Objective: The aims of this study were to investigate cephalometric mandibular dimensions in growing Anatolian Turkish children and to identify the periods of rapid growth for boys and girls. Furthermore, the secondary aim was to compare obtained values with published standards in the literature.
Methods: A total of 528 pretreatment lateral cephalometric radiographs, grouped according to age and sex, were analyzed. Effective mandibular length, ramus height, and corpus lengths were comparatively evaluated within age groups for boys and girls and between sexes for the same age group. Data acquired from this study were compared with American, Canadian, Chinese, and European norms. Growth curves for mandible were constructed for each sex group.
Results: Effective mandibular length was almost always significantly longer in boys, except for 9- and 12-year-age groups. Effective mandibular length in girls increased significantly between ages 8 and 10, 10 and 12, and 11 and 13 years, while in boys between ages 8 and 10, 9 and 11, and 13 and 15 years. Turkish girls had significantly shorter effective mandibular lengths than American girls at age 14. No significant difference was found between Turkish and Chinese girls and boys. Turkish girls and boys had significantly shorter corpus lengths from their Norwegian counterparts at age 12.
Conclusion: Except for 9- and 12-year-age groups, effective mandibular length was almost always significantly longer in boys compared to the girls. It is suggested to use norm values from more recently conducted studies and which are representative of the studied population. Growth curves can be used to predict the approximate mandibular dimensions at a particular age.

Purpose: This study aimed to evaluate the impact of a metal artifact reduction (MAR) algorithm on cone-beam computed tomography (CBCT) scans of titanium and zirconia implants, both within and outside the field of view (FOV).
Materials And Methods: In this study, a dry human mandible was positioned in a CBCT scanner with only its left quadrant included in the FOV. Each type of implant (titanium and zirconia) was placed once in the right second premolar extraction socket and once in the left second premolar extraction socket of the mandible.

Florid osseous dysplasia (FOD) is a rare, benign fibro-osseous lesion primarily involving the mandible and maxilla, with a higher prevalence in middle-aged women of African or Asian descent. This article presents a case of mandibular FOD complicated by secondary infection, emphasizing clinical presentation, diagnostic challenges, and treatment strategies. The unique radiographic features of FOD necessitate careful differential diagnosis to prevent misdiagnosis with other jaw lesions.

Objective: The aim of this retrospective study was to compare the effects of the Twin block and Herbst appliances on the mandibular trabecular pattern using fractal dimension analysis (FDA) of panoramic radiographs (PRs).
Methods: The PRs of 50 subjects with skeletal Class II malocclusion who underwent the Twin block (T-group, average age: 11.63±0.

Objective: This study aimed to evaluate the skeletal, dental, and soft tissue effects of the nickel titanium memory Leaf Expander in a growing sample of patients with unilateral posterior crossbite compared with a control group using digital models and lateral cephalometric radiographs.
Methods: The research included a total of 24 patients, 12 of whom were treated and 12 untreated. The Leaf Expander group consisted of 4 males and 8 females (mean age= 8.

Objectives: The aim of this study was evaluate the effect of Platelet-Rich Fibrin (PRF) in patients after mandibular third molar extraction through an analysis of the most current literature on systematic reviews and meta-analyses.
Data, Sources And Study Selection: By using computer-assisted search technology, we comprehensively searched several reliable databases, such as China National Knowledge Infrastructure (CNKI), WanFang Data, the Chinese biomedical literature database, PubMed, Web of Science, EMBase, and the Cochrane Library, and performed a systematic retrospective meta-analysis on all of the collected studies on the therapeutic effects of PRF on patients after mandibular third molar extraction. A total of nine meta-analyses were performed in this study, and all nine studies were rated as high quality on the basis of the AMSTAR 2 criteria.
