The interpretation of an image for the dento-maxillofacial region is complicated due to the complex anatomy and the varying radio density of the tissues. The classic 2 dimensional radiographic technique do provide an excellent representation of the tissues, but are limited in differentiating superimposing structures. This drawback has been be overcome by Cone Beam Computed Tomography (CBCT). CBCT is a medical imaging technique consisting of X-ray based computed tomography where the X-rays are divergent forming a cone. It has the ability to eliminate superimposition of structures that normally overlap in the commonly used two-dimensional radiography. CBCT produces a high contrast image with good resolution in a short period of time. In endodontics, this particularly relates to early diagnosis of periradicular disease with greater precision of lesion size, extent and nature of position. CBCT also provides a lower dose of radiation and a higher image quality when compared to medical tomography. It can provide clear distinction of the delicate structures such as the dentin, enamel, pulp cavity and the alveolar cortical. CBCT system configurations are also available that provide small field of view images at low dose with sufficient spatial resolution. These characteristics make it highly relevant for applications in endodontic diagnosis, treatment guidance and post treatment evaluation. This article provides a literature overview of CBCT as an imaging adjunct in the field of dental science, more specifically in endodontics.

The mandibular canine shows an unusual tendency to migrate to the opposite side of the jaw. Numerous theories have been proposed to explain this rare phenomenon and a broad classification has also been proposed. This paper reports a series of 2 cases with mandibular canine transmigration with specialemphasis on etiology and classification of transmigrations

An7-year school going boy came with a chief complaint of an abnormally shaped tooth situated in upper front teeth region. On examination a supernumerary tooth with multiple lobes was present in between to the maxillary permanent central incisor. The morphology of the tooth crown was found to be unusual due to the presence of three lobes in the crown portion. Because of the supernumerary tooth, the permanent right central incisor was displaced distally creating a midline diastema. Radiographic examination showed a completely formed supernumerary tooth with single root. On the basis of clinical and radiographic examination, the supernumerary tooth was diagnosed as multilobed mesiodens. Since patient expressed dissatisfaction with the presence of supernumerary tooth, it was decided to extract this mesiodens followed by orthodontic treatment for midline diastema in maxillary central incisors.

Congenitally missing teethare frequently presented to the dentist. Interdisciplinary approach may be needed for the proper treatment plan. The available treatment modalities to replace congenitally missing teeth include prosthodontic fixed and removable prostheses, resin bonded retainers, orthodontic movement of maxillary canine to the lateral incisor site and single tooth implants. Dental implants offer a promising treatment option for placement of congenitally missing teeth. Interdisciplinary approach may be needed in these cases. This article aims to present a case report of replacement of bilaterally congenitally missing maxillary lateral incisors with dental implants

To study the maternal view regarding pain relief, neonatal outcome, labour outcome under epidural anesthesia and to study the duration of various stages of labour and progress of labourunder epidural anesthesia The present study comprises of continuous lumbar epidural analgesia with Bupivacaine (0.125%) pain relief during labour, carried out at Obstetrics and gynecology Department in collaboration with Anesthesiology Department of a Teaching General Hospital. A total of 100 cases (primigravidas) were studied out of 50 received continuous lumbar epidural analgesia and 50 served as control.There is an association between epidural analgesia and labour outcome, but this is probably not causative. In present study incidence of LSCS is 8%. In present study also there is no significant difference between caesarean delivery rates in group A (epidural group) and group B (control group). In our study there was no statistical difference in the duration of the active-first and the second stages of labor in both groups. In our study, the cesarean delivery as well as vacuum-assisted and instrumental delivery rates was not significantly different between both the groups.Epidural analgesia is highly effective and safe for both mother and foetus during labour..It is proved to be effective in reducing pain, has no significant impact on the risk of cesarean section, maternal satisfaction is high, and does not have effecton the neonate

The present study was done to evaluate the effectiveness of distraction osteogenesis as a treatment modality in case of craniofacial deformity associated with cleft lip and palate patients and to suggest a protocol for distraction osteogenesisfor midface and dentoalveolar segments in cleft lip and palate patients. Seven patients with cleft lip and palate having midfacial deficiency and falling in ASA grade 1 and ASA grade 2 categories were selected and taken up for the necessary treatment withthe use of a Le Fort 1 osteotomy and application of Rigid external distractor (RED). The distraction was carried out over a period of 6-13 days at a rate of 4.0 mm per day for four patients, 1.5 mm per day for one patient (split over twice daily) and 2.0 mm per day for two patients. Advancement of the segment achieved at the end of one month fell in the range of 14 mm –18 mm and 4 mm -16 mm at the end of six months. Distraction osteogenesis proved to be an effective treatment modality in case of craniofacial deformity associated with cleft lip and palate patients. We have also suggested a protocol for distraction osteogenesis for midface and dentoalveolar segments in such patients
