The clinical outcomes of vital intact teeth close to large cystic lesions of endodontic origin: A prospective clinical study. Int Endod J 2024; 57:655-666. [PMID: 38411495 DOI: 10.1111/iej.14050] [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: 10/12/2022] [Revised: 01/15/2024] [Accepted: 02/06/2024] [Indexed: 02/28/2024]
Abstract
AIM To evaluate the indication of the endodontic treatment for vital intact teeth with the root apex involved in large radicular cystic lesions of endodontic origin. METHODOLOGY This prospective cohort study enrolled healthy participants with radicular cysts of endodontic origin and with the root apex of vital intact teeth involved in the bone defect, as determined by cone beam computed tomography (CBCT). Thirty-two sound vital teeth were analysed by thermal (TPT) and electric pulp tests (EPT) before surgery (T0) and 1 week (T1), 2 weeks (T2), 3 months (T3) and 6 months (T4) post-surgery. Student's t-test (p < .05) was used to compare the EPT values at baseline and T4. anova (p < .05) was used to analyse the EPT variations for all maxillary and mandibular teeth. McNemar test (p < .05) was used to compare the results according to variation in EPT values gathering by variation, no variation and no response. RESULTS At T1, 75 and 65.7% of teeth responded positively whilst 25 and 34.3% did not respond to EPT and TPT, respectively. The variation of the EPT values between T0 and T1 was observed for 50.0% of teeth, whilst no variation was noticed in 25.0% of teeth. At T4, 90.6 and 87.5% of teeth responded positively whilst 9.4 and 12.5% did not respond to EPT and TPT, respectively. At T4, variation of the EPT values between T0 and T4 was observed for 28.1%, whilst no variation was noticed in 62.5% of teeth. There were no statistical differences in EPT results between T0 and T4 (p > .05), but significant differences were observed for EPT values between T1 and T4 (p < .05), and between mandibular and maxillary teeth. The pulp sensibility of maxillary teeth worsened after surgery, before reverting progressively to T0 values, whilst no statistically significant differences were observed for mandibular teeth at the different time points. CONCLUSIONS These data support the inconsistence of the prophylactic endodontic treatment in healthy vital teeth with apex involvement in large cystic lesions of endodontic origin. Post-surgery follow-up with TPT and EPT is recommended to assess pulp status.

Abstract
Aim The aim of this study was to present and analyze detailed clinicopathological data of periapical cysts (PCs) and periapical granuloma (PG) in a cohort of 135 cases from the South Indian Population. Methodology The present study included 135 cases of PC and PG out of 2696 biopsies submitted over 3 years. The clinicodemographic data which included age, gender, location, radiographic appearance, and treatment were collected along with the histopathological examination of the biopsied specimen. Data were entered in a Microsoft Excel spreadsheet, 2021, and analyzed using SPSS software ver. 26. Results There were 71 cases of PG and 64 cases of PC. The mean age of occurrence in PG was slightly lower than cases in PC. Irrespective of the group, there was a clear male preponderance, and maxillary permanent central incisors were most commonly affected. However, no significant difference was noted. Radiographically, PC significantly showed more well-defined corticated radiolucent lesions compared to PG where most cases were ill-defined (69.01%). Histologically, all cases showed classic features for diagnosis with additional histological characteristics which may aid in diagnosis. Conclusion PG was more common than PC. There was a predilection for the male gender in both lesions. The actual incidence of these lesions would be actually high, as some cases are lost to private practitioners, and not all the lesions are submitted for histopathological examination.

Abstract
Paradental cyst (PC) is an uncommon type of odontogenic cyst of inflammatory origin, which develops near the cervical margin of the outside of the root of a vital tooth. The category of paradental cyst includes the buccal bifurcation cyst, which is found in the buccal area adjacent to the mandibular first or second molars in children. A conclusive diagnosis of a PC needs to correlate the surgical, radiographic, and histologic findings. When strict diagnosis is neglected, they can be easily misdiagnosed and mistreated. PCs associated with mandibular first and second molars and those associated with the mandibular third molar may have slightly different clinical manifestations but have almost completely different treatment principles due to the distinction in location. For the third molars, removal of both the tooth and the cyst is preferred. However, when the first or second molars are affected, it may be advisable to perform enucleation of the lesion while preserving the associated tooth. There are also more conservative methods to retain vital permanent teeth within the mandibular arch. Additionally, the cyst wall primarily consisted of granulation tissue firmly attached to the periodontal ligament space. The exact origin of these cysts was a subject of ongoing debate, but they were believed to primarily arise from either the reduced enamel epithelium or the inflammatory proliferation of junctional/sulcular epithelium, which originate from the superficial mucosa during tooth eruption. The aim of the present review was to update information on clinical manifestations, diagnosis and treatment strategies of cysts and discuss their pathogenic mechanisms. Raising familiarity with the distinctive features is beneficial for accurately diagnosing these lesions and effectively caring for the patients.

Abstract
Aim This case report aims to describe the importance of early diagnosis, various clinical features, and management of radicular cyst with primary mandibular molar. Background Radicular cyst is an odontogenic inflammatory cyst in origin seen more frequently in permanent dentition and rarely in the primary dentition. It can develop due to pulp injuries or pulp necrosis caused by deep dental caries or dental trauma. It may adversely affect the normal development and eruption of the permanent succedaneous teeth. Case description We report a case of radicular cyst in association with the primary mandibular molar and its therapeutic management. Conclusion The efforts in diagnosing and managing radicular cyst when associated with primary teeth hold a good impact on a child's oral health status. Good amount of bone healing and development of the succedaneous permanent tooth bud in its normal position were observed when managed appropriately. Clinical significance Early diagnosis, proper treatment planning, appropriate management, and regular follow-ups of radicular cyst in primary dentition hold great importance for pediatric dentists as well as general dentists in routine dental practice.

Abstract
Objectives The aim of the current study was to identify the expression of P63 and its relation to odontogenic epithelial cell proliferation, severity of the inflammatory infiltrate and size of radicular cysts (RCs). Methods In this retrospective cross-sectional study, 30 cases of paraffin-embedded RCs were randomly selected from the archive. P63 and Ki-67 expression was assessed by immunohistochemistry. Results Epithelial P63 expression was absent in four (13.3%), weak in 10 (33.3%), and moderate in 16 (53.3%) cases. In the connective tissue wall of RC, P63 expression was absent in two (6.7%) cases, weak in 24 (80.0%) cases, and moderate in four (13.3%) cases. Ki-67 was found to be weakly expressed in 12 (40.0%) cases, moderately expressed in 13 (43.3%), and strongly expressed in five (16.7%) cases. No correlation was found between Ki-67 expression in odontogenic epithelium and P63 expression in the odontogenic epithelium (rho = 0.110, p = .563) or fibrous capsule (rho = 0.160, p = .399). Nevertheless, we found a positive correlation between Ki-67 expression in the odontogenic epithelium and the size of the RC (rho = 0.450, p = .013). The inflammatory infiltrate was negatively correlated with P63 expression in the odontogenic epithelium (rho = -0.428, p = .018), and with the size of cysts (rho = -0.728, p < .001). Conclusions There is a high expression of P63 throughout the odontogenic epithelium and connective tissue capsule of the RC. P63 expression in the odontogenic epithelium is negatively correlated with the degree of the inflammatory infiltrate but not with epithelial cell proliferation or the size of the cyst.

Abstract
A radicular cyst is the most typical odontogenic cyst affecting the human jaws. A radicular cyst is frequently asymptomatic and is discovered accidentally during a radiological procedure. Radicular cyst most commonly occurs during the third and fourth decades of life. The patient affected by a radicular cyst usually gives a history of trauma, and they may even not be aware of the occurrence of the traumatic episode. Such a case of a Radicular cyst that occurred in a 22-year-old-young female who did not follow up further for root canal treatment was radiographically evaluated in three-dimensional view with the help of cone-beam computed tomography.

Abstract
Radicular cysts are the most common cystic lesions in the oral cavity. Radicular cysts have a rare occurrence in the primary dentition. Radicular cysts arising from deciduous teeth are reported to occur in the age range of 3–19 years with a male predominance. The etiological factor is long-standing dental caries and dental trauma. The present case report describes the inflammatory radicular cyst involving the deciduous mandibular second molar. Surgical management includes enucleation of the cyst along with mandibular second premolar in a 5-year-old female patient. The surgical cavity was closed by an obturator appliance to maintain the patency. Eventful healing was seen after 3 months of follow-up.

Abstract
Background To evaluate the morphology and immunohistochemical expression of MMP-9, TIMP-3, COL-I, TNF-alfa and COX-2 in the dentinopulp complex of restorations with self adhesive composite (Vertise Flow/Kerr) compared with conventional resin composite with self-etching adhesive (Filtek Z250/3M ESPE and Clearfil SE Bond/Kuraray-Noritake). Material and Methods A randomized, controlled, double-blind, split-mouth, two-arm clinical trial was conducted. Twenty-seven volunteers with third molars indicated for extraction received two deep class I restorations, one with each material. The morphology and immunohistochemical expression were measured at 15 days after the restorative procesures. The data were submitted to the Fisher`s Exct test (α=0.05). Results Through morphological analysis, a slight disorganization of the odontoblastic layer was visualized, along with a slight inflammatory infiltrate in the VERT and CSEB groups (p< 0.05). In immunohistochemical analysis, TNF-alpha, MMP-9, TIMP-3 and COX-2 demonstrated more cases of positive pulp labeling. Conclusions Self-adhesive resin composite and conventional resin composite with a self-etching bonding agent promoted slight alterations in the dentin-pulp complex, indicating a repair ability and reversibility of the inflammatory process against aggressions of the adhesive restorative procedure. Key words:Immunohistochemistry, inflammation, randomized clinical trial, self-adhering composite, dentistry.

Abstract
OBJECTIVES We aimed to determine the immunolocalization patterns of the interleukin (IL)-6 signaling complex in epithelialized and non-epithelialized apical lesions of endodontic origin (ALEOs). MATERIALS AND METHODS Epithelialized (n = 8) and non-epithelialized (n = 7) ALEOs were obtained from teeth with indication of extraction in patients with clinical diagnosis of apical periodontitis. All tissues were subjected to routine processing for histopathologic examination and primary antibodies for IL-6, IL-6 receptor (R), and glycoprotein (gp)-130 were used for immunohistochemistry and double immunofluorescence co-localization. RESULTS IL-6, IL-6R, and gp-130 were immunolocalized in endothelial cells and mononuclear leukocytes in a diffuse pattern within the connective tissue of epithelialized and non-epithelialized ALEOs. In the epithelialized lesions, two different patterns were identified: IL-6 signaling complex was localized within the proliferating epithelium in a diffuse intracellular pattern and in a cell membrane localization pattern within the mature epithelial lining, showing a decreased intensity towards the surface layers. CONCLUSIONS IL-6, IL-6R, and gp-130 localized to mononuclear inflammatory cells, vascular endothelial cells, and immature proliferating epithelia in a diffuse pattern and in mature lining epithelia in a localized cell membrane pattern, supporting a role for epithelial proliferation during cyst formation. Additional cell membrane co-localization of IL-6 receptor complex suggests classic signaling involvement in addition to trans-signaling.

This paper aims to report a case in which central giant cell granuloma (CGCG) mimicked a periapical lesion of endodontic origin. An 18-year-old female patient was referred for diagnosis and treatment of extensive radiolucent periapical lesion involving 31, 32, 33, 34 and 35 teeth. Clinically, the patient presented slight facial asymmetry and healthy teeth on the affected side with positive response to thermal vitality tests. Thus, an incisional biopsy was performed, which presented a histopathological picture characteristic of a CGCG. The endodontic treatment of the involved teeth was followed by surgical curettage of the lesion. After two years of follow-up, the patient was asymptomatic, with marked improvement in mandibular symmetry and adequate healing of the lesion. Therefore, the diagnosis of radiolucent periapical lesions must include lesions of endodontic and non-endodontic origin for better treatment planning and execution.

Abstract
Endodontic microsurgery is a predictable and successful procedure when using techniques that have been developed over the past several years. One of the steps during surgery involves curettage of the entire lesion. However, there are cases in which the lesion has advanced to invade anatomic structures like the nasal fossa, maxillary sinus, mandibular canal, neighboring vital teeth, or through and through to the palate. These lesions make endodontic microsurgery difficult for the operator to execute and have inherent risks to the patient. Selective curettage is a conservative approach to treat such cases by removing approximately 50%-70% of the granulomatous tissue while avoiding complications and damage to the neighboring structures. Three-dimensional cone-beam computed tomographic imaging, 2-dimensional periapical radiographs, and clinical follow-ups of the selective curettage lesions showed complete or incomplete (scar tissue) healing in all cases with no untoward results.

[PMID: 32112663 DOI: 10.1111/odi.13317] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2019] [Revised: 02/24/2020] [Accepted: 02/24/2020] [Indexed: 01/17/2023]
Abstract
AIM To analyze the heterogeneity of fibroblasts isolated from the fibrous capsules of radicular cysts and explore the effects of fibroblast subsets on bone destruction. METHODOLOGY Radicular cysts were divided into groups according to varying perilesional sclerosis identified by radiograph. Colony-forming units (CFUs) were isolated from the fibrous capsules of cysts, by which Trap + MNCs were induced, and the expression of osteoclastogenesis-related genes was compared among groups by real-time PCR. The variances in gene profiles of CFUs were identified by principal component analysis, and then, CFUs were divided into subsets using cluster analysis. The induction of Trap + MNCs and related gene expression was compared among subsets, and osteoclastogenic induction was blocked by IST-9 or bevacizumab. The fibroblast subsets in cysts were investigated by retrospective immunostaining with IST-9, VEGF-A, and CD34. A fibroblast subset that underwent gene editing by CRISPR/Cas was injected into the site of bone defects in animal models, and the in vivo effects on osteoclastogenesis were investigated. RESULTS The fibroblast CFUs isolated from radicular cysts with perilesional unsclerotized cysts induced more Trap + MNCs than those with perilesional sclerotic cysts (p < .05). Most fibroblast CFUs from unsclerotized cysts belonged to Cluster 2, which induced more Trap + MNCs (p < .05) and highly expressed genes facilitating osteoclastogenesis; these results were different from those of Cluster 1 (p < .05), in which most CFUs were isolated from perilesional sclerotic cysts or controls (p < .05). The high expression of EDA + FN and VEGF-A was investigated in both the fibroblasts of Cluster 2 and the fibrous capsules of unsclerotized cysts (p < .05), and the number of Trap + MNCs induced by Cluster 2 was decreased by treatment with IST-9 and bevacizumab (p < .05). Consistently, EDA exon exclusion significantly decreased the osteoclastogenic induction of fibroblasts from Cluster 2 in vivo (p < .05). CONCLUSION The fibrous capsules of radicular cysts contain heterogeneous fibroblasts that can form subsets exhibiting different effects on osteoclastogenesis. The subset, which depending on the autocrine effects of EDA + FN on VEGF-A, mainly contributes to the osteoclastogenesis and bone destruction of radicular cysts. The regulation of the proportion of subsets is a possible strategy for artificially interfering with osteoclastogenesis.

Abstract
AIM To analyse the effects of the alternatively spliced fibronectin (FN) gene and its isoforms on osteoclastogenesis in radicular cysts. METHODOLOGY Specimens of radicular cysts were collected surgically from 22 patients whose radiolucent periapical areas were measured on digital panoramic radiographs before surgery. The associations between the radiolucent areas and FN isoforms, vascular endothelial growth factor (VEGF) expression or micro-vessel density, as well as the relationships amongst them, were analysed by immunohistochemical staining using the antibodies IST-9, BC-1, P1F11, VEGF and CD34. Fibroblasts isolated from those specimens were used to induce Trap + MNCs, and the effects of induction were assessed by blocking FN containing extra domain A (EDA + FN), COX-2 or VEGF in vitro. The effects of EDA exon knockout using CRISPR/Cas system were also assessed. Quantitative PCR was used to analyse relative expression of FN isoforms and osteoclastogenic genes. Data were analysed using linear regression, Spearman's rank correlation analysis, chi-square test and Student's t-test; P < 0.05 was considered significant. RESULTS Micro-vessel density and EDA + FN staining were positively associated with the size of radiolucent periapical areas (mm2 ; P < 0.05), consistent with a positive association between Trap + MNCs and VEGF expression in fibroblasts (P < 0.05). Blocking the interaction between EDA + FN and fibroblasts inhibited Trap + MNC formation. In addition, EDA exon knockout decreased VEGF expression and inhibited Trap + MNC formation to the extent of blocking VEGF by bevacizumab, but osteoclastogenic induction was restored by recombinant VEGF. Using retrospective clinicopathological data, VEGF staining was shown to be positively associated with EDA + FN staining, micro-vessel density and the size of radiolucent areas (P < 0.05). CONCLUSION In fibrous capsules of radicular cysts, the alternatively spliced isoform EDA + FN generated by fibroblasts stimulated VEGF expression via an autocrine effect and then facilitated osteoclastogenesis. Both blockage of VEGF and EDA exon knockout could be used to inhibit bone destruction.

Abstract
Summary
Background/Aim: Cysts which appear in the orofacial region are represented as common pathological changes which underlying mechanism of development is still not fully clear. In recent years, a dominant role in the pathogenesis of cysts belongs to the immunopathological reactions. It is assumed that the loss of bone in cysts is due to the presence of complementary cascades, prostaglandins synthesis and numerous neutrophil granulocytes. The main objective was to determine the levels of Ig G, A and M in serum and saliva of patients with radicular, residual and periodontal cysts before and after the surgical treatment.
Material and Methods: The study included 185 patients, of which 150 patients were diagnosed with inflammatory cysts (radicular, periodontal and residual), while the control group consisted of 35 patients without presence of inflammatory cyst. The immunoglobulins were determined prior to the surgical removal of the cyst and one month after the procedure, when complete clinical wound healing was observed. The levels of these immunological markers were compared to each other before and after the cyst extirpation, taking into consideration the different cyst types. A comparison was also made between both examination and control group.
Results: The difference of the basic values of the immunoglobulins before therapy and the basic values of the immunoglobulins in the control group was statistically significant only in the group of residual and periodontal cysts for IgG and IgM The difference of the average values of immunoglobulins (IgG, IgA and IgM) in the group with residual cysts before and one month after therapy is statistically significant (p=0.0000; p=0.0371; p=0.0276). A significant difference was registered in IgA among the three examined groups one month after surgical intervention.
Conclusions: The levels of serum immunoglobulins in patients with inflammatory cysts were elevated before the treatment and dropped after the cyst removal. This study suggests that the IgA, IgG and IgM may play an important role in the occurrence, development and persistence of the cystic lesions.

Abstract
The objective of this study was to evaluate the expression of matrix metalloproteinase 9 (MMP-9) and transforming growth factor beta (TGF-β1) in periapical lesion samples correlated with the intensity of the inflammatory infiltrate and thickness of the epithelial lining. Forty-five cases of periapical lesions (23 periapical granulomas and 22 radicular cysts) were subjected to morphological and immunohistochemical analyses using anti-MMP-9 and anti-TGF-β1 antibodies. The data were analyzed using the following tests: non-parametric Mann-Whitney, chi-square, Fisher's exact test and Spearman's correlation test (P<0.05). Analysis of inflammatory infiltrate revealed that 78% of periapical granulomas presented infiltrate grade III, in contrast with 32% of radicular cysts (P<0.001). Morphological evaluation of the epithelial thickness in radicular cysts revealed the presence of atrophic epithelium in 86% of the cysts. The immunostaining of MMP-9 was score 2 in 67% of the granulomas and 77% of the cysts. Both lesions were predominantly score 1 for TGF-β1. Significant differences were confirmed between the expression scores of TGF-β1 and MMP-9 in periapical granulomas (p = 0.004) and in radicular cysts (p < 0.001). Expression of TGF-β1 was different for periapical granulomas and radicular cysts. This immunoregulatory cytokine seems more representative in asymptomatic lesions. The extracellular matrix remodeling process dependent on MMP-9 seems to be similar for both periapical granulomas and radicular cysts. TGF-β1 and MMP-9 may play an important role in the maintenance of periapical lesions.

Abstract
BACKGROUND Odontogenic cysts (OC) are the most frequent lesions of the jaws and their constant epidemiological update is necessary and indispensable. Therefore the principal objective of this report was To determine prevalence and clinical-demographical characteristics of OC in a Mexican sample. MATERIAL AND METHODS 753 cases of OC coming from the archive of a head and neck histopathological teaching service, from January 2000 to December 2013, were included. OC cases were re-assessed according 2005 WHO classification. Chi square test was used to establish possible associations (p<0.05IC95%). RESULTS From 753 OC, 369 were female and 384 male; 52.9% of them were in their 2nd- 4th decade of life. The most common location (41%) was the mandibular posterior area. Radicular cysts were more frequent in maxillary anterior zone of females (p 0.0002) at their fourth decade of life. Dentigerous cysts were more frequent in the mandibular posterior zone of males (p 0.0000) in their second decade of life. Six cases of periodontal lateral cyst; 4 cases of paradental cysts; 4 eruption cysts and 4 cases of adult gingival cyst, as well were identified. CONCLUSIONS Radicular cyst and dentigerous cyst are the most prevalent odontogenic cyst in this Mexican sample. Due to their etiology, dental pulpar necrosis and impacted teeth, radicular cyst and dentigerous cyst could be prevenible. Therefore, it is necessary to establish preventive strategies to diminish dental decay and programs of prophylactic extractions of impacted teeth, to in consequence decrease the prevalence of odontogenic cysts. Key words:Cyst, dentigerous cyst, mexican, odontogenic cyst, radicular cyst.
