(MDPI, 2021-08-27) Castillo Pardo de Vera, José Luis del; Navarro Cuéllar, Carlos; Navarro Cuéllar, Ignacio; Cebrián Carretero, José Luis; Bacián Martínez, Sandra; García-Hidalgo Alonso, María Isabel; Sánchez Pérez, Arturo Joaquín; Zamorano-León, Jose J.; López-Farré, Antonio J.; Navarro Vila, Carlos; Dermatología, Estomatología, Radiología y Medicina Física; Facultad de Medicina
Microsurgical scalp reconstruction is indicated in patients with large scalp defects. The aim of this study was to compare the outcomes of scalp reconstruction in oncologic patients reconstructed with latissimus dorsi (LD), anterolateral thigh (ALT), and omental (OM) free flaps. Thirty oncologic patients underwent scalp reconstruction with LD (10), ALT (11), and OM (9) flaps. The length of the vascular pedicle, the operation time, the possibility of a two-team approach, the length of hospital stays, the complications, and the aesthetic results were evaluated. The OM flap was the flap with the shortest vascular pedicle length with a mean of 6.26 ± 0.16 cm, compared to the LD flap, which was 12.34 ± 0.55 cm and the ALT flap with 13.20 ± 0.26 cm (p < 0.05). The average time of surgery was 6.6 ± 0.14 h in patients reconstructed with OM, compared to the LD flap, which was 8.91 ± 0.32 h and the ALT flap with 7.53 ± 0.22 h (p < 0.05). A two-team approach was performed in all patients for OM flaps and ALT flaps, but only in two patients reconstructed with the LD flap (p < 0.001). In patients reconstructed with the OM flap, a very satisfactory or satisfactory result was reported in seven patients (77.8%). Eight patients reported a very unsatisfactory or unsatisfactory result with LD flap (80%) and 10 patients with ALT flap (90.9%) (p = 0.002). The mean hospital stay after surgery was not statistically significant (p > 0.05). As for complications, two patients reconstructed with OM flap, five LT flaps, and two ALT flaps developed complications, not statistically significant (p = 0.235). Omental flap, latissimus dorsi flap, and anterolateral thigh flap fulfill most of the characteristics for complex scalp reconstruction. The decision on which flap to use should be based on clinical aspects of the patients taking into account that the three flaps show similar rates of complications and length of hospital stay. Regarding the aesthetic outcome, OM flap or LD flap should be considered for reconstruction of extensive scalp defects.

An adverse effect of Ocrelizumab treatment in a patient with multiple sclerosis: a case report of necrotizing periodontitis
(Gavin Publishers, 2023-04-04) Montoya Carralero, José María; Sánchez Pérez, Arturo Joaquín; Jornet García, Alfonso Felipe; Moya Villaescusa, María José; Dermatología, Estomatología, Radiología y Medicina Física
Multiple Sclerosis (MS) and Necrotizing Periodontitis (NP) are two diseases whose aetiologies and pathophysiologies do not appear to have a common link; however, treating MS with monoclonal antibodies and the decrease in humoral immunity that this entails can be a trigger or an aggravation in patients who present with quiescent NP. We describe a clinical case of NP, including clinical manifestations, treatment, and evolution during therapy with ocrelizumab and to review risk factors. A rapid progression of NP was evidenced. During the patient’s evolution, she suffered bilateral pneumonia due to coronavirus disease 2019, requiring treatment with corticosteroids and antibiotics, which led to clinical relief of her NP. Based on this case, we believe that regulated dental monitoring of patients with MS before, during, and after the administration of monoclonal antibodies may help prevent periodontal deterioration.

Influence of age and sex on platelet count: implications for optimizing growth factor-rich plasma preparation
(Medicina Oral, 2025-07-22) Sánchez Pérez, Arturo Joaquín; Palma Sánchez, Ana; Jornet García, Alfonso Felipe; Moya Villaescusa, María José; Montoya Carralero, José María; Dermatología, Estomatología, Radiología y Medicina Física
Background: Growth factor-rich plasma (GFRP) is a biomedical procedure used to promote tissue regeneration. Platelet-rich plasma (PRP) contains higher-than-average platelet concentrations and includes platelet-derived growth factors. As an autologous blood derivative, it is widely used to enhance healing and tissue regeneration . In dentistry, GFRP accelerates soft tissue healing and bone regeneration in procedures such as complex extractions, bone grafts, cyst treatments, and to improve dental implant osseointegration. Objective: To assess the potential influence of age and sex on platelet count, with the aim of optimizing the standardization of therapies involving growth factors. Material and Methods: A cross-sectional, observational, and comparative study was conducted, including a total of 384 patients. Participants were stratified into six groups based on age. From their medical records, the platelet counts obtained from analyses meeting the established inclusion criteria were recorded. Subsequently, the distribution of platelet levels was analyzed according to age groups and sex. Additionally, the potential correlation between platelet count and age was evaluated. Results: The mean platelet count was higher in women (260.9 ± 65.9 x10³/μL) than in men (250.4 ± 62.0 x10³/μL), although the difference was not statistically significant (p = 0.113). A statistically significant negative correlation was found between age and platelet count (r = -0.175; p < 0.01), indicating that platelet count decreases with age, although the correlation coefficient was low. Conclusions: Platelet count varies across the population; therefore, blood extraction for PRP preparation should be adjusted based on age group and sex.

Influence of the number of microthreads on marginal bone loss: a five-year retrospective clinical study in humans
(MDPI, 2023-03-20) Jornet García, Alfonso Felipe; Sánchez Pérez, Arturo Joaquín; Planes Nicolás, Pablo; Montoya Carralero, José María; Moya Villaescusa, María José; Dermatología, Estomatología, Radiología y Medicina Física
The purpose of the present study was to evaluate the clinical and radiographic outcomes of the number of microthreads on marginal bone over 5 years. Thirty-two implants were placed in 32 patients with partially edentulous maxillae or mandibles. Two implants with the same characteristics were placed: the first one had a 1 mm crest module and 3 microthreads (Q); and the second one had a 3 mm crest module and nine microthreads (S). The prosthesis was inserted 3 months after implant placement. Clinical and radiographic examinations were performed at the one-week, one-month, and three-month follow-up visits and then every six months until a five-year follow-up period was completed. After 5 years of follow-up, five patients withdrew from the study. Complete data were available for 27 implants, with a 100% implant survival rate. No cases of peri-implantitis were diagnosed. The average bone loss was 0.65 mm (C.I. 0.21–1.09) for Q implants and 0.86 mm (C.I. 0.39–1.33) for S implants, with no statistically significant difference. The bone level does not vary between implants with three and nine microthreads or with a 1 mm and 3 mm crest module. No differences in clinical parameters were found.

Effect of photofunctionalization with 6 W or 85 W UVC on the degree of wettability of RBM titanium in relation to the irradiation time
(MDPI, 2021-06-11) Sánchez Pérez, Arturo Joaquín; Cano-Millá, Nuria; Moya Villaescusa, María José; Montoya Carralero, José María; Navarro Cuellar, Carlos; Dermatología, Estomatología, Radiología y Medicina Física
Photoactivation with ultraviolet C light can reverse the effects derived from biological ageing by restoring a hydrophilic surface. Ten titanium discs were randomly divided into three groups: a control group, a 6 W group, and an 85 W group. A drop of double-distilled, deionized, and sterile 10 µL water was applied to each of the discs. Each disc was immediately photographed in a standardized and perpendicular manner. Measurements were taken based on the irradiation time (15, 30, 60, and 120 min). UVC irradiation improved the control values in both groups. There was no difference in its effect between the 6 W group and the other groups during the first 30 min. However, after 60 min and up to 120 min, 85 W had a significantly stronger effect. The contact angles with the 85 W ultraviolet light source at 60 and 120 min were 19.43° and 31.41°, respectively, whereas the contact angles for the 6 W UVC source were 73.8° and 61.45°. Power proved to be the most important factor, and the best hydrophilicity result was obtained with a power of 85 W for 60 min at a wavelength of 254 nm.

Effects of ultraviolet photoactivation on osseointegration of commercial pure titanium dental implant after 8 weeks in a rabbit model
(American Academy of Implant Dentistry, 2020-06-01) Sánchez Pérez, Arturo Joaquín; Cachazo-Jiménez, Carlos; Sánchez-Matás, Carmen; Martín-de-llano, José Javier; Davis, Scott; Carda-Batalla, Carmen; Dermatología, Estomatología, Radiología y Medicina Física; Facultad de Medicina
This study investigated whether a 6-Watt ultraviolet C-lamp was capable of producing photofunctionalization on commercial implants during a medium observation term of 8 weeks. A total of 20 implants were inserted in 5 New Zealand rabbits, with each animal receiving 2 implants per tibia (one photofunctionalized and one untreated), according to a previously established randomization sequence. All implants were inserted by a single surgeon following the manufacturer's instructions. Histological analysis was performed by an evaluator who was blinded to the treatment condition. After 8 weeks of healing, the 2 groups showed no statistically significant differences in terms of bone-to-implant contact. Compared to control implants, the photofunctionalized implants showed improved wettability and more homogenous results. Within the limits of the present study, the use of this 6-W ultraviolet C-lamp, for an irradiation time of 15 minutes at a distance of 15 cm, did not improve the percentages of bone-to-implant contact in rabbits at an osseointegration time of 8 weeks.

La utilizacion de pilares transmucosos definitivos de colocación inmediata
(2020) Nicolás Silvente, Ana Isabel; Rivas Perez, A.; Garcia Lopez, R.; Alemán-Marín, J.; Chiva García, Fernando; Sánchez Pérez, Arturo Joaquín; Dermatología, Estomatología, Radiología y Medicina Física
El uso de pilares de cicatrización transmucosos previos a la colocación del,pilar protésico definitivo es una técnica que se ha desarrollado durante muchos años en la implantología clásica. La desconexión y conexión de forma repetida de estos pilares o aditamentos dan lugar a una respuesta ósea negativa que se manifiesta en forma de pérdida de hueso a nivel de la cresta marginal, acompañada por una migración apical de tejidos blandos. Este artículo pretende realizar una revisión de la literatura del estado actual del uso de los pilares transmucosos definitivos con colocación inmediata el día de la inserción de los implantes y el mantenimiento del sellado biológico, minimizando la pérdida ósea periimplantaria y remodelando de forma adecuada los tejidos blandos adyacentes, frente al protocolo tradicional del uso de aditamentos que se desconectan en multiples ocasiones produciendo pérdida ósea periimplantaria. La evidencia científica sugiere que los mejores resultados biológicos, estéticos y funcionales se consiguen con el uso del pilar definitivo colocado de forma inmediata a la inserción del implante, especialmente en implantes colocados de forma yuxtacrestal y en implantes postextracción.
