ABSTRACT
An incompletely formed apex [open apex] is one of the most common features seen in immature permanent teeth after dental trauma. Endodontic treatment of open apex teeth presents with problems of overfilling and poor apical seal, thus it is imperative to create an artificial apical barrier or to induce apical closure with calcified tissue. Different materials have been tried for Apexification procedure, the most common are calcium hydroxide and mineral trioxide aggregate [MTA]. The objective of this article was to compare the effectiveness of Mineral Trioxide Aggregate and Calcium hydroxide in creating apical closure.This is a comparative study of 80 patients with Open Apex teeth. They were randomly allotted into two groups [Group A and Group B]. In Group A[ 40 patients], calcium hydroxide was used as an apexification material, While in Group B [ 40 patients] apical plugs were produced with mineral trioxide aggregates [MTA] followed by obturation. In Group A,30 patients showed complete absence of lesion while in Group B, 37 patients showed complete healing. Ten patients showed no healing in Group A, because of improper packing of mate-rial into the canal, while only three patients showed no healing in Group B because of poor delivery of MTA to the apex. The results showed that 75% teeth had complete healing in Group A and 92.5 % had complete healing in Group B. The results of the study concluded that MTA is significantly better than Ca [OH]2 in Apexification of non- vital immature permanent teeth
ABSTRACT
Palato gingival grooves, also called palatoradicular grooves or radicular lingual grooves are developmental anomalies in which an infolding of the inner enamel epithelium and Hertwig's epithelial root sheath create a groove that passes from the cingulam and extend varying distances apically on to the root. The purpose of this study was to determine the prevalence of palato gingival groove in maxillary lateral incisors, and prevalence of caries in the groove. 200 patients of age ranged between 15-40 years, attending the Punjab Dental Hospital, Lahore were randomly selected for examination. Patients with missing or crowned lateral incisors were excluded from the study. All lateral incisors were carefully examined for the presence, extension of palato gingival and caries development in groove. The prevalence of palato gingival groove was 10%. They were found to be 6.75% as coronal groove and 3.25% as an apical groove. Bilateralism was found to be 57.5%, 63% for coronal and 46.15% for apical grooves. In male patients the prevalence was 65% and in female patients 35%. Caries prevalence was 35%, 18.5% for coronal groove and 69% for apical groove. It was concluded that prevalence of palato gingival groove is high in this community and show increased caries incidence

This article presents a case report of endodontic treatment and apicectomy as well as enucleation of large radicular cyst associated with maxillary right central, lateral and canine teeth accompanying labial expansion. Cystic lesion was removed surgically under local anesthesia and apicectomies were done after the completion of root canal treatment

Dens invaginatus is a developmental malformation of teeth.Affected teeth show a deep infolding of enamel and dentine starting from the foramen caecum or even the tip of the cusps and which may extend deep into the root. Teeth most affected are maxillary lateral incisors. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. Root canal therapy may present severe problems because of complex anatomy of teeth. Aetiology, classification, prevalence, diagnosis and treatment considerations are reviewed
