The management of labial hemangiomas may be challenging for functional and esthetic reasons. In the present case, a 12-year-old boy with a large congenital hemangioma in the area of the upper lip was referred due to esthetic concerns and a history of treatment failure. The lesion was not pulsatile on palpation, and sclerotherapy with 5% ethanolamine oleate was proposed. Although the lesion became less purple after 6 sessions of sclerotherapy, indicating a decrease in vascularization, the size remained almost the same. Therefore, surgery was considered to improve lip symmetry. Arteriography showed the lesion was supplied by branches of the facial artery, which were then embolized with 3% polidocanol foam. Subsequently, the patient underwent 2 surgical interventions with a high-power diode laser, and satisfactory results were obtained.

The aim of this case report is to increase awareness of this phenomenon by describing the clinical presentation of a patient from Nigeria with conspicuous yellow discoloration of the floor of the mouth and soft palatal mucosa. Attending clinicians should seek clinicopathologic correlations of yellow mucocutaneous discoloration, most notably jaundice associated with hepatitis.

The primary mandibular left central incisor (tooth O) was avulsed when the child was 2.7 years of age. At a follow-up visit 2.5 years later, the permanent mandibular left central incisor (tooth 24) was erupting and presented a change in color along with a reduction in the enamel thickness. A temporary restoration of the hypoplastic defect was performed when the child was 7.7 years of age. This conservative approach was chosen based on the child's behavior and because the lesion boundary was located near the free gingival margin due to the eruption stage of the tooth. The procedure was carried out without local anesthetic, utilizing a resin-modified glass ionomer cement and cotton roll isolation. This patient-friendly approach allowed simplification of the steps involved in the process. The child and his guardian were satisfied with the temporary restoration, and the boy regained his self-reliance regarding dental care.

The present cross-sectional study used the 6-minute walk test (6MWT) to compare the physical proficiency of children and adolescents who had a diagnosis of MB with that of children and adolescents who demonstrated nasal breathing (NB). A total of 80 patients aged 7 to 15 years were divided equally (n = 40) into MB and NB groups and underwent 2 6MWTs at 15-minute intervals. Cardiorespiratory variables--heart rate, respiratory rate, and peripheral oxygen saturation--were analyzed at 3 observation periods (OPs): OP₀, baseline; OP₁, after the first 6MWT; and OP₂, after the second 6MWT. In addition, the distance traveled and the modified Borg scale (MBS) score, which measures perceived exertion, were recorded at OP₁ and OP₂. Statistical analyses included repeated-measures analysis of variance and t tests for continuous variables and the chi-square test for categorical variables, and the significance level was set at P < 0.05. Statistically significant increases in heart and respiratory rates from OP₀ to OP₂ were observed among both male and female patients in the MB group. Peripheral oxygen saturation showed a statistically significant increase from OP₀ to OP₂ among male patients in the MB group. Male patients in the MB group also showed significant increases in MBS scores from OP₀ to OP₁ and from OP₀ to OP₂. In female patients in the MB group, MBS scores increased significantly only from OP₀ to OP₂. Intergroup comparisons of mean values revealed statistically significant differences between male MB and NB patients for both the total distance covered and for MBS scores at both OP₁ and OP₂, with patients in the MB group traveling a shorter distance and reporting greater exertion. The present study established the utility of the 6MWT for assessment of physical proficiency in children and adolescents with varied breathing patterns. The results indicated that MB had a significant negative impact on physical proficiency in male children and adolescents.

The purpose of this in vitro study was to quantify and compare the quality of the marginal seal when different materials and bonding techniques were used to restore endodontic access cavities in zirconia cylinders. Fifty custom zirconia cylinders (10.0 mm in diameter × 14.0 mm in height; wall thickness of 1.5 mm) were prepared with simulated endodontic access cavities (5.0 mm in diameter). The cylindrical specimens were divided into 5 groups, each assigned a different method of access cavity restoration (n = 10 per group): direct glass ionomer cement restorations; direct composite resin restorations adhesively bonded without prior aluminum oxide (Al₂O₃) particle abrasion of the zirconia surface; direct composite resin restorations adhesively bonded after Al₂O₃ particle abrasion of the zirconia surface; custom zirconia inlays adhesively bonded without Al₂O₃ particle abrasion of the zirconia surface or inlay; and custom zirconia inlays adhesively bonded after Al₂O₃ particle abrasion of the zirconia surface and inlay. Specimens were immersed in 2% methylene blue solution and stored in a humidified incubator at 37°C, and dye penetration was quantified with a spectrophotometer (at 450 nm) every 7 days for 28 days. Statistical analysis was conducted using 2-way analysis of variance with the Tukey test and chi-square analysis. Statistically significant differences in dye penetration were observed, with microleakage influenced by the restoration material and bonding protocol. Zirconia inlays placed after Al₂O₃ abrasion exhibited the least leakage, showcasing significantly superior sealing compared with direct composite resin restorations without Al₂O₃ abrasion. The results indicated that Al₂O₃ particle abrasion is essential for secure bonding of restorations to zirconia. The results of the study confirm that glass ionomer cement should be avoided for long-term restoration of access cavities in zirconia restorations due to its inferior microleakage prevention. Instead, composite resins and zirconia are favored, with Al₂O₃ air abrasion showing the potential to enhance marginal seal in endodontically treated teeth.</p>","PeriodicalId":12571,"journal":{"name":"General dentistry","volume":"73 1","pages":"36-43"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The W-index is based on oblique line contrast on panoramic radiographs, in which the pixel intensity of the oblique line is compared with the pixel intensity of adjacent structures at the mandibular ramus. A total of 333 patients with panoramic radiographs and pDXA results were evaluated according to T-score results and WI measurements. A Spearman correlation test was executed to assess the correlation between measures. Patients were divided into 3 groups: normal bone mineral density (BMD), osteopenia, or osteoporosis. The WI values were compared with the Kruskal-Wallis test. A significant but negligible correlation was found between the pDXA and WI results for all peripheral sites assessed. Statistically significant differences in the WI results emerged between patients with normal BMD and osteoporosis (P = 0.007) as well as between those with osteopenia and osteoporosis (P = 0.010). There were no significant differences in WI between patients with normal BMD and osteopenia (P = 0.598).
