ABSTRACT Retention in mandibular dentures has always been a challenge for the treating dentist. Denture adhesives are known to improve the adhesive bond between the denture and the underlying tissues. However, denture adhesives still remain unexplored and not much is known about the efficacy of these materials in mandibular dentures especially in patients with poor foundations. The present study was carried out to compare the efficacy of different commercially available denture adhesives in relation to their retentive ability in patients with good well formed mandibular ridges and in patients with resorbed and flat mandibular ridges. Seventy edentulous patients, age range between 50 to 70 years, were selected. The patients were divided into 2 groups; group 1 comprised of 35 patients with good well formed mandibular ridges and group 2 consisted of 35 patients having low well rounded mandibular ridges. The adhesion and cohesion that developed between the dentures and the underlying tissues when the various materials were interposed between them was evaluated with the help of a test apparatus in newtons. Mean value of retention in denture without adhesive was 9.93 N and 24.53 N in resorbed and well formed ridges respectively. Use of denture adhesive materials led to a higher value of retention as opposed to when the dentures were used without adhesives. This was true for patients with good well formed mandibular ridges as well as for patients with poor foundations. Among the various denture adhesive powders tested, Fittydent showed better results, i.e. 29.56 and 33.05 in resorbed and well-formed ridges respectively as opposed to fixon which showed values of 16.47 and 27.70 respectively.

The aim of this experimental study was to assess the spine development in growing rats following pinealectomy or partial sensorimotor cortical area damage. A total of 68 Wistar albino rats (Rattus norvegicus v. alba f. domestica) aged 3–4 weeks were divided into four groups. In group 1 (n = 22) pinealectomy was performed, in group 2 (n = 24) the sensorymotor cortical area 2 × 1 × 1 mm below the coronal suture was removed. Sham operation consisted of a craniotomy (n = 11) and a craniotomy with a durotomy (n = 11). All surgeries were performed from the left side. The rats were killed four months after surgery and radiography was then made. Scoliosis, C2-T7 lordosis and T7-S1 kyphosis were measured.The brains of rats after sensorimotor cortical area removal were isolated and investigated including histological examination (light microscope). Scoliosis of 9–14 degrees (mean value 10.8) was developed in five animals after pinealectomy; in rats after removal of the sensorimotor cortical area scoliosis of 10–24 degrees (mean value 15.9) was observed in eight animals. The scoliotic curves were non structural. Our results indicate the importance of cortical area damage, together with craniotomy and durotomy in the development of growing rat spine. These damages could cause a disorder of balance between smaller inhibitory and greater facilitating area of central nervous system, controlling the muscular tone and resulting in the development of increased lordosis and kyphosis and non structural scoliosis due to muscle imbalance. Thus the new hypothesis of scoliosis aetiology was introduced.

AbstractNasendoscopy is an essential tool in assessing the dynamic function and structure of the velopharyngeal sphincter during speech and swallowing.Flexible fibre-optic nasendoscopy has been used by the cleft palate team at Withington Hospital, Manchester since 1989. Seventy-six patients were referred between 1989 and 1994 for evaluation of velopharyngeal function during speech. Flexible nasendoscopic evaluation was attempted in 50 patients, and successfully carried out in 43 patients. The age range was four years to 77 years (mean 21 years). The patients were divided into two groups: Group 1 consisting of patients with cleft palate and Group 2 comprised of patients with non-overt cleft palate-related velopharyngeal dysfunction of various aetiologies; such as, submucous cleft, post-tonsillectomy, post-adenoidectomy, neurological and post-traumatic.Based on the findings on nasendoscopy, videofluoroscopy and clinical speech/voice analysis the following treatment options were recommended: 17 (40 per cent) for pharyngoplasty, five (11 per cent) for revision pharyngoplasty, 15 (35 per cent) for speech therapy, four for an obturator and one for tonsillectomy. Two previously undetected submucous clefts were diagnosed.

Abstract This study aimed to evaluate sodium hypochlorite (NaOCl), limewater (LW), and Polymyxin B (PMB) as irrigants over MMP-3, MMP-8 and MMP-9. Thirty-three patients with apical periodontitis of single-rooted teeth were treated according to three-experimental groups (n=11): group-1: 2.5% NaOCl was used as irrigant; group-2: 2.5% NaOCl for the first two files and LW: [0.14% Ca(OH)2] for the last two files; group-3: 2.5% NaOCl for the first two files and PMB for the last two files. The association of Ca(OH)2 and CHX was used as an intracanal medication in all groups. Four root canal samplings (S) were collected: S1) immediately after access cavity; S2) after biomechanical preparation; S3) after EDTA application; and S4) after removal of the intracanal medication. After quantification of MMP-3, MMP-8, and MMP-9, the data were analyzed by Friedman and Kruskal-Wallis tests and completed by Dunn test (5%). Regardless the used irrigant, there was no difference in reducing MMP-3 or MMP-8 (P=0,5273, P=0,7048 respectively). However, in reducing MMP-9 (P=0,0246) the NaOCl group was the most effective followed by NaOCl+LW group and NaOCl+PMB group respectively. The intracanal medication [Ca(OH)2 + CHX] with the NaOCl and NaOCl+LW was effective in reducing MMP-8 (P<0,0001, P=0,0025) and MMP-9 (P=0,0007, P=0,0047) respectively, but not for the group of NaOCl+PMB which was not effective in reducing MMP-8 or MMP-9 (P=0,1718, P=0,1953) respectively. NaOCl and NaOCl+LW were effective in reducing MMP-9 levels, and this effectivity could be improved by the use of the intracanal medication [Ca(OH)2 + CHX] in reducing MMP-8 and MMP-9 levels.

Background: The pain and limitation of shoulder function can disrupt daily activities of patients for months to years. Adhesive capsulitis is considered a self-limiting disease but the duration remains uncertain. The brunt of the disease is focussed on the inflamed joint capsule. On this basis, use of corticosteroid injection is justified. However, injection method is not conclusive. Objectives: To compare clinical benefits of intra-articular injection alone versus combined intra-articular and subacromial injections in management of adhesive capsulitis. Methods: Fifty-nine patients with diagnostic criteria for adhesive capsulitis were included in the study from March 2019 to September 2020. Patients were divided into two groups; patients who underwent intra-articular (IA) injection alone (Group 1) and those who received both intra-articular and sub-acromial (IA+SA) injection (Group 2). The injections were landmark guided. Patients were followed up at three, six, and 12 weeks. Pain was recorded using visual analogue scale (VAS) and subjective function using Constant-Murley score. Results: Twenty-eight patients were included in Group 1 (IA) and 31 in Group 2 (IA+SA). Thirty-six patients were female (18 each in Group 1 and Group 2) and 23 patients were male (Group 1 = 13; Group 2 = 10). In the twelfth week, VAS score was reduced in both the groups. On comparing the mean value of Constant-Murley score between the two groups there is significant difference in value recorded at the sixth and twelfth week. Conclusion: The IA+SA injection provides significant reduction in pain and better function in the short term over the IA injection.

ABSTRACT A Clinico-Radiological Study was conducted to establish a set relation between crest of residual alveolar ridge and neutral zone so that a uniform pattern could be followed for teeth setting. Thirty healthy edentulous patients with class – I ridge relation and who had not undergone any major oral surgical procedure was included in this study. Patients were divided into two groups, 1, who were edentulous from six months to two year and group 2, who were edentulous from two or more years. Fifteen patients were in each group. Results showed that in group 1 patients, neutral zone lied lingual to or on crest of alveolar ridge and in group 2 patients, neutral zone shifted to buccal side. Therefore, by studying the pattern of shift of neutral zone to buccal side we should come out with a reasonable plan for placing our teeth looking at duration of edentulousness.

Objectives: This study aimed to assess the microleakage of Pedo Jacket crowns compared to stainless steel crowns (SSCs) cemented with different luting cements. Materials and Methods: In this in-vitro experimental study, 80 primary molars were randomly divided into four groups of 20 each. Groups 1 and 2 were subjected to standard tooth preparation for SSC. Crowns in group 1 were cemented with glass ionomer (GI), and crowns in group 2 were cemented with a resin-modified glass ionomer (RMGI) cement. In groups 3 and 4, minimal tooth preparation was performed for Pedo Jacket crowns, and the crowns were cemented with RMGI and Panavia resin cement, respectively. Microleakage was measured at mesial and distal surfaces in micrometers (µm), and the mean value for each tooth was calculated. One-way analysis of variance (ANOVA) was applied to compare the microleakage of the four groups. Results: Group 3 (Pedo Jacket cemented with RMGI) showed the highest microleakage (1523.83±250.32 µm) with significant differences with the remaining three groups (P<0.001). Microleakage in group 4 (Pedo Jacket cemented with Panavia) was significantly lower than that in the other three groups (301.25±219.53 µm, P<0.001). Groups 1 (SSCs cemented with GI) and 2 (SSCs cemented with RMGI) were not significantly different in terms of microleakage (P=0.49) although group 1 showed slightly higher microleakage than group 2 (598.43±260.85 µm versus 500.25±124.74 µm). Conclusions: Pedo Jacket crowns can serve as an acceptable esthetic alternative to SSCs if cemented with resin cements.

Aim. To study the effect of reformation of the anterior chamber by air or by a balanced salt solution, after smooth phacoemulsification on the corneal endothelial count and morphology. Methods. A prospective interventional nonrandomized comparative study included 500 eyes of 500 patients with age range between 50 and 60 years, prepared for cataract surgery and presented to the Ophthalmology department of Sohag University Hospital in the period from October 2016 to May 2017. Corneal endothelial morphology and count were examined, and the results were recorded for all cases before the surgery. Patients were divided into two groups, and both groups were diagnosed with grade 2 cataract and underwent uncomplicated phacoemulsification performed by well-trained surgeons. At the end of the surgery, group 1 was subjected to a reformation of the anterior chamber via a balanced salt solution (BSS) injection while group 2 was subjected to a reformation of the anterior chamber via air injection. Corneal endothelial morphology and count were evaluated in the first and 3rd month postoperatively. Results. The study included 500 patients (250 in each group), 220 males (44%) and 280 females (56%) with no significant statistical age differences. Both preoperative and postoperative (3 months after the operation) recorded parameters of the corneal endothelium did not show any significant statistical differences. The cumulative dissipated energy was recorded, for all cases of both groups, during phacoemulsification with no significant statistical differences (P=0.7). Conclusion. There is no difference between the effect of reformation of the anterior chamber after phacoemulsification, using air or using a BSS injection, on the corneal endothelial count and morphology.

Background: The purpose of this study is to evaluate the effect of an electromyography-guided adjustment of an occlusal appliance on the management of Temporomandibular disorder-related pain. Methods: Data from 40 adult patients (20 males and 20 females), who underwent treatment with occlusal appliances, were recorded. A total of 20 appliances were adjusted according to electromyographic data (group 1), while the others were adjusted by a clinical conventional procedure (group 2). Muscle pain to palpation, pain during articular movements and headache were recorded by a VAS score (from 0 to 100) before the beginning of treatment (T0), at T1 (4 weeks) and T2 (8 weeks). Results: Results showed a reduction of pain in both groups, with a better trend for group 1, where better results were achieved at T1 and maintained stability at T2, with an improved mean value regarding all parameters studied. After 8 weeks, only small recurrences started to occur in muscle pain to palpation in group 2. Conclusions: An occlusal appliance seems to be able to achieve a clinical improvement of Temporomandibular disorder (TMD)-related pain and headache, independently from the adjustment procedure adopted. However, the use of a surface electromyographic activity of masticatory muscles (sEMG) device as an aid in the calibration procedure seems to allow a better trend because the improvement of symptoms was obtained before, after the first four weeks, with an improvement in percentages of all the variables investigated. While the conventional procedure obtained later the improvement.
