Influence of dental treatment in place on quality of life in oral cancer patients undergoing chemoradiotherapy

BACKGROUND: This study aims to assess, in the population of patients with oral cancer treatment, the influence on the quality of life of two protocols of dental treatment: not ruled hospital treatment versus ruled hospital treatment. Matrial and METHODS: A quasi-experimental approach justified on ethical grounds was used. A total of 41 patients were included in the control group (not ruled treatment outpatient health center) and 40 in the experimental group (ruled hospital treatment). A total of 14 questions to both groups were conducted in three stages: before starting cancer treatment, during treatment and after treatment. the proportions of positive responses in groups and different times were compared using the chi-square test. RESULTS: Based on similar situations during cancer treatment were identified as six issues favorable to the experimental group difference. This number rose to nine after finishing oncological treatment. CONCLUSIONS: From our data we can confirm that planned dental treatment performed during the oral cancer treatment produces an improvement in the quality of life in patients with oral cancer

Relationship Between Osteoporosis and Marginal Bone Loss in Osseointegrated Implants: A 2-Year Retrospective Study.

BACKGROUND: Fitting implants in osteoporotic patients has traditionally been controversial, and there is little scientific evidence relating osteoporosis to marginal bone loss (MBL). The aims of this study are as follows: 1) to evaluate the possibility of a correlation between osteoporosis, as measured by the mandibular cortical index (MCI), and MBL and 2) to assess how various systemic diseases, periodontitis, and placement of implants in regenerated bone are correlated with MBL and MCI. METHODS: This retrospective study examines 212 implants inserted in 67 patients. To take a possible cluster failure into account, an implant for each patient was selected (n = 67 implants). MBL was assessed. Osteoporosis was evaluated using the MCI. Both MBL and MCI were assessed from panoramic radiographs. χ(2) test was performed (Haberman post hoc test). Significance was P <0.05. RESULTS: When the total sample implant (N = 212) was evaluated, a significant association was found between the presence of osteoporosis and MCI (P <0.001) and between the presence of diabetes mellitus and MCI (P <0.01). Significant associations were also found between MBL and placement of implants in regenerated sites (P <0.001) and between MBL and a previous history of periodontitis (P <0.05). When the sample is evaluated only in selected implants (one per patient, n = 67), significant differences appear to relate only to the MBL with the placement of implants in regenerated bone sites (P <0.001). CONCLUSIONS: Osteoporosis (as evaluated by MCI) does not pose a risk for the development of greater MBL. Parameters adversely affecting the development of increased MBL are a previous history of periodontitis and especially the placement of implants at sites of bone regeneration.

Importance of Poly(lactic-co-glycolic acid) in Scaffolds for Guided Bone Regeneration: A Focused Review.

Total or partial tissue damage and loss of function in an organ are two of the most serious and costly issues in human health. Initially, these problems were approached through organ and allogenic tissue transplantation, but this option is limited by the scarce availability of donors. In this manner, new bone for restoring or replacing lost and damaged bone tissue is an important health and socioeconomic necessity. Tissue engineering has been used as a strategy during the 21st century for mitigating this need through the development of guided bone regeneration scaffold and composites. In this manner, compared with other traditional methods, bone tissue engineering offers a new and interesting approach to bone repair. The poly-α-hydroxy acids, which include the copolymers of lactic acid and glycolic acid, have been used commonly in the fabrication of these scaffolds. The objective of our article was to review the characteristics and functions of scaffold with biomedical applications, with special interest in scaffold construction using poly(lactic-co-glycolic acid) polymers, in order to update the current methods used for fabrication and to improve the quality of these scaffolds, integrating this information into the context of advancements made in tissue engineering based on these structures. In the future, research into bone regeneration should be oriented toward a fruitful exchange between disciplines involved in tissue engineering, which is coming very close to filling the gaps in our ability to provide implants and restoration of functionality in bone tissue. Overcoming this challenge will provide benefits to a major portion of the population and facilitate substantial improvements to quality of life.

Alveolitis seca. Actualización de conceptos / Update on dry socket: A review of the literature

La alveolitis seca es una complicación postoperatoria que acontece tras la extracción dental, quedando definida como una inflamación del alveolo. En el caso que esta inflamación sobrepase las paredes alveolares, estaríamos ante una osteítis localizada. La frecuencia de aparición de la alveolitis se ha referido en un margen muy amplio, desde el 1 % hasta el 70 %. Generalmentese acepta que la mayor incidencia de alveolitis acontece tras la extracción de terceros molares retenidos, en los que la aparición de esta complicación se tasa en un 20-30 % de las extracciones,diez veces más que en el resto de extracciones dentales. En el presente artículo se revisan la forma de aparición clínica,los factores de riesgo relacionados con el cuadro y las teorías etiopatogénicas que intentan explicar su aparición. También se examinan las pautas utilizadas actualmente en su tratamiento. Acorde con las teorías patogénicas de la alveolitis seca, para su prevención se han estudiado agentes fibrinolíticos, lavados, antisépticos y antibióticos. Analizamos los distintos fármacos utilizados, criticando los resultados obtenidos. Como conclusión, y a partir de los datos revisados, pensamos, sin abandonar el territorio de la hipótesis, que es posible defender un modelo patogénico en el que los mecanismos fibrinolíticos bacterianos y del propio organismo colaboren para producir la alveolitis seca

Dry socket is a postoperative complication that occurs after adental extraction and has been defined as an inflammation of the alveolus. If this inflammation should surpass the alveolar walls, it would result in a located osteitis. The frequency of appearance of dry socket has been reported in a very wide margin, from 1%until 70%. It is generally accepted that most dry sockets appear after extraction of third retained molars, in which the occurrence of this complication is about 20-30% of dental extractions, ten times more than in the rest of dental extractions. In this work we review the forms of clinical appearance, the riskfactors related to this affection and the etiopathogenic theories that try to explain its appearance. The treatment management is also examined. Fibrinolitic agents, laundries, antiseptic, and antibiotics have been studied for its prevention, according to the pathogenic theories of dry socket. We analyze and critize the different drugs and their results. In conclusion from the revised data, we think it is possible to defend a pathogenic model in which the bacterial fibrinolytic mechanisms and the microorganism of the own patient may contribute to produce the dry socket
