RESUMEN

BACKGROUND: The aim of this study was to evaluate the accuracy and quality of the information content of popular YouTube™ videos about genioplasty. MATERIALS AND METHODS: The keywords "genioplasty, sliding genioplasty and genioplasty surgery" were searched on YouTube™. It was filtered by the view count and the first 70 videos that met the inclusion criteria were evaluated. Each video was scored as ranging from 0 to 8 point and the videos were classified as bad, poor, good and excellent content. Kruskal-Wallis test was performed for statistical analysis. Intra-observer and inter-observer agreement were calculated Cohen's Kappa index. RESULTS: The videos uploaded by the individuals were significantly higher total video duration (P<0.001), number of comments (P=0.048) and viewing rate (P=0.036) than the others and the videos generally included their treatment journey. Most of the videos included bad information content. The number of likes (P=0.037), dislikes (P=0.037) and the interaction index (P=0.026) of the bad information content videos were significantly higher than the others. The other parameters did not show a significant difference (P>0.05). CONCLUSION: The results of this study would suggest that YouTube™ is not currently an appropriate source of information about genioplasty for the patients.

RESUMEN

AIM: The aim of this study was to investigate the prevalence of dental anomalies in different body mass index (BMI) percentile child and adolescent subjects. MATERIALS AND METHODS: Panoramic radiographs of 186 subjects (68 males and 118 females) were evaluated. The subjects were divided into three groups according to BMI percentile: Normal-weight (93), overweight (40), and obese (43) subjects. Supernumerary tooth, tooth agenesis, dens invaginatus, dens evaginatus, tooth impaction, taurodontism, pulp stone, and root dilaceration were assessed. RESULTS: Root dilaceration was found in 11.3% of the obese subjects and 17.5% of the overweight subjects. There was a statistically significant difference in the root dilaceration prevalence among the groups (p=0.015). However, other dental anomalies did not display statistically significant differences among the groups (p>0.05). While there was no statistically significant difference in the dental anomalies prevalence among different BMI percentile groups in males (p>0.05), a statistically significant difference in the root dilaceration prevalence was detected among different BMI percentile groups in females (p=0.036). The data were analysed using chi-square and Fisher's exact tests. CONCLUSION: The prevalence of root dilaceration was significantly greater in obese and overweight subjects than in normal-weight subjects.

RESUMEN

BACKGROUND: The aim of this study is to evaluate the relationship between frontal sinus morphology and hand-wrist bone maturation by using postero-anterior (PA) cephalometric radiographs. MATERIALS AND METHODS: The study sample consisted of 220 patients divided into 11 groups based on the hand-wrist radiographs. The right and left maximum height, width and area of the frontal sinus parameters were measured in PA cephalometric radiographs of 220 subjects aged 8-18 years. The hand-wrist skeletal maturation stages were evaluated on the hand-wrist radiographs using the method of Fishman. The Kendall tau-b values were analysed to evaluate the correlation between the hand-wrist skeletal maturation stages and the frontal sinus parameters. RESULTS: The right and left frontal sinus areas and widths were found to be larger in males than in females (p < 0.05). In males, a significant difference was observed in all frontal sinus parameters in different maturation stages (p < 0.001), while a statistically significant correlation was found in females between the left frontal sinus area, right frontal sinus height, right frontal sinus width and different maturation stages (p < 0.05). CONCLUSIONS: The relationship between frontal sinus dimensions obtained from PA cephalometric radiographs and hand-wrist maturation stages suggests that frontal sinuses can be used in determining growth and development.

RESUMEN

BACKGROUND: The ponticulus posticus (PP; Latin for little posterior bridge) has become an important anomaly of the atlas, as the use of the C1 lateral mass screw has become common in treating atlantoaxial instability. AIM: The purpose of this study was to retrospectively determine the prevalence and morphologic characteristics of PP in an orthodontic patient population using cervical three-dimensional (3-D) cone beam computed tomography (CBCT) images. MATERIAL AND METHODS: A retrospective study was conducted by selecting cervical 3-D CBCT images of 374 adolescent population and examining them for the presence and type of PP. RESULTS: 161 patients with 298 complete or partial or bilateral or unilateral PPs were identified based on the 374 cervical 3-D CBCT scans. The prevalence of posticulus ponticus was founded 43.04% in adolescent population. CONCLUSION: Our results show that the presence of this anomaly should be carefully examined using preoperative lateral radiographs before lateral mass screw placement. If a PP is suspected or confirmed on radiographs, 3-D CBCT scanning should be considered before lateral mass screw placement into the posterior arch because of the variation in the size and shape of PPs and the possibility of injury.

RESUMEN

OBJECTIVE: To compare the frequency of maxillary dental anomalies in patients affected by unilateral (UCLP) and bilateral (BCLP) cleft lip with palate and to determine whether statistical differences were present or not between cleft and normal sides in UCLP group by using cone beam computed tomography (CBCT). In addition, the frequency of those dental anomalies was compared with previous studies presenting the same population without cleft Study Design: Fifty non-syndromic patients affected by UCLP (28 patients) and BCLP (22 patients) were selected for analysis of dental anomalies by means of CBCT. The frequency of maxillary dental anomalies including tooth agenesis, microdontia of lateral incisor, ectopic eruption and impaction of canine and supernumerary tooth were examined. Pearson chi-square and Fisher's exact tests were performed for statistical comparisons. RESULTS: All patients affected by UCLP and BCLP were found to have at least one maxillary dental anomaly. The most frequently observed dental anomaly was tooth agenesis (92.5% and 86.4%, respectively) in UCLP and BCLP groups. Tooth agenesis and canine impaction were observed more commonly in the cleft side (75.0% and 35.7%, respectively) than in the normal side (57.1% and 14.3%, respectively) in UCLP group (p≯0.05). All dental anomalies were found to be higher in both cleft groups than in general populations not affected by cleft. CONCLUSION: Since patients affected by UCLP and BCLP had at least one dental anomaly and higher dental anomaly frequency as compared to patients without cleft, those patients should be examined carefully prior to orthodontic treatment.

RESUMEN

OBJECTIVE: The aim of this study was to determine and compare the reliability to accomplish of common mandibular landmarks and to determine the incidence of incisive canals, anterior looping, and lingual foramina in children from panoramic and CBCT images. DESIGN: Panoramic and CBCT images from 100 children and adolescent patients were randomly selected. In order to grade the visibility of mandibular anatomical landmarks, a four-point rating scale was used. RESULTS: In panoramic images, the mandibular canal could be observed in 92.5% of cases, with good visibility in 12.0%. The mental foramen could be observed in 44.5% of cases, while none had good visibility. Anterior looping of the mental nerve was present in 16.5% of the cases, and none had good visibility. An incisive canal could be identified in 22.5% of cases, with only 1.5% showing good visibility. The lingual foramen could be visualized in 61.0% of cases, with good visibility in 6%. In CBCT images, the mandibular canal, the mental foramen, and the lingual foramen could be observed in 100% of the cases, with good visibility in 51.0%, 98.5%, and 45.0% of cases, respectively. Anterior looping of the mental nerve was present in 26% of cases, with 2% having good visibility. An incisive canal could be identified in 49.5% of cases, with only 75% showing good visibility. CONCLUSIONS: This study confirms the applicability of CBCT images to visualize critical structures in children.
