Investigating the effect of bruxism on maxillary arch length and width in children using three-dimensional digital model analysis.

Background: Bruxism is defined as repetitive jaw-muscle activity characterized by the grinding and clenching of teeth. The prevalence of bruxism in children is extensive, and it can cause irregularities in dental arches. The study aimed to investigate the presence of any effects of bruxism on maxillary arch length and width in children using three-dimensional (3D) digital model analysis.

Relationship between Severe Early Childhood Caries and dental development.

Aim: Severe early childhood caries (sECC) is a public health problem that continues to affect infants and preschool children worldwide. Knowledge of the changes in dental development is important for paediatric dentists in order to determine a treatment plan. The aim of this study was to investigate dental development in children with sECC, compared to age and gender-matched controls, by calculating the dental age (DA).

Evaluation of root canal morphology of human primary mandibular second molars by using cone beam computed tomography.

Objectives: The aim of the present study was to investigate the root canal configurations of primary mandibular second molars (PMSMs) using Vertucci classification. Materials and Methods: The root canal types of 228 PMSMs (228 mesial and 228 distal roots) were evaluated. In addition, the relationship between external root morphology and Vertucci classification was investigated.

Severe unintentional extrusion of mineral trioxide aggregate during apexification.

The aim of this report was to present the long-term clinical and radiographic outcomes of a case including severe unintentional extrusion of mineral trioxide aggregate (MTA). An 11-year-old boy was referred with a previously traumatized permanent central incisor which was temporarily treated by using calcium hydroxide root canal filling material. Since having an open apex and a large periapical lesion, root canal treatment with MTA apexification was planned.

Retrospective evaluation of healing of periapical lesions after unintentional extrusion of mineral trioxide aggregate.

Background: During the apexification procedure for teeth with open apices, mineral trioxide aggregate (MTA) may be unintentionally extruded. The aim of the present study was the retrospective evaluation of the healing of periapical lesions in permanent incisor teeth with open apices after the unintentional extrusion of MTA.

Methods: The clinical and radiographic records of 55 maxillary permanent central teeth treated by MTA apexification were evaluated.
