Dental Caries in the First Permanent Molar during the Mixed Dentition Stage.

The early eruption of the first permanent molar (FPM) favors its exposure to the risk factors for dental caries specific to the mixed dentition stage of dental development. The aim of this study was to assess the prevalence and distribution pattern of FPM dental caries and of the consequences of this pathology - caries with pulp involvement in the FPM and missing FPM (FPM extraction) in a sample of Romanian children during the mixed dentition stage. To evaluate the effect of asanas in Yoga on the IOP of practicing individuals.

A clinical and statistical study on enamel hypomineralization of the first permanent molar in the period of mixed dentition.

Background: The first permanent molar (FPM) is the first tooth in the permanent dentition that emerges in the oral cavity, at around the age of six and behind the deciduous teeth, thus converting the primary dentition into a mixed dentition. Its early formation represents a risk factor for the onset of hard dental tissues disorders, the most common being the molar incisor hypomineralization (MIH).

Aim: The aim of the study was to assess the hypomineralization type of developmental defects of enamel at FPM level during the mixed dentition stage, in a group of Romanian children.

Morphological assessment of the mandibular canal trajectory in edentate subjects.

Background: The mandibular canal and its content represent the vital structure, which can complicate dentoalveolar surgical procedures in the posterior region of the mandible. The purpose of the present study was to determine the path the mandibular canal takes in relation to the horizontal and the vertical anatomical reference planes in edentate subjects, in order to minimize the risk of affecting its neurovascular content during various oral surgery procedures.

Materials And Methods: Morphometric evaluations were performed on 12 dried fully edentulous human mandibles and on cone-beam computed tomography (CBCT) cross-sectional images of the mandible, from 20 patients with either partial or complete edentulism.

Out-of-water constitutional self-organization of chitosan-cinnamaldehyde dynagels.

An investigation of the constitutional adaptive gelation process of chitosan/cinnamaldehyde (C/Cy) dynagels is reported. These gels generate timely variant macroscopic organization across extended scales. In the first stage, imine-bond formation takes place "in-water" and generates low-ordered hydrogels.

Alveolar bone dehiscences and fenestrations: an anatomical study and review.

Aim: To determine the prevalence and distribution of fenestrations and dehiscences of the jaw bones among the Caucasian population, to find if any correlations can be established between their occurrence and certain teeth characteristics and to discuss the clinical implications the defects of alveolar process could have.

Material And Methods: 138 skulls of specimens ranging from 21 to 54 years of age, having either complete dentition or reduced number of missing teeth were studied. Teeth found to have one of the two defects were examined for signs of faceting (attrition) that was considered an indicative for excessive occlusal forces and were submitted (except for the case of the third molars) to an analysis concerning their bucco-lingual inclination in the jaw.
