Eruption cyst is a benign cyst associated with a primary or permanent tooth in its soft tissue phase after erupting through the bone. It is most prevalent in the Caucasian race. Intraoral examination of four patients revealed eruption cyst. Among these, in three patients it occurred in the maxillary arch and one had it in the mandibular arch. All were associated with permanent tooth. Surgical treatment was done in three cases and in one case the cyst disappeared gradually and tooth erupted in normal pattern. Four cases of eruption cyst from India are presented and literature on this condition is reviewed. It is clinically significant in that knowledge among general dentists is very essential regarding this developmental disturbance to reach the correct diagnosis and to provide proper treatment.

Pediatric dentistry in the current scenario is not just about teeth and gums that are easily visible in children's mouth anymore. It is all about those structures that are hidden, difficult to identify, and often remain undiagnosed. Dentist can come across various anomalies pertaining to the crown structure during the clinical practice. Although supernumerary tooth is the most commonly seen anomaly, the presence of extra roots in molars is an interesting example of anatomic root variation. It is well known that both primary and permanent mandibular first molars usually have roots, one mesial, and the other distal root. Very rarely an additional third root (supernumerary root) is seen and when it is located distolingually to the main distal root is called "radix entomolaris (RE)" and when it is placed mesiobuccaly to the mesial root is called "radix paramolaris (RP)." The purpose of this article is to discuss the prevalence, morphology, classification, clinical diagnosis, and significance of supernumerary roots in contemporary clinical pediatric dentistry.

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch and the talon cusp is a rare dental developmental anomaly seen on the lingual surface of anterior teeth. This paper presents a rare clinical case of development of talon cusp in a mesiodens with multiple lobes, which interfered with both occlusion and appearance of an 11-year-old patient. During clinical interview, the patient reported difficulty on mastication. Clinical and radiographic examination revealed that a supernumerary tooth with completely formed root was causing an occlusal interference. The supernumerary tooth was diagnosed as multi-lobed mesiodens associated with a palatal talon cusp. The treatment plan consisted in the extraction of the supernumerary tooth followed by orthodontic treatment for diastema closure and tooth alignment.

Traumatic injuries to maxillary anterior teeth are a common finding in children because of falls while playing. Sequelae of trauma to dental hard tissue include broken, lost, aspirated and swallowed teeth. One additional hazard is the embedding of fractured tooth fragments in the soft tissues, particularly in the lip. A 10-year-old male patient complained of pain in the lower lip. There was a history of trauma to the upper anterior tooth 10 months previously. Clinical examination showed scarring and discoloration over the lower lip, and the presence of a hard mass was felt on palpation. Intraoral examination revealed an Ellis and Davey class II fracture of number 11. A radiograph of the lip was taken, which showed a radiopaque structure similar to the shape of the missing tooth fragment. Under local anesthesia, the tooth fragment was removed successfully, and the class II fracture was restored with composite. Therefore, proper clinical and complete radiographic examination of both hard and soft tissues following dental trauma is essential to rule out such occurrences.
