Nahass, H. E. L., and S. N. Nabil, Analysis of the dimensions of the labial bone wall in the anterior maxilla: a cone-beam computed tomography study, , In Press. Abstract

Immediate implant placement in extraction socket does not appear to prevent the resorption of the labial wall. It has been recommended that a minimal thickness of 1–2 mm of buccal bone should be available to preclude the resorption of the facial vertical dimension of the socket wall.

The aim was to determine the dimension of the facial buccal plate of bone in the anterior esthetic zone at different levels and relate it to immediate implant placement.

Materials and methods
Seventy-three patients' cone-beam tomographic scans were included in the study (42 female and 31 male, mean age 39.6 years). The images were acquired using OnDemand software. The measurements taken included:

Distance between the CEJ and the alveolar crest.
The labial bone thickness at different levels in relation to alveolar crest: at 1, 2, and 4 mm
The results
The measurements demonstrated that the distance between the CEJ and the crest was 2.10 ± 0.85 for the central and 2.09 ± 0.72 for the lateral incisor. The measurement taken at M0 (crestal level) revealed that only 1% of the incisors showed a thick labial bone (1–2 mm) and 73% showed a thin bony wall (0.5–1 mm) and 25% showed very thin wall <0.5 mm. At the M1, 7% showed very thin bony wall and 86% showed a thin bony wall while only 6% exhibited a thick bony wall. The M2 showed only 1% of very thin bony wall, and about 85% showed a thin bony wall and 14% exhibited a thick bony level. The M4 demonstrated very thin bony wall and about 75% thin bony wall and 23% showed thick bony wall. Males showed statistically significantly higher mean distance between cemento–enamel junction and alveolar crest (CEJ-AC) than females at the central as well as lateral incisors. To obtain good results, meticulous preoperative analysis is recommended. Thus, to chose an adequate treatment approach, the utilization of CBCT is recommended.

Aim: The aim of the current study was to evaluate the effect of finishing and polishing and an in-office bleaching gel on the surface roughness of single-shade (Omnichroma) and group-shade (Estelite Alpha) resin composites.Methodology: A total of ten composite disc-shaped specimens; five specimens for each material were prepared using Teflon mold (1-mm thick and 8-mm diameter). The resin composites were cured against mylar strips to produce flat smooth surface of the tested specimens. Then each disk was finished and polished using multi-step finishing and polishing system (Astropol, Ivoclar Vivadent). Each specimen was bleached using an in-office bleaching system two times in a row using 38% hydrogen peroxide (H2O2). The average surface roughness (Ra, in μm) of the specimens was measured using non-contact optical profilometry at baseline, after finishing and polishing, and after bleaching procedure. Intergroup comparison was performed using independent t-test, while intragroup comparison was performed using one-way ANOVA followed by Tukey post-hoc.Results: Comparison between both materials has revealed statistically significant difference at baseline (P = 0.0086), with Estelite Alpha showing higher surface roughness. However, after polishing and bleaching there was no statistically significant difference between both materials (P = 0.5796 and P = 0.3010) respectively. Conclusion: The surface roughness of resin composites is material dependent. Omnichroma demonstrated lower initial Ra value than Estelite Alpha. However, Omnichroma showed significant increase in surface roughness following finishing and polishing, unlike Estelite Alpha. Bleaching with 38% H2O2 showed no effect on the surface roughness of both materials.

PURPOSE: Leukocyte adhesion deficiency (LAD) represents a rare group of inherited inborn errors of immunity (IEI) characterized by bacterial infections, delayed umbilical stump separation, and autoimmunity. This single-center study aimed at describing the clinical, immunological, and molecular characterizations of 34 LAD-I Egyptian pediatric patients.

METHODS: Details of 34 patients' personal medical history, clinical and laboratory findings were recorded; Genetic material from 28 patients was studied. Mutational analysis was done by Sanger sequencing.

RESULTS: Omphalitis, skin and soft tissue infections with poorly healing ulcers, delayed falling of the umbilical stump, and recurrent or un-resolving pneumonia were the most common presentations, followed by chronic otitis media, enteropathy, periodontitis; and recurrent oral thrush. Persistent leukocytosis and neutrophilia were reported in all patients, as well as CD18 and CD11b deficiency. CD18 expression was < 2% in around 90% of patients. Sixteen different pathological gene variants were detected in 28 patients who underwent ITGß2 gene sequencing, of those, ten were novel and six were previously reported. Three families received a prenatal diagnosis. Patients were on antimicrobials according to culture's results whenever available, and on prophylactic Trimethoprim-Sulfamethoxazole 5 mg/kg once daily, with regular clinical follow up. Hematopoietic stem cell transplantation (HSCT) was offered for 4 patients. However due to severity of the disease and delay in diagnosis, 58% of the patients passed away in the first 2 years of life.

CONCLUSION: This study highlights the importance of early diagnosis and distribution of ITGß2 gene mutation in Egyptian children. Further molecular studies, however, remain a challenging necessity for better disease characterization in the region.
