Cortical thicknesses of alveolar crest and mandibular canal cortical borders (buccal, lingual, apical, and coronal) in each mandibular posterior teeth region were measured.

Three-Dimensional Evaluation of Autogenous Ramus Block Graft Donor Site and Its Relation to Mandibular Canal.

Sufficient bone volume is necessary for placing a dental implant in an ideal position. To restore severely insufficient bone volume, autogenous block graft procedures with various intraoral donor sites are presented in the literature. The aims of this retrospective study are to present the dimensions and volume of the potential ramus block graft site, and to evaluate possible effect of mandibular canal diameter and its position in relation to mandibular ramus block graft volume.

The Radiological Evaluation of Mandibular Canal Related Variables in Mandibular Third Molar Region: a Retrospective Multicenter Study.

Objectives: The aim of this retrospective study was to investigate anatomical structure of mandibular canal and the factors those increase the possibility of inferior alveolar nerve damage in mandibular third molar region of Turkish population.

Material And Methods: Overall 320 participants with 436 mandibular third molars were included from four different study centers. Following variables were measured: type and depth of third molar impaction, position of mandibular canal in relation to third molars, morphology of mandibular canal, cortication status of mandibular canal, possible contact between the third molars and mandibular canal, thickness and density of superior, buccal, and lingual mandibular canal wall, bucco-lingual and apico-coronal mandibular canal diameters on cone-beam computed tomography scans.

Dental caries and associated salivary biomarkers in patients with cystic fibrosis.

Purpose: To evaluate the caries status of the Cystic fibrosis (CF) children and adolescents with the comparation of some biochemical markers, secretory-immunoglobulin-A (sIgA), and antimicrobial peptides in the saliva.

Methods: In this cross-sectional descriptive study, the approval Ethics Board was obtained. Unstimulated saliva samples were collected from CF and healthy control children (non-CF) patients.

Association between ridge morphology and complexity of implant placement planning in the posterior mandible.

Statement Of Problem: Uncertainties regarding the 3D ridge morphology of the posterior mandible can greatly increase the risk of surgical complications during dental implant placement. By using cone beam computed tomography (CBCT) imaging and a computer-guided implant treatment software program before any invasive procedure, it is possible to assess ridge morphology and understand the surgical complexity and risk level.

Purpose: The purpose of this radiological clinical study was to evaluate a large series of CBCT images to evaluate ridge shape variations along posterior mandibular edentulous regions and to clarify their associations with the level of implant planning complexity.

Treatment of Excessive Gingival Display by Using Botulinum Toxin-A Targeting Yonsei Points and Zygomatic Major Muscles.

The aim of this clinical report is to present satisfying and unsatisfying treatment results of a patient with excessive gingival display (EGD) treated via botulinum toxin injections in different time points. A 22-year-old male patient referred to the Department of Periodontology with a complaint of EGD. The patient opted the treatment with botulinum toxin-A injections.

Quantity and Quality of Intraoral Autogenous Block Graft Donor Sites with Cone Beam Computed Tomography.

Purpose: The autogenous bone block graft is regarded as the gold standard material due to reported osteoconductive, osteoinductive, and osteogenic properties. Various intraoral donor sites for autogenous block grafts are presented in the literature. The aim of this study was to radiographically evaluate the maximum dimensions, volume, and bone quality values of these sites.

In-depth morphological evaluation of tooth anatomic lengths with root canal configurations using cone beam computed tomography in North American population.

Objective: This study aimed to assess the association between tooth size and root canal morphology by using CBCT analysis.

Methodology: In this retrospective study, tooth anatomic lengths (crown and root lengths, buccolingual and mesiodistal dimensions) of 384 patients were assessed and correlated with Vertucci's root canal morphology classification. Data was analyzed for gender-related differences using the independent sample t-test, ANOVA, and the Pearson's correlation for a possible relation between anatomic lengths and canal morphology.

Levels of pro- and anti-inflammatory cytokines in cystic fibrosis patients with or without gingivitis.

Background: Inflammatory periodontal diseases are caused by interaction between gram negative, anaerobic bacteria and host response. Persistent infection of Pseudomonas aeruginosa in cystic fibrosis (CF) patients also cause increased pro-inflammatory response and the imbalance of pro- and anti-inflammatory response in brochoalveolar lavage fluid which leads to destruction of lungs. The aim of this study is to evaluate periodontal status of CF patients, to measure level of cytokines and biochemical molecules in gingival crevicular fluid (GCF), and to detect presence of P.

Ideal Dose and Injection Site for Gummy Smile Treatment with Botulinum Toxin-A: A Systematic Review and Introduction of a Case Study.

The objective of this article is to review ideal injection point and ideal dose of botulinum toxin-A injections to treat different types of gummy smile, and to present a case treated with the recommended method. An electronic search of literature was carried out by using PubMed, Embase, and Google Scholar. Reference lists of studies were also hand-searched for relevance.

Effects of clinical local factors on thickness and morphology of Schneiderian membrane: A retrospective clinical study.

Background: It was informed that the thickness of maxillary sinus membrane may be affected by the local and patient-related factors in the literature.

Purpose: The aim of this retrospective study is to evaluate factors that may have an influence of the thickness and morphology of the maxillary sinus membrane.

Materials And Methods: A total of 414 cone beam computed tomography images of 207 patients were evaluated.

The radiological evaluation of posterior superior alveolar artery topography by using computed tomography.

Background: Posterior superior alveolar artery (PSAA) is the most important limiting anatomic structure while lateral approach sinus surgeries. PSAA should be taken into consideration to avoid bleeding during preparation of bony window.

Purpose: The aim of this article was to inform topography of PSAA and to evaluate measurements of this vital structure.

Treatment of Various Types of Gummy Smile With Botulinum Toxin-A.

The objective of this article is to present 3 various types of gummy smile treated with botulinum toxin-A injection per site at Yonsei points. The patients, who visited the department to demand a more aesthetic smile, were classified according to gummy smile type: asymmetric, anterior, and mixed. Botulinum toxin-A injection at Yonsei point was considered.

Radio-Morphometric Evaluation of Greater Palatine Canal and Pterygopalatine Fossa Component: Maxillary Anesthetic Implications.

This is a retrospective analytical cross-sectional study involving 131 cone-beam computed tomography (CBCT) scans of adult (18-99 years) that assessed greater palatine canal (GPC) attributes (length, curvature angle, diameter of curvature) and the type of the trajectory of GPC-pterygopalatine fossa (PPF) component. The GPC is an important landmark that connects the oral cavity and PPF. It contains greater and lesser palatine nerves, along-with descending palatine artery and vein by extending from the inferior part of the PPF to the hard palate.
