A Cephalometric study, using Tetragon Analysis, was performed on Lateral Cephalograms of 60 Orthodontically untreated individuals from local population ranging from the age groups of 18 to 30 years. The purpose of this study was to evaluate the dentoskeletal characteristics of these subjects, to establish cephalometric norms using Tetragon analysis, and to evaluate the cephalometric values for Class II and Class III malocclusion groups using Tetragon analysis. The sample was divided into four groups (1 to 4) comprising of Normal occlusion, Class II Division 1 Malocclusion, Class II Division 2 Malocclusion, and Class III Malocclusion Respectively. Descriptive data that included mean, standard deviation and range values were calculated for each group. 95% confidence intervals (limits) were provided for Group I. Between Groups were compared by using Student's t-test. The results of this study indicate that the norms established from this study should be used to evaluate the dentoskeletal relationship of our local population, for Tetragon Analysis, because certain differences have been noted between the original and current study. Thus by using the local norms one will get more accurate picture of the dentoskeletal relationship for the local population.

Treating healthy but unaesthetic teeth has been a major challenge for a dental practitioner. Maxillary midline diastemas are one such aberration in the smile zone. Although a diastema can be transient in the developing dentition, the management of the diastema in adulthood requires a detailed examination and appropriate care for a successful outcome. Majority of specialty dentists prefer conservative or minimally invasive treatments, such as porcelain laminate veneer (PLV) restorations over full-ceramic crowns for anterior teeth, where esthetics can be extremely concerning. Minimal-thickness laminate veneers provide a satisfactory outcome while preserving the dental structure as a whole. Thus, this clinical report describes a conservative approach of minimal preparation utilizing a restoration to accomplish both esthetic and functional rehabilitation.

Crown fractu res account for a majority of the traumatic injuries in the oral cavity. This usually requires a multidisciplinary approach for esthetic and fu nctional rehabilitation . Thi s case report describes the management of a sub gingiva ll y fractured permanent central incisor by endodontica lly treating the tooth,orthodontically extruding the tooth using a removable appliance and thereon restoring it to normal esthetics and fu nction with a porcelain fused to metal crown.
