Chewing asymmetry in dogs: Exploring the importance of the fossa masseterica and first molar teeth morphology.

Dogs are animals with strong bite force. This strong bite mechanism has led to significant changes in the skeletal system such as fossa masseterica. It can be thought that one side is used more than the other side in chewing and is related to the preference of using the same side's hand, eye and foot. In the study, directional asymmetry and fluctuating asymmetry, which occurs as a result of chewing asymmetry, were examined on the first molar teeth and the fossa masseterica in 85 dog mandibles including a wide diversity of morphotypes. The association of high PC1 values for directional asymmetry with a pronounced cranial index, as evident in breeds like Pekingese, Pomeranian and Bulldog, indicates a potential evolutionary or selective breeding trend favouring brachycephaly. On the contrary, guardian breeds like the German shepherd and Bernese mountain dog, which typically require strong jaws for their roles, showcased reduced PC1 values, which might be related to their functional morphology. Similarly, the PCA results for the first molar teeth shape variations also highlighted the influence of cranial shape, with boxer dogs displaying notably higher PC1 values. The fluctuating asymmetrical distributions provided valuable insights into individualistic variations. Interestingly, no specific breed distribution trend was observed for these asymmetries, indicating a more individual-based variation rather than breed-based. It is essential to note that while these results provide valuable insights, further studies are required to understand the underlying causes better. Factors like genetic variations, developmental processes, dietary habits and external environmental factors could play pivotal roles in these observed morphological differences.

Endodontic retreatment of a mesotaurodontic mandibular first molar with C-shaped configuration in a patient with multiple taurodonts: A case report and review of literature

Abstract Taurodontism is a dental anomaly characterized by an apical displacement of the pulp chamber floor, resulting in a large pulp chamber with short roots. It can be associated with certain syndromes and abnormalities, although it is common to occur as an isolated characteristic. This anomaly can occur along with other root canal system anomalies such as C-type configuration. The aim of this report is to present the successful endodontic management of a C-shaped mesotaurodontic mandibular molar and review the literature available on this matter. A 23-year-old Persian female was referred by her dental surgeon to complete the root canal treatment of her right mandibular first molar (#46). Clinical examination showed a temporized cavity with no response to pulpoperiapical tests or visible pocket depth while an elongated root trunk with slight periodontal ligament widening, incomplete obturation of the root canal system, and periapical radiolucency was evident on the intraoral radiograph. Cone-beam computed tomography (CBCT) revealed a taurodontic and type III C-shaped root canal configuration. With a diagnosis of previous treatment and asymptomatic apical periodontitis, the patient was scheduled for root canal retreatment. The same anomaly was discovered in other molar teeth on the panoramic radiograph taken before the primary treatment of tooth #46. At a 2-month follow-up session, the tooth was found asymptomatic clinically and radiographically. The past publications about the management of nonsyndromic taurodontic molars were also reviewed. The review of 29 similar articles showed that preoperative CBCT, magnification with illumination, along with active irrigation are helpful items in managing such cases.

Monolithic Zirconia Single Crowns Supported by Narrow- or Standard-Diameter Titanium-Zirconia Implants in Posterior Sites: 1-Year Results of a Randomized Controlled Trial.

To compare the prosthetic outcomes of screw-retained monolithic zirconia (Zr) single crowns supported by either narrow-diameter (3.3 mm) or standard-diameter (4.1 mm) tissue-level titanium-zirconia (TiZr) implants in posterior sites. A total of 18 participants, each with a missing molar or premolar tooth requiring an implantsupported single crown, were randomly assigned to either the test or control group. All participants received screwretained monolithic Zr single crowns supported by single tissue-level TiZr implants. Test group participants received narrow-diameter implants (3.3 mm), whereas control group participants received standard-diameter implants (4.1 mm). A modified version of the United States Public Health Service (USPHS) criteria was used to assess the prosthetic outcome across 12 parameters after 1 year of function. Data were analyzed descriptively, and statistical analysis was performed using a statistical software (SPSS, Version 28.0; IBM) with the level of significance set at P < .05. Of the 18 single crowns delivered, 16 were available for review at the 1-year follow-up, including 7 in the test group and 9 in the control group. Patient characteristics and crown site distribution were similar, with no significant differences observed between the two groups (chi-square test; P < .05). There were no crown failures, meaning a crown survival rate of 100% was achieved after 1 year. The prosthetic outcome based on USPHS criteria was comparable between the two groups with no significant differences observed (chi-square test; P < .05). There were 19 prosthetic events in total (10 in the test group and 9 in the control group), with no significant differences between the groups (chi-square test; P < .05). Loss of proximal contact was the dominant event, with a total of eight events (three in the test group and five in the control group). Patient satisfaction after 1 year was high in both treatment groups, with no significant differences detected. Screw-retained monolithic Zr single crowns supported by either narrow- or standard-diameter tissue-level TiZr implants in posterior sites have comparable prosthetic outcomes after 1 year. Long-term results from well-designed trials are still needed to validate the findings of the present study.

Panoramic Radiography in the Evaluation of the Relationship of Maxillary Molar Teeth and Maxillary Sinuses on the Deep Learning Models Improved with the Findings Obtained by Cone Beam Computed Tomography.

Panoramic radiography (PR) is available to determine the contact relationship between maxillary molar teeth (MMT) and the maxillary sinus floor (MSF). However, as PRs do not provide clear and detailed anatomical information, advanced imaging methods can be used. The aim of this study was to evaluate the diagnostic performance of deep learning (DL) applications that assess the relationship of the MSF to the first maxillary molar teeth (fMMT) and second maxillary molar teeth (sMMT) on PRs with data confirmed by cone beam computed tomography (CBCT). A total of 2162 fMMT and sMMT were included in this retrospective study. The contact relationship of teeth with MSF was compared among DL methods. DL methods, such as GoogLeNet, VGG16, VGG19, DarkNet19, and DarkNet53, were used to evaluate the contact relationship between MMT and MSF, and 85.89% accuracy was achieved by majority voting. In addition, 88.72%, 81.19%, 89.39%, and 83.14% accuracy rates were obtained in right fMMT, right sMMT, left fMMT, and left sMMT, respectively. DL models showed high accuracy values in detecting the relationship of fMMT and sMMT with MSF.

Frequency of Second Mesiobuccal Canal in Permanent Maxillary Molars: An Observational Study

Background: The success of root canal therapy in endodontics is heavily dependent on identifying a second mesiobuccal canal (MB2) in permanent maxillary molars. A comprehensive understanding of internal anatomy, particularly the recognition of MB2, is crucial for the effective treatment of this commonly encountered tooth. This study aimed to investigate the prevalence and occurrence of the second mesiobuccal canal in permanent maxillary first and second molars. Methods: This cross-sectional study that was conducted at the Department of Conservative Dentistry &amp; Endodontics, Military Dental Centre Dhaka, Bangladesh from January 2018 to December 2018. The analysis involved a total of 200 maxillary first molars and 200 maxillary second molars. In the initial phase for both groups, teeth were examined with the naked eye followed by microscopic assessment. Data analysis was conducted with MS Office tools. Results: In naked eye observation, the frequency of MB2 canals in the first molar teeth was found 64%, and in the second molar teeth it was found 56%. On the other hand, by microscopic assessment, the frequency of MB2 canals in the first molar teeth was found 96%, and in the second molar teeth, it was found 84%. Conclusion: The occurrence of the second mesiobuccal canal (MB2) in permanent maxillary first molars is more common than in the second molars. Microscopic assessment proves to be more effective than naked eye assessment for detecting the presence of MB2 in both maxillary first and second molars.

Comparison of the efficacy of tricalcium phosphate and mineralized plasmatic matrix graft for the bone defect in the distal second molar tooth after surgery of the lower impacted third molar tooth

Aim: After the extraction of mandibular horizontal and mesioangular teeth, a defect occurs in the distal part of the second molar. In this study, the effect of MPM on these defects was evaluated. Materials and methods: 36 patients randomly divided into 3 groups. The first group included MPM and PRF. The second group included B-tcp and PRF. In the 3rd group, the extraction socket was left empty. At preoperative and postoperative 6th months, periodontal pocket depth, gingival index and plaque index, and the distance between the enamel junction and crestal bone at the distal of the 2nd molar were measured by CBCT. 8 patients were removed for various reasons. 28 patients were evaluated. Results: Preoperative and postoperative periodontal pocket depths at the sixth month were 7.67 ± 1.58 mm and 4.67 ± 1.23 mm in the MPM group (p&lt;0.001); 6.60±1.96 mm and 4.70±1.34 mm in the β-TCP group (p&lt;0.001); 6.78±1.48 mm and 5.56±1.01 mm in the control group (p&lt;0.023). Bone defects preoperatively and at six months postoperatively were 7.97 ± 1.04 mm and 3.59 ± 0.66 mm in the MPM group (p&lt;0,001); 6.23 ± 1.37 mm and 2.90 ± 1.04 mm in the β-TCP group (p&lt;0.001); 6.92±0.82 mm and 4.30±0.68 mm in the control group (p&lt;0.001). Conclusion: MPM is an effective graft material to restore the periodontal health of the distal part of the second molar after impacted lower third molar surgery

Disappeared Third Molar Tooth: A Case Report

Many complications can be encountered during diagnosis and treatment in healthcare. These can range from the simple to the serious enough to be life-threatening. Preventing complications before they occur is essential. However, they can occur despite all the precautions taken. When they develop, the process needs to be managed properly. Foreign body ingestion and aspiration are among the most important complications in dentistry. While complications can be overcome more easily in cases of ingestion, emergency intervention may be required in cases of aspiration. In both cases, medical doctors and dentists must work in coordination and the process must be managed. In this case report, the diagnosis of a third molar tooth that was ingested during extraction and the subsequent process is shared.

Etiology and Demographic Distribution of Odontogenic Abscesses in the Maxillofacial Area in Patients Over 18 Years of Age: A Five-Year Retrospective Study.

Introduction Despite the constant development of medicine and the increasing accessibility to medical specialists, in the first quarter of the 21st century, odontogenic abscesses remain one of the leading causes of emergency hospitalization in maxillofacial surgery clinics. Because of the serious and lethal complications that this type of suppurative infection can lead to if not treated promptly, there is a need for constant updating of the knowledge of its origin, which is precisely what is addressed in this original article. Materials and methods It reports on a retrospective study conducted over a five-year period (2018-2023), during which 705 patients aged 18 years and older with a confirmed diagnosis of odontogenic soft tissue abscess of the head and neck underwent emergency surgery. Results The average age of the patients studied was 41 years, with the oldest being an 82-year-old woman. The proportion of males in the study population was higher - 54.18%. Young patients (18-44 years) were the most affected, with a total of 364 patients (213 males and 151 females), while the proportion of old people (75 years of age and older) was the lowest, with a total of 15 patients, including seven males and eight females. The first molars of both jaws (16, 26, 36 and 46) were the cause of the suppurative bacterial infection in the highest number among our study patients - 208 out of 705 (29.5%). Central incisors (teeth 11, 21, 31 and 41) were the least frequent direct cause of odontogenic infection, accounting for only 17 cases out of 705 (2.41%). Discussion The most logical reason for the decrease in the number of patients with odontogenic abscesses with increasing age is tooth loss in older individuals. Our study confirmed the knowledge that the first mandibular molars are the most common teeth leading to the formation of purulent exudate in the adjacent mandibular soft tissues. However, in contrast to the well-known fact for the maxilla that canines are the most frequent etiologic factor for the occurrence of odontogenic abscesses, we conclude that again the first molars (teeth 16 and 26) outnumber the other teeth of the maxillary dentition, with canines outnumbering only incisors. The teeth of the lower jaw are the cause of more than twice as many exudative infections as those of the upper jaw - the ratio between them is 2.54:1. Conclusions Knowledge of odontogenic abscesses - their demographic distribution, frequency and etiology, their diagnosis and treatment - is the basis for the prediction and treatment outcome of these diseases, mainly affecting young people. Their treatment is both surgical in order to evacuate the suppurative focus, and antibacterial.

Application of Fractal Analysis in Detecting Trabecular Bone Characteristics Around Mandibular Impacted Third Molars on Dental Panoramic Radiographs

Purpose: Surgical extraction of third molars can be difficult for many reasons, including increased bone density, which causes bone structures to lose their elastic properties. The aim of this study is to compare the trabecular structure around the impacted mandibular third molar(M3M) and the normal alveolar trabecular pattern using the fractal analysis method. Materials and Methods: Panoramic images of 47 patients were included in the study. ROI1 is the area between the distal root of the second molar and the mesial of the third molar tooth. On the other hand, ROI2 was selected between the distal root of the first molar tooth and the mesial root of the second molar tooth. Fractal Dimension (FD) and Bone Marrow Dimension analyzes were applied to the selected ROIs using the ImageJ software. Results: The mean FD values of 47 patients were found to be 1.135 for ROI1 and 1.105 for ROI2, respectively (p=0,078).The mean Bone Marrow Dimension values were found to be 1.591 for ROI1 and 1.587 for ROI2(p=0.731). There was no significant difference in FD and Bone Marrow Dimension analysis when ROI1 and ROI2 were compared. It is very important to know the pattern of trabecular structure before surgical procedure on M3M. The bone density around the impacted M3M may be higher than the healthy alveolar bone, however, the fact that males have denser bone than females should not be ignored during the operation. Conclusion: The method of FD analysis can be useful for evaluating the trabecular structure of impacted M3M. Key words: fractal dimension; bone structure; panoramic imaging; impacted tooth; third molars

Novel cryotherapy technique for pulpotomy in mature permanent teeth with symptomatic irreversible pulpitis- a randomized controlled trial.

To assess the effect of cryotherapy on haemostasis, post-operative pain, and the outcome of full pulpotomy performed in mature permanent teeth with symptomatic irreversible pulpitis. The study included sixty mature permanent mandibular molar teeth with symptomatic irreversible pulpitis and no periapical rarefaction. After coronal pulp tissue amputation, teeth were randomly allocated to one of two groups (n = 30 each). In group I (conventional pulpotomy), a sterile cotton pellet moistened with 2.5% NaOCl was used for haemostasis. In group II (cryotherapy), the pulp chamber was continuously lavaged with 2.50C normal saline solution for haemostasis using an indigenous portable cryotherapy irrigation unit. Following haemostasis, the pulp was capped with mineral trioxide aggregate and the tooth was restored with resin composite. The time taken to achieve haemostasis was recorded. Preoperative and 24, 48 and 72h postoperative pain was measured using the Numerical Rating Scale. The pulpotomy outcome was assessed at the 12-month follow-up. Data were analyzed using Fischer's exact test, two-sample t-test, two-sample Wilcoxon rank-sum test, Friedman Test, and Wilcoxon Signed Rank Test. The cryotherapy group achieved haemostasis in less time (p < 0.05). There was a significant pain reduction at 24 and 48h in the cryotherapy group when compared with the conventional pulpotomy group (P < 0.005). The overall success rate of pulpotomy after 12 months was 88% (n = 22) in both study groups(p < 0.05). Cryotherapy application reduces postoperative pain and has no adverse effect on the outcome of pulpotomy in permanent teeth with symptomatic irreversible pulpitis. The cryotherapy can be incorporated in pulpotomy protocol as an adjunct to minimize post-operative pain.

A Combined Endodontic Management Approach in immature Permanent Molar tooth with Periapical Lesion: Case Report

Immature dental pulp, which has a highly cellular structure and a rich vascular nutrition system, is highly resistant to inflammation, In these teeth, determining the treatment option based on clinical and radiographic findings alone may result in the removal of diseased pulp tissue as well as vital pulp tissue. In order to increase the prognosis of these teeth, vital pulp treatments are highly recommended to preserve pulp vitality. By evaluating the condition of the root pulps of young permanent molars separately, it is possible to increase the prognosis of the tooth by combining regenerative endodontic treatment and pulpotomy treatment according to the condition of the pulps. In this case report, regenerative endodontic treatment and pulpotomy treatment were applied to different root canals of the first molar, which became necrotic before completing its maturation due to caries and had an apical lesion, and excellent healing was demonstrated. Key words: Biodentine, immature permanent teeth, periapical lesions, pulpotomy, regenerative endodontic treatment.

Case Report: A rare case of bilateral molar natal teeth in a term newborn

Reports of natal and neonatal teeth have been well documented in the literature, though the presence of natal primary molars remains rare, and a clear management strategy does not exist. This is a case study of a female newborn delivered at a gestational age of 41 weeks 1 day to a 31-year-old G1P1001 mother. Apgar scores were 8 and 9 at 1 and 5 min, respectively. The infant was delivered by cesarean section and was admitted to the Mass General Hospital Newborn Nursery, where she received routine care. The patient had two posterior molars, which warranted consultation for oral maxillofacial surgery. Due to the gross mobility of the natal teeth and the risk of aspiration in a small breastfeeding newborn, the decision was made to extract the natal teeth immediately. Understanding the management of natal teeth is important for the pediatrician.

Open isthmus and lambda (Λ) sign of early Joubert syndrome: elucidating development of molar tooth sign.

A data-driven approach for the partial reconstruction of individual human molar teeth using generative deep learning.

Due to the high prevalence of dental caries, fixed dental restorations are regularly required to restore compromised teeth or replace missing teeth while retaining function and aesthetic appearance. The fabrication of dental restorations, however, remains challenging due to the complexity of the human masticatory system as well as the unique morphology of each individual dentition. Adaptation and reworking are frequently required during the insertion of fixed dental prostheses (FDPs), which increase cost and treatment time. This article proposes a data-driven approach for the partial reconstruction of occlusal surfaces based on a data set that comprises 92 3D mesh files of full dental crown restorations. A Generative Adversarial Network (GAN) is considered for the given task in view of its ability to represent extensive data sets in an unsupervised manner with a wide variety of applications. Having demonstrated good capabilities in terms of image quality and training stability, StyleGAN-2 has been chosen as the main network for generating the occlusal surfaces. A 2D projection method is proposed in order to generate 2D representations of the provided 3D tooth data set for integration with the StyleGAN architecture. The reconstruction capabilities of the trained network are demonstrated by means of 4 common inlay types using a Bayesian Image Reconstruction method. This involves pre-processing the data in order to extract the necessary information of the tooth preparations required for the used method as well as the modification of the initial reconstruction loss. The reconstruction process yields satisfactory visual and quantitative results for all preparations with a root mean square error (RMSE) ranging from 0.02 mm to 0.18 mm. When compared against a clinical procedure for CAD inlay fabrication, the group of dentists preferred the GAN-based restorations for 3 of the total 4 inlay geometries. This article shows the effectiveness of the StyleGAN architecture with a downstream optimization process for the reconstruction of 4 different inlay geometries. The independence of the reconstruction process and the initial training of the GAN enables the application of the method for arbitrary inlay geometries without time-consuming retraining of the GAN.

Biometric analysis of furcation area of molar teeth and its relationship with instrumentation

The anatomy of furcation favours the bacterial retention and makes periodontal debridement as well as oral hygiene procedures difficult. Teeth that have lost attachment to a level of the furcation are said to have a furcal invasion or furcation involved.Involvement of furcation in a multi-rooted tooth poses a very different type of clinical situation in terms of establishment of diagnosis, determination of prognosis and of course planning the treatment modality.The present study was carried out on 200 selected extracted human first and second permanent molar teeth based on a predefined criteria. Teeth with prosthetic crowns, fused or fractured roots, those not fully developed, grossly carious or heavily restored at the cementoenamel junction (CEJ) were excluded from the study. The morphology of the root trunk was recorded by measuring various dimensions of the root trunk,including furcal angle and root trunk volume was calculated by using a custom made special apparatus. The furcation areas were debrided with different types of curettes in the market in order to see how best the instrument could be maneuvered in the furcation area. The data so obtained was statistically analysed using SPSS version 22. The highest root trunk volume and the longest root trunk length were found to be in the maxillary second molar. 48.60% furcations didn’t allow instrument engagementof furcation area with standard area specific curettes. The proposal of inclusion of root trunk length (mm) is suggested in addition to classification of FI to have assess prognosis and appropriate treatment for of the involved tooth.

Assessment of physical properties of bioactive glass-modified universal multimode adhesive and its bonding potential to artificially induced caries affected dentin

BackgroundTo evaluate the physical properties of bioactive glass-modified universal multimode adhesive and its micro-tensile bond strength (µTBS) to artificially induced caries-affected dentin.MethodsAll bond universal adhesive was used in the study. Specimens were divided into 2 main groups: control unmodified adhesive and 5 wt% BAG modified adhesive. The degree of conversion, pH, bioactivity, and viscosity of the adhesives were tested with n = 5 for each test. Micro-tensile bond strength evaluation was done in etch & rinse (ER) and selective-etch (SE) modes, where 24 human molar teeth were used (n = 3), 12 teeth for immediate bond strength, and the other 12 were tested after 6 months of storage in simulated body fluid (SBF).ResultsNo significant difference was found between the control and the 5wt% BAG groups regarding the degree of conversion (61.01 ± 0.43 and 60.44 ± 0.61 respectively) and the viscosity (109.77 ± 22.3 and 124.3 ± 9.92 respectively). The control group revealed significantly lower pH values than the 5wt% BAG group (3.16 ± 0.5 and 4.26 ± 0.09 respectively). Immediate bond strength results revealed that the 5wt% BAG in the ER mode had the highest bond strength followed by the control group in the ER mode (44.16 ± 7.53 and 44.00 ± 7.96 respectively). SE groups showed that the immediate strength of the 5wt% BAG group was higher than the control group (42.09 ± 6.02 and 39.29 ± 6.64 respectively). After 6 months of storage, bond strength results revealed a decrease in bond strength values for the control groups but not for the 5wt% BAG in both application modes.ConclusionsThe incorporation of BAG (5wt%) improved the universal adhesive micro-tensile bond strength and bond durability for both adhesive application modes without affecting its degree of conversion or viscosity.

The Prevalence Of Dental Caries In 1st Permanent Molar Teeth Among Teenage Boys And Girls At FMIC Hospital, Kabul, Afghanistan: An Observational Study

Comparative Evaluation of Success of NeoPutty Mineral Trioxide Aggregate ® with Formocresol as Pulpotomy Medicaments in Primary Molars: A Clinical Study.

This clinical study was aimed to investigate the clinical and radiographic outcomes of NeoPutty MTA ® (Nusmile), a novel mineral trioxide aggregate (MTA) pulpotomy material, in primary teeth of children aged 4-6 years. An in vivo study was done in children aged 4-6 years old. A total of 50 primary second molar teeth were included in the study, with 25 of them undergoing treatment with formocresol (FC) and 25 receiving treatment with NeoPutty MTA ® . The subjects were divided into two groups for treatment: the first group received a treatment involving a 1:5 dilution of Buckley's FC. The second group, however, underwent treatment with NeoPutty MTA ® . This study employs a meticulous approach to evaluate the impact of different treatments on a significant number of molar teeth, using FC and NeoPutty MTA ® as the respective treatment methods. The demographics of the subject pool are well-documented, comprising a balance of male and female participants. The technique employed for pulp removal and the subsequent management of bleeding are outlined, underscoring the thoroughness of the process. At 12 months, the NeoPutty MTA ® pulpotomy group showed a significantly higher success rate clinically (96%) compared to the FC group (72%) ( P < 0.05), but radiographically although NeoPutty MTA ® was better (92%) than FC (82%), it was not statistically significant. NeoPutty ® -treated teeth exhibited no signs of pain or discomfort and demonstrated better pulp vitality compared to the FC group. NeoPutty MTA ® demonstrated superior clinical success rates and better radiographic outcomes compared to traditional FC pulpotomy.

Periorbital emphysema following dental procedure: A case report with literature review

We aimed to present a case of periorbital emphysema after tooth extraction in private dental practice. A 20-year-old female patient with the left maxillary first molar tooth extracted under local anesthesia was referred to the ophthalmologist with complaints of swelling and pain around the left eye 6 hours after the procedure. The best visual acuity was logMAR 0.0 in both eyes on visual examination. In the slit-lamp examination, there was periorbital swelling in the left eye, free eye movement, and a light reaction. The right eye followed naturally. Fundus examination of the bilateral optic nerve was normal. On palpation, crepitation was detected in the left periorbital region. A rapid assessment of airway obstruction was made. Diffuse air was observed in the left orbital soft tissue in orbita computed tomography. Prophylactic penicillin-derived antibiotics and nonsteroidal antibiotics were started. The light reaction was followed closely. Periorbital swelling decreased 24 hours after the procedure. During the surgical removal of impacted teeth, air through the air-operated handpiece may cause spread from the periapical region to the periorbital space along the subperiosteal region and fascial planes. Care should be taken to avoid this rare complication after dental procedures.

Assessment of Two Different Obturation Systems in Primary Teeth: A Comparative Study

ABSTRACT Aim: The purpose of this study was to evaluate the efficacy of two distinct obturation techniques in primary teeth. Materials and Methods: For this investigation, 40 primary molar teeth were taken into consideration. Every sample underwent sample preparation. All teeth were evenly split into two groups: Group 1-obturation using the lentulospiral method and Group 2-obturation using the NaviTip method. The comparison between the two procedures was established through radiographic evaluation of the obturation quality and voids in the obturated canals. Results: In the lentulospiral method, 12 (60%) were optimal filling, 6 (30%) were underfilling, and 2 (10%) were overfilling. In the lentulo spiral method, 40% voids were present, and in the NaviTip method, 15% voids were present. Conclusion: The present study concluded that the NaviTip syringe method was sufficiently effective in regulating voids and yielded the best results for the apical seal, whereas the lentulo spiral approach generated the best results in terms of length of obturation.
