“…Furthermore, the results of the present study revealed that the occurrence of infraocclusion is more frequent in second primary molars; this anomaly has higher percentages in the mandibular arch than in the maxillary arch. In children with such developmental abnormalities, space issues might pose and in such cases expansion may become essential [ 18 , 29 , 30 ]. According to previous studies, the prevalence of mandibular infraocclusion was more than that of maxillary infraocclusion (189 : 36), and in the mandibular arch, the incidence is 2 to 10 times higher than that of the maxillary arch [ 1 , 2 , 21 – 24 ].…”

Aim. To analyze the distribution and characteristics of infraocclusion among Arabian children in primary dentition and its associated dental anomalies. Methods. A radiographic analysis was performed retrospectively using digital panoramic radiographs of children attending the pediatric dental clinic of College of Dentistry, Majmaah University, Saudi Arabia, from January 2019 to May 2021. The panoramic radiographs were analyzed to assess the distribution and characteristics of infraocclusion and its associated dental anomalies. Descriptive statistics were used for comparisons using SPSS version 21.0 (IBM Corp., Armonk, N.Y., USA). The chi-square test was used to compare percentages. Results. Among the study population (542), only 40 children reported infraocclusion of 65 primary molars. Infraocclusion was common in males (90%) and very frequent in the mandibular arch ( n = 48 teeth). In the primary dentition, unilateral infraocclusion (62.5%) was very frequent than bilateral presence (37.5%). Single molars were involved in 50% of the patients, while two, three, and four molars were involved in 42.5%, 2.5%, and 5% of cases. The mandibular second primary molar was frequently affected with infraocclusion, while the maxillary first primary molar was less commonly affected. In the mandibular arch, the second primary molar (28, 58%) was more commonly affected with infraocclusion than the mandibular first primary molars and maxillary primary and secondary molars ( p < 0.05 ). The majority of the infraoccluded molars were mild (75%), followed by moderate (23.5%) and severe (1.5%). Hypodontia (12.5%) is frequently associated with infraocclusion, followed by supernumerary teeth (5%) and radix entomolaris of the first permanent mandibular molars (5%). Infraocclusion was more in the second primary molar mandibular arch, while in the maxillary arch, the first primary molars were commonly affected ( p > 0.05 ). Conclusion. In Arabian children, infraocclusion was commonly observed in mandibular second primary molars. Unilateral infraocclusion is a mild type of infraocclusion frequent in Arabian children. Numerical anomalies such as hypodontia and supernumerary teeth are associated with infraocclusion.

“…Rapid maxillary expander (RME) and leaf expander have also been shown to produce maxillary expansion similar to dental and skeletal changes. 39 Furthermore, a transverse sagittal maxillary expander (TSME) can transversely cause a maxillary expansion in patients suffering from maxillary hypoplasia. 40 Last but not least, the option will be to surgically expose the canine and bring it to the arch orthodontically.…”

Objectives. This study aimed to analyze the inter-molar width and skeletal base class to predict maxillary canine impaction in permanent dentition. Methods. This cross-sectional study was carried out between September 2021 to March 2022. Patients aged between 13 and 20 years were recruited. These patients’ cone-beam computer tomography(CBCT), lateral cephalogram, and dental casts were collected and analyzed. For statistical analysis, T-test and Chi-square tests were applied. Results. A total of 92 patients were enrolled in this study. Inter-molar width was significantly decreased in patients with impacted canine( P < .001). The skeletal base classification was statistically significant when compare with intermolar width( P < .05). The location of impaction ( P = .060), type of impaction( P = .435), and side of impaction( P = .239) were determined to be statistically insignificant. Conclusion. The Inter-molar width was decreased in patients with impacted canine; therefore, it may be a potential risk factor. The skeletal classification was found to affect inter-molar width in impacted canine patients.

“…Rapid maxillary expansion (RME) is an orthopedic procedure for the resolution of maxillary constriction in growing patients [ 9 ], whereas surgically assisted rapid maxillary expansion (SARME) is a treatment alternative for adult patients with a mature skeletal structure whose ossified sutures are resistant to orthopedics forces [ 10 ]. As reported by several authors, the age limit for orthopedic maxillary expansion is 14–18 years [ 11 , 12 ].…”

Aim: The aim of the present study was to investigate modifications in electromyographic activity of temporal and masseter muscles before and after surgically assisted rapid maxillary expansion (SARME) in adult subjects. Materials and Methods: Data from 20 patients with unilateral posterior crossbite were selected retrospectively from the Orthodontics Department of the University of Genoa and the Department of Biomedical Surgical and Dental Sciences of the University of Milan, Fondazione IRCCS Ca’ Granda, Ospedale Maggiore Policlinico Milan. Inclusion criteria were set as skeletal class I; adult patients (age > 18); good general health; patients with a transverse maxillary deficiency with unilateral posterior crossbite and maxillary constriction ≥ 5 mm; Superficial electromyographic (EMG) examinations at T0 and T1. Exclusion criteria were smoking, metabolic bone diseases (e.g., hyperparathyroidism, vitamin C deficiency), chronic use of corticoids before or during treatment, parafunctional habits (e.g., bruxism), and temporomandibular joint dysfunction. The Shapiro–Wilk test was performed to check whether the data were normally distributed. Differences for each variable before and after SARME were analyzed with a paired t-test (p < 0.05). Results: The statistical analysis demonstrated no statistically significant differences between the EMG values taken before and after SARME regarding the standardized electrical activity of the masticatory muscles (masseter and anterior temporalis (p > 0.05)). Conclusions: Considering the specific conditions of this study, it can be concluded that SARME did not alter the EMG activity of the masseter and temporal muscles. The present study has shown that the masticatory musculature evaluated after approximately 8 months of therapy can adapt well to SARME.
