There is limited data on methicillin-resistant Staphylococcus aureus (MRSA) carriage in dental clinics. 1300 specimens from patients, health personnel, and environmental surfaces of a dental clinic in Egypt were tested for MRSA. Antibiotic susceptibility, biofilm formation, Staphylococcal protein A (spa) typing, SCCmec typing, and PCR-based assays were used to detect mecA, mecC, vanA, Panton-Valentine Leukocidin toxin (PVL), and toxic shock syndrome toxin-1 (tst) genes. Among 34 mecA-positive MRSA isolates, five (14.7%) were PVL-positive, seventeen (50%) were tst-positive, ten (29.4%) were vanA-positive, while none harboured mecC. MRSA hand carriage rates in patients, nurses, and dentists were 9.8%, 6.6%, and 5%. The respective nasal colonization rates were 11.1%, 6.7%, and 9.7%. 1.3% of the environmental isolates were MRSA-positive. Strong and moderate biofilm-forming isolates represented 23.5% and 29.4% of MRSA isolates. 24 MRSA isolates (70.6%) were multi-resistant and 18 (52.9%) harboured SCCmec IV. Among eight spa types, t223 (26.5%), t267 (23.5%), and t14339 (23.5%) were predominant. We noted an alarming genetic relatedness between 7 (20.6%) MRSA isolates and the epidemic EMRSA-15 clone, as well as a combined occurrence of tst and PVL in 3 (8.8%) isolates. Results suggest high MRSA pathogenicity in dental wards highlighting the need for more efficient surveillance/infection control strategies.

Tricho-rhino-phalangeal Syndrome (TRPS) is a rare inherited dysplasia affecting hair, nasal structure and fingers. A literature review indicated that since first described, three types of manifestations have been identified. A Table summarising the oral manifestations demonstrates the variety of presentations. A South African male child presented with the syndrome and was found to show premature eruption of permanent teeth, a finding that has not been previously reported. His oro-facial manifestations also included malaligned and unerupted crowded teeth, bulbosity of the nasal tip and an elongated philtrum and evidence of mild intellectual impairment. A protocol has been developed to guide the future management of these cases.

To assess the prevalence of periodontal disease, orofacial changes and craniofacial abnormalities in patients with thalassemia major (TM). Dental management is discussed. The sample consisted of 54 patients with TM, 31 males and 23 females aged 5.5 to 18.3 years, with the mean age (+/- SD) of 1.6 +/- 3.2 years. The sample was divided into two subgroups according to age. A similar number of unaffected control group matched by age and sex served as a control. Clinical and radiographic examinations were carried out to assess the prevalence of changes caused by this disorder. Student's t-test was used to compare the means between thalassemic group and the control group. The Chi-square test was employed to determine statistical differences in frequencies between the two groups.. Poor oral hygiene and gingivitis were observed in 61.1% and 43.0% of the thalassemic patients, respectively. The overall mean plaque score was 1.66 +/- 0.51 and gingival score 1.43 +/- 0.59. In all tested periodontal parameters, a higher frequency and severity were noted in the thalassemic patients compared with controls. More than half of the patients exhibited frontal bossing, saddle nose and to less extent maxillary protrusion; giving in severe cases (16.7%) a "chipmunk" like appearance. Dental discoloration and pallor oral mucosa were noted in 44.4% and 38.9%, respectively. Dental/jaw pain was reported by 40.0% and headache by 29.6% of the patients. Increased overjet was evident in 25.9% of the patients. The majority of the patients had thickened frontal bone (66.7%), and thinned inferior border of the mandible (64.6%). Widened dipolic spaces and spiky roots and were observed in one-third of the patients. The ramus length and width in the patients were significantly smaller than in controls (P < 0.001).. TM may particularly diagnose through orofacial abnormalities. Dentists required understanding the complications and management of the disease.

Some patients complain of altered sensation in the mouth following nasal surgery. A prospective study of 60 consecutive patients who underwent a total of 83 intranasal procedures revealed that this was a common complication, particularly following submucous resection (SMR) or intranasal antrostomies. The area affected by pain/parasthesia appears to be anatomically related to the surgical procedure(s) performed.

When a clinician is confronted with an apical radiolucent lesion he must follow an organized thought process and diagnostic technique prior to therapy. This technique employs the collection of data, called the diagnostic data base, and radiographic data. The diagnostic data base and radiographic data combined with the results of the vitality tests will provide the clinician with an appropriate working diagnosis. If the data support a diagnosis of radiolucent lesion associated with a nonvital tooth then endodontic therapy should be provided and the patient should be seen on a routine follow-up basis. Dr. H. M. Worth has most elequently summarized the responsibilities of the clinician as follows: "The endodontist cannot content himself with sufficient knowledge to deal with apical infections only, for he encounters a great number of diseases; it is necessary for him to be reasonably well informed on the radiographic appearances of most of the abnormalities and diseases that occur in the jaws."
