Introduction
The study was designed to evaluate the anesthetic efficacy of 4 % articaine with 1:100,000 epinephrine (A100) in infiltration and inferior alveolar nerve block (IANB) anesthetic techniques for the pain control during extraction of the mandibular posterior teeth.Methods
This prospective randomized single-blind clinical trial included 100 patients needing extraction of at least two mandibular molars. Patients received either infiltration in the buccal vestibule opposite to the first molar supplemented with lingual infiltration or standard IANB with A100. For assessment of depth of anesthesia obtained by the two anaethetic techniques, presence or absence of pain during the extraction were rated using the visual analog scale.Results
Fifty patients received infiltration anesthesia and fifty patients were anesthetized by IANB. The success rate of pain-free extraction after buccal infiltration was 94 %, whereas by using IANB with the same anesthetic it was 92 %. No statistical differences were detected in the success rates between the two anesthetic techniques (P = 0.15).Conclusions
Buccal Infiltration can be considered a good option during extraction of the mandibular molar and premolar teeth of course, with supplemental lingual anesthesia.2.

Objectives
The aim of this study was to evaluate the influence of systemic administration of antibiotics (amoxicillin and tetracycline) at the different phases of the repair process (7, 15, 30 days) in immediate rat tooth replantation.Materials and methods
Ninety rats had their incisors extracted and stored in saline for 5 min. Next, the teeth were replanted, and the animals were assigned to three groups according to the antibiotic administered by oral gavage: control group, amoxycillin group, and tetracycline group. Euthanasia was performed at 7, 15, and 30 days after replantation.Results
Regardless of the evaluation period, the connective tissue underlying the epithelial attachment and the periodontal ligament showed statistically significant difference relative to the acute inflammatory infiltrate, which was more intense in the control group followed by the tetracycline group.Conclusion
These results point to the fact that systemic antibiotic therapy (SAT) in immediate tooth replantation is beneficial to pulpal and periodontal ligament repair and that amoxycillin is an excellent option.Clinical relevance
There is a lack of randomized studies assessing how the use of systemic antibiotics could influence tooth healing after immediate replantation.3.

Purpose
To determine the quantity of dexamethasone plasma concentration achieved following intrapterygomandibular space injection of dexamethasone when co-administered with inferior alveolar nerve block correlating with the clinical effects in the postoperative phase.Objective
A preliminary prospective study to evaluate the dexamethasone plasma concentration achieved following intrapterygomandibular space injection of dexamethasone with 2% lignocaine inferior alveolar nerve block to achieve hemi-mandibular anesthesia for minor oral surgical procedures and derive clinical correlations.Background
Dexamethasone is a glucocorticoid, chiefly used for the management of postsurgical sequelae like trismus and swelling in maxillofacial surgical practice. Conventionally, parenteral dexamethasone is administered via intravenous or intramuscular route. Intrapterygomandibular space injection is a novel route of steroid delivery described in literature. For minor oral surgical procedures in maxillofacial surgical practice requiring inferior alveolar nerve block, dexamethasone can be administered along with local anesthetic through a single injection as a mixture (twin mix).Methods
Prospective double-blind randomized clinical trial was designed to evaluative plasma concentration of dexamethasone achieved following injection of a freshly prepared mixture of 1.8 ml of 2% lignocaine with adrenaline (1:200000) and 1 ml (4 mg) dexamethasone [2.8 ml solution of twin mix] in the pterygomandibular space. The 30 candidates included for the trial were randomly split into three study groups (ten each)—(1) control group (C); (2) intramuscular group (IM); (3) intraspace group (IS).Results
The mean plasma dexamethasone concentration at 30 min postinjection in group IM was 226.41?±?48.67 ng/ml and for IS group it was 209.67?±?88.13 ng/ml. Post hoc (Bonferroni-Holm test) intergroup comparison for plasma dexamethasone concentration (IM and IS) was found statistically insignificant (P?=?0.605).Conclusion
Intraspace route of drug administration can be utilized to deliver dexamethasonized local anesthetics safely with predictable clinical effects in the patients requiring mandibular minor oral surgery under local anesthesia.4.

Objectives
To compare the effectiveness of bupivacaine with adrenaline with that of carbonated bupivacaine with adrenaline on pain, onset of anesthesia and duration of anesthesia following surgical removal of impacted mandibular third molar.Study design
All the patients who underwent surgical removal of impacted mandibular third molar and who fulfilled our inclusion and exclusion criteria from 1st June 2013 to 30th June 2014 were included in our study. Patients who were diagnosed as having impacted mandibular third molar were randomly allocated to two groups namely group A (bupivacaine with adrenaline), group B (carbonated bupivacaine with adrenaline). Pain during deposition of local anesthetic, onset of anesthesia and duration of anesthesia were compared between the two groups. The collected data were subjected to statistical analysis by Chi Square test, Mann–Whitney U test.Results and conclusion
The efficacy of carbonated bupivacaine with adrenaline is more compared with bupivacaine with adrenaline in decreasing pain on deposition of local anesthetic solution and in rapid onset of anesthesia. The duration of anesthesia for carbonated bupivacaine with adrenaline and bupivacaine with adrenaline had no significant difference. The use of carbonated bupivacaine with adrenaline will reduce the patient discomfort both intra-operatively and post-operatively.5.

Purpose
It is believed that whenever we inject local anesthesia into the palate it is a painful experience for the patients. The aim of this study was to make palatal anesthesia painless by adding 7.4% sodium bicarbonate as an adjunct in local anesthesia.Methods
Fifty subjects requiring extraction of maxillary bilateral premolar teeth for orthodontic purpose free from periapical infections. These extractions were divided in such a way that all right-sided extractions were done under 2% lignocaine with 1:80,000 adrenaline; and all left-sided extractions were done under 2% lignocaine with 1:80,000 adrenaline with 7.4% sodium bicarbonate added. All extractions were performed using a consistent intra-alveolar technique by a single operator. Both the patient and the operator were blinded to the contents of the local anesthetic solution. Data records of these patients were procured on the basis of VAS and VRS, requirement of repeated injection, and onset and duration of anesthesia.Results
Clinical and statistical data confirmed that the addition of sodium bicarbonate in local anesthetics reduces pain and decreased the onset and increased duration of local anesthesia in the palatal site, as compared to injection of local anesthetic without sodium bicarbonate.Conclusion
Effect of sodium bicarbonate on reducing pain while injecting into the palatal aspect was noted in this study.6.

Objectives
The present study evaluated the degradation of collagen matrix (CM) immersed in tetracycline (TTC) or phosphate-buffered saline (PBS) in diabetic and normoglycemic rats.Materials and methods
Diabetes was induced in 15 rats by systemic streptozotocin (STZ) (experimental); 15 healthy rats served as controls. One day before implantation 60 CM disks, 5 mm in diameter, were labeled with biotin: 30 were immersed in tetracycline (TTC) and 30 in PBS. One disk of each type was implanted subdermally in each rat. Animals were euthanized after 3 weeks, and tissue specimens containing the disks were prepared for histologic analysis. Horseradish peroxidase (HRP)-conjugated streptavidin was used to detect the remaining biotinylated collagen. Residual collagen area within the CM disks was analyzed and compared to baseline.Results
Diabetes significantly increased the CM degradation. Immersion of the CM disks in a 50-mg/mL TTC solution before implantation decreased its degradation both in diabetic and normoglycemic rats.Conclusions
Diabetes significantly increases collagen matrix degradation; immersion of collagen matrix in TTC before implantation decreases its degradation in both diabetic and normoglycemic conditions.Clinical relevance
Immersion of medical collagen devices in TTC may be an effective means to decrease their resorption rate and increase their effectiveness, especially in situations with increased degradation such as diabetes.7.

Purpose
We report the results of the intralesional steroid injections for the management of central giant cell granuloma (CGCG) of the jaws.Methods
Seven CGCGs were treated with intralesional injection of corticosteroids. To accomplish this, 3.5 mL of triamcinolone and 3.5 mL of 0.5 % marcaine with 1/200,000 epinephrine (total 7 mL) were mixed. An adequate amount of steroid was injected into different areas of the lesion. This procedure was repeated on a weekly basis for 6 weeks.Results
Clinical and radiological examination showed complete resolution and ossification of the lesions in four patients. Partial recovery was achieved in two patients. One patient did not respond to the treatment and underwent surgical curettage.Conclusions
We suggest that intralesional steroid injection is safe and effective for the treatment of CGCG, especially in non-aggressive lesions.8.

Objective
We analyzed patients with advanced parotid malignancy requiring proximal facial nerve exposure undergoing mastoidectomy versus lateral temporal bone resection to determine differences in local and distant recurrence.Study design
The study design is a case series with chart review.Setting
The setting is in Tertiary care practice in Fort Worth, Texas from January1998 to January 2014.Subjects and methods
The study included 120 patients with advanced parotid malignancy, 82 males between 19 and 87 years, and 38 females between 26 and 83 years. Patients with no overt bone involvement were treated with parotidectomy and mastoidectomy for exposure of the proximal facial nerve, and patients with clinically suspected (radiographic imaging or clinical fixation) bone involvement were treated with parotidectomy and lateral temporal bone resection. Follow up ranged from a minimum of 18 months to 11 years following surgery.Results
Sixty patients were treated with mastoidectomy and 60 were treated with lateral temporal bone resection. In patients treated with mastoidectomy, 13 had local recurrence and 7 had distal recurrence. In patients treated with lateral temporal bone resection, 2 had local recurrence while 9 had distant recurrence. Statistical analysis revealed that patients treated with mastoidectomy developed local recurrence (p = 0.0022) more commonly than those treated with lateral temporal bone resection. There was no significant difference in distant recurrence between both groups (p = 0.5949).Conclusions
Patients with advanced parotid malignancy should be treated aggressively with parotidectomy and lateral temporal bone resection regardless of bone involvement due to increased risk of local recurrence in those treated with mastoidectomy alone.Level of evidence
Level of evidence is a 4 case series.9.

Purpose
The aim of the study was to analyze the eligibility of resorbable collagen membrane in the treatment of midfacial fractures to prevent gap formation and subsequent cheek tissue retraction.Material and methods
We included nine patients (six males, three females; mean age 51; range 20–73 years; mean bone gap size 8.03 × 13.12 mm) in a retrospective study design. The defect size was assessed by ultrasound.Results
After a healing period of 4 to 55 weeks, treatment resulted in a significant reduction of gap size (residual mean bone gap size 6.14 × 7.32 mm).Conclusions
Native resorbable collagen membrane is a promising tool to reduce the size of bony gap in midfacial defects.10.

Introduction
Reliable profound mandibular block anesthesia is questionable when depositing the anesthetic solution at the lingula. The Gow-Gates technique is an useful alternative to the classical inferior alveolar nerve block and the incidence of unsuccessful anesthesia may be as high as classical technique. The aim of this study is to compare the clinical efficacy, degree of patient acceptability, advantages, disadvantages and limitations of the classical and Gow-Gates techniques for providing anesthesia in patients undergoing bilateral symmetrical surgical removal of impacted mandibular third molar under local anesthesia.Material and Methods
The split mouth design study was conducted on 100 patients aged between 20 to 40 years undergoing surgical removal of bilateral symmetrical impacted mandibular third molar performed by the same maxillofacial surgeon. 2 ml of 2 % lignocaine hydrochloride with 1:80,000 adrenaline was used as a standard local anesthetic solution in all the cases. By using four-digit numbers from a random number table, either Gow-Gates or classical inferior alveolar nerve block were randomly assigned to either left or right sides in each patient. The injections were administered by another surgeon who was blinded to the experiment. The patient was assessed for Pain experienced during injection, frequency of positive aspirations, Onset and duration of anesthesia and Nerves anesthetized.Results
Results were statistically analyzed by Mann–Whitney and chi square test. A ‘P’ value of less than 0.05 was considered for statistical significance. Higher mean pain during injection was recorded in classical group, was found to be statistically significant. No significant association was observed between aspiration and the groups. Higher mean onset of anesthesia was recorded in Gow-gates group, was found to be statistically significant. Higher mean duration of anesthesia was recorded in Gow-gates group, was not statistically significant. Higher success rate was recorded in Gow-gates group and was statistically significant.Conclusion
If we ignore delayed onset of anesthesia of Gow gates technique, it is found to be more reliable, beneficial and have higher success rate than classical inferior alveolar nerve block technique.11.

Purpose
The purpose of this study was to find a suitable anesthetic combination for complicated and protracted minor oral surgical procedures.Methods
Fifty patients with bilaterally impacted deep-seated mandibular third molars were included in this study and randomly divided on the basis of anesthetic used into two groups. Group A received 2% lignocaine with 1:200,000 adrenaline while in group B, amalgamated mixture of 2% lignocaine and 0.5% bupivacaine was used. The onset time, duration of anesthetic effect, supplementary injections, pain (during local anesthetic deposition, intra and postoperatively), and postoperative analgesia were the study parameters. Chi-square and unpaired t tests were used to compare means.Results
The onset time in both the groups was comparable and showed statistically significant difference between the duration of anesthetic effect with notable requirement of supplemental anesthetic injections in group A (54%) (p?<?0.05). Pain scores also revealed a statistically significant intergroup difference (p?<?0.05). Requirement of postoperative analgesics was delayed in group B.Conclusions
The amalgamated mixture of lignocaine and bupivacaine had equivocally rational onset and provided a more profound and in-depth anesthesia especially in complicated and protracted minor oral surgical procedures. Though this mixture is widely used in other surgical fields, its efficacy still remains unexploited and undocumented in oral and maxillofacial surgical procedures.12.
Objective
The aim of this study was to assess the results of open reduction and internal fixation (OR/IF) of isolated mandibular fracture under regional anesthesia using mandibular nerve block.Patients and methods
This prospective study was carried out on 44 patients who had isolated traumatic parasymphyseal mandibular fractures. All patients were managed by OR/IF by two titanium miniplates using manual maxillomandibular fixation (MMF). All patients were sedated by (0.05 mg/kg) midazolam and (2 μg/kg) fentanyl. The patients were randomly classified into two groups: the control group (22 patients) treated under general anesthesia (GA) and the study group (22 patients) repaired under regional anesthesia. The results were assessed as regards dental occlusion, average intrinsic vertical mouth opening, actual operative time, complication, tolerance and patient’s satisfaction, and postoperative hospital stay time.Results
Both groups were matched for age and sex. There were no statistically significant differences of the postoperative complication, dental occlusion, and mouth opening between both groups. Duration for anesthesia induction, intubation, and anesthesia recovery was not needed in regional anesthesia. Regional anesthesia was tolerable and highly satisfactory in all patients with no intraoperative or postoperative anesthesia-related problems and no reported complications.Conclusion
Regional anesthesia can effectively replace GA in selected cases of mandibular fracture obviating the risks of GA.13.
Objectives
Studies on bone mineral density and fracture risk in diabetic patients have attracted interest in the last few years. This study was aimed at comparing mandibular osteoporotic changes assessed by qualitative and quantitative radiographic methods in the mandibles of type 2 diabetes mellitus patients with those of non-diabetic subjects using cone beam computed tomographic images.Methods
This quantitative and qualitative study of mandibular bone in diabetic patients included 23 type 2 diabetes mellitus patients and an equal number of healthy subjects. Radiomorphometric measurements were performed for each subject using cone beam computed tomography images. Changes in cortical bone thickness were determined by measuring bone area. Fractal dimension analysis was applied to evaluate the trabecular structure of the bone.Results
No statistically significant difference could be established between the type 2 diabetes mellitus group and the control group in regard to either radiomorphometric measurements or fractal dimension analysis. Quantitative assessment of mandibular bone indicated a thinning of the cortical bone, with a statistically significant difference between the type 2 diabetes mellitus patients and the healthy controls.Conclusions
Bone condition related to diabetes involves complex pathophysiological mechanisms; thus, radiographic imaging parameters may be useful as an adjunct to clinical parameters.14.

Objectives
Asymmetries of the jaw and orthodontic abnormalities are suspected as long-term consequences of positional cranial deformity. But only few data exist on this issue. As plagiocephaly is a common problem in infancy, potential functional impairments should be investigated to initiate appropriate measures if necessary. The aim of our study was to compare the orthodontic situation in primary dentition of children with positional plagiocephaly and children without cranial deformities.Material and methods
Fifty children treated by helmet therapy for plagiocephaly and 50 non-affected children (age 1.98–5.69 years) were examined in a cross-sectional study. Orthodontic parameters of all dimensions were assessed and analyzed.Results
Children of the plagiocephalic group showed more often orthodontic alterations compared to the others. Especially the frequencies of a class II malocclusion (36 vs. 14 %), an edge-to edge bite (28 vs. 12 %), and deviations of the midline (38 vs. 16 %) were conspicuous. However, none of the differences was significant (p > 0.003). Of all observed mandibular asymmetries, 69 % appeared as a shift to the contralateral side of the former flattened occipital region.Conclusion
Positional head deformity might be associated in some cases with a higher prevalence of occlusal abnormalities in primary dentition.Clinical relevance
Positional plagiocephaly interfaces medicine and dentistry. As it is a common disorder, this etiology has to be considered in the prevention and therapy of malocclusion.15.

Introduction
The question of whether diabetes mellitus can influence the outcome of root canal treatment (RCT) remains unclear. The aim of this systematic review and meta-analysis was to analyze scientific available evidence on the association between diabetes and the presence of radiolucent periapical lesions (RPLs) in root-filled teeth (RFT).Methods
The review question was as follows: in adult patients who had endodontically treated teeth, does the absence or presence of diabetes result in an increase in the prevalence of RPL associated to RFT? A systematic MEDLINE/PubMed, Wiley Online Database, Web of Science, and Scopus search was conducted using the following MeSH and keywords: Diabetes Mellitus OR Diabetes OR Diabetic OR Hyperglycemia, AND Endodontics, Periapical Periodontitis, Periapical Diseases, Apical Periodontitis, Periradicular Lesion, Periapical Radiolucency, Radiolucent Periapical Lesion, Root Canal Treatment, Root Canal Preparation, Root Canal Therapy, Root Filled Teeth, Endodontically Treated Teeth. Seven studies reporting data on the prevalence of RPL associated to RFT both in diabetic and control subjects were included.Results
After the study selection, seven epidemiological studies fulfilled the inclusion criteria, representing data from 1593 root canal treatments, 1011 in non-diabetic control subjects, and 582 in diabetic patients. The calculated pooled odds ratio (OR = 1.42; 95 % CL = 1.11–1.80; p = 0.0058) indicates that diabetic patients have higher prevalence of RFT with RPLs than controls.Conclusion
Available scientific evidence indicates that diabetes is significantly associated to higher prevalence of periapical radiolucencies in endodontically treated teeth, being an important putative pre-operative prognostic factor in RCT.Clinical relevance
Taking into account that diabetes is the third most prevalent chronic medical condition among dental patients, endodontic providers should be aware of the relationship between the outcome of endodontic treatment and diabetes.16.
Objectives
The aim of this study was to examine different central bearing point methods in patients with and without temporomandibular disorders (TMD) by an experienced and unexperienced examiner.Material and methods
The 20 fully dentulous subjects were screened for TMD based on the Research Diagnostic Criteria for TMD and distinguished into functional impaired and functional healthy groups. The mandibular relationship was recorded by an electronic central bearing tracing device (IPR-System, IPR GmbH, Oldenburg, Germany) with an integrated pressure sensor. Three bite registration methods were performed using this device: initial neuromuscular position, final neuromuscular position after dynamic sequences with the intraoral pin (=neuromuscular deprogramming), and centric relation guided manually by an experienced and an unexperienced examiner.Results
The neuromuscular positions before and after neuromuscular deprogramming were not significantly different (paired t test as a group comparison test: transverse: p = 0.369; sagittal: p = 0.486). Both positions were significantly anterior in comparison to the manually guided centric relation (paired t test as a group comparison test: p < 0.0001). The neuromuscular positions before and after deprogramming tend to have high scattering values.Conclusion
By means of the central bearing point method, the manually guided centric relation is the one which is sufficiently reproducible. It seems doubtful to take the significant anterior neuromuscular position for a definite reconstruction.Clinical relevance
Using the central bearing point method, the manually guided centric relation should be preferred, whereas the neuromuscular position should not be used for definite reconstructions.17.

Objectives
The current study investigated the association between VDR EcoRV (rs4516035), FokI (rs2228570), ApaI (rs7975232) and TaqI (rs731236), CYP27B1 (rs4646536), CYP24A1 (rs2296241), and MTHFR (rs1801133) gene polymorphisms and risk of oral lichen planus (OLP) occurrence.Materials and methods
The study group consisted of 65 oral lichen planus patients and 100 healthy blood donors in the control group. Single nucleotide polymorphisms were genotyped by real time PCR or PCR-restriction fragment length polymorphism (RFLP) method.Results
Heterozygous as well as mutated genotype of vitamin D receptor (VDR) FokI (rs2228570) polymorphism was associated with increased oral lichen planus risk in comparison with wild type genotype (odds ratio (OR) = 3.877, p = 0.017, OR = 38.153, p = 0.001, respectively). A significantly decreased OLP risk was observed for heterozygous genotype of rs2296241 polymorphism in CYP24A1 gene compared with the wild type form (OR = 0.314, p = 0.012). VDR gene polymorphisms ApaI and TaqI were in linkage disequilibrium (D’ = 0.71, r 2 = 0.22). Identified haplotype AT was associated with decreased OLP risk (OR = 0.592, p = 0.047).Conclusion
Our results highlight the possible important role of VDR FokI (rs2228570) and CYP24A1 rs2296241 gene polymorphisms for oral lichen planus susceptibility.Clinical relevance
Identification of new molecular biomarkers could potentially contribute to determination of individuals with OLP predisposition.18.

Objective
Dermoid and epidermoid cysts are rare cysts of the head and neck region, which should be considered in differential diagnosis of sublingual mass, constituting 0.01 % of all oral cavity cysts. There are suspected theories regarding the basis of the pathology.Case Report
30-year-old male referred to our clinic with a chief complaint of sublingual mass which had been present for many years but the lesion enlarged over the past 3 years. MRI examination revealed a giant cystic mass which was 3.6 × 3.9 mm in diameter and medially located at sublingual region.Treatment and Prognosis
Intraoral approach was preferred for surgery and no recurrence or complaints were detected during follow-up period.Conclusion
When a cystic mass is detected on the floor of oral cavity, we must consider dermoid cysts for differential diagnosis. Surgery is the only treatment. If possible, intraoral approach should be preferred because of its perfect cosmetic results.19.
Objectives
The purpose of this study was to evaluate the prevalence of anatomical variations of the nasal cavity and ethmoid complex on cone-beam computed tomography (CBCT) images.Methods
The CBCT images of 322 patients were evaluated retrospectively. The anatomical variations of the bilateral nasal cavity and ethmoidal complex were evaluated in four categories, namely nasal septum, turbinates, ethmoid air cells, and crista galli.Results
The patients comprised 134 males (41.6 %) and 188 females (58.4 %), with an age range of 18–83 years. One or more nasal septum variations were observed in 76.7 % of patients, while variations in the turbinate and ethmoid cell categories were present in 89.4 and 62.1 % of patients, respectively. Overall, 5 % of patients showed pneumatized crista galli.Conclusions
The detailed radiographic examination of the nasal cavity and ethmoid complex is possible and successful on the CBCT images.20.
