The objective of this research was to determine the frequency of soft tissue calcifications in digital panoramic radiographs of patients over 18 years old treated at the Imágenes Estomatológicas Radiological Diagnostic Center, Lima, Peru, in 2015-2016. The population consisted of 500 digital panoramic radiographs of patients over 18 years old who were treated between 2015 and 2016 and had a diagnosis of soft tissue calcification. An observational, retrospective, cross-sectional, and descriptive study was conducted. A formula was used to calculate the representative sample, which consisted of 64 digital panoramic radiographs. The following variables were collected: sex, age, radiographic findings, type, anatomical location, and anatomical quadrant. Data entry and statistical analysis were performed using SPSS version 21. The results showed that 100% of the patients over 18 years old presented soft tissue calcifications. Females were more frequent, representing 75% of cases, and bilateral findings were more common, with a frequency of 64.1%. The most frequent type of calcification was the stylohyoid ligament calcification, found in 62.5% of cases as a unique finding, 33.9% associated with another calcification, and 3.6% associated with two calcifications. The study concluded that soft tissue calcifications were frequent in patients over 18 years old.

The objective of this study was to determine the relationship between condylar morphology images obtained through CBCT and panoramic radiographs in patients from the Cirmax center. This was a cross-sectional relational study, and the sample consisted of 48 tomographies, each including its corresponding panoramic radiograph. The morphology of the right and left condyles was evaluated through CBCT images and panoramic radiographs. A data collection card was used to evaluate the mandibular condylar morphology, which was divided into two segments: evaluation through CBCT and evaluation of panoramic radiograph morphologies. Results: In CBCT, normal morphology was the most prevalent at 45.12%, while in panoramic radiographs, the most prevalent morphology was rounded, accounting for 50% of the total sample. In the images of the right and left condyles obtained from CBCT, normal morphology was the most prevalent at 52.1% and 45.8%, respectively; while in the panoramic radiograph images of the right and left condyles, the most prevalent morphology was rounded, with 52.1% and 47.9%, respectively. According to sex, in CBCT, normal morphology images had a higher prevalence in males at 47.2% and females at 45.5%; while in panoramic radiographs, 33.5% of males had a rounded morphology, much lower than the 58.5% in females. The Fisher's exact test was performed, obtaining p-values less than 0.05, verifying that there are statistically significant relationships between the condylar morphology images obtained through CBCT and those obtained through panoramic radiographs.

The objective of this study was to determine the prevalence of dental anomalies in number in patients attending the Orthodontics Service of the Police National of Peru Dental Clinic in Angamos, Lima, from 2010 to 2016. The study was descriptive and retrospective. The sample consisted of 154 conventional and digital panoramic radiographs, clinical records, and orthodontic files, with ages ranging from 6 to 25 years. A data collection form was designed specifically for the objectives of the study. The results were analyzed using descriptive statistics with frequency analysis. The study concluded that the prevalence of dental anomalies in number was 38 cases (24.7%), with hypodontia found in 32 patients (20.8%) and hyperdontia in 6 (3.9%). The upper jaw was the most affected (47.37%), followed by the lower jaw (13.16%) and both jaws (13.16%). The most affected teeth by agenesis were the lower third molars (34.5%), followed by the upper third molars (30.9%). Canines were also among the most affected teeth by agenesis. Regarding hyperdontia, 7 supernumerary teeth were found, with 3 in the parapremolar region, 2 in the molar region, and 2 in the premaxilla (mesiodens and lateral). No cases of distomolar were found. Finally, regarding sex, it was concluded that males were more affected by dental anomalies in number with 22 cases (28.2%) and were the only ones with hyperdontia. No statistically significant differences were found. It is recommended that general dentists include this valuable auxiliary examination as part of a protocol, as it plays an important role in diagnosis and treatment.

The purpose of the study was to determine the frequency of vertical asymmetry of the mandibular condyle based on the Habets technique in digital panoramic radiographs of patients who visited the Vilcor dental imaging center in Lima, Peru. The approach was quantitative, basic, and observational, with 150 panoramic radiographs evaluated. The technique used was observation, and a data collection form validated by expert judgment was employed. It was found that when applying the Habets asymmetry index with a 3% cut-off, there was a prevalence of condylar asymmetry in the vertical plane of 58%, followed by mandibular ramus asymmetry at 31.30%, and the least prevalent was the combined condyle and ramus asymmetry at 12%. Regarding the vertical asymmetry of the condyle and ramus, the average for the right side was 50.59 mm, and for the left side, it was 50.31 mm, leading to a low prevalence of asymmetry at 12%. By sex, there was equal prevalence of asymmetry between females and males at 6%. By age, for the condyle and ramus, the prevalence of asymmetry was 4% for those up to 29 years old, 6.6% for those between 30 and 59 years old, and 1.3% for patients over 60 years old. The conclusion is that there is a low prevalence of mandibular condyle and ramus asymmetry evaluated in digital panoramic radiographs of patients who visited the Vilcor dental imaging center in Lima, Peru.

This research determined the characterization of the impaction of permanent mandibular second molars in patients treated at the dental teaching clinic of the Universidad Privada Juan Pablo II in 2017. Materials and Methods: This was an observational study with a descriptive, cross-sectional design and a retrospective type. A total of 200 panoramic radiographs of patients over 15 years of age, of both genders, treated in 2017, were used. The representative sample consisted of 111 panoramic radiographs. Data collection and statistical analysis were performed using SPSS version 21.0. Results: The frequency of impaction of permanent mandibular second molars was 9.9%. The radiographic angulation according to the Occlusal Plane Angle (APO) was 130.64 ± 10.337; the Interplanar Occlusal Angle (AIP) was 42.91 ± 6.503, while the Intermolar Angle (AIM) was 34.91 ± 6.348. The impaction inclination of the mandibular second molars was mesioangular, and radiographic pathologies of adjacent structures to the impacted second molars were observed. Bone defects were found in 18.21% of cases, and carious lesions also accounted for 18.21%. The gender with the highest impaction frequency was male, with 54.5%, while female accounted for only 45.5%. The most impacted mandibular side was the right, with 72.7% (8), while the left had 27.3% (3). Conclusion: The prevalence of impaction of permanent mandibular second molars is low.

(Universidad Privada Norbert Wiener, 2022-08-15) Meléndez Vela, Anita Milagros; Vergara Pinto, Brenda Roxana
Materials and Methods: In this observational, analytical, cross-sectional study, 274 digital panoramic radiographs were analyzed, belonging to patients aged 6 to 45 years. A statistical analysis was conducted, with a 95% confidence level (significance level 0.05). Results: In the study, 174 patients were female. The mean distance of the LM (Lower Molar) to the PO (Occlusal Plane) ranged from 4.81 mm to 12.01 mm, while the distance of the FM (Mental Foramen) to the PO ranged from 0.92 mm to 7.91 mm. The mean distance of the LM to the BA (Bony Arch) ranged from 12.65 mm to 15.46 mm, and the distance of the FM to the BA ranged from 13.96 mm to 17.28 mm. A significant difference (p<0.05) was found in all distances according to age and between the LM-BA and FM-BA distances according to sex. Conclusions: The anesthesia technique for blocking the inferior alveolar nerve should be applied between the lower occlusal plane level, not exceeding 12.01 mm and 7.91 mm (LM and FM respectively), with a needle insertion depth ranging between 12.65 mm - 15.46 mm and 13.96 mm - 17.28 mm (LM and FM respectively).

The objective of this study was to determine the relationship between the location of lower third molars according to Pell and Gregory and the proximity to the mandibular canal according to Ezoddini in panoramic radiographs of patients aged 18 to 50 years treated at the Ceramax Radiological Center in 2022. Methodology: A cross-sectional, observational, correlational, and retrospective study was conducted with a sample of 150 panoramic radiographs and a total of 216 lower third molars. A data collection sheet was created to record gender, age group, location according to Pell and Gregory, and proximity to the mandibular canal according to Ezoddini. Results: The most frequent location according to Pell and Gregory was Class I Level A (53.2%), while the most frequent proximity to the mandibular canal according to Ezoddini was "There is contact between the root and the canal" (42.6%). It was determined that there is a statistically significant association (p = 0.000) between both variables. On the other hand, there was no statistically significant relationship between the location of lower third molars according to Pell and Gregory with gender and age group (p > 0.05). However, there was a statistically significant relationship between proximity to the mandibular canal according to Ezoddini with gender and age group (p < 0.05). Conclusion: There is a relationship between the location of lower third molars according to Pell and Gregory and proximity to the mandibular canal according to Ezoddini in panoramic radiographs of patients aged 18 to 50 years treated at the Ceramax Radiological Center in 2022.
