Abstract

The acetylation process using acetic anhydride entails substituting a hydroxyl group (OH) on p-aminophenol with an acetyl group (-COCH3), resulting in the synthesis of paracetamol. In addition to acetic anhydride, this reaction necessitates the presence of a catalyst that enhances the reaction rate for improved efficiency. The objective of this work is to demonstrate the process of synthesizing paracetamol through the acetylation of p-aminophenol using acetic anhydride. The literature search was conducted using multiple databases, including PubMed, Web of Sciences, EMBASE, Cochrane Libraries, and Google Scholar, to explore the synthesis of paracetamol through the acetylation of p-aminophenol using acetic anhydride. A sulfuric acid catalyst is often used to mix p-aminophenol with acetic anhydride in the process of making paracetamol. This approach is commonly employed in the synthesis of paracetamol. Colorimetric analysis, employing FeCl3 solution, is a widely utilized method in analytical chemistry for the identification of specific compounds. This approach relies on the observation and interpretation of color changes that occur during the reaction. The Rf value of 0.88, which is identical to that of pure paracetamol, confirms that the combination of p-aminophenol and acetic anhydride produces the most effective acetylation process with a yield of 59.5% and a high level of purity. The resulting product exhibits a melting point range of 169–170°C and an infrared spectrum that is indistinguishable from that of pure paracetamol.

Abstract

Introduction: Early caries lesions are increasingly prevalent, demanding minimally invasive treatment modalities. This study compared the efficacy of resin infiltration and conventional methods in managing early caries lesions in Surabaya, Indonesia. Methods: A randomized controlled clinical trial was conducted involving 120 patients with early caries lesions. Participants were randomly assigned to three groups: resin infiltration, microabrasion, and fluoride varnish application. Lesion characteristics were assessed at baseline, 6, 12, and 24 months using ICDAS criteria and DIAGNOdent readings. Results: Resin infiltration demonstrated significantly higher success rates in arresting lesion progression compared to microabrasion and fluoride varnish at all follow-up periods (p<0.05). Lesion depth and DIAGNOdent values decreased significantly in all groups, with the most significant reduction observed in the resin infiltration group. Conclusion: Resin infiltration proved to be a superior minimally invasive technique for managing early caries lesions compared to conventional methods. Its ability to effectively arrest lesion progression and improve aesthetics highlights its potential as a valuable treatment option in contemporary clinical practice.
The Detrimental Effects of Oral Bad Habits on Children's Oral Health and Dental Development Irawan, Aulia; Marsyama’ah

Abstract

Oral bad habits refer to external sources, such as nail biting, item biting (e.g., pencils and pens), finger sucking, cheek sucking, and mouth breathing. The act of inhaling and exhaling through the mouth is the predominant behavior that frequently leads to irregularities in the facial composition and misalignment of the teeth. Mouth breathing during the growth and development phase can impact dentocraniofacial growth. Persistent mouth breathing results in muscular anomalies in the vicinity of the mouth, perhaps resulting in malocclusion. The purpose of this review is to delineate detrimental oral behaviors in children and elucidate their repercussions on oral health and dental development.

Abstract

Introduction: Dental anxiety is a common problem among children, and it can have a significant impact on their oral health-related quality of life (OHRQoL). This longitudinal study aimed to investigate the impact of dental anxiety on OHRQoL in children in Jakarta, Indonesia. Methods: A cohort of 200 children aged 6-12 years was recruited from six elementary schools in Jakarta. Dental anxiety was assessed using the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) at baseline, 6 months, and 12 months. OHRQoL was measured using the Child Perceptions Questionnaire (CPQ11-14) at the same time points. Sociodemographic data and oral health status were also collected. Linear mixed models were used to assess the association between dental anxiety and OHRQoL over time, adjusting for potential confounders. Results: Dental anxiety was significantly associated with lower OHRQoL scores at all time points. Children with higher dental anxiety scores reported more problems with oral symptoms, functional limitations, emotional well-being, and social well-being. This association persisted even after adjusting for age, gender, socioeconomic status, and oral health status. Conclusion: Dental anxiety has a significant negative impact on OHRQoL in children. Early identification and management of dental anxiety are crucial to improve children's oral health and overall well-being.

Abstract

Introduction: Endodontically treated teeth are more susceptible to fracture due to the loss of tooth structure and moisture. Full-coverage crowns are often used to restore these teeth and enhance their fracture resistance. However, the influence of different preparation designs on the fracture resistance of endodontically treated teeth remains a topic of investigation. This study aimed to evaluate the fracture resistance of endodontically treated teeth restored with full-coverage crowns with different preparation designs in Jakarta, Indonesia. Methods: Forty extracted human premolars were endodontically treated and divided into four groups (n=10): Group 1: Butt-joint margin with a 1 mm chamfer finish line; Group 2: Shoulder margin with a 1.5 mm chamfer finish line; Group 3: Deep chamfer margin with a 2 mm chamfer finish line; and Group 4: Shoulder margin with a rounded shoulder finish line. All teeth were prepared for full-coverage crowns and restored with standardized metal-ceramic crowns. A universal testing machine was used to apply compressive load to the teeth until fracture. The fracture resistance values were recorded in Newtons (N) and analyzed using one-way ANOVA and Tukey's post-hoc test (α=0.05). Results: The mean fracture resistance values (N) were as follows: Group 1 (1250 ± 150), Group 2 (1480 ± 180), Group 3 (1180 ± 130), and Group 4 (1550 ± 200). One-way ANOVA revealed significant differences in fracture resistance among the groups (p<0.05). Tukey's post-hoc test indicated that Group 4 exhibited significantly higher fracture resistance than Group 1 and Group 3 (p<0.05). Group 2 also demonstrated significantly higher fracture resistance than Group 3 (p<0.05). Conclusion: Within the limitations of this study, the shoulder margin with a rounded shoulder finish line provided the highest fracture resistance for endodontically treated teeth restored with full-coverage crowns. The butt-joint margin and deep chamfer margin preparations exhibited lower fracture resistance.
