Lymphangioma circumscriptum is a benign lymphatic malformation that usually presents at birth or early childhood. Acquired oral lymphangioma has been reported secondary to radiation therapy and denture‐induced trauma due to damage to previously normal lymphatics. To the best of our knowledge, this is the first report of acquired oral lymphangioma due to childhood tuberculous adenitis.
Objectives: The purpose was to compare shear bond strength (SBS), pulp temperature, and adhesive remnant index (ARI) in debonding of stainless steel brackets from enamel surface using neodymium-doped yttrium aluminum garnet (Nd:YAG) laser versus the conventional debonding method. Materials and Methods: Forty-eight extracted premolars were bonded to stainless steel brackets. The samples were divided into three experimental groups and one control group. In the first three groups, Nd:YAG laser was used for debonding with the power of 1, 1.5, and 2 W, respectively, for 10 seconds. The SBS and ARI of the samples were assessed. Pulp temperature was recorded before and after irradiation. Two samples from each group were used for determining enamel morphology after debonding using scanning electron microscopy (SEM). Results: The mean SBS in the groups was 33.05, 28.69, 24.37, and 31.53 MPa, respectively, with no statistically significant differences (P=0.205). Significant differences in post-irradiation temperature were noted among the lased groups (P=0.000). Debonding mainly occurred at the adhesive-enamel interface in the 1-W laser and control groups and at the bracket-adhesive interface in the 1.5-W and 2-W laser groups. Enamel structure was amorphous and irregular following laser irradiation. Conclusions: Based on the results of this study, the use of Nd:YAG laser could not significantly affect the SBS. Therefore, this laser would not be suitable for debonding of metal brackets. The use of a 2-W laser could significantly raise the pulpal temperature. Nd:YAG laser renders a more heterogeneous enamel morphology compared to conventional debonding methods.
Aim: Pain is one of the clinical problems after orofacial surgeries. There have been various studies about the analgesic effect of nonsteroidal antiinflammatory drugs (NSAIDs) in this group of surgeries. In recent years, meloxicam has undergone clinical trials in dentistry. The purpose of this study was to review the efficacy of meloxicam on postoperative pain in dentistry. Materials and methods: The study design was in accordance with the PRISMA guidance. The keywords according to MeSH and related articles were searched in the EBSCO, MEDLINE (via Ovid), PubMed, Science Direct, Scopus, Web of Science and Google Scholar databases. Then eligible randomized clinical trials articles, which released up to December 2017, were thoroughly reviewed. Results: The nine eligible articles were studied. Meloxicam was administered with doses of 7.5, 10 and 15 mg (oral or intramuscular) before or after the third molar extraction. Meloxicam has a similar or significantly better analgesic effect than some of the selective and nonselective NSAIDs and significantly has a better analgesic effect than some of salicylic acids and tramadol. Conclusion: Meloxicam can be considered as an alternative analgesic agent than some NSAIDs, tramadol and salicylic acids in patients who have undergone the third molar extraction.The best way to pain intensity control following orofacial surgeries has not yet been introduced. According to a common rule, non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen or their combination are the most prescribed items for of pain intensity control after orofacial surgery 6,7 .Up to now, many studies have been conducted to evaluate the effectiveness of different analgesic drugs, including opioids, corticosteroids, salicylic acids and NSAIDs in dentistry. Generally, selective cyclooxygenase-2 (COX-2) inhibitor NSAIDs may be preferred over their non-selective ones in terms of pain intensity control and a decrease in additional Oral Surgery 13 (2020) 188--196.
Background: Impacted tooth is common in dental practice. Dentists usually remove them if they are associated with any pathologic sign or symptom. The challenge is whether to extract the asymptomatic tooth or not. This study was conducted to determine the association between developmental odontogenic cysts and tumors and impacted and unerupted teeth, if left untreated. Methods: In this matched case-control study, 262 participants were recruited in case and control groups to evaluate the association between the presence of odontogenic cyst and tumors and unerupted and impacted teeth in patient records in the School of Dentistry, Shahid Beheshti University of Medical Sciences during 2000-2002. The controls referred to a dental radiology center for routine OPG. We also recorded the data on age, gender, the involved jaw, and type of lesion. All patients’ records were reviewed by the research director and an oral pathologist separately. The variables that were matched as confounders were age, gender, and the site of the involved jaw. Results: Results of conditional logistic regression analysis showed that the presence of odontogenic lesions was associated with impacted teeth (OR = 6.9), and not associated with the involved jaw and unerupted teeth. Conclusion: Impacted teeth could be considered as a potential risk factor for the presence of odontogenic lesions.
e anterior maxilla is the most prone region to the trauma during childhood, and tooth loss sometimes happens due to trauma. Replacing the missing teeth has always been one of the dentists' challenges in children and adolescents, since their dentofacial growth is not complete. Autotransplantation of mandibular premolars with two-thirds or three-quarters of root formation provides the best prognosis for the tooth survival. is case report describes the management of a 10-year-old boy suffering a severe dental injury who received the autotransplantation of the premolars from mandible to restore the space caused by trauma in maxillary central incisor region and a 13-year follow-up of the autotransplantation.
