ABSTRACT
Dental anomalies have been known to occur in humans due to a variety of genetic and environmental factors. Combinations of dental anomalies are known to be associated with specific syndromes. A few cases of multiple dental anomalies have been reported in patients with no generalized abnormalities. This case report describes an unusual occurrence of a combination of dental anomalies in an apparently normal healthy 12-year-old female patient. The dental anomalies in this patient were multiple dens invaginatus, generalized enamel hypoplasia, generalized microdontia, root resorption and multiple periapical lesions, shovel shaped incisors, cup shaped premolars, taurodontism, hypodontia and supernumerary teeth.

The occurrence of combined injury of intrusion, avulsion and lateral luxation is rare and the mechanism responsible for this is intriguing. This case report describes such a combined injury and its management. The rationale behind the treatment modalities is discussed.

Ankylosis of primary mandibular molars has been routinely found to be associated with various developmental disturbances in permanent dentition such as aplasia of the succedaneous tooth, ectopic eruption of the premolar, infraoclusion of the ankylosed tooth leading to tipping of the first permanent molar etc. This article describes a rare case where there was ankylosis of a mandibular second primary molar along with congenitally missing first permanent molar which resulted in the transposition of second premolar. Treatment options and prognosis of the case are discussed.
ABSTRACT
Delayed development and eruption of all the permanent molars is a rare phenomenon, which can cause disturbance in the developing occlusion. The eruption of permanent first and second molars is very important for the coordination of facial growth and for providing sufficient occlusal support for undisturbed mastication. In the case described, the first permanent molars were delayed in their development and were seen erupting at the age of nine and a half years. Severe disparity between the left and the right side of the dentition with respect to the rate of development of molars were also present.
ABSTRACT
Dens in dente are known to be associated with many dental abnormalities such as taurodontism microdontia, gemination, and dens evaginatus. This paper describes a rare case of double dens in dente in a lateral incisor with crown morphology similar to a premolar present in a patient with features of albinism. Problems associated with this condition and their management is discussed.
ABSTRACT
Sturge-Weber syndrome is an uncommon condition characterized by presence of Portwine stains on the face along with ocular disorders, mental retardation, oral involvement and leptomeningeal angiomas. A report of a case with atypical manifestations of this syndrome along with a step-by-step protocol oral rehabilitation of such patients is described.
ABSTRACT
Hereditary ectodermal dysplasia is an inherited disorder involving skin, hair, nails and teeth. Two main clinical forms have been described--hypohidrotic type and hidrotic type. A case of ectodermal dysplasia with absence of hypohidrosis and defective nails has been reported. The importance of early prosthetic management has been discussed.

The importance of apical seal has always been stressed in endodontic therapy. Root canal sealers have been used along with gutta percha to enhance the seal. The apical sealing ability of AH26/silverfree, a modified version of AH26, a resin based sealer was compared with tubliseal, a zincoxide eugenol based sealer using methylene blue dye penetration method. AH26/silverfree showed superior sealing ability.

In the past few years the importance of coronal seal following root canal therapy has been emphasised. Adhesive restorative materials have been used, considering their good bond strength and their sealing ability. In this study, the sealing ability of resin modified glass ionomer has been compared with composite resin used with fifth generation bonding agent (in vitro), using methylene blue dye penetration method. Resin modified glass ionomer showed greater leakage than composite resin, although it was not statistically significant. Further studies are needed to asses the sealing efficacy in clinical situations.
