Background: One crucial function of root canal irrigation is eliminating smear layer, thus increasing apical sealing ability of endodontic sealers. This study was conducted to compare the effect of final irrigation using 17% EDTA, novel silver citrate, and 0.2% chitosan nanoparticles agitated manually, sonically, and ultrasonically on apical sealing ability of bioceramic sealers in the apical third.Method: Forty-five mandibular premolars were prepared and randomly divided into three experimental groups (n=15). Group 1 used 17% EDTA as the final irrigation, group 2 used novel silver citrate, and group 3 used 0.2% nanoparticle chitosan. Each group was divided into three subgroups (n=5), with subgroup A was using manual agitation, subgroup B using sonic, and subgroup C using ultrasonic. All teeth were obturated using single cone and bioceramic sealers. Observations were made using 120x magnification SEM. The sealer's apical sealing ability was measured by comparing cross-sectional area of obturation area with cross-sectional area of preparation area in the apical third.Result: Results of two-way ANOVA showed that there was a significant difference in final irrigation material (p<0.05), but there was no significant difference in technique and interaction of final irrigation material and technique (p>0.05).Conclusion: Irrigation materials affected the apical sealing ability of bioceramic sealers in the apical third, and 0.2% chitosan nanoparticles produced the highest apical sealing ability than other groups. There is no difference in effect of final irrigation technique and the interaction of materials and final irrigation technique on apical sealing ability of bioceramic sealers in the apical third.

Background: Orthodontic treatment failure and unstable treatment results can lead to orthodontic retreatment. Excessive overjet, convexity, and upper and lower lip protrusion are common in Class II malocclusion. When combined with microdontia (smaller-than-average teeth), it presents unique challenges. Purpose: To describe retreatment of Class II, Division 1 malocclusion with microdontia using orthodontic and conservative approaches. Case: A 25-year-old female patient with a skeletal Class II relationship with bimaxillary retrognathism and protrusion of the lower incisors. An intraoral examination showed a Class II molar relationship on the right side, a deep overbite (5.47 mm), a large overjet (5.33 mm), multiple diastemas, and microdontia in tooth 22. Teeth #14, #24, #34, and 44 were extracted during a previous orthodontic treatment. Case management: Orthodontic retreatment was initiated with bracket placement using the edgewise technique. A multiloop archwire was installed to achieve leveling and alignment with a 0.14-inch stainless steel round archwire. Treatment involved bite opening with L loops, mesialization of teeth #11, #21, #12, and #22, retraction of the anterior segment, finishing, and root paralleling. After 22 months of orthodontic treatment, the brackets were debonded, and the patient received direct composite veneer treatment to reshape teeth #12 and #22. Post-retreatment facial evaluation showed a significant improvement in overall facial harmony. Intraoral examination showed Class I molar and canine relationships, good interdigitation, and adequate overbite (2.9 mm) and overjet (3.2 mm). Conclusion: Orthodontic retreatment of a Class II, Division 1 malocclusion with microdontia, when combined with conservative approaches, can significantly improve the patient’s facial profile and stomatognathic function.

Introduction: Functional crown lengthening is one of the most common surgical procedures that facilitating restorative treatment. It was done on teeth with inadequate clinical crowns in the presence of deep and subgingival pathologies. Inadequate clinical crowns defined as tooth with less than 2 mm cervico-incisal of sound. Case Report: The 32 years old female patient complained on broken restoration on upper left anterior tooth since one week ago. He also complained about upper right anterior tooth that turned brown. The tooth had received root canal treatment with direct composite restoration since 3 years ago, but the restoration on tooth 11 and 21 was broken. The remaining crown on tooth 11 and 21 was less than 2 mm. The periapical radiograph examination showed tooth 11 and 21 was non-hermetic obturation. Functional crown lengthening and root canal treatment was performed on teeth 11 and 21, with porcelain crown restoration and fiber post. Conclusion: Functional crown lengthening result affects the quality of post retreatment restoration. The success of functional crown lengthening is marked by no recurrent gingival hyperplasia after functional crown lengthening.

he bond strength between lithium disilicate veneers and tooth structure depends on factors such as curing technique and luting agent. Preheated composite resins have been proposed as alternative luting agents due to their favorable mechanical and polymerization properties. This study aimed to evaluate the effects of conventional, ramp, and pulse light-curing techniques on the shear bond strength of lithium disilicate when preheated microhybrid and nanohybrid composite resins were used as luting agents. Forty-two maxillary premolars were prepared and randomly assigned to six groups (n = 7) based on the combination of luting agent and light-curing technique: IA (microhybrid–conventional), IB (microhybrid–ramp), IC (microhybrid–pulse), IIA (nanohybrid–conventional), IIB (nanohybrid–ramp), and IIC (nanohybrid–pulse). Lithium disilicate veneers were cemented accordingly, and shear bond strength was evaluated. Results from a two-way ANOVA indicated a significant effect of the type of preheated composite resin on the shear bond strength of lithium disilicate (p < 0.05), while no significant effect of light-curing technique was observed (p > 0.05). This study confirmed that preheated microhybrid composite resin produces greater shear bond strength compared to preheated nanohybrid composite resin. Light-curing technique does not significantly affect the shearbond strength of lithium disilicate.

Introduction: Root canal irrigation facilitates debris removal, lubrication, and the dissolution of organic and inorganic tissues while preventing smear layer formation. However, the chelating properties of final irrigants may deplete calcium ions from the dentin, potentially compromising the flexural strength and modulus of elasticity of the root canal walls. This study aims to analyze the effects of various final irrigants and agitation techniques on these mechanical properties of radicular dentin. Methods: Forty-five mandibular premolars were prepared and randomly divided into three groups (n=15). Group 1 was irrigated with 17% EDTA, Group 2 with 0.2% chitosan nanoparticles, and Group 3 with Ultra Clean. Each group was further subdivided into three subgroups (n=5) based on the agitation technique used: manual (A), sonic (B), and ultrasonic (C). Flexural strength and elastic modulus were measured using a Universal Testing Machine (UTM). Results: Two-way ANOVA showed that the type of irrigating solution, agitation technique, and their interaction significantly affected flexural strength and elastic modulus (p<0.05). Post-hoc LSD analysis revealed significant differences among groups for both flexural strength and elastic modulus (p<0.05), with several exceptions in specific comparisons within the EDTA and Ultra Clean groups, as well as between Ultra Clean manual agitation subgroup and the 0.2% chitosan nanoparticle subgroup (p>0.05). Conclusion: The highest flexural strength and elastic modulus values were observed in the group treated with 0.2% chitosan nanoparticles combined with sonic agitation, while the lowest values were found in the 17% EDTA group using manual agitation.Efek jenis bahan irigasi akhir dan teknik irigasi terhadap kekuatan fleksural dan modulus elastisitas dentin saluran akar: studi eksperimental in vitroPendahuluan: Irigasi saluran akar berfungsi membersihkan debris, melumasi saluran, melarutkan jaringan organik dan anorganik, serta mencegah terbentuknya smear layer. Namun, sifat khelasi pada bahan irigasi akhir berpotensi mengikis dinding saluran akar dengan mengikat ion kalsium, yang dapat memengaruhi kekuatan fleksural dan modulus elastisitas dentin. Penelitian ini bertujuan untuk menganalisis pengaruh jenis bahan irigasi akhir dan teknik agitasi terhadap sifat mekanis dentin saluran akar akar. Metode: Empat puluh lima premolar mandibula di preparasi, dibagi menjadi tiga kelompok secara acak masing-masing kelompok terdiri dari 15 sampel. Kelompok 1 di irigasi dengan EDTA, kelompok 2 diirigasi dengan kitosan nanopartikel 0,2% dan kelompok 3 di irigasi dengan Ultra clean. Masing-masing kelompok dibagi lagi menjadi 3 kelompok dan setiap kelompok terdiri 5 sampel. Kelompok A digitasi manual, kelompok B sonik, dan kelompok C ultrasonik. Setelah itu dilakukan uji =kekuatan fleksural dan modulus elastisitas dengan Universal Testing Machine (UTM). Hasil: Uji ANAVA Bahan irigasi akhir, teknik irigasi, dan interaksi keduanya berpengaruh signifikan terhadap kekuatan fleksural dan modulus elastisitas (p<0,05). Hasil Post-Hoc LSD menunjukkan perbedaan signifikan antarkelompok untuk kekuatan fleksural dan modulus elastisitas dentin (p<0,05), dengan beberapa pengecualian pada perbandingan metode tertentu dalam kelompok EDTA 17% dan Ultra Clean, serta antara Ultra Clean manual dan kitosan nanopartikel 0,2% (p>0,05). Simpulan: Nilai kekuatan fleksural dan modulus elastisitas tertinggi pada penggunaan kitosan nanopartikel 0,2% dengan teknik agitasi sonik serta terendah pada penggunaan EDTA 17% dengan teknik agitasi manual.
