Special Issue Information

Dear Colleagues,

Teeth impaction has always presented a challenging topic, not only for oral surgeons but also for every clinician who approaches dentistry. Over the years, impacted teeth management possibilities have widely increased, mainly because of technological developments in the dental field, which led to new diagnostic methods and modern therapeutic approaches. Nowadays, research focus is highly set on teeth impaction early prevention and non-extractive therapies, such as teeth autotransplanation and mini-invasive orthodontic recovery. Under these terms, dental impaction could become almost an opportunity instead of an insurmountable clinical problem. The aim of this Special Issue is to collect original papers that address this intriguing topic, such as narrative or systematic reviews, meta-analyses, pre-clinical studies, or clinical trials.

Background/Objectives: This study aimed to evaluate the impacts of various dental anomalies on the complexity of malocclusion. Methods: This retrospective cross-sectional study employed a case–control design. The sample comprised 140 patients, 59 cases, and 81 controls. The Index of Complexity Outcome and Need (ICON) was used to calculate a score indicating the complexity of the malocclusion. According to the ICON score, the level of malocclusion complexity was classified into easy, mild, moderate, difficult, and very difficult. The cases were subdivided into three groups based on their dental anomaly type (number, shape, or eruption anomalies). A chi-square test was used to compare the distribution of cases and controls across the ICON levels (p < 0.05). A t-test and an ANOVA with Tukey’s post hoc test were used to evaluate the differences in the ICON scores among groups (p < 0.05). Results: The mean values of the ICON score were 56.77 ± 17.1 for the cases and 47.44 ± 17.54 for the controls (p = 0.002). Most patients in the case group were within the highest three ICON levels, while most controls were in the lowest three (p = 0.022). Patients with eruption anomalies had a higher ICON score, compared to the controls and those in other dental anomaly groups (p = 0.001). Conclusions: The presence of dental anomalies increases the complexity of malocclusion. Eruption anomalies are more complex to resolve than number and shape anomalies, due to their impact on occlusion and aesthetics. Full article

Objectives: This study examined the link between impacted maxillary canines and changes in the position of adjacent lateral incisors (LIs) and first premolars (FPs), as well as opposite canines. It also explored the relationship between the position of impacted canines and the presence of palpable mucosal bulges. Methods: The clinical study involved 62 participants (35 females, 27 males; average age: 14.7 years), split equally into impacted canine (n = 31) and control (n = 31) groups. The study included 26 palatally impacted canines, 5 buccally impacted canines, 31 non-impacted contralateral canines, and 62 control canines. Three-dimensional study models assessed LI and FP positions, while CBCT analyzed vertical and horizontal positions of impacted canines and dental follicles. Clinicians evaluated the presence of mucosal bulges, and distance was measured between impacted canines and outer cortical bone radiographically. Results: Compared to controls, the LIs next to impacted canines showed significantly more rotation (13°), mesiodistal angulation (11.5°), and buccopalatal angulation. FPs showed increased rotation (10.0°) and mesiodistal angulation (8.7° more) but no change in buccopalatal inclination. Contralateral canines had significantly more rotation (11.3°) than controls. Buccally impacted canines led to greater positional differences in the LIs compared to palatally impacted canines. Follicle thickness had a moderate correlation with FP rotation and mesiodistal angulation but did not relate to LI malposition. Visible mucosal bulges indicated distances of 1.2 mm or less between the canine and cortical bone. Conclusions: This study found positional differences in lateral incisors showed altered rotation, angulation, and inclination, while first premolars had increased rotation and angulation. Buccally impacted canines showed more discrepancies for lateral incisors. A mucosal bulge may indicate impacted canine location if the impacted canine is close to the outer bone surface. Follicle thickness affected premolar position but not incisors. Full article

Background: Untreated impacted wisdom teeth can lead to complications, including delayed healing and inferior alveolar nerve damage. Delayed management is further complicated by age-related comorbidities. Aim: This study aimed to evaluate the management of impacted wisdom teeth in a teaching dental hospital and identify challenges faced by dental care providers. Materials and Methods: A retrospective radiographic study was conducted using data from electronic medical records and panoramic radiographs of patients. Independent variables included demographics and clinical details of wisdom teeth, such as type and presence of impaction, associated pathology, nerve proximity, second molar resorption, and extraction difficulty. The study assessed the evaluation of dental care provider practices in managing impacted wisdom teeth. Chi-square tests analyzed relationships between management type, provider level, and extraction difficulty. Results: Data from 270 panoramic radiographs and dental records were analyzed. Most cases were not managed (n = 216, 80%), irrespective of extraction difficulty or care provider level (undergraduate vs. graduate). There was no significant association between care provider levels and the type of management or between impaction difficulty and management type (p > 0.05). Conclusions: The findings highlight a lack of proper evaluation and management of impacted wisdom teeth, regardless of the provider’s experience. In hospital settings, all care providers should ensure the timely evaluation and management of impacted wisdom teeth to prevent complications. Full article
