Background: Cleft lip with or without cleft palate (CL/P) is a facial growth ‘disorder that occurs during gestation and has multifactorial causes owing to both genetic and environmental factors. Several factors can increase the likelihood of CL/P, and one of them is family history. Differences in results obtained from studies conducted across several countries concerning family history as a risk factor for CL/P suggest there is no consensus on how the condition is inherited. Purpose: This study aims to review the literature on the role of family history as a risk factor contributing to the incidence of non-syndromic CL/P (NSCL/P). Review: This review discusses the etiology of CL/P and the risk factors influencing the incidence of CL/P. The review also examines the criteria for inheriting multifactorial disorders to calculate the risks involved should there be a recurrence of the condition based on family history. Conclusion: CL/P is a type of multifactorial disorder with unclear etiology. Therefore, it is important to investigate the risk factors stemming from family history (which play an important role) related to the recurrence risk. Additionally, there should be focus on increasing genetic education and offering counselling to parents and pregnant women.

Background: Lactoferrin is known to have a bacteriostatic or bactericidal effect by binding ions in saliva to interfere with the survival of bacteria that need such ions, such as Streptococcus mutants. Lactoferrin is a whey protein and can be found in formula milk. Purpose: This study aimed to analyse lactoferrin levels before and after consuming formula milk and sterilized milk. Methods: This study was conducted on 22 students aged 7–9 years at Public Elementary School (SD Negeri) 060817 using purposive sampling, with 11 students consuming formula milk and 11 students consuming sterilized milk. Saliva was collected by the spitting method before and after consumption on the first and seventh days. Examination of lactoferrin levels was done using the Enzyme-Linked Immunosorbent Assays (ELISA). Differences in lactoferrin levels in each group before treatment on day one and day seven were analysed using the Friedman and analysis of variance (ANOVA) tests. Differences in lactoferrin levels between the formula milk and sterilized milk groups were analysed using the independent sample t-test and the Mann-Whitney test (p<0.05). Results: The average levels of lactoferrin before consuming formula milk was 0.212 ± 0.034 mg/100ml and increased to 0.222 ± 0.036 mg/100ml and 0.315 ± 0.026 mg/100ml. In the sterilized milk group, lactoferrin levels increased from 0.216 ± 0.033 mg/100ml to 0.225 ± 0.032 mg/100ml and 0.235 ± 0.027 mg/100ml. The increase in lactoferrin levels was more significant in the formula milk group on the seventh day (p=0.001, p<0.05). Conclusion: Formula milk, which contains whey protein, has a high potential in increasing lactoferrin levels.

Background: Caries is one of the most common oral diseases that occur among children. Caries and dental trauma in children may cause early tooth loss, also known as premature loss, and result in occlusion abnormalities caused by the dental arch narrowing. A space maintainer is a preventive orthodontic appliance designed to maintain a narrow arch to prevent premature loss. Purpose: This study aims to describe the treatment of a case of space management in a patient with premature loss by using the space maintainer ‘Y model’. Case: An eight-year-old boy was accompanied by his mother, complaining that the lower posterior right tooth had been extracted. The mother was worried that the new tooth would have an overlapping growth. Case Management: The diagnosis was mandibular primary molar loss. The study cast was analysed based on Moyers 2.62 cm, Huckaba 2.24 mm, and curve determination 2.40 mm. The mandibular removable space maintainer treatment was performed on the patient and was followed by nine control visits every week. The outcome was a successful treatment from the use of the space maintainer ‘Y model’. Conclusion: The space maintainer treatment with the Y model in the paediatric patient showed a good result, evidenced by the tube opening of 1.2 mm, showing that the appliance followed lateral jaw growth.

Background: Tooth eruption begins after crown and root formation and may be delayed by gestational diabetes mellitus. Metformin can control blood glucose levels through gluconeogenesis inhibition, and consuming thymoquinone for diabetic treatment will regenerate pancreatic β cells and reduce oxidative stress. Purpose: The objective of this study is to compare the tooth eruption in rats that were born with diabetes and are being treated with either metformin or thymoquinone. Methods: This study used 48 Wistar rats (Rattus norvegicus L.), and the rat sample was divided into four groups, including rats who were born from healthy mothers, rats who were born from untreated diabetic mothers, rats who were born from diabetic mothers that were treated with metformin and rats who were born from diabetic mothers that were treated with thymoquinone. Diabetes was induced by intraperitoneal injection of a single dose of streptozotocin (40 mg/kg BB). Each rat sample was taken with simple random sampling from different mothers, and body weight, blood glucose levels and levels of tooth eruption were recorded. Eruptions of the maxillary right first molar were measured from the cusp of the tooth to the alveolar epithelial lining. Results: Based on the measurements of tooth eruption, it was found that groups A, C and D were closer to mucosa on day 1, 7 and 14 than group B. Based on statistical analysis, there were significant differences (p = 0.03) between group B and groups C and D. Conclusions: Rats born from untreated diabetic mothers have more delays in tooth eruption than those born from diabetic mothers who are treated with metformin and thymoquinone. Thymoquinone has the potential to be an alternative to metformin because it has been shown to be similarly effective.

Background: Bone regeneration studies involving the use of chitosan–hydroxyapatite (Ch-HA) scaffold seeded with human amnion mesenchymal stem cells (hAMSCs) have largely incorporated tissue engineering experiments. However, at the time of writing, the results of such investigations remain unclear. Purpose: The aim of this study was to determine the osteogenic differentiation of the scaffold Ch-HA that is seeded with hAMSCs in the regeneration of calvaria bone defect. Methods: Ch-HA scaffold of 5 mm diameter and 2 mm height was created by lyophilisation and desalination method. hAMSCs were cultured in hypoxia environment (5% oxygen, 10% carbon dioxide, 15% nitrogen) and seeded on the scaffold. Twenty male Wistar rat subjects (8 – 10 weeks, 200 - 250 grams) were randomly divided into two groups: control and hydroxyapatite scaffold (HAS). Defects (similar size to scaffold size) were created in the calvaria bone of the all-group subjects, but a scaffold was subsequently implanted only in the treatment group members. Control group left without treatment. After observation lasting 1 and 8 weeks, the subjects were examined histologically and immunohistochemically. Statistical analysis was done using ANOVA test. Results: Angiogenesis; expression of vascular endothelial growth factor; bone morphogenetic protein; RunX-2; alkaline phosphatase; type-1 collagen; osteocalcin and the area of new trabecular bone were all significantly greater in the HAS group compared to the control group. Conclusion: The three-dimensional Ch-HA scaffold seeded with hypoxic hAMSCs induced bone remodeling in calvaria defect according to the expression of the osteogenic and angiogenic marker.

Background: After tooth extraction, the socket leaves a defect on the alveolar bone. The administration of shell crab-derived hydroxyapatite maintains bone dimensions that are important for achieving successful prosthodontic treatment. Purpose: The aim of the study was to determine the osteogenic properties, such as the number of osteoclasts, osteoblasts and osteocytes, after the application of hydroxyapatite-based shell crab in the post-extraction sockets of Wistar rats. Methods: There were two groups: the control group (K) and the treatment group (T). Wistar rats were randomly divided into control and treatment groups. After tooth extraction, hydroxyapatite gel derived from Portunus pelagicus shells was applied to the tooth sockets of Wistar rats. Observations and calculations of osteoclasts, osteoblasts and osteocytes were carried out on the 14th and 28th days under a light microscope with 400 times magnification. Statistical analysis was performed using one-way ANOVA. Results: There was a significant difference (p<0.05) between the K14 and P14 groups, K28 and P28 groups, K14 and K28 groups, and P14 and P28 groups. The results indicated that there were significant differences between groups of variables. Conclusion: The application of shell crab-derived hydroxyapatite (Portunus pelagicus) was able to decrease the number of osteoclasts and increase the number of osteoblasts and osteocytes.

Background: Candida albicans was found to be dominant in patients with human immunodeficiency virus / acquired immunodeficiency syndrome (HIV/AIDS). The antifungals fluconazole, ketoconazole, and nystatin were used as oral candidiasis therapy for HIV/AIDS, each of which has differing susceptibility in oral candidiasis therapy. Purpose: The present study aimed to evaluate the susceptibility and antifungal resistance to oral C. albicans in HIV/AIDS patients. Methods: The subjects followed the universal precaution principles. Oral Candida species were isolated from the saliva of 98 HIV/AIDS subjects. Identification of Candida species was carried out by the mycobiotic agar of API 20 C Aux system. Susceptibility and resistance antifungal tests on the Candida species were performed using a Fungus ATB Kit. Results: Candida albicans was the most dominant species found from 98 subjects (95%). The rest were other Candida species. There are 41 subjects (42%) with a history of oral candidiasis, and 57 subjects (58%) without. The history of those who used antifungals were: nystatin = 60 subjects (61%), fluconazole = 39 subjects (40%), and ketoconazole = two subjects (2%). These antifungals have a susceptibility above 80% against C. albicans, except the nystatin group (79%) (p>0.05; 0.628), but fluconazole has a strong correlation (r=0.820) to susceptibility, susceptibility-dependent dose, and resistance. Conclusion: Candida albicans was dominant in the saliva of HIV/AIDS patients. This fungus was effectively treated by fluconazole, ketoconazole and nystatin. These antifungals had a high susceptibility at ≤ 8 μg/mL to C. albicans.

Background: Mastication patterns due to malocclusion with unilateral posterior crossbite may permanently change. Purpose: This study aimed to examine the effect of malocclusion with unilateral posterior crossbite of the superficial masseter and anterior temporal muscles on the crossbite and non-crossbite sides during mastication. Methods: Thirty subjects (8 males and 22 females) between the ages of 17 and 30 years who were students of the 2017–2019 Dentistry and Dental Hygiene Study Program, Faculty of Dentistry, UGM and who had at least two posterior teeth with unilateral posterior crossbite were divided into 10 subjects with Angle’s class I, 10 subjects with class II and 10 subjects with class III malocclusions. The amplitude of the superficial masseter and temporal anterior muscles was performed during mastication using surface electromyography (sEMG). The mean difference between the groups of malocclusion on the crossbite and non-crossbite sides of the superficial masseter and temporal anterior was analysed by a two-way analysis of variance (ANOVA). Results: The results indicated a difference in amplitude mean between the malocclusion types on the crossbite sides and non-crossbite sides of the superficial masseter and temporal anterior muscles (p<0.05). This study confirmed there was a decrease in superficial masseter and anterior temporal muscle activity on the crossbite side rather than in the non-crossbite side in Angle’s class I and class II. However, there was an increase in activity of the superficial masseter and anterior temporal muscles on the crossbite side for class III. Conclusion: Malocclusion with unilateral posterior crossbite affects masticatory activity of the superficial masseter and temporal anterior muscles on the crossbite side.

Background: Dental caries is a multifactorial disease indicated by the progressive demineralisation process of dental tissue. It is caused by an imbalance between the remineralisation and demineralisation processes. The focus of caries management is on prevention. Providing materials that can induce remineralisation is one management of caries prevention. Various materials have been or are being researched, such as casein phosphopeptide amorphous calcium phosphate (CPP–ACP), tricalcium phosphate (fTCP), bioactive glass (BAG), and nanotechnologies such as nano-hydroxyapatite (n-HAP) and silver nano fluorine (NSF). Purpose: This study aims to review the development of enamel remineralisation inducing materials as a newer approach in caries prevention. Review: Various ingredients have been shown to increase enamel remineralisation through different mechanisms in preventing the development of carious lesions. Conclusion: CPP–ACP, fTCP, BAG, n-HAP, and NSF can induce enamel remineralisation as caries prevention agents. n-HAP and NSF are the most effective agents to enhance enamel remineralisation to prevent caries.

Background: According to Riset Kesehatan Dasar (Riskesdas) (2013) and the World Health Organisation (WHO), caries is still a global problem and highly prevalent in Indonesia. Caries is mainly caused by Streptococcus mutans with virulence factors known as glucosyltransferase (GTF). The GTF enzyme contribute to the pathogenesis of caries by converting sucrose to fructose and glucan, which are then used in the formation of biofilms and dental plaques. Natural propolis compounds containing flavonoids, terpenoids, saponins and tannins, can inhibit GTF enzyme activity. Purpose: This study aimed to determine an effective concentration of propolis extract for inhibiting the S. mutans GTF enzyme activity. Methods: This study used propolis extract at 14 μg/ mL, 16 μg/m and 1 μg/mL to determine the inhibitory effect on S. mutans GTF enzyme activity. The GTF enzyme were obtained from the supernatant from S. mutans culture centrifugation. The GTF enzyme activity was measured using high-performance liquid chromatography (HPLC) to calculate the fructose level. Results: The mean fructose concentration at 14 μg/mL, 16 μg/mL, and 18μg/mL were 3.31%, 1.56%, and 0.29%, respectively. Conclusion: The most effective concentration of propolis extract for inhibiting the effect of S. mutans GTF enzyme activity is 14 μg/mL.
