Ectopic eruption of permanent first molars: a cross-sectional study in the mixed dentition Marina Viana Scarpelli Aguiar, Lucas Gonçalves Santos, Cristiane Braga Barbosa Machado da Silva, Felipe Weidenbach Degrazia, Rodrigo Hermont Cançado, et al. Clinical Oral Investigations, 2026 Introduction Ectopic eruption of permanent first molars can compromise arch development and lead to malocclusion if undetected. Identifying associated occlusal traits may enable early intervention and prevent complications. Objective To determine the frequency and occlusal characteristics associated with ectopic eruption of permanent first molars in children. Materials and methods A cross-sectional study analyzed 901 orthodontic files of children aged 5–9 years. Twenty-four patients with ectopic eruption of permanent first molars were included as the experimental group, while 23 age- and sex-matched children comprised the control group. Panoramic radiographs were used to assess molar angulation and digital dental models were used to assess arch length, arch perimeter, intercanine and intermolar distances. Data reliability was assessed using paired t-tests and Dahlberg’s formula. Statistical analysis included Shapiro-Wilk tests, independent t-tests or Mann-Whitney tests, Chi-square tests, and logistic regression to evaluate predictors of ectopic eruption. Results Ectopic eruption was observed in 2.66% of children, predominantly in the maxilla. Children with ectopic eruption exhibited significantly shorter and narrower arches compared with control, with maxillary intermolar width emerging as a significant predictor ( p < 0.05). Molar angulations and deciduous molar crown size were not significantly associated. Conclusion Ectopic eruption of first permanent molars is associated with reduced arch dimensions, particularly maxillary intermolar width. Early recognition of these occlusal patterns may facilitate timely orthodontic management and prevent space loss and secondary crowding.
Changes in biosafety practices of Brazilian orthodontists after the COVID-19 pandemic: a cross-sectional study Lucas Gonçalves SANTOS, Elio da Mata SANTOS JÚNIOR, Renata Pacífico de CARVALHO, Felipe Weidenbach DEGRAZIA, Rodrigo Hermont CANÇADO, et al. Brazilian Oral Research, 2025 The aim of this study was to assess the biosafety practices adopted during the COVID-19 pandemic that persisted in post-pandemic orthodontic clinical routines. In this cross-sectional study, 722 Brazilian orthodontists who were in the early phase of the pandemic, and 203 from the later phase, respectively, answered a 45-item questionnaire addressing basic personal information, use of personal protective equipment, biosafety protocols, and COVID-19 incidence. Descriptive statistics and chi-square tests were used to analyze the data. Most participants were infected with the coronavirus (from 10.1% to 65%). While 52.4% perceived providing care as very risky during the pandemic, this perception shifted to decreased to a moderate level of risk in the late phase of the pandemic (40.4%). The use of protective face masks/face shields decreased from 51.7% to 25.1%, as well as the use of disposable coats (from 77.1% to 45.8%). Many orthodontists discontinued the use of PFF2/N95 masks and reverted to wearing surgical masks again. Most orthodontists disinfected orthodontic bands, and photographic retractors through manual washing and autoclaving. Most participants preferred to clean their orthodontic pliers with 70% alcohol. A decline in orthodontists’ concern about biosafety during clinical appointments was observed in the late phase of the pandemic. Moreover, the need for greater specific care still persists, especially regarding the proper use of disposable coats, face shields, and surgical masks.
Efficacy of Low-Level Laser Therapy in Reducing Pain in the Initial Stages of Orthodontic Treatment Manoel Heitor Brito, Cinthya Quagliato Nogueira, Paula Cotrin, Tiago Fialho, Renata Cristina Oliveira, et al. International Journal of Dentistry, 2022 Purpose. There is no consensus about the mechanism and efficacy in alleviating pain of the lower-level laser therapy (LLLT) during orthodontic treatment. This study aimed to evaluate the LLLT effectiveness clinically in reducing pain caused by orthodontic movement that occurs in the early stages of treatment. Methods. The sample consisted of 54 patients in need of orthodontic treatment divided into two groups. A 28 experimental patients group (initial mean age: 26.84 years old) was undergone gallium-aluminum-arsenide infrared laser application on 12 points for each tooth immediately after the installation of the first alignment archwire, and a 26 patients control group (initial mean age: 29.13 years old) was undergone to no pain control intervention at all. Pain intensity was measured by using a visual analog scale, which was marked pain level (mm) reported in 06, 24, 48, and 72 hours. The perception of pain (beginning, peak, decline, and absence) was evaluated by filling up a questionnaire. To compare the intensity and perception of pain between groups, a nonparametric Mann–Whitney has been performed. Results. The experimental group showed levels (mm) at 6 ( p < 0.001 ), 24 ( p = 0.004 ), and 48 hours ( p = 0.007 ) and perception of pain (hours) in the peak ( p = 0.026 ), decline ( p = 0.025 ), and absence ( p = 0.008 ) significantly lower compared to the group control. Conclusion. Low-level laser therapy is effective in reducing pain severity caused by orthodontic forces activation, and it promotes the analgesic action lasting effect during the most painful feeling time.
Soft tissue profile changes in Angle class II patients treated with Twin Force or intermaxillary elastics—a comparison Izabel Cristina de Mendonça Campos Falcão, Fabricio Pinelli Valarelli, Luiz Filiphe Gonçalves Canuto, Renata Cristina Oliveira, Ricardo Cesar Gobbi de Oliveira, et al. Journal of Orofacial Orthopedics, 2021 PROPOSITION This study aimed to compare soft tissue profile changes in Angle class II malocclusion patients treated with a Twin Force appliance (Ortho Organizers, Inc., Carlsbad, CA, USA) or class II elastics. METHODS The sample comprised 47 class II malocclusion patients treated orthodontically without extractions, divided into two groups. Group 1 (Twin Force): 25 patients were treated with the Twin Force, with initial and final mean ages of 17.91 and 20.45 years, respectively, and mean treatment time of 2.53 years. Group 2 (elastics): 22 patients were treated with class II elastics, with initial and final mean age of 15.87 and 18.63 years, respectively, and mean treatment time of 2.75 years. The lateral cephalograms were evaluated at the initial and final stages. Intragroup comparisons were performed with dependent t-tests and intergroup comparisons were performed with independent t-tests. RESULTS Treatment-related changes in the Twin Force group included reduction of facial convexity, retrusion of the upper lip, increase of the H‑Nose distance, and decrease in Sn‑H distance, indicating improvement in facial profile. In the elastics group, treatment resulted in an increase in nasolabial angle, retrusion of the upper lip, increase of the H‑Nose distance, and decrease in Sn‑H distance, indicating improvement in facial profile. The Twin Force group showed a greater reduction of the facial convexity with treatment than the elastics group. CONCLUSIONS Class II patients treated with the Twin Force appliance showed greater reduction in facial convexity than patients treated with class II elastics. The other soft tissue changes were similar for both groups.
Treatment Effects of the Herbst Appliance in Class II Malocclusion Patients after the Growth Peak Rodrigo Hermont Cançado, Guilherme Janson, Bryan Tompson, José Carlos de Castro Alvares, Fabrício Pinelli Valarelli, et al. European Journal of Dentistry, 2021 Objective The aim of this study was to evaluate dentoskeletal changes in the treatment of Class II malocclusion with the Herbst Cantilever Bite Jumper (CBJ) appliance, associated with multibracket appliances after the growth peak, at pretreatment. Materials and Methods A sample of 37 individuals was divided into two groups: the experimental group comprised 16 patients treated consecutively for a mean period of 2.52 years with the Herbst CBJ appliance associated with multibracket appliances. A total of 21 subjects (10 males and 11 females) with Class II malocclusion and mean age at T1 of 16.08 years were followed for a mean period of 2.12 years composed the control group. Comparisons between the two groups were performed using initial and final lateral cephalograms. Comparisons between experimental and control groups at pretreatment and of the treatment changes were performed by Mann–Whitney or independent t-tests. Results Experimental group exhibited a significantly greater labial inclination of the mandibular incisors in comparison to the control group. Additionally, significantly greater corrections in overbite, overjet, and molar relationship were observed in the experimental than in the control groups. Conclusion The effects of the Herbst CBJ appliance, associated with fixed appliances after the growth peak in Class II malocclusion treatment are correction in molar relationship toward a Class I relationship, decrease of the overjet, decrease of the overbite, and mandibular incisors labial inclination.
Attractiveness of the facial profile: Comparison of Class II patients treated with twin force® or intermaxillary elastics Otávio Augusto POZZA, Rodrigo Hermont CANÇADO, Fabricio Pinelli VALARELLI, Karina Maria Salvatore FREITAS, Renata Cristina OLIVEIRA, et al. Dental Press Journal of Orthodontics, 2021 Objective: To compare the facial profile attractiveness of Class II patients treated with Twin Force® or intermaxillary elastics. Methods: Sample comprised 47 Class II patients divided into two groups: G1) TWIN FORCE - 25 patients treated with fixed appliances and Twin Force® fixed functional appliance (mean initial age was 17.91 ± 7.13 years, mean final age was 20.45 ± 7.18 years, and mean treatment time was 2.53 ± 0.83 years); G2) ELASTICS - 22 patients treated with fixed appliances and Class II intermaxillary elastics (mean initial age was 15.87 ± 5.64 years, mean final age was 18.63 ± 5.79 years and mean treatment time was 2.75 ± 0.60 years). Lateral cephalograms from pretreatment and posttreatment were used. Cephalometric variables were measured and silhouettes of facial profile were constructed and evaluated by 48 laypeople and 63 orthodontists, rating the attractiveness from 0 (most unattractive profile) to 10 (most attractive profile). Intergroup comparisons were performed with Mann-Whitney and independent t-tests. Results: At pretreatment, facial profile of the Twin Force® group was less attractive than the Elastics group. Treatment with Twin Force® or Class II elastics resulted in similar facial profile attractiveness, but the facial convexity was more reduced in the Twin Force® group. Orthodontists were more critical than laypeople. Conclusions: Treatment with Twin Force® or Class II elastics produced similar facial profile attractiveness at posttreatment. Profile attractiveness was reduced with treatment in the elastic group, and improved in the Twin Force® group. Facial convexity was more reduced with treatment in the Twin Force® group.
Attractiveness of different esthetic orthodontic wires Deric Meschiari Batista, Melissa Faccini, F. P. Valarelli, Rodrigo Hermont Cançado, Renata Cristina Oliveira, et al. Dental Press Journal of Orthodontics, 2020 OBJECTIVE The aim of this study was to evaluate the attractiveness of different types of esthetic orthodontic wires by laypeople and dentists. METHODS Five different types of orthodontic wires were evaluated: three esthetic wires (Teflon-coated, epoxy resin-coated and rhodium-coated wires), and two metallic wires (stainless steel and NiTi), as control. Monocrystalline ceramic brackets were installed in the maxillary arch of a patient presenting good dental alignment. The five evaluated wires were attached to the orthodontic appliance with an esthetic silicone elastic and photographed. The photographs were evaluated by 163 individuals, 110 dentists and 53 laypeople. The data were statistically evaluated by two-way ANOVA and one-way ANOVA, followed by Tukey tests. RESULTS There was a statistically significant difference in the attractiveness among the wires evaluated; the most esthetic was the rhodium-coated wire, followed by the epoxy resin-coated wire and, finally, the Teflon-coated wire, with no significant difference from the stainless steel and NiTi control archwires. There was no significant difference between the groups of evaluators. CONCLUSION The most attractive was the rhodium-coated wire, followed by the epoxy resin-coated wire and, finally, the least attractive wire was the Teflon-coated wire, without statistically significant difference to the stainless steel and NiTi wires, used as control.
Evaluation of the influence of mandibular third molars on mandibular anterior crowding relapse Paula Cotrin, Karina Maria Salvatore Freitas, Marcos Roberto Freitas, Fabrício Pinelli Valarelli, Rodrigo Hermont Cançado, et al. Acta Odontologica Scandinavica, 2020 Objective: To evaluate the influence of mandibular third molars on relapse of mandibular anterior crowding in orthodontically treated patients. Material and Methods: Sample included orthodontic records of 108 patients: Group 1: 72 patients (39 female; 33 male) with third molars present in the postretention evaluation stage. Group 2: 36 patients (18 female; 18 male) who did not present the third molars in the postretention evaluation stage. Panoramic radiographs and dental models were evaluated at three different stages: pre-treatment; posttreatment and postretention. Panoramic radiographs showed the presence or absence of third molars in the 3 evaluated stages and on the dental models, overbite and mandibular anterior crowding was measured by the Little Irregularity Index. For intergroup comparisons, t-tests and a multifactorial regression analysis were used. Results: There was no statistically significant difference in the relapse of mandibular anterior crowding among the groups with and without mandibular third molars at the postretention stage. Conclusion: The presence or absence of mandibular third molars did not influence the relapse of mandibular anterior crowding in orthodontically treated patients.
