The relationship between the periodontal health and the restoration of teeth is intimate and inseparable. Maintenance of gingival health constitutes one of the keys for tooth and dental restoration longevity. An adequate understanding of relationship between the periodontal tissue and restorative dentistry is essential to ensure adequate form and function of dentition and Esthetics and comfort to the patients. Restoration of fractured (traumatized), severely decayed, partially erupted (delayed passive eruption), worn or poorly restorated teeth is often difficult for the dentist without surgical and orthodontic intervention. Surgical crown lengthening of these teeth is necessary to provide adequate tooth structure for restoration or Esthetics enhancement, thus adhering to basic biological principles by preventing impingement on the periodontal attachment apparatus or biological width. Many clinicians have been unable to utilize the concept of biologic width in practical manner. Hence the purpose of this article is to describe the biologic width anatomy, evaluations & correction of its violation by different methods.Keywords

The procedure of eliminating the noise from the early picture endures to be a tough bother for researchers. The centre of attention of this paper is coupled to the pre procedure of a figure beforehand it will be utilized in applications. The pre procedure is finished by de-noising of pictures. Completely disparate noises like Gaussian sound salt and pepper sound, speckle sound span constituent used. The filtering way has been tested to be the highest after the picture is damaged alongside salt and pepper noise. The rippling chiefly established way has been tested to be the simplest in de-noising pictures contaminated alongside Gaussian noise. A digitized fingerprint picture is normally screeching. across this paper, we've utilized picture procedure methods for removing sound inside the fingerprint picture and a substitute enhancement method is projected and tested alongside success.

Aesthetic demand has increased tremendously in the recent years and so has the demand for the consequent cosmetic periodontal surgeries. One of the most common aesthetic problems encountered is the gingival recession, especially in the anterior region. Gingival recession is the exposure of ischolar_main surface due to apical migration of gingival margin. Many patients seek treatment because of aesthetic concerns, ischolar_main sensitivity or fear of loss of affected tooth. This case report describes management of gingival recession using connective tissue graft and laterally repositioned flap after ischolar_main surface biomodification.Keywords

The classification of agroclimatic zones in India was made in the 1990s for identifying priorities and developing strategies for location-specific and need-based research as well as overall agricultural development in the country. Long-term climatic parameters, particularly temperature and rainfall along with soil and crop information were used for the classification of agroclimatic zones. It has been documented with a fair degree of accuracy that overall climate is changing, particularly with respect to temperature over the Indian region. Thus it is anticipated that in the recent past, climate change may be reflected in the agroclimatic zones as well and ultimately affect the criteria of their classification based on climatic parameters. The objective of the present study is to examine the trends and spatial/temporal variability of temperature, rainfall, rainy days, and heavy rainfall in different agroclimatic zones of the country, which may help in better understanding of the further initiatives on reclassification of agroclimatic zones, if required. Using various long-term gridded data from 1985 and instrumental datasets starting from 1951 to 1980, studies have been made to observe changes in different components of the climatic variables, i.e. temperature and rainfall. It has been observed that there are significant changes in temperature and rainfall, both temporally and spatially, across India and there is a definite shift in temperature and rainfall patterns in the recent past compared to 1951–1980. It has also been inferred that there is a need to reconsider the classification of agroclimatic zones in India under the scenario of observed climate changes in the country.Keywords

Oral health is indispensable to overall health and oral diseases especially periodontitis is well known for its high prevalence and rapid morbidity. Function of the host immune response is the most crucial feature in periodontitis. And this is the reason for both disease progression and severity. Search for a biomarker for periodontitis has turned on researches working out in finding many newer molecules (cytokines), that can help the clinician in deciding regarding the patient’s status. This review shortly covers the multiple facets of crosstalk engaged by salivary Tumour Necrosis Factor-α key inflammatory mediators in periodontal disease.
