Palatal talon's cusp of a permanent maxillary lateral incisor: A case report
M Saleem, D Deepa
July-September 2016, 13(3):162-164
Talon's cusp is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cemento-enamel junction. This anomaly occurs as a result of disturbances during the morphodifferentiation stage of tooth development. It mainly occurs in either maxillary or mandibular anterior teeth in both the primary and permanent dentition. Here, we report a case of talon's cusp on a permanent maxillary lateral incisor tooth.

Maha M Abo Shady, Ibrahim R Eltorky, Zeinb M Abd Eaal
July-September 2016, 13(3):157-161
Objective: The aim of this work is to compare between balls versus locator attachment systems for mandibular implant-retained single complete overdenture, as regards to clinical and radiographic evaluation. Materials and methods: Fourteen patients had lower edentulous jaw opposing almost natural dentition in the upper jaw was selected with their age ranging from 55 to 65 years. The patients were divided into two groups. Group I received single mandibular complete overdenture constructed over two implants, retained by ball attachments. Group II received single mandibular complete overdenture constructed over two implants, retained by locator attachments. Evaluation was carried out at regular appointments up to 1 year from time of loading of the implants. Each patient was presented to a questionnaire regarding retention, stability, comfort, chewing ability, esthetics, and speech. Clinically, the patients were evaluated as regards to gingival recession, pocket depth and implant stability. Radiographically, the patients were examined to determine the amount of marginal bone loss. Results: All fixtures were successfully osseointegrated all over the follow-up period. The results showed no significant difference in patient satisfaction between both groups (P = 0.827). Slight increase in the gingival recession was found in both groups throughout the time of observations, with no significant difference between both groups (P = 0.166). There was insignificant increased of the probing depth around the implants in both groups (P = 0.600). There was insignificant increase in implant stability in both groups throughout the follow-up periods (P = 0.839). No significant differences in bone loss were observed between both groups throughout the follow-up periods (P = 0.524 and <0.05). Conclusion: Two implants were sufficient to retain a single mandibular complete overdenture opposing maxillary natural dentition without hazardous effect on the implants.

Malak Y Shoukheba, Enas A Elgendy
July-September 2016, 13(3):133-138
Introduction: Oral lichen planus (OLP) is a chronic mucocutaneous disease with an immunological etiology. This study was conducted to evaluate the effect of coenzyme Q10 (CoQ10) as an adjunctive to topical corticosteroids in the treatment of erosive–ulcerative lichen planus. Materials and methods: A total of 30 patients with a confirmed clinical diagnosis of OLP participated in this clinical trial. Patients were randomly allocated into one of two groups and treated as follows: group I received topical corticosteroids and group II received CoQ10 combined with topical corticosteroids. Assessment of outcome measures including clinical score and pain was carried out at the time of initial visit (baseline) and at 2, 4, 8, and 12 weeks following treatment protocol. All recorded data were analyzed using paired t-test and independent t-test. The level of significance was established at a P value of 0.05 or less. Results: The two studied groups showed a marked reduction in pain sensation and size of lesions, particularly in the final follow-up period. However, healing and decrease in the size of the lesions were effective in group II, and a significant difference was found between the two groups favoring group II over group I. Conclusion: CoQ10 in combination with topical corticosteroids was found to be effective in managing ulcerative lesions of OLP; however, more studies with a larger sample sizes and longer duration with evaluation of the adjunctive effect of CoQ10 on inflammatory markers expressed in OLP are recommended.

Mohamed G Elkafrawy, Fadel A Abd Elfatah, Ften A Abu Talep
July-September 2016, 13(3):139-146
Purpose: To compare clinically and radiographically between two different implant lengths for implant-assisted complete mandibular overdenture. Patients and methods: Twenty completely edentulous male patients with age range 55–65 years old were equally divided into two groups, for group I a maxillary complete denture and a mandibular implant-assisted complete overdenture were constructed for each patient using two implants with 3.6-mm diameter and 10-mm length with O-ring attachments were placed at the canine regions of the mandibular alveolar ridge while for group II a maxillary complete denture and a mandibular implant-assisted complete overdenture were constructed for each patient using two implants with 3.6-mm diameter and 12-mm length with O-ring attachments and placed at the canine regions of the mandibular alveolar ridge. Each patient was evaluated clinically as regards to patient satisfaction, gingival recession, probing depth, and stability test by using Osstell ISQ and radiographically by panoramic evaluation at denture insertion then after 3, 6, and 12 months. Data were collected and statistically analyzed using the unpaired t-test between the two groups and paired t-test within the same group. Results: There was no statistical significance difference between the two groups as regards to clinical and radiographic evaluation; on the other hand, there was significant difference within the same group. Conclusion: Two dental implants with length 10 mm are sufficient to assist complete mandibular overdenture with opposing conventional maxillary complete denture and there was no significance difference in implant stability between 10 and 12 mm dental implant length by using Osstell ISQ. According to the clinical results, based on the clinical parameters used in this study, the findings revealed healthy peri-implant conditions throughout the study period in both groups, with no significant difference between the two groups.

Biologic reinforcement of compromised permanent incisors in children
Talat M Beltagy
July-September 2016, 13(3):147-156
Purpose: The aim of this study was to evaluate the clinical and radiographic success of biologic primary incisors as intraradicular post–core reinforcement in management of compromised permanent incisors in children. Patients and methods: Twenty-four children patients aged 10–15 years old were selected from Outpatients Clinic of Pedodontic Department, Faculty of Dentistry, Tanta University. The patients had upper permanent central incisors with flared canal indicated for intraradicular reinforcement. The patients were randomly divided into two groups, 12 patients each; biologic group were reinforced by human extracted primary incisors, and fiber post group that their compromised teeth were reinforced by fiber posts (EasyPost) with RelyX Unicem. Clinical assessment of jacket crowns, gingival health, reinforced permanent teeth, and intraradicular reinforcing system was recorded. The healthy periapical area (no pathosis), pathosis did not require immediate treatment and pathosis required immediate treatment were recorded as radiographic assessment. The children were followed up clinically and radiographically at 3, 6, 12, and 18 months after treatment. Results: The overall clinical success rate of biologic group was 75 and 100% for fiber post group. There were no statistically significant differences in clinical assessment between the two groups (P > 0.05). The overall radiographic success rate of biologic group was 77.8 and 83% for fiber post group at the end of study. There were no statistically significant differences in radiographic assessment between the two groups (P > 0.05). Conclusion: The use of extracted primary incisors as biologic post–core in rehabilitation of compromised flared upper central incisors have continued to function well for 1.5 years with overall clinical and radiographic success rate of 75 and 77.8%, respectively.

Fatma A Elhadad, Fadel A Abd Elfatah, Nahed A Kashef
July-September 2016, 13(3):119-126
Objective: The objective of the present study was to compare between two different clasp materials for the treatment of maxillary class II Kennedy classification clinically, radiographically. Materials and methods: Twenty male patients were selected for this study. The patients were divided into two groups. Each group consists of 10 patients. For group I each patient have maxillary removable partial denture that was constructed and retained by cobalt–chromium RPI clasp on the maxillary first premolar with cross arch stabilization (using double Aker clasp) on the other side. For group II each patient has the same except that the retentive I bar of RPI clasp was made of acetal resin. Patient satisfaction, clinical, and radiographic evaluations were carried out for every patient at insertion, 3, 6, and 9 months, the data were collected, tabulated, and statistically analyzed using t-test. Results: Satisfaction for the treatment. Group II patients were more satisfied of the treatment regarding aspects of the patients' comfort and esthetics. No significant difference in the aspects of phonetics, the ability to eat, prosthesis loosening, the gingival health, general satisfaction and food impaction between the two groups were found, also there were insignificant increase in the gingival recession, pocket depth, and plaque index around the abutments tooth in both groups. Radiographically, there was significant decrease in the bone height around the abutments in both groups. Conclusion: Removable partial denture with acetal resin clasp is better for esthetic and patient comfort. Good periodontal condition of the abutment tooth of both groups is maintained. Acetal resin clasp is the clasp of choice when esthetic is of primary concern to the patient.

The effect of plasma surface treatment on push-out bond strength of fiber-reinforced posts to root canal dentin
Usama M Abdel-Karim, Hatem A Alhadainy
July-September 2016, 13(3):127-132
Objectives: This study evaluated the effect of surface treatment with plasma or sandblasting on push-out bond strength of fiber post bonded to root canal dentin. Methods: Crowns of 50 teeth were sectioned and their root canals were instrumented, obturated and received post-space preparations. The roots were equally divided into five groups according to post surface treatment. Posts were surface treated with oxygen plasma in Group 1 and argon plasma in Group 2. Post surfaces were treated with sandblasting in Group 3 and silanized after sandblasting in Group 4. In control group (Group 5), posts were cemented to the canal wall without surface treatment. After post cementation, push-out test was used to evaluate the bond strength of fiber post bonded to root canal dentin. Data were statistically analyzed using Kruskal-Wallis and Mann-Whitney tests (α = 0.05). Results: Oxygen plasma revealed the significantly highest push-out bond strength of all groups (P < 0.01). No significant difference was found between argon plasma and control group. Sandblasting significantly improved the bond strength compared to control group. The difference between sandblasted and sandblasted-silanized groups was not significant. Conclusions: Oxygen plasma treatment of fiber post recorded the highest bond strength to root canal dentin followed by sandblasting. Silanization and Argon plasma did not play a significant role in enhancing bond strength of fiber posts to canal dentin. Clinical significance: Oxygen plasma surface treatment offered the highest resistance to displacement of fiber posts. Clinical trials involving plasma technique are indicated.
