Predictor factors of 1-rooted mandibular second molars on complicated root and canal anatomies of other mandibular teeth: Hakan Aydın, Hatice Harorlı; Restor Dent Endod 2024;49(1):e2. Published online January 3, 2024; DOI: https://doi.org/10.5395/rde.2024.49.e2

Abstract PDF PubReader ePub: Objectives
This study aimed to determine the effects of 1-rooted mandibular second molar (MnSM) teeth on root canal anatomy complexities of the mandibular central incisor (MnCI), mandibular lateral incisor (MnLI), mandibular canine (MnCn), mandibular first premolar (MnFP), mandibular second premolar (MnSP), and mandibular first molar (MnFM) teeth.
Materials and Methods
Cone-beam computed tomography images of 600 patients with full lower dentition were examined. Individuals with 1-rooted MnSMs were determined, and the complexity of root canal anatomy of other teeth was compared with individuals without 1-rooted MnSMs (Group-1; subjects with at least one 1-rooted MnSM, Group-2; subjects with more than a single root in both MnSMs). A second canal in MnCIs, MnLIs, MnCns, MnFPs, and MnSPs indicated a complicated root canal. The presence of a third root in MnFMs was recorded as complicated.
Results
The prevalence of 1-rooted MnSMs was 12.2%, with the C-shaped root type being the most prevalent (9%). There were fewer complicated root canals in MnCIs (p = 0.02), MnLIs (p < 0.001), and MnFPs (p < 0.001) in Group 1. The other teeth showed no difference between the groups (p > 0.05). According to logistic regression analysis, 1-rooted right MnSMs had a negative effect on having complex canal systems of MnLIs and MnFPs. Left MnSMs were explanatory variables on left MnLIs and both MnFPs.
Conclusions
In individuals with single-rooted MnSMs, a less complicated root canal system was observed in all teeth except the MnFMs.

Apical periodontitis in mesiobuccal roots of maxillary molars: influence of anatomy and quality of root canal treatment, a CBCT study: Samantha Jannone Carrion, Marcelo Santos Coelho, Adriana de Jesus Soares, Marcos Frozoni; Restor Dent Endod 2022;47(4):e37. Published online September 19, 2022; DOI: https://doi.org/10.5395/rde.2022.47.e37

Objectives

This study aimed to evaluate the prevalence of apical periodontitis (AP) in the mesiobuccal roots of root canal-treated maxillary molars.

Materials and Methods

One thousand cone-beam computed tomography images of the teeth were examined by 2 dental specialists in oral radiology and endodontics. The internal anatomy of the roots, Vertucci’s classification, quality of root canal treatment, and presence of missed canals were evaluated; additionally, the correlation between these variables and AP was ascertained.

Results

A total of 1,000 roots (692 first molars and 308 second molars) encompassing 1,549 canals were assessed, and the quality of the root canal filling in the majority (56.9%) of the canals was satisfactory. AP was observed in 54.4% of the teeth. A mesiolingual canal in the mesiobuccal root (MB2 canal) was observed in 54.9% of the images, and the majority (83.5%) of these canals were not filled. Significant associations were observed between the presence of an MB2 canal and the quality of the root canal filling and the presence of AP.

Conclusions

AP was detected in more than half of the images. The MB2 canals were frequently missed or poorly filled.

Enhanced visualization of the root canal morphology using a chitosan-based endo-radiopaque solution: Shashirekha Govind, Amit Jena, Satabdi Pattanaik, Mahaprasad Anarasi, Satyajit Mohapatra, Vinay Shivagange; Restor Dent Endod 2021;46(3):e33.

Objectives

This study aimed to investigate the efficacy of ionic and non-ionic-based contrast media (in vitro study) and the combinatorial effect of chitosan-based endo-radiopaque solution (CERS) (in vivo study) for visualization of the root canal anatomy.

Materials and Methods

In vitro study (120 teeth): The root canal of maxillary premolars and molars (in vitro group 1 and 2 respectively, n = 60 each) were analyzed using 4 different contrast media (subgroups: Omnipaque 350, Iopamidol, Xenetix 350, and Urografin 76; n = 15 each) in combination with 5.25% sodium hypochlorite (NaOCl). Based on the results of the in vitro study, in vivo study (80 teeth) was done to compare Xenetix 350 + 5.25% NaOCl with CERS (in vivo group 1 and 2 respectively, n = 40 each) on maxillary and mandibular premolars and molars. Two endodontists used radiovisiography to assess the depth of ingress and identify the aberrant root anatomy after access cavity preparation, and after initial cleaning and shaping of canals. Kruskal-Wallis test was used for in vitro comparison (p < 0.05), and Wilcoxon signed-rank test and Mann-Whitney U test for in vivo analysis (p < 0.01).

Results

In vitro study, Xenetix 350 + 5.25% NaOCl facilitated a significant higher visualization (p < 0.05). For in vivo study, CERS had a statistically significant depth of ingress (p < 0.01), and was efficient in identifying the aberrant root canal anatomy of premolars and molars.

Conclusions

CERS facilitates better visualization of the root canal anatomy of human premolars and molars.

Surgical endodontic management of infected lateral canals of maxillary incisors: Ji-Hyun Jang, Jung-Min Lee, Jin-Kyu Yi, Sung-Baik Choi, Sang-Hyuk Park; Restor Dent Endod 2015;40(1):79-84. Published online October 10, 2014; DOI: https://doi.org/10.5395/rde.2015.40.1.79

Abstract PDF PubReader ePub

This case report presents surgical endodontic management outcomes of maxillary incisors that were infected via the lateral canals. Two cases are presented in which endodontically-treated maxillary central incisors had sustained lateral canal infections. A surgical endodontic treatment was performed on both teeth. Flap elevation revealed vertical bone destruction along the root surface and infected lateral canals, and microscopy revealed that the lateral canals were the origin of the lesions. After the infected lateral canals were surgically managed, both teeth were asymptomatic and labial fistulas were resolved. There were no clinical or radiographic signs of surgical endodontic management failure at follow-up visits. This case report highlights the clinical significance and surgical endodontic management of infected lateral canal of maxillary incisor. It is important to be aware of root canal anatomy variability in maxillary incisors. Maxillary central incisors infected via the lateral canal can be successfully managed by surgical endodontic treatment.

Root canal treatment of a mandibular second premolar with three separate root canals: Seok-Ryun Lee, Seol-Hee Shin, Sung-Ok Hong, Chang-Kyu Song, Hoon-Sang Chang, Kyung-San Min; J Korean Acad Conserv Dent 2010;35(4):302-305. Published online July 31, 2010; DOI: https://doi.org/10.5395/JKACD.2010.35.4.302

Abstract PDF PubReader ePub

Mandibular premolars show a wide variety of root canal anatomy. Especially, the occurrence of three canals with three separate foramina in mandibular second premolars is very rare. This case report describes the root canal treatment of an unusual morphological configuration of the root canal system and supplements previous reports of the existence of such configuration in mandibular second premolar.
