trauma to primary teeth can lead to devastating sequels in development of permanent successors. the disturbance may range from enamel hypoplasia and/or hypo-calcification to arrest of dental bud development. crown dilaceration of permanent teeth is one of the consequences of trauma to deciduous teeth mainly due to intrusion or avulsion. this report presents a mandibular central incisor with dil...

Individuals affected by ectodermal dysplasia syndromes have abnormalities of the glands, tooth buds, hair follicles, and nail development. Oral finding in ectodermal dysplasia patient are significant and can include multiple abnormalities of the dentition such as anodontia, hy-podontia or malformed and widely spaced peg like teeth, loss of occlusal vertical dimension, protuberant lips and lack ...

In cases of an immediate insertion and loading of implants after a traumatic loss of the patient's own dentition or due to an inevitable extraction of an anterior tooth, it is essential to provide the patient with an adequate provisional crown. A soft-tissue recession must be avoided, whether it is due to a compression of the peri-implant soft-tissue caused by an over-dimensioned restoration in...

INTRODUCTION Chronic regurgitation of gastric acids in patients with gastroesophageal reflux disease may cause dental erosion, which can lead in combination with attrition or bruxism to extensive loss of coronal tooth tissue. CASE PRESENTATION This clinical report describes treatment of severe tooth wear of a gastroesophageal reflux disease patient who is 54-year-old Turkish male patient. Aft...

PURPOSE Pathologic tooth migration (PTM) is a tooth displacement which is derived from imbalance of tooth retention force and is dominantly found out in maxillary anterior area. PTM in maxillary anterior area was tried to corrected with periodontal treatment and a clear aligner in this study and the result was evaluated clinically and radiographically. METHODS For the treatment of a patient w...

let r be a commutative noetherian ring. we study the behavior of injectiveand at dimension of r-modules under the functors homr(-,-) and -×r-.

OBJECTIVES To obtain maxillary anterior tooth dimension and proportion values for the Central Chinese population and to evaluate the existence of sexual dimorphism, any consistent relationships between the tooth ratios, and the presence of golden proportions. METHODS Tooth dimensions and proportions of six maxillary anterior teeth were recorded on gypsum casts obtained from 147 subjects (82 w...

INTRODUCTION Tooth-size studies are important in orthodontics. Our aim in this study was to establish normative data on tooth size with a clustering method. METHODS Dental casts of 307 subjects with normal occlusion were examined. In these subjects, the tooth-size data sets in the maxilla and the mandible were clustered for men and women by using multivariate normal mixture models. This analy...

Providing complete denture therapy to patients with atrophic residual alveolar ridges is challenging. Because these patients suffer ongoing diminution of the denture foundation, modern approaches often involve dental implant therapy as a means of improving the denture foundation and supplementing the mechanics of prosthesis support, retention, and stability. Regardless of implant availability, ...

INTRODUCTION: The intrapsychic process of resorting to the symbolic is innate and prepares child for organization his internal world. Throughout child's developmental trajectory, its playful projective expression, allows us assess psychographically internalized stages development. present study aims evaluate mental representation concept symbolism, size, perspective designed percepts al...
