  Oral-gingival myiasis is known as an infectious condition in human due to the invasion of tissue by larvae of houseflies. This study presents a case of gingival myiasis in an 8 year-old Iranian girl, leaving in a rural community. She had reported concerns an live worms (larvaes) crawling out of her gingival sulcus. Clinically, patient had a swelling and a tunnel shaped sulcus in palatal gingiva of her maxillary right lateral incisor tooth. The lesion was treated by a simple curretage and irrigated with saline solution. The larvaes were identified and removed during the procedure and sernt for further parasitologic investigations. Oral Myasis like the present case, is seen in cases with poor oral hygiene. Special care is needed to manage and control its clinical complications to prevent recurrence.

  The aim of this study was to compare clinical as well as radiographic status of periodontal tissue of carious or badly restored teeth in comparison to healthy adjacent ones. A group of 50 individuals aged 20-50 years were selected from those referred to periodontics department at Shahid Beheshti Medical University for their periodontal complications including bleeding and recession. Clinical and radiographic examinations were performed on cases including Bleeding on Probing (BOP) pocket depth, attachment and bone loss level. All posterior teeth were looked at for presence of caries or faulty restorations. Similar number of cases were also assessed from the adjacent sound teeth as control. Collected data were then analyzed using P2-test. There was a significant association between the presences of defective restoration and periodontal disease. A similar finding was corresponded to the presence of active carious lesion. This change of the periodontal tissue status was not observed on the sound adjacent teeth. Comparing the different groups for their power of difference, the sound and either carious or faulty restored teeth showed no significant difference between periodontal status of carious and restored teeth (p<0.05). Results of this investigation revealed that faulty restored and carious teeth could develop periodontal disease through out time and any delay in treating such cases would further complicate the case.

  Structurally defected teeth are not only weak but also provide favorable areas for colonization of bacteria. This subsequently will increase the incidence of dental caries in such dentition. Enamel hypoplaisa is considered one of many caries inducing factors. The aim of this investigation was to evaluate the frequency of dental caries among hypoplastic teeth in a group of 6-9 years old Iranian children. One hunder and one children of 6-9 years of age from Paedodontic Department of Shahid Beheshit Dental School were randomly selected. All the primary and permanent teeth of these children (2266 teeth) were examined for the Presence of enamel hypoplasia and dental caries. Overall, 1671 of teeth (73.9%) were primary and 589 (26.1%) were permanent. Of the permanent teeth, 315 were first permanent molars. Pearson, Mantel Haenszel and Fisher Exact test were used to analyze the data. A significant relationship was found between enamel hypoplasia and dental caries both in permanent (p<0.0001) and primary teeth (p = 0.038). The odds ratio was 7.362 for all the permanents, 4.47 for the first permanent molar and 1.887 for the primary teeth. Hypoplastic teeth are more likely to develop caries than non-hypoplastic teeth. Hypoplastic primary teeth are 2 times and the 1st permanent molars are 4 times more susceptible to dental caries than non-hypoplastic ones.

  This study was designed to evaluate clinical and radiographic success rates of Mineral Trioxide Aggregate (MTA) as a relatively new pulpotomy agent for pulp treatment of primary teeth. This prospective investigation was carried out on a group of children with a mean age of 6.4 years who were referred to Shiraz Dental School for routine care. Pulp amputation was carried out following routine local anesthetic induction on selected primary molars and then MTA (Pro root, USA) was placed over the already formed clot at the canal orifices. All teeth were restored using Stainless Steel Crowns and a recall program was set for 6, 12 and 24 months. Clinical and radiographic evaluations were attempted in all recall visits. Overall 55 primary molar teeth were treated by this new technique 4 of which failed for any follow-up evaluations. Apparently, all of the remaining 51 treated teeth were found to be sound and without any sign or symptoms both by clinical and radiographic means (100% success at 12 and 24 months), postoperatively. Based on the findings of this study, it seems that MTA could be used as an alternative to the current Formocresol medication with high clinical and radiographic success in pulpotomy of primary teeth.

  After the third molar, congenitally missing of second premolars has the highest incidence. Endodontic treatment of second primary molars is therefore, of prim importance for a longer lasting tooth. The aim of this article was to look at the potential improvement and longevity of 2nd primary molar root canal therapy using Gutta percha when missing successors. A 9 year old male patient was attended to the Department of Pedodontics, Shahid Beheshti University, for routine check up. There was no report of any medical problem in his history. Radiographic investigation of the case using an OPG revealed the missing of both lower 5ís. This was while both mandibular 2nd primary molars were carious involving pulp. All carious tissues were removed followed by an opening into the pulp chamber under local anesthesia and rubber dam isolation. The inflamed and hyperemic pulp was removed as routine, irrigated, dried ready for root filling. All three root canals were then dressed temporarily using a cotton pellet placed in to the pulp chamber covered with reinforced ZOE. Each root of the treating teeth was then obturated in the second visit using Gutta-percha and ZOE sealer through the lateral condensation technique. Radiographs were obtained before, immediately after and in 6 month follow up to assess the periapical as well as forcation of the teeth. Second primary molars with missing successors tend to stay intact in a longer period when treated with Gutta Perchae root filling compare to Pure ZOE paste as they would not resorbe quickly.
