ABSTRACT
Cemento-Ossifying Fibroma (COF) is a rare benign tumor of the jaw characterized by the formation of cementum and bone-like tissue, often arising from the periodontal ligament. This article presents two clinical cases that illustrate the complexities of diagnosing and managing COF. The first case involves a 30-year-old male with a painless, progressively enlarging swelling in the left mandible, diagnosed through panoramic radiography and cone-beam computed tomography (CBCT). Surgical intervention included mandibular resection and reconstruction using an iliac graft. The second case features a 26-year-old female presenting with a non-painful swelling in the right mandibular premolar region, which was also confirmed via imaging studies. Complete surgical resection was performed, and histopathological examination validated the diagnosis of COF. Both cases highlight the importance of accurate diagnostic imaging and histological analysis in confirming COF, as well as the need for individualized surgical approaches based on lesion characteristics. Despite its benign nature, COF can lead to significant morbidity due to local invasion and recurrence potential. The article emphasizes that thorough follow-up is essential to monitor for recurrence after surgical management. These cases contribute to the understanding of COF's clinical presentation and reinforce the necessity for a multidisciplinary approach in managing this condition effectively. Further research is needed to explore the underlying pathogenesis and optimize treatment strategies for COF in clinical practice.

ABSTRACT
Background: This study aims to compare the condylar position in Mexican population with the values of Ikeda Spatial Condyle Analysis with different sagittal skeletal pattern, age and sex using a cone beam computed tomography (CBCT). Objective: To evaluate the condyle-fossa relationship in patients with skeletal patterns and sex using Ikeda Spatial Condyle Analysis assessed with CBCT. Materials and Methods: An observational analytical cross-sectional study, 86 condyles CBCT images were used for this study (August 2023- December 2024). The patients were divided into 3 groups according to 3 criteria: age (12-60 years old with intervals of 5 years); sex (female and male); and skeletal pattern as ANB classification (Class I, Class II, and Class III). Temporomandibular joint space (TMJS): (SAS, sagittal anterior space; SSS, sagittal superior space; SPS, sagittal posterior space; CMS, coronal medial space; CLS, coronal lateral space and CCS, coronal central space) were measured and compared. Statistical analyses were performed using two-sample T test, Mu Test, and Anderson- Darling probability test (p<0.05). Results: The mean age of the participants (n = 43) was 30.9 ± 10.9 years (62.7% female). Differences in condyle-fossa relationships were significantly different between Mexican population and Ikeda Condyle Analysis values (p < 0.05). The mean values showed no statistical differences according to sex or sagittal skeletal pattern. The sagittal measurements showed the mean ratio of SAS (2.1+/- 0.6), SSS and SPS (2.5+/-0.7) and (1.8+/- 0.5), respectively. The coronal measurements showed the mean ratio of CMS (2.3+/- 0.7), CCS and CLS (2.5+/- 0.8) and (2.1+/- 0.6), respectively. Conclusions: The Mexican tridimensional condylar position showed significant differences compared with the Ikeda condylar position. These results can be associated to racial anatomical differences. The condyle-fossa relationship values for skeletal pattern; Left / Right condyles and sex, showed ..

ABSTRACT
Post and core buildups are important for damaged or endodontically stabilized teeth. Zirconia is a common material for these restorations due to its exceptional mechanical properties, biocompatibility, and aesthetic appeal. This study presents a case of a 47-year-old female patient, where the tooth was reconstructed and improved its appearance using zirconia bars and implants and was fabricated using Exocad software exactly as it was done in that process. Although zirconia offers impressive advantages, including durability and natural appearance, it presents challenges such as high cost and possible cracking risks. Studies establish how effective zirconia is at emphasizing the restoration of integrity while acknowledging its limitations.

ABSTRACT
Background: The preschool age is an important period for oral health because all deciduous teeth have erupted. They are vulnerable to dental and oral diseases as they still require assistance and guidance from parents in maintaining oral hygiene. Objectives: To analyze the relationship between the role of parents and the oral hygiene status of preschool children in the agricultural area of Jember, Indonesia. Methods: This is a cross-sectional study among preschool children and their parents in the Jelbuk subdistrict, Jember regency, East Java province, Indonesia. A total of 260 mothers and their children were involved in this study. The sampling method employed was cluster sampling. The parents' role is assessed by filling out a questionnaire sheet and examining oral hygiene status in children using the Debris Index (DI). A Spearman test was performed to find the association of parent roles in the oral hygiene status of preschool children. Results: The role of parents showed that 66.2% of parents were highly involved. The mean of DI was 0.79, which was categorized as moderate. There is a significant correlation between the role of parents and the oral hygiene status of preschool children (p = 0.00). Conclusions: Parents have an important role in maintaining the oral health of preschool children.

ABSTRACT
Aim: This systematic review aims to qualitatively synthesize available evidence on the effect of the smear layer (SL) on the adhesion of bioceramic root canal sealers to dentin. Methods: An advanced literature search was conducted in PubMed and Cochrane, targeting in vitro studies on human teeth published between January 2013 and January 2024, in English. Results: The search yielded 479 articles where 16 studies met the inclusion criteria and were included. Data were collected according to the number of teeth studied, canal preparation, smear layer removal methods, adhesion tests, and sealer types. The review found no consensus on the SL's impact on the adhesion and sealing ability of bioceramic sealers. While MTA-based sealers showed improved adhesion due to the SL's role in forming an interfacial layer, calcium silicate-based sealers either experienced reduced adhesion or were unaffected by the SL. Conclusion: The effect of the smear layer on bioceramic sealer adhesion remains unclear, with variations depending on sealer type, smear layer properties, and irrigants used. For MTA-based sealers, the smear layer plays a significant role in enhancing adhesion. Further research is needed to clarify these interactions.
ABSTRACT
Trauma in the oral mucosa due to orthodontic apparatus can be present at any stage of the treatment and must be considered a latent risk of the latter. Therefore, mucosa must be frequently examined to ensure that the apparatus isn't causing damage that, in some cases, may be irreversible. It is essential for a dentist to recognize oral lesions such as mucocele visually and to bring the proper treatment to the patient. The dentist must inform the patient of the risks present during orthodontic treatment and perform the pertinent and periodic examination of the oral mucosa to avoid unnecessary discomfort to the patient and deflect any distrust that may arise on dental treatment as a whole. This paper reports a case of mucocele in a teen in the late stages of orthodontic treatment and a 15-year-old patient with a previous report of mucocele that had been removed but showed signs of recidivism. Both lesions were treated by surgical removal, and no further recidivism was reported.

ABSTRACT
Background: In dental prosthetics many advances have been achieved, but the great problem is still having with us: that is the resorption of the residual alveolar ridge and managing or preventing the secondary soft tissue changes brought on by bone loss. Objective: To evaluate the rate of resorption of alveolar ridge height of maxillary anterior arch in patients treated with immediate partial denture. Materials and Methods: This observational comparative study was conducted in the Department of Prosthodontics, Bangabandhu Sheikh Mujib Medical University for the duration of one year. On the basis of inclusion criteria patients were initially included in the study. A written informed consent was obtained from every patient. Study sample divided equally into two groups, Group A and Group B. Each group consists of 15 patients. Group A patients were treated with extraction of teeth followed by immediate denture prosthesis and group B patients were treated with extraction of teeth, but not provided by any prosthesis. Data were collected on the basis of alveolar bone resorption in the period of 1 month, 3 months and 6 months of extraction on a predesigned data collection sheet. Results: Mean vertical height at one month follow up was 25.48 (±2.41) mm in group A and 23.43 (±2.85) mm in group B which was statistically significant. Mean vertical height at three month follow up was 23 (±1.33) mm in group A and 22 (±2.99) mm in group B which was statistically significant. Mean vertical height of alveolar bone at six month follow up was 22.5 (±2.71) mm in group A and 21.5 (±3.18) mm in group B which was also statistically significant. Conclusion: Patient treated with immediate partial denture following extraction of teeth shows less alveolar bone resorption than patients treated without immediate partial denture.
