Background and Aim: Restoration of primary anterior teeth with severe caries extending to the gingival margin is challenging for many clinicians especially in uncooperative children. Resin modified glass ionomer cements (RMGICs) can be suitable for use in such cases since they require fewer application steps than composite resins. This study aimed to assess the fracture strength of severely dam...

OBJECTIVE This study compared the student's self-grades versus the examiners grades, inter examiner grades and grades of anterior with posterior teeth in a preclinical prosthodontic course. METHODS 75 students and 2 examiners participated in the study. The students prepared one anterior (upper central incisor) and one posterior (lower first molar) teeth for full veneer crowns in allocated tim...

The loss of anterior teeth leads to extreme psychological trauma, along with functional and esthetic debilitations. Healthy anterior teeth play an important role of protecting the posterior teeth during excursive mandibular movement. Loss of anterior teeth induces posterior interference with extended disocclusion time. Posterior disocclusion is critical to remove the harmful force on the teeth ...

The visibility of anterior tooth surfaces with lips at rest or during function is an important factor in determining prosthodontic outcome. There is a lack of sufficient information published on this subject. The aim of this study was to investigate the degree of visibility of maxillary and mandibular anterior teeth surfaces when the lips are at rest. Four hundred seventy three adults were exam...

OBJECTIVE The aim of this study was to investigate the three-dimensional (3D) position of the center of resistance of 4 mandibular anterior teeth, 6 mandibular anterior teeth, and the complete mandibular dentition by using 3D finite-element analysis. METHODS Finite-element models included the complete mandibular dentition, periodontal ligament, and alveolar bone. The crowns of teeth in each g...

The aesthetic requirement of severely mutilated primary anterior teeth in case of Early Childhood Caries (ECC) has been a challenge to paediatric dentists. ECC involves the upper anterior teeth early in life and by the time the dentist sees the child, most of the coronal structure is lost. This article presents the clinical sequence of rehabilitation of maxillary anterior primary teeth, and the...

The visibility of anterior teeth was studied in a population of 425 subjects. Scoring photographic data gave the percentages of anterior teeth that would not show a crown margin if it were placed in incisal, middle, or gingival sections. The results of this study indicate: their anterior teeth which would not show unless the lips were retracted.

Sphagesaurus montealtensis is a sphagesaurid whose original description was based on a comparison with Sphagesaurus huenei, the only species of the clade described to that date. Better preparation of the holotype and the discovery of a new specimen have allowed the review of some characteristics and the identification of several synapomorphies of S. montealtensis with the genus Caipirasuchus: p...
