved clinical performance1. Bonding of indirect ceramic restorations to tooth structure involves the luting agent to interact with two different surfaces i.e. enamel/dentin and ceramic. As compared to other ceramics lithium disilicateceramics offer enhanced flexural

strength and fracture toughness2. Some investigators, due to improved mechanical properties, have also used LD ceramics for 3 unit bridges3,4.
As conditioning of tooth surface is a standard protocol for adhesive bonding, similar is the importance of conditioning the ceramic bonding surface for predictable adhesion. Hydrofluoric acid, as a surface treatment has a long term proven track record of favorable clinical outcome5. Similarly, for the formation of a durable chemical bond, silane application is recommended6,7. And many authors consider treatment of ceramic surface both with HF acid and silane as indispensable5,8-10.
In a recent study by Canay et al., 11 spectroscopic analyses showed formation of crystalline precipitates on the etched ceramic surfaces in the form of Na, K, Ca & Al by-products. These by-products of HF acid etch are readily insoluble in water and possibly contaminate the ceramic...
