Endodontic treatments on permanent teeth in pediatric patients aged 6-12 years old.

Backgroud/purpose: The prevalence of carious lesions and traumatic injury in individuals between ages 6 and 12 is high. This study aimed to characterize pediatric patients aged 6-12 treated in the endodontic clinic and investigate the prevalence and patterns of their provided endodontic treatments.

Materials And Methods: Clinical and radiographic records of patients (ages 6-12) referred to the postgraduate Endodontics clinic from June 2017 to June 2020 were reviewed.

Long-Term Effectiveness of Physical Exercise-Based Swallowing Interventions for Older Adults with Dementia in a Day-Care Center.

Swallowing safety is one of the top health concerns of dementia. Coughing and choking (coughing/choking) are signs of impaired swallowing safety. This study aimed to investigate the effectiveness of regular physical exercise-based swallowing intervention for reducing coughing-choking at the dementia day-care center.

Surgical management of lateral lesions with intentional replantation in single-rooted mandibular first premolars with radicular groove: 2 case reports.

Background: The authors' aim was to describe 2 endodontically treated mandibular first premolars with apical and mesiolingual radiolucencies on radiographs with different approaches that were resolved with intentional replantation.

Case Description: In case 1, a 58-year-old man reported biting sensitivity on endodontically treated mandibular first premolar with good quality restorations. A periapical radiograph (PAX) and cone-beam computed tomography (CBCT) image revealed 2 low-density areas located at the apical and mesiolingual aspects of the root.

Comparing the incidence of postoperative pain after root canal filling with warm vertical obturation with resin-based sealer and sealer-based obturation with calcium silicate-based sealer: a prospective clinical trial.

Objective: This prospective clinical study compares postoperative pain after single-visit, non-surgical root canal treatment of teeth with irreversible pulpitis using two different root canal filling techniques.

Material And Methods: All cases were treated by endodontic residents with a standardized protocol (minimum apical size 35) and filled with one of the two techniques: warm vertical compaction technique (WVT) with gutta percha and epoxy resin-based sealer (AH Plus Jet Root Canal Sealer, Dentsply Maillefer, York, PA, USA) or sealer-based filling technique (SBT) with single cone gutta percha and calcium silicate-based sealer (EndoSequence BC Sealer, Brasseler, Savannah, GA, USA). Surveys were given to participating patients to record pain intensity on a numeric rating scale (NRS, 0-10) at 4, 24, and 48 h postoperatively.

Spectrophotometric Analysis of Coronal Tooth Discoloration Induced by Tricalcium Silicate Cements in the Presence of Blood.

Introduction: New tricalcium silicate cements have been shown to induce less coronal discoloration. The purpose of this in vitro study was to evaluate the degree of color change induced by various silicate materials in the presence and absence of blood.

Methods: One hundred human extracted anterior single-canal teeth were sectioned to standardized root lengths, accessed, and instrumented.

The Application of "Bone Window" Technique in Endodontic Microsurgery.

Endodontic microsurgery for a tooth with a large periapical lesion and an intact cortical plate may necessitate the removal of extra bone and cause delayed or unfavorable healing. In such cases, the "bone window" technique offers excellent exposure to the operative field and preserves cortical bone without placing any additional graft material. In the reported cases, root-end surgery was performed on the maxillary and mandibular molars with a large periapical lesion.

Intra-articular etanercept attenuates pain and hypoxia from TMJ loading in the rat.

Mechanical overloading of the temporomandibular joint (TMJ) and biochemical changes, like inflammation and hypoxia, contribute to cartilage degeneration and pain associated with osteoarthritis (OA). Yet, how overloading contributes to early dysregulation of chondrocytes is not understood, limiting the development of diagnostics and treatments for TMJ OA. Hypoxia-inducible factors (HIF)-1α/2α in chondrocytes were evaluated at Days 8 and 15 in a rat TMJ pain model induced by jaw loading (1 h/day for 7 days) using immunohistochemistry and compared between cases that induce persistent (3.

Grading facial expression is a sensitive means to detect grimace differences in orofacial pain in a rat model.

Although pre-clinical models of pain are useful for defining relationships between biological mechanisms and pain, common methods testing peripheral sensitivity do not translate to the human pain experience. Facial grimace scales evaluate affective pain levels in rodent models by capturing and scoring spontaneous facial expression. But, the Rat Grimace Scale (RGS) has not assessed the common disorder of temporomandibular joint (TMJ) pain.

The Interface of Mechanics and Nociception in Joint Pathophysiology: Insights From the Facet and Temporomandibular Joints.

Chronic joint pain is a widespread problem that frequently occurs with aging and trauma. Pain occurs most often in synovial joints, the body's load bearing joints. The mechanical and molecular mechanisms contributing to synovial joint pain are reviewed using two examples, the cervical spinal facet joints and the temporomandibular joint (TMJ).
