Enterococcus faecalis is a notable pathogen found in the root canals of primary teeth with endodontic infections, often resistant to conventional root canal irrigation solutions, leading to treatment failure. Torch ginger or kecombrang (Etlingera elatior), a spice plant, is reported to contain bioactive compounds with antibacterial properties. This study investigates the antibacterial efficacy of ethanolic extract of torch ginger against Enterococcus faecalis, evaluating its potential as an alternative irrigant based on minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and effective concentration. Samples included Enterococcus faecalis ATCC® 29212™ and 70% ethanol extract of torch ginger, tested in eight concentrations (80%, 75%, 65%, 50%, 25%, 12.5%, 6.25%, and 3.125%) obtained through maceration, alongside two control groups (NaOCl and saline). The Kirby-Bauer disc diffusion method was employed to determine MIC, while the streaking method from MIC testing identified MBC. Data analysis for MIC and MBC values was conducted using the One-Way ANOVA parametric test (p < 0.05). Torch ginger extract demonstrated antibacterial activity against Enterococcus faecalis, with inhibition observed at a minimum concentration of 3.125% with average inhibition zone diameter of 9.63 ± 0.25 mm and reaching up to 80% concentration with average inhibition zone diameter of 15.03 ± 0.21 mm. The MIC was established at 3.125%, and the MBC among the tested concentrations was 80%. The study concludes that the ethanolic extract of torch ginger shows significant antibacterial activity against Enterococcus faecalis. An 80% concentration is identified as the most effective for inhibiting and killing the pathogen, suggesting its potential as an alternative root canal irrigant of primary teeth.

Introduction: Meier-Gorlin syndrome (MGS) has three characteristics: short stature, a small or absent patella, and microtia. Objective: This case report aimed to evaluate orthodontic surgical treatment in a patient with MGS during a 7-year follow-up. Methods: A multidisciplinary approach was performed involving orthodontics and maxillofacial surgery. In the initial phase, orthodontic procedures were performed using rapid expansion of the mid-palatal suture. Orthodontic appliances (Roth prescription) were used and orthodontic decompensation was performed, followed by orthodontic surgery to make aesthetic and functional changes. Results: Surgical orthodontic treatment reduced proclination and protrusion and improved overbite. An adequate correlation of the upper and lower arches was achieved. Aesthetic and functional changes were observed, as well as the opening of the airways. Conclusion: This case report highlights the importance of orthodontic surgical correction to achieve symmetry and functionality, given the facial and physical characteristics present in this syndrome.

A rare form of ectopic teeth is the nasal tooth. This is a very rare clinical phenomenon. A clear etiology was not suspected in most of the reported cases. However, many etiologies have been identified, including maxillary osteomyelitis, dental trauma, nasal infections, development of defects such as cleft palate, and genetic factors. It can cause a variety of problems, like nasal obstruction, chronic rhinorrhea, and voice disturbances. Surgical removal of the tooth has been suggested as a treatment to reduce symptoms and prevent further complications.

An in vitro investigation was conducted to assess the efficacy of Hedstrom and Rotary Retreatment File using Cone Beam Computed Tomography (CBCT) in removing obturating material from moderately to severely curved root canals. Thirty-six removed human molar teeth were split into two groups based on the canal curvature using the Schafer and Schneider method. Each group consisted of 18 teeth. Teeth in Group A had roots that were moderately curved (angles between 10 and 20 degrees), whereas teeth in Group B had roots that were severely curved (angles more than 20 degrees). Following decoronation, each root was ready for obturation using the appropriate rotary files, following the manufacturer’s recommendations. Using the CBCT image, the total surface area of the root canals in the axial cross-section and the volume analysis of the obturated area were calculated. H files were used to retreat half of each group, while Rotary (ProTaper) retreatment files were used for the other half, in accordance with their retreatment protocol. It was noted how long it took to reach the working length and remove all obturating items. Cone beam computed tomography and Auto CAD software are used to analyze the surface area and volume of any residual obturating material in the canal after it has been completely removed. An analysis of the data using the ANOVA test was conducted between four groups. When p < 0.05 was reached, it was deemed statistically significant. Rotary retreatment files were discovered to be the most efficient method for removing obturating material and to take the least amount of time to achieve working length. Compared to the Rotary retreatment file, the H file left greater residue in the root canal. Compared to moderately curved root canal groups, severely curved root canal groups have noticeably more residues. In all four groups, the apical part had more residues than the middle and coronal portions. The obturating substance in the root canal could not be entirely removed using any of the retreatment procedures. Furthermore, there was no advantage in terms of root-filling removal’s effectiveness.
我们进行了一项体外调查，利用锥形束计算机断层扫描（CBCT）评估 Hedstrom 和旋转修整锉在去除中度至严重弯曲根管的钝化材料方面的功效。使用 Schafer 和 Schneider 方法，根据根管弯曲程度将 36 颗拔除的人类臼齿分成两组。每组包括 18 颗牙齿。A 组牙齿的牙根呈中度弯曲（角度在 10 至 20 度之间），而 B 组牙齿的牙根呈严重弯曲（角度超过 20 度）。装饰后，根据制造商的建议，使用适当的旋转锉对每个牙根进行封闭。使用 CBCT 图像计算根管轴向横截面的总表面积和钝化区域的体积分析。根据再治疗方案，每组一半的患者使用 H 型锉进行再治疗，另一半患者使用旋转（ProTaper）再治疗锉。记录达到工作长度和去除所有钝化物所需的时间。锥形束计算机断层扫描和Auto CAD软件用于分析完全去除后残留在牙槽中的钝化材料的表面积和体积。使用方差分析检验对四组数据进行分析。当 P < 0.05 时，即认为具有统计学意义。研究发现，旋转再治疗锉是去除钝化材料最有效的方法，而且达到工作长度所需的时间也最少。与旋转再治疗锉相比，H 型锉在根管内留下的残留物更多。与中度弯曲根管组相比，严重弯曲根管组的残留物明显较多。在所有四组中，根尖部分的残留物都多于中间和冠状部分。任何一种再治疗方法都无法完全清除根管内的钝化物质。此外，在根管充填物去除效果方面也没有优势。

The separation of an endodontic instrument during a root canal procedure is a complication that can significantly hinder successful treatment. Separated instruments blocked access to the apical portion of the root, impeding adequate apical canal debridement and potentially compromising disinfection efficacy, thereby jeopardizing the long-term success of the endodontic therapy. Recent advancements in endodontic technology and methodology have facilitated the management of separated instruments (SIs), potentially enhancing treatment prognosis This article presents a case series of the management of SI using bypassing and braiding techniques. Separated instruments were lodged at various levels in the middle and apical third of the maxillary and mandibular incisor and canine teeth. Today, the majority of broken instruments can potentially be removed safely and effectively. However, instrument removal techniques lead to significant loss of tooth substances, which increases the risk of tooth fracture. The choice of the most appropriate technique for removing the fractured fragment depends on several parameters. The two techniques used in these clinical cases are conservative, simple and less invasive for instrument removal.
根管治疗过程中牙髓治疗器械的分离是一种并发症，会严重阻碍治疗的成功。分离的器械阻碍了根尖部分的进入，妨碍了根尖管的充分清创，并可能影响消毒效果，从而危及根管治疗的长期成功。最近牙髓治疗技术和方法的进步促进了分离器械（SIs）的处理，有可能改善治疗的预后 本文介绍了一组使用旁路和编织技术处理 SI 的病例。分离的器械卡在上颌和下颌切牙和犬齿的中间和根尖三分之一处的不同位置。如今，大多数断裂的器械都可以安全有效地取出。然而，器械取出技术会导致牙齿物质的大量流失，从而增加牙齿折断的风险。选择最合适的技术去除折断的碎片取决于几个参数。在这些临床病例中使用的两种技术是保守、简单和创伤较小的器械去除技术。

This study explores the differences between the distribution of Golden Proportion and Recurring Esthetic Dental (RED) Proportion in natural maxillary anterior teeth. Photographs of the subject’s anterior teeth were taken from the frontal view. The width ratios of canine to lateral incisor and lateral incisor to central incisor were calculated. The existence of the Golden Proportion was considered when the width ratios between canine to lateral incisor or lateral incisor to central incisor were within the range of 0.55–0.66. To evaluate the existence of RED proportion in each subject, the width ratio of canine to lateral incisor was compared with the width ratio of lateral incisor to central incisor. The distribution of the Golden proportion was observed in 66.7% and the RED proportion was observed in 22.2% of the natural dentition of the study population. The existence of the Golden proportion was significantly higher than the existence of the RED proportion in well-aligned natural dentition in the study population (P < 0.05). Clinicians may choose the Golden proportion over the RED proportion during the maxillary anterior esthetic treatment procedure.

Objectives: This study evaluated the stress induced by maxillary denture over mandibular denture and overdentures lined with silicone-based material. Materials and Methods: Three maxillary dentures, a mandibular denture, an overdenture supported by a single implant, and other supported by two implants were made for the following groups: MCD—Mandibular complete denture lined with silicone-based material, OSI—Overdenture lined with silicone-based material supported by single implant, and OTI— Overdenture lined with silicone-based material supported by two implants. The mandibular photoelastic model was axially loaded by the maxillary denture with intensities of 10, 20, or 30 kgf. Photoelastic analysis took place with the maxillary denture in maximum intercuspation with the mandibular prostheses. Results: Photoelastic analysis showed that the 10 kgf load promoted in the mandibular denture greater stress along the photoelastic model mainly in the anterior region. Stress occurred around the single implant with higher intensity at the apex. Stress occurred between the two implants and no stress was shown along the implants and apices. For 20 kgf, stress occurred in the anterior region of the mandible denture; Higher stress is shown around the single implant and apex and smaller at the mandible left side. Stress occurred between the two implants, and few stress at the apex of the left implant. For 30 kgf, stress occurred in the anterior region of the mandible with more intensity on the left side. Stress is shown around and at the implant apex and both mandible frontal sides. Stress is shown between the two implants and little stress at the apex of the left implant. Conclusions: The lined overdentures supported by single or two implants exhibited stress concentration in the implant region compared to lined mandibular denture showing stress along the mandible body. The stress in the overdentures occurred mainly around the single implant or between the two implants. The increase in load intensity had little influence on the increase in stress for the prostheses with lined bases. Clinical Relevance: Intercuspation in the overdenture must have the same importance given to the vertical relationship to relieve the chewing effort in overdenture lined with silicone-based material.

The aim of the quasi-experimental study was to assess and compare anaesthetic efficiency of 4% articaine buccal infiltration (BI) and 2% lignocaine inferior alveolar block (IANB) for pulpal anaesthesia in mandibular first molars. Thirty-nine participants with healthy 1st molar teeth on both sides of the mandible who came for root canal treatment of adjacent teeth were recruited for the trial. All participants received 2% lignocaine IANB on 1st visit and 4% articaine BI on 2nd visit and the appointment was given at least 1 week apart. Pulpal anaesthesia onset and duration were checked by an electric pulp tester. The result showed that 4% of articaine BI secured 53.8% successful pulpal anaesthesia in mandibular first molar teeth while 2% of lignocaine IANB did 61.5%, and this difference was not statistically significant. The onset time of pulpal anaesthesia showed no significant difference between these two methods. But, the duration of pulpal anaesthesia was significantly shorter in articaine BI than in lignocaine IANB. It can be concluded that 4% articaine BI is a safe and effective method for pulpal anaesthesia in mandibular first molar teeth. But it should be used considering its shorter duration.
