Purpose: To compare the maximum occlusal force in endodontically treated teeth and their vital contralateral counterparts and to evaluate the intraoral factors affecting them.
Materials And Methods: Thirty adult participants presented with an endodontically treated tooth and its vital contralateral counterpart were recruited, with 15 males and females in each group. Maximum occlusal forces were measured using a wireless sensor network occlusal force recorder, and the mean maximum occlusal force of endodontically treated teeth was compared with that of their vital contralateral counterparts. Multiple-factor ANOVA was used to examine the association between various clinical factors and maximum occlusal force.
Results: The mean maximum occlusal force for endodontically treated teeth was significantly higher than their vital counterparts (215.44 ± 74.11N and 202.40 ± 70.67N, respectively) (P < 0.001). Among the clinical factors, the maximum occlusal forces were significantly influenced by the location of teeth (P < 0.01) and the crown root ratio (P = 0.01). Upon further analysis of endodontically treated teeth and control groups, the location of teeth was identified as a sole factor associated with maximum occlusal force, with P < 0.05.
Conclusion: The maximum occlusal forces for endodontically treated teeth were statistically significantly higher than those of their corresponding vital contralateral teeth.

Occlusal tactile acuity (OTA) and bite force are essential components of the sensorimotor control of oral behaviors. While these variables have been studied independently, it has not yet been revealed whether compressive force impacts the occlusal perception mediated by the mechanoreceptive afferents in the periodontal ligament. The present study examined the effect of repetition and maximum bite force on OTA by testing nine aluminum foils of different thicknesses together with a sham test with no foil, three times each, in randomized order in 36 healthy individuals.

Myofascial pain is one of the common symptoms in patients with temporomandibular joint disorders (TMD). Occlusal splint (OS) and masticatory muscle trigger point (TP) local injections are primary treatment options. We aimed to investigate the effects of these treatments using clinical and elastography measures.

Aim: The purpose of this study is to investigate the interchangeability of newly acquired, short-term used, and long-term used semi-adjustable articulators.
Materials And Methods: Metal analogs of partially dentate maxillary and mandibular arches were mounted on twelve semi-adjustable Stratos 300 articulators, divided into three groups based on usage over time: New, short-term used (<2 years), long-term used (>2 years) articulators. Each articulator was calibrated according to manufacturer guidelines, ensuring consistency.

Aim: The present case-control study was planned to assess the comparative efficacy of resin-modified calcium silicate, resin-modified glass ionomer, and Dycal as pulp capping agents in indirect pulp therapy for deeply carious young permanent molars.
Materials And Methods: Thirty deeply carious young posterior teeth were treated by indirect pulp therapy. During the treatment, the cavity floor was lined with TheraCal or resin-modified glass ionomer cement (RMGIC) in the study group and with Dycal (control group) followed by GC IX and composite restoration.

Objectives: To compare the stress distribution and crack propagation in cracked mandibular first molar restored with onlay, overlay, and two types of occlusal veneers using two different CAD/CAM materials by Finite Element Analysis (FEA).
Materials And Methods: A mandibular first molar was digitized using a micro CT scanning system in 2023. Three-dimensional dynamic scan data were transformed, and a 3D model of a cracked tooth was generated.
