Myoepithelial sialadenitis with metachromatic matrix: A diagnostic pitfall. A case of salivary gland swelling in a paediatric patient evaluated by fine needle aspiration cytology.

Fine needle aspiration cytology (FNAC) is generally characterized by a high diagnostic accuracy in differentiating non-neoplastic/inflammatory lesions from neoplastic lesions of the salivary glands. Lymphoepithelial sialadenitis/myoepithelial sialadenitis is exceedingly rare in paediatric patients and is characterized by a diffuse, often bilateral, salivary gland enlargement and the differential diagnosis may sometimes be difficult. We report the case of a 10-year-old boy who presented with a swelling of the left parotid gland investigated by ultrasound salivary gland FNAC.

Association of tooth agenesis with dental anomalies in young subjects.

AIM: The aim of the current study is to correlate the presence of tooth agenesis with other dental anomalies in 7- to 15-year-old patients. MATERIALS AND METHODS: After evaluating 4000 panoramic radiographs of young subjects, 430 revealed the presence of tooth agenesis, except for the third molar, and are retrospectively observed and compared with a non-agenesis control group of 500 subjects, in order to investigate the existence of other associated dental anomalies in both groups. RESULTS: The prevalence of tooth agenesis was approximately 9.30% (430/4000); no significant gender differences were found. A significantly higher prevalence of microdontia of the maxillary lateral incisors (p < 0.001) and delayed tooth development (p = 0.0001) was observed in the agenesis group (group A), while delayed development of permanent teeth (p < 0.0001) and hypo-occlusion of the primary molars (p = 0.0130) were found in the control group (group B). CONCLUSIONS: Agenesis patients presented a significantly higher prevalence of microdontia of the maxillary lateral incisors. Instead, non-agenesis patients presented a high prevalence of delayed permanent tooth development and hypo-occlusion of the primary molars. Moreover, further researches are needed to elucidate the role of genetics and environmental factors in the current sample group.

Surgical Management of Frenula: Laser Therapy Compared with Z-Frenuloplasty Technique

Abstract Objective: To compare intra- and post-operative consequences associated with Z-frenuloplasty and laser therapy for both upper labial and lingual frenulectomies. Material and Methods: Clinical data of 120 consecutive patients with a mean age of 11 years and 2 months (age range from 9 years and 1 month to 14 years and 3 months) with hypertrophic labial and lingual frenula were assembled. Of the 70 labial frenula, 35 were removed through Z-frenuloplasty (Group 1) and 35 with laser (Group 2); of 50 lingual frenula, instead, 25 were extracted through Z-frenuloplasty (Group 1A) and 25 with laser (Group 2A). The cutting device was Laser Diode Handy 10 in continuous mode. Finally, the time of the surgery, pain and swelling were measured 24-48 hours after the removal. VAS scale was used. Results: The time of the surgery, VAS score after the removal and the swelling were lesser in Group 2 and 2A. Conclusion: Both Z-frenuloplasty and Laser therapy are valid instruments to remove frenula. Moreover, laser offers more advantages like less use of anesthesia, no bleeding in the operating phase, no need for suturing, a faster tissue healing and minor limitations in speech and nutrition.
