Radiographic Assessment Of Anterior Maxillary Sites Prior To Immediate Implant Placement: A Retrospective Study On Cbct, Elissa El Alam, Abdallah Menhall, Nabil Ghosn, Pierre Lahoud

International Arab Journal of Dentistry

Objectives: The purpose of this retrospective radiographic study was to measure alveolar bone width at the alveolar crest, intraosseous root length, apical bucco-palatal bone thickness and apical bone height at the anterior maxillary teeth prior to immediate implant placement. Dehiscence and fenestration at these sites were also reported.

Methods: 50 CBCTs were included in this study. Measurements were taken on the right and left sides of the central incisor, lateral incisor, and canine using a 3d slicer program. Frequency of fenestration and dehiscence at these sites were also reported.

Results: Mean bone width at the alveolar crest of the central …

Evaluation Of Maxillary Posterior Teeth Proximity To The Adjacent Sinuses In A Turkish Subpopulation: Implications For Dental Education And Clinical Practice, Damla Yiğit, Gizem Dolaşir, Sabri Çelik, Rüya Sessiz, Raif Alan

Journal of Dentistry Indonesia

Objectives: This study aimed to evaluate the proximity of upper posterior tooth roots to adjacent sinus borders using cone-beam computed tomography (CBCT) in a Turkish subpopulation and to assess dental students’ competence in identifying this anatomical relationship. Methods: CBCT scans of 171 patients were analyzed. The vertical relationship between premolars and molar roots, and the maxillary sinus (MS) border was categorized into four types (Type 0–3). Interrater agreement between three final-year dental students and an experienced radiologist was measured. Results: Type 0 was the most frequent classification, except for first molars, where Type 2 and Type 3 predominated. MS-root distances …

An Art Of Port Wine Birthmark - A Case Report On Type Ii Sturge Weber Syndrome, Dr Sushmitha S, Dr Aravind Warrier S, Dr Dhivya Bharathi

Chulalongkorn Medical Journal

Sturge Weber Syndrome is a Phakomatoses group of neurocutaneous disorders. They manifest in the dermal, neural, ocular, and oral regions due to a mutation in the GNAQ gene. These lesions often are unilateral following the course of the trigeminal nerve.Here we present a case of 54-year-old woman with a history of glaucoma with a unilateral reddish-purple discoloration of the palate and a port-wine stain limited to the left side of her face. The clinical course of Sturge-Weber syndrome is quite complex and necessitates a multidisciplinary approach. In type 2 cases of Sturge-Weber syndrome, patients present with facial angiomas and glaucoma, …

Low Dose Cone Beam Computed Tomography Versus High Dose Cone Beam Computed Tomography In Measuring Furcation Involvements: (Diagnostic Accuracy Study), Marwa Ezz, Cairo University, Misr University For Science & Technology

Dentistry

Accurate diagnosis of furcation defect is essential in periodontal therapy planning. Cone beam computed tomography (CBCT) provides three-dimensional visualization, but higher radiation doses remain a concern. This study aims to assess and compare the diagnostic accuracy of low-dose CBCT (LD-CBCT) and high-dose CBCT (HD-CBCT) in detecting and measuring furcation defect using a pig mandible. Detection and accurate assessment of periodontal disease is important to determine the tooth prognosis and treatment. Radiographic assessment provides information about the pattern and extent of the furcation defect. CBCT provides unique 3D images used for diagnosis and treatment plans, but its use in periodontology not …

Comparison Of Pharyngeal Airway And Dentoskeletal Effects Of 2 And 4 Premolar Extraction Treatment In Adult Orthodontic Patients, Esra Genc, Ahmet Karaman

Journal of Dentistry Indonesia

Objective: This study aimed to compare pharyngeal airway and dentoskeletal effects of 2 and 4 premolar extraction treatments in adult patients separately for each gender. Methods: The study was conducted with 60 adults (26 males; 34 females) aged 18-35 years. Individuals were divided into 3 groups as non-extraction, 2-premolar extraction, and 4-premolar extraction. Pre-treatment (T0) and post-treatment (T1) dentoskeletal and pharyngeal airway measurements were performed on cephalometric radiographs. Results: A significant increase in nasopharyngeal airway (PNS-ad2) and anterior hyoid bone movement (CV3ai-H) was observed in the 4-extraction group; whereas in the 2-extraction group, inferior oropharyngeal airway (IAS) narrowing and hyoid …

A Randomized Clinical Trial, Moataz Dr. Bahaa, Abdelrahman Fahmy Dr., Hisham Elsheikh Dr., Bassam Abulnoor, Amr Amin Prof., Sherif El Bahnasy, Karim Abdelmohsen Prof

Dentistry

Introduction: The goal of using ultrasound-guided (USG) arthrocentesis is to reduce number of needle insertion attempts, which is hypothesized to reduce procedure time, postoperative pain, and consequently, limitation in range of motion. Purpose: The objective of this study was to compare the therapeutic and operative efficiency of USG Single-Puncture Arthrocentesis (SPA) Type 2 and SPA Type 2 arthrocentesis without ultrasound guidance in the treatment of temporomandibular joint (TMJ) internal derangement (ID) “disc displacement without reduction (DDWOR).” Materials and methods: A double-blinded prospective randomized clinical trial (RCT) was conducted from December 2022 to December 2023 at Ain Shams University Hospital. It …

Mandibular Lingual Concavity Evaluation Using Cone Beam Computed Tomography, Anthony L. Neely Dds, Mdentsc, Phd, Bassam M. Kinaia Dds, Ms, Dicoi, Lidya Jirjis Dds, Ms, Dalia Hasso Dds, Ms, Jonathan Zora Dds, Ms, David Van Winkle Dds, Naiomy Perez-Villanueva, Sharhdad Kazerani Dds, Ms, Samual Korkis Dds, Ms, Omar Masabni Dds, Ms, James R. Geist Dds, Ms

The Journal of the Michigan Dental Association

Dental implant placement in the posterior mandible can be impacted by the presence of the lingual concavity. Perforating the lingual cortical bone could lead to life-threatening hemorrhage/airway obstruction. The aim of this retrospective study is to examine dentate and partially edentulous mandibles to describe anatomical variations related to the lingual concavity by evaluating cone beam computed tomography (CBCT).

Centering And Shaping Abilities Of Three Different Cross-Section Rotary Systems In Curved Canals Using Cbct, Sherif Shafik

Dentistry

ABSTRACT The aim of the study was to examine the centering and shaping abilities of the E3 Azure, T Blue and XPRS rotary devices in severely curved root canals utilizing CBCT. 51 mesial roots were used in this study, then distributed into three groups of 17 mesial canals each according to the instrumentation technique: T-Blue, E3 Azure and XPS. The final apical size of instrumentation was 30/0.04 for all groups. At 2 mm, all pairwise comparisons were statistically significant, with Azure showing the highest transportation, followed by T-Blue, and XPS showing the least (p< 0.001). At 4 mm and 6 mm, Azure and T-Blue showed significantly higher transportation than XPS (p< 0.001). For XP-Shaper files, centering ratios followed a descending order from 6 mm to 4 mm and were lowest at 2 mm, with all pairwise comparisons being statistically significant (p< 0.001). it was concluded that XPS show lesser transportation and better centering ability.

Dentistry

Objective: This study aimed to compare the accuracy of condylar positioning between 2 computer-guided orthognathic surgical protocols: a waferless screw hole plate locating (WSL CPD) technique versus an occlusal splint with distal extending arms (OWDA-CPD) approach. Materials and Methods: Twenty-four patients requiring mandibular orthognathic surgery (class II or III deformities) were randomly allocated into 2 groups (n=12 each). Group I underwent a waferless protocol utilizing 3D-printed osteotomy and screw hole locating guides, while group II received an occlusal splint with distal extensions for condylar positioning. Preoperative and postoperative cone-beam computed tomography (CBCT) scans were used to assess condylar displacement in …

Assessment Of Incisive Canal Morphology And Position In A Sample Of Egyptian Population: A Cone Beam Computed Tomography Study, Sherif Shafik

Dentistry

ABSTRACT Several studies have highlighted the diversity in the anatomy of the incisive canal. Evaluation of incisive canal as well as its approximation to the maxillary incisor root is crucial before orthodontic treatment, implant placement and other surgical procedures in the anterior maxillary area. Cone beam computed tomography (CBCT) provides detailed three-dimensional information and have been used to evaluate the nasopalatine region with high accuracy along with relative safety due to low radiation exposure. Aim: The study aimed to provide analysis of the nasopalatine canal anatomy using cone-beam computed tomography (CBCT) in a sample of the Egyptian population. Materials & …
