Introduction: Bolton ratio is considered as seventh key of normal occlusion. Many orthodontic patients have to undergo premolar extractions as a part of treatment. Aims and objectives: The present study was taken up to investigate the effect of premolar extractions on Bolton’s overall ratios in a sample of north Indian population. Materials and methods: Mesiodistal tooth widths were measured on...

PURPOSE This prospective study followed 61 patients who were partially dentulous and considered to have insufficient bone volume for routine implant treatment and consequently underwent sinus inlay bone grafting. PATIENTS AND METHODS The patients were treated with maxillary sinus floor augmentation with particulated autogenous bone from the mandibular ramus/corpus. After a healing period, den...

objective: To evaluate the validity of Pont’s index in Nepalese population and establish the regression equation to predict probable arch width from sum of the maxillary incisors. Materials & Method: The sample comprised of 50 female and 50 male subjects of the age ranging 17-24 years. Sum of the mesio-distal widths of the maxillary incisors were measured. Descriptive statistics, Coefficient of...

OBJECTIVE To produce buccal translation and determine whether buccal bone forms on the cortical surfaces. MATERIALS AND METHODS Eleven patients requiring maxillary first premolar extractions participated in this prospective, randomized, split-mouth study. Pre- and posttreatment records included models, photographs, and small field of view CBCT images. One randomly chosen maxillary first premo...

IJMDS ● www.ijmds.org ● January 2015; 4(1) 560 Original Article Influence of first premolar extraction on second and third molar angulation A clinical study Tarvade SMT, Biday S ABSTRACT Background: In modern populations, the impaction rate is higher for third molars than for any other tooth. Due to the speculation of third molar role on late incisor crowding, many orthodontists prescribe remov...

INTRODUCTION We investigated the root canal configuration of maxillary premolars in a Spanish population by using cone-beam computed tomography. METHODS Images of 804 maxillary first and second premolars were obtained from 620 patients who underwent cone-beam computed tomography scanning during preoperative assessment (before implant surgery, orthodontic treatment, dentoalveolar trauma diagno...

Dentigerous cyst is the most frequently encountered odontogenic cyst which is epithelial lined and is developmental in origin. It usually affects young males below 30 years of age. Thus, its early diagnosis and treatment with rehabilitation becomes very important. Here a series of three cases with rare involvement of impacted maxillary lateral incisor, maxillary premolar and mandibular canine i...
