Dental anomaly in number, size, and shape might occur during dental bud morphodifferentiation stage. Gemination and fusion are the most common anomalies. Gemination exhibits two joined crowns and usually a single root. This case report presents a geminated maxillary lateral incisor in a 15-year-old female admitted with symptoms of irreversible pulpitis and normal apical tissues. Clinical examination revealed deep palatal caries and the patient had no swelling and fistula. Responses to both percussion and palpation were normal. After root canal treatment, the patient did not present any signs and symptoms.

 Background and purpose: Palate and lip cleft are prevalent congenital deformities in children that have a multi-factorial etiology involving both genetic and environmental factors. The present study assessed the orthodontic-related quality of life in children with palate and lip cleft.
Materials and methods: This descriptive cross-sectional study was conducted in 83 people with palate and lip cleft attending private dental clinics in Sari, Iran. They were selected via convenience sampling. Orthognathic quality of life questionnaire was completed by patients. The validity and reliability of the questionnaire is confirmed. The quality of life of the participants was determined from different dimensions, including social aspects, dental-facial beauty, oral function, and awareness of dental-facial beauty. One-way analysis of variance, t-test, and Pearson's correlation coefficient were used to analyze the data.
Results: The study included 41 girls and 42 boys with mean age of 12.46 years (8-18 years of age). The frequency of cleft lip and palate, cleft lip, and cleft palate were 49.4%, 22.9%, and 27.7%, respectively. The study showed no significant difference between patients with different types of cleft lip and palate in terms of the total score for quality of life and its dimensions (P=0.02). We found no significant relationship between age and dimensions of quality of life (P<0.05). Age was found to be weakly correlated with the scores of the awareness domain (r=0.24, P=0.02).
Conclusion: The quality of life was found to be at an average level in the population studied. The quality of life was not different between patients with cleft lip or palate.

 Cleft lip and palate as one of the most common congenital malformations of the oral cavity is affected by genetic and environmental factors. Subsequent aspiration during feeding, aesthetic, speech, or functional problems, and dental malformations are the main problems of neonates born with cleft lip and palate. The management of neonates with cleft lip and palate has been remarkably improved in recent years. The use of modern surgical techniques and its combination with such methods as presurgical nasoalveolar molding (NAM) is on the rise. The efficacy of preoperative casting in repairing deformed nasal cartilage in neonates with cleft lip and palate has been confirmed based on the literature. Here, we present the case of a 20-day-old neonate with bilateral cleft lip and palate who underwent presurgical nasoalveolar molding to facilitate feeding and recover facial appearance. The bony cleft of maxillary segments in the child was molded and repositioned with a combination of extra-oral elastic and intra-oral appliances. Elastic forces caused backward pressure against the protruding pre-maxilla  and careful use of forces on the cleft segments improved their positions and allowed definitive muscles and lip repair. In this technique, a nasal stent was attached to the intra-oral mouth plate and was designed to improve nasolabial anatomy.

 Background and purpose: Antimicrobial property is one of the important features of sealers, which plays an essential role in limiting microorganisms from the root canal system. This study was conducted to investigate the antimicrobial properties of EndosealMTA, Sure seal root, and AH26 sealers on Enterococcus faecalis bacteria.
Materials and methods: In this study, ceramic sealers Endoseal MTA, suersealroot, and resin sealer AH26 were used. Each of these sealers was placed in wells in the agar medium for 10-15 minutes to spread and then immediately incubated at 35±2°C for 24 hours. Statistical analysis was performed using SPSS (V.22), with the application of Shapiro-Wilk, Kruskal-Wallis, and ANOVA tests.
Results: The highest mean halo of non-growth was related to the Endoseal MTA group. The antimicrobial property of Suresealroot sealer was lower compared to AH26 sealer, but this difference was not statistically significant. (P=0.368). The antimicrobial property of Endoseal MTA sealer was higher compared to AH26 sealer, but this difference was not statistically significant (P=0.368). The antimicrobial properties of Suresealroot sealer were lower compared to Endoseal MTA, but there was no statistically significant difference (P=0.48).
Conclusion: Ceramic sealers Suresealroot, Endo seal MTA and AH26 resin sealer showed antimicrobial properties against Enterococcus faecalis; But the antimicrobial properties of Ceramic Sealers were not different from resin sealer on Enterococcus faecalis
