Periodontitis is an inflammatory disease of the supporting tissues of the teeth caused by specific microorganisms, resulting in destruction of the periodontal ligament and alveolar bone. Progressive loss of alveolar bone is the salient feature of periodontal disease. Accurate detection of periodontal disease with the use of radiographs helps in diagnosis, treatment and prognosis.The present study aims to compare the efficacy of conventional intraoral periapical (IOPA) and direct digital radiographs (RVG) in detecting interdental alveolar bone loss using intrasurgical (IS) measurements as the gold standard.Thirty patients elected to undergo periodontal flap surgery with periodontitis computing to 60 interdental alveolar defects on mandibular first molars were considered. IOPA and RVG were captured using standardized techniques. Bone loss measurements in IOPA and RVG were compared to the IS measurements.Statistical analysis was carried out using student t test and ANOVA with the help of SPSS software and p-value <0.05 was considered as significant.Both IOPA and RVG underestimated the bone loss measurements when compared to IS measurements which was statistically significant (p<0.0001). Bone loss measurements in RVG were closer to IS measurements than IOPA.Both the radiographic techniques IOPA and RVG underestimated bone loss by 1.5-2.5 mm. RVG was superior to IOPA for the detection of interdental bone loss due to reduced time and radiation exposure to obtain the same diagnostic information.

Anemia of chronic disease (ACD) is one of the most common forms of anemia. It is defined as anemia occurring in chronic infections, inflammatory conditions or neoplastic disorders which are not due to marrow deficiencies or other diseases, and occurring despite the presence of adequate iron stores and vitamins. Periodontitis is one of the most prevalent chronic inflammatory diseases in humans. This study aimed at finding out if periodontitis, like other inflammatory conditions, could lead to anemia.Thirty chronic generalized periodontitis male patients with hemoglobin levels below 15 mg/dl and serum ferritin values above 30 ng/ml were selected. The various blood parameters recorded at baseline were hemoglobin levels(Hb), erythrocyte count (RBC), erythrocyte sedimentation rate (ESR), mean corpuscular volume(MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC). PERIODONTAL PARAMETERS RECORDED AT BASELINE INCLUDED: plaque index, gingival index, probing pocket depth, clinical attachment level. Periodontal treatment including surgery if required was carried out in all the patients. Periodontal status of patients was monitored by repeating evaluation of periodontal indices at three months and at the end of one year. The hematological values were again measured at the end of one year.The results showed that correction of periodontal inflammation resulted in a significant increase in hemoglobin levels and erythrocyte counts. The erythrocyte sedimentation rate showed a reduction indicating resolution of periodontal inflammation. There was a significant, but much lesser, improvement in MCV, MCH and MCHC values.The results of this study showed that treatment of periodontitis leads to an improvement in hematocrit and other related blood parameters in chronic generalized periodontitis patients with anemia. This provides evidence that periodontitis like other chronic diseases may also cause anemia.

This clinical study was carried out on thirty patients who underwent open reduction and internal fixation for condylar fractures via rhytidectomy/retromandibular approach were evaluated.Group I (rhytidectomy approach) were compared and evaluated clinically and radiologically with Group II (retromandibular approach) for the following parameters like surgical access, duration of surgery, anatomic reduction assessment with relevant radiographs, occlusal discrepancies, need for post operative IMF, facial nerve morbidity, other post operative complications and scarring.There was a statistically significant difference between the two groups in the duration of surgery which was found to be significantly lesser for group II than group I. Access was better in group I. Scar was well camouflaged in patients of Group I when compared to group II.The rhytidectomy (Face-lift) incision which we have used in our study has all the advantages of the retromandibular approach with an added advantage of a less conspicuous scar and a wider exposure of the fracture site. The only disadvantage is the added time required for the closure which is not a concern as the aesthetic outcome of this technique is superior to the other approaches.

The prospective study was to evaluate the incidence, type of neurosensory disturbance (NSD), grade its severity and monitor its recovery occurring in the lower lip and chin due to damage to inferior alveolar nerve following orthognathic surgery involving mandible.The study included 10 patients who have undergone sagittal split osteotomy, genioplasty, and anterior subapical osteotomy (ASO). All the patients examined preoperatively and post operatively 1week, 1 and 6months according to standardized test to clarify the subjective and objective neurosensory status of the injured nerve. Pin prick test, blunt test, two-point discrimator test, brush stoke direction, light touch test, warm and cold test were used bilaterally to lower lip and chin area.Seven patients underwent bilateral sagittal split osteotomy (BSSO) (70%), one patient had BSSO with genioplasty (10%), two patients had BSSO with ASO (20%). During the operation none of the nerves were transectioned, in 60% of patients nerve was not visible and in 40% of patients nerve was seen in distal segment. 70% of patients underwent setback, 30% of patients underwent advancement. The subjective evaluation of the patients revealed the incidence of 90% at 1week, 30% at 1month, 20% at 6months and 10% at 1year post operatively. The altered sensation reported subjectively was hypoesthesia in 50% of the patients, anaesthesia in 40% of the patients. There was 100% recovery in advancement cases and 93.5% recovery in setback cases.There is a high incidence of NSD of the lower lip and chin after BSSO related to advancement, setback, intraoperative nerve encounter and surgical skill. However, recovery of sensation occurs with increasing frequency during the follow-up period. The clinical neurosensory tests are effective guides to study the neurosensory deficit.

This in-vitro study aimed to test the accuracy and reproducibility in detection of incipient occlusal caries and treatment decision making using unenhanced visual-tactile technique and low level magnification by the use of loupes and surgical operating microscope (SOM).Sixty extracted human posterior teeth were assessed by two examiners using ICDAS- II index and CPI- TN probe, with and without magnification. Histopathology was used as gold standard for diagnosis of caries and treatment decision making. Inter and intra examiner reproducibility was determined using Kappa statistics.Intraobserver reproducibility for caries detection using surgical operating microscope ranged from average to good (0.4-0.63). Inter-examiner reproducibility values for treatment decision making using experimental techniques such as unaided (0.40), Loupes (0.51) & SOM (0.63) were similar.
