In this randomized controlled trial, results for short (6-mm) implants were similar to those for longer (≥10-mm) implants in augmented bone. Short implants might be preferable to SFE, because the treatment is faster and less expensive. Long-term randomized controlled trials are required to confirm these results.

BackgroundMany young paediatric patients with severe dental caries receive dental treatment under general anaesthesia. Oral health-related quality of life (OHRQoL) can be evaluated to assess the outcome of dental general anaesthesia (DGA) treatment. The aim of our study was to examine the OHRQoL of young Lithuanian children in need of DGA treatment and analyse the impact of DGA treatment on children’s OHRQoL.MethodsWe carried out a prospective clinical follow-up study on OHRQoL among all young Lithuanian child patients who received DGA treatment at the Lithuanian University of Health Sciences Hospital during 2010–2012. The study consisted of clinical dental examinations of patients younger than six years, data collected from their patient files, and an OHRQoL survey completed by their parents prior to the child’s dental treatment. We conducted a follow-up OHRQoL survey one month after the DGA treatment. The Early Childhood Oral Health Impact Scale (ECOHIS) and its effect size (ES) served to evaluate children’s OHRQoL, and the Wilcoxon signed-rank test served for statistical analyses.ResultsWe obtained complete baseline and follow-up data for 140 and 122 participants, respectively (84.7% follow-up rate). Pain and eating problems among children and parents feeling upset and guilty were the most frequently reported impacts at baseline. The parents reported greater impacts on boys than on girls. The ECOHIS score decreased significantly (69.5%, p < 0.001) after DGA treatment, revealing a large ES for the child (1.6) and family (2.4) sections of the ECOHIS.ConclusionsThe OHRQoL of young Lithuanian children requiring DGA treatment is seriously impaired. Dental general anaesthesia treatment results in significant improvement of the children’s OHRQoL. The children’s parents also greatly appreciate this treatment modality for its positive impact on the family’s quality of life.

The aim of this study was to evaluate the success of one-stage implants placed at the time of alveolar bone augmentation using simultaneous guided bone regeneration technique with a collagen barrier membrane in patients suffering from insufficient bone width. Seventeen patients were treated with 20 one-stage OSTEOFIX (Oulu, Finland) implants using simultaneous guided bone regeneration technique. Dehiscence defects were filled by bovine bone mineral Bio-Oss and covered with collagen membrane. Clinical and radiographic parameters of the peri-implant conditions were assessed at the moment of prosthesis placement and at 1- and 5-year follow-ups. Diagnostic dehiscence defect measurements after implant placement showed that the mean vertical defect varied from 3.8 mm to 10.0 mm. At the moment of prosthesis placement and at 1- and 5-year follow-ups all implants were stable, painless and without biological complications. Clinical and radiographic parameters of the peri-implant conditions remained stable during follow-up. The cumulative implant survival rate was 100% after the 5-year observation period and the success rate for all pooled implants was 90%. The present study showed predictable treatment outcomes recorded after 5 years of function for one-stage OSTEOFIX (Oulu, Finland) oral implants placed simultaneously with guided bone regeneration using collagen membrane and deproteinized bovine bone mineral.

The aim of this study was to investigate the severity of infraorbital nerve injury following zygomaticomaxillary complex fractures and to estimate the treatment methods facilitating its functional recovery. A total of 478 patients with unilateral zygomaticomaxillary complex fractures were treated. Infraorbital nerve sensory disturbances were diagnosed in 64.4% of the patients. Injury of the infraorbital nerve was expressed as asymmetry index, which was calculated as a ratio between the affected side and the intact side electric pain detection thresholds at the innervation zone skin before treatment and 14 days, 1, 3, 6 and 12 months postoperatively. A mean asymmetry index of 0.6 +/- 0.03 and 1.9 +/- 0.5 was registered for 57 (11.9%) patients with hyperalgesia and for 251 (52.5%) patients with hypoalgesia, respectively. As a result of retrospective analysis of infraorbital nerve sensory disturbances and its functional recovery, infraorbital nerve injury severity was classified as mild, moderate and severe. It was found that the dynamics and outcome of the functional infraorbital nerve recovery depend on the severity of the injury and the presence of infraorbital canal damage. Function was completely recovered within 3 months after treatment in cases with mild nerve injury. In moderate cases, complete recovery was seen within 6 months and in 34.6% of the severe cases, within a 12-month period after treatment when infraorbital nerve decompression was performed according to the stated indication. Treatment based on infraorbital nerve injury classification offers a better prognosis for complete recovery of the infraorbital nerve function.

The aim of this study was to compare the bone regeneration in the anterior maxilla between bone substitutes and autologous platelet concentrate in alveolar ridge preservation.Forty patients requiring tooth extraction in anterior maxilla were randomly allocated to the four following treatment modalities: spontaneous healing (control), natural bovine bone mineral covered with resorbable native collagen membrane (BBM/CM), freeze-dried bone allograft covered with resorbable native collagen membrane (FDBA/CM) and Plasma Rich in Growth Factors alone (PRGF). Bone biopsies and histomorphometrical analysis were performed after 3 months of healing. The following parameters were assessed: newly formed mineralized tissue, the newly formed non-mineralized tissue, and the residual bone grafting material (if applicable). Statistical analysis was performed for descriptive analysis and to compare the parameters of the bone regeneration between the study groups. Histomorphometrical analysis revealed the highest new mineralized tissue formation in PRGF group. Statistically significant differences in new mineralized tissue formation were found between control/PRGF (46.4±15.2% vs 75.5±16.3%), control/(BBM/CM) (46.4±15.2% vs 20.3±21.9%), control/(FDBA/CM) (46.4±15.2% vs 7.2±8.6), PRGF/(BBM/CM) (75.5±16.3 vs 20.3±21.9%), and PRGF/(FDBA/CM) (75.5±16.3 vs 7.2±8.6) groups. The new mineralized tissue formation was in the following order: PRGF &gt; control &gt; BBM&gt;FDBA. Alveolar ridge preservation in aesthetic zone with PRGF has been the most effective in bone regeneration of the alveolar ridge.

ObjectivesTo systematically examine influence of soft tissue condition and plaque accumulation around dental implants on peri-implantitis development.Material and MethodsAn electronic literature search was conducted of two databases - MEDLINE (Ovid) and EMBASE from 2011 to 2016. Sequential screenings at the title, abstract, and full-text levels were performed. Clinical human studies in the English language that had reported soft tissue condition or plaque accumulation influence on peri-implantitis development were included. The resulting articles were independently subjected to clear inclusion and exclusion criteria by two reviewers as follows.ResultsThe search resulted in 8 articles meeting the inclusion criteria. These studies reported gingival index, plaque index, pocket depth, bleeding on probing/modified bleeding index for sites with “adequate” (≥ 2 mm) and “inadequate” (< 2 mm) width of keratinized mucosa. Results demonstrated that the amount of keratinized mucosa has little influence on soft-tissue inflammation in the presence of good oral hygiene. However, suboptimal oral hygiene due to difficulty in access for plaque control in the areas of minimal keratinized mucosa may lead to greater tissue damage.ConclusionsIn cases with insufficient keratinized gingiva in the vicinity of implants, the insufficiency does not necessarily mediate adverse effects on the hygiene management and soft tissue health condition. Nonetheless, the risk of the increase of gingival index, plaque index, pocket depth, bleeding on probing/modified bleeding index is present. Therefore, the presence of an appropriate amount of keratinized gingiva is required.

Trigeminal neuralgia (TN) is a rare neuropathic disorder with an excruciating facial pain. The unpredictable pain attacks may result in anxiety and depression. The aim of this study was to determine and to evaluate the level of chronic facial pain and its association with the appearance of anxiety and depression. Materials and Methods. A total of 30 patients with TN and chronic facial pain (group A, 25 women and 5 men; mean age, 64.2±3.2 years) and 30 with atypical facial pain (group B, 26 women and 4 men; mean age, 64.8±1.9 years) were examined. A standardized diagnostic protocol was applied to all of them, which consisted of the following: 1) demographic data and estimation of overall pain on a visual analog scale; and 2) evaluation of emotional status using the Sheehan Disability Scale, Covi’s Anxiety Scale, and Beck Depression Inventory. Results. The intensity of facial pain was much higher in the group A than the group B (89.7±2.5 versus 44.0±2.9, P<0.0001). Besides, the group A reported increased scores on the disability and anxiety symptom scales (17.4±1.3 and 9.7±0.3 vs. 6.4±0.7 and 3.6±0.1, respectively, P<0.0001). Severe (46.7%) or moderate (30%) levels of depression were documented in the majority of patients in the group A, while the group B did not show depressive symptoms (P<0.0001). Conclusions. Patients with TN and chronic facial pain had a significantly higher level of pain perception, and they presented the higher level for anxiety and depression than those with atypical facial pain. A multidisciplinary approach is needed for the additional assessment of emotional status of patients in order to improve the efficacy of treatment and patients’ quality of life.

Objective. The aim of this study was to evaluate the dependence of the condition of the microflora of the oral cavity on the etiology of xerostomia, patients’ sex, age, degree of hyposalivation, and duration of the sense of dryness. Material and Methods. A total of 64 patients with complaints of oral dryness referred to the Clinic of Oral and Dental Diseases, Hospital of Lithuanian University of Health Sciences, for consultation during the period from 2003 to 2005 were selected for the study. The etiological factors of xerostomia were as follows: radiotherapy (PRT) to the maxillofacial area, Sjögren’s syndrome (SS), and xerogenic medications, tricyclic antidepressants (TCAs). Results. There were 50 women and 14 men. Their mean age was 60.5±1.6 years. All the patients in the PRT group had high counts of Candida spp. as compared with percentages of patients in the TCA and SS groups (100% vs. 66.7% and 56.2%, P<0.05). Patients’ age and sex in different etiology groups had no significant impact on the condition of their oral microflora. There were equal percentages of patients with deficient and normal salivation in the TCA group (44% in both the groups; P<0.01). All the patients in the PRT group had pronounced hyposalivation (P<0.002). A significantly greater percentage of patients with severely reduced salivation had high counts of Lactobacillus spp. (P<0.01). Significantly greater percentages of patients with the clinical duration of xerostomia of up to 6 months had high counts of Lactobacillus spp. and Candida spp. colonies. Conclusions. In patients with xerostomia, the condition of the microflora of the oral cavity and impairment of major salivary gland function varied according to the etiology of the disease. The level of hyposalivation and the duration of xerostomia were found to have a significant impact on the microflora of the oral cavity.
