Critical analysis of the reporting quality of animal studies within Endodontics using the Preferred Reporting Items for Animal Studies in Endodontics (PRIASE) 2021 quality standard checklist. Int Endod J 2023; 56:1042-1062. [PMID: 37300853 DOI: 10.1111/iej.13944] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 05/07/2023] [Accepted: 06/07/2023] [Indexed: 06/12/2023]
Abstract
AIM To critically evaluate the reporting quality of a random sample of animal studies within the field of endodontics against the Preferred Reporting Items for Animal Studies in Endodontics (PRIASE) 2021 checklist and to investigate the association between the quality of reporting and several characteristics of the selected studies. METHODOLOGY Fifty animal studies related to endodontics were randomly selected from the PubMed database with publication dates from January 2017 to December 2021. For each study, a score of '1' was given when the item of the PRIASE 2021 checklist was fully reported, whereas a score of '0' was given when an item was not reported; when the item was inadequately or partially reported, a score of '0.5' was given. Based on the overall scores allocated to each manuscript, they were allocated into three categories of reporting quality: low, moderate and high. Associations between study characteristics and reporting quality scores were also analysed. Descriptive statistics and Fisher's exact tests were used to describe the data and determine associations. The probability value of .05 was selected as the level of statistical significance. RESULTS Based on the overall scores, four (8%) and 46 (92%) of the animal studies evaluated were categorized as 'High' and 'Moderate' reporting quality, respectively. A number of items were adequately reported in all studies related to background (Item 4a), relevance of methods/results (7a) and interpretation of images (11e), whereas only one item related to changes in protocol (6d) was not reported in any. No associations were confirmed between reporting quality scores and number of authors, origin of the corresponding author, journal of publication (endodontic specialty vs. non- specialty), impact factor or year of publication. CONCLUSIONS Animal studies published in the specialty of endodontics were mostly of 'moderate' quality in terms of the quality of reporting. Adherence to the PRIASE 2021 guidelines will enhance the reporting of animal studies in the expectation that all future publications will be high quality.

Abstract
Background During luxate injury many dental tissue will be involved including pulp, periodontal ligament ,mucosa, hard dental tissue and alveolar bone with affecting the nerve and dental blood supplement. Growth factors may involved in healing process after replantation of tooth in its socket and the Vascular endothelial factor (VEGF ) is a potent one that increase angiogenesis and accelerate repairing and healing of dental pulp and the supporting tissues. The study was designed to illustrate the effect of application of growth factor on healing process of luxate molar tooth of rat. Materials & Methods Twenty male Wistar rats with luxate lower right first molar teeth were included in this study. The control were injected with normal saline (0.5μl ) around the apex of mesial root .Experimental group injected with VEGF (0.5μl ). Histological assessment of physiological responses of (dental pulp, cementum, periodontal ligament (PDL) and alveolar bone in both control and experimental groups with Receptor activator of nuclear factor kappa-Β ligand (RANKL) expression evaluation were recorded during the healing period in the examined tissue.

Observation periods before tooth movement in orthodontic patients who have experienced mild-to-moderate dental trauma: a scoping review of current evidence. J World Fed Orthod 2022; 11:59-68. [PMID: 35184986 DOI: 10.1016/j.ejwf.2021.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Revised: 12/29/2021] [Accepted: 12/29/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Guidelines for orthodontic patients that have experienced mild-to-moderate dental trauma recommend an observation period before beginning or resuming tooth movement, but they appear to be based on limited evidence. OBJECTIVES This scoping review examines available research on recommended observation periods before beginning or resuming tooth movement for orthodontic patients that have experienced mild-to-moderate dental trauma. The extent of research, methodologies used, outcomes reported, and justification for recommended observation periods were reviewed to identify any gaps in current knowledge. DESIGN Online databases were searched to identify papers published from 1950 to September 2021. Two publications, one from Sweden and one from Israel, reported dental outcomes of tooth movement with versus without observation periods for orthodontic patients that had experienced trauma. The risk of bias was assessed using the Cochrane Risk of Bias in Non-Randomised Studies of Interventions (ROBINS-1) tool. RESULTS One article was published in 1982, and the other in 1991. Both were observational retrospective cross-sectional studies of orthodontic patients with a history of mild-to-moderate trauma to permanent teeth (uncomplicated crown fracture, concussion, subluxation, luxation), ranging in age from 7 to 16 years. The studies listed a variety of outcomes, including clinical exams, electric pulp testing, and analysis of periapical or panoramic radiographs for signs of root resorption. CONCLUSIONS The identified articles lack sufficient evidence to determine an appropriate observation period after mild-to-moderate trauma before beginning or resuming orthodontic treatment. High-quality research is needed to better define appropriate observation periods before beginning or continuing orthodontic treatment for mildly to moderately traumatized teeth.

Periodontal ligament repair after active splinting of replanted dogs' teeth. Dent Traumatol 2021; 37:758-771. [PMID: 34198370 DOI: 10.1111/edt.12698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 05/19/2021] [Accepted: 05/20/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND/AIM The high rate of root resorption resulting from tooth replantation represents a serious clinical problem. In order to prevent ankylosis and replacement resorption, the contemporary literature highlights the importance of using a flexible stabilization for traumatized teeth. For this purpose, orthodontic devices may be promising for obtaining a better prognosis and periodontal repair. The aim of this study was to evaluate the effect of an active splinting protocol with controlled force in dog's teeth following replantation. MATERIAL AND METHODS Sixty premolar roots from three dogs were used. They were submitted to endodontic treatment, hemisected, atraumatically extracted and subsequently replanted. They were divided into four groups: Passive Stabilization (n = 20)-after 20 min in a dry medium; Active Stabilization (n = 20)-after 20 min in a dry medium; Negative control (n = 10)-immediate replantation and passive Stabilization; and Positive control (n = 10)-90 min of extra-alveolar time and passive Stabilization. The samples were collected and submitted to histologic processing. They were then evaluated for the count of inflammatory cells, expression of neurotrophin 4, osteoclasts, apoptotic cells and collagen fibres. The results were submitted to ANOVA or Kruskal-Wallis statistical tests followed by Tukey or Dunn post-tests (α = 5%). RESULTS Passive Stabilization with orthodontic brackets without traction used after replantation had the highest number of inflammatory cells (p = .0122), osteoclasts (p = .0013) and percentage of collagen fibres in the periodontal ligament (p < .0001) when compared to Active Stabilization with orthodontic brackets applying amild tensile force. Neurotrophin 4 had no statistically significant difference (p = .05), regardless of the treatment. The apoptotic cells count revealed statistical differences (p < .0001) between Active Stabilization (189.70 ± 47.99) and Positive Control (198.90 ± 88.92) when compared to Passive Stabilization (21.19 ± 32.94). CONCLUSION The active splinting protocol using orthodontic appliances generating a light and controlled force favoured periodontal ligament repair of replanted teeth.

In Vivo Biological Evaluation of Orthodontically Moved Incisors after Replantation. ACTA ACUST UNITED AC 2020; 56:medicina56090421. [PMID: 32825215 PMCID: PMC7558910 DOI: 10.3390/medicina56090421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 08/06/2020] [Accepted: 08/14/2020] [Indexed: 11/17/2022]
Abstract
Background and Objectives: There is still considerable controversy regarding the possibility of submitting replanted teeth to orthodontic movement (OM). The purpose of the present study was to evaluate the tissue response after orthodontic movement on replanted teeth. Materials and Methods: Sixty Wistar rats were randomly assigned to four groups (n = 15): G1, replantation without OM after 30 days; G2, replantation with OM after 30 days; G3, replantation without OM after 60 days, and G4, replantation with OM after 60 days. The maxillary left central incisors were extracted and the teeth were stored in milk media. After 30 min, the teeth were replanted and fixed with non-rigid immobilization. All specimens were observed after 30 and 60 days of replantation and then subdivided into two subgroups (with OM or without OM). The animals were euthanized after seven days of the OM started, and the maxillary bone blocks were processed for histological evaluation. Results: The histological results showed periodontal ligament repair in both periods studied without OM; however, ankylosis and root resorption was seen in all orthodontically moved teeth. Conclusions: The orthodontic movement did not favor tissue response in all replanted teeth, regardless of the experimental periods.
