Compared to all other dental disciplines, implant dentistry has rapidly evolved, with progressive innovations, mainly in terms of development of new implant systems and the introduction of new surgical techniques.    Formation of a direct bone to implant contact is the main success criteria in implant dentistry. Porous surface coating should enhance integration, by allowing bone growth inside the pores however, the number and size of the pores that can be obtained on the surface of the implant determine the quality and quantity of the bone growth. Histological studies showed that while a pore size of ̴ 100 μm is adequate for bone ingrowth, osteon formation inside a porous material needs ̴ 150 μm pores, while pores greater than ̴ 300 μm are required to support vascularized bone in growth.

Bruxism consists in a movement characterized by tooth grinding, attrition or clenching. According to the International Classification of Sleep Disorders, the bruxism is a movement disturb related to sleep, characterized repeated contractions of the masticatory muscles, resulting in grinding or clenching of the teeth.  Although some similarities can be found between wake-time and sleep bruxism, differences related to state of consciousness and oral motor excitability are present. In the wake-time bruxism, the individual is often not aware of the habit, and is frequently related to vicious habit; on the other hand, sleep bruxism is an unconscious activity of clenching or grinding the teeth, producing sounds while the individual is sleeping. In sleep bruxism, there are exacerbated occlusal forces duringthe parafunctional activity in periods of no conscience. These occlusal forces were not inhibited by cortical and subcortical proprioceptive mechanisms and, thus, a lot of sign

Even in decline, dental decay is still one of the most frequently diseases in humans, starting soon after the eruption and whose prevalence is increasing with age.  In the last decades, the biochemical and morphological researches of the processes that are taking place at the enamel surface and at the enamel-oral fluids interface, demonstrated that dental decay was not the result of a continuous demineralization of the enamel by the action of the acids resulting from the fermentative processes in the bacterial dental plaque, but the result of an alternation of successive de- and remineralizations. The evolution of the carious process is the result of loosing the equilibrium between the deand re-mineralization processes, all of these being dependent by the composition and the chemical status of the oral fluids - the saliva and plaque fluid.  PDF LINK>>>>>>>

The developmental dental anomaly Talon's cusp was first described by Mitchell in 1892 as a horn like process, curving from the base downward to the cutting edge on the lingual surface of a maxillary central incisor of a female patient. This accessory cusp was named by Mellor and Ripa as Talon's cusp because of its resemblance in shape of eagle’s talon. It occurs more frequently in maxilla than mandible and maxillary anterior region has more prevalence as compared to posterior.  The permanent dentition is affected more as compared to the primary dentition, and the males being affected more than females. Talon’s cusp of anterior teeth is characterized by the presence of an accessory cusp like structure projecting from cingulum area of cementoenamel junction. Fusion is characterized by union of two or more hard tissues of two or more teeth by their dentin and pulp. The co-occurrence of two developmental dental anomalies is rare. Talon’s cusp in fused permanent mandib

Saliva plays a vital role in maintaining the health and integrity of the oral tissues. Among the various components of saliva, the proteins protect the oral cavity against pathogens and diseases like dental caries and mucositis. Similar to salivary proteins, plasma proteins are essential in maintaining the various functions of the body.  The kidneys play a major role in the retention of these proteins. Proteinuria is a condition where plasma proteins are lost from the body via urine. Proteinuria is common in children and occurs as a result of a variety of factors. Urinary loss of plasma proteins results in hypoproteinemia . This study aims at understanding the implications of hypoproteinemic state due to proteinuria on the levels of salivary proteins.

The periodontal disease is a major public health problem, which affects up to 90% of the worldwide population. Gingivitis always precedes periodontal disease. The main characteristic of periodontal disease is destruction of supporting tissue of the tooth. The main etiological factor is microbial oral biofilm. Periodontal pathogens are: Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Treponema denticola etc. Aggregatibacteractinomycetemcomitans is commonly associated with this disease, especially in young adults. Some new studies demonstrate that Herpes viruses can be involved in pathogenesis of periodontal disease.  Periodontal inflammation is followed by release of bacterial leucotoxins, collagenases, fibrinolysins, and other proteases. Increased leukocyte infiltration and changes in vascular permeability have always been present in periodontal tissues inflammation. Antibiotics (tetracyclines and metronidazole), antiseptics (chlorhe
