- Aims and objectives: The aims of this study were to compare the anesthetic effect of a lidocaine/prilocaine (L/P) topical anesthetic with placebo on pain from needle sticks and to compare the anesthetic effect of the L/P topical anesthetic with an infiltrative anesthetic on pain from orthodontic miniscrew placement. Materials and methods: Pain elimination was analyzed from two interventions: (a) needle stick and (b) miniscrew insertion. When assessing pain from needle stick, one side of the mandible received 2.5% lidocaine/2.5% prilocaine topical anesthetic, and the other side received placebo. When evaluating pain from miniscrew placement, one side of the mandible received L/P topical anesthetic and the other side received infiltrative anesthetic. The findings were recorded on a Visual Analogue Scale after needle stick and after miniscrew placement. Subjective assessment was analyzed by a questionnaire. Results: The L/P topical anesthetic significantly eliminated the pain from needle stick (Mann–Whitney test of medians, 29.0 vs 0.0, respectively, p<0.001). However, the injection anesthetic eliminated the pain from the miniscrew placement better than the L/P topical anesthetic (Mann–Whitney test of medians, 0.0 vs 5.5, respectively, p<0.001). Eighty percent of the subjects felt more comfortable with L/P topical anesthetic than injection anesthetic. Pain from needle stick pain was reported to be the most uncomfortable part of the study. Conclusion: The L/P topical anesthetic efficiently eliminated pain from needle stick. The L/P topical anesthetic did not completely eliminate pain from miniscrew placement as the injection anesthesia, but it did reduce pain to tolerable levels. Clinical significance: L/P topical anesthetics can significantly eliminate pain from needle stick injections, and L/P topical anesthetics can reduce pain from orthodontic miniscrew placement to tolerable levels. © Jaypee Brothers Medical Publishers. 2021 Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by-nc/4.0/), which permits unrestricted use, distribution, and non-commercial reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

- Aim: The aim of this study is to investigate the caries situation in a group of Swedish adolescents, who were scheduled for orthodontic treatment with fixed appliances. Materials and methods: An age- and gender-matched control group was selected from the same city (Malmö, Sweden). Caries and fillings on smooth surfaces and fillings on occlusal surfaces were diagnosed clinically and caries and fillings on approximal surfaces by bitewings. Numbers of mutans streptococci (MS) and lactobacilli (LB) were analyzed in saliva. Results: There were no significant differences regarding manifest caries lesions and fillings on smooth surfaces. Numbers of occlusal-filled surfaces (FS) and approximal decayed and filled surfaces were around 10%, but did not differ between the groups. However, 53% had approximal enamel caries lesions in the test group and 46% in the control group. The prevalence of approximal decayed surfaces (DS) and FS was low in both groups, 0.57 ± 1.41 in the test group and 0.65 ± 1.38 in the control group (p > 0.05), i.e., somewhat more DS in the control group (p < 0.05). Most individuals had low/medium counts of cariogenic bacteria in their saliva and less than 10% high counts in both groups. Conclusion: Most Swedish adolescents who have been scheduled for treatment with fixed appliances appear to have a low-to-medium caries risk nowadays. However, around 10% of all approximal tooth surfaces of premolars/molars had enamel caries and one-third of the individuals had medium/high counts of cariogenic bacteria in their saliva, which may be risk factors for future caries during orthodontic treatment. © The Author(s).

Tidskriftsartikel (refereegranskat)abstract
- Aim: This study aims to test the feasibility and effectiveness of a novel pacifier-based saliva collection method on children and infants in comparison to an oral swab-based saliva collection method. Materials and methods: This study was performed during spring 2018 in a clinical non-sponsored setting at Queen Silvia Children's Hospital pediatric emergency ward. Saliva collection was performed by comparing oral swab (Salimetrics® SalivaBio's Children's Swab) with a pacifier-based saliva collection method (Salivac®). All participating children used both saliva collection systems. The amount of saliva collected in 2 minutes was measured. The amount of time needed for the healthcare professional was recorded. Parental preference was evaluated by a questionnaire. Results: No statistically significant difference was observed in collected saliva (174 µL for pacifier-based saliva collection and 158 pL for oral swab). The healthcare professional spent significantly less (p < 0.001) mean time with the pacifier-based saliva collection method than with the oral swab (31 vs 150 sec). A total of 48 out of the 52 caretakers preferred the pacifier-based saliva collection method compared to the oral swab. Conclusion: The novel pacifier-based saliva collection method proved to be a feasible, appreciated, and effective way of collecting saliva that simplifies the saliva collection method among children and infants. Clinical significance: The pacifier-based saliva collection method simplifies saliva testing. The closed vacutainer system minimizes the risk of saliva contamination and opens up for novel home testing strategies. © 2021 Jaypee Brothers Medical Publishers. All Rights Reserved.

- Background: Surface characterization of dental implants allows us to better understand the effects of the implant on the host biological response. In this study, we analyzed and compared these characteristics among implants commercially available in South Africa. Materials and methods: Eight implants from different manufacturers were chosen for analysis (Touareg, ICE, (R)Evolutions, Uniti, AnyRidge, MIS, Ivory-QSI, Southern), using scanning electron microscopy (SEM), interferometry, and energy dispersive X-ray spectroscopy to study the surface chemical composition and morphology. Results: The results indicate that variations in manufacturer processes result in implant surfaces that are distinctly different from one another. Most implants presented a moderately rough surface with sandblasted-only implant surfaces having a lower mean value of Sa when compared with sandblasted and acid-etched surfaces. Carbon contamination was detected on all the implants and that of aluminum on five implant surfaces. Ca and P were detected on the surface of Touareg implants, indicating the manufacturer's attempt to enhance osseointegration. Conclusion: The surface of the implants showed a range of chemical, physical properties, and surface topographies.

- To evaluate the shaping ability of the XP-endo shaper file system in maxillary molars, representing root canals with variation in morphology. Materials and methods: Twenty maxillary molars were instrumented according to recommended protocols. Pre- and postoperative microcomputed tomography (CT) scans were performed and the root canals classified according to canal type and curvature. The volume change, number of strokes needed to prepare the canals and the size of the 0.04-tapered gutta-percha cone that was adapted in the canal were recorded. Results: XP-endo shapercreated a significant change in volume after instrumentation in all the canals, with the biggest change found in the DB canals, followed by the MB1 and the P canals, both at full length and in the apical 4 mm. The number of strokes needed to achieve working length and final shape did not differ between the various root canals. Although not significant, the number of strokes needed to prepare the root canal increased with severity of the curvature, but the severity of the curvature did not result in increased removal of dentin in the apical 4 mm. It was possible to achieve a final root canal size where a 0.04-tapered gutta-percha cone could be adapted. Conclusion: The XP-endo shaper was a safe and effective instrument to achieve a root canal preparation of at least size 30 and a 0.04 taper. Clinical significance: The clinical performance of XP-endo shaper was to some extent dependent on preoperative volume and curvature of the root canal.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To evaluate the presence of work-related musculoskeletal disorders (WRMSDs) among undergraduate dental students of the College of Dentistry, King Saud University (KSU), Riyadh, Saudi Arabia.Materials and methods: A questionnaire-based cross-sectional survey was conducted in 2017 and distributed to150 undergraduate female, and male dental students of KSU who had started to work with patients in the clinic or with manikins. Data were collected related to WRMSDs.Results: Nearly, 142 (95%) students returned the completed questionnaire, 88 (62%) were females and 54 (38%) were males. The results of this study indicate that musculoskeletal symptoms among dental students of KSU are high. Females generally reported more WRMSDs. Seventy-two percent of females and 41% of males reported frequent headaches. Fourteen percent of females and 6% of males had some musculoskeletal pain disorders before joining the dental profession, whereas 68% of females and 43% of males reported pain attributed to their clinical dental work. In the majority of females (67%) and males (61%), the onset of pain was gradual. Commonly reported pain sites in both females and males were the neck, shoulder, upper and lower back. The most common pain sites, among females were shoulder and neck, and upper- and lower-back among males.Conclusion: The WRMSDs can affect the dental professionals from the early stages of their clinical carrier, even as dental students. Concrete steps are required to prevent the occurrence of WRMSDs among dental students by providing them the detailed knowledge about theoretical and practical aspects of dental ergonomics. Higher prevalence of WRMSDs among female dental students indicate that female dental professionals need to be extra vigilant to adhere to the principles of dental ergonomics from the very beginning of their clinical career.Clinical significance: The awareness to implement the principles of dental ergonomics among dental students can help to prevent early development of WRMSDs among them. The inclusion of dental ergonomics as a detailed stand-alone subject in the dental curriculum before the start of clinical training can contribute minimize the risk of WRMSDs throughout the professional life of the dentists.
