“…Initial screening of databases resulted in 353 studies, with 285 excluded as they were duplicates. From the analysis of the titles and abstracts of the 68 eligible papers, fourteen studies (McDonald & Pitt Ford 1994, Barwick & Ramsay 1996, Brodin et al 1996, Sano et al 2002, Bauss et al 2008a,b, Babacan et al 2010, Salles et al 2013, Sabuncuo glu & Ersahan 2014, Ersahan & Sabuncuo glu 2015, Abu Alhaija et al 2019, Abu Alhaija & Taha 2020 met the inclusion criteria and were selected for fulltext reading.…”

“…Two studies (Bauss et al 2008a,b) were excluded due to the methods used to evaluate pulp status (cold sensibility test, periapical radiographs and crown colour alteration). Therefore, twelve studies were included in the present review (McDonald & Pitt Ford 1994, Barwick & Ramsay 1996, Brodin et al 1996, Sano et al 2002, Babacan et al 2010, Salles et al 2013, Sabuncuo glu & Ersahan 2014, Ersahan & Sabuncuo glu 2015, Abu Alhaija et al 2019, Abu Alhaija & Taha 2020.…”

“…As for the type of tooth movement, one study reported tipping movement (Abu Alhaija et al (Brodin et al 1996), and three studies reported alignment and levelling (Salles et al 2013, Ersahan & Sabuncuo glu 2018, Abu Alhaija & Taha 2020. However, only one study (Salles et al 2013) specified the movements applied to align and level the teeth.…”

“…One study, due to the use of a device for rapid maxillary expansion, described the force application as one-quarter turn once a day (Babacan et al 2010). Three studies did not reference the force applied (Ersahan & Sabuncuo glu 2018, Abu Alhaija et al 2019, Abu Alhaija & Taha 2020.…”

“…However, these systematic reviews only assessed a small number of studies that evaluated changes in pulpal blood flow from orthodontically moved teeth or included studies that evaluated such outcomes using less accurate diagnostic methods to determine the pulp status. Besides, since these systematic reviews were conducted, new evidence (Sabuncuo glu & Ersahan 2016, Ersahan & Sabuncuo glu 2018, Abu Alhaija et al 2019, Abu Alhaija & Taha 2020 on the subject has appeared, requiring a further systematic review that includes this new data.…”

Objectives To compare blood flow (BF) changes of teeth subjected to orthodontic forces during curve of Spee (COS) leveling using different archwires (AW). Material and methods Thirty subjects with COS > 5 mm were randomly assigned (1:1:1) into three groups based on the AW used: group 1: 0.017 × 0.025-inch stainless-steel (SS)AW, group 2: 0.019 × 0.025-inch SSAW, and group 3: 0.021 × 0.025-inch β-titanium (TMA)AW. In the 3 groups, a 5 mm-depth reverse COS was placed in the AWs. A laser Doppler flowmeter was used to measure BF at different time intervals (T0–T4). Results In the 3 AWs group, BF of all measured teeth was reduced 20 min after force application. Afterwards, the BF values started to increase until the baseline values were almost restored within 1 week. Differences in BF changes between the extrusion and intrusion subgroups were observed within groups 1 and 3 during the first 20 min of force application (P < 0.05). Similar BF changes were recorded using the 3 different AWs. BF changes were associated with tooth type and the amount of COS depth change. Conclusions During CoS leveling, similar BF changes were recorded using the 3 different AWs. Tooth type and the amount of COS depth change were associated with BF changes within the first 20 min of force application. Greater BF reduction was found in premolars compared to incisors during the first 20 min of AW placement. Clinical relevance It is important to select a type of applied forces that minimally affect the BF. Intrusive forces appeared to have lower negative effects on the BF of teeth during COS leveling.
