RESUMEN

UNLABELLED: The presence of migrants culturally different from inhabitants of the host country is now a widespread phenomenon. It is known that dietary habits and oral hygiene practices vary from country to country, which in turn has a profound effect on oral health. OBJECTIVES: To assess and compare the oral health status of Tibetan school children and local school children of Kushalnagar (Bylakuppe). STUDY DESIGN: A survey was conducted at Kushalnagar (Bylakuppe), in Mysore district, India to assess the oral health status of Tibetan school children (n = 300) and local school children (n = 300) and compared using World Health Organization oral health proforma (1997). RESULTS: The proportional values are compared using chi-square test and the mean values are compared using Student's t-test. Statistically significant results were obtained for soft tissue lesions, dental caries, malocclusion, and treatment needs. However, results were not significant when gingivitis was compared in the two populations. CONCLUSIONS: Tibetan school children showed higher prevalence of Angular cheilitis, gingival bleeding, dental caries experience, malocclusion, and treatment needs in comparison with non-Tibetans. Among the Tibetan school children, the requirement for two or more surface filling was more.

RESUMEN

AIMS: The aim of this study was to compare the ex-vivo effects of different root canal sealers on the fracture resistance of endodontically treated teeth. MATERIALS AND METHODS: Seventy-five freshly extracted human mandibular premolars were used for the study. The length was standardized to 14 mm and all the teeth were biomechanically prepared and divided into five different groups based on the type of root canal sealers used. Group I:- Roeko seal + gutta percha, Group II: AH plus ® root canal sealer + gutta percha, Group III: PULPDENT root canal sealer + gutta percha, Group IV: Zinc oxide-eugenol sealer + gutta percha, Group V: Control (unobturated teeth). The teeth were embedded in acrylic resin blocks and compressive strengths were measured using universal testing machine (Instron). STATISTICAL ANALYSIS USED: One-way ANOVA, unpaired t- test. RESULTS: Data obtained were statistically evaluated using one-way ANOVA and unpaired t-test. All groups showed a statistically significant result (P < 0.05). Teeth obturated with Group I and Group II showed higher resistance to fracture than teeth obturated with other three Groups. It was seen that the teeth obturated with group III showed a better fracture resistance than Group IV and there was no statistical significance found between Group and Group V. CONCLUSIONS: From this study, it has been concluded that both the resin based sealers that were used in this study were equally effective compared to that of the zinc oxide-based sealers and the control group. However, no significant results were obtained when the comparison was made between zinc oxide-eugenol and gutta-percha and the control group.

RESUMEN

Bacteriocins are bacteriocidal proteinaceous molecules produced by the Gram-positive bacteria not active against the produced strain. Many investigations have revealed that certain bacteria using antibacterial or the inhibitory substance inhibit some other bacteria. A study was conducted in a group of 60 children to ascertain whether any correlation exists between the proportion of salivary bacteria inhibiting and stimulating Streptococcus mutans and the oral health indices (DMFT, deft and Community Periodontal Index of Treatment Needs). A definite inverse correlation was observed between the percentage of salivary inhibiting S. mutans and untreated carious teeth (UCT).

RESUMEN

A melanotic macule is a benign pigmented lesion of oral cavity characterised by increase in melanin pigmentation. Presented here is a case report of 12 year old girl with black pigmented area on right buccal mucosa. An excision biopsy was done which confirmed the diagnosis by as melanotic macule.

RESUMEN

Foresteir's disease or Diffuse idiopathic skeletal hyperostosis (DISH) involving the cervical vertebrae in two patients is being presented as an uncommon cause of snoring and dysphagia. The radiological features of the giant osteophytes involving the cervical vertebrae are detected on routine skiagrams of the neck. A review of literature over ten years showed no such record of such a lesion occurring in C1-C2 vertebrae, whereas the occurrence in the lower cervical vertebrae is occasionally seen causing dysphagia. The relative merits of the surgical approaches are discussed.

RESUMEN

Vecuronium bromide (Norcuron, Organon, Inc., West Orange, NJ) is a common neuromuscular blocking agent used to facilitate mechanical ventilation. Cases have been reported in which prolonged use of vecuronium resulted in severe motor neuropathy, with or without myopathy. However, the time course of recovery, the functional prognosis, and the use of inpatient rehabilitation is not well-established. We are reporting the functional recovery of two cases with the diagnosis of severe vecuronium motor neuropathy and/or myopathy. The patients presented with pneumonia and meningococcemia, respectively, and received vecuronium during ventilatory support, which lead to quadriparesis. In one patient, vecuronium toxicity occurred while neuromuscular junction monitoring was in place. Significant improvement was noted during an average of 3 to 4 wk in a comprehensive inpatient rehabilitation program, documented by the improvement in total motor Functional Independence Measure scores for patient 1 (from 15 to 71) and for patient 2 (from 65 to 84). In addition, the distal compound motor amplitudes showed a 4-fold increase for the ulnar, a 7-fold increase for the median, an 11-fold increase for the peroneal, and a 3-fold increase for the tibial nerves on follow-up nerve conduction studies correlating with neurologic recovery. In summary, even when patients present with quadriparesis, the recovery after vecuronium toxicity appears to be favorable.

RESUMEN

The purpose of this study was to determine if age is significant in functional recovery in acute, traumatic central cord syndrome (CCS). Recovery of ambulation, ADL status, and bowel and bladder function were evaluated. A retrospective study tested the hypothesis that functional recovery in 51 consecutive CCS patients was better in younger patients than in older patients. Four patients, all more than 50 years, died. Ability to ambulate independently at discharge was compared in 30 patients younger than 50 years with 21 patients 50 years or older. Results showed that 29 of 30 (97%) of the younger patients were ambulatory compared to seven of 17 (41%) of the older patients (p less than .002). The younger patients were also able to achieve independence in self-care and bowel and bladder function in a significantly greater proportion. The prognosis for functional recovery in acute traumatic CCS should consider the patient's age. The prognosis is less optimistic in older patients, but it is considerably more favorable in younger patients than previously reported.
