Background: Posterior tooth loss can impact masticatory function, aesthetics, and quality of life. Bridges are a restorative solution, but conventional pontic designs often make it difficult to maintain periodontal hygiene and health. Sanitary pontics offer a design that minimizes tissue contact, facilitates cleaning, and reduces plaque accumulation. Case report: A 23-year-old male patient lost his mandibular right first molar and sought to restore chewing function. After clinical and radiographic examinations, it was decided to restore the edentulous area of tooth 46 using a PFM bridge with a sanitary pontic design. Teeth 45 and 47 underwent abutment preparation, impressions, and fabrication of the bridge. Discussion: The sanitary pontic design has been shown to facilitate oral hygiene, especially under the pontic. The space between the pontic and the alveolar mucosa facilitates effective brushing or flossing, reducing plaque and the risk of gingival inflammation. PFM materials provide appropriate strength and durability for posterior restorations. Conclusion: A Porcelain Fused Metal (PFM) bridge with a sanitary pontic design is an effective restorative alternative for posterior tooth loss, improving hygiene and supporting long-term periodontal health.

Background: Oral health is an important indicator of overall health, well-being, and quality of life.

Data collection took place from May to June 2024, comprising five water samples labeled X, Y, Z, A, and B, obtained from refillable drinking water depots in Patrang District using a simple random sampling approach. The results indicated that out of the five samples tested, the sample labeled Z was positive for Coliform with an MPN value of 920 cfu/mL, while the sample labeled A was positive for both Coliform and Escherichia coli with an MPN value of 2,000 cfu/mL. From these findings, two samples (Z and A) were identified as contaminated, with the highest bacterial concentration found in sample A, which had an MPN value of 2,000 cfu/mL

Recurrent aphthous stomatitis (RAS) is a common inflammatory condition of the oral mucosa characterized by round or oval ulcers with well-defined reddish borders and a shallow base covered by a grayish or yellowish fibrinous pseudomembrane. RAS is generally classified into three clinical types—minor, major, and herpetiform based on the size, number, and duration of the lesions. Several factors contribute to its occurrence, including bacterial infections such as Streptococcus sanguis, immune system dysfunctions, and nutritional deficiencies involving iron, vitamin B12, and folic acid. Other potential triggers include local trauma, hormonal or endocrine imbalances, psychological stress, and allergic reactions. Among these, anemia due to deficiencies in iron, folate, or vitamin B12 is considered an important etiopathogenic factor, although its exact role has not been fully clarified. The management of RAS primarily focuses on symptom relief, promoting faster ulcer healing, and preventing recurrence through both topical and systemic approaches. Effective treatment often includes improving nutritional intake, maintaining oral hygiene, and addressing underlying systemic or psychological conditions. Understanding the multifactorial causes of RAS is crucial in developing comprehensive strategies for prevention and long-term management of this recurrent oral lesion.

Intestinal parasitic infections caused by non-Soil Transmitted Helminths (non-STH), particularly Enterobius vermicularis, remain a public health problem in developing countries, including Indonesia. Transmission does not require soil as a medium but occurs through direct contact, autoinfection, or unclean household environments. In children, infection may cause perianal itching, sleep disturbances, loss of appetite, and secondary infections due to scratching, which can affect nutritional status, sleep quality, and overall growth and development. This study was conducted in Kupang City, an endemic area of helminthiasis, to determine the prevalence and risk factors of E. vermicularis infection among children aged 1–5 years. A cross-sectional design with total sampling was applied to 30 children living in RT 008/RW 003, Penfui Timur Village, Kupang Tengah District, from February to May 2025. Risk factor data were collected using structured questionnaires covering personal hygiene, environmental sanitation, socioeconomic status, and parental education. Infection was identified using the scotch tape technique and microscopic examination. The results showed a prevalence of 7% (2 out of 30 children), mainly among boys aged ≥4 years, with poor personal hygiene, inadequate sanitation, low economic status, and parental education at elementary school level or below. In conclusion, enterobiasis in children is influenced by a combination of behavioral, environmental, and socioeconomic factors. Prevention should not rely solely on mass deworming programs but also require continuous health education for parents, improved hygiene practices, and household sanitation.
