Endodontic therapy is essentially a debridement procedure that requires the removal of the irritants of the canal and periapical tissue if success is to be gained. The debridement may include instrumentation of the canal, placement of medicament and irrigants. Complete cleaning of the root-canal system requires the use of irrigants that dissolve organic and inorganic material. The study aimed to evaluate changes in dentin microhardness after canal irrigation with different solutions. Twenty four freshly extracted human mandibular molars (distal roots with single canals) were used. 10mm root length was taken as standard length. The roots were embedded into auto polymerizing acrylic resin using plastic molds before the canals preparation and micro hardness test. The distal roots were prepared with one shape rotary file. Before the preparation each root was irrigated with 1ml distilled water. Then the roots were divided into four groups according to the final irrigation protocol: Group A: NaOCl 2.5%, Group B: EDTA 17%, Group C: Citric Acid 40%, Group D: Distilled Water. For (Vicker microhardness test) the same load and time 500 g test load for 20 seconds, will be conducted three times at distance 0.5mm from canal lumen ; thus there will be 9 indentations on each specimen surface. An average of the three readings for each test condition will be recorded as the VHN value of a specimen. Comparing all four groups statistically there was no significant difference among them. The mean values were found more reduced in EDTA group followed by NaOCL group, and then Control and Citric Acid groups. All the groups showed reduction in dentin microhardness. EDTA group showed the maximum reduction followed by NaOCL group, and least with Citric Acid group.

Abstract We developed a simple and highly sensitive RIA for glycated protein (GP), and used it to measure GP in serum and urine from 15 normal controls and 30 diabetics (14 with urinary excretion rate of albumin, Ualb less than 15 micrograms/min, group A; nine with 15 less than or equal to Ualb less than or equal to 150 micrograms/min, group B; and seven with Ualb greater than 150 micrograms/min, group C). The mean serum concentration of GP was above normal in all groups of diabetics, and the mean glycation ratios of serum protein (SGP) were higher in groups B and C than in normal subjects. Urinary concentrations of GP also were increased in groups B and C, although the glycation ratio of urinary protein (UGP) was decreased in group C. Consequently, the selectivity of urinary excretion of GP (UGP/SGP) was significantly decreased in group C. Moreover, there was a significant difference in the mean values of selectivity between groups of patients with various degrees of retinopathy. We suggest that measurements of serum and urinary GP are useful to evaluate the progression of diabetic complications.

Masticatory performance is directly correlated with masticatory muscle work to grind and cut the food. Chewing efficacy is decisive to eating a variety of foods needed maintain general health status at all ages. Older people have oral problems that get worse with age. Elders have more pathologies such as periodontal diseases, caries, tooth loss and inadequate dental prostheses than younger subjects. Objectives: to investigate the correlation between masticatory bite force (MBF) and body mass index (BMI) vs. aging and sex. Methods: This study was performed on 426 subjects (213 females plus 213 male) assigned into five different groups by age. Group “A” aged from 20 to 35 years; group “B” aged 45–59 years; group “C” aged 60–69 years; group “D” aged 70–79 years; and group “E” aged more than 79 years. Results: There were not statistically significant differences in right-side MBF versus left-side MBF. The differences between sex were statistically significant with a stronger bite in males than females (p < 0.05). At the same time, younger subjects had a stronger bite than elders (p < 0.05). In group “E”, more corpulent subjects (BMI > 25) had an MBF higher than less corpulent subjects (BMI < 25, p < 0.05). The analysis of mean MBF showed a statistically significant difference within all groups stratified by BMI with mean values inversely proportional with age (p < 0.001). Conclusion: The results in our study confirm data from many scientific papers. The importance of the present paper was to correlate data between and within a large sample with a wide range of ages. Our sample subjects had a 31%–33% decrease in MBF from group “A” to group “E” group, but they all had full permanent dentation and they preserved a valid MBF.

Epidemiological studies have shown that asthma and rhinitis often coexist in the same patients and the prevalence of asthma is greater in patients with rhinitis. The aim of this study was to evaluate the differences in bronchial reactivity in subjects with seasonal and perennial rhinitis. We enrolled 128 subjects with seasonal or perennial allergic rhinitis divided into three groups: A with perennial rhinitis and allergy to “Dermatophagoides Pteronissynus”; B with seasonal rhinitis and allergy to “Graminae” and “Parietaria”, who underwent methacholine challenge test (MCHt) during the exposure period (fron March until May); C with seasonal rhinitis and allergy to “Graminae” and “Parietaria”, who underwent MCHt during the non exposure period (from June until February). The PC20 mean values of group A (1774.8 ± 20.7) and group B (1740.7 ± 38.8) were not significantly different, but significantly lower than those of group C (3010.0 ± 56.9) (p=0.001). The subjects with group A were positive to the MCHt in 54.54%, against 29.28% of group B and 11.62% of group C (p=0.007). The results show differences in the degree of bronchial responsiveness. The dose-response curves documented a lower value of PC20 in the group with perennial rhinitis and a statistically significant difference of bronchial hyperresponsiveness prevalence between the three groups (p=0.007).

Virucidal Efficacy

Abstract Background. The oral cavity is potentially high-risk transmitter of COVID-19. Antimicrobial mouthrinses are used in many clinical pre procedural situations for prophylactic purposes. An evident-based investigation for an effective mouthwash solution against salivary SARS-CoV-2 is urgently required for the exposure reduction during dental procedures. Aims. This study aimed to evaluate in vivo virucidal efficacy of 2 mouthwashes: 1% Povidone-iodine and 0.2% Chlorhexidine as a dental preprocedural oral disinfection against salivary SARS-CoV-2. Materials and Methods. In this randomized-controlled clinical trial, studied group comprised laboratory-confirmed COVID-19 positive patients through nasopharyngeal swabs. Participants were divided into 3 groups. For 30 seconds, group A gargled with 1% Povidone-iodine, group B mouthrinsed with 0.2% Chlorhexidine and control group C mouthrinsed with distilled water. Saliva samples were collected before and 5 minutes after mouthwash. SARS-CoV-2 rRT-PCR was then performed for each sample. Evaluation of the efficacy was based on difference in Ct value. The analysis of data was carried out using GraphPad Prism version 5 for Windows. Paired t test and unpaired t test were used. A probability value of less than 0.05 was regarded as statistically significant. Results. Sixty-one compliant participants (36 female and 25 male) with a mean age 45.3 plusmn 16.7 years-old were enrolled. A significant mean Ct value difference (p < 0.0001) between the paired samples in group A (n = 25) and also in group B (n = 27) (p < 0.0001) was found. In contrast, no significant difference (p = 0.566) existed before and after the experiment in the control group C (n = 9). Moreover, a significant difference was noted between the delta Ct of distilled water wash and each of the 2 solutions 1 % Povidone-iodine (p = 0.012) and Chlorhexidine 0.2% (p = 0.0024). No significant difference was found between the delta Ct of patients using 1% Povidone-iodine and Chlorhexidine 0.2% solutions (p = 0.24). Conclusion. Chlorhexidine 0.2% and 1% Povidone-iodine oral solutions are effective preprocedural mouthwashes against salivary SARS-COV-2 in dental treatments. Their use as a preventive strategy to reduce the spread of COVID-19 during dental practice should be systematically implemented.

ABSTRACTObjectives: The aim of this study was to investigate surface roughness in provisional crown acrylics, after polishing, reinforced with different concentrations of glass fibers.Methods: A total of 48 disk-shaped specimens were prepared using autopolymerizing acrylic resin. These specimens were divided into four groups according to the level of glass fiber added: Group A (no fiber), Group B (0.5%), Group C (1%) and Group D (2%). After polishing the specimens, an average surface roughness (Ra) value was calculated using a profilometer from four randomly selected points on the surface.Results: A significant difference was determined among the surface roughness values of provisional crown resins to which different concentrations of fiber had been added (P<.001).Tukey�s test was then used to perform paired comparisons of the data between the different groups, and a significant difference was found between Group A (no fiber) and the other groups, between Group B (0.5%) and Group D (2%) and between Group C (1%) and Group D. On the other hand, there was no significant difference between Group B and Group C.Conclusions: The reinforcement of provisional crown and fixed partial denture resin with glass fibers increases surface roughness.
