A preliminary study and hypothesis of the etiology of root caries is presented with appropriate data suggesting that biodental engineering factors (BEF) be introduced into the equation that is generally accepted in the formation of all caries. Principally, because of the rapid progression and location of root caries, BEF in addition to bacterial plaque and suitable substrate contribute to the development of these unique lesions. The dominant and most significant factors recognized by bioengineers are tooth flexure, stress concentration, stress corrosion, and piezo-electricity. All of these factors interplay during the dynamics of occlusal activity causing the loss of tooth substance. A new and revised model is being presented that provides a basis for the etiology of root caries.

This study aims to review and analyze the impact of light-emitting diode (LED) photobiomodulation (PBM) therapy on orthodontic tooth movement. This non-invasive technique is proposed to reduce time-related side effects, such as white spot lesions, dental caries, and root resorption. Five studies were included in the review, comprising two animal studies (ages 10 and 12 weeks) and three human studies (ages ranging from 15 to 17 years).

Objectives: This study aimed to compare the marginal adaptation of a cold ceramic (CC) sealer with the single-cone obturation technique with that of an AH-26 sealer with the lateral compaction technique in single-canal teeth.
Materials And Methods: In this in vitro experimental study, the root canals of 24 extracted single-rooted single-canal teeth were instrumented to F3 files by the crown-down technique and randomly assigned to 2 groups (n = 12). The root canals were obturated with a CC sealer and single-cone obturation technique with 4% gutta-percha in group 1 and with an AH-26 sealer and lateral compaction technique with 2% gutta-percha in group 2.

Department of Endodontics, Qingdao Stomatological Hospital Affiliated to Qingdao University, Qingdao, Shandong province, China. Electronic address:
Introduction: Traditional access cavity preparation involves removing the roof of the pulp chamber and smoothing the dentin bulges at the root canal orifice, thereby creating straight-line access. However, this may damage more healthy dental tissue and reduce the tooth's fracture resistance. This case series presents a novel minimally invasive endodontic protocol for one maxillary canine and four mandibular premolars, which required root canal therapy due to labial/buccal cervical decay that caused pulpitis or periapical periodontitis.

In dental practice, there are two major diseases: dental caries and periodontal disease. Although dental treatment techniques have advanced along with advances in dental materials, some diseases such as root surface caries and horizontal bone resorption have not yet achieved satisfactory treatment results. Since these diseases are infections caused by oral bacteria, we believe that materials with long-lasting antimicrobial properties would help control these diseases.

Background And Aim: This study aims to evaluate the efficacy of different endodontic irrigants employed in the lesion sterilization and tissue repair (LSTR) technique.
Methods: Forty children aged 4-8 years having at least one primary molar with irreversible pulpitis/pulpal necrosis indicated for pulpectomy were included. Participants were randomly divided into three test groups (Group A, B, and C) and one control group (Group D).
