Abstract
Aim and objective: This study was conducted to evaluate the effectiveness of green tea mouthwash on the salivary level of Streptococcus mutans in the preschool children.
Case description: In this randomized controlled clinical trial, 40 cooperative children (4–5 years old) were divided into two groups. The study group included 20 children who did the routine tooth brushing 3 times/day, and then green tea extract mouthwash (8 mL/day) 2 times/day for 4 weeks. The control group included other 20 children who did the routine tooth brushing as the study group but did not use any green tea extract mouthwash. The quantitative microbiological laboratory cultivation method of S. mutans was carried out for each child at the baseline, after 2 weeks, and after 4 weeks of the study period.
Results: Statistically, the results showed that there was a statistically significant difference in the mean log S. mutans counts between the study and control groups in both follow-up periods after 2 weeks and after 4 weeks. Also, there were statistically significant mean percentage decreases in log S. mutans counts for the two groups.
Conclusion: The use of green tea mouthwash showed promising results in reducing the cariogenic salivary S. mutans counts.
Clinical significance: Green tea extract mouthwash is a nontoxic and safe, particularly for children. Catechins, the main bioactive ingredient of green tea, show an antibacterial action; thus, it has a promising effect in decreasing the count of salivary S. mutans and in the prevention of dental caries.

Abstract
Aim: To assess primary canine and molar occlusion in children 5 to 6 years of age in Rass city, Qassim region of Saudi Arabia.
Materials and Methods: The study followed a cross-sectional design to include 296 Saudi boys aged 5 to 6 years in Rass city, Qassim region of Saudi Arabia. The sample was selected randomly from Primary schools utilizing a stratified cluster sampling approach. Each participant was assessed for an occlusal relationship for primary molars using the criteria of Baume and for primary canines using the criteria of Foster & Hamilton. The correlation between primary canine and molar relationship was assessed using chi-square test and "p < 0.05" was adopted as statistically significant.
Results: A total of 296 male children were examined. About 57.4% had flush terminal plane, 36.8% mesial step and 5.7% distal step relationship. Class I canine relationship was observed in 80.7 % of cases while 7.77% and 12.16% of children had class II and class III relationship respectively. Flush terminal plane relationship coincided with class I canine in 67.5% of the children examined. Mesial step was associated with class III canine relationship in 83.3% and distal step with class II canine relationship in 47.8% of the cases. The relationship between molar and canine tooth occlusion in primary dentition was highly significant at p < 0.001.
Conclusion: A flush terminal plane relationship in primary molars and class I relationship in primary canines were the most common among 5 to 6 years old Saudi boys.
Abstract
Aim and objective: The present report aims to present a case of delayed eruption
of permanent maxillary central incisors in an 11-year-old
male child due to the presence of two supernumerary teeth in anterior maxilla.
Case description: In this case, clinical and radiographic assessment revealed the
presence of two supernumerary teeth palatal to unerupted
maxillary permanent central incisors. These teeth were removed surgically under local anesthesia and
were diagnosed as supplemental incisor,
and the other appeared like tuberculate with dens invaginatus.
Conclusion: The permanent incisors erupted spontaneously within 6 months
follow-up after extraction of the two supernumerary teeth without
any orthodontic interception.
Keywords: Delayed eruption, Maxillary incisor, Supernumerary teeth.
