Abstract Background The aim of this paper was to systematically review the root canal configuration (RCC) and morphology literature of the mandibular second premolar (Mn2P). Methods Systematic research of five electronic databases was performed to identify published literature concerning the root canal configuration (RCC) of the Mn2P up through July 2020. Studies were selected according to predefined search terms and keywords inclusion criteria: “root canal configuration”, “root canal system”, “root canal morphology”, “mandibular second premolar”, “mandibular premolars”, “morphology” and “anatomy”. Further possible studies were identified by cross-referencing and screening the bibliographies of the selected articles. Results From 1622 retrieved studies, 44 studies investigating the internal morphology of 17,839 Mn2Ps were included. Most examined Mn2Ps were single-rooted (89.5–100%); two-rooted (0.1–8%) and three-rooted (0.1–3.5%) Mn2Ps at lower frequency. Most frequent RCCs reported were 1–1–1/1 (55.3–99.6%) followed by 1–1–2/2 (0.5–57%) and 2–2–2/2 (0.6–18%). The meta-analysis of seven studies demonstrated that a significantly higher number of RCC type 1–2–1/1 (OR [95%CI] = 2.05 [1.27, 3.33]) and 2–2–2/2 (OR [95%CI] = 2.32 [0.65, 8.63]) were observed in male than in female patients. Conclusions Different RCC research methods have been reported. Whereas clearing and radiographs were commonly used in the past, CBCT has been prevalent in recent years. A globally high frequency of a 1–1–1/1 RCC in the Mn2P has been reported. Nevertheless, the probability that different, more complicated RCCs can appear in Mn2Ps should not be underestimated and, thus, should be taken into consideration when making decisions during an endodontic treatment.

This study aimed to investigate variations in the root canal morphology of maxillary second premolar (MSP) teeth using microcomputed tomography (micro-CT). Sixty (N = 60) human extracted MSPs were collected and prepared for micro-CT scanning. The duration for scanning a single sample ranged between 30 and 40 min and a three-dimensional (3-D) image was obtained for all the MSPs. The images were evaluated by a single observer who recorded the canal morphology type, number of roots, canal orifices, apical foramina(s), apical delta(s), and accessory canals. The root canal configuration was categorized in agreement with Vertucci’s classification, and any configuration not in agreement with Vertucci’s classification was reported as an “additional canal configuration”. Descriptive statistics (such as mean percentages) were calculated using SPSS software. The most common types agreeing with Vertucci’s classification (in order of highest to lowest incidence) were types I, III, V, VII, II, and VI. The teeth also exhibited four additional configurations that were different from Vertucci’s classification: types 2-3, 1-2-3, 2-1-2-1, and 1-2-1-3. A single root was found in 96.7% and the majority of the samples demonstrated two canals (73.3%). Further, 80% of the teeth showed one canal orifice. The number of apical foramina’s in the teeth was variable, with 56.7% having solitary apical foramen. The accessory canal was found in 33.3%, and apical delta was found in only 20% of the samples. Variable morphology of the MSPs was detected in our study. The canal configuration most prevalent was type 1; however, the results also revealed some additional canal types.

The complex root canal system of maxillary second premolars shows variations among different populations. The aim of this study was to evaluate the root canal morphology of second maxillary premolars in the romanian population. The number of roots, root canals and the root canal configuration were investigated using radiographs in both buccal-oral and mesio-distal incidence. They were categorized using Weine’s classifi cation. Among the 480 teeth, 90.83% had one root and 66.67% one root canal. The frequency of secondary maxillary premolars with two root canals (33.12%) shouldn’t be underestimated. Knowing the variations of the internal root canal morphology of maxillary second premolars in a certain population can lead the clinician to a better approach of the endodontic treatment.

The duration of the study was one year from 1st February 2020 to 1st February 2021.Non purposive sampling technique was used and 200 mandibular first molar were collected. Data collected was analysed using the SPSS Vr 10. Study variables include Number and pattern of the roots in mandibular teeth. Descriptive statistics were used; frequencies of the root canals and their canal pattern were calculated.

The present study was conducted to determine the number of roots and morphology of the root canal system of permanent mandibular first molars (M1) in a Sri Lankan population. Sample of 529 M1 teeth was used. The number of roots was examined and the lengths of the mesial and distal roots were measured to the nearest 0.01 mm. Vacuum injection protocol was used to inject China ink into the root canal system, making it transparent. Root canal morphology was recorded using Vertucci’s classification. Presence of furcation canals, position of lateral canals, intercanal communications, level of bifurcation, and convergence of the root canal system were recorded. M1 showed three roots in 4.1% of the sample. Commonest root canal morphology of the mesial root was type IV and the distal root was type I. The level of bifurcation of the root canals was commonly observed in the cervical one-third of the root while convergence was observed in the apical one-third in both roots. Prevalence of three rooted mandibular first molars is less than 5%. Mesial root showed the most variable canal morphology. Prevalence of furcation canals was 1.5% while that of middle mesial canals was 0.2%.

ABSTRACT Aim To present two cases of rare morphological variations of mandibular teeth which were successfully treated endodontically. Background Variations in root and root canal morphology can be found associated with any tooth with varying degree and incidence. To execute an excellent root canal treatment, the clinician should have thorough knowledge of root canal anatomy. Case report Mandibular premolars and canines usually have a single root and single canal. Occurrences of two roots in such teeth are morphological rarities. Endodontic therapy was performed successfully in these rare cases with the help of preoperative radiographs at different angulations. Conclusion The root canal system is a complex structure that possesses aberrant anatomical and morphological variations. During endodontic therapy, it is always mandatory to follow the guidelines and laws to understand the complexities of the space that has to be cleaned and obturate. Clinical significance Thorough understanding and exploration of the complex root canal system with the help of available diagnostic aids is essential for a successful endodontic therapy.

Introduction: Complexity in root canal morphology leads to chances of failure in endodontic treatment due to missed canal. Availability of Cone-beam Computed Tomography (CBCT) has contributed to assess second mesiobuccal canals in maxillary first molars.Objective: To study the presence of second mesiobuccal (MB2) canals, classify morphology of canals according to Vertucci’s classification and to measure the distance between MB1 and MB2 canals.Materials & Method: 72 CBCT scans including 115 permanent maxillary first molars were evaluated by endodontist and oral radiologist separately using Dicom software to study the mesiobuccal root canal morphology. Oral radiologist and endodontist individually evaluated the scans through coronal, axial and oblique views to study canal configurations. Vertucci’s Classification was used to classify the canal configurations. Statistical tests were done to assess the gender variation and arch side difference.Result: Among 115 images evaluated; 30.4% samples had second mesiobuccal canal. The most common canal configuration was Type I (60.9 %) in mesiobuccal root. The mean distance between MB1 and MB2 canals was 2.39 mm in female and 2.56 mm in male.Conclusion: The occurrence of second canal in mesiobuccal root of maxillary permanent molar is considerable in Nepali patients. CBCT can be an effective tool to detect MB2 canal and other complexities of root canal system to achieve clinical success
