“…This is similar to the Finnish population while another study of Finns showed crown-root ratio of maxillary central incisors between 0.49 and 0.59 in males and 0.52 and 0.66 in females, with males having overall smaller crown-root ratio than females [9] . However, in a study of crown-root ratio in permanent dentition in Saudi Arabia, males had significantly greater crown-root ratio than females in maxillary second premolars, mandibular lateral incisors, mandibular premolars, and mandibular molars [13] .…”

Different types of malocclusion have different craniomaxillofacial morphology and occlusal contact, and the crown-root ratio of teeth is closely related to them. Unhealth crownl-root ratio will affect the long-term stability of teeth. Studies at home and abroad suggest that crown-root ratio has ethnic and gender differences. In orthodontic treatment design, orthodontists should analyze the changes in crown length and crown-root ratio according to the patient's gender, ethnicity and other comprehensive judgments, so as to better estimate the treatment risk, maintain the health of periodontal tissues, and then establish a good occlusal relationship, maintain arch stability, and finally obtain a good treatment effect.

“…Each sample tooth was then decoronated at a level higher than the previously planned root length (15 mm from the root apex) with a sectioning disk (diamond) (KG Sorensen, São Paulo, Brazil) [8]. Since the crown of each sample was in the same vertical plane alteration, the root-tocrown ratio was insignificant in terms of the level of the decoronation radiographically or in vitro [15].…”

Background:Obturation is a crucial step in dentistry, involving the filling and sealing of a prepared root canal with sealer and core material to prevent bacterial invasion and ensure successful treatment. This study employed scanning electron microscopy to compare the effectiveness of 3 obturation techniques -single-cone technique (SCT), cold lateral compaction technique (CLCT), and continuous-wave technique (CWT) -in sealing dentin to recently introduced root canal bioceramic sealer in 30 extracted mandibular second premolars. The goal was to determine the optimal technique for minimizing gaps at the sealer-dentin interface. Material/Methods:Thirty premolars were divided into 3 groups (n=10 each) based on obturation technique: SCT, CLCT, and CWT. All groups used CeraSeal bioceramic root canal sealer. Root samples were sectioned at apical, middle, and coronal thirds, and high-resolution scanning electron microscopy was performed to measure marginal/internal gaps. Data were analyzed using one-way ANOVA and Tukey range test, with P£0.05 considered statistically significant. Results:CWT showed fewer voids at all levels, with non-significant differences within a technique. Among the techniques, SCT had the largest mean gaps at all levels [apical (5.43±0.16), middle (5.28±0.20), coronal (5.73±0.24)], while CWT had the smallest mean gaps [apical (3.02±0.19), middle (2.95±0.14), coronal (2.76±0.15)]. The differences in means between techniques were statistically significant (P£0.05). Conclusions:CWT obturation with CeraSeal root canal sealer produces fewer marginal gaps at the sealer-dentin interface.
