[more ▼] The completely edentulous maxilla can be considered as a real handicap for many patients. Implantology has revolutionized and transformed the lives of these patients. To achieve a proper result, an implant treatment plan must be defined corresponding to the clinical situation. To determine the best choice of implant-prosthetic rehabilitation, the decision making will be guided by three elements. Firstly, the available space for prosthetic rehabilitation will be determined in the pre-implant prosthetic study which is an absolutely essential step. It is, indeed, the prosthesis which guides the surgery and not the opposite.Asecond element is the long-term success rate of implant rehabilitations.Are certain rehabilitations superior to others on this subject? Finally the third element is the patient satisfaction at the end of the treatment. It is an essential element as it is the ultimate goal of the treatments.

[more ▼] The capacity of photo-sensitizers, used in combination with laser light to kill micro-organisms has been demonstrated in different studies. Photo-activated disinfection (PAD) has been introduced in periodontology as an aid for disinfection of periodontal pockets. The aim of this study is to verify the harm for dental vitality of the use of PAD in periodontal pockets. Root canals of 24 freshly extracted human teeth where prepared using profiles up to a size of ISO #50 and filled with thermo-conductor paste. A silicon-based false gum was made in which a periodontal pocket was created and filled with photo-sensitizer phenothiazine chloride (phenothiazine-5-ium, 3.7-bis (dimethylamino)-, chloride). The external root surface was irradiated during 60 s with a 660-nm diode laser (output power: 20 mW; power density: 0.090 W/cm(2); Energy density: 5.46 J/cm(2)) using a periodontal tip with a diameter of 1 mm and a length of 7 mm. Temperatures were recorded inside the root canal using a thermocouple. Measurements were recorded every second, starting at 10 s before lasering, during the irradiation and were continued for 150 s after the end of irradiation, and six measurements were done per tooth. An average temperature increase of 0.48 +/- 0.11 degrees C was recorded. Our results demonstrated that pulp temperature increase was lower than 3 degrees C, which is considered to be harmless for pulp injury. Regarding pulp temperature increase, the use of PAD for disinfection of periodontal pockets can be considered as a safe procedure for dental vitality.

[more ▼] Photo-activated decontamination (PAD) has been reported in caries treatment as an aid in dentine decontamination. The aim of this study is to verify the harmlessness for pulp vitality of photo-activated decontamination (PAD) in caries treatment. Twenty freshly extracted single-rooted teeth were used. Deep class I cavities with a </= 0.5 mm dentine thickness between the floor of the cavity and the roof of cameral pulp were prepared. Following the manufacturer's instructions, cavities were filled with a photo-sensitizer (Phenothiazinechloride: 10 mg /ml), irradiated during 30 s with a 660-nm diode laser (output power: 40 mW in continuous wave; total delivered energy density: 4.87 J/cm(2)). Pulp temperature raises were recorded using a thermocouple (ALCr). Measurements were recorded every second during the irradiation and 150 s afterwards. Six records were repeated for each tooth. After 30 s of irradiation, the mean of temperature rise was 0.83 degrees C +/- 0.22 degrees C. All records showed temperature increases lower than the 3 degrees C (safety level for pulp injury). Based on our in vitro study, we can conclude that the dental pulp temperature rise following the use of PAD technique for the decontamination of dentine can be considered as save procedure for pulp vitality.

[more ▼] The aim of this study was to determine whether it is safe to use photo-activated disinfection (PAD) during root canal treatment without heating the periodontal tissues. Root canals of 30 freshly extracted single-rooted teeth were prepared using ProFiles up to size ISO 40 and then filled with photo-sensitiser: tolonium blue (1.2 mg/l). The 635 nm diode laser was used with the manufacturer's endo-tip. Samples were irradiated for 150 s (output power 100 mW, approximate energy density 106.16 J/cm(2)). Temperatures were recorded at working length on the external root surface. After 150 s of PAD irradiation, the average temperature rise was 0.16 +/- 0.08 degrees C. All values were lower than the 7 degrees C safety level for periodontal injury. It was concluded that, regarding the temperature increase, the use of PAD in root canals could be considered harmless for periodontal tissues.

[more ▼] In this study, we compared the microleakage of composite fillings cured with halogen bulb, LED and argon ion laser (488 nm). Twenty-four extracted human molars were divided randomly in three groups. Six cavities were prepared on the coronal part of each tooth. Standard cavities (1.7 x 2 mm) were prepared. Cavities were acid etched, sealed with Scotch Bond 1 and filled by a hybrid composite. Cavities were exposed to one light source, thermocycled and immersed in a 2% methylene blue dye solution. Dye penetration in the leakage of cavities was recorded using a digital optical microscope. Mean values of percentage of dye penetrations in microleakages of cavities were 49.303 +/- 5.178% for cavities cured with LED, 44.486 +/- 6.075% with halogen bulb and 36.647 +/- 5.936% for those cured by argon laser. Statistically significant difference exists between cavities cured by halogen vs LED (P < 0.01), halogen vs laser (P < 0.001) and LED vs laser (P < 0.001). The lowest microleakage was observed in the cavities and composites cured with argon ion laser.

[more ▼] The global impression technique allows to obtain in a single stage the impression of the abutment as well as their neighboring teeth. This technique often requires the placement of one or two retraction cords in the sulcus. The impression technique herein described is the double mix method. This method is based on the use of two elastomers with different viscosities, but from the same group thus allowing a simultaneous polymerization.

[more ▼] OBJECTIVES: To evaluate, in an elderly population, whether poor oral status might be a contributing factor to the development of undernutrition and might be associated with less eating pleasure, more subjective eating difficulty and increased mashed food consumption. METHODS: An oral examination and an evaluation of masticatory capacity were performed on 120 institutionalized elderly subjects. The nutritional assessment included serum albumin concentration, the Mini Nutritional Assessment and a questionnaire on eating habits. RESULTS: Edentulous subjects without dentures or with only one complete denture had significantly lower MNA scores than edentulous subjects with two complete dentures (p < 0.05). Edentulous subjects with two complete dentures more frequently reported taking pleasure from eating (p = 0.05), and had less frequent difficulties with hard foods (p = 0.01) than edentulous subjects without dentures or with only one complete denture. Mashed food consumption (p < 0.01) was also reported more frequently in edentulous subjects without dentures or with only one complete denture. Subjects with two complete dentures had similar or better MNA scores as dentate subjects with relatively few remaining teeth (10.4 +/- 7.8 teeth). About half of the subjects (53%) could not perform the masticatory test. These subjects had lower MNA scores (p = 0.001) and a larger proportion ate mashed food (p < 0.001) compared to those who were able to perform the test. CONCLUSIONS: Poor oral status (edentulous without dentures or with only one complete denture) increased difficulty in eating hard foods, increased mashed food consumption and decreased eating pleasure. It seemed also to put institutionalized subjects at higher risk of undernutrition.

[more ▼] Demographic projections show an important increase of the elderly population. The percentage of complete edentulous elderly patients is decreasing but their total number will remain constant. The prevalence of caries (essentially root caries) and of periodontal disease is, actually, very important. The increase of remaining teeth in the aging population, is a risk for a higher prevalence of these problems. It's time to become aware of this situation and to develop prevention and adapted treatments for this population.
