ABSTRACT
Dens invaginatus is a developmental variation of a tooth resulting from an alteration in the normal growth pattern of the dental papilla. It is clinically characterized by a palatine furrow that can be limited to the coronal pulp or may extend to the radicular apex. The commonly affected tooth is maxillary lateral incisor. The occurrence of multiple dens invaginatus is extremely rare. Although a clinical examination may reveal a deep pit or fissure on the lingual surfaces of maxillary anterior teeth, the radiographic examination is the choice for diagnosis of dens invaginatus. Familiarity with the radiographic appearance of this anomaly is essential for the dental practitioner. The purpose of this paper is to present a clinical case of multiple dens invaginatus involving maxillary anterior teeth which was diagnosed during routine radiographic evaluation.
ABSTRACT
An algal community was used to assess the quality of water of Haranbaree dam and Mosam river of Maharashtra. Pollution tolerant genera and species of 4 groups of algae from each of 3 stations of Haranbaree dam and Mosam river were recorded. By using Palmer's index of pollution for rating of water samples the total score of each station of study area was greater than 20 indicating the confirmed high organic pollution. 34 pollution tolerant genera were recorded at all stations of dam and river. Out of 34 pollution tolerant genera, 27 genera and 33 genera were observed at the dam and river sites respectively. In present study 22 pollution tolerant species are observed at dam and river sites.
