    Objectives Gingival phenotype is closely related to treatment success and aesthetic results in the maxillary anterior region. Several methods were proposed to measure the dimensions of the gingival tissue. This study aimed to evaluate the gingival thickness using clinical and radiographic techniques and to explore the association between gingival thickness and gingival phenotypes classified by color-coded phenotype probes. Materials and methods The gingival thickness of 86 periodontally healthy maxillary anterior teeth was assessed using transgingival probing (TGP) and cone-beam computed tomography (CBCT). The gingival phenotype was classified as thin, medium, thick, or very thick by transparency of the color-coded probes through the gingival sulcus. The labial alveolar bone thickness was measured on CBCT images. The keratinized tissue width (KTW) was recorded. Results Good to excellent agreement was found between TGP and CBCT regarding the thickness of the gingiva (p<0.001). There was a very high correlation between the phenotypes determined by color-coded probes and the gingival thickness measured by TGP (r=0.953, p<0.001). KTW was significantly higher in thick and very thick phenotype groups compared with thin phenotype group. Conclusion Cone-beam computed tomography images and the probe transparency method with color-coded probes are reliable for identifying the gingival phenotype in the maxillary anterior region, based on comparisons to direct transgingival probing.

    Retrospective Evaluation of Cone-Beam Computed Tomography Findings of Odontogenic Cysts in Children and Adolescents
    (2021) Yilmaz, B. B.; Yalcin, E.D.; 0000-0003-0633-5648; 33473032
    Background: Odontogenic cysts develop from the epithelium of dental structures and generally grow slowly. In children and adolescents, cysts usually grow faster than adults and require much knowledge for diagnoses and treatments. Aims: This study aimed to determine the diagnosis and treatment of odontogenic cysts in different age groups by evaluating the type of lesions, age, gender, and anatomical distribution of odontogenic cysts seen in children and adolescents by cone-beam computed tomography. Materials and Methods: A total of 42 odontogenic cysts (radicular, dentigerous cyst, and odontogenic keratocyst) were determined in children and adolescents aged 7-18 years. Cone-beam computed tomography images of odontogenic cysts were analyzed in terms of types, age, sex, anatomical location, height, width, depth, scalloped borders, lesion shapes, tooth displacement, root resorption, and association with an unerupted tooth. Results: There was a significant correlation between odontogenic cyst types and age groups, scalloped borders, lesion shape, tooth displacement, root resorption, and association with an unerupted tooth. Conclusion: When odontogenic cysts seen in children and adolescents are examined with cone-beam computed tomography, the radicular cyst was the most common form and was predominated in the 13-18 years age group and in boys. Differences in terms of scalloped borders, lesion shape, tooth displacement, root resorption, and association with unerupted teeth were noticed. The knowledge of the distribution and properties of odontogenic cysts in pediatric patients will help diagnose the lesions during clinical and radiological examinations and make appropriate treatment planning.
