Aim: Preterm birth is the most adverse effect of pregnancy, commonly leading to low birth weight. Our study aimed to assess the relationship between maternal periodontal status and adverse pregnancy outcomes by immediate postpartum periodontal examination and diagnosis.
Materials and methods: 125 mothers were divided into four groups based on gestational day (GD) and newborns' birth weight (BW); the mothers with GD ≥ 259 days and BW ≥ 2500 gm (Control), the mothers with GD <259 days and BW ≥ 2500 gm (PT group), the mothers with GD ≥ 259 days and BW <2500 gm (LBW group), and the mothers with GD <259 days and BW <2500 gm (PT-LBW group). The maternal periodontal assessment was carried out within 3 days after delivery.
Results: The bleeding on probing (BOP) of the PT-LBW group was significantly higher than the control (P = 0.027). The correlation test revealed a mild inverse relationship between BOP and BW (R = -0.23, P = 0.044). According to the new 2018 American Academy of Periodontology (AAP) periodontal classification, there was no significant difference between periodontal status within groups.
Conclusion: The present study suggests that BOP, an early sign of gingival inflammation, is involved in adverse pregnancy outcomes.
Clinical significance: This study is the first of its kind to use immediate postpartum periodontal examination and diagnosis by the new 2018 AAP periodontal classification. The findings demonstrate that signs of gingival inflammation may be associated with adverse pregnancy outcomes. How to cite this article: Yanaranci S, Laosrisin N, Sriprasertsuk A, et al.

Aim: This study aimed to explain the potential factors of dental and oral hygiene behavior as a predictor of dental caries status in children with visual impairments.
Materials and methods: The prevalence of dental caries in visually impaired children was investigated through a cross-senal study conducted at a visually impaired special needs elementary school in Jakarta, Indonesia. The study included 25 visually impaired children aged 6-12 years, with dental caries status examined using the decayed, missing, and filled teeth (DMFT)/dmft index according to World Health Organization (WHO) criteria. Data were collected through comprehensive interviews involving the completion of 13 WHO Annex questions.
Results: The result showed that the overall prevalence of dental caries in visually impaired children was 64%, with an average dmft/DMFT of 2.24/0.96. Some of the factors that significantly influence the dental caries status in children with visual impairments aged 6-12 years include visiting the dentist [p = 0.029, 0.05, Pearson's Chi-square, confidence interval (CI) 95%] and the need for care (p = 0.002, 0.05, Pearson's Chi-square, CI 95%).
Conclusion: In conclusion, the majority of visually impaired children have dental caries, which is influenced by factors, such as visiting the dentist and the need for treatment.
Clinical significance: Visiting the dentist regularly and knowing the need for the treatment are the important factors in preventing of dental caries.

Background: The hepatitis B virus (HBV) is a serious occupational hazard for healthcare workers, including dentists. The purpose of this study is to assess dentists' knowledge, attitude, and practice (KAP) with respect to hepatitis B vaccination.
Materials and methods: A cross-sectional survey of a representative sample of dentists (n = 349) from Lebanon was carried out. Participants' knowledge of hepatitis B, attitudes toward vaccination, and immunization habits were assessed using a standardized questionnaire. To examine the data, descriptive statistics were used, and associations between variables were investigated using appropriate statistical tests.
Results: The study found that most participating dentists are HBV-vaccinated. These dentists boast a basic to a significantly substantial understanding of HBV infection prevention strategies, such as immunization, routine preventive measures, and handling equipment. Notwithstanding the generally positive attitudes towards vaccination, a proportion of dentists lacked some HBV prevention practices, specifically with respect to conducting regular follow-ups of anti-HBs titer levels and getting booster vaccination doses when warranted.
Conclusion: This study sheds light on the KAP of hepatitis B immunization among Lebanese dentists. The findings emphasize the significance of focused educational efforts in view of improving awareness and encouraging a more thorough understanding of the benefits of vaccination. The study provides useful data that can be used to influence public health policies as well as activities aimed at increasing hepatitis B vaccination rates among dental professionals in Lebanon.

Aim: This study aims to evaluate the efficacy of calcium phosphate-poly(lactide-co-glycolide) composite graft in the regeneration of intrabony defects in chronic periodontitis patients over a period of 12 months.
Materials and methods: A total of 11 systemically healthy chronic periodontitis patients with 22 graftable sites were treated with calcium phosphate cement (CPC) bone graft (control group) and CPC-poly(lactic-co-glycolic acid)(PLGA) composite (test group) after flap reflection and debridement. Clinical parameters such as probing pocket depth (PPD) and clinical attachment level (CAL) were recorded at baseline and 3, 6, 9, and 12 months. Bone probing depth (BPD) and radiographic parameters such as defect depth (DD), changes in alveolar crest level (ALR), defect depth reduction (DDR), and percentage in defect depth reduction (PDDR) were calculated at baseline, and 6 and 12 months. The data were recorded and statistically analyzed.
Results: On intragroup comparison, there was a significant improvement in all the parameters over a period of 1 year (clinically and radiographically). However, there was no statistically significant difference between the two groups in any of the parameters though there was a slightly higher bone fill noted in the test group.
Conclusion: Even though the CPC-PLGA composite bone graft showed a slight improvement in clinical and radiographic parameters as compared to the CPC graft, it was not statistically significant.
Clinical significance: A major drawback of Calcium Phosphate cements as bone grafts is their poor degradability. The PLGA microspheres degrade to expose macropores and interconnected pores in the graft substrate which in turn would promote the ingrowth of osteoblasts. Also, this composite graft is mouldable, and resorbable and has been shown to snugly fit into the defects making them a suitable scaffold material.

目的:本研究旨在评估磷酸钙-聚(乳酸-聚乙二醇)复合植骨在慢性牙周炎患者骨内缺损再生中的疗效,为期12个月:共有11名全身健康的慢性牙周炎患者,22个可移植部位,在翻瓣反射和清创后,分别接受磷酸钙水泥(CPC)骨移植(对照组)和CPC-聚(乳酸-共聚乙二醇酸)(PLGA)复合材料(试验组)治疗。在基线期和 3、6、9、12 个月时记录探查袋深度(PPD)和临床附着水平(CAL)等临床参数。在基线、6个月和12个月时,计算骨探查深度(BPD)和放射学参数,如缺损深度(DD)、牙槽嵴水平变化(ALR)、缺损深度缩小(DDR)和缺损深度缩小百分比(PDDR)。结果:组内比较:在一年的时间里,所有参数都有显著改善(临床和影像学)。然而,尽管试验组的骨填充率稍高,但两组之间在任何参数上都没有统计学意义上的显著差异:结论:尽管与 CPC 相比,CPC-PLGA 复合骨移植在临床和放射学参数方面略有改善,但在统计学上并不显著:临床意义:磷酸钙水门汀作为骨移植材料的一个主要缺点是降解性差。PLGA 微球降解后会在移植物基质中暴露出大孔和相互连接的小孔,这反过来又会促进成骨细胞的生长。此外,这种复合移植物还具有可塑造性和可吸收性,并能与缺损部位紧密贴合,因此是一种合适的支架材料。本文引用方式Ojha M, Pawar Chandrashekara Rao D, Gowda V. 骨内缺损再生中磷酸钙-聚乳酸-聚乙二醇移植物的临床和放射学评估:随机对照试验。J Contemp Dent Pract 2023;24(12):921-927.

Aim: This study aims to assess the antimicrobial efficacy and impact on color stability of Thymus (T.) vulgaris solution compared to conventional disinfectants on maxillofacial silicones.
Materials and methods: Various solutions were evaluated, including T. vulgaris solutions at 5 and 10%, saline (control), chlorhexidine (4%), and soap water. The substrates were MDX4-4210 silicone elastomers, and the microorganisms tested were Candida (C.) albicans and Staphylococcus (S.) aureus. The viability of microorganisms was determined through an 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) reduction assay, and color stability was measured using a spectrophotometer with X-Rite Europe software. Statistical analysis was performed using the Kruskal-Wallis test, Mann-Whitney Upost hoc test, and Wilcoxon Signed Rank test.
Results: Soap water demonstrated superior disinfectant action against both microorganisms, while T. vulgaris solutions at 5 and 10% exhibited comparable antimicrobial efficacy. Chlorhexidine and 10% T. vulgaris solution showed minimal color changes in the silicone material. In contrast, soap water and the 5% T. vulgaris solution resulted in clinically unacceptable color alterations.
Conclusion: This study underscores the potential of T. vulgaris as an herbal disinfectant for combating microbial biofilms on maxillofacial silicones, particularly at concentrations of 5 and 10%. The importance of maintaining color stability is emphasized, with Chlorhexidine and the 10% T. vulgaris solution demonstrating effective preservation of esthetics. These findings suggest the viability of considering T. vulgaris as an alternative disinfectant in clinical settings for maxillofacial silicone prostheses.
Clinical significance: Maxillofacial silicones are vital in restoring aesthetic features for individuals with facial trauma, congenital deformities, or post-surgical interventions. Yet, biofilm-related infections jeopardize their durability and visual integrity. Clinically, T. vulgaris signifies a potential advance in prosthodontic care, offering valuable insights for improving antimicrobial performance and aesthetic durability in maxillofacial prostheses.

目的:本研究旨在评估百里香(T. vulgaris)溶液与颌面硅胶上的传统消毒剂相比的抗菌效果及其对颜色稳定性的影响:对各种溶液进行了评估,包括浓度为 5%和 10%的百里香溶液、生理盐水(对照组)、洗必泰(4%)和肥皂水。基材为 MDX4-4210 硅树脂弹性体,测试微生物为白色念珠菌和金黄色葡萄球菌。微生物的活力是通过 3-[4,5-二甲基噻唑-2-基]-2,5-二苯基溴化四氮唑(MTT)还原测定法确定的,颜色稳定性则是使用装有 X-Rite Europe 软件的分光光度计测量的。统计分析采用 Kruskal-Wallis 检验、Mann-Whitney U post hoc 检验和 Wilcoxon Signed Rank 检验:结果:肥皂水对两种微生物的消毒效果都很好,而 5%和 10%的 T. vulgaris 溶液的抗菌效果相当。洗必泰和 10% T. vulgaris 溶液对硅胶材料的颜色变化极小。相比之下,肥皂水和 5% 的 T. vulgaris 溶液会导致临床上无法接受的颜色变化:本研究强调了 T. vulgaris 作为中草药消毒剂的潜力,可用于对抗颌面部硅胶上的微生物生物膜,尤其是在浓度为 5% 和 10% 时。氯己定和 10% T. vulgaris 溶液能有效保持美观,强调了保持颜色稳定性的重要性。这些研究结果表明,在颌面部硅树脂假体的临床应用中,可以考虑将 T. vulgaris 作为一种替代消毒剂:颌面部硅胶对面部创伤、先天性畸形或手术后的患者恢复美观至关重要。然而,与生物膜相关的感染会危及其耐用性和视觉完整性。从临床上看,T. vulgaris标志着修复治疗的潜在进步,为提高颌面修复体的抗菌性能和美观耐用性提供了宝贵的见解。如何引用本文:Peter M, Kanathila H, Bembalagi M, et al. 传统和新型百里香提取物草本消毒液对颌面硅胶上致病性生物膜的体外比较评估及其对颜色稳定性的影响。J Contemp Dent Pract 2023;24(12):967-973.

Aim: This study aimed to compare the clinical outcomes of a conventional Erich's arch bar vs a modified screw-retained arch bar in maxillomandibular fixation of mandibular fracture.
Materials and methods: This parallel-arm randomized control trial included patients from the outpatient clinic with single favorable mandibular fractures that are indicated for closed reduction. They were subjected to maxillomandibular fixation using conventional Erich's arch bars in the control group and modified screw-retained arch bars in the study group. The outcome measures included operating time, glove perforations, postoperative pain, oral hygiene, fixation stability, occlusion, and mucosal coverage.
Results: A total of 20 patients (12 males and 8 females) with a 1:1 allocation ratio were included. There was a significant statistical difference regarding operation time and number of glove perforations in favor of group B as p < 0.001, p = 0.007, respectively. There was a significant statistical difference regarding pain after 1 day (p < 0.001), 1 week (p < 0.001) in favor of group B, and at 4 weeks (p = 0.015), and 6 weeks (p = 0.002) in favor of group A. Regarding oral hygiene at 1 week (p = 0.021) and at 6 weeks (p < 0.001), there was a significant statistical difference in favor of group B. Regarding mucosal coverage at 6 weeks, there was a significant statistical difference in favor of group A (p = 0.005).
Conclusion: The modified screw-retained arch bar can be considered an alternative to conventional arch bar as it provided less application time and better operator safety. It also showed better patient satisfaction regarding pain and oral hygiene.
Clinical significance: Maxillomandibular fixation with the conventional technique was modified to screw-retained arch bar which is less time-consuming and provides better patient and operator satisfaction.

Aims: The purpose of this systematic review was to evaluate the cost-effectiveness and acceptance of children and their parents of the Hall technique (HT) for dental rehabilitation in pediatric dentistry.
Background: The approach of the HT is that of minimally invasive treatment of the dental element and is used exclusively on primary molars. Various studies in the literature point to HT as a restorative option well accepted by children and parents and quite predictable, with low retreatment rates and good cost-effectiveness for the management of primary molars with carious lesions. However, no systematic review in the literature has approached randomized clinical trials on these topics to produce a high level of evidence and help establish clinical HT protocols.
Review results: Eight articles were selected for the systematic review. The HT was more cost-effective than procedures using other restorative materials. Regarding acceptance, in terms of esthetics, high percentages of satisfaction were reported for parents and children, with a divergence between studies in the comparison of esthetic preference with atraumatic restorative treatment. However, when considering crown cementation pain, comfort, anxiety, preference, and satisfaction, the HT was generally better evaluated when compared to other restorative materials.
Conclusion: The HT is an excellent restorative option when considering cost-effectiveness and acceptance and is recommended for use in daily clinical practice.
Clinical significance: Results indicate that HT is superior to other restorative materials regarding its acceptance by children and parents in terms of pain, comfort, anxiety, and crown preference and satisfaction. There were also high percentages of satisfaction with esthetics. Hall technique may initially appear expensive for dentists, but its effectiveness over time and the lesser need for consultations and reinventions ensure better cost-benefit than other restorative materials.

Aim: To compare the removal torque loss (RTL) percentage of screw-retained, cement-retained, and combined screw- and cement-retained implant-supported crowns after cyclic loading and measure the impact of cyclic loading on removal torque.
Materials and methods: Thirty-two dental implants (4.0 × 10 mm) in resin blocks and abutments were divided into four groups (n = 8) based on restoration design: combined screw- and cement-retained group (SC), two cement-retained groups: cemented with adhesive resin cement (AR) (Panavia V5) or provisional cement (PR) (RelyX Temp NE), and screw-retained one-piece titanium group (TI). Removal torques were measured in Newton-centimeter (Ncm) before and after 500,000-cycle cyclic loading with forces ranging from 20 to 200 N at 15 Hz. The RTL percentage in each group was calculated. The paired t-test was used to detect the difference between pre-loading (RT1) and post-loading removal torque (RT2) in each group and 1-way ANOVA was used to detect the difference of RTL percentage between groups.
Results: The post-loading removal torques in all groups were significantly lower than their pre-loading removal torques (p < 0.001). The 1-way ANOVA test found no significant difference in the RTL% between the study groups. The PR group exhibited the lower RTL% (30.74 ± 7.3%), followed by the TI (30.78 ± 5.6%), AR (32.12 ± 2.5%), and SC (35.71 ± 5.1%) groups.
Conclusion: Combined screw- and cement-retained restorations exhibited similar RTL compared with other restoration designs, and cyclic loading significantly affected the removal torque.
Clinical significance: Combined screw- and cement-retained restorations can be utilized in single-tooth situations, offering a comparable impact on screw joint stability while providing benefit of retrievability. Cyclic loading significantly influences joint stability, periodic checkup for screw loosening is recommended. How to cite this article: Jongsiri S, Arksornnukit M, Homsiang W, et al.

Aim: This split-mouth randomized trial (RCT) aimed to assess the effect of diode laser on the clinical parameters in patients with periodontitis, compare the results with scaling and root planing (SRP) alone, and assess the implications of diode laser (DL) on plaque bacteria.
Materials and methods: Seventeen periodontitis patients were randomly assigned into two equal groups based on the therapy delivered. Group I (control site) received just SRP at baseline, while group II (test site) received both SRP and DL irradiation. For both groups, the clinical periodontal parameters probing pocket depth (PPD), and clinical attachment level (CAL) were measured at baseline, 30 days, and 90 days. Microbiological amount was also measured at baseline, 30, and 90 days after periodontal treatment. The amounts of Aggregatibacter actinomycetemcomitans (A.a), Prevotella intermedia (Pr. intermedia), and Porphyromonas gingivalis (P. gingivalis) were determined using real-time PCR probing with specific bacterial primers.
Results: In both groups, PPD and CAL showed statistically significant reductions at different time intervals (p < 0.05). No significant difference were observed in CAL values after 1 and 3 months in both test and control groups (p > 0.05). The mean values of the concentration of A.a, Pr. intermedia and P. gingivalis were lower in the case group as compared to the control group and the difference was statistically significant after 1 month (*p = 0.001).
Clinical significance: According to this study, non-invasive laser treatment has the potential to improve clinical outcomes by lowering the quantity of A.a, Pr. intermedia and P. gingivalis.
Conclusion: In both groups, a considerable decrease in the periodontal pathogens A.a, Pr. intermedia and P. gingivalis were discovered; however, the intergroup comparison was insignificant in relation to PD and CAL. The adjunctive treatment with diode laser showed better efficacy in ensuring a better periodontal treatment than SRP alone. How to cite this article: Abdullah LA, Hashim N, Rehman MM, et al.
