weight fractions (AHM) containing native ingredients of polysaccharide (acemannan) and glycoprotein (verectin) were obtained by using the patented hyper dry system after washing out coloured materials with running water from Aloe vera gel slurry. Forty-six primary first teeth from children between 6-9 years, which formerly planned for serial extraction were selected. The children were distributed into two equal groups; twelve teeth for each. Pulpotomy was done in both groups; where group I treated by AHM, acemannan, as a dressing agent while formocresol used as a dressing agent in group II. The teeth from each group were extracted at two, four, and twelve week intervals for histopathological evaluation. RESULTS: In group I (Acemannan), after twelve weeks significantly better results in pulp inflammation, incomplete dentine bridge formation, and soft tissue organization were demonstrated (p < 0.05). Most of the acemannan-treated group demonstrated no pulp inflammation with only (3/12, 25%) revealed mild pulp inflammation under the exposure site and only one tooth 1/12 teeth (8.3%) showed partial dentine bridge formation. In contrast, group II (Formocresol) moderate or severe pulp inflammation (10/12, 83%), no dentine bridge formation were observed. In almost all cases (10/12, 83%) the soft tissue of the pulp was not well organized. CONCLUSION: According to these findings, AHM, acemannan may be a suitable agent for pulpotomy in primary teeth. Moreover, the inflammatory response was less severed and no necrosis was noted after pulpotomy with acemannan compared to formocresol.
AIM: The present study was conducted to compare effects of acemannan and formocresol as pulp-dressing agents clinically and radiographically in primary teeth. MATERIALS AND METHODS: Aloe vera gel high molecular weight fractions (AHM) containing native ingredients of polysaccharide (acemannan) and glycoprotein (verectin) were obtained by using the patented hyper dry system after washing out coloured materials with running water from Aloe vera gel slurry. Thirty healthy children aged from four to eight years, they were selected from patients attending outpatient clinic of Pediatric Dentistry department. Each child had at least bilateral deep carious lower primary molar indicated for pulpotomy. Pulpotomy was done in both groups; where group I treated by AHM, acemannan, as a dressing agent while formocresol used as a dressing agent in group II. The study cases were recalled after three, six, nine and twelve months for clinical and radiographic evaluation. RESULTS: The overall clinical success rate of acemannan group was 96.5%, while formocresol group was 89.6%. The two groups were clinically successful with no statistically significant difference between them (p = 0.148). The radiographic success rate of acemannan group was 93.1%, while for formocresol group was 86.2%. There was no statistically significant difference between the two groups (p = 0.385). CONCLUSION: The acemannan showed higher clinical and radiographic success rate compared to formocresol as a pulpulpotomy agent in molars. It can be considered as an acceptable biomaterial for vital pulp therapy of deep caries in primary teeth.
The aim of this clinical study was to cephalometrically investigate profile changes after using a palatal crib and fixed orthodontic appliance therapy, in children with thumb sucking. Fifteen females with age ranged from 8 to 10 years were used in this study, irrespective of the molar relationship. Lateral cephalometric X-ray films were taken before and after treatment, and sixteen variables were measured and statistically analyzed using a paired t-test. Before and after treatment differences were statistically significant for all variables except mandibular apical base relationship and maxillary length. Dentoalveolar changes were evidenced as retrusion and extrusion of incisors and decrease in the open bite and overjet .The dento-skeletal changes implied soft tissue changes in the form of retracted upper and lower lips , decreased interlabial gap, and increased nasolabial angle. On the basis of the data obtained it could be concluded that the break of the habit allow skeleto-dental and soft tissue improvement, and early intervention of thumb sucking are essential to re-establish the adequate growth and development potential.
