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.

    • "Dash et al. [2] presented a case of talon cusp affecting the mandibular central incisor and maxillary lateral incisor, an inverted impacted migrating mandibular second premolar, and hypodontia . Recently Suprabha et al. [3] showed presence of multiple dens invaginatus, generalized enamel hypoplasia, generalized microdontia, root resorption and multiple periapical lesions, and supernumerary teeth. Preeruptive, intraosseous migration of a tooth across the midline is termed " transmigration " [4] [5] [6]. "

    ABSTRACT: Dental anomalies are the formative defects caused by genetic disturbances or environmental factors during tooth morphogenesis. Simultaneous occurrence of various multiple anomalies has been reported previously, particularly in cases of chromosomal abnormalities that often manifest with multisystem involvement. Very few cases of multiple anomalies have been documented in patients with no known generalized abnormalities. The present paper shows an unusual occurrence of a combination of dental anomalies like mandibular canine transmigration, taurodontism in permanent mandibular molars, congenital agenesis of 14 numbers of permanent teeth excluding third molars, canine impaction, primary molars with pyramidal roots, midline diastema and generalized microdontia in an apparently normal 13-year-old Indian girl.

    • "This allows the permanent tooth to move through the labiolingual bone plate, which is maintained by the residual crown-root portion of the second deciduous molar, thus avoiding unwanted mesial rotation. The drawback of hemisection technique is that the patient must visit the dentist twice for the hemisection and the extraction of the deciduous tooth.[21] "

    ABSTRACT: The second premolars have the highest incidence of congenital absence, after the third molars. The problem resides not in the prevalence of congenitally missing premolars but in the selection of a treatment plan that will yield the best results over the long term. The present study reports a case of a 14 year old female patient with bilaterally congenitally missing second mandibular premolars with associated crowding of teeth. The case has been managed using a multi-speciality approach, in which both deciduous mandibular second molars were sectioned and the distal half retained. The retained half was prepared to receive a full coverage restoration which was contoured as a premolar. The space created was then utilized to correct the crowding by fixed orthodontics. A two year follow up shows retained distal half of the deciduous mandibular second molar with correction of crowding and space closure.

    ABSTRACT: Experimental testing of a prototype knowledge-based message generation system (KMGS) is discussed. The test was conducted to better understand the potential of the use of artificial intelligence (AI) techniques in the development of a nonvocal communication device. The communication rate of the system with respect to user's motor ability, system's scanning tolerance, and the use of both fixed statistical information and dynamic speech information are examined. Test results and discussions are presented
