Nonsurgical treatment of periapical lesion associated with type III dens invaginatus using calcium hydroxide: a case report.

Dens invaginatus is a developmental malformation of teeth, probably resulting from an infolding of the papilla during tooth development. It predisposes the tooth to develop caries and periapical pathosis. Root canal therapy may present many problems because of the complex anatomy of the teeth. The purpose of this case report is to describe the endodontic treatment of an Oehlers type III dens invaginatus that perforated into the apical area. Calcium hydroxide powder mixed with normal saline, was used as an intracanal medicament. This eradicated the pathogenic microorganisms in the invagination and preserved the vitality of the tooth, allowing gutta-percha obturation in the invagination.

Dentigerous cysts of anterior maxilla in a young child: a case report.

Dentigerous cysts are the most common bony lesions of the jaws in children. It is one of the most prevalent types of odontogenic cysts associated with an erupted or developing tooth, particularly the mandibular third molars; the other teeth that are commonly affected are, in order of frequency, the maxillary canines, the maxillary third molars and, rarely, the central incisor. Radiographically, the cyst appears as ovoid well-demarcated unilocular radiolucency with a sclerotic border. The present case report describes the surgical enucleation of a dentigerous cyst involving the permanent maxillary right central incisor; the surgery was followed by oral rehabilitation. Careful evaluation of the history and the clinical and radiographical findings help clinicians to correctly diagnose the condition, identify the etiological factors, and administer the appropriate treatment.

An unusual presentation of all the mandibular anterior teeth with two root canals - A case report.

A rare case of two root canals in all mandibular anterior teeth is presented. The patient initially reported for the treatment of mandibular right central and lateral incisors. However, radiographic evaluation revealed variant root canal and apical foramen patterns.

Periapical repair and apical closure of a pulpless tooth using calcium hydroxide--a case report.

A case with a open apex and a large periapical lesion in a 10 year old boy is presented. The lesion formed as a result of necrosis from trauma to a maxillary right central incisor 1 year ago. Apical closure and complete healing of periapical lesion was observed after non-surgical endodontic treatment using calcium hydroxide paste. This report suggests that even large periapical lesions could respond favourably to non-surgical treatment.

Comparative evaluation of lyophilized freeze dried platelet derived preparation with calcium hydroxide as pulpotomy agents in primary molars.

The aim of this study was to compare the efficacy of lyophilized freeze dried platelet derived preparation with calcium hydroxide as pulpotomy agents in primary molars. Fifty six primary molars in 28 children were treated by a conventional pulpotomy technique. 28 teeth were treated by lyophilized freeze-dried platelet derived preparation and another 28 by calcium hydroxide. Clinical evaluation was carried out out at 1, 3, and 6-months interval and the radiographic evaluation was carried out at 1 and 6-months. The success rate of lyophilized freeze-dried platelet derived preparation proved better than calcium hydroxide.

Hypertaurodontism in molars and premolars: management of two rare cases.

The management of two cases of hypertaurodontism, is presented. The first case shows this uncommon dental anomaly in all the four permanent first molars. The second case is concerned with endodontic management of a hypertaurodontic mandibular second premolar. The authors wish to highlight the importance of careful radiographic examination in diagnosing this rare dental anomaly in view of the difficulties encountered in performing endodontic treatment.
