Assessment of age of majority by measurement of open apices of the third molars using Cameriere's third molar maturity index.

AIMS AND OBJECTIVES: Evaluation of biological age of a living subject around the legal cutoff age for adulthood has become a grave concern for forensic experts in India, mainly due to the consequences of criminal obligations in judicial proceedings. Thus, this study was planned to examine the open apices of third molars in discriminating between individuals who are aged 18 years or older and who are not 18 years or older and to assign a cutoff for estimation of the age of 18 years. MATERIALS AND METHODS: Orthopantomographs of 1062 individuals (14 and 23 years) were assessed, to verify Cameriere's third molar maturity index (I3M). The apical ends of the roots of the left mandibular third molar were analyzed. If the apical ends of the roots are completely closed, then I3Mis zero; otherwise, it is calculated as the sum of the distances between the inner sides of the two open apices divided by the tooth length. RESULTS AND CONCLUSION: The sensitivity of the test for 0.08 value was 74.7% for males and 66% for females. Specificity was 83.6% for males and 79.6% for females. The probability that an Indian individual with an I3M<0.08 in 18 years or older is 78% for males and 70.3% for females. I3Mis efficacious to determine age in Indian population.

Morphometric evaluation of soft palate in oral submucous fibrosis--a digital cephalometric study.

The Present study was carried out to evaluate the morphology of soft palate in Oral Submucous Fibrosis (OSF) patients using digital lateral cephalogram. A total number of 70 patients were included in the study (Control group had 35 patients and Study group had 35 OSF patients) were evaluated for soft palate by digital lateral cephalogram. The anterio-posterior length and superior-inferior length of soft palate were measured. The morphology of soft palate was categorized as type 1, to type 6. Different types of soft palate were compared with stages of OSF. Among the Study group (35 patients) 62.9% had Stage 2 OSF. Leaf shaped (Type 1) soft palate was seen commonly in stage 2 OSF whereas butt shaped (Type 3) in stage 3 OSF. In the present study there was statistically significant difference in length (anterio-posterior) of Type 1 soft palate of OSF patients. In the present study as the OSF progressed to advanced stage there was gradual change from Type 1 and Type 2 variety of Soft palate to Type 3 and Type 6 variety of soft palate. The study observed that there was gradual reduction in the length of soft palate in anterior-posterior direction in OSF patients.

Oral manifestations of lipoid proteinosis: A case report and literature review.

Lipoid proteinosis is an uncommon autosomal recessive metabolic disorder that presents in early life with hoarseness and pox-like acneiform scars involving the skin and mucous membranes. Previous studies have attributed the prevalence of lipoid proteinosis to consanguineous parents. This paper reports a classical case of lipoid proteinosis with oral manifestations but without a history of consanguinity.

Multiple gingival metastasis of adenocarcinoma of the lung.

Metastasis to the gingival soft tissues is an extremely rare phenomenon, and metastasis of multiple lesions (i.e. more than 2 lesions), is even more hard to find. In this study, we have reported a rare case of lung adenocarcinoma, which metastasized to the maxillary (2 lesions) and mandibular gingivae (1 lesion) in a 57 year old male patient. Metastasis was also seen to the vertebrae. The differential diagnosis consisted of acute myelomonocytic leukemia, chronic lymphocytic leukemia, haemangioma, pyogenic granuloma, giant cell granuloma, peripheral fibroma, primary gingival carcinoma and secondary metastasis. Contrast enhanced computed tomography of the lung showed a well-defined mass situated below the right hilum with lower lobe consolidation and pleural effusion on the right side with dorsal spinal metastasis. Excisional biopsy of the lesions was consistent with the diagnosis, and the immunohistochemical analysis was positive for cytokeratin 7, carcinoembryonic antigen (CEA), thyroid transforming factor 1 (TTF1), and negative for vimentin and cytokeratin 20 (CK20).

Cowden syndrome.

Cowden syndrome or multiple hamartoma syndrome is an autosomal dominant condition with variable expressions that result mainly from mutation in the PTEN gene on arm 10q. It is characterized by multiple hamartomatous neoplasms of the skin, oral mucosa, gastrointestinal tract, bones, CNS, eyes, and genitourinary tract. Mucocutaneous features include trichilemmomas, oral mucosal papillomatosis, acral keratosis, and palmoplantar keratosis. Here we present a case of Cowden syndrome in a 14-year-old female patient with the chief complaint of multiple oral papillomatous lesions.

Blue rubber bleb nevus syndrome: prominent oral findings.

Blue rubber bleb nevus syndrome is a rare disorder characterized by multiple cutaneous venous malformations in association with visceral lesions, most commonly affecting the gastrointestinal tract. Oral cavity lesions occur in 59 to 64% of cases. We report a unique presentation of this syndrome in a 25-year-old male patient with prominent oral findings. This is a sporadic case, started during early childhood, progressively increasing in number and size. Oral vascular lesions were part of gastrointestinal involvement. Associated cardiac abnormalities were also observed. An early diagnosis of this syndrome is required as it gets complicated with bleeding, anemia and other systemic complications.
