In this article, I would like to look at some serious considerations you may have to “buy” into before you continue to walk in a Torah submissive way. One the one hand, scripture such as Isaiah 55:1 (See also Rev. 21:6 & 22:17) says there is no cost for Living Water: “Ho! Every one who thirsts, come to the waters; and you who have no money come, buy and eat. Come, buy wine and milk without money and without cost.” On the other hand, Yeshua tells us to “count the cost” (Luke 14:25-35) of discipleship before embarking. So, God doesn’t charge us anything, but people will. Below is a partial list of some of the costs you might have to pay.

Abstract Background Proposed skeletal changes achieved by functional appliances (FA) with reference to stable structures (structural method) have received relatively little attention compared to conventional cephalometric measurements (conventional method). Using the two methods, the aims of this study were to (1) determine the skeletal changes as a result of FA treatment; and (2) identify the skeletal changes associated with upper-airway volume and minimum cross-sectional area (MCA). Methods Pre- and post-treatment CBCT scans were selected from 73 FA treated children (37 girls and 36 boys; mean age 12.0 years) and 73 children as a control group (matched for chronological age, skeletal age, gender, and mandibular inclination) who received orthodontic treatment using only fixed appliances (no FA). Skeletal, upper-airway volume, and MCA changes were analysed by applying both structural and conventional methods. Results The FA group had significant skeletal effects compared with the control group (both methods; p = 0.04 – p < 0.001). The horizontal displacement of pogonion (both methods) and the hyoid bone, together with a forward mandibular rotation (structural method), had positive effects on upper-airway volume and MCA (p < 0.05). Conclusions The horizontal changes in pogonion (both methods) and the hyoid bone, as well as a forward mandibular rotation (structural method), have a strong association with changes in the upper airway. The conventional method underestimates FA treatment effects. These results may influence the management of growing class II patients with compromised upper airways.

Abstract Objectives To investigate the prevalence of posterior tongue tie in orthodontic patients using numerical and clinical assessment methods in order to identify an association between posterior tongue tie and transverse maxillary deficiency. Materials and methods Seventy-nine participants from an orthodontic clinic were divided into two groups. The first group of 44 patients exhibited a skeletally narrow maxilla and required maxillary skeletal expansion (MSE group) and 35 patients without a transverse discrepancy comprised a control group. Posterior tongue tie was examined by the Kotlow tongue tie classification, tongue range of motion ratio (TRMR) and via a clinical assessment. The prevalence of posterior tongue tie was compared between the two groups. Results There was no significant difference in the level of the Kotlow classification grade between the two groups (p > 0.05) and the overall majority was diagnosed as normal. However, a higher proportion of posterior tongue tie was found in the MSE group than in the control group by clinical assessment (MSE group, 72.7%; control group, 42.9%; p = 0.005). The proportion of TRMR grade 2 was also higher in the MSE group than in the control group (p = 0.001). Of the subjects diagnosed with posterior tongue tie by clinical findings, approximately 94% showed TRMR grades 2 or 3. Conclusions A clinical assessment of posterior tongue tie was found to be simple and accurate, whereas a numerical assessment alone provided diagnostic difficulty. Considering the high prevalence of observed posterior tongue tie in the MSE group, there was a significant association between posterior tongue tie and transverse maxillary deficiency.

Abstract Objective The purpose of this study was to assess the current literature on the effectiveness of rapid palatal expansion (RPE) in assisting the spontaneous eruption of impacted maxillary canines. Materials and methods Four electronic databases were searched (Pubmed, Scopus, Web of Science, Embase) by applying appropriate Medical Subject Headings (MeSH). Two authors independently and systematically reviewed the literature. Randomised controlled trials (RCTs) and prospective controlled clinical trials (pCCTs) were identified and selected. The Cochrane Collaboration’s risk of bias tool and the risk of bias in non-randomised studies of interventions (ROBINS-I) were used to assess the quality of the obtained articles. Spontaneous canine eruption was used as a primary outcome. Results Three RCTs and two pCCTs met the inclusion criteria. One study was assessed at a high risk of bias in the RCT group, while the remainder were at an unclear risk of bias. Both pCCTs were classified as a moderate risk of bias based on the ROBINS-I tool. The success rate of canine eruption following RPE, with or without additional treatment, ranged from 65.7 to 85.7%, which was statistically significantly different from the control group. Conclusion RPE appears to improve the position of displaced maxillary canines and increase the likelihood of spontaneous eruption. However, there is a shortage of high-quality evidence to conclude that RPE can be an effective treatment option for impacted maxillary canines.
摘要目的评价快速腭扩张术(RPE)辅助上颌埋伏尖牙自然萌出的疗效。材料与方法检索Pubmed、Scopus、Web of Science、Embase四个电子数据库，采用合适的医学主题词(MeSH)进行检索。两位作者独立而系统地回顾了文献。确定并选择随机对照试验(RCTs)和前瞻性对照临床试验(pCCTs)。使用Cochrane Collaboration的偏倚风险工具和非随机干预研究的偏倚风险(ROBINS-I)来评估获得的文章的质量。自发性犬疹被用作主要结局。结果3项rct和2项pcct符合纳入标准。在RCT组中，一项研究被评估为高偏倚风险，而其余研究的偏倚风险不明确。根据ROBINS-I工具，两项pcct均被归类为中等偏倚风险。与对照组相比，RPE术后犬出疹成功率在65.7 ~ 85.7%之间，与对照组相比差异有统计学意义。结论RPE可以改善上颌牙移位的位置，增加自然出牙的可能性。然而，缺乏高质量的证据表明RPE可以作为上颌埋伏牙的有效治疗选择。

Abstract Aim Using a thermal camera, the aim of the study was to determine pulp chamber temperature changes during orthodontic bonding produced as a result of variations in curing light sources, different curing distances and bracket types. Methods One hundred sixty maxillary premolar teeth were sectioned into two halves and embedded into acrylic moulds. Four curing light sources were used which further divided the overall sample into Halogen, light emitting diode (LED), powered LED, and high-power LED groups. Additional subgroups were created according to the applied curing distances (5 mm, 10 mm) and different bracket types (metallic or ceramic). A standardised bonding procedure was performed and pulp chamber temperature changes were evaluated using a thermal camera. Statistical analysis was performed using a three-way ANOVA. Results The Halogen light curing group revealed a significantly higher temperature rise in the pulp chamber compared to the other groups. A shorter curing distance produced increases in pulpal temperature. There was no significant effect as a result of the bracket type. Conclusions None of the curing light sources exceeded the critical value for pulp chamber temperature rise. The primary desirable outcome was the lowest temperature increase noted with the high-power LED unit. The secondary outcome related to the different brackets revealed no difference relative to pulp chamber temperature change. From a clinical perspective, high-power LED units could be safely used.

Abstract This case report describes a 13-year-old Caucasian male who presented with a Class I dental relationship on a mild Class II skeletal base and an associated unilateral Brodie bite on the right side but an ideal anterior overjet and overbite. The posterior teeth in the first quadrant had supra-erupted due to a lack of opposing occlusion. The treatment comprised two phases, the first of which involved miniscrew-based intrusion of the maxillary right buccal teeth followed by non-extraction, full upper and lower pre-adjusted edgewise appliances during a second phase. A satisfactory occlusal result was achieved in 24 months.
