Oxidative imbalance and anxiety in patients with sleep bruxism.

OBJECTIVE We evaluated the relationship among sleep bruxism (SB), antioxidant/oxidant status, and anxiety level to determine whether antioxidant/oxidant status may be used as a biological marker of SB. STUDY DESIGN Thirty-three SB and 32 healthy patients of similar age, sex, and body mass index were enrolled, venous blood was collected, and anxiety scores were determined. Plasma samples were analyzed for total oxidant status, antioxidant status, and oxidative stress index. RESULTS In 2 of the 3 assays performed, SB patients exhibited an oxidative imbalance. A higher anxiety score was observed with SB (P < 0.05). CONCLUSIONS These results show that oxidant/antioxidant imbalance may be related to SB, either pathophysiologically or as an outcome of the condition. Further biochemical studies could prove useful in determining the importance of antioxidant drugs in the treatment of SB.

Management of central giant cell granuloma of mandible using intralesional corticosteroids: case report and review of literature.

We read ‘‘Management of Central Giant Cell Granuloma of Mandible Using Intralesional Corticosteroids: Case Report and Review of Literature’’ by Ferretti et al. with great interest. The paper reports a case of managing central giant cell granuloma (CGCG) in a 16-year-old girl through the administration of intralesional corticosteroids. The authors state that complete opacification was noted after only 2 administrations of the steroid solution. They also report that this rapid response was unique among the cases previously reported. However, the authors did not compare the age of their patient and localization of the CGCG with previously reported cases. Even if their case was unique, their patient was only 16 years old and the lesion was located on the mandible. We believe that younger patients experience faster treatment responses. Also, the localization of the CGCG reported in their case may be related to the response. As is commonly known, the regeneration capability of the mandible is better than that of the maxilla. Because the authors did not report, in their literature review, the age and gender of the patients and the localization of the CGCGs covered, we would like to add these data to clarify things for readers (Table 1).

Clinicopathological study of jaw cysts in southeast region of Turkey.

Objective: The purpose of this retrospective study was to analyze clinic and radiologic features and the prevalence of jaw cysts in southeast region of Turkey. Materials and Methods: This study was carried out in 149 cysts of the jaw diagnosed among 407 individuals who were taken biopsy in our department from October 2008 to December 2012. All cysts were treated by enucleation, marsupialization, or combination, and all cases were histologically examined. Results: One-hundred-and-forty-eight cases were classified odontogenic, one was non-odontogenic. There were 89 cysts (59.7%) in men, 60 (40.3%) in women. The mean age was 32.72 years. We found 80 cysts (35 F, 45 M) in the maxillary and 69 (28 F, 41 M) in mandible. It is observed that 94 were radicular cysts (63%), 40 were dentigerous cysts (26.9%), 9 were odontogenic keratocysts (OKC) (6.1%), 5 were residual radicular cysts (3.4%), and 1 was nasopalatine cyst (0.6%). In radicular cysts, 56 of them (59.5%) were located in the anterior region of the jaws; 18 dentigerous cysts and 2 OKCs were found in the posterior region of mandible. Clinically, the chief complaint of patients was expansion and pain. Radiographically, scalloping of the lesion between the teeth was found in 1 case, root resorption was seen in 3 cases, and displacement of the teeth and follicles was observed in 16 cases. Conclusions: We found similar prevalence of jaw cysts that reported in the literature, in which most odontogenic cysts (OCs) were inflammatory origin.

Histopathological features of bisphosphonates related osteonecrosis of the jaw in rats with and without vitamin d supplementation

OBJECTIVE Aim of this study was to investigate the effect of vitamin-D3 on the osteonecrosis of bone that was induced after tooth extraction was conducted on rats that were given zoledronic acid (Z.A). MATERIAL AND METHODS Animals were divided into four groups. Two of the experimental groups were divided into two subgroups, third study group was not divided into subgroups, and control group was divided into three subgroups. Z.A was administered twice per week over the course of 7 weeks, dexamethasone was administered twice a week during the 5th-6th-7th weeks to all groups. Dental extraction was performed by drilling around the tooth at 7th week. In study-group-1; vitamin-D was administered twice per week during the 5th-6th-7th weeks. In study-group 2; vitamin-D was administered twice per week during the 8th-9th-10th weeks. In study-group-3; vitamin-D was administered twice per week during the 15th-16th-17th weeks. The animals were sacrificed at 10th-15th-17th weeks, and histologic samples were taken. RESULTS Postoperative-15-group had a lower osteoblast number, which was statistically significant as compared to preoperative-15 and control-15-group. Control-10-group showed significantly lower osteoclast number in comparison to preoperative-10 and postoperative-10-group. Osteoclast number was significantly higher in the osteonecrosis-17-group as compared to control-17-group. Preoperative-10-group showed significantly higher inflammation in comparison to control-10-group. Postoperative-15-group had a lower histologic osteonecrosis, which was statistically significant as compared to the control-15-group. Macroscopic osteonecrosis was significantly higher in the control-17-group in comparison to the osteonecrosis-17-group. CONCLUSIONS We concluded that there are some proofs for the treatment of BRONJ with systemic using of vitamin-D.

Study of kissing molars in Turkish population sample

Background: “Kissing” or “rosetting” of molars are extremely rare phenomenon with limited cases in the dental literature. It was first described in 1973, refers to contacting occlusal surfaces of the impacted mandibular second and third molars. The aim of the present study was to report the incidence of kissing molars (KMs), classification, incorporated pathologies, and its management in a group of Turkish population. Materials and Methods: The panoramic radiographs of the patients who referred to Gaziantep University Faculty of Dentistry between January 2012 and November 2014 for surgical treatment retrospectively were evaluated. The cases of KM were determined and evaluated with respect to its type, combined pathology, and treatment. Results: Of the 6570 radiographs included in the study, 4 were seen to present as KM illustrating 0.060% of the sample. Three cases were Class II (0.045%), and only one case was encountered as Class III (0.015%). The mean age at the time that the KM teeth were identified was 34 years with a range from 29 to 40 years. Three of the patients were male, one of the patients was female, and all cases were seen unilaterally. One of the KMs was associated with dentigerous cyst formation. Conclusion: KM is a very rare clinical condition and few treatment options described. Early detection is essential to preclude complications and to provide more successful treatment. In this study, we evaluated the cases of KM and review of the literature also presented.

Simultaneous oroantral communication closure, sinus‑lifting, and particulate bone grafting and immediate dental implant perforation

The aim of this paper is to introduce an alternative technique for the treatment of oroantral communication (OAC). Closure of OAC, reconstruction of the posterior maxilla by sinus-lifting procedure with a particulate xenograft, and implant insertion were performed in the same operation. A lateral antral approach was used in the sinus elevations. The sinus membranes were elevated gently around the perforation area, and then a barrier membrane was used to close the perforation. Care was taken not to extend the perforation. Next, the maxillary sinus was filled with a particulate xenograft, and an implant was inserted simultaneously. Forty-seven and 40 months of clinical and radiographic follows-up revealed healthy and functional implants in the teeth area.

PERIPHERAL OSTEOMA OF THE HARD PALATE: A RARE CASE REPORT AND LITERATURE REVIEW

Osteomas are benign osteogenic tumors that are composed of cancellous or compact bone. They are usually sessile tumours composed of dense sclerotic, well-formed bone projecting out from the cortical surface. They commonly occur in skull and facial bones, however, excluding the maxillary sinuses, the maxilla is a rare site for osteomas. Therefore, we aim to present a case of maxillary osteoma in a 19-year-old male patient and to provide an overview of current literature on the diagnostic options and treatment modalities. To best of our knowledge, in the English literature, this is the seventh reported case of maxillary osteoma which is located on the hard palate.

Simultaneous Retrieval of Root Fragment, Sinus Lifting With Particulated Bone Graft, and Immediate Dental Implant Insertion.

Abstract The aim of these 3 patient reports is to demonstrate a new technique for the reconstruction of the posterior maxilla in patient of a displaced root fragment. The retrieval of root fragments, sinus floor augmentation procedures with a particulated graft, and an implant insertion were performed in the same operation. A simultaneous oro-antral communication was also repaired in 2 patients. Sinus membrane elevations and retrieval of a root fragment via the lateral wall sinus approach were also performed. After repairing a membrane perforation with a particulated graft, an immediate implant insertion was done. An average period of 41 months of clinical and radiographic follow-up revealed a healthy maxillary sinus and a functional implant in the tooth area.

LARGE DENTIGEROUS CYST IN THE MAXILLARY SINUS LEADING TO DIPLOPIA AND NASAL OBSTRUCTION: CASE REPORT

Dentigerous cysts are the most common developmental odontogenic cyst of the jaws. They are more frequent in males and although most often affected teeth are maxillary canines and mandibular third molars, they may also be related with supernumerary or an ectopically erupted tooth. Our aim was to report the management of ectopic third molar tooth related with a dentigerous cyst in maxillary sinus. 16 years old girl referred to our clinic with a complaint of painful swelling over her right cheek since past six months. All permanent teeth were present except the right upper third molar. External examination showed that the face was gently asymmetrical; levels of eye globes were abnormal. Radiographic examination revealed a cystic lesion related with ectopic third molar which located in the roof of the left maxillary sinus. Under local anesthesia, hard drain was inserted into the hole and the cystic pressure was decreased. After the six month of followup, the operation was performed under general anesthesia. The patient’s symptoms were resolved completely after surgery and remained symptom-free for over a postoperative follow-up period of 3 year. To avoid unwanted effects of a dentigerous cyst, unerupted tooth should be observed with radiographic imaging. Some untreated dentigerous cysts may grow large and have a potential to develop into an odontogenic tumor.

The importance of endodontic treatment time in apical resection: Case report -

Aim of this case is report to discuss advantages and disadvantages of endodontic treatment and apical resection in same session. 22 years old female patient who has pain, swelling and pus discharge in upper incisors referred to department of endodontics. The patient was referred to our clinic due to long term of treatment and shortness of patient’s time. Endodontic treatment and surgery was performed in the same session. Fifteen month follow up of patient showed that wound is completely healed. During controls, no complication and recurrence were observed in patient. Today it has been discussed that endodontic treatment done before or during apical resection. Short term findings of patient are excellent, who underwent endodontic treatment and surgery in same session. In addition, patient is followed up in long term. Therefore, further studies are needed.
