This study observed the temperature changes in the pulp chamber during tooth preparation for a complete crown. Twelve extracted, morphologically intact human teeth were chosen: four canines, four premolars, and four molars. Six teeth, two of each, were cooled during preparation with an air-water spray; the remaining six were air-cooled. Minimal reduction of dentin using an air-water spray coolant resulted in a lowered temperature in the pulp chamber, mainly with the cross-grooved TDA diamond stones. The application of an air coolant resulted in a temperature rise in the pulp chamber.

Prevalence and morphology of middle mesial canals in mandibular first molars and their relationship with anatomical aspects of the mesial root: a CBCT analysis.
BMC Oral Health

Department of Endodontics, Shaanxi Provincial People's Hospital, Xi'an, China.
Background: This study aims to investigate the prevalence and morphology of middle mesial canal (MMC) in mandibular first molar (M1M) among a Northwestern Chinese population, and to analyze their relationship with anatomical aspects of the mesial root.
Methods: Cone beam computed tomography (CBCT) was utilized to evaluate 898 M1Ms and assess the incidence and morphology of MMC. The following parameters for M1M with or without MMC were obtained: the vertical distance between the first appearance of MMC and canal orifices (D), the distance between mesiobuccal (MB) and mesiolingual (ML) canals (D1), the buccolingual width(L1) and mesiodistal width (L2) of mesial roots, and the flatness degree(L1/L2) of mesial roots.
Evaluation of the efficiency of smear layer removal during endodontic treatment using scanning electron microscopy: an in vitro study.
BMC Oral Health

Department of Dental Science, Damascus University, Damascus, Syria.
Background: The smear layer formed during root canal instrumentation negatively affects root canal irrigation activity, which in turn can affect the treatment prognosis of endodontic treatment.
Aim: The aim of this study is to compare the efficiency of smear layer and debris removal in root canals using different irrigation protocols using scanning electron microscopy (SEM).
Materials And Methods: The quality of smear layer removal throughout the root canal was assessed in 30 intact extracted teeth divided into 3 groups according to the irrigation protocol: Group 1: 3% sodium hypochlorite (NaOCL) alternately with 17% ethylenediaminetetraacetic acetate (EDTA) was used.
Effect of pulp-chamber lateral wall thickness and number on fracture resistance in endocrown-restored molars: An in vitro study.
J Dent Sci
January 2025
Department of Cariology and Endodontology, Peking University School and Hospital of Stomatology, Beijing, China.
Background/purpose: It remains unclear how the thickness and number of pulp-chamber lateral walls (PCLWs) affects fracture resistance in endocrown-restored teeth.
Materials And Methods: 64 mandibular molars were collected and randomly divided into eight groups (n = 8). In group C (control group), the teeth were untreated.
Mouse Model of Lipopolysaccharide (LPS)-Induced Pulpitis.

Objectives: Transmitted-light plethysmography (TLP) is an objective and non-invasive pulp diagnosis method that has already been validated for applications for incisors. However, there is a demand for TLP use in the molars, it has not yet been established for this application. This study investigated the optimal light source wavelengths for TLP in premolars, to establish a pulp diagnosis system based on measuring pulpal blood flow.
