It is extremely important to assess variations between the most used radiographs in dental practice, since minimum distortion on obtained images may change diagnosis, treatment plan, and prognosis for the patient. For this, the distance between the enamel-cementum junction and the alveolar bone crest was measured on conventional and digitized periapical, bitewing, and panoramic radiographs and compared among them. From a total of 1484 records, 39 sets of radiographs that fulfilled the inclusion criteria of the study sample were selected. The measurements were grouped according to the intensity of bone loss. Statistically significant difference was found in the averages of the measurements assessed in radiographs with absence of bone loss between conventional panoramic and periapical radiographs, between digitized panoramic and periapical radiographs and between digitized bitewing and panoramic radiographs. By analyzing the results of this work and considering the research protocol used, one can conclude that small losses in height of alveolar bone crest observed in panoramic radiographs should be cautiously evaluated, as they may be overestimated....
This study aims to determine the causes and pattern of tooth mortality among adult patients visiting the dental clinics of Ajman University of Science and Technology (AUST), Faculty of Dentistry, UAE and compare results with other international studies. The study was also aiming to determine the future preventive measures.\nMaterials & method: Retrospective study design, 1000 files of the adult patients from September 2006 till April 2007 have been selected randomly. \nResults: Out of 519 patients undergone extraction, 1301 teeth were extracted for different reasons. The results of the study show that the major reason for extraction was caries 40.96% followed by periodontitis 33.7%, 21.1% for the endo-perio. lesions. Patients were commonly from the twenties age group 28.1%. Male patients were in general more than female patients except in the age group (12-30). Minitab 15 was used to statistically analyze the data. \nConclusion: Caries was the main reason for tooth loss in AUST dental clinics among all patients, upper molars were the teeth most commonly extracted and the twenties age group was the commonest age group came for extraction...
Background\nThere has been little discussion about the importance of oral management and interferon (IFN) therapy, although management of the side effects of therapy for chronic hepatitis C has been documented. This study determined whether dental problems delayed the initiation of IFN therapy for hepatitis C virus (HCV)-infected patients.\nResults\nWe analyzed 570 HCV-infected patients who were admitted to our hospital from December 2003 to June 2010 for treatment consisting of pegylated IFN (Peg-IFN) monotherapy or Peg-IFN/ribavirin combination therapy. The group comprised 274 men and 296 women with a mean age 57.2 years. Of the 570 patients, six could not commence Peg-IFN therapy, despite their admission, because of dental problems such as periodontitis, pupitis, and pericoronitis. The ages of six whose dental problems delayed the initiation of Peg-IFN ranged from 25 to 67 years, with a mean age of 47.3 �± 15.2 years. IFN therapy was deferred for 61.3 �± 47.7 days. Among the six subjects for whom IFN treatment was delayed, only one had a salivary flow that was lower than the normal value.\nConclusions\nTreatment of dental infections is required before IFN therapy for HCV infection can be started. To increase the depth of understanding of oral health care, it is hoped that dentists and medical specialists in all areas will hold discussions to generate cooperation....
This study was undertaken to evaluate the effect of oral administration of lactoferrin (LF) and lactoperoxidase-(LPO-)containing tablet on periodontal condition. Seventy-two individuals with chronic periodontitis were randomly assigned to take either bovine LF and LPO-containing tablets (test group, n=37) or control tablets (control group, n=35) every day for 12 weeks. Periodontal parameters and levels of subgingival plaque bacteria, human and bovine LF, and endotoxin in gingival crevicular fluid (GCF) were evaluated at baseline, 1 week, 4 weeks, and 12 weeks. Significant differences were observed in GCF levels of bovine LF between the test and control groups throughout the study (P<.05). However, clinical and bacteriological parameter values proved comparable between the two groups at 1 week to 12 weeks. Therefore, the effect of oral administration of LF and LPO-containing tablets might be weak on periodontal and bacteriological profile in this study....
The goal of this study was to retrospectively evaluate the clinical outcomes of the Flapless technique in treatment of severe periodontitis after three year. A non-aggressive technique for periodontal bone grafts was developed and tested on 19 subjects. The technique involved scaling and root planing, and the insertion of single grains of bone mineral through the crevicular space into the pocket until it�s completely filled. All patients received monthly periodontal maintenance therapy for six months and then every three months for 2.5 years. Clinical parameters were assessed at baseline and after three years; these included probing depth (PD), clinical attachment level (CAL), and gingival recession (GR); the presence of bone defects was determined radiographically. The signifi cance of the data was confi rmed statistically. There was significant reduction in PD (4.9mm, P<0.005) and CAL gain (3.73mm, P<0.005), and a slight increase of in GR (1.16mm, P<0.005). After six months, it led to radiographic resolution of osseous lesions. Flapless Technique resulted in clinically relevant amounts of CAL gains, shallow pockets, minimal gingival recession, and radiographic osseous defect fill. This minimally invasive approach offers an efficient, safe and well-tolerated alternative for the longterm treatment of severe periodontitis in interproximal pockets of single-rooted teeth....
This is a case report of a patient with idiopathic gingival hyperplasia and an undiagnosed genetic disorder that demonstrated static encephalopathy, mental retardation, developmental delay, seizures, hypotonia, and severe gingival hypertrophy. The clinical dental management and attempts to obtain a genetic diagnosis are described....
The purpose of this study was to investigate the relationship between the number of missing teeth (MT) and the statuses of oral environmental factors (the stimulated salivary flow rate, buffering capacity, and the counts of mutans streptococci, lactobacilli, and Candida) in the elderly. The subjects were 64 elderly subjects with fixed prostheses and 49 who wore removable partial dentures aged over 65 years. We used one-way ANOVA to test for overall differences of the number of MT among 5 oral environmental factors. The significant differences were observed in the lactobacilli counts for different number of MT. The number of MT increased with an increase in the lactobacilli counts with removable denture. In conclusion, for the patients wearing removable dentures, increasing number of MT was associated with an increase in the lactobacilli counts in saliva. For the patients with crowns and fixed partial dentures, the number of MT was not significantly affected by salivary mutans streptococci, lactobacilli, and Candida counts....
The destructive effects of improper use of orthodontic elastic bands are well documented in the dental literature. Numerous cases of iatrogenic periodontal destruction have been reported since 1870. Despite these well-documented hazards, such incidents still occur.\nThis case report describes a patient who was refered to a dentist by his orthodontist for closing the residual midline diastema by composite resin. However, the clinician used an elastic band to close the diastema for better results; thereafter, he restored the lateral teeth. However, a subgingivally hidden elastic band migrated apically and destroyed both the peridontal ligament and the alveolar bone, with subsequent gingival recession. This report describes the approach that was used to save the involved teeth and the root coverage procedure....
Background\nThe relationship between dental anomalies and periodontitis has not been documented by earlier studies. Although psychological factors have been implicated in the etiopathogenesis of periodontitis, very little information has so far been published about the association of anxiety and depression with aggressive periodontitis. The aim of this study was to investigate the association of chronic periodontitis and aggressive periodontitis with certain systemic manifestations and dental anomalies.\nMethods\nA total of 262 patients (100 chronic periodontitis, 81 aggressive periodontitis and 81 controls), attending the Periodontology clinics at Jordan University of Science and Technology, Dental Teaching Centre) were included. All subjects had a full periodontal and radiographic examination to assess the periodontal condition and to check for the presence of any of the following dental anomalies: dens invaginatus, dens evaginatus, congenitally missing lateral incisors or peg-shaped lateral incisors. Participants were interrogated regarding the following: depressive mood, fatigue, weight loss, or loss of appetite; and their anxiety and depression status was assessed using the Hospital Anxiety and Depression (HAD) scale.\nResults\nPatients with aggressive periodontitis reported more systemic symptoms (51%) than the chronic periodontitis (36%) and control (30%) patients (p < 0.05). Aggressive periodontitis patients had a higher tendency for both anxiety and depression than chronic periodontitis and control patients. Dental anomalies were significantly (p < 0.05) more frequent among both of chronic and aggressive periodontitis patients (15% and 16%, respectively), compared to controls.\nConclusion\nIn this group of Jordanians, systemic symptoms were strongly associated with aggressive periodontitis, and dental anomalies were positively associated with both aggressive and chronic periodontitis....
Alcohol and drug abuse are detrimental to general and oral health. Though we know the effects of these harmful habits on oral mucosa, their independent and combined effect on the dental caries experience is unknown and worthy of investigation. We compared 363 \"alcohol only\" abusers to 300 \"alcohol and drug\" abusers to test the hypothesis that various components of their dental caries experience are significantly different due to plausible sociobiological explanations. After controlling for the potential confounders, we observe that the \"alcohol and drug\" group had a 38% higher risk of having decayed teeth compared to the \"alcohol only\" group (P < .05). As expected, those who belonged to a higher social class (OR = 1.98; 95% CI = 1.43-2.75) and drank wine (OR = 1.85; 95% CI = 1.16-2.96) had a higher risk of having more filled teeth. We conclude that the risk of tooth decay among \"alcohol only\" abusers is significantly lower compared to \"alcohol and drug\" abusers....
Periodontal disease is a multifactorial disease having various risk factors, but a dynamic interaction between bacterial products and host response in association with genetic and environmental factors is considered as the primary cause for periodontal tissue destruction in periodontitis. This bacterial-host interaction which is ever-so-present in periodontitis directs us towards utilizing antimicrobial agents along with the routine mechanical debridement. This case report present a case of a female patient with recurrent periodontal infections with gingival enlargement treated with systemic Minocycline in conjunction with the conventional non surgical approach....
