Assessment of the taper angle in porcelain-fused-to-metal crown preparation performed by dental students: Study observational
type: item
description: ABSTRACT Introduction: Indirect restorations, such as fixed porcelain-fused-to-metal (PFM) crown and bridge prostheses, require tooth preparation that follows established principles to achieve restoration success. One of the preparation principles that needs to be considered is the taper angle, resulting from the axial wall tapering. To achieve maximum retention, the recommended taper angle is 6°. In clinical practice, preparation errors are frequently found, such as over-reduction and difficulties in axial tooth reduction. Thus, clinical education is required to improve students’ competence and skills to achieve recommended and more precise preparation results. The aim of this study was to evaluate the taper angle of porcelain-fused-to-metal (PFM) crown preparations performed by dental students. Methods: The study was conducted using a descriptive observational design with a total sample of 30 patients at the Prosthodontics Department at RSGM Unpad treated by clinical students of FKG Unpad. The patients’ jaws were scanned using a digital intraoral scanner, then the size of the taper angles were measured using CorelDRAW, with the ideal taper angle of 6-10°. The collected data were analyzed statistically using the chi-square test. Results: The average taper angle formed mesiodistally and buccolingually was 25,0° ± 14,5° and 14,9° ± 12,7° respectively, both of which were greater than the recommended taper angle. Conclusion: The preparation of porcelain-fused-to-metal performed by FKG Unpad clinical students did not reach the ideal taper angle. Dental students should receive hands-on clinical training to evaluate their tooth preparation performance and outcomes, in order to achieve high quality dental care for patients, using either conventional methods (extracted teeth) or digital methods (dental simulators, augmented reality).

Correlation between dental radiology knowledge and the ability to interpret panoramic radiographs among dental students: Study cross-sectional
type: item
description: ABSTRACT Introduction: Knowledge is the result of human curiosity, and in dental education, students are required to understand the fundamentals of dental radiology. Panoramic radiography, as one of the most frequently used imaging modalities, plays an important role in supporting diagnosis; however, a limited understanding of basic dental radiology concepts often complicates the interpretation process. This study aimed to analyze the correlation between the level of dental radiology knowledge and the ability to interpret panoramic radiographs among preclinical dental students. Methods: This study employed a cross-sectional design using a questionnaire. A total sampling technique was applied, involving 146 students from the Faculty of Dentistry, Universitas Mulawarman. Bivariate analysis was conducted using Spearman’s rho correlation test. The variables assessed were dental radiology knowledge and panoramic radiograph interpretation ability. Results: The findings indicated that 49.3% of students had good dental radiology knowledge, 41.8% had good ability in interpreting panoramic radiographs, and 39.0% were good in both variables. Correlation analysis showed a statistically significant correlation between dental radiology knowledge and the interpretation of panoramic radiographs (Sig. [2-tailed] = 0.001). Conclusions: There is a significant correlation between dental radiology knowledge and the ability to interpret panoramic radiographs among dental students at Universitas Mulawarman.

Oral health care value in disadvantage areas of south lampung regency, lampung province: Study Observational
type: item
description: ABSTRACT Introduction: Dental and oral health is one of the parts that must be kept clean, because through these tissues various microorganisms can enter. Oral health care plays an important role in maintaining a person's well-being and quality of life. In some underdeveloped areas such as South Lampung Regency, Lampung Province, efforts to maintain oral health are still a serious problem for the region, so it is necessary to know the value of maintaining oral health in the community. Methods: This research is a descriptive study using a questionnaire survey method. The sampling technique of this study used a simple random sampling method, with a total of 97 adult respondents who had settled in South Lampung Regency, Lampung Province and were willing to be research subjects. This research instrument is a questionnaire with a total of 41 questions that have passed the validity and reliability tests. Results: The value of oral health maintenance in the good category was 47.3%, the community was in the good category in the dimension of oral health maintenance actions as much as 50.5% and the statement of distance from oral health services which stated that it was close was 10.3%. The low dimensions of the oral health maintenance value variable are due to factors of education level and socio-economic conditions and which play a role in the community of disadvantaged areas of South Lampung Regency, Lampung Province regarding the importance of oral health maintenance, as well as the absence of affordable and easily accessible health facilities for the community.

The relationship between religiosity and oral health status as well as oral health-related quality of life (OHRQoL): Scoping review
type: item
description: ABSTRACT Introduction: The World Health Organization (WHO) reported in 2022 that approximately 3.5 billion people worldwide suffer from oral diseases. Poor oral health not only leads to clinical problems but also results in social disadvantages and reduced quality of life. In health epidemiology, religion is considered a social determinant of health. Higher levels of religiosity are believed to contribute to better oral health through social support and psychological well-being. Religiosity functions as a psychosocial determinant of health that enhances emotional stability and preventive behaviors. Therefore, examining the relationship between religiosity and oral health status, as well as oral health-related quality of life (OHRQoL), is important as a basis for developing promotive and preventive interventions based on a bio-psycho-social-spiritual approach. Methods: A literature search was conducted in PubMed, ScienceDirect, EBSCOhost, and SpringerLink using the keywords “belief,” “religion,” “religiosity,” “oral health,” “quality of life,” and “oral health-related quality of life”. Manual searching was performed through the reference lists of relevant articles. This study employed a scoping review method based on the framework proposed by Arksey and O’Malley. Results: Five publications met the inclusion criteria. Three studies demonstrated a positive relationship between religiosity and OHRQoL, indicating better oral health status and lower mean DMFT scores. Two other studies reported negative associations: individuals without religious affiliation had better OHRQoL, and the prevalence of dental diseases among clergy and monastic communities was higher than that of the local population. Conclusion: Religiosity is associated with oral health status and OHRQoL, acting both as a protective and a risk factor. These findings emphasize the importance of considering spiritual aspects in planning community oral health programs. Practical implications include the integrat…

The success rate of dental implant placement using sinus lift vertical approach technique without bone grafting: Scoping review
type: item
description: ABSTRACT Introduction: Dental implants are a treatment aimed at restoring the function and aesthetics of teeth in the oral cavity. They must have stable integrity in the local bone where they are placed. Sinus lift vertical approach without bone graft is a procedure that can be used to place dental implants in cases of maxillary atrophy. The objective is to map the available evidence regarding the success of dental implant placement using the sinus lift vertical approach without bone graft. Methods: This study was conducted using a scoping review method in accordance with PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analytic for Scoping Review) based on predetermined inclusion and exclusion criteria. Articles were obtained from three databases, namely PubMed, Scopus, and Cochrane focusing on randomized controlled/clinical trial (RCT) study designs published between 2014 and 2023. The analyzed data included the year of publication, study design, number of patients, patient characteristics, implant length, follow-up duration, lifting technique, outcome measurement method, implant survival rate, bone height gain, other success indicators, and complications. Results: Nine articles were included in the review (six two-group RCTs and three three-group RCTs). The results showed a high implant survival rate, ranging from 94.1%-100% and bone height gain up to 4.1 ± 1.0 mm. Reported complications included mucositis and perforation of the mucous membrane. Conclusion: The sinus lift vertical approach without bone graft can be a valid technique and provides good results for dental implant placement in atrophic maxillary conditions requiring bone height gain of less than 4 mm.

The correlation between maternal education level and dental caries status among primary school students in West Jakarta:Study observational
type: item
description: ABSTRACT Introduction: Oral health remains a public health concern in Indonesia, with dental caries being the most prevalent condition. The 2018 Basic Health Research (Riskesdas) reported high caries prevalence among school-aged children, reaching 92.6% in children aged 5–9 years and 73.4% in those aged 10–14 years. The role of parents, particularly mothers, is crucial in shaping children’s oral hygiene habits. Maternal education level may influence oral health knowledge and practices, as mothers with higher education levels generally provide better care for their children’s teeth. Objective: To analyze the correlation between maternal education level and dental caries status among 4th–6th grade students at SDN Tomang 01, West Jakarta. Methods: This analytical observational study employed a cross-sectional design involving 123 students. Data on maternal education level were collected via questionnaires, and children’s dental caries status was assessed using the DMF-T and def-t indices. Spearman’s correlation analysis was performed using SPSS v30. Results: Spearman correlation analysis revealed a significant negative correlation between maternal education level and children’s dental caries status (p < 0.05). The strength of the correlation ranged from moderate to weak, with the DMF-T index showing a moderate negative correlation (r = –0.449) and the def-t index showing a weak negative correlation (r = –0.258). Conclusion: There is a significant negative correlation, ranging from moderate to weak, between maternal education level and dental caries status in school-aged children. Higher maternal education levels are associated with lower dental caries in children.

Formulation and evaluation of a mouth spray preparation using lemongrass (Cymbopogon citratus) essential oil: Study experimental
type: item
description: ABSTRACT Introduction: Gingivitis is an inflammation of the gingival tissue commonly caused by the accumulation of bacterial plaque and remains a major oral health problem with a high prevalence. Long-term use of synthetic antiseptics such as chlorhexidine may cause adverse effects; therefore, safer natural alternatives are needed. Lemongrass (Cymbopogon citratus) essential oil possesses antibacterial and anti-inflammatory activities that support its development as an active ingredient in oral care preparations. This study aimed to formulate and evaluate the physicochemical quality and stability of a mouth spray preparation containing lemongrass (Cymbopogon citratus) essential oil as a potential alternative for the management of gingivitis. Methods: This study was an experimental laboratory study with a descriptive design. Lemongrass essential oil mouth spray preparations were formulated at two concentrations, 0.25% and 0.5%. The evaluation focused on the quality of the preparation, including organoleptic testing, pH measurement, viscosity testing, hedonic testing, and stability testing over four weeks of storage at room temperature (25 ± 2°C). Results: Both formulations were liquid and homogeneous. The 0.25% formulation had a pH below the ideal oral pH range (6–7), whereas the 0.5% formulation met the oral pH range. The viscosity values of both formulations were close to that of water (±1 cP). Organoleptically, the 0.25% formulation exhibited a clearer appearance and milder aroma, while the 0.5% formulation was more preferred by panelists in terms of taste. Both preparations showed good stability over four weeks of storage without significant physical changes. Conclusion: Lemongrass essential oil mouth spray preparations met the quality parameters and remained stable during storage. The 0.5% formulation represents the optimal formulation and may be considered for further development as a preparation for the management of gingivitis. KEY WORDS: gingivitis, mouth spr…

The relationship between blood type and the incidence of caries influenced by saliva ph in dental students: Study cross-sectional
type: item
description: ABSTRACT Introduction: Caries is a chronic disease of the oral cavity characterized by demineralization of dental tissue and damage to the organic components of teeth, resulting in tooth decay. Environmental factors such as dental plaque, diet, and oral hygiene are considered the main etiological factors, so most studies focus on these factors. However, genetic factors such as blood type are thought to play a role in an individual's susceptibility to dental caries. This study aims to determine the relationship between blood type and the incidence of caries influenced by saliva pH Methods: This quantitative study used an analytical survey approach with a cross-sectional design. The research was conducted at Baiturrahmah University, Padang, from November to December 2025, involving 160 participants selected through purposive sampling. Data were collected from blood type records and clinical examinations of dental caries and salivary pH. Univariate analysis was presented in the form of frequency and percentage distributions, while bivariate analysis used the chi-square test and logistic regression. Data processing was performed using the IBM SPSS version 26.0 software. Results: Blood type B has the highest percentage of DMF-T seen from the very high category (17.9%) compared to other blood types. In addition, blood type O has the highest percentage of neutral salivary pH (95.3%). Conclusion: There is a relationship between blood type and saliva pH, there is a relationship between blood type and the incidence of caries, and the most influential factor on the incidence of caries in dental students at Baiturrahmah University is saliva pH.

Antibacterial activity test of nipah leaf extract in inhibiting the growth of streptococcus sanguinis ATCC 10556 on the surface of heat-polymerized acrylic resin: Study experimental
type: item
description: ABSTRACT Introduction: Heat-polymerized acrylic resin denture bases are susceptible to increased Streptococcus sanguinis counts, which can lead to oral health problems. Sodium hypochlorite, commonly used as a denture cleanser, has the potential to damage the physical properties of acrylic resin. Therefore, natural alternatives are needed as a substitute for denture cleaners such as nipah leaf extract (Nypa fruticans wurmb) which has antibacterial bioactive compounds. This study analyzes the antibacterial activity of nipa palm leaf extract in inhibiting the growth of Streptococcus sanguinis ATCC 10556 on the surface of heat-polymerized acrylic resin. Methods: The study used a laboratory experiment, with a post-test only control group design where acrylic resin plates measuring 10 × 10 × 1 mm, which were divided into five treatment groups inoculated with Streptococcus sanguinis were treated with nipah leaf extract with concentrations of 10%, 15%, 20%, and a control group. Then, bacterial growth was calculated and analyzed using the Least Significant Difference test with a sig value p<0.05. Results: Nipah leaf extract has been proven to inhibit the growth of Streptococcus sanguinis. A concentration of 10% showed a lower colony count compared to concentrations of 15% and 20%, so under the conditions of this study, a concentration of 10% showed a tendency to provide a better inhibitory effect. Conclusion: Nipah leaf extract inhibits the growth of Streptococcus sanguinis on acrylic resin surfaces. A concentration of 10% showed better inhibitory effect.
