Dental Digital Radiography

Background: Dental digital radiography is more practical and requires fewer doses of radiation than conventional radiography. Because ionizing radiation has a biological effect on exposed tissue, concerns regarding its stochastic effect merit greater attention. In a previous study, it was found that biological changes and increases in the micronucleus occurred after conventional panoramic exposure to gingival crevicular fluid (GCF). Purpose: The purpose of this study is to investigate the difference in biological effects after digital panoramic exposure compared with conventional exposure. Methods: Twenty subjects were classified into two groups according to the radiographic technique employed. The techniques consisted of ten subjects undergoing digital panoramic radiograph exposure and ten others being subjected to conventional exposure. GCF calculated in mm3 was collected by applying paper strips to the anterior maxillary labial gingival sulcus for one minute prior to and ten minutes after exposure. A micronucleus was obtained from a gingival smear on the same quadrant ten days after panoramic exposure. Results: There was a significant difference in the number of micronuclei between conventional and digital panoramic radiographs both before and after exposure (p=0.000). In contrast, increased GCF volume was not statistically significant (p=0.506) before or after digital panoramic exposure, while the significant difference of conventional panoramic exposure was p=0.017. Conclusion: Digital panoramic radiograph exposure induced a biological change only in terms of an increase in the number of micronuclei but not in the volume of GCF.

Panoramic radiography is a radiography technique which is commonly used in dentistry. X-ray radiation from panoramic radiography can cause biological damage, such as the increase of gingival crevicular fluid (GCF) volume. One of materials which was known having the ability to decrease the effect of panoramic radiography is β-carotene in mucoadhesive gingival patch form. The application of β-carotene mucoadhesive gingival patch reduce micronucleus increasing in previous study. The aim of this study is to determine the effect of β-carotene mucoadhesive gingival patch application on palatal gingiva of maxillary incisor teeth to the GCF volume of panoramic radiography exposed patients. This study involved 10 subjects (5 females and 5 males). The GCF sample was taken from the labial sulcus of 11, 12 teeth (treatment group) and 21, 22 teeth (control group) of each subject before and after panoramic radiography exposure. β-carotene mucoadhesive gingival patch was applicated on palatal gingiva before panoramic radiography examination. Sample was collected using an absorbent paper which is inserted to the labial gingival sulcus. The GCF on the absorbent papers were marked by adding ninhydrin 2%, then the GCF volume was measured using a sliding caliper. Paired t-test result shows a significant difference between GCF volume in each group before and after panoramic radiography exposure (p<0.05). Independent t-test shows no significant difference between the GCF volume difference in the control and treatment group (p>0.05). The result of this study shows that the application of β-carotene mucoadhesive gingival patch on palatal gingiva of maxillary incisor teeth shows insignificant effect in decreasing the increase of GCF volume in panoramic radiography exposed patients.

Objective: Gnathoschisis is the most common congenital craniofacial abnormality in patients with cleft lip and/or palate (CL and/or P). The panoramic radiograph is one means to establish a diagnosis and treatment plan with two-dimension photograph. The cone-beam computed tomography (CBCT) is one means of supporting the maxillofacial to get a three-dimension photograph. The aim of this study was to determine the difference in the results of the use of panoramic photos and CBCT in evaluation before and after gnathoplasty surgery.Material and Methods: This is an observational descriptive research with cross-sectional study method. All samples that meet the suitable criteria are put in this research. The data gained by collecting status card at medical record installation about photo panoramic application in gnathoschisis patients was then compare to the examination with CBCT.Results: The result performed shows that there is a significant difference between panoramic and CBCT picture. The CBCT provide better evaluation about teeth age and segment position of jaw curve from the cleft size. While the panoramic photo provides a widely covered area to observe facial and teeth bone.Conclusion: The CBCT results are more accurate in evaluating gnathoplasty surgery than panoramic photo; however, exposure to the radiation should be considered.

ObjectivesThis study aims to compare the microbiota of gingival crevicular fluid (GCF) before and after mechanical debridement (MD) with antimicrobial photodynamic therapy (aPDT) and determine the core efficient microbiota in peri-implantitis after treatment.MethodsWe recruited 9 patients (14 implants) treated with MD+aPDT for peri-implantitis at our center from February 1, 2018, to February 1, 2019. GCF was collected using filter paper strip before and after the treatment. The bacterial 16S rRNA was amplified and sequenced using an Illumina MiSeq platform to characterize the GCF. Bioinformatics and statistical analyses were performed using QIIME2 and R.ResultsA total of 4,110,861 high-quality sequences were obtained from GCF samples. Based on the reference database, 1,120 amplicon sequence variants (ASVs) were finally harvested. Principal coordinates analysis indicated significant differences in the bacterial community structure between the 180 days after-treatment group and pre-treatment group. Difference analysis and least discriminant analysis showed that the differences were mainly reflected in non-dominant bacteria between these two groups. The non-dominant genera with significantly different distribution between the 180 days after-treatment group and the pre-treatment group included Lactobacillus, Pedobacter, Bulleidia, Centipeda, Desulfovibrio, Ochrobactrum, Staphylococcus, Microbacterium, Brevundimonas, Desulfobulbus, and Parvimonas. Moreover, a total of 29 predictive functional categories at KEGG level 2 were identified. The significant difference pathways at KEGG level 2 between after-treatment and pre-treatment were concentrated in infectious disease-related pathways.ConclusionsPatients with peri-implantitis have significant changes in the low-abundance bacteria of the GCF before and after MD+aPDT. MD+aPDT may change the composition of GCF microbiota by increasing the abundance of cluster 1 (beneficial) and decreasing that of cluster 4 (harmful), which may decrease metabolic response to infection and thus improve peri-implantitis.

This study evaluated the influence of apical patency, root filling removal technique and cleaning of the apical foramen, concerning the amount of debris extruded during root canal retreatment. Forty mandibular incisors were randomly assigned to 4 groups - GIM (n=10), GIIM (n=10), GIPT (n=10) and GIIPT (n=10), which were named according to leaving (I) or not (II) apical patency during canal preparation and filling removal technique (manual - M or ProTaper system - PT). After filling material removal, each specimen of each group had the apical foramen cleaned by sizes 15, 20 and 25 instruments, generating 12 subgroups: GIM15, GIM20, GIM25, GIIM15, GIIM20, GIIM25, GIPT15, GIPT20, GIPT25, GIIPT15, GIIPT20 and GIIPT25. Extruded filling debris was collected by a Milipore filtration system, an HV-durapore, 0.45 µm pore filter with a 25 mm diameter. The filters were weighed before and after the collection on an analytical scale (10–5 g), and the difference was calculated. The mean weight of extruded filling debris was analyzed statistically by Kruskal-Wallis and Friedman ANOVA tests (α=0.05). The mean values found in the groups (in mg) were: GIM (0.95±0.94), GIIM (0.47±0.62), GIPT (0.30±0.31) and GIIPT (0.32±0.44). There was no statistically significant difference among any of the groups or subgroups (p>0.05). ProTaper provided the smallest amount of extruded filling material, regardless of presence or absence of apical patency, followed by manual technique, without and with apical patency. Additional amounts of debris were collected during cleaning of the apical foramen, regardless of the instrument, presence/absence of patency or root filling removal technique.

Dental healthcare is very important since dental and oral hygiene should be maintained. Statistics showed that more than 80% of children in developed and developing countries suffer from dental disease. This study aimed to see the safety of OHIS (Oral Hygiene Index Simplified) in primary school students who got and did not get little dentist cadre training in Bangli Regency in 2019. The study was done in an experimental design: pre and post-test with control design, which was conducted in August-September 2019. The sample in this study is 366 students. The difference in OHIS scores before and after treatment in the control group and treatment group was carried out by the bivariate Mann Whitney U Test. The results of the study showed that before dental health training was conducted, there were 54.3% of primary school students in the treatment group with good OHIS score criteria, and after the training was carried out as many as 98.4% of the students in the treatment group had a good OHIS. Additionally, prior to the training, 57.5% of the control group had fair OHIS criteria score. Then, after the training was carried out, 73.7% of the control group had good OHIS score. Hence, the study concluded that there was a significant difference in the OHIS of primary school students who got little doctor training prior to and after the training. Also, there was a significant difference in the OHIS of the students who did not get such treatment before and after the training.

The aim of this study was to determine the effect of Moringa oleifera leaf extract supplements, Moringa oleifera leaf extract plus royal jelly and placebo on hemoglobin levels in anemic pregnant women. This research is a randomized controlled double blind design study which was conducted in Polombangkeng Utara District, Takalar Regency for 2 months. The subjects of this study were pregnant women with anemia, the majority of which were 20-35 years old, primigravida parity, income less than UMR, unemployment, higher education, pregnancy distance of more than 2 years with p value> 0.05. Then divided into three groups, namely Moringa capsules plus royal jelly (KRJ) (n = 24), Moringa capsules (KTR) (n = 24) and placeco (PLC) (n = 21). Before and after the intervention, measurements of hemoglobin levels were carried out using the Hemocue tool and interviewing the characteristics of the respondents. The results showed that the average Hb level increased from each group (mean SD): KRJ 10.06 ± 0.75 to 11.42 ± 1.23, P = 0.001, KTR 10.40 ± 0.46 to 11.15 ± 0 , 90 P = 0.001 and PLC 10.43 ± 0.42 becomes 11.14 ± 0.88 P = 0.002. but there was no significant difference from the difference in the average increase in Hb levels in the three groups, but there was a tendency that KRJ was superior to the KTR and PLC groups with an increase of 1.36 gr / dl, KTR 0.75 gr / dl and PLC 0.71 gr / dl. So it can be concluded that KRJ is better than KTR and PLC in increasing Hb levels in anemic pregnant women in Takalar Regency.

Background: Bariatric surgery has resulted in body weight loss, which claimed by surgery removal specific parts of the stomach with enzyme or sleeve gastrectomy. Objectives: The aim of this study is to determine weight loss and endocrine changes by 12-week fundus resection and sleeve gastrectomy in rabbits. Methods: Twenty-one rabbits, weighing 2.5 - 3.5 kg, were divided into three groups (n = 7): sleeve gastrectomy, experimental fundus resection, and sham group. The weight of rabbits and total ghrelin and leptin levels in the plasma before and after surgery were measured in 12 weeks. Statistical analyses were performed using the Kruskal-Walis test for comparison of the means between the groups, and the difference after months in one group was assayed by Friedman test. Results: The results showed sleeve gastrectomy had a significant weight loss after one month when compared to fundus resection and sham-operated controls (P = 0.008). There was no significant difference in the ghrelin levels after these surgeries, but leptin levels decreased significantly after the fundectomy (P = 0.025). Conclusions: Sleeve gastrectomy is more efficient than the fundus resection in weight loss. It could be suggested as a new option in metabolic disorders due to the high level of leptin.

Crevicular Fluid

Background: Gingival crevicular fluid (GCF) is a biological fluid derived from the gingival sulcus and can be elevated in the inflammatory state of periodontal tissue, such as gingivitis. In previous studies, the number of GCF could also increase after panoramic radiographic exposure. Increase in GCF due to panoramic radiography is a sign of cell damage. Objective: To analyze the effects of panoramic radiography on the volume of GCF in wistar rats with gingivitis. Method: This type of research was true experimental with post test only and control group design. The sampling technique used was simple random sampling. A total of 25 wistar rats were classified into two control groups without exposure (state without gingivitis and gingivitis) and three groups treatment of exposure (state of gingivitis with 1 time, 2 times, and 3 times the exposure). GCF sampling using filter paper was carried out 10 minutes after panoramic radiographic exposure. The filter paper was stained by 2% ninhydrin solution, after that the GCF volume was calculated. Results: There was a significant difference in the number of GCF (p<0.05) in the group without gingivitis and exposure compared to all other groups, the gingivitis group without exposure compared to the gingivitis group with 3 times exposure, and the gingivitis group with 1 time exposure compared to the gingivitis group 3 times with exposure. Conclusion: Panoramic radiography can cause an increase in the volume of GCF in wistar rats with gingivitis. Keywords: GCF, gingivitis, panoramic radiography
