Evaluation of the pit and fissure system in primary and permanent molars with micro-computed tomography and 3D printing.

This study aimed to characterize the anatomical and physiological features of pits and fissures in primary and permanent molars by microtomographic (micro-CT) examination and three-dimensional (3D) printing. The occlusal surfaces of 84 primary molars and 60 permanent third molars were examined. The samples were scanned with micro-CT and the occlusal surface separated.

Dynamics of Gingival Indices and Microbiological Findings During Treatment of Plaque-Induced Gingivitis in Children Aged 10-14 Years.

Background: The study analyzed the dynamics of the clinical periodontal status during the treatment of adolescents with generalized plaque-induced gingivitis.

Aim: Assessment of the predominant subgingival microflora in the case of a diagnosed inflammatory process in the gingiva in childhood.

Methods: Full-mouth periodontal assessment of plaque accumulation and bleeding on probing with an electronic periodontal probe was performed during the treatment of 34 adolescents with generalized plaque-induced gingivitis.

Application of Contemporary Magnifying Methods in the Diagnostics of Occlusal Carious Lesions on First Permanent Molars in Children.

Introduction: Dental operating microscopes (DOM) enable dentists to examine, with the aid of magnification and photodocumentation in clinical conditions, the occlusal anatomy of newly erupted permanent molars and to detect any early carious lesions more precisely.

Aim: To determine the advantages of magnifying technology in detecting early occlusal carious lesions in newly erupted permanent first molars.

Materials And Methods: We examined 176 first molars of 44 children divided into two age groups: 7-8 and 9-10 years.

Depth of Gingival Sulcus in Healthy Children with Erupting Permanent Teeth.

Introduction: Measuring the gingival sulcus depth in children while their permanent teeth erupt is rather difficult especially if using reference norms for adults for a base.

Aim: Assessment of the depth of the gingival sulcus during the period of tooth eruption in healthy children.

Materials And Methods: Thirty children were included in the study (age range 6 - 14 yrs).

Subgingival Microbiota during Formation of Permanent Dentition.

Background: Periodontal pathology in children has distinctive characteristics that can be accounted for by the peculiarities of the age, the dynamically changing oral environment, and the processes of formation and stabilization of periodontal structures during teeth eruption.

Aim: The aim of this study was to investigate the composition of the subgingival microbiota during permanent dentition formation in puberty.

Materials And Methods: The study included 30 children aged between 10 and 15 years without gingivitis (up to 25% PBI), with good oral hygiene, with no systemic diseases or reception of antibiotics for 3 months.
